De Beers Canada Exploration Inc.– Contingency Plan (Fifth Revision: April 30, 2003) 2

1.0 INTRODUCTION "De Beers Canada will … conduct all activities in compliance with applicable legislation and other requirements, providing for the protection of the environment, employees and the public.” – De Beers Canada Environmental Policy

The Contingency Plan of De Beers Canada Exploration Inc. (DBCE), which is found on the following pages, shall be in effect from the current date (end of March 2003) until the end of March 2004. The Kennady Lake (Gahcho Kué) Bulk Sampling Project, which began with the initial delineation and test-drilling of four Kennady Lake kimberlites in January, 1998 (Phase I), is contained within the AK claimblock of DBCE/Mountain Province Diamond Corp./Camphor Ventures (Figure 1); it is situated in the area west of Fletcher Lake and northwest of Cook Lake (Figure 2), which the previous operator informally named "Kennady Lake" and which traditionally is called "Gahcho Kué." The exploration base camp is within claim AK091 and is centrally located relative to the four kimberlite pipes, which are within a 2km radius of the campsite; only three of the kimberlites are being considered as a resource. Camp co-ordinates are latitude 63

o25'48" and longitude

109o12' 00".

Development of the camp, and Phases I and II of the Bulk Sampling Project were conducted under the name, Monopros Limited. The company name was changed to De Beers Canada Exploration Inc. in 2000, prior to commencement of Phase III exploration drilling. It also must be noted that the property is remote; no communities are located nearby, and thus no persons other than personnel and contractors would be affected in the event of an incident. The comprehensive De Beers Canada Environmental Management System (Appendix 1a), which took effect in 2001, is in force in all areas of the NWT and in all provinces where DBCE is conducting exploration activities. The policy, informed by the national De Beers Canada (DBC) Environmental Policy (Appendix 1b), is the key component of this Contingency Plan and enforced in all exploratory activities undertaken by the Company. All employees, whether permanent or casual, are required to familiarise themselves with the DBC policies, especially those operating in a camp. DBCE is keenly aware that planning for an emergency situation is not an option but an obligatory activity, equal in importance to the exploration programme itself. This Contingency Plan is posted in camp, distributed to supervisory personnel for dissemination to staff and provided to contractors. The stated purpose of the Environmental Policy also is the stated purpose of the Contingency Plan: "(To) conduct all activities in compliance with applicable


legislation and other requirements, providing for the protection of the environment, employees and the public.” Each Company geologist or supervisor in charge of a field project completes an in-house monthly activity report, which includes a section on environmental care. These reports are filed and stored within the regional offices. This practice will continue through future exploration programmes, just as it did under all previous exploration programmes. DBCE is committed to working with regulators and other stakeholders, and communicates regularly with them pertaining to land-use activities contemplated and undertaken.

2.0 CAMP FACILITIES

2.1 Facility Description The existing fly-in camp at Kennady Lake/Gahcho Kué first was occupied by DBCE in spring 1997. The current Class A land-use permit issued to DBCE (#MV2001C0065) supersedes the previous permit (#N1998CO902) for occupying the camp and regulates the undertaking of exploration and evaluation programmes. The previous operator on the property, Canamera Geological, established the camp in 1993 and held two prior permits (#N93C025 and #N96C581). Maps depicting the AK claim group and a regional map of the area are presented as Figures 1 and 2. The camp outlay is shown in Figures 3 and 4. The current land-use permit authorises temporary occupancy by up to 100 persons, operation of fuel-storage facilities (consisting of a fuel-drum cache, a temporary, engineered tank farm, and four self-berming bulk-fuel storage tanks and an auxiliary self-berming tank), operation, when required, of an on-ice airstrip in winter, and a greywater sump which receives outflow from the camp kitchen and dry via heat-traced jacketed line. During 1998, with the permission of Land Use, Indian and Northern Affairs, DBCE utilised the existing Canamera cuttings disposal area for containment of drillwater and kimberlite cuttings generated in the winter drill programme. A new site was selected in 1999, and a temporary ice dyke initially retained the cuttings, until the new Cuttings Containment Facility (Figure 3) was constructed. The permanent berms consist of esker sands and gravels, with geotextile membrane liner placed in the embankment and tied into the permafrost foundation. Construction of the permanent Cuttings Containment Facility occurred during February-March 1999. A Type B Water Licence (#N1L2-1725) was issued to DBCE, effective 01 December 1998 through 30 November 2003, for the duration of the exploration programme and any bulk sampling. No water licence was in effect previously. This water licence is renewable and DBCE is currently in the process of applying for a new licence. Because activity at Kennady/Gahcho Kué is still at the exploration stage, the camp is operated seasonally only. At mobilisation, a team of experienced personnel (a Camp Manager, Camp Attendant and one or more Geologists or Supervisors)


reopen and inspect the camp, check inventories, effect any repairs, replace and order any parts or safety supplies that may be required. At demobilisation, the same team cleans up and secures the camp, completes a final inventory check, drains lines (fuel and water), drains water heaters and the potable-water storage tank, and shuts off/disconnects/disengages fuel and power sources and files a final inventory list.

2.2 Facility Personnel Obligations

The obligations and responsibilities of Contingency Plan awareness, maintenance and preparedness begin with the arrival of DBCE employees and contractors. Particularly in the case of new arrivals, supervisors are obliged to acquaint camp staff with Company policies and procedures (DBCE Environmental Management System (EMS) relevant policies and procedures contained in loose-leaf-binder form at each DBCE camp; a binder of governing legislation also is present in each camp office. The comprehensive EMS contains guidance on topics ranging from fuel-handling to aircraft and equipment safety and fire procedures; binders or folders of applicable Material Safety Data Sheets (MSDS) on a wide range of potentially-used products is available in each camp office. The DBCE EMS and Environmental Management Policy are attached as Appendix 1a and 1b. Training and re-training of staff in environmental awareness, petroleum-handling and spills, and the DBC 5-Point Safety System occurs before each programme. A collection of safety materials, territorial and provincial, is also maintained at the DBCE office in Yellowknife; each item in the collection is logged in a regularly updated computer database. New arrivals destined for camp employment familiarise themselves with the DBCE EMS and Environmental Management Policy at the Yellowknife office of DBCE, before departing to the DBCE camp. To further ensure safety, the Kennady / Gahcho Kué camp operates under a strictly enforced dry-camp rule (drug and alcohol-free). A copy of the DBCE Environmental Awareness Training Course is attached as Appendix 1d. In addition, all supervisors on site are to have successfully completed the Mine Safety Supervisor Level I course, whether employees of the contractor (such as a drilling company) or DBCE

In advance of exploration programmes, personnel are required to familiarise themselves with the Contingency Plan and their respective assigned roles, if applicable (in the case of supervisors or acting supervisors). Site personnel are trained in the areas of environmental awareness, site safety, and petroleum-handling and spill response (which latter course includes discussion of emergency procedures for fire response and spill response, as well as distribution of laminated cards with action steps for both fire response and spill response [Figure 10]). In addition, DBCE requires that programme personnel and contractors be trained in basic first-aid and CPR. One person with Advanced Level I first-aid is present on site at all times. All supervisors are trained in/certified in Transport of Dangerous Goods.


2.3 Petroleum Product Transport and Storage

As Kennady Lake/Gahcho Kué camp is a remote facility without all-weather road access, fuel to be used in the 2004 Exploration Programme will be flown to the site or transported into camp via a temporary winter-access route constructed by a qualified contractor (the contractor’s Winter Road Spill Contingency Plan is kept in the camp office). A map depicting the Kennady Lake/Gahcho Kué winter-access route used in 1999, 2001 and 2002 is presented as Figure 6. The location of fuel storage at the camp is shown in Figures 3 and 4. Empty drums are stored together and backhauled to Yellowknife. Aircraft operating during the 2004 Exploration Programme will land on snow-cleared lake ice just offshore of camp.

There are two designated fuel storage sites: a cache of 200L drums (diesel, gasoline (petrol) and Jet-B in sealed containers clearly marked); and a bulk site east of camp (Figure 4), comprised of four CSA-approved 25 000L twinned metal tanks with secondary containment capable of containing 95% of the contents of the primary vessel. Two of the tanks were used during Phase I in 1998, while two additional tanks were installed in January 1999. A single supply line connects all four; a free-standing auxiliary double-walled tank of 111 000L capacity was transported to site in 2001, and is sited immediately east of the four enviro-tanks. A schematic of the enviro-tanks used at the camp is presented as Figure 7. The refuel area comes equipped with on- and off-ramps, a drive-on grate for mobile equipment and underlying 6 000L steel drip pan. Nuna Logistics also temporarily maintained two bulk-fuel storage tanks, contained within an engineered, lined berm, on site from 1999 until 2001. The tanks were emptied in the summer of 2000, and were removed via the winter- access route during the winter of 2001. The lined berm area, known as the “Nuna Tank Farm”, continues to be used as a containment area. It is now used as a containment area for any contaminated snow and fill which is scraped up during operations. The Camp Manager or his designate, a Fuel Monitor, will visually inspect both the bulk fuel storage and drum cache sites daily during active use or at least once a week to check for container leakage or damage, and just as frequently will monitor fuel transfer points. At least once per month, the Camp Manager or Fuel Monitor will measure the volume of diesel in the bulk tanks, and check fittings and lines to verify that no leaking has occurred. Records of these checks are maintained by the Camp Manager or Fuel Monitor, and are available seasonally for inspection by regulatory officials. All four enviro-tanks are accessed from above and do not contain bottom drainage valves. Diesel fuel in 200L drums supplies oil stoves in each of the sleeping tents and common buildings. Drums are filled during winter operations via a sled-mounted tidy tank.


Evaluation drill rigs are supplied from the bulk fuel tanks using a contractor-supplied fuel truck. Exploration drill rigs rely on drum fuel transported to the drillsite. Waste oil is contained in 200L drums and stored on site at the workshop (Figure 4) and at the cement shed. It is incinerated on-site periodically in accordance with applicable regulations, or transported off site for proper disposal. A schematic of the camp incinerator is presented as Figure 8. A list of the current fuel/oil/equipment inventory is attached as Appendix 2. This list is updated every month during camp occupancy. Projected fuel/engine-oil use over the term of the 2004 Exploration Programme activities (should a programme occur) is outlined in Table 1.

2.3.1 Petroleum Product Transfer Pumps, both automatic and hand-held, are used for the transfer of all petroleum products. As a further precaution, smoking is not permitted in fuel areas during transfer, and equipment engines are shut down during fuel transfer. Fuel transfer takes place at the bulk-fuel enviro-storage tanks, the drill rigs, at the helipads, and at the ice airstrip (the latter occurs only if fuel is transferred from a Super Hercules aircraft directly to the bulk tanks). These locations are indicated on Figures 3 and 4. Heating stoves are filled from outside tanks that are positioned on stands with drip pans and absorbent padding. Diesel heating stoves are filled regularly.


2.4 Chemical Use and Storage

The amount of chemicals on site (such as Javex, lubricants, degreasers, etc.) is a total 576L, all but 25L of which are stored in a separate shed apart from the maintenance shop, for safety reasons. A listing of oil/lubes used and maintained at the site is contained in Appendix 2. The remaining 25L represents typical household hazardous materials, such as chlorine bleach and household-type cleaners, which are in the kitchen and dry areas. The seasonal Camp Manager and Camp Attendant regularly monitor all these products; all chemicals are stored in their original, labelled containers. Although spillage may occur accidentally due to breakage, handling and container damage, such incidents are minimised by regular inspection of materials, careful handling and storage (refer to section 5.6).

2.5 Drill Cuttings Containment Area

The containment area has been designed and constructed to retain the drill cuttings and the process water from the drills, as well as precipitation and water from the spring freshet. The containment area will be able to hold several years of kimberlite and process water produced over several evaluation drilling seasons, including any surface water produced during the spring freshet and precipitation. Drill cuttings and process water from evaluation drilling are transferred from the drillsite by a suction truck. The On-ice Drilling Plan is included in Appendix 3. The location of the containment area is shown in Figure 3. Initially, the cuttings were retained behind a specially-designed compacted snow and ice cofferdam until completion of the engineered Cuttings Containment Facility in March 1999. Water and cuttings in the Containment Facility freeze each winter, preventing movement of the material. Construction of the permanent dykes using material taken from a nearby esker, was initiated in February 1999 and was completed during March 1999. The dykes are composed of esker sand and gravel. A geotextile membrane liner has been placed in the embankment and tied into the permafrost foundation. A key trench used ensures that the liner and embankment will be well bonded to the permafrost foundation. The key trench was required at this site to remove the surficial layer of boulders and fractured bedrock. The dykes are designed to control but not completely restrict seepage. During the summer of 2000, it was noted that a higher-than-expected volume of water was seeping through the north dyke. DBCE and its consultants/contractors responded quickly and completed remedial work on the dyke; no observable seepage has occurred in the years since. The water is ponded for sufficient time for the solids to settle out. During the summer months, surplus clean water is decanted over the top of the retaining north dyke, and discharged onto a designated bedrock outcrop (Station #3 under the


Surveillance Network Programme) to minimise erosion. Two decanting events occur each summer season, the second in mid-September prior to freezeup to ensure refreezing of exposed dyke fill materials. Water samples collected from the discharge point must meet the effluent quality requirements of the water licence.

3.0 RISK ASSESSMENT AND MITIGATION OF RISK 3.1 Petroleum Products and Other Fuels

Following is a list of potential sources of fuel spills. Figures 3 and 4 illustrate the camp layout and the location of potential spill sources.

1. Bulk-fuel storage tanks: Leaks or ruptures may occur due to product faults,

accidental damage and overfilling; however, the chance of direct leakage is remote due to the design of the CSA-approved tanks (Figure 7), which are self-berming and allow for 95% secondary containment. Tanks and fuel supply lines have been inspected regularly since setup, and have been inspected by INAC. All four tanks are anchored on tundra mats. Qualified tradesman from JSL Mechanical of Yellowknife installed all piping. A steel drip pan is sited under the refuel deck to receive any drips resulting from vehicle or drum refuelling. As further protection, hydrocarbon-resistant liner underlies the refuel area in front of the bulk tanks, and is covered with esker material. Contaminated fill can be transported by site equipment to the “Nuna tank farm” for aeration, and any spillage in the drip pan can be pumped into refuge drums or into the “Nuna tank farm”.

Diesel for running the drill motors, boiler, gen-set, air compressor, etc. during an evaluation programme will be pumped from the bulk enviro-tanks into a tidy tank mounted at the rear of a contractor-supplied pickup truck. An electrical dispensing station is located at the drive-on grate at the refuel area. The truck is then driven to the drillsite and the fuel transferred.

2. Fuel drums: Leaks or ruptures may occur. This includes drums of diesel and

gas (petrol), as well as waste oil. Fuel cylinders (e.g., propane, acetylene and oxygen for cutting drill casing and other steel): Leaks may occur at valves.

3. Pipes, hoses, and valves: Spillage or leaks may occur due to product

malfunction, damage, or accidentally during fuel transfer.

4. Vehicles and equipment (such as trucks, snowmobiles, loaders, helicopters, aircraft, generators, various machinery, cutting torches, pumps, etc.): Accidents involving leaking or dripping of fuels and oil may occur due to malfunctions, impact damage, lack of regular maintenance, improper storage and faulty operation.

Regular inspection and maintenance, standard practices at all DBCE camps, reduces risks associated with the four categories above. (In the case of


pressurised cylinders, each carries an expiry date; expired or damaged cylinders cannot be refilled by the supplier and automatically are replaced.) In addition, the Company EMS mandates that all DBCE operators or occupants are trained in safe handling procedures. In the 2004 Exploration Programme, spill-response training will be provided to personnel who handle fuels and other petroleum products, and at least one emergency-response drill will be held during the season.

A report will be prepared by the Response Co-ordinator or Project Geologist/Supervisor (refer to Section 5.1) following each spill, noting response time, personnel involved and any problems or deficiencies encountered. This report will be used to evaluate emergency response capability, and remedy any deficiencies, if required. Spill kits are present at areas where fuel is transferred or stored. The number of kits, pads, absorbents and bales of peat for berming will be replenished as and when required. The locations and contents of the spill kits are provided in Appendix 5.

3.2 Waste Disposal

1. Greywater: Greywater from the kitchen and dry is pumped approximately 232m from the camp to a sump designated for this purpose and authorised under the current land-use permit. System failure would be related to pump malfunction, line damage or drips at connections, pipe blockage, freezing, overtaxing of volume capacity and lack of maintenance. Risks are minimal, as the sump is situated at an appropriate distance from the lake and the greywater is free of hazardous substances. Regular maintenance obviates most problems with leaks, drips, heat-trace malfunction, etc.; greywater-line refurbishment is scheduled to occur prior to the next exploration programme.

2. Solid waste: All combustibles, including human sewage from the Pacto toilets in

the latrine, are incinerated on a daily basis. (The Pacto toilets do not require water.) All wastes and waste items that cannot be incinerated are securely packaged, flown out on aircraft backhauls, and disposed of in designated locations off-site (such as the municipal solid waste facility in Yellowknife).

Failures in solid waste disposal may occur due to improper use and maintenance of the incinerator (Figure 8), or damage to the incinerator. DBCE guards against such risks by monitoring during use and inspection during periods of non-use, as well as proper operational procedures.

3.3 Drill Cuttings Containment Area

There are two potential sources of spills from the drill cuttings containment area: the transport of the drill water and fines from the drillsite to the containment area; and a breach in the containment dam structure.


1. Transportation of Drill Cuttings Drill waste includes the process water and fines. The drill water and fines from both are transported to the containment facility by suction truck, as was the case during previous exploration seasons. Spills from the truck could potentially occur should the vehicle be upset during transport. Operation of the suction truck is the responsibility of the contractor, (in past seasons, Kavanaugh Bros. Ltd. of Yellowknife).

2. Dam Structure Failure

Following is a list of possible causes for containment dam failure: • Overfilling the cuttings containment area; • Slumping or settling of the dam due to pressure; • Erosion of the dam by natural elements or seepage; • Heavy precipitation (rain or snowfall) event, resulting in elevated levels

behind the dyke. Regular visual inspections of the disposal facility have been conducted since construction. The visual inspection notes the condition of the dyke slopes, the operating level at the discharge point, the water level relative to the crest of the dyke, and any spills or leaks. A Geotechnical Engineer performs an annual site inspection, during late summer and close to the maximum annual thaw period, to document the performance of the embankments. Previous testing of kimberlite rock at other diamond properties in the North has demonstrated that kimberlite is a relatively stable material with a non-toxic nature.

4.0 RESPONDING TO FAILURES AND SPILLS 4.1 Spill Response Team

4.2 Basic Steps – Spill Procedure

DBCE believes that, in the case of any spill or other environmental emergency, it is necessary to react in the most immediate, safe and environmentally responsible manner. No spill or incident is so minor that it can be ignored. According to the DBCE Environmental Management System, the basic steps of a response plan are as follows:

1. Ensure the safety of all persons at all times.


2. Find and identify the spill substance and its source, and, if possible, stop the process or shut off the source.

3. Inform the immediate supervisor or his/her designate at once, so that he/she

may take appropriate action. (Appropriate action includes the notification of a government official, if required. NWT Spill Report forms are included in Appendix 6.)

4. Contain the spill or environmental hazard, as per its nature, and as per the

advice of the Spill Line and Environmental Advisers, as required.

5. Implement any necessary cleanup or remedial action. 4.3 Basic Steps – Chain of Command

The chain of command with allocated actions, is described below. Figure 9 illustrates the chain of command in the case of a spill.

1. Immediately notify the Project Geologist/Supervisor or Alternate Project

Geologist/Supervisor of any spill. He/she then notifies the Response Co-ordinator.

2. Response Co-ordinator or his/her designate then contacts the 24-Hour Spill Line, if warranted, as follows:

Telephone: (867) 920-8130 Fax: (867) 873-6924

A "Spill Report Form" (6) is filled out as completely as possible before or after contacting the 24-Hour Spill Line.

Other members of the team are notified, such as Project Manager, Regional Manager, Land-Use Adviser.

If the spill is minor (such as dripping of fuel during transfer, which can be absorbed by padding, absorbent crystals, etc.), then the Land-Use Adviser in Yellowknife is notified by phone or fax.

4.4 Other Contacts for Spill Response / Assistance

5.0 TAKING ACTION 5.1 Before the Fact: Preventative Measures

The following actions illustrate the proactive approach of DBCE to environmental care. In addition, these actions minimise the potential for spills during fuel handling, transfer or storage:

1. Fuel transfer hoses with camlock mechanisms are used.

2. Carefully monitor fuel content in the receiving vessel during transfer.

3. Clean up drips and minor spills immediately.

4. Regularly inspect drums, tanks and hoses for leaks or potential to leak. (For

example, fabric-sheathed hose, such as fire hose or petrol-transfer hoses may develop pinholes or surficial cracks from normal weathering out of doors).

5. Drip pans are used at all sites where fuel is transferred and under stationary

machinery (e.g., gen-sets).

6. Train personnel, especially those who will be operators, in proper fuel handling and spill-response procedures. (Training module on petroleum-handling and spill prevention, in addition to environmental awareness module; latter is attached as Appendix 1d).

5.2 After the Fact: Mitigative Measures

1. First steps to take when a spill occurs:

a) Ensure your own safety and that of others around you, beginning with those nearest to the scene.

b) Control danger to human life, if necessary. c) Identify the source of the spill. d) Notify the Project Geologist/Supervisor, as soon as is practical; he/she

in turn notifies the Response Co-ordinator. e) Assess whether or not the spill readily can be stopped. f) Contain or stop the spill at the source, if possible, by following these

actions: i. If filling is in progress, STOP AT ONCE. ii. Close or shut off valves.


iii. Place plastic sheeting at the foot of the tank or barrel to prevent seepage into the ground or runoff of fuel.

iv. Use absorbent materials (sheets, pads, booms) to absorb and contain the fuel spill.

v. Use a patch kit to seal leaks, if practical to do so.

2. Secondary steps to take:

a) Determine status of the spill event. b) If not reported under 1.d), report incident and steps taken to the Project

Geologist/Supervisor, who in turn informs the Response Co-ordinator. c) If necessary, pump fuel from a damaged and/ or leaking tank or drum

into a refuge container. d) Notify the 24-hour Spill Report Line, and receive further instructions

from the appropriate contact agencies listed in Section 4.4(e.g., disposal of contaminated soil or ice/snow in sealed containers for removal from site, etc.)

e) Complete and Fax a copy of the Spill Report Form (Appendix 6). f) Notify permitting authorities. g) If possible, resume cleanup and containment.

5.3 Fuel Spills on Land

“Land” may be defined as soil, gravel, sand, rock and vegetation. Advice on spill containment and cleanup may be obtained from the 24-Hour Spill Line and/or from the two DBCE environmental advisers.

5.3.1 Procedure for Spills on Rock

For hydrocarbon spills on rock outcrops, boulder fields, etc.:

1. Response Co-ordinator or his designate obtains plastic tarp(s) and absorbent sheeting on-site.

2. A berm of peat, native soil or snow is constructed downslope of the seepage or

spill.

3. The tarp is placed in such a way that the fuel can pool for collection and removal (e.g., at the foot of the berm.) If there is a large volume of spilled product, pump the liquid into spare empty drums for sealing and disposal at the incinerator.

4. Absorbent sheeting is placed on the rock to soak up spilled oil, gasoline, etc.

5. Saturated sheeting is disposed of in an empty drum, which is then labelled and

sealed. Alternatively, the pads may be wrung out into the empty drum(s); the drums marked and then secured for eventual incineration of the spill substance. The pads may be reused.


6. The disposal container is then transported to the on-site incinerator.

7. Depending on the nature and volume of the spill, the 24-Hour Spill Line may be

contacted after Step 4 or after Step 5.

5.3.2 Procedure for Spills on Land

1. Response Co-ordinator or his designate obtains plastic tarp(s), absorbent sheeting, Spagh-zorb or other ultra-dry absorbent and any other necessary spill containment equipment, pump, hoses, etc.

2. A berm of peat, native soil or snow is constructed downslope of the seepage or

spill.

3. The tarp is placed in such a way that the fuel can pool for collection and removal (e.g., at the foot of the berm). If there is a large volume of spilled product, pump the liquid into spare empty drums, and dispose of product by burning in the incinerator or by transporting to a solid waste disposal facility.

4. Petroleum-product sheening on vegetation may be controlled by applying a thin

dusting of Spagh-Zorb or other ultra-dry absorbent to the groundcover.

5. Contact the 24-Hour Spill Line. Receive instruction from the appropriate contact agencies listed in Section 4.4 regarding collection of the contaminated soil or vegetation, its removal and site cleanup/restoration.

6. Depending on the nature and volume of the spill, Response Co-ordinator or his

designate implements the spill action plan. 5.4 Fuel Spills on Water

5.4.1 Procedure for Spills on Water

It is important to limit immediately the extent of spills. The following is the procedure to be implemented when an incident occurs:

1. If the spill is small, deploy hydrophobic (water-repellent) absorbent pads on

water. Hydrophobic pads readily absorb hydrocarbons. Alternatively, an ultra-dry absorbent designed for use on water- based spills may be deployed.

2. If the spill is larger, ready several empty drums to act as refuge containers for

the spill.

3. Deploy containment booms on the water surface to "fence in" the spill area gradually and to prevent it from spreading. Keep in mind those environmental factors such as high winds and wave action can adversely affect attempts at spill cleanup.


4. Absorbent booms then can be deployed to encircle and then absorb any hydrocarbon spillage that may have escaped the containment boom.

5. Once a boom has been secured, a skimmer may be brought on-scene to aid in

capture of the hydrocarbon; once captured, the product should be pumped to the empty fuel drums and held for disposal.

6. As soon as possible either during or after the incident, contact the 24-Hour

Spill Line. (This will ensure government agencies are informed.)

7. If the spill is sufficiently large, and cannot be contained by rapid action of personnel present, contact the Mobile Environmental Response Unit for assistance. (Weather permitting, this unit can be flown to an emergency spill site within several hours.)

5.5 Fuel Spills on Snow and Ice

By its nature, snow is an absorbent, and fuel spilled on snow is collected with relative ease, either by shovel, in the case of small-range spills, and by loader, in the case of more extensive spills. Refer to Appendix 3, On-Ice Drilling Plan.

5.5.1 Procedure for Spills on Snow

1. Assess the nature of the spill. Necessary equipment might include shovels, plastic tarp(s), empty drums, loader.

2. Shovel or scrape contaminated snow and deposit in empty refuge drums. If the

spill is more extensive, build peat-bale berms or compacted-snow berms with plastic over top, around the affected area.

3. Either during or immediately after the incident, notify the 24-Hour Spill Line.

Receive instructions on the preferred disposal method (e.g., storage in sealed drums, incineration or deposit in a designated lined containment area on land) from the appropriate contact agencies listed in Section 4.4.

5.5.2 Procedure for Spills on Ice Spills on ice are handled in similar fashion as those on snow. However, as ice presents the added danger of immediate access to water, care must be taken to respond quickly to such spills. Should fuel seep or flow through cracks or breaks in the ice, despite all precautions, assistance should be sought immediately. 1. Construct a compacted-snow berm around the edge of the spill area.

2. Although hard ice will retard or prevent fuel entry to the receiving waters below,

all contaminated snow and ice, as well as objects embedded in the ice (such as gravel) must be scraped from the ice surface and disposed of in an appropriate manner.


3. Contact the 24-Hour Spill Line. Receive disposal instructions (e.g., sealing in drums, burnoff, etc.) from the appropriate contact agencies listed in Section 4.4. Where fuel or oil has escaped to the receiving waters, also contact the 24-hour emergency line of the Mobile Environmental Response Unit.

5.6 Procedure for Chemical Spills

1. Assess the hazard of the spilled material. Members of the emergency-response team who might be susceptible in certain situations, (such as asthmatics, where fumes or airborne particles are evident), should be replaced with alternates.

2. Assemble the necessary safety equipment before response, (e.g., latex or

other protective gloves, goggles or safety glasses, masks or breathers, etc.).

3. Apply absorbents to soak up liquids.

4. Place plastic sheeting over solid chemicals, such as dusts and powders, to prevent their disbursement by wind or investigation by birds or other mammals.

5. Neutralise acids or caustics. Place spilled material and contaminated cleanup

supplies in an empty refuge drum and seal for disposal.

6. Contact the 24-Hour Spill Line. Receive instructions on disposal methods and designated locations from the appropriate contact agencies listed in Section 4.4.

5.7 Procedure for Cuttings Containment Area Spills

Potential containment dam failures are to be addressed as quickly as possible. A spill resulting from the failure of a dam structure would require the construction of a cofferdam to contain the released material, while either temporary or permanent repairs are completed on the failed structure. To minimise the seepage of kimberlite fines and drill wastewater, containment dams should be constructed of materials with low permeability, whenever possible. Rebuilding the dam, or constructing a secondary dam with materials that are locally available would contain the spill. The esker (Figure 5) located at the north end of ‘Esker Lake’, 9.75km northwest of camp, is the main source of granular materials that may be used to effect repairs or construct secondary containment structures. DBCE currently holds a Quarry Permit (#2003QP0009), which authorises use of 500m3 of material from the esker, from February 2003 through February 2004. No material was taken from the esker in the 2003 exploration season. The use of a synthetic liner may be necessary, and this can be flown into the camp or brought in via winter-access route. Liquid portions of the cuttings should be contained within berms or impoundment basins and pumped back to the containment area. Repairs


to the failed structure would take place to standards acceptable to DBCE, its geotechnical advisers and applicable regulatory agencies.

Several potential scenarios for spills from the cuttings containment facility are discussed in the following sections. A contour map indicating the containment facility and direction of drainage, is shown as Site 1 of Figure 4 in EBA’s Containment Facility Design Report, dated 1998 (Project Description Appendix 5). As-built drawings of the facility are included in EBA’s Construction Report submitted to the Water Board as a requirement of the water licence. Copies are maintained at the Kennady Lake camp for reference.

5.7.1 Free-board Level Exceeded and Overtopping of the Dykes The containment facility has been designed and constructed to ensure adequate holding capacity for the projected waste volumes in conjunction with surface runoff produced in a one-in-10 year storm event within the identified watershed. It was designed for two years’ holding capacity with zero discharge, based on projected sample extraction volumes. The containment facility is designed with a minimum freeboard of 1.0m. Regular inspections ensure that this is monitored. Should such a condition occur, further inputs will be curtailed and a plan to immediately reduce the water level by approved discharge, spray evaporation or ice formation, will be implemented that will result in a progressive decline in water levels. Normal operation will resume once water levels are sufficiently lowered to allow additional inputs. If the freeboard level is exceeded to an extreme that the liner is overtopped, then attempts will be made to collect water that was discharged by overtopping. Any processed kimberlite deposited in the valley downstream of the basin would be returned to the containment pond using the on-site Lombardini or Magnum I pumps, other available pumps and heavy equipment. A sump would be excavated in the area that received the discharge. Any water that collects in the sump would be pumped back into the containment pond. Pumping would continue until it can be demonstrated that the water quality is consistent with permitted discharge criteria.

5.7.2 Excessive Seepage

Excessive seepage can be detected as visible seeps on the downstream face of the dyke, or ponded water near the downstream toe of the dyke. Ponded water adjacent to the dyke does not necessarily indicate excessive seepage. The excavation of an interception ditch or sump in the affected area should collect seepage. An engineered sump was constructed downstream of the North Dyke of the containment facility in October 1999. Water that collects in the sump should be pumped back into the containment pond if it does not meet established discharge criteria. Clean water observed at the toe of the dykes does not constitute an adverse environmental impact and can be released, provided the tundra is protected from erosion or thaw-settlement.


5.7.3 Catastrophic Failure

The environmental impact of a hypothetical worst-case failure scenario must be considered should a dyke fail. The risk of catastrophic failure by slope instability or washout is extremely remote. Such a failure could result in rapid release of turbid water. Although highly improbable, should a catastrophic failure occur, water would be released through the natural valley, on which the basin is built, directly into Kennady Lake. Turbid water would reach the lake resulting in a temporary sediment plume that would settle and self-clarify with time. Any processed kimberlite deposited in the valley downstream of the basin could be recovered and returned to the containment pond.

6.0 RESPONSE INVENTORY 6.1 General Equipment

The equipment available to aid in spill response and remediation includes:

1. Heavy equipment used on site for the project includes a Kubota 520 backhoe, a Cat IT38F loader and a Bombardier Muskeg Carrier (tracked skidozer). This equipment will be used for ongoing operation, maintenance and repair of the containment dykes. It will also be available and suitable for use to construct a temporary containment or cofferdam, as well as transport of the 6.5 HP pump and other spill-response equipment in the case of a spill.

Figure 11 shows the specification data for the Kubota backhoe.

2. A 6.5 horsepower diesel-powered Lombardini pump is located at the camp and

can be mobilised to pump water back into the containment facility or another temporary containment structure should a spill or breach in the containment dykes occur. The maximum topographic gradient at the camp is 15m (i.e. the local high of 420m above MSL and Kennady Lake at 405m above MSL). At 15m head, the pump operates at a rate of 18.5 litres per second, or 42m3 per hour.

Figure 12 shows the specification data for the Lombardini pump. (Two additional pumps, a Honda and a Robin, of similar capacity, are currently out for service, and thus are not included in the current inventory). Two 6in Magnum I electric pumps are currently available on site. Figure 13 shows the specification data for a Magnum I pump.

3. Miscellaneous equipment on site also will be made available for spill response

and cleanup, including hand and power tools, shovels (earth and snow), gas-powered fuel-transfer pump, miscellaneous hoses and fittings.


4. Fixed-wing and rotary aircraft can be dispatched to Kennady Lake/Gahcho Kué camp from Yellowknife on short notice. During a drill and/or sampling programme, one or more helicopters may be present on site.

5. A boat with 40HP motor, canoe, snowmobiles with sleds and supply trucks (the

latter available in years when a winter-access route is in operation) to go to and from sites.

6. Fire-safety equipment (includes general-purpose and CO2 extinguishers for

spilled combustibles, buckets and sand.)

A detailed equipment inventory is included in Appendix 2. 6.2 Spill Equipment

Complete spill kits are kept on hand at locations where spills can potentially occur: drillsites, the dock, fuel storage areas, generator shack, incinerator, workshop and the snowmobile shack. A spill kit is also located in the fire station by the tents. Additional spill-response supplies such as plastic sheeting and tarps, and additional absorbent socks, booms and sheets, are located in the absorbents storage shed, adjoining the generator shed.

Typical locations where spill kits may be present include the following:

1. Each drillsite currently in use. (Apart from spill-response, general cleanup in

consonance with land use regulations is effected at each drillsite prior to rigs moving to a new location.)

2. At camp.

3. Beside the bulk-fuel storage tanks (several at all times).

4. At each helipad.

5. At the icestrip pump station in winter, in years when fuel transfer occurs from

drums within a Super Hercules aircraft to the enviro-storage tanks.

6. At the boat dock in summer.

7. At the fuel drum storage area.

There are currently 10 spill kits on site, located at: the bulk fuel tanks (2), Jet B stand, workshop, dock, generator shack, incinerator, kitchen, snowmobile shack, and the fire station by the tents. There are other spill-response materials, including tarps, and additional absorbent sheets, socks and booms, located in absorbent storage on site. The locations of these materials varies as required by operations at the site. A detailed inventory of spill kit contents and additional spill- response equipment is included in Appendix 5. Regular inventory updates are provided in list form to all team members. Spill Report forms are included in Appendix 6.


7.0 TRAINING AND PRACTICE DRILLS 7.1 Training

All members of the Response Team for the 2004 Exploration Programme with the exception of the environmental consultant advisers -- will be familiar with the spill response resources at Kennady Lake/Gahcho Kué camp (including their location and how to access them), this Contingency Plan and appropriate spill response methods. Involvement of other employees may be required, from time to time e.g., those designated to handle fuels.

This familiarity will be acquired through:

1. Initial or refresher training, as appropriate, provided once per field season. 2. Regular inventory updates are provided in list form to all team members.

Information to be reported includes listing of all resources, number of items, their location, condition, date of last inspection and any special comments (such as expiry dates, under whose authority they may be accessed and special handling instructions).

7.2 Practice Drills

DBCE is aware that without practice, no Contingency Plan has value.

At least one practice drill will be held during each exploration season to give personnel a chance to practice emergency response skills. Each practice will be evaluated and a report prepared with the objective of learning where gaps and deficiencies (either in skills or physical resources) exist, and in what areas more practice is required.

11

Let’s think about howDe Beers minimises its

effects on theenvironment….

12

Fuel Consumption(Aircraft, Vehicles, Generators)

Actions• No idling trucks in the warmer months• Plan trips so travel time is minimised• Proper use of tent stoves and fuelConsequences• Creates air pollution• Company pays high fuel costs

13

Fuel, Oil and Chemical Spillsand Leaks

Actions• Keep spill kits / oil absorbent materials at all drilling

sites and fuel points• Have spill-response procedures, contingency plans (We

now have SPILL PLANS for all camps)• Follow refuelling procedures

Consequences• Spills and leaks pollute the land and water• High clean-up costs

14

Water Use in Camps

Actions• Minimise water use in camps

Consequences• Excessive use means more waste water• Higher probability of runoff problems

15

Water Pollution from Spills andDrilling Fluid Loss

Actions• Minimise water use• Use shut-off valves when not using water lines or

fuel lines

Consequences• Water siltation and spills may harm aquatic life

16

Water Pollution fromSewage Discharge

Actions• Provide washroom facilities that meet regulations

– Construct facilities at least 30m from water

• Maintain sewage systems properly– Monitor wastewater if required

Consequences• Biological pollution affects health of humans and

animals that drink the water

17

Dust & Noise Emissions (fromRoad Construction and Maintenance, Ore

Handling & Blasting)Actions• Consider presence of wildlife and times of greater

sensitivity to noise (e.g. calving)

Consequences• Disturbance of wildlife or land-users

18

Disturbance to land duringsampling

Actions• Avoid “sensitive sites”• Follow any permitting requirements• Avoid disturbing wildlife• Avoid sedimentation in streams• Restore site after sample completedConsequences• Stream siltation• Wildlife disturbance

19

Excavations, Test Pitting andTrenching

Actions• Obtain and follow any required permits• Avoid erosion of dug material into streams• Provide protective fencing• Restore landscape after project completedConsequences• Stream siltation• Wildlife / human entrapment

20

Vegetation Damage(from vehicle operation, clearing helicopter

landing pads, and road and campconstruction)

Actions• Restore sites after project done• Keep to designated routes. No overland shortcuts!• Control drainage from acid-generating rocks• Special care in permafrost areasConsequences• Long-lasting damage to local vegetation

21

Appendix 3 On – Ice Drilling Plan

Appendix 3 Page 1

On-Ice Drilling Plan – April 2003-April 2004

I. INTRODUCTION The purpose of the De Beers Canada Exploration (DBCE) Plan for Drilling on Ice is to provide information such that the conduct of drilling operations is in consonance with the DBCE Environmental Management System (EMS) and De Beers Canada Policies (cf. Introduction-Contingency Plan, and Appendices 1a, 1b and 1c), all of which support the corporate commitment to regulatory compliance. The Plan for Drilling on Ice outlines the general guidelines for diamond-drill hole (DDH) exploration and geotechnical drilling, which separate activities may be conducted in winter-spring 2004 on the Kennady Lake/Gahcho Kué property. If the geotechnical programme is conducted – commencing with camp occupation in December 2003 or January 2004 and concluding in April 2004 – the winter-access route to Gahcho Kué (cf. Spill Plan Figure 6) may be re-established, and the programme would be timed to allow use of the main Lupin Winter Road. If an exploration drill programme only is conducted, no winter-access route is likely, and the drill programme likely would occur between February and March 2004. In the event that both programmes should proceed, it is probable that the exploration programme would follow the geotechnical programme, i.e., occurring in April-May 2004. The Plan will be in effect during the 2004 winter season and future seasons where standard small- or large-diameter core drilling may occur on ice; should further large-diameter (LDDH) reverse-circulation drilling be planned in future (e.g., in 2005 or 2006), the Plan will be updated accordingly. As Major Drilling Group (regional office in Yellowknife) has one wireline core drill on site (Boyles 25A), it can be expected that Major would carry out the exploration drilling; a copy of Major’s Environmental Policy is attached as Figure A3-8. The geotechnical drilling may be carried out by Boart Longyear (of Saskatoon and North Bay, ON), and thus technical data on two types of drill rigs which might be deployed – the LF-70 and LY-50 – is included in Appendix 11 of the Project Description; technical data on the Boyles 17A/Boyles 25A also can be found in Appendix 11. No evaluation or LDDH drilling for exaction of a surface bulk sample is contemplated in 2004. Nevertheless, the coring and production methodology used in the Phase IV evaluation programme in 2002 is included below (Section III), as any future evaluation is not expected to deviate appreciably from that used in Phase IV. (It should be assumed that future on-ice LDDH drilling would be by means of reverse-flood air-assist technology). The general project and regional areas are shown in Figures 1 and 2. The Plan has been developed to comply with the Company's commitment to proactive co-operation with regulatory authorities, and to keep federal and territorial regulators informed of planned activities and the equipment that will be used to carry them out.

Appendix 3 Page 2 On-Ice Drilling Plan – April 2003-April 2004

II. PROGRAMME OVERVIEW II-A. PURPOSE OF CURRENT PROGRAMME

The work which may be undertaken is identified as the "Kennady Lake/Gahcho Kué Exploration Programmes for 2004." These two separate programmes (discussed on Page 1) are now at the planning stage.

The objective of the exploration drill programme is to conduct initial and/or followup DDH drilling of selected targets, most probably in the Kelvin-Faraday Lakes area northeast of Kennady Lake (Spill Plan - Figure 1). If kimberlite is intersected, one or more additional holes may be drilled to gain information on the occurrence and contacts. The objective of the geotechnical drill programme is to gain site information on the Gahcho Kué camp peninsula and environs, principally over and around the Hearne, 5034 and Tuzo kimberlites under Kennady Lake, and on adjacent land areas, covering in total some 50 km2. The potential geotechnical drill programme, as of October 2002, includes packer test holes, both lake and land-based, as well as geotechnical core holes and thermistor holes. A majority of holes likely would be land-based. Up to three drill rigs might be required: potentially one Boart Longyear LY-50, one “Geobor S” geotechnical drill, and one CME-75; the CME-75 is similar to Boart’s LF-70 hydraulic core drill (Appendix 11 –Project Description) in capability and size, except that it is track-mounted and rigged with an auger for geotechnical drilling applications).

II-B. RESPONSIBLE WATER USE IN THE PROGRAMME In line with DBCE’s commitment to its Environmental Policy (Appendix 1b), DBCE

intends to control freshwater use and temporary water turbidity by means of standard closed-loop drilling (Figure A3-1 shows DDH core drilling wherein return produced reports to a Poly-Drill tank, which separates out solids before returning water to the system. Typically, return is pumped directly to a designated land-based natural sump or to a mud tank right at drill-side, whose contents are then pumped to a sump. Where feasible, (i.e., when exploration drilling occurs close to a trail leading to camp), the mud tank with its contents is moved by the on-site loader to the Cuttings Containment Facility (Spill Plan – Figure 3), where contents are discharged to the Facility.

In a reverse-flood air-assist LDDH system, such as deployed in Phases III and IV for

bulk sampling of the Hearne and 5034 kimberlite bodies, compressed air introduced into the drill string (i.e., air-assist) is the mechanism used to move drill cuttings gently from the face of the drill bit to surface. The desilted underflow is then recycled by gravity-feed back down the hole (i.e., “reverse-flood” (Figure A3-2) for continuance of drilling.) Relict drillwater and lights report to the Cuttings Containment Facility via vacuum truck and orebags.


II-C. SCHEDULE OF POTENTIAL DRILL PROGRAMME ACTIVITIES

(Schedule supposes that both the geotechnical drill programme and exploration drill programme proceed in 2004. As noted on Page 1, however, it is unknown at this time whether both programmes would proceed next year).

1. December 2003 or January 2004: Reopen camp in this period, if

geotechnical programme is to occur. Clear icestrip. Thicken ice for landing of cargo aircraft, if necessary. Build/plough snow routes and ramps from lake to shore, and camp.

2. January or February 2004: Obtain new Quarry Permit, and haul aggregate

from North Esker (Figure 5) to replenish camp stockpile; a proportion of the pile (at least 50m3) always is reserved, in case of the need for emergency response/repairs.

3. February 2004: Construct spur off Lupin Winter Road to Gahcho Kué

camp, if geotechnical programme proceeds. Bring in fuel, support equipment and drill rigs. (If geotechnical programme does not proceed, exploration programme would commence here and conclude at the end of March; no winter-route would be used.)

4. February through April 2004: Conduct geotechnical drilling (some ice-based,

some land-based); cleanup of each drillsite immediately after use, and before moving to the next site. Demobilise drills and ancillary equipment via winter-access route. Commence exploration drill programme with core drill already on site. Winter water-quality sampling would occur before, during and after drilling, as in past seasons.

5. May 2004: Conclusion of exploration drill programme; clean up camp and

environs, demobilise personnel and shut down camp.

Summer 2004: Land-based geotechnical drilling may occur, July to September 2004. Exploration drilling of remaining land-based targets (if these exist) may be conducted during the same period, or following the geotechnical programme, if the one core drill on site is shared between programmes; if rig is not shared, one of the geotechnical drills would have been parked on site over the spring. Complete camp maintenance and cleanup, decanting of clean water from the Cuttings Containment Facility, and continuation of environmental baseline programmes.

II-D. MARKING AND CLEANUP OF SITES

Drillsites will be marked with flags and pickets prior to drilling. Ice berms also will be built for potential containment. Driving the casing invariably is a messy but benign operation.


Wet sediments occasionally may spill over the casing onto the ice surrounding the drills. Dribblings of fuel and oil from the drills also may collect on the ice, as well, despite the precaution of drip pans under stationary equipment and drip pails for refuelling, but such drips easily are absorbed by snow and, if required, by ultra-dry commercial absorbent or pads. A spill kit and additional absorbents are present at each drillsite. Scraping and shovelling by means of the on-site loader and hand shovels, combined with steaming, if required, effectively remove such material, and the scrapings are transported to a designated land-based sump on shore. After drilling, and prior to programme conclusion, final debris, such as wood lathe and timbers which may have frozen in place, will be removed to camp by helicopter or loader, for recycling or incineration.

III. BULK-SAMPLING (Not Planned for 2004) III-A. REVERSE-CIRCULATION LDDH DRILLING

Casing: The drilling method used at LDDH casing operations in 2002 at Gahcho Kué can be described as a “pressurised air-hammer reverse-circulation” method. The principle of this particular reverse-circulation (RC) drilling method is that drilled material is recovered up to surface from hole bottom inside the drill pipe, with the drill medium (in this case, compressed air) being circulated down the hole along the outer wall of the dual-wall drill pipe used. A cap seals the top of the casing and keeps the hole air-tight and pressurised, with all drilled material and water being brought up to surface. Thus, as the hole is being cased, the cased portion is free of drill chips and water. Drilled material and recovered water is not circulated back down the hole. Production: The production drilling method employed is referred to as “reverse-flood air-assist”; it is a closed-loop RC method. The basic procedure is as follows: At hole bottom, the kimberlite is broken down by the action of a large tricone drill bit into rock chips and finer grains; these cuttings are returned to surface inside the drill string A top-drive/table-drive drill rig, customised for 61cm (24in) reverse-flood air-assist RC bulk sampling, was deployed during Phase III in 2001 and Phase IV in 2002 to recover kimberlite chip sample of approximately 50t per hole from a vertical depth of up to 300m (Figure A3-2). (Also see Figure 3b – Project Description, showing equipment weights for the TH-150 drill and ancillary equipment.) In this system, after the casing is driven by a separate drill, the RC production rig is moved over the drillhole and rock fragments broken up by the rotary drill bit are then borne by water, and propelled by compressed air, to surface.

The recovered material is depressurised through a sample dropout box onto a “shaker table” or vibrating screen deck equipped with 1.6mm (nominal) mesh. The kimberlite chips are washed using recycled water as they vibrate across this screen (Figures A3-3), and the underflow solids or fines are thus removed. The drill fluid (water) is then returned back down the hole for reuse. Closed-loop circulation is maintained and is kept balanced at all times.


The recovered material is collected as it falls off the vibrating shaker-table screen down a chute and into 1-tonne sample bags positioned underneath the chute. The full sample bags are removed by a loader and can be transported off-site by heavy-haul trucks or aircraft to an off-site processing facility.

The -1.6mm material (i.e., the underflow ”fines” material that is small enough to pass through the mesh screen on the shaker table) is collected in a baffled settling tank under the shaker table. The water and fines in this tank are then pumped through a desilting cyclone, where the silt fraction is removed. The removed material is conveyed by a vacuum truck to the Cuttings Containment Facility on land. The above-noted process of casing and bulk-sample recovery will be used again in future evaluation programmes (i.e., beyond 2004).

Note: Figures A3-2 and A3-3 were adapted from Layne Christensen Canada Limited’s Large Diameter Kimberlite Bulk Sample proposal of 2001.

IV. GROUTING IV-A. CEMENTING AS STANDARD PROCEDURE

After drilling of either a DDH or LDDH hole is complete and casing pulled and/or cut, the hole is plugged (i.e., sealed) with grouting cement (typically, a mixture of cement and bentonite); depending on conditions, small-diameter holes may be grouted all the way to bottom; large-diameter holes are grouted to a depth of 10m into kimberlite. Cement is mixed in a heated shack at drillside. Grouting is expected to provide improved ground stability and safety from water inflooding, should underground work proceed in future.

V. WORKING ON ICE V-A. ICE PADS (Built for bulk-sampling)

Although typically not constructed for small-diameter core drilling in winter, ice pads are constructed for large-diameter core (LDC) rigs deployed for delineation and LDDH casing and production rigs deployed for evaluation. To accommodate the mass of such drills and their ancillary equipment (over 30 000kg per piece), engineers design suitable weight-bearing pads and build them by flooding lakewater onto the ice surface. In Phases II and IVI, the pads used for drilling on Kennady Lake were flooded for a nearly two-month period. Typically heavy core rigs (about 27 700kg) require ice thickness of 1 600mm as a minimum. (A 1998 Kennady winter temperature chart is attached as Figure A3-4).

Appendix 3 Page 6

On-Ice Drilling Plan – April 2003-April 2004

Ice trails built to allow access of equipment to and from drillsites are regularly checked for competency, groomed and cleared of excess snow. No fuel or other contaminants are stored on these temporary trails. Each is inspected and cleaned up, if necessary, prior to abandonment. (A winter-access trail was constructed between Kennady Lake and Kelvin-Faraday Lakes for winter 2003 exploration drilling (Projection Description – Map 11). The accompanying table (Figure A3-7) is a general guide to the thickness of ice that is required to support the weight of various moving and stationary equipment loads (specifics on several drill rigs are found in the Project Description –Appendix 11).

VI-B. ON-ICE AIRSTRIPS

To accommodate the weight of loaded aircraft in early winter, the area designated as the Kennady Lake/Gahcho Kué icestrip (Figure 14) must be cleared of snow upon camp occupancy in early winter to hasten natural ice thickening for landing of a Twin Otter on skiis and wheels. An additional icestrip may be constructed south of the Twin strip to accommodate DC-3 and Skyvan freight wheeled aircraft. Only if necessary would a Hercules aircraft strip be constructed; this is an engineered strip designed to site-specific conditions and constructed to air carrier specifications, and requires controlled flooding of the lake surface to increase ice thickness to the minimum effective weight.

Figure A3-5 which follows is the Transport Canada Standard table for loading on freshwater ice, which shows various typical aircraft weights, presented in lbs./kgs. as well as in kN, and the minimum required ice thickness for each of those weights.

The on-ice airstrip(s) will be kept free of debris and regularly checked for competency, fuel-handling practices, and kept groomed. No fuel or other contaminants will be stored on ice, and drums will be removed promptly when offloaded from aircraft. The icestrip area will be inspected and cleaned prior to spring breakup. (An on-ice airstrip validation report from Sandwell Engineering, constructors of the 2002 Hercules icestrip, is attached in Appendix 4).

Don’t get stuck! Independent rotary drives

conquer a variety of overburden conditions

oremost’s patented Dual Rotary(originally “Barber”) drills havebeen working around the globe for

almost 20 years. In that time, the DR methodhas gained the reputation for exceptional per-formance in unconsolidated overburden.

DR rigs feature a lower rotary drive that canadvance casing up to 40 inches (1m) in diam-eter through unconsolidated overburden likesand, gravel and boulders. Pulldown, pullbackand rotational forces are effectively transmittedto the casing via power-operated jaws.

An independent rotary top drive simulta-neously handles a drillstring equipped with adown-the-hole hammer, drag bit or rollingcone rock bit. Because the drives are inde-pendent, the bit can drill inside, flush with orahead of the casing.

In heaving situations, or in situationswhere sample accuracy is important, the casingis advanced ahead of the drill bit for greaterhole stability and minimal cross-contamina-tion of cuttings.

In situations where boulders are encoun-tered, the operator can stop the casing rotation,and continue through the boulder with thedrill string. Once a pilot hole is established inthe boulder, the operator begins rotating thecasing again, and it follows the drill stringthrough the boulder. This “pilot hole” tech-nique combines with the rotation of the casingto deliver an uncommonly straight borehole.

Once the desired casing depth has beenachieved, the DR continues drilling like a con-ventional top-drive air drill.

DR-12The DR-12 is a light, yet powerful PTO rig

designed for waterwell contractors drilling inmoderate to severe overburden conditions. Itwill handle casing up to 12" (0.3m) in diameter,and will set a typical 6" (0.15m) casing to over300' (100m). The DR-12 has additional appli-cations in placer sampling, environmentaldrilling and cathodic protection.

DR-24The DR-24 will set casing up to 24"

(0.61m) in diameter. This rig is commonlyused for municipal wells,construction founda-tion and piling work, and holes for hydraulicelevator jacks. The DR-24 is available in PTOand deck engine configurations and can bemounted on a truck, trailer or self-propelledtrack carrier.

DR-40Foremost’s largest DR model, is capable of

handling casing up to 40" (1m) in diameter.The DR-40 excels in large diameter construc-tion and municipal waterwell drilling.Standard equipment includes a Cummins600HP deck engine and Sullair 1150/350compressor.

Though actual diameter of casing could vary, a similar air-assist system could be used for bulk sampling of a lake-based kimberlite on the AK property in future years.

This modification to standard reverse-circulation (RC) drilling technology calls for injection of air into the closed-loop system to lift water-borne chip sample to surface for recovery more gently than water alone – thus decreasing likelihood

January 06 2002 File: 142441 Layne Christensen Canada Limited 1345 Highfield Crescent SE Calgary, AB T2G 5N2 Attention: Mr. Colin Kinley Mr. Brian Gibbs Gentlemen: Reference: Kennady Lake (Gacho Kue) Herc Ice Strip Certification Winter Season 2001/ 2002 Operation This letter documents the design, construction and recommendations for the use of a Herc ice strip at the De Beers Canada Exploration Inc. Kennady Lake site, during the winter season of 2001/2002. Figure 1 depicts the layout of the herc strip at the Kennady Lake site. The centre line station listed as a metre unit is consistent with the herc strip layout of previous years. This is to say that the herc strip 0+00 station UTM position during the 2001/2002 winter season corresponds to the herc strip UTM versus station designation employed in January 1999 .

1.0 Design

Sandwell Engineering Inc. employed the following reference and standards for the winter season 2001/2002 Kennady Lake Herc ice strip certification. 1. “Recommended Minimum Ice Thickness for Limited Aircraft Operations”, Transport

Canada, Airport Facilities, AK-68-14-001, 1974 2. First Air requirements for Herc operations 3. “Review of Floating Ice Aircraft Landing Strip Specifications” for National Research

Council NRC 991-114915309, Sandwell 1992


Thickness Requirements The design ice thickness at centre line for the herc strip at Kennady Lake for the 30 inch natural ice and 30 inch buildup ice combination is 60 inch. Away from centre line the design ice thickness is 55 inch. The 55 inch requirement will also include the tarmac area. Table 2 illustrates that the Herc ice strip as-built ice thickness at centre line and away from centre line meet the 60/55 inch requirement. The standard ice thickness for herc operations on natural ice is given as 48 inch from reference 1 above. The borehole jack test results summarized in Table 2 illustrates that there is little difference between the natural ice strength versus builtup ice strength at the Kennady Lake site over the 2001/2002 winter season. First Air required a minimum operation thickness of 50 inch for the Kennady Lake herc strip therefore the Sandwell requirement will give an added degree of safety relative to the First Air requirement. The increased thickness relative to the 48 inch standard will compensate for the 50% flexural stress increase expected due to the shallow water and proximity to shore factors. The 60/55 inch thickness requirement will err on the side of safety. It should be noted that the shallow water depth and very close proximity to shore of this herc strip location make the 60/55 inch thickness requirement necessary. At both ends of the strip, land is within 100 ft (30m) of the strip edge and a shoal at the 0+700 m station on the north side of the strip is also within 100 ft of the strip edge. Speeds on the tarmac will be slow and for this reason the 55 inch thickness requirement will be applied to this area. Strip Dimension First Air required a minimum strip length of 1524m (5,000 ft) at a minimum width of 46m (150 ft). The barrel strip markers at the Kennady Lake Herc strip were set at the 49m (160 ft) width on an interval of approximately 200 ft for a total length of 1538m (5050 ft.) as illustrated in Figure 2. Ice Strength Parameter Table 2 presents a summary of the borehole ice compression strengths measured at the Kennady Lake herc strip on January 05 2002. The tensile strength of ice is usually taken as 1/9 of the confined borehole compressive strength test value. Since both natural and built-up ice categories exhibited similar confined compressive strength value of approximately 20 MPa, an ice tensile strength of 2200 kPa is indicated. Reference 3 of the source reference material indicates that the induced ice flexural stress level for a Herc operating on a 1.22m (48 in) ice sheet is in the order of 700 kPa. This would indicate a factor of safety of three against first crack failure, due to the operation of a Herc aircraft on an ice sheet. Reference 3 of this report requires 12 MPa minimum borehole ice compression strength for herc ice strip operation. The 20 Mpa strength levels indicated for both the natural and built-up ice for the Kennady Lake herc ice strip is at a safe ice strength level.


Ice Temperature Parameter The Transport Canada reference 1 noted above for fresh water ice strips requires an ice temperature colder than minus 1°C for limited aircraft operation. The ice temperatures at the winter 2001/2002 Kennady Lake Herc ice strip as given in Table 3 are well within the safe zone for herc operation.

3.0 Conclusions and Recommendations

The winter 2001/2002 Herc strip at Kennady Lake was constructed to design specifications December 13, 2001 to January 02, 2002. The as-built Kennady Lake herc ice strip as of January 02, 2002 meets the design specifications required by this report and is validated as such. Ice strength and performance varies with temperature and time during a season of operation. Thus measured parameters on January 02, 2002 may have limit bearing on performance after prolonged periods of warm weather with above freezing temperatures and sunlight. This condition eventually leads to loss of latent heat and substantially


weakened ice. In part, responsibility for the safe operation of the Herc strip at a later date must rest with the field staff who will monitor the performance of the ice strip on the date of use. Sandwell will be present during the herc takeoff and landing period at the Kennady Lake site to ensure that the ice strip performance parameters required by this document are met or exceeded. Thank you for the challenge of providing engineering services on this project. Yours truly, Sandwell Engineering Inc.
