Mountain Province

The Kennady Lake project is the largest new diamond mine under development globally, and has the potential to become one of Canada's major high grade and long-life diamond mines.

The Kennady Lake diamond project is located on federal land in Canada's Northwest Territories and is held by the Kennady Lake Joint Venture under renewable 21 year leases. The project is on a 74,128 acre site located at Kennady Lake, approximately 300 kilometres northeast of Yellowknife and 90 kilometres east of De Beers' Snap Lake diamond mine.

Kennady Lake falls under the AK group of renewable 21-year mining leases and mineral claims. This is currently the best mining contract in the industry. Most other mineral claim contracts are now being converted into 21-year mining leases.

In the early 1990's Kennady Lake was staked by Mountain Province Diamonds. Canamera Geological Ltd. was contracted to conduct the original exploration which led to the discovery of the 5034 kimberlite pipe in January 1995.

1997	Letter agreement entered into with Monopros Limited (now De Beers Canada) in terms of which they could earn a 51% interest in the project. Hearne, Tuzo and Telsa pipes discovered in mid-1997.
1998	Mini bulk sampling of 5034, Hearne, Tuzo and Telsa by Monopros. Preliminary scoping study by MRDI (now AMEC).
1999	Bulk sampling by large diameter drilling of Hearne, Tuzo and Telsa by Monopros.
2000	De Beers Canada conducts Desktop Study.
2001	Further resource drilling of 5034, Hearne and Tuzo by De Beers Canada.
2002	Joint Venture agreement entered into between Mountain Province (44.1%), De Beers Canada (51%) and Camphor Ventures (4.9%).
2003	Technical (pre-feasibility) Study commences.
2004/5	Further hydrological, geotechnical design and resource drilling. Engineering and environmental baseline studies completed.
2005	Completion of the C$25 million Technical Study. Commencement of the C$38.5 million advanced exploration program and filing of applications for construction and operating permits.
2006	Mountain Province acquires controlling interest in Camphor Ventures. Independent valuation of Kennady Lake diamonds completed. Tuzo and 5034 North Lobe delineation and geotechnical drilling completed.
2007	Mountain Province acquires 100% of Camphor Ventures thereby increasing interest in Kennady Lake to 49%. Core drilling program completed at Tuzo to upgrade the Tuzo resource. Infill drilling program completed at the 5034 kimberlite. 5034 North Lobe bulk sampling program completed.
2008	Tuzo bulk sampling program completed. 25.14 carat gem quality diamond recovered from Tuzo drill program. Updated independent valuation completed: actual price per carat increases 63% to $135 per carat.
2009	Updated mineral resource statement completed. Revised and restated joint venture agreement concluded between Mountain Province and De Beers. Independent feasibility study commences.
2010	Independent 43-101 feasibility study completed. Mineral reserve declared. Environmental impact assessment filed.
2011	Updated independent diamond valuation completed ($185/carat). Feasibility study approved by JV partners. Decision to build approved by JV partners.

The Kennady Lake kimberlite cluster is in the southeast slave craton. The area was glaciated repeatedly during the Pleistocene, most recently by the Laurentide ice sheet. The Laurentide ice sheet began to recede about 18,000 years ago and the ice retreated past the Kennady Lake project area between 9,000 and 9,500 years ago. Four main pipes comprise the Kennady Lake kimberlite cluster - 5034, Hearne, Tuzo and Telsa. The 5034 kimberlite is an irregular hypabyssal root zone. Hearne and Tesla are transitional diatremes and root zones. Tuzo is the deeper part of a diatremes zone. At present, Telsa is not included in the Kennady Lake mineable resource because of its smaller size (0.4 ha) . However, it may be exploited towards the end of the project life. The shapes and internal geology of each of the kimberlite pipes has been based on the logging of the available drill core. The external shapes and internal geology of each body was modeled in three dimensions using GEMCOM. Both internal and external models were updated after each subsequent drilling program in 2001, 2002, 2004, 2005, 2007 and 2008. All the pipes remain open to depth.
