Vancouver — Detour Lake is showing promise for Detour Gold (DGC-T, DRGDF-O) and its joint- venture partner for part of the gold project, Trade Winds Ventures (TWD-V, TWDIF-O), as both companies release strong drill results from different areas of the site, in northeastern Ontario.
Detour Gold announced results from 15 new holes from its first-phase program designed to infill drill the known West Pit and Calcite Zone deposits as well as test the continuity of mineralization between the two targets. Results show the gap between the targets is mineralized: hole 32 hit 40 metres grading 1.03 grams gold per tonne starting 69 metres down-hole, hole 54 returned 6.99 grams gold over 12 metres from 191 metres depth, and hole 61 intersected 6 metres of 31.18 grams gold, also starting from 191 metres.
The infill drilling also gave good results. Hole 43, collared in the West Pit, first hit 32 metres of 1.23 grams gold starting 126 metres down-hole, and then 5 metres of 8.29 grams gold starting at 466 metres. Another West Pit hole, no. 46, returned 8.01 grams gold over 12 metres from 320 metres depth. And in the Calcite Zone, Hole 47 hit 22 metres of 1.76 grams gold starting 88 metres down-hole, while hole 50 returned 7.13 grams gold over 7 metres from 202 metres depth.
The Detour Lake project sits in the Abitibi Greenstone Belt. The 242-sq.-km project includes the West Pit and Calcite zone deposits, collectively called the Detour Lake deposit, which hosts an indicated resource of 20 million tonnes grading 2.14 grams gold plus an inferred resource of 35.4 million tonnes grading 1.8 grams gold. The deposit lies just south of the former Detour Lake mine, which produced 1.8 million oz. gold between 1983 and 1999 under Placer Dome.
The 2006 resource estimate used a gold price of US$450 per oz. and assumed one large pit exploiting both deposits. The optimization study produced two separate pits. Thus Detour Gold’s 2007 drill programs were designed to assess continuity of mineralization, as well as upgrade inferred resources to indicated. The company plans to release a new resource estimate in the fall.
Some 5 km to the northwest of the Detour Lake deposit lies Block A, a separate target on the same property being explored through a JV with Trade Winds Ventures. Trade Winds is also pulling strong, though short, gold cores as the company steps out to the west from the M Zone corridor discovered last summer.
Hole 219 returned 5.78 grams gold over 1 metre at 114 metres depth followed by 4.6 metres of 5.48 grams gold starting 280 metres down-hole. Hole 222 intersected 2 metres grading 8.96 grams gold at 245 metres below surface; 20 metres deeper, the drill hit 0.5 metre of 14.75 grams gold. And hole 224 returned 1.08 grams gold over 7.88 metres starting 166 metres below surface.
Trade Winds’ 2007 drill programs at Block A were designed to better outline the new zone discovered in 2006 and explore west of the new zone. To the east sits a 2006 resource estimate of 14.2 million indicated tonnes grading 1.77 grams gold and 24.8 million inferred tonnes grading 1.88 grams gold.
