New results from the drill program at the Detour Lake gold project in northeastern Ontario show mineralization continuing between two proposed open pits and new mineralization within one of the pits.
Detour Gold (DGC-T, DRGDF-O) has now finished the first, 50,000-metre phase of its exploration program on the project. The new holes tested previously undrilled parts of the West Pit and targets along the Sunday Lake shear, in the area now known as the Gap Zone.
Drill holes in the proposed West Pit, where an indicated resource of 20 million tonnes grading 2.1 grams gold per tonne, and an inferred resource of 31 million tonnes grading 1.8 grams has already been defined, mainly intersected intervals of 5 to 15 metres, but with a large number of wider intersections. Among the better results were a 44.9-metre intersection running 2.2 grams gold per tonne and a 29-metre intersection grading 3 grams gold.
Along the Gap Zone, running between the West Pit and another proposed pit on the Calcite Zone, mineralized intervals were mostly 5 to 7 metres in core length, with gold grades typically between 1 and 2 grams per tonne. Wider and higher-grade intersections included a 23-metre interval grading 2 grams per tonne and a 19-metre interval grading 5.6 grams.
Meanwhile, Trade Winds Ventures (TWD-V, TWDIF-O) has received more results from its winter drill program on the M Zone mineralization, west of the Detour targets. The M zone crosses the property line between Detour Gold’s wholly-owned ground and the Block A property, where Trade Winds is operator in an equal joint venture with Detour.
Four holes all intersected multiple intervals of gold mineralization on the M Zone structure, about 1 km to the northwest and running roughly parallel to the Sunday Lake shear. Hole TWDDH-194 was probably the most successful, cutting an 8-metre length grading 6.7 grams gold per tonne and a 4.8-metre length grading 2.24 grams per tonne. A second hole, TWDDH-191, cut 5.3 metres grading 3.8 grams at a 73-metre vertical depth, then, at 266 metres vertical, cut another metre grading 8.7 grams per tonne.
Two other holes intersected gold mineralization over 0.5 metre to 3 metres in core length, with gold grades of 2.3 to 4.5 grams per tonne, plus one 0.5-metre intersection in the M Zone hangingwall that ran 107.5 grams gold per tonne.
A resource calculation in October 2006 estimated the Block A indicated resource at 14.2 million tonnes grading 1.8 grams gold per tonne, and its inferred resource at 24.8 million tonnes grading 1.9 grams.
About 60 km southwest, Lake Shore Gold (LSG-T, LSGGF-O) has started a 3,000-metre drill program on its property in Blakelock Twp., along strike from the Casa Berardi gold deposit in western Quebec. Lake Shore’s targets include conductors detected in airborne geophysical surveys, areas where overburden sampling detected gold grains in till, and stepouts from earlier drill intersections.
Lake Shore has also increased its land position in the area, to the west, in McQuibban and Sangster Twps. The two new properties cover about 52 sq. km.
