Four holes were drilled to test zone 157, about 500 metres east of the East mine. The holes were widely spaced, covering a 300-by-200-metre area.
The best intersection graded 10.8 grams per tonne over 5.2 metres, including 0.5 metre of 37.3 grams and 1.2 metres of 27.2 grams. A previously reported hole intersected 20.6 grams gold over 3 metres. One hole intersected 1.3 grams gold over 9 metres.
The zone was intersected at a down-hole depth of 415-437 metres.
Gold is associated with disseminated pyrite and arsenopyrite in stockwork quartz veins crosscutting basalt, south of the Casa Berardi fault.
All holes were drilled through the fault. Grades ranging from 1.1 to 5.4 grams gold over true widths of 1.2-16 metres were intersected at down-hole depths of 550-986 metres.
Similar geology and gold grades have been found 1,000 metres west of the East mine workings. The Section 140 zone, at a depth of about 800 metres, runs along the southern edge of the fault.
Highlighting this zone is an intercept grading 7.8 grams gold per tonne over a 5.3-metre true width, including 2.2 metres of 11.7 grams gold.
A few of the drill holes did not intersect significant gold, but holes were widely spaced.
The East mine operated between 1988 and 1997, during which time it produced 344,200 oz. gold from 1.7 million tonnes grading 6.34 grams per tonne.
