Drilling by Osisko Exploration (OSK-V) at the Canadian Malartic property on the southern boundary of Malartic, Que., continues to confirm long low-grade gold intersections.
The newest drill results are from infill holes at the eastern end of the host porphyry intrusion. Previous drilling by both Osisko and earlier operator Lac Minerals established that the host porphyry is about 1.4 km long and about 350 metres wide, with some intersections down to about 200 metres depth.
A preliminary resource estimate is planned for later this year.
Among the better intersections cut in the most recent 15 holes were a 191.3-metre interval averaging 1.5 grams gold per tonne, 166.8 metres grading 1.1 gram per tonne, and 103.6 metres grading 1.4 grams per tonne. Most of the intervals had gold grades between 1 and 2 grams per tonne, and lengths were in the 30-metre to 100-metre range.
Osisko’s drill holes are mainly vertical, as the zone being tested forms an arch-like body over the main porphyry intrusion.
Most surprises in the recent drilling were favourable ones. In hole CM06-742, the mineralized zone was about 50 metres longer than expected, extending 116.8 metres and averaging 1 gram gold per tonne. Similarly, hole CM06-750 encountered 183.3 metres grading 1.1 gram per tonne, an intersection about 65 metres longer than had been modelled from earlier drilling.
