QUEBEC – Toronto’s Osisko Mining reports a bonanza – 2,223 g/t gold over 2.0 metres – intersection in zone 27 at its Windfall Lake gold project in the James Bay region, 200 km northeast of Val d’Or. The company began an 800,000-metre drill program in 2015, and is currently focused on infill drilling at the main Windfall and Lynx deposits.
Windfall has had more than its share of bonanza drill results. Here are some of the most recent:
Hole WST-18-0025: 2,223 g/t gold over 2.0 metres;
Hole OSK-W-18-1785: 69.9 g/t over 2.7 metres;
Hole OSK-W-18-1785-W1: 64.2 g/t over 2.1 metres;
Hole OSK-W-18-1797: 12.3 g/t over 10.7 metres;
Hole OSK-W-18-1781: 34.6 g/t over 3.5 metres;
Hole OSK-W-18-1706: 45.5 g/t over 2.6 metres; and
Hole OSK-W-18-1756: 30.5 g/t over 3.5 metres.
Osisko’s most recent resource estimate covers six separate zones. The indicated portion includes 2.9 million tonnes grading 8.17 g/t gold for 754,000 contained oz. The inferred portion comprises 10.4 million tonnes grading 7.11 g/t gold for close to 2.4 million contained oz. of gold.
Preliminary results of a bulk sample made public in December, put the average head grade at 9.7 g/t gold and 4.4 g/t silver. The sample was taken from zone 27.

These are great results, but the continuity of the grades is all important. What is the defining structure of this deposit?
