Osisko made the Golden Bear discovery in June. The D1 discovery hole returned 6.7 metres grading 27.4 g/t gold from OSK-UB-21-232.
The new drill results have traced the D1 zone 170 metres along strike with a plunge to the east-northeast. Drill hole ODK-UB-21-273 returned 2 metres grading 67.1 g/t gold. Two other holes returned 2 metres at 14.9 g/t gold (OSK-UB-21-264) and 2.2 metres at 26.53 g/t gold (OSK-UB-21-272).
At the D2 zone, drilling returned 2 metres grading 62.15 g/t gold in hole OSK-UB-21-261.
The D3 zone is defined by one assay from hole OSK-UB-21-276: 2.2 metres grading 38.67 g/t gold. Assay results are pending from a second hole stepped out 250 metres east of the first hole.
Osisko says the Golden Bear is a “blind” discovery in a geological setting similar to Windfall. That deposit has an alteration and mineralized footprint of over a 4-km strike length and to a vertical extent of 3 km.
The Windfall preliminary economic assessment updated in April covered the Lynx, Underdog, Main and Triple 8 zones. The Lynx zone has a measured resource of 521,000 tonnes grading 11.3 g/t gold for 189,000 contained ounces. The indicated resource includes the Underdog and Main zones and is 5.5 million tonnes grading 9.4 g/t gold for 1.7 million contained ounces. The total inferred resource from all four zones is 16.4 million tonnes at 8 g/t gold for 4.2 million contained ounces.
