A new resource calculation for Vior Mining Exploration (VIO-V) has doubled the size of the Douay gold deposit, about 60 km south of Matagami, Que.
Vior’s consulting firm, Geostat, based its calculations on a larger low-grade mining concept and a smaller high-grade concept. In the low-grade scenario, there is a measured and indicated resource of 2.9 million tonnes grading 2.9 grams gold per tonne, plus 44.9 million tonnes inferred at an average 1.3 grams per tonne. The cutoff grade for the calculation was 0.7 gram gold per tonne.
A high-grade calculation, using a cutoff grade of 3 grams gold per tonne, leads to a measured and indicated resource of 971,000 tonnes grading 5.6 grams gold per tonne, and an inferred resource of 1.6 million tonnes at 3.9 grams per tonne.
Much of the indicated resource is on Douay West, where an estimate in 2005 showed 515,000 tonnes indicated at 5.9 grams gold per tonne and 529,000 tonnes inferred at 5.4 grams per tonne.
Apart from Douay West, the Douay deposit consists of seven mineralized zones: Zone 531, Zone 10, Zone 20, the Main Zone, the Adam Porphyry, the 92-7 Porphyry, and the Central Porphyry. A previous inferred resource estimate showed Adam with 7.1 million tonnes grading 1.1 gram per tonne, 92-7 with 5.8 million tonnes grading 0.7 gram per tonne, and the Central Porphyry with 4.4 million tonnes grading 0.8 gram per tonne. The other zones were smaller, but higher-grade.
