GOLD RESOURCE: Hammond Reef hosts over 10 million oz

ONTARIO - Osisko Mining Corp. of Montreal says its 100% owned Hammond Reef project near Atikokan contains perhaps 10.52 million oz of gold. It is early days for the project, so resources are in the inferred category: 530.6 million tonnes grading 0.62 g/t Au, using a 0.30 g/t cut-off.

The in pit inferred resource is 336.58 million tonnes at 0.63 g/t Au or 6.86 million oz using a gold price of US$1,200/oz. This is an increase of 25% or 1.36 million oz over the 2009 estimate made by then-owner Brett Resources.

If the gold price were US$1,000/oz, the inferred pit resource would be 243.40 million tonnes grading 0.72 g/t or 5.32 million oz of gold, according to Osisko. And should the gold price rise and stay at US$1,800/oz, the inferred pit resource would be 658.23 million tonnes at 0.51 g/t Au or 10.79 million oz of gold.

Sean Roosen, Osisko president and CEO, commented, "While there is no doubt that the resource has a lower overall grade than Canadian Malartic, an important point to note is that the new in pit resource for Hammond Reef has a low strip ratio of 1.25 and is quite robust, as it is based on current processing and mining costs at Canadian Malartic, adjusted for higher electrical costs in Ontario."
