Osisko Mining Corporation

• Summary

  Osisko's flagship property is the 100% owned Canadian Malartic gold property, located in the heart of Quebec's prolific Abitibi Gold Belt, immediately south of the town of Malartic, approximately 20 kilometres west of the town Val d'Or. The property (126 claims and one mining concession with a total surface area of 5,655 hectares) now covers an area of 230km²with the addition to the west of the contiguous Amphi and Cadillac properties. Osisko's Malartic properties had underground production from 1935 to 1983 over 5 million ounces of gold from four mines (Canadian Malartic, Barnat, Sladen and East Malartic).

  Osisko acquired a 100% interest in the Canadian Malartic property in November 2004, and initiated a detailed compilation of the extensive historical database in January 2005, including data from over 5,000 surface and underground drill holes. Osisko commenced its drilling program on the property in March 2005 and has drilled over 500,000 metres since then.

  The deposit is an Archean porphyry gold system, consisting of a widespread shell of disseminated gold and pyrite mineralization hosted by diorite porphyry and altered metasediments. Drilling and compilation work has outlined a gold mineralized system measuring 1900 metres x 350 metres, with a variable true thickness ranging from 40 to 270 metres to a vertical depth of 320 metres from surface. The system is open to the west and to the south at depth.

  The project offers potential for a significant near-surface gold deposit, located near existing infrastructure and amenable to open pit, bulk tonnage mining if proven economic.
