Osisko Mining Inc. (TSX:OSK) has reported results from the longest diamond drill mining exploration hole in Canada. The hole, called Discovery-1, was drilled at Osisko’s Windfall deposit in Northweastern Quebec, north of Val d’Or.

The hole was planned as a 3,000 to 3,500 foot exploration drill hole, designed to target known gold zones in the Windfall deposit and to investigate the projected source of Windfall at depth, said the company.

The final length of Discovery-1 was 3467 metres, becoming the longest diamond drill hole in Canada, and achieving a vertical depth of 2700 metres from surface, said the company. The drilling was carried out by Major Drilling Group International, a Canadian company with worldwide contracts.

Among some of the results were intersection of 96 metres at 1.05 grams per tonne (GPT), two metres at 10.7 gpt and four metres of 5.25 gpt, said the company release.

Osisko President and Chief Executive Officer John Burzynski commented on the achievement:

“Discovery-1 is a great success and achievement. We are very proud of our Osisko team and Major Drilling for their tremendous work completing this hole. Successes include the discovery of the Underdog and Triple 8 extensions, the wide intercepts of anomalous gold values similar to those observed in the Lynx system, and now these new high value gold intercepts at depth. These results of the Discovery-1 hole show that the Windfall system is extensive with substantial room for potential growth.”
