Discovery 1 was a planned 3,000m to 3,500m deep drill hole, designed to target two down-plunge extensions of known gold zones and investigate the projected source area of the Windfall deposit at depth. The working model for the Windfall deposit interprets an outer shell and centre of a possible porphyry intrusion feeding the Windfall-Lynx gold system.

The final length of Discovery 1 was 3,467m becoming the longest diamond drill hole in Canada, and achieving a vertical depth of 2,700m from the surface. The hole was drilled from the surface to 3,149m with NQ rods and finished with BQ rods.

Over the years, the Major Drilling has positioned itself as one of the largest specialised drilling operators in the world, by leveraging its skilled personnel, specialised equipment and robust safety systems.

"It is an honour to have been a part of this monumental project," Major Drilling president and CEO, Denis Larocque said. "We are proud of the hard work and expertise that our team has contributed along with Osisko Mining to reach this historic milestone in Canadian drilling."

Osisko president and CEO, John Burzynski, added: "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. These results of the Discovery 1 hole show that the Windfall system is extensive with substantial room for potential growth."
