Discovery 1 was a planned 3000 m (9843 ft) to 3500 m (11 483 ft) 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 3467 m (11 375 ft), becoming the longest diamond drill hole in Canada, and achieving a vertical depth of 2700 m (8858 ft) from surface. Analytical results from the final 200 m (656 ft) are at the laboratory. Results are pending. The hole was drilled from surface to 3149 m (10 331 ft) with N-size rods and finished with B-size rods.
Osisko President and Chief Executive Officer, John Burzynski commented: ‘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.’
