Drill Program Results At Windfall Lake Gold Project

 

TORONTO - Osisko Mining Inc. reported new results from the ongoing drill program at its 100% owned Windfall Lake gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Quebec. The 800,000 meter drill program combines definition, expansion and exploration drilling in and around the main Windfall gold deposit and the adjacent Lynx deposit. Significant new analytical results from 90 intercepts in 52 drill holes focused on infill and expansion drilling in the Lynx deposit. Osisko continues to extend the known Lynx zones of mineralization through the application of the Windfall geological model and as the density of drilling increases.

The main Lynx Corridor has been extended up plunge 250 meters SW from the last drill intercept for a total current strike length of confirmed mineralization over 1,550 meters and remains open. Lynx HW is showing good continuity and grades towards the NE. Lynx 4 has been extended 75 meters NE for a total current strike length of 1,350 meters and new infill drillholes continue to demonstrate continuity and robust gold grades between sections 3650E and 4225E.

The Windfall Lake gold deposit is located between Val-d'Or and Chibougamau in the Abitibi region of Québec, Canada. The mineral resource defined by the previous operator comprises 2,762,000 tonnes at 8.42 g/t Au (748.000 ounces) in the indicated category and 3,512,000 tonnes at 7.62 g/t Au (860,000 ounces) in the inferred category. The Windfall Lake gold deposit is currently one of the highest grade resource-stage gold projects in Canada. The bulk of the mineralization occurs in the Main Zone, a southwest/northeast trending zone of stacked mineralized lenses, measuring approximately 600 meters wide and at least 1.400 meters long. The deposit is well defined from surface to a depth of 500 meters, and remains open along strike and at depth. Mineralization has been identified only 30 meters from surface in some areas and as deep as 870 meters in others, with significant potential to extend mineralization up and down-plunge and at depth.
