Osisko Mining Inc. provided 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 metre drill program combines definition, expansion and exploration drilling in and around the main Windfall gold deposit and the adjacent Lynx deposit (located immediately NE of Windfall). Significant new analytical results from 57 intercepts in 32 drill holes focused on infill and expansion drilling in the Underdog area of the Main Windfall Lake deposit are: Drilling continues to infill zones of mineralization in Underdog through the application of the Windfall geological model, new mineralization has been discovered 140 metres to the southwest of previously defined Underdog zones. Highlights from the new results include: 76.5 g/t Au over 5.0 metres in OSK-W-17-1275; 29.1 g/t Au over 3.6 metres, 59.5 g/t Au over 2.1 metres, and 9.65 g/t Au over 10.4 metres in OSK-EAG-13-480; 11.9 g/t Au over 9.0 metres in OSK-W-17-1125; 24.4 g/t Au over 4.0 metres in OSK-W-17-1336; 42.9 g/t Au over 4.1 metres in OSK-W-17-13361W1; 38.7 g/t Au over 2.0 metres in OSK-W-17-1259; 22.3 g/t Au over 2.2 metres in OSK-W-17-1249; 20.4 over 2.0 metres in OSK-W-17-1239; and 13.3 g/t Au over 3.6 metres in OSK-OBM-16-693. OSK-EAG-12-399 intersected FW3U with 5.57 g/t Au over 2.5 metres and 5.21 g/t Au over 2.1 metres. Mineralization is composed of 7% disseminated pyrite in a strongly sericitized andesite at the contact with a moderately sericitized felsic porphyritic dike. OSK-EAG-13-480 intersected nine intervals: 29.1 g/t Au over 3.6 metres related to FW1, 4.67 g/t Au over 3.0 metres in FW1 FW, 4.09 g/t Au over 2.8 metres, 19.5 g/t Au over 2.0 metres, 59.5 g/t Au over 2.1 metres in FW2, 9.65 g/t Au over 10.4 metres, 6.44 g/t Au over 2.6 metres in FW3 and 7.04 g/t Au over 2.2 metres, 5.90 g/t au over 2.0 metres in FW3U. The first interval is composed of up to 7% pyrite stringers, local visible gold, disseminated pyrite, chalcopyrite and sphalerite with local tourmaline ptygmatic veins hosted in a porphyriticc felsic dike. Moderate sericitization and pervasive silica flooding are present. The second interval is composed of 1% pyrite stringers and traces of disseminated pyrite in a sericitized porphyritic felsic dike. The three intervals in FW2 are composed of 1% pyrite stringers, 2% disseminated pyrite in pervasive silica flooding, hosted in a sericitized porphyritic felsic dike with fuchsite. The sixth and seventh intervals in FW3 are composed of up to 10% pyrite associated withlocal pervasive silica flooding within a silicified and moderately sericitized porphyritic felsic dike with fuchsite. The eighth and ninth intervals in FW3U, are composed of 1% pyrite stringers, 2% pyrite in pervasive silica flooding within a strongly silicified and sericitized porphyritic felsic dike.
