Osisko Extention and Infill Drilling Intersects High Grade at Lynx and Triple Lynx

948 g/t Au Over 2.4 Metres
360 g/t Au Over 2.1 MetresTORONTO, March 09, 2020 (GLOBE NEWSWIRE) — Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new drilling results from the ongoing definition and expansion drill program at its 100% owned Windfall gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.The program is currently focused on the Lynx deposit, exploration on the main mineralized zones, and deep exploration in the central areas of the mineralized intrusive system. Nineteen drills are active at Lynx and Triple Lynx.Osisko President and Chief Executive Officer John Burzynski commented: “This first major set of new drill results following, and not included in, last month’s mineral resource estimate update continues to show high-grade results from Lynx in both infill and expansion holes. The drilling demonstrates very good potential for further growth of scale and grade at Lynx. While the focus of the drill program is on resource definition, the exploration team is excited about targeting several key areas of the Lynx deposit for growth potential, in particular a down-plunge projection where we believe Lynx Extension and Triple Lynx zones may intersect.”The first results table below lists expansion intercepts located outside the February 2020 mineral resource estimate wireframes (see Osisko news release dated February 19, 2020).  The second table shows infill intercepts designed for resource definition. Significant new analytical results from 173 intercepts in 57 drill holes, 31 wedges, and 3 extensions of previously completed holes are presented below.Selected high-grade intercepts from new results include: 948 g/t Au over 2.4 metres in OSK-19-2226; 360 g/t Au over 2.1 metres in OSK-W-19-2164; 72.0 g/t Au over 5.1 metres in OSK-W-19-2197-W1; 139 g/t Au over 2.0 metres in OSK-W-20-1104-W7; 71.2 g/t Au over 3.4 metres in OSK-W-19-1731-W4; 113 g/t Au over 2.0 metres in WST-19-0266; 19.0 g/t Au over 11.2 metres in OSK-W-19-2100-W5; 58.4 g/t Au over 3.2 metres in OSK-W-19-2123-W3; 92.6 g/t Au over 2.0 metres in OSK-W-19-991-W9; 51.0 g/t Au over 3.2 metres in WST-19-0198  and 41.1 g/t Au over 3.5 metres in OSK-W-19-991-W10.
