Among the latest highlights, from 44 intercepts in 30 holes at the Lynx deposit, Osisko reported 6.2m at 301g/t Au from 912m; and 2.6m at 79.4g/t from 341.7m.
CEO John Burzynski recently described the ongoing 800,000m effort at Windfall and the adjacent Lynx deposits at Urban Township as the "shut up and drill, stupid" programme.
The company closed a C$92.4 million (US$72.5 million) bought deal private placement of common and flow-through shares last month to bolster its exploration kitty.
The project has a 1.6 million ounce indicated and inferred resource established by the previous owners in 2015 and Burzynski said he expected the new resource would be based on only a portion of infill drilling at Windfall and about the first 700m of Lynx.
