The program is currently focused on infill drilling and expansion drilling at the Lynx deposit, exploration on the main mineralized zones, and deep exploration in the central areas of the mineralized intrusive system. Twenty-two drills are active at Lynx and Triple Lynx, with another two drills conducting infill and exploration drilling on other areas of the deposit.
Osisko President and Chief Executive Officer
Significant new analytical results from 71 intercepts in 17 surface drill holes and 19 wedges focused on Lynx infill and expansion drilling are presented below. Additionally, 11 intercepts from 9 underground infill drill holes, including the Lynx bulk sample area, are included in the table below.
Intercepts from new results include: 491 g/t Au over 3.3 metres in OSK-19-1193-W2; 161 g/t Au over 8.0 metres in OSK-W-19-2068-W2; 267 g/t Au over 2.7 metres in
