Osisko Chief Executive Officer John Burzynski commented: “Infill drilling at Windfall, and in particular Lynx, continues to progress well. Predictably, and with a familiar consistency, once again Lynx delivered on high-grade with our headline intercept of 395 g/t Au over 2.3 metres, and also on width with the very nice intercept of 61.5 g/t Au over 9.2 metres.”
