The Wawa Gold Project benefits from strong local infrastructure and excess regional mill capacity.

This phased approach is aimed at de-risking development, accelerating time to revenue and minimizing shareholder dilution. The approach is subject to the completion of a number of milestones before a production decision can be made, such as continued drilling and mineral resource definition, conducting additional metallurgical testwork, completing a pre-feasibility study, continuing baseline studies as well as additional permitting and Indigenous peoples consultations, among other factors.

The Wawa Gold Project currently hosts mineral resources from two mineral deposits, namely the Jubilee Shear and the Minto Mine. The mineral resource includes an indicated mineral resource of 22.909 million (“M”) tonnes grading 1.69 grams per tonne gold (“g/t Au”) containing 1,244,000 ounces of gold and an inferred mineral resource of 9.951 M tonnes grading 1.59 g/t Au containing 509,000 ounces of gold, with both open pit and underground mining potential. Gold mineralization extends to surface on a historic mining property, which supports the Company’s phased development strategy.
