Gaboury Project

The management of the company would also like to mention that it has obtained all the necessary permits to undertake a first drilling program on its Gaboury project located 150 KM SW of Rouyn-Noranda, in Abitibi (Québec). A first prospecting survey made it possible to trace in the western extension of the Pike Nickel showing, a few significant nickel anomalies as well as copper, zinc, and silver anomalies in the eastern extension of the same showing. The drilling campaign should starts as soon as possible.
