About the Martello Gold Project

The Martello Gold Project is Richmond Hill Resources plc’s principal gold exploration asset, located near Dryden in north-western Ontario, Canada, within the Western Wabigoon Subprovince. The project comprises 202 mining claims covering approximately 6,750 hectares and hosts historic gold workings and multiple exploration targets.

The Company’s immediate exploration focus is the historic Sakoose gold mine, where past production and historical drilling provide evidence of high-grade gold mineralisation. Planned diamond drilling will test the continuity and geological controls of this mineralisation. Historical results do not establish a current mineral resource or demonstrate the economic viability of future mining.
