About the Project

Monument Bay is located in northeastern Manitoba, near the Ontario-Manitoba border, and represents a district-scale exploration opportunity with significant gold and tungsten mineralization over a 40 km strike length. Monument Bay is an advanced stage exploration asset with over 233,000 metres drilled in more than 800 diamond core holes, while still having substantial exploration upside both within the known deposits and along underexplored satellite zones.

The Report describes the historical exploration work completed at Monument Bay, particularly in the period from 1987 to 2021, including geological mapping and prospecting, trenching, geochemical sampling, airborne magnetometer and VTEM surveying, local ground induced polarization and magnetometer surveys, local humus, B-horizon soil and biogeochemical surveys. A total of 233,410m of diamond drilling has been completed in 818 holes, mostly focused on the Monument Bay Au-W Deposit. In addition, 120 reverse circulation holes were completed between 2019 and 2021 on a very wide (1.5km X 1.5km) spacing across the property. Collectively, this work has resulted in multiple gold discoveries, most notably at the Monument Bay Au-W Deposit, Mid-East, AZ Zone and Gold Ridge areas along important regional deformational/shear structures.
