QUEBEC – Eastmain Resources of Toronto is advancing its Eau Claire gold-silver project in the James Bay area. The company will undertake engineering studies for an underground exploration ramp as well as environmental and infrastructure studies.

In May 2018, Eastmain released a preliminary economic assessment that put the after tax net present value (with 5% discount) at $260 million and an after tax internal rate of return of 27%. A measured and indicated resource of 2.4 million tonnes grading 6.53 g/t gold was used in the study. The mine would consist of two small open pits followed by underground operations over 12 years.

The company plans to drive a ramp so that a 25,000-tonne bulk sample can be collected for metallurgical and process testing.

Elsewhere on the Clearwater pr

operty, which includes the Eau Claire deposit,  a surface exploration program is underway. In September the company plans to complete a 1,600-metre trenching program to investigate the Cannard deformation zone along the southern boundary of the property. A 5,500-metre diamond drill program is planned this fall to further test the zone
