 First Mining Gold Corp TSE:FF OTCQX:FFMGF FRA:FMG said it has now filed its previously announced pre-feasibility study PFS for the Springpole gold project in Ontario, which shows the property has the potential to become a strategically significant, highly profitable gold mine. As reported in January this year, the study envisages recovering gold and silver from a 30,000 tonne-per-day tpd open-pit operation, over a mine life of 11.3 years.
