Black Fox produced 5,200 GEOs during the period, compared to 8,300 GEOs in Q1 2020.

A new 10-year agreement has been reached between the El Gallo operation and the neighbouring communities.

COVID-19 Update

The worsening COVID-19 infection rate in Ontario is being closely monitored; to date it has not had a material impact on operations or exploration activities at the Fox Complex.
