Ardiden Managing Director and CEO, Mr Greg Romain, commented: “Ardiden is highly appreciative of this OJEP exploration grant from the Ontario Ministry of Mines. Forwardthinking exploration initiatives such as OJEP supplements qualified junior exploration companies access to the venture capital required to identify and advance early-stage exploration projects in Canada.” Ontario Minister of Mines, George Pirie said: “Our government is supporting junior exploration companies such as Ardiden to locate Ontario's mines of the future that will build stronger communities and lay the foundation for our next generation,” said George Pirie, Minister of Mines. “That’s why we launched the Ontario Junior Exploration Program (OJEP), to encourage early exploration, help drive economic development, secure domestic supply chains and create jobs throughout Ontario, especially in northern and Indigenous communities.” Project Update Ardiden continues to evaluate historical results and assess opportunities to advance the Pickle Lake Gold Project while taking a prudent approach to managing capital in the current financial markets.
