Rainy River Gold Project

The Rainy River Gold project is an advanced-stage gold project situated in the Richardson Township, approximately sixty-five kilometres northwest of Fort Frances in Northwestern Ontario. The property has excellent infrastructure, with year-round road access and powerlines in close proximity, as well as a railway located 21 kilometres to the south of the property. The Fort Frances area has a population of approximately 10,000 people from which a workforce could be sourced for future development.

On April 10, 2013, Rainy River announced the results of a Feasibility Study for the project, with 4.0 million ounces in Proven and Probable gold reserves and 6.2 million ounces in Measured and Indicated gold resources, inclusive of reserves. The Feasibility Study contemplates a 21,000 tonne per day processing rate from a combination of open pit, underground and stockpiled ore. The project has the potential to produce over 225,000 ounces of gold annually, at below industry average cash costs⁽¹⁾, for an initial mine life of 16 years. The Feasibility Study also highlights the potential to process higher grade ounces in the project’s early years, while stockpiling lower grades for processing towards the end of the mine life. This should help drive higher production and lower costs at the beginning of the mine life, enhancing both cash flow and the overall economics of the project.
