Greenstone Gold Mines \u2013 a 50:50 joint venture of Centerra Gold and Premier Gold Mines \u2013 has received approval from the provincial environment ministry for development of the Hardrock gold mine 2 km south of Geraldton, Ontario. Federal approval was received late last year.<\/p>\n
An open pit and 27,000 t\/d mineral processing plant are planned. The pre-production capex will be near C$1.25 billion to create a project that produces an average of 300,000 oz. of gold over a 14.5-year mine life. The project has a an expected after tax net present value (5% discount) of $818 million, an internal rate of return of 17.5%, and a payback period of 4.5 years.<\/p>\n
The project has probable open pit reserves of 141.7 million tonnes grading 1.02 g\/t gold for 4.6 million contained oz. Both the indicated and inferred estimates contain underground as well as open pit resources. The cut-off for pit material is 0.30 g\/t and for underground is 2.0 g\/t. Using those numbers, the indicated resource is 25.1 million tonnes at 2.29 g\/t gold for 1.9 million contained oz., and the inferred portion is 21.7 million tonnes at 3.55 g\/t gold for 2.5 million contained oz.<\/p>\n
The 2019 work plan for Hardrock is to advance the permitting process, proceed with detailed engineering, drill a further 18,000 metres to update reserve and resource estimates, incorporate the optimization work that was done over the past two years, and update the project economics.<\/p>\n
