The largest undeveloped gold project in Atlantic Canada is about 80 km southwest of the communities of Millertown and Buchans, Newfoundland. The five deposits contain 56.7 million measured and indicated tonnes at 1.72 g/t gold for 3.1 million oz. There is also an inferred portion of 18.2 million tonnes at 1.70 g/t gold, containing 1.0 million oz.
Marathon is planning a conventional truck and shovel open pit with average annual production of 173,000 oz. gold per year for the first nine years of operation. Gold will be recovered in a conventional mill that includes gravity concentration, flotation and carbon-in-leach. A heap leach is also proposed.
The 2021 feasibility study outlined a project with a net present value with a 5% discount rate of C$600 million and an internal rate of return of 31.5% after taxes, using $1,500/oz. gold. The all-in sustaining cost per ounce of gold produced is anticipated to be $833. The initial capex of C$305 will be paid back after taxes in 1.9 years. The mine has a projected life of 13 years.
