Name of the Project
Magino gold project.
Location
The project is located 40 km north-east of Wawa, Ontario, Canada.
Project Owner/s
Canada-based mining company Argonaut Gold.
Project Description
Magino is a past-producing underground gold mine.
The project has total proven and probable reserves of 59-million ounces grading 1.13 g/t gold. A feasibility study on the project has identified it as a strategic, long-life asset.
Envisaged is a 115 700 oz/y gold operation with a 17-year mine life. Average gold production of 150 000 oz/y is expected over the first five years.
Openpit mining operations will use a fleet comprising 16 m3 front shovels, a 13 m3 front-end loader and 140 t haul trucks. This fleet will be supplemented by drills, and graders, as well as track and rubber-tyre dozers.
A 10 000 t/d processing facility has been selected for the feasibility study, compared with the 30 000 t/d plant presented in the January 2016 prefeasibility study.
The adopted flowsheet includes primary crushing, single-stage semiautogenous grinding mill, a gravity recovery circuit, a cyanide leach and carbon-in-pulp gold adsorption circuit with cyanide recovery and detoxification, as well as thickening, before tailings are discharged to a tailings facility.
Potential Job Creation
During construction, about 500 to 600 jobs will be created and about 350 employees will be engaged as part of ongoing operations.
Net Present Value/Internal Rate of Return
The project has a pretax net present value, at a 5% discount rate, of $408-million and an internal rate of return of 22.6%, with a payback of 3.8 years.
Capital Expenditure
The project has an initial capital estimate of between C$480-million and C$510-million, of which an estimated 40% is covered by a fixed-bid contract with Ausenco Engineering Canada. The project is considered fully financed through Argonaut's current cash balance and expected cash flow from operations, assuming a gold price environment at or above $1 600/oz.
Planned Start/End Date
Argonaut envisions a two-year construction period, with first gold production at Magino expected to start during the first half of 2023.
Latest Developments
The Canadian province of Ontario has filed the closure plan for the Magino project. Site preparation, such as tree removal and clearing, is expect to start imminently, with construction to begin as soon as site preparation is complete.
