Gold
Opened
2013-01-01
Workforce
approximately 40 staff
Processing
Ore from the Rosemont underground mine is processed at a crushing and grinding circuit at the Rosemont site, which has a capacity of 1.5 million tonnes per annum. The ore is then pumped as a slurry via a 10-kilometre pipeline to the Garden Well processing plant for leaching and gold recovery through a carbon-in-leach (CIL) circuit.
Expansion
Regis Resources is currently developing the Rosemont Stage 3 extension, which is located south of the existing underground operations and will extend mining to a depth of 700 metres below the surface. This extension has a mining inventory of 1.7 million tonnes at a grade of 2.8 g/t for 157,000 ounces of contained gold, which includes a Probable Ore Reserve of 490,000 tonnes at 2.6 g/t for 41,000 ounces of gold. The Rosemont Stage 3 is expected to have an annualised gold production target of 40,000 to 50,000 ounces. The scheduled underground ore mining rate for this extension is up to approximately 600,000 tonnes per annum.

Overview
Red Chris Mine is an operating open pit mine in British Columbia, Canada, currently transitioning to an underground block cave operation. It produces copper, gold, and silver. The mine is owned 70% by Newmont Corporation (operator) and 30% by Imperial Metals Corporation.
Production
Production overview - 2025: copper 93101213 lbs, gold 92429 oz; 2024: copper 85320618 lbs, gold 59811 oz.
Processing
The plant uses conventional crushing, grinding and flotation to produce a gold-copper concentrate. The circuit includes a semi-autogenous mill, a ball mill, and a pebble crusher. Concentrate is trucked to the Port of Stewart for shipment to smelters.
Equipment
Conventional truck and shovel fleet, including a P&H 2800 electric cable shovel and Caterpillar 793 haul trucks.
Expansion
The mine is undergoing a major expansion to transition from open-pit to an underground block cave operation. The project has a projected capital cost of C$2.6 billion to $3 billion. The expansion is being fast-tracked through the federal government's Major Projects Office and is forecast to create up to 1,800 construction jobs. A feasibility study for the block cave is expected to be completed in the second half of 2026. Perenti subsidiary Barminco was awarded a contract extension for the development of the underground exploration decline.

Overview
The development plan involves a two-stage construction of an open pit mine and a process plant. Stage one is designed for the lowest capital cost and shortest payback period. Stage two will be an expansion, with the investment decision expected between 2031-2033. The ultimate processing capacity is planned to be 14Mtpa. The processing flowsheet will produce two smelter-grade concentrates (a copper concentrate and a nickel concentrate) and a palladium-platinum-gold doré.
Production
Production overview - 2025: nickel 7000 t, copper 8000 t, cobalt 700 t.
Processing
The processing flowsheet will produce two smelter-grade concentrates (a copper concentrate and a nickel concentrate) and a palladium-platinum-gold doré. A hydrometallurgical process is no longer required.
Expansion
The Pre-Feasibility Study (PFS) covers an initial 23-year open-pit mine life, which exploits about half of the Gonneville resource. There is significant potential for expansion through deeper open-pit mining or a large-scale underground operation beyond 2054. Stage two will be an expansion, with the investment decision expected between 2031-2033.
