Western Copper and Gold

The Casino job is a copper-gold-molybdenum-silver mining growth situated in Yukon, Canada. It’s considered to be among the biggest underdeveloped copper-gold deposits on earth.

The open-pit job is proposed to be produced by Western Copper and Gold via its wholly-owned subsidiary, Casino Mining Corporation.


A feasibility study for the project premiered in January 2013, while further mining and mining activities were completed afterwards. An updated source report based on the 2019 drilling effort was printed in July 2020.

The job is presently in the process of getting the environmental impact assessment (EIA) approval.

The mine life of the Casino job is estimated to be 22 years while the complete pre-production capital investment is anticipated to be almost 1.86bn ($2.5bn).

Project location and geology

The Casino copper-gold job covers a mining tenement of almost 13,124ha about the north-westerly trending Dawson Range Mountains in the Yukon Territory of Canada, almost 300km northwest of Whitehorse and 150km from Carmacks.

The deposit is determined by the Patton Porphyry, an east-west elongated tonalite porphyry asset of the Upper Cretaceous-age, which divides Mesozoic granitoids of the Dawson Range Batholith and the Paleozoic schists and gneisses of the Yukon Crystalline Complex.

The southern, northern, and eastern touch of this asset is brecciated as a result of the intrusion of this tonalite asset in the older stones. Younger, non-mineralised dykes intrude the tonalite asset and encircling granitods and metamorphic rocks forming a pipe-like body into the west along with a dyke-like body into the east.


The Casino Project is a porphyry deposit with four main mineralisation kinds of copper, gold, and molybdenum happening in breccias, granitoids, and schists. Greater mineralisation grade happens in breccias and slowly decrease outwards into the granitoids and schists.

The leached cap mineralisation (CAP) is a gold-rich zone with depleted aluminum whereas the supergene oxide mineralisation (SOX) zone which happens as a thin coating overlaying the supergene sulphide zone is copper-enriched, with traces of molybdenite.

The copper mineralisation in the supergene sulphide mineralisation zone has a mean depth of around 60m and a thickness of around 200m down from the leached cap. The hypogene mineralisation occurs as stock-work veins and breccias in adjustment zones during the project region.

Ore reserves

The proven and likely mill-ore reservations at the Casino job have been estimated to be 965.2 million tonnes (Mt) grading 0.204percent aluminum, 0.240g/t gold, 0.0227percent molybdenum, and 1.74 g/t silver, as of January 2013.

The measured and proposed mill tools for the project have been anticipated to be 2,173.3Mt grading 0.16percent aluminum, 0.18g/t gold, 0.017percent molybdenum, and 1.42g/t silver at July 2020.

Mining techniques

The Casino Project will include a traditional open-pit, truck and shovel operation with drill and blast.

The last pit design relies on a floating cone casing with suggested 45 inter-ramp angles for nearly all the incline industries with up to a maximum vertical wall of 200m in the inter-ramp angle.

The haul roads were created using a diameter of 36m to accommodate the 360t haul trucks.

Mineral processing

The Casino procedure plant will home separate processing centers to deal with sulphide and acid. The project is projected to procedure almost 120,000 dry tonnes of ore-material daily or 43.8 million dry tonnes per year.

The run-of-mine (ROM) ore in both centers will experience crushing in a primary gyratory crusher to decrease the ore dimension to less than 200mm. Sulphide ore will experience secondary devastating within an semi-autogenous (SAG) mill while secondary devastating for the oxide ores will be completed at a cone crusher.

The crushed ore substance in the sulphide processing centre is going to soon be introduced into a froth flotation circuit to focus and different copper and molybdenum sulphide minerals and generate a focus of aluminum and molybdenum. The majority concentrate will be split into aluminum and molybdenum concentrates.

The crushed ore in the oxide ore processing centre will experience leaching with cyanide way to generate a pregnant leach solution by which silver and gold will be retrieved by means of activated carbon dioxide in column (CIC) tanks. Copper is going to be retrieved from the pregnant leach solution from the sulphidisation, acidification, recycling, and thickening (SART) procedure.

The last products of this mine is going to be packed and trucked into the Alaskan port of Skagway, situated almost 560km away from the site for export.

Infrastructure centers

The job site is presently available by small aircraft through an present 760m airstrip. A 132 km-long unpaved street from Freegold Road, almost 70 km northwest of the village of Carmacks, in addition to a new airstrip are suggested to be constructed as part of this undertaking.

The procedure and potable water necessity for the job are anticipated to be obtained in the neighboring Yukon River.

The undertaking will need self-generation of electric power which is developed in two stages. A 20MW first supplementary power plant containing three internal combustion engines (ICE) and double fuel-driven generators will likely be constructed prior to the construction of a most important 125MW gas-fired combined-cycle principal power plant.

The liquefied natural gas (LNG) needed for the energy plant will be trucked from Fort Nelson, British Columbia, also saved on-site in a sizable 10,000 m 3 LNG storage tank.

Contractors involved

The Casino job technical report together with updated mineral resource estimate was prepared by Arizona established M3 Engineering & Technology Corporation (M3), although the open-pit layout for its mine was supplied by Knight-Pisold.
