Taseko Mines Limited is a mid-tier copper producer located in British Columbia, Canada. It operates Gibraltar Mine, the second largest open-pit copper mine in Canada, and is in the planning stages for several other mines including the Prosperity Mine, Harmony, and Aley. All production is sold at non-hedged market based prices. The market capitalization currently is roughly 740 million dollars.
Gibraltar Mine.
Operations: Large open pit mine with production ranging from 80-110 million lb copper per year at a cost of $1.20 per lb mined once phase II expansion has been completed.
Reserves: 2.4 billion pounds of copper and 69 million pounds of molybdenum

Opposition by Tŝilhqot’in First Nation.
In March 2021, the Tŝilhqot’in National Government challenged the permit that allows the mine to dump wastewater into the Fraser River on historical Tŝilhqot’in lands.
Between April and November, the mine dumps up to 24 million litres (about 10 Olympic-sized swimming pools) of untreated mine waste into the Fraser River every day. 
Prosperity Mine.
The property includes 85 square km in south central British Columbia. A large copper and gold mineralization has been defined on the property containing around 5.3 billion lb copper and 13.3 million oz of gold. The feasibility for the mine was completed on September 25, 2007 and the environmental review process began in July 2008.
Operations: Large open-pit copper and gold mine with projected production of 108 million lb per year and 247,000 oz of gold per year for 20 years.
Reserves.
Cost: ~800 million
In 2009, proven reserves for the mine were 481 million tonnes 0.46 gram per tonne of gold and 0.26 per cent copper. Probable reserves were estimated at 350 million tonnes grading 0.35 gram per tonne of gold and 0.18 per cent of copper (based on a $5.50 net smelter return cut-off).
Harmony Mine.
The Harmony property is located on Graham Island, the largest island of the Haida Gwaii archipelago, within the Queen Charlotte Islands, off the coast of British Columbia. The property contains a low-grade gold mineralization that can only be mined profitably at historically high gold prices. Teseko has yet to explore this property and values the property at $1 on its balance sheet as of September 2004.

Location: Aley.
The Aley asset contains Niobium, a rare metal used in the production of special steel alloys that are corrosion resistant. Currently only 2 mines in the world produce the rare metal. The spot price of this metal has risen significantly in the last 5 years, from has low as $6.70 per lb in 2004 to ~$24.00 currently . The property is located near the shore of the lake, about 30 kilometers from the Camp. The price of
