New Prosperity

New Prosperity Project Map

One of Canada's largest undeveloped copper-gold projects, New Prosperity has the potential to create significant economic and social value, both in and beyond British Columbia.

The New Prosperity deposit is a gold-copper porphyry with a one billion tonne measured and indicated resource containing 5.3 billion pounds of copper and 13.3 million ounces of gold. At long-term gold and copper prices the project has robust economics.

New Prosperity is a project that holds the potential to dramatically increase shareholder value and improve the economic well-being of local communities. Development of this large-scale deposit would be a major step towards transforming Taseko into a strongly positioned mid-tier mining company.


  • Large undeveloped gold-copper project: A one billion tonne measured and indicated resource containing 5.3 billion pounds of copper and 13.3 million ounces of gold**.
  • 831M tonne proven and probable reserve grading 0.23% copper and 0.41 gpt gold**.
  • 25+ year mine life processing 70.000 tonnes per day
  • Annual production averaging 110 million pounds copper and 230,000 ounces gold over the mine life


In December 2019, the Tŝilhqot’in Nation, as represented by Tŝilhqot’in National Government, and Taseko entered into a confidential dialogue, facilitated by the Province of British Columbia, to try to obtain a long-term solution to the conflict regarding New Prosperity, acknowledging Taseko’s commercial interests and the Tŝilhqot’in Nation’s opposition to the project. The dialogue was supported by the parties’ agreement to a one year standstill on certain outstanding litigation and regulatory matters that relate to Taseko’s tenures and the area in the vicinity of Teẑtan Biny (Fish Lake). The Tŝilhqot’in Nation and Taseko have made progress in establishing a constructive dialogue and in December 2020 the parties agreed to extend the standstill for an additional one year period.

Readers are cautioned that the Prosperity Technical Report has not been updated since 2009 and accordingly, caution needs to be advised when assessing its conclusions in light of current operating and capital costs, appropriate technologies, metals price outlooks, and like matters.
