Quaise and Nevada Gold Mines partner on deep geothermal pilot plant
Quaise Energy, Inc. and the Barrick-operated Nevada Gold Mines (NGM), a joint venture with Newmont Corp., are exploring additional decarbonisation of NGM’s TS Power Plant by using geothermal heat from NGM’s land and subsurface holdings to hybridise on-site power generation.

Quaise Energy, Inc. and the Barrick-operated Nevada Gold Mines (NGM), a joint venture with Newmont Corp., are exploring additional decarbonisation of NGM’s TS Power Plant by using geothermal heat from NGM’s land and subsurface holdings to hybridise on-site power generation.
Quaise and Nevada Gold Mines partner on deep geothermal pilot plant
NGM recently completed construction of a 200 MW solar power plant and is currently in the process of modifying the TS Power Plant to use cleaner-burning natural gas as a fuel source. In partnership with Quaise, NGM is investigating deep geothermal energy sources to further reduce the plant’s fossil fuel consumption and greenhouse gas (GHG) emissions.
The partnership underscores the unique capabilities of deep geothermal to decarbonise heavy industrial sectors like mining, and marks the first commercial pilot for retrofitting a fossil fuel power plant to accommodate geothermal heat. This is well aligned with NGM’s 2030 GHG reduction roadmap targets.
Henri Gonin, Managing Director of Nevada Gold Mines, comments:
“Nevada Gold Mines is targeting an overall 30% reduction in GHG emissions by 2030. We continue to pursue initiatives that economically reduce our reliance on carbon-based electricity sources. Quaise offers a unique prospective solution to hybridise our on-site power generation with clean geothermal heat.”
The partnership highlights two key reasons why going deeper is a necessity for geothermal to achieve a significant share of the global energy mix by 2050. The first is location. Deep geothermal wells can be drilled in more places around the world, even next to existing power plants. The second is economics. Deep geothermal can compete with fossil fuels on cost while eliminating carbon emissions by producing as much as 10x more power per well than traditional geothermal.
Carlos Araque, President and CEO of Quaise Energy, said:
“Deep geothermal can decarbonise critical industrial processes like mining because of its superior power density. Our millimetre wave drilling technology is the key to unlocking high-grade geothermal heat, repositioning fossil-fired assets for a clean energy future.”
The retrofit of NGM’s TS Power Plant positions Quaise to go from drilling field trials to full commercial deployment. The ongoing partnership opens a prospective new paradigm in clean energy for industrial use applications worldwide.
