Ceibo, a Chilean advanced copper extraction technology company, has announced that BHP Ventures has joined as investor, closing its Series B financing for over US$30 million to accelerate its primary and secondary sulphides leaching process.

Ceibo says it has put together a consortium of world leading financial investors and mining companies, which are collaborating and supporting the commercial role of its low carbon technology. They include Energy Impact Partners, leading the Series B, and a syndicate of mining-focused investors, including CoTec Holding, Audley Capital, Orion Industrial Ventures, Unearth Capital and Opalton (Pincus Green), in addition to the existing investors Khosla Ventures and Aurus Ventures.

The Chilean company is focused on continued onsite testing and engineering during the last quarter of this year. The technology developed by Ceibo targets chalcopyrite and other refractory copper minerals containing 70%+ of known copper reserves. Ceibo has developed a broader set of clean technologies in recent years that are being operated by Ceibo’s team in different mining districts, helping to achieve more efficient operations and generating a positive environmental impact.

“This capital increase, together with the strategic support of investors like BHP Ventures, will help us accelerate plans to deploy our technology globally and meet society’s needs, ” said Cristóbal Undurraga, Ceibo CEO and Co-Founder.
