Star Metro - Cotec Investment Ceibo Partners with Glencore's Lomas Bayas to Support Revolutionary Copper Leaching Technology

Following two years of testing by Glencore, Lomas Bayas has validated Ceibo's technology and is scaling up testing to assess if Ceibo's technology is an alternative to extend the life of their mining operations. Testing will begin on-site through Lomas Lab, a Glencore world-class test site. This agreement demonstrates Ceibo's technical progress towards commercialisation with a major mining company and affirms the potential value that Ceibo's advanced leaching technologies could bring to copper assets globally.

Julian Treger, CoTec CEO commented, "We are very pleased that Ceibo has completed this agreement with Lomas Bayas. This represents a major step in the scaling of their technology and further demonstrates the attractiveness and potential of the technology in large, long life, copper sulphide deposits. Ceibo has been making good progress over recent years and CoTec has started the process to identify assets for Ceibo to commercially deploy its technology."

Ceibo has developed a revolutionary process to leach low-grade primary copper sulphides, such as chalcopyrite, and copper waste material using a proprietary high throughput inorganic leaching technology. Ceibo's leaching processes extract copper in all sulfides using existing leaching plants. This process more quickly and effectively catalyzes the oxidation in the ore through electrochemical reactions, resulting in higher recovery rates in shorter operational cycles.

If scaling is successful, CoTec believes that Ceibo's technology will represent a leading, low-carbon, high recovery primary and waste copper sulphide heap leaching process. This could deliver considerable value through a significant reduction in the time required to bring additional copper into production, a competitive cost structure and a lower environmental and carbon footprint, protected by a high technical barrier to entry.

CoTec participated in Ceibo's Series B financing round in 2022, which was led by Energy Impact Partners and a syndicate of mining-focused investors, including - in addition to CoTec - BHP Ventures, Orion Industrial Ventures and Unearth Capital, together with existing investors Khosla Ventures and Aurus Ventures. In total, Ceibo raised over US$30 million in the Series B financing.
