Cuprum Metals is a US-based company specializing in innovative copper extraction technologies that enhance operational efficiency and sustainability in mining processes.

Cuprum Metals was established to address the inefficiencies in traditional copper mining processes, leveraging a patented approach to enhance extraction rates.Cuprum Metals specializes in a patented leaching technology that facilitates the efficient extraction of copper from copper sulfide ores, which comprise 80% of global copper deposits. This innovative process circumvents the passivation layer effect, allowing for direct oxidation of copper while achieving high yield in minutes rather than days. The technology is adaptable to various mining methods, including vat, agitation, and heap leaching processes, making it versatile for different operational setups. With a focus on environmental sustainability, Cuprum Metals also aims to repurpose residual materials from the extraction process into non-toxic alternatives suitable for use in construction and mine-fill. The company primarily markets its services to mining operations on a global scale, targeting regions with significant copper mining activities, such as South America, North America, and parts of Africa.Cuprum Metals generates revenue through partnerships with mining companies that integrate their proprietary leaching technology into existing operations. The business model typically involves direct contracts where Cuprum Metals provides its patented lixiviant and technical support for the leaching process. Transactions are structured as B2B agreements, often encompassing service fees for technology implementation and ongoing consultation. Financial arrangements may include revenue-sharing models based on the amount of copper extracted using their technology, thus enhancing the profitability of their clients' copper mining operations.In June 2026, Cuprum Metals raised USD 19.4 mn in Series A funding led by Lundin Family Office, with participation from Woodline Partners and BHP Ventures. The company plans to utilize this funding to support copper exploration and development activities, aiming to improve their mining technologies further. Additionally, Cuprum Metals is targeting expansion into new markets, focusing on key regions with burgeoning copper mining industries, which will be pursued in the near future.
