Breakthrough Copper Recovery and Sustainable Energy Initiatives
Exceptional Copper Recovery at Kalaba Project
Terra Metals Inc., alongside its local partner Lunda Resources Ltd., has made significant strides at the Kalaba Copper Project. This development, validated through rigorous testing by Dr. Yotamu Hara of YCS Sustainable Solutions Ltd., reveals a staggering flotation recovery rate of 96.5%. The concentrate grades achieved are notably impressive, with 26.91% copper for sulphide concentrates and 4.31% for the oxide variant. Such high recovery rates mark a pivotal moment in mineral extraction, particularly emphasizing the capabilities present in oxide-dominant ores.
Innovative Approaches to Copper Processing
The advancements at Kalaba are rooted in state-of-the-art flotation techniques. Utilizing advanced chemical processes, specifically CMC depressants, Terra Metals has successfully navigated challenges posed by high talc content in the ore, which can reach up to 54%. This innovation not only optimizes recovery but also addresses previously limiting factors in processing copper and cobalt ores.
In addition, the ore's ability to be upgraded through low-cost leaching methods using solvent extraction positions Kalaba among the continent's leaders in low-cost and environmentally friendly copper production.
A Green Model for Critical Minerals
Environmental stewardship is central to Terra Metals' operations. The company has secured full environmental clearance from the Zambia Environmental Management Agency (ZEMA), signifying its commitment to sustainable mining practices. Moreover, the establishment of a 5 MW solar energy facility highlights the company's forward-thinking approach. This facility is set to expand to 100 MW, facilitating carbon-neutral production of both copper and cobalt.
With these initiatives, Terra Metals aims to pioneer large-scale green production in Zambia, standing out as a model for responsible critical minerals mining powered predominantly by renewable energy sources.
Community Engagement and Support
A cornerstone of the Kalaba Project's progress is the support received from local leadership. Terra Metals greatly appreciates the ongoing collaboration with His Royal Highness Senior Chief Sailunga and Chief Ntambu from the Lunda community. Their involvement has been integral to ensuring that development is conducted with respect and integrity toward local customs and communities.
Strategic Exploration and Future Plans
Beyond the exciting developments at Kalaba, Terra Metals holds an extensive exploration license through Central Africa Renewable Energy. This license covers a highly prospective copper-cobalt zone adjacent to Ivanhoe’s acclaimed Kamoa-Kakula Mine in the DRC Copperbelt, indicating substantial potential for future discoveries and advancements.
Looking ahead, several key milestones are on the horizon. An NI 43-101 compliant resource estimate is anticipated in the near future, along with the commissioning of a 240TPH concentrator planned for September. The subsequent solar expansion to 100 MW will further bolster their production capabilities, alongside exploration initiatives at the bordering DRC tenement.
Chairman’s Vision for the Future
Mumena Mushinge, Chairman of Terra Metals Inc. and Lunda Resources, articulates their vision, stating, "This isn’t just a technical success—it’s a declaration that Zambia can lead responsibly in solar-powered production of critical minerals. Kalaba serves as a testament to the power of innovation, sustainability, and community engagement in generating tangible value." This statement underscores their commitment to shaping the future of mineral production in a manner harmonious with environmental objectives.
