At GCR Group, we operate a globally diversified set of polymetallic assets across Africa and South America—producing copper, nickel, cobalt, platinum, and palladium from single mining sites. From Tataki (Botswana) and Chile, this strategy delivers operational efficiency, revenue diversification, and resilience in volatile markets.
Our integrated mining model combines precision extraction and on-site processing to maximize metal recovery. We use technologies like XRT sorting (TOMRA) to reduce waste and improve energy efficiency. Further processing through DMS and hydrometallurgical leaching ensures high-yield, low-impact results.
In Chile, our MTV Process produces high-purity copper cathodes. Other sites use methods like Vertical Hole Leaching to recover value and extend mine life.
This tech-driven approach delivers market-ready products—copper cathodes, PGMs, and nickel/cobalt hydroxides—strengthening global supply chains for clean energy and infrastructure.
At GCR Group, we apply a multi-stage process to produce high-purity copper cathodes. It begins with 3–4-stage crushing and agglomeration, adding 20 kg/t of NaCl for optimal ore conditioning.
The ore undergoes leaching: a 30-day rest, followed by a 60–90-day irrigation cycle, extending up to 180 days for full extraction.
Final recovery uses Solvent Extraction and Electrowinning (SX-EW), with coalescers and washing to reduce impurities—delivering premium-grade copper at scale.

In copper production, crushing plants are the first key step in processing mined ore. They break down large rocks into smaller, manageable pieces, typically through multiple stages of crushing.
This size reduction is essential to prepare the ore for further processing—such as grinding, leaching, or flotation—so that valuable copper minerals can be efficiently extracted.

The ORML Project (Old Ripios Massive Leaching) offers an innovative and cost-effective solution to access old copper ore inventory without expensive material movement. By injecting leaching solutions directly through a mesh of vertical holes, the process optimizes acid consumption and makes large scale leaching economically viable.
This breakthrough is powered by GCR Group’s proprietary MTV innovation—Vertical Hole Leaching (VHL) which revolutionizes acid use and overcomes traditional leaching challenges.

GCR Group operates across two continents, strategically positioned in the world’s most resource-rich regions. In South America, we leverage Chile’s vast resources, infrastructure, and mining-friendly regulations. In Africa, we operate in Botswana, accessing top copper and cobalt deposits. This global presence supports our mission to lead in critical minerals through sustainability, innovation, and long-term value.
South America is a global mining powerhouse, with Chile leading as the world’s top copper producer.
Chile offers vast, high-grade mineral reserves, stable and supportive mining regulations, and well developed infrastructure. The country’s unique geology and investor-friendly climate make it a prime destination for efficient, large-scale copper extraction essential to the global energy transition.
Minera Tres Valles (MTV) is a producing copper operation located in the Coquimbo Region of Chile, one of the world’s most stable and mining-friendly jurisdictions. The site combines open-pit and underground mining at Don Gabriel and Papomono, supported by a state-of-the-art SX-EW plant to produce Grade A (99.99%) copper cathodes.
In addition to its own ore, MTV processes material from local small-scale miners, contributing to regional development and employment. Over 60% of the workforce is locally sourced, and third-party mining is supported through formalized access agreements.
With strong commitments to sustainability, safety, and community engagement, MTV plays a key role in both GCR Group’s copper growth strategy and the economic vitality of the Choapa Province.

Africa holds immense untapped mineral wealth. Botswana offers political stability and growing mining infrastructure, while the Democratic Republic of the Congo is rich in high-grade copper and cobalt—critical for the global energy transition and battery technologies.
Next-Generation Polymetallic Operation
Tataki Mine, located in Botswana, is currently being transformed into one of Africa’s most advanced and sustainable polymetallic mining operations. After eight years in liquidation, the asset is now undergoing full-scale revitalization by Tataki Mining Company, part of GCR, with a focus on technological innovation, environmental responsibility, and lasting local impact.
With over 120 million tonnes of nickel-, copper-, and cobalt-rich ore and tails, Tataki is well positioned as a major supplier of critical minerals essential to the global energy transition. Work is actively progressing at the Phoenix Pit, targeting 40 million tonnes of run-of-mine (ROM) material, alongside the reprocessing of more than 80 million tonnes of surface stockpiles.
Built for sustainability, Tataki operates using renewable energy, biodegradable reagents like glycine, and a growing fleet of electric mining vehicles. Its modular plant design and strong environmental safeguards establish a new standard for responsible mining on the continent.
