Sandfire Resources Unveils Maiden Resource at A1, Boosting Motheo Hub Potential

Key Take Away: Sandfire Resources (ASX: SFR) has reported a maiden Inferred Mineral Resource estimate for its A1 Copper-Silver Deposit in Botswana. The resource, located 20km from the company’s Motheo Copper Mine, contains 5.6 million tonnes at 1.3% copper and 10 grams per tonne (g/t) silver, equating to 73,000 tonnes of contained copper and 2 million ounces of silver.

The A1 Deposit has the potential to become a satellite ore feed for Sandfire’s Motheo Production Hub, supplementing the nearby A4 Deposit. The maiden resource was based on the results of 75 holes drilled between 2022 and 2024, with the mineralization remaining open down-dip and along strike.

Sandfire Chief Executive Officer and Managing Director, Brendan Harris, commented: “We continue to prioritise exploration activity in the Iberian Pyrite and Kalahari Copper Belts to increase the life of our well capitalised and strategically positioned metal processing hubs, Motheo and MATSA. Today, we have confirmed an initial 5.6Mt resource for the A1 deposit, located 20km to the northeast of our Motheo processing facility. We see real potential for this resource to grow as we increase drillhole density and test the open extent of the orebody.”

The A1 Deposit is hosted within a folded sequence of sandstone, siltstone, shale, and carbonate units in the lower D’Kar Formation. Copper and silver mineralization occurs as coarse to semi-massive chalcopyrite, bornite, and chalcocite within quartz-carbonate veins, with additional disseminated copper sulphides along bedding planes and foliation.

Preliminary metallurgical test work on the A1 material has shown positive results, with recoveries in line with those achieved at the T3 deposit, which represents the existing Motheo processing plant flowsheet. Further comprehensive test work will be conducted as the project advances.

The global copper market is experiencing strong fundamentals, driven by the increasing demand for the metal in renewable energy technologies, electric vehicles, and infrastructure. As the world transitions towards a low-carbon economy, the need for copper is expected to grow significantly. This trend is further supported by the ongoing urbanization and industrialization of developing countries.

Sandfire Resources, with its expanding copper portfolio in the Kalahari Copper Belt and the Iberian Pyrite Belt, is well-positioned to benefit from these megatrends. The company’s focus on exploration and development of new copper resources, such as the A1 Deposit, alongside its existing production assets, could enable it to meet the growing demand for the metal.

As demand for copper continues to grow, driven by the global transition to renewable energy and electrification, new resources like A1 could play an important role in meeting future supply requirements. Sandfire’s success in delineating the maiden resource highlights the exploration potential of the Kalahari Copper Belt and the company’s ability to leverage its existing infrastructure in the region to develop new deposits.
