BHP Targets Zambia’s Untapped Copper Potential as Exploration Strategy Shifts

Global mining giant BHP is stepping up its interest in large-scale copper exploration in Zambia, signalling renewed confidence in the country’s mineral potential as global demand for the metal accelerates.

According to Zambia’s mines ministry, the company is exploring opportunities to identify major copper deposits that remain undiscovered due to their depth or geological complexity.

Renewed focus on Africa’s copper belt

Zambia, Africa’s second-largest copper producer after the Democratic Republic of Congo, is aiming to more than triple its copper output by 2031. To achieve this, the government is actively promoting investment into underexplored regions and modernising its geological data systems.

The renewed engagement from BHP marks a notable shift. The company has largely maintained a limited presence in Africa since spinning off its South African assets into South32 in 2015. Its recent moves suggest a more strategic re-entry, driven by the global race for critical minerals.

Technology-driven exploration

BHP’s exploration strategy reflects a broader industry shift toward advanced, data-led discovery methods.

Speaking in Lusaka, Campbell McCuaig, BHP’s head of global generative exploration, highlighted that many of the world’s remaining large copper deposits are no longer easily accessible.

“Many of the remaining large deposits are either deeply buried or hidden beneath geological cover,” he said.

To address this, BHP is deploying sophisticated geological modelling and large-scale data analysis to identify “mineral systems” — the underlying processes that form major ore deposits — rather than relying solely on traditional surface exploration.

Zambia’s reforms attract investor attention

Zambia’s efforts to digitise geological records and conduct airborne geophysical surveys are playing a key role in attracting interest from global miners.

Improved access to reliable geoscience data reduces exploration risk and enhances the country’s appeal as a destination for long-term mining investment.

McCuaig noted that these reforms are critical in enabling companies like BHP to apply advanced exploration techniques more effectively.

Strategic timing amid global copper demand

BHP’s renewed interest comes at a time when copper is increasingly viewed as a cornerstone of the global energy transition. The metal is essential for renewable energy systems, electric vehicles, and grid infrastructure.

As demand rises, mining companies are under pressure to secure new supply sources — particularly large, high-quality deposits capable of supporting long-term production.

Outlook

While BHP has not yet committed to developing new mines in Zambia, its growing exploration activity signals confidence in the region’s geological potential.

For Zambia, the challenge will be converting this renewed interest into sustained investment and production growth, ensuring that reforms translate into tangible economic gains.

As the global search for copper intensifies, the country is positioning itself as a key player in the next phase of the mining cycle.
