BHP Group is one of the largest diversified mining companies in the world and a major player in the global copper industry. With operations spread across continents, BHP’s copper assets are primarily located in Chile (Escondida) and South Australia (Olympic Dam).

The company produces millions of tonnes of copper annually, making it a cornerstone supplier to industries that rely heavily on the metal such as renewable energy, electric vehicles and construction. But only in the last 12 months has it become the company's biggest earner, delivering 51% of its 1H26 profit which came in at US$5.6bn.

BHP’s scale and diversification across commodities like iron ore, coal and petroleum make it a relatively stable investment compared with smaller mining firms.  BHP offers strong dividends, robust cash flow and ongoing investment in future-facing commodities for investors seeking a reliable copper stock with global reach and consistent performance.

The company offers both existing mines which count amongst the world's largest, as well as new ones coming online. Investors should be particularly excited about its Vicuna project in Argentina that could be one of the world's top 5 copper mines and may even come for free as the cost of mining copper could be covered by the gold and silver resource.

Sandfire Resources is a mid-tier Australian mining company specialising in copper production, with a strong reputation for operational efficiency and high-grade assets. The company first gained attention with its DeGrussa Copper–Gold Mine in Western Australia, which became one of the country’s premier copper operations. While DeGrussa has now transitioned to closure, Sandfire has strategically expanded its global footprint, most notably through the acquisition of the MATSA Mining Complex in Spain.

This acquisition has significantly bolstered the company’s production capacity and diversified its asset base. Sandfire also has interests in the Motheo Copper Mine in Botswana, further positioning the company as a key player in emerging copper-rich regions. Unlike larger miners, Sandfire offers investors more direct leverage to copper prices due to its concentrated commodity focus. With copper being vital to electrification, battery production and renewable-energy infrastructure, Sandfire is well-placed to benefit from future demand surges. The company also places a strong emphasis on responsible mining practices and sustainability, aligning with evolving investor expectations.

In the most recent set of results, 1H26, the company achieved a half-year revenue record and more than doubled its underlying earnings, both due to improved operations at MATSA and momentum in copper prices. It went from a $288m net debt position to $13m net cash. It has guided to 149-169kt for the full year.

Alma Resources has 51% of the Briggs Project in Queensland. Briggs boasts >2Mt copper, making it one of Australia's largest undeveloped copper deposits. Alma has rallied in recent months due to successful exploration as well as momentum in the copper market.

Briggs is in an ideal location, located around 50 km west of Gladstone, covers 225km² over six EPMs. It has road, rail, power and gas pipelines all within 15km. The company plans for a localised workforce, and to export concentrate via the Port of Gladstone which is just 60km away.

Following the completion of a Scoping Study in 2025, the Board has resolved to progress directly to a Pre-Feasibility Study (PFS). Investors can expect ongoing drilling updates alongside the transition to PFS, marking a significant step toward defining the Brigg’s development pathway.
