Argentina's US$1 Billion Lithium Push and Chile's Fresh Drilling Campaigns Open a New Window for Exploration Equipment

On 28 October 2026, at Salar del Hombre Muerto in Catamarca Province, northwestern Argentina, Rio Tinto chief executive Simon Trott stood before two newly inaugurated lithium plants and confirmed that the Anglo-Australian miner is evaluating a further US$1 billion lithium facility at the same salt flat. Only days earlier, on 27 October, Chile's state copper company Codelco and BHP signed the Anillo copper exploration agreement in the Antofagasta region, committing up to US$40 million to early-stage geological studies and drilling. Within a single week, the two pillars of South America's mining economy — Argentine lithium and Chilean copper — both sent the same signal: a new wave of exploration and construction is about to roll across the continent, and it will be drilled, bolted and powered into existence piece by piece.

I. A Policy-Driven Investment Wave: Argentina's RIGI Regime Changes the Math

The project Rio Tinto is weighing, an expansion of its Fénix operations at Salar del Hombre Muerto, would be submitted to Argentina's RIGI — the Incentive Regime for Large Investments — with a final investment decision possible by the end of the decade. Rio Tinto already holds roughly US$4.4 billion in committed and pipeline investments across Argentina, and its board is scheduled to review South American capital allocation on 15 December. The company's two plants inaugurated in late October add fresh processing capacity in the heart of the "lithium triangle", where Argentina, Bolivia and Chile together hold about 60% of the world's lithium resources.

Rio Tinto is not alone. First Quantum Minerals has said it intends to apply for RIGI treatment before the end of 2026 for its Taca Taca copper project in Salta Province — a development of up to US$5.25 billion that would produce an average of roughly 209,000 tonnes of copper per year over a 35-year mine life. For a country that spent much of the past decade starved of mining capital, the speed at which global majors are now lining up marks a genuine regime change, driven by tax incentives, exchange-rate reforms and a government in Buenos Aires that has made resource development a centrepiece of its economic programme.

II. Chile Answers with Drilling: New Campaigns Across the Copper Belt

Chile, meanwhile, is proving that brownfield expansion and grassroots exploration are accelerating in parallel. The Codelco–BHP Anillo agreement covers an early-stage project in the Antofagasta region where geological research and drilling will be carried out to assess future development potential. Further south on Chile's coastal belt, the La Verde porphyry copper project has now surpassed 35,000 metres of cumulative drilling, with wide, near-surface intersections prompting the operator to fold the deposit into a pre-feasibility study and target a first resource estimate before the end of the year. Environmental assessment is planned for next year, with production envisioned around 2031.

The pipeline does not stop there. The Sierra Gorda copper expansion — a US$725 million joint undertaking — broke ground in October and is expected to lift annual output to 195,000 tonnes by the second half of 2030. In Peru, Glencore completed land agreements for the Coroccohuayco project, an approximately US$1.8 billion expansion of its Antapaccay operation targeting startup in the second half of 2029. Taken together, these projects imply thousands of kilometres of core drilling, vast volumes of benching and haul-road construction, and sustained demand for reliable drilling and support equipment across the Atacama and the Andes.

III. What the Boom Means for Drilling and Support Equipment

Exploration booms of this kind translate directly into equipment demand. Mineral exploration in South America depends on surface and mobile drilling rigs capable of operating at altitude, in dust, over long distances between remote sites — conditions that punish fragile machinery and reward robust, complete, easy-to-service packages. As projects move from exploration to feasibility and construction, operators also need dependable on-site power: remote drill camps, dewatering pumps, workshops and worker facilities all run on generator sets, and containerized units that can be trucked to site and commissioned quickly are at a premium.

Water logistics add a further layer. Drilling programmes in arid regions consume significant volumes of water for circulation and dust suppression, and many operators in Chile and Argentina rely on dedicated water wells rather than strained municipal networks. Vehicle-mounted water well drilling rigs that can move quickly between sites and complete boreholes in hard rock are increasingly treated as core exploration-support assets rather than optional extras. Suppliers able to combine drilling rigs, containerized power and pressure-vessel and storage equipment into coordinated packages — and to support them across the Southern Hemisphere — are positioned to ride this cycle.

IV. Zhongzhen Meihua: Ready for the South American Cycle

Jiangsu Zhongzhen Meihua Intelligent Equipment Co., Ltd. has been building exactly this kind of capability. The company manufactures complete mine drilling equipment, vehicle-mounted water well drilling rigs and containerized generator sets, alongside hydrogen storage pressure vessels and environmental protection equipment, and has been steadily expanding its footprint in South America and Oceania — the very regions now entering an investment upswing. As Argentine lithium and Chilean copper projects convert policy momentum into metres drilled, Zhongzhen Meihua stands ready to equip exploration teams and mine builders with proven, field-ready equipment for the continent's next great resource cycle.
