China’s Argentina mining footprint: ownership-weighted reality for project teams

30 Second Briefing
China’s share of Argentina’s approved mining investment under the RIGI scheme is just 9.2%, or about $1.95 billion of $21.2 billion across 12 projects, once Chinese equity stakes in assets such as Tres Quebradas, Cauchari-Olaroz and Veladero are ownership-weighted. Plusmining’s analysis contrasts this with claims that Chinese firms control 70% of planned lithium output, noting that figure is based on announced capacity, including projects still awaiting approval. If the $3 billion, 67%-Ganfeng-owned Pozuelos-Pastos Grandes and two other lithium schemes are approved, China’s ownership-weighted share could rise to 22.3%, while major copper projects backed by BHP, Lundin and Glencore currently show no direct Chinese equity.
Technical Brief
- Plusmining’s ownership-weighting multiplies each project’s RIGI-approved capex by Chinese equity percentages through all holding layers.
- Six of 12 approved mining projects show Chinese exposure, but only Tres Quebradas, Cauchari-Olaroz expansion and Veladero phases 8–9 have direct Chinese shareholders.
- Zijin controls Tres Quebradas via Neo Lithium in Catamarca, giving full attribution of that project’s approved spend.
- Ganfeng’s 46.7% stake in the Cauchari-Olaroz expansion and Shandong Gold’s 50% of Veladero phases 8–9 drive most direct Chinese lithium and gold exposure.
- Indirect exposure arises from Chinalco’s ~11.23% in Rio Tinto, cascading into Rincón and Fénix lithium, and only ~1.8% into Los Azules via Nuton–McEwen Copper.
- A binary “any Chinese participation = 100% attributed” test still yields a footprint well below the 70% capacity-based claim.
- Three pending lithium projects under RIGI—Pozuelos-Pastos Grandes, Salar de Jama and Litio Ángeles—represent ~222,000 t/y of proposed capacity and US$4.9 billion capex.
- Chinese-backed lithium pipeline totals ~307,000 t/y announced capacity, of which only 85,000 t/y sits in already-approved projects.
- Several approved projects, including Rincón and Fénix, lack disclosed nameplate capacities, preventing robust independent verification of percentage-of-output claims.
- For strategic planning, the analysis separates equity exposure, operational control and offtake/processing agreements as distinct levers of Chinese influence over Argentine critical minerals.
Our Take
Plusmining’s role in this Argentina analysis echoes its work in the copper-price assumptions review from April 2026, signalling that the same Chile-based consultancy is increasingly shaping how long-term copper and lithium economics are framed across Latin American projects.
With lithium and copper both flagged as ‘battery metals’ in our database and featuring heavily in the 94 keyword-matched pieces, the relatively modest 9.2% Chinese share of RIGI-approved mining capex suggests ample room for non-Chinese players such as BHP, Lundin Mining and Glencore to scale exposure in Argentina’s critical minerals build-out.
