Argentina–US Strategic Framework for Critical Minerals Supply Chains (FORGE founding bilateral)

Mechanism

A bilateral strategic framework signed at the inaugural FORGE Critical Minerals Ministerial establishing that Argentina and the United States will:

• Cooperate on the full supply-chain from exploration, mining, and

processing through refining and value-added manufacturing in the critical-minerals sector.

• Promote a safe, resilient, and competitive supply of critical minerals

through long-term investment facilitation, removing barriers to FDI, and creating an environment favourable to sustained minerals development.

• Coordinate on supply-chain transparency, environmental standards, and

responsible-resource governance — the standard FORGE founding-bilateral template language, with Argentina-specific context around the post-Kirchner mining-investment reform stack (RIGI, Decreto 449, Decreto 563, and Banco Central FX liberalisation).

• Aim to consolidate more solid and diversified critical-mineral value chains

to meet increasing global demand — language that directly mirrors the US strategic framing around reducing dependence on Chinese-dominated refining and processing capacity.

The framework is one of eleven founding bilateral instruments signed simultaneously at the FORGE ministerial on 4 February 2026, alongside Cook Islands, Ecuador, Guinea, Morocco, Paraguay, Peru, Philippines, UAE, UK, and Uzbekistan. The ministerial convened 55 delegations, including representatives of the European Commission.

Why Argentina is the lithium-centrepiece of the Latin-American FORGE cohort

Argentina holds the fourth-largest lithium reserves globally (approximately 19.6 Mt LCE as of 2025 USGS estimate — behind Chile, Australia, and Bolivia but ahead of the US, China, and all other producers). It sits at the southern apex of the "Lithium Triangle" (Argentina–Chile–Bolivia) which together holds roughly 58% of world reserves.

Key Argentine lithium assets relevant to this framework:

• Cauchari-Olaroz (Jujuy province): ~40,000 t/yr LCE capacity ramp; Ganfeng

(Lithium Americas spin-off / Allkem legacy asset) → now Arcadium Lithium post-Allkem–Livent merger.

• Rincon (Salta): Rio Tinto USD 825m direct lithium extraction (DLE)

project; production ramp expected 2026–2027.

• Sal de Vida (Catamarca): Allkem / Arcadium Lithium brine operation.
• POSCO Argentina (Salta): Korean state-linked DLE project.
• Multiple early-stage brine and hard-rock prospects across Jujuy, Salta,

Catamarca, San Juan, and La Rioja under the RIGI / Decreto 449 simplified licensing framework.

On copper, Argentina is an emerging producer (not yet a top-10 country) but with significant exploration-stage assets: Josemaría (Lundin Mining, San Juan, ~140 kt/yr Cu in concentrate design), Filo del Sol (Lundin / BHP JV), Altar (Regulus Resources / AIM). The framework's copper commitment is forward-looking — oriented toward channelling US-aligned project finance toward assets that could reach production in the 2028–2035 window.

Policy coherence stack

This framework is the demand-side anchor of a coherent Argentine supply-chain architecture that has been assembled in layers since 2023:

The bilateral minerals framework materially strengthens the RIGI/Super RIGI investment-attractiveness case by providing US sovereign-level demand-side backing — a signal to third-party financiers (DFC, EXIM, private-equity) that Argentine lithium and copper assets have a committed US-government counterparty, reducing sovereign-risk discount.

Trump-Milei alignment context

The framework sits at the intersection of two mutually reinforcing strategic postures: (a) the Trump administration's determination to de-risk US critical-minerals supply chains from Chinese-dominated processing (the FORGE architecture at macro level) and (b) the Milei administration's strategic decision to position Argentina explicitly within the US-aligned global economic order, differentiating from the Kirchner-era BRICS-adjacent posture and Bolivia's MAS-anchored lithium-nationalism.

This alignment gives the framework a geopolitical durability that a purely commercial instrument would lack. However, Argentina's electoral cycle is the principal execution risk: midterm legislative elections are scheduled for October 2026 and Milei's coalition hold on the Chamber of Deputies is narrow; full presidential elections follow in 2027.

Why severity 3

• Argentina is a top-4 global lithium reserves holder and the RIGI +

Decreto 563 zero-export-duty package has made it structurally the most FDI-accessible lithium jurisdiction in the Lithium Triangle.

• The bilateral instrument is non-binding — no DFC or EXIM Project Vault

Heads of Terms instrument has been published for Argentina as of the filing date, in contrast to the Uzbekistan track (which had follow-on DFC financing announced within 14 days of FORGE).

• Severity held at 3 (vs. 4 for FORGE itself) because the framework lacks

a specific financial commitment amount. Severity could rise to 4 if a US-financed lithium-processing facility or DLE technology-transfer project is announced under the FORGE umbrella, or if Argentina is brought into the EXIM Project Vault strategic stockpile mechanism.

Downstream implications

• Lithium-price dynamics. Argentine brine-lithium production economics

are highly sensitive to spot prices (unlike hard-rock spodumene which has higher operating leverage). The US-demand-side anchor could accelerate project-financing timelines for Rincon (RIO) and Josemaría (Lundin), adding to supply in the 2027–2030 window.

• China exposure. Argentine lithium projects have historically attracted

significant Chinese state capital (Ganfeng at Cauchari-Olaroz, CATL prospecting activity). The FORGE alignment creates a competitive dynamic for future project-financing rounds where US-aligned DFC/EXIM terms compete with Chinese SDB/CDB lending — but does not unwind existing Chinese concession positions.

• Latin-American FORGE cohort. Argentina (lithium/copper), Peru (copper),

Ecuador (copper/gold), and Paraguay (titanium/rare earths exploration) form the Latin-American bloc of the eleven FORGE founding bilaterals. Notably absent: Chile (world's #1 copper + #2 lithium, but Boric government's multilateral-framework preference), Brazil (rare earths / niobium, Lula's BRICS-aligned posture), and Bolivia (world's #1 lithium reserves, MAS-era state-nationalism).

• Environmental commitments. The framework includes Argentine commitments

to combat illegal logging and promote resource-efficiency — standard FORGE template language but notable in the context of Argentina's Glacier Law reform debate (Ley 27804 filed 2026-04-24) which critics argue weakens high-altitude water-table protections relevant to brine-lithium operations.

Open questions

• Will a DFC + EXIM Heads of Terms instrument follow for a specific Argentine

lithium or copper project?

• Does the framework intersect with the USD 825m Rio Tinto Rincon project

timeline? RIO's DLE technology is of direct interest to the DOE's critical-minerals strategy.

• How does the framework survive the October 2026 midterm elections and

potential 2027 presidential cycle? The Peronist opposition has been publicly sceptical of RIGI-class mining-investment incentives.

• Is lithium processing and battery-precursor manufacturing explicitly

within scope, or limited to upstream mining and concentrate? The difference matters materially for supply-chain localisation vs. raw-export economics.

• What is the interaction with the US-Argentina ARTIA (Reciprocal Trade and

Investment Agreement framework, signed 2026-02-05) — are the two instruments complementary channels or is one meant to supersede the other for minerals?
