India-US Trade Deal Is "Within Reach" — But the Real Play Is in Critical Minerals, Not Tariffs

India-US Trade Deal Is "Within Reach" — But the Real Play Is in Critical Minerals, Not Tariffs

The India-US trade deal dominated headlines this weekend as Secretary Rubio's India visit signalled a "strategic reset" between the two countries. Multiple reports confirmed the interim trade pact is close to being sealed, with both sides pushing to finalize terms.

But here's what most investors are missing: the deal has shifted far beyond simple tariff reductions. The centrepiece of the new India-US partnership is supply chain security and critical minerals — tungsten, rare earth elements, lithium, cobalt, and high-purity quartz. These are the materials that power EVs, wind turbines, defence equipment, and semiconductors. And India has them.

For decades, China has dominated 60-70% of global rare earth processing. The US wants alternatives. India wants to monetize its deposits. This isn't trade diplomacy — it's industrial strategy. And a handful of Indian companies are positioned to capture this structural shift.

Hindustan Zinc: The First Mover in Rare Earths

Hindustan Zinc (HINDZINC) has already secured Letter of Intent for three critical mineral blocks: a Tungsten block in Andhra Pradesh (308 hectares, 0.07 million tonnes of resources), a Potash block in Rajasthan (1,841 hectares, 18.07 million tonnes), and a Rare Earth Elements block in Uttar Pradesh (201 hectares, 0.182 million tonnes), per their Q3 FY26 investor presentation.

The company is "likely the first private company in India to secure a rare earth monazite block — a land-based, non-radioactive deposit," as stated in their Q1 FY26 earnings call. They're also pursuing copper, lithium, nickel, cobalt, neodymium, antimony, graphite, and germanium.

The financials back the ambition: Q3 FY26 delivered revenue of Rs 10,980 crore (up 27% YoY), EBITDA of Rs 6,087 crore (up 34% YoY), and PAT of Rs 3,916 crore (up 46% YoY) with an EBITDA margin near 55%. This cash generation funds their critical minerals pivot without needing external capital.

Midwest Limited: Quartz and Rare Earths

Midwest Limited (MIDWESTLTD), India's largest integrated quartz processor, is diversifying into heavy mineral sands and rare earth minerals. Per their investor presentation, they commissioned Phase I of a 303,600 MTPA quartz processing plant in September 2025 serving the solar glass and engineered stone sectors, with plans to double capacity to 606,600 MTPA for Ultra-High-Purity Quartz — a critical input for semiconductors.

They've also secured four exploration licenses in Sri Lanka for Rutile, Ilmenite, Zircon, Garnet, Sillimanite, and Monazite — key feedstocks for titanium dioxide, pigments, and rare earth elements used in EVs, renewables, and defence.

Financially, Q2 FY26 showed revenue of Rs 158.69 crore (up 12% YoY) with EBITDA surging 52% to Rs 46.53 crore, pushing EBITDA margin to 29.3%. The company operates across 17 countries with over four decades of mining expertise.

GMDC: Government-Backed Rare Earth Deposits

Gujarat Mineral Development Corporation (GMDCLTD) holds the Ambadungar deposits, described in their annual report as "rich in light rare earth elements (LREEs)" that will be processed to produce a mixed rare earth concentrate. Their reserves of 7.3 million tonnes contain Copper, Lead, Zinc, and trace elements including Silver, Cadmium, Germanium, and Selenium.

GMDC has partnered with TEXMiN at IIT (ISM) Dhanbad to implement mining solutions for critical mineral development, and with Monash University to enhance research in India's mining sector. As a state government entity, they're a natural partner for the National Critical Mineral Mission (NCMM).

NALCO: Aluminium as Strategic Metal

National Aluminium Company (NATIONALUM) benefits from aluminium's classification as a strategic/critical mineral for clean energy. Indian aluminium consumption has been growing at a CAGR of approximately 9% over the last five years, per their annual report. With the US seeking non-Chinese aluminium supply chains, NALCO's integrated mine-to-metal operations position it as a potential beneficiary of any bilateral supply agreement.

The Structural Tailwind

India's National Critical Mineral Mission plans to auction 24 critical mineral blocks — Lithium, Cobalt, Tungsten, REEs, Potash — aiming to support clean energy, electronics, EVs, and defence. The India-US deal provides a guaranteed buyer for what comes out of these mines, transforming a domestic mining push into an export opportunity.

Defence exports have already hit an all-time high of Rs 23,622 crore in FY25, per industry filings. Critical minerals feed directly into this: tungsten for defence equipment, rare earths for precision-guided systems, and high-purity quartz for electronics.

What Retail Investors Should Do

This is not a trade that plays out in quarters — it's a multi-year structural shift. The companies above are at different stages: Hindustan Zinc has the financial muscle and has already secured blocks; Midwest is expanding capacity; GMDC holds deposits but is earlier-stage.

Investors should watch for: (1) actual mining commencement timelines at the critical mineral blocks, (2) any bilateral supply agreements announced as part of the India-US deal, and (3) NCMM auction results for new block allocations. The risk is execution — securing a block and commercially mining it are very different things. But with US strategic interest providing both demand certainty and potential technology transfer, the risk-reward tilts favourably for patient capital.
