Here are 6 junior ASX resources companies that have partnerships with major miners!

It is always tough for junior ASX resources companies to realise their ultimate ambitions. There might be short-term jumps from favourable commodity price movements, drilling results or the results of scoping or feasibility studies. But one of these milestones is a partnership with a major miner and this could be particularly important whether as a cornerstone investor, joint venture partner or offtake dealer.

These arrangements allow juniors to advance projects faster and more capital-efficiently than the traditional model of serial capital raisings alone. It also signals that an informed industry participant, with their own technical teams and commercial interests, has looked closely at the asset and decided it is worth backing. Let’s look at 6 companies in such a fortunate position.

6 junior ASX resources companies that have partnerships with major miners!

1. OzAurum Resources (ASX: OZM)

In late January 2026, gold junior OzAurum Resources secured a $4.1m placement to fellow Western Australian gold explorer Forrestania Resources (ASX:FRS). Forrestania subscribed for 56.9 million new shares at $0.072 each to emerge as a 19.9% cornerstone shareholder.

The deal is more than just a capital injection. Forrestania, which has been building a portfolio of gold assets and processing infrastructure across the Eastern Goldfields at pace, brings processing know-how and regional credibility to OzAurum’s register. OzAurum’s flagship asset is the Mulgabbie North Gold Project, located along the Relief Shear adjacent to Northern Star Resources‘ (ASX:NST) Carosue Dam operation — a geological address that speaks for itself. The placement funds are earmarked for a heap leach feasibility study and early mine development work.

OzAurum has since received environmental approval from the WA government for Stage 1 open-pit mining and heap leach operations, and has acquired a refurbished processing plant for just $20,000, keeping capex exceptionally light. Environmental approval being in hand, the project now has a clear line of sight to production, even if at a speculative stage.

2. New Murchison Gold (ASX: NMG)

If OzAurum represents the early stages of a major-backed junior, New Murchison Gold is further along the track. The company, formerly Ora Gold, relisted under a new name and strategy in late 2024, has a binding ore purchase agreement with Westgold Resources (ASX:WGX), a mid-tier Australian gold producer with multiple processing hubs across Western Australia.

Under the arrangement, NMG mines ore from its Crown Prince gold deposit in the Murchison region near Meekatharra and trucks it 36 kilometres to Westgold’s Bluebird processing facility for treatment. Monthly delivery caps sit at 30,000 to 50,000 tonnes. By late 2025, Crown Prince had already delivered three strong months of production, with one month’s ore sales generating $41.6m for NMG, a striking figure for a company that was still an explorer not long ago.

The feasibility study underpinning Crown Prince outlines pre-tax cashflow of $226m over 30 months at prevailing gold prices, and NMG has flagged it is consistently meeting or exceeding its feasibility estimates. The Westgold alliance eliminates the need for NMG to build its own processing infrastructure, slashing capital intensity and time-to-cashflow in one move. This kind of tolling arrangement is increasingly favoured by juniors looking to monetise high-grade deposits quickly.

3. Medallion Metals (ASX: MM8)

Medallion Metals has constructed one of the more creative junior-major partnerships on the ASX. The company is advancing its Ravensthorpe Gold Project in Western Australia’s southern Goldfields, a high-grade gold and copper deposit centred on the historic Kundip Mining Centre with a mineral resource of roughly 1.6Moz gold equivalent. The challenge for Medallion was always the capital cost of building processing infrastructure from scratch.

The solution came via a binding agreement, completed in August 2025, with IGO (ASX:IGO) to acquire IGO’s Forrestania Nickel Operations. This includes the Cosmic Boy concentrator, a proven processing plant that IGO no longer needs following the wind-down of nickel mining amid depressed prices. Under the transaction structure, Medallion assumes rehabilitation liabilities and grants IGO a 1.5% net smelter return royalty on gold production from the tenements, with no upfront cash.

Medallion has since received EPBC environmental approval for the underground mining and processing strategy, clearing a major hurdle. The deal pairs Medallion’s established high-grade resource with ready-made infrastructure, reducing development capital, permitting complexity, and time to first production significantly. Commodity trading giant Trafigura has also entered the picture, offering up to US$50m in prepayment financing alongside seven-year offtakes over copper and precious metal concentrates.

4. Alchemy Resources (ASX:ALY)

Alchemy Resources is a micro-cap explorer that has quietly assembled a diverse portfolio of joint ventures with some well-credentialled names. Chief among them is Northern Star Resources (ASX:NST) — Australia’s largest domestic gold miner, which holds approximately 6.6% of Alchemy’s register, making it the company’s largest shareholder. NST’s presence on the register provides a powerful signal of project quality and geology, given that Northern Star commands significant ground in the same Eastern Goldfields belts where Alchemy operates near Lake Rebecca.

But Alchemy’s partnership story extends further. At its Karonie lithium project east of Kalgoorlie, the Japan Organization for Metals and Energy Security or JOGMEC is spending $6 million over five years to earn a 51% stake. For those who didn’t know, JOGMEC is the strategic minerals body that helped back rare earths giant Lynas Rare Earths (ASX:LYC) in its formative years.

Alchemy also holds minority positions in projects through JVs with Catalyst Metals (ASX:CYL) and Bill Beament’s Develop Global (ASX:DVP). Having multiple assets simultaneously funded by JV partners gives Alchemy unusual runway for its size.

5. Kali Metals (ASX:KM1)

Kali Metals is a lithium-focused resources junior that listed on the ASX in January 2024 following a spin-out of assets from Kalamazoo Resources and Canada’s Karora Resources. The company holds roughly 3,960sqkm of exploration tenure across the Pilbara, Eastern Yilgarn, and Lachlan Fold Belt, with a focus on hard-rock lithium.

Two of Kali’s three Pilbara lithium projects, DOM’s Hill and Marble Bar, are fully funded by SQM, the Chilean chemical and lithium giant that ranks among the world’s largest lithium producers. Under an earn-in agreement inherited from Kalamazoo, SQM covers all exploration costs on these two projects in exchange for a path to a majority interest.

For a small explorer, full funding from one of the global industry’s heavyweights is a meaningful structural advantage: it preserves Kali’s cash for its self-operated assets while keeping its Pilbara ground active and advancing. Mineral Resources (ASX:MIN) also emerged as a near-10% shareholder shortly after listing, drawn to the project’s strategic positioning adjacent to some of WA’s largest spodumene operations.

6. Challenger Gold (ASX:CEL)

Challenger Gold is advancing the Hualilan gold project in Argentina’s San Juan province, a 2.8Moz gold-equivalent deposit with high-grade open-pit and underground components. The project has long been well-regarded on technical merits, but Argentina’s sovereign risk profile has kept some investors on the sidelines.

To accelerate the path to cash flow without shouldering the full capital burden of a processing facility, Challenger locked in a three-year toll milling agreement with Casposo Argentina Mining, a subsidiary of Austral Gold (ASX:AGD), for 150,000tpa of processing capacity, with total contracted capacity of 450,000t. The deal also provides working capital support for mining, trucking, and processing until operations start generating revenue, giving Challenger a funded runway into production.

By piggybacking on Austral’s established Argentine processing infrastructure, Challenger sidesteps one of the hardest and most capital-intensive parts of bringing a new mine into production. This structure allows the company to monetise the high-grade, near-surface portion of Hualilan first, generating early cash flow while the wider project continues to be derisked.
