What IRIS Metals does

IRIS Metals (ASX:IR1; legal entity Iris Metals Pty Ltd) is an Australian-listed exploration and development company focused on US critical minerals. Founded in 2022 when it pivoted from Australian-focused exploration through the acquisition of White Rock LLC, the company holds a portfolio of hard-rock lithium, rubidium, and tungsten projects in mining-friendly US jurisdictions. The flagship is the Beecher Lithium-Rubidium Project in the Black Hills of South Dakota, supported by a 3.03M tonne JORC resource at 1% Li2O and 0.116% Rb2O — the first US mineral resource to specifically quantify rubidium. Adjacent projects include Tin Mountain, Edison, and Ingersoll (also in the Black Hills), plus the Finley Basin Tungsten Project in Montana, representing diversification across lithium, rubidium, tungsten, beryllium, cesium, and tantalum from the same pegmatite systems.

The company operates a hub-and-spoke production architecture: centralised processing infrastructure fed by multiple permitted brownfield mine sites within its 2,056 claims covering approximately 171 sq km of Black Hills landholding. Technology centres on conventional hard-rock spodumene mining and Western Australian-style processing, deliberately avoiding experimental DLE or clay extraction methods. A 2024 metallurgical milestone — successful conversion of 6% spodumene concentrate to 99.5% battery-grade lithium carbonate in partnership with US-based ReElement Technologies — established a domestic conversion pathway. Additional partnerships cover offtake exclusivity (Stardust Power), processing collaboration (Rock Zero), and US capital markets access (Roth Capital Partners for a planned Nasdaq or NYSE dual-listing).

The business model is pre-revenue: revenue streams are planned across spodumene concentrate sales, battery-grade lithium carbonate/hydroxide via ReElement, and future rubidium and tungsten sales to defense, technology, and industrial buyers. The company is explicitly positioned as a domestic supply solution for US critical minerals import dependency — the US currently imports 100% of its lithium requirements. Pricing is not publicly disclosed; market references cite SC6 spodumene around US$900/t and lithium carbonate around US$15,000/t. Customer segments are vertical — battery/EV manufacturers, defense and technology sector buyers, and defense/industrial manufacturers — with no named customers yet and the first commercial DSO sales from Beecher targeted in the near term using proceeds of the February 2026 A$5.5M placement. The company has 1-10 employees, a market cap of A$32.39M as of September 2025, and intends to dual-list on a US exchange.

Core offering

IRIS Metals is a U.S.-focused critical minerals exploration and development company that acquires, explores, and develops hard rock lithium, rubidium, and tungsten mining projects in mining-friendly U.S. jurisdictions (primarily South Dakota's Black Hills and Montana). The company's planned commercial outputs include direct shipping ore (DSO) and spodumene concentrate sales to lithium processors, conversion to 99.5% battery-grade lithium carbonate via ReElement Technologies, and future production of rubidium and tungsten for defense, technology, and industrial buyers.

Product overview

IRIS Metals is a U.S.-focused critical minerals explorer and developer offering a portfolio of mining projects rather than a software product. The company's core assets include the flagship Beecher Lithium-Rubidium Project (lithium and rubidium), Tin Mountain Project, Edison Project, and Ingersoll Project (all lithium-focused in South Dakota), plus the Finley Basin Tungsten Project in Montana. The company employs a hub-and-spoke model, developing multiple mine sites to feed centralized processing infrastructure, with processing partnerships for converting spodumene concentrate to battery-grade lithium carbonate.

Products and services

• Beecher Lithium-Rubidium Project Flagship mining project in South Dakota's Black Hills combining an established JORC lithium resource with world-class high-grade rubidium mineralisation in pegmatites. Total resource of 3.03M tonnes averaging 1% Li2O and 0.116% Rb2O. Produces spodumene concentrate and is targeted for battery-grade lithium carbonate and rubidium sales.
• Finley Basin Tungsten Project High-grade tungsten project in Granite County, Montana covering 378ha of unpatented mining claims in the Flint Creek Mountain Range. Historical non-JORC resource of 850,000 tonnes at 0.68% WO3 from Union Carbide's work in the late 1970s-early 1980s. Target output is tungsten for defense applications, cutting tools, and industrial manufacturing.
• Tin Mountain Project Lithium project in South Dakota with historic spodumene mining. Expanded to include the 752-hectare Tin Mountain Extension (TME). Contains high-grade lithium and caesium mineralisation.
• Edison Project South Dakota lithium project including historic Edison Mine once owned by Thomas Edison. Phase I drilling returned exceptional 3.30% Li2O intercepts.
• Ingersoll Project Acquired project covering historically significant Bob Ingersoll lithium and beryllium mine near Keystone, South Dakota. Adds 12.2 hectares of private land with 87 federal mining claims.
