Revenue model
- Lithium Carbonate/Hydroxide Sales: Primary revenue stream from selling lithium carbonate (technical-grade for first 3 years, then converted to battery-grade lithium hydroxide from year 4 onward). Production of approximately 24,500 tonnes per year of LCE during Years 1-25, increasing to approximately 27,800 tonnes per year of lithium hydroxide from year 3 onward. Revenue of approximately $607.3 million annually (Years 1-25).
- Boric Acid Sales: Secondary revenue stream from boric acid production - approximately 135,500 tonnes per year during Years 1-25. Boron accounts for approximately 30% of revenue, providing stable cash flows that help position Rhyolite Ridge at bottom of global lithium cost curve. Revenue of approximately $182.8 million annually (Years 1-25).
- Offtake Agreement Revenue: Binding offtake agreements with major customers including Ford Motor Company, Prime Planet Energy & Solutions (Toyota-Panasonic JV), EcoPro Innovation (7,000 tpa lithium), and Dragonfly Energy for lithium products. Boron offtake agreements with Dalian Jinma (105,000 tpa boric acid) and Kintamani Resources for distribution in Asia.

Ioneer product offering
Product offeringCore offering
Ioneer is a development-stage mining company developing the 100%-owned Rhyolite Ridge Lithium-Boron Project in Esmeralda County, Nevada. The project will mine and process ore on-site to produce technical-grade lithium carbonate (years 1-3), battery-grade lithium hydroxide (from year 3 onward), and boric acid as a co-product. The unique lithium-boron mineralogy enables co-production of both critical minerals from a single mining and processing flowsheet, positioning the project at the bottom of the global lithium cost curve.
Product overview
Ioneer is an Australian lithium-boron mining developer operating as a single-project company focused entirely on its 100%-owned Rhyolite Ridge Lithium-Boron Project in Nevada. The project is a permitted, construction-ready greenfield mining operation that extracts and processes ore on-site to produce three mineral products: (1) technical-grade lithium carbonate for years 1-3, (2) battery-grade lithium hydroxide from year 3 onward, and (3) boric acid as a co-product. The unique mineralogy at Rhyolite Ridge—recognized as the only known lithium-boron deposit in North America and one of just two such deposits globally—enables co-production of lithium and boron using a single mining and processing flowsheet, positioning the project at the bottom of the global lithium cost curve.

Products and services
- Rhyolite Ridge Lithium-Boron Project Ioneer's 100%-owned flagship mining project in Esmeralda County, Nevada. A permitted, construction-ready greenfield project that will mine and process both lithium and boron on-site, producing lithium carbonate, lithium hydroxide, and boric acid for batteries, semiconductors, and industrial applications.
- Lithium Carbonate Technical-grade lithium carbonate (99% purity) produced at Rhyolite Ridge through the vat leaching process using diluted sulphuric acid. For the first 3 years of operations, lithium carbonate will be sold as technical-grade product before being converted to lithium hydroxide from year 4 onward.
- Lithium Hydroxide Battery-grade lithium hydroxide (99.5% purity) produced on-site at Rhyolite Ridge from year 3 onward using the liming method. Converted from technical-grade lithium carbonate produced in the main plant, utilizing excess steam and power from the sulphuric acid plant. Targeted annual production of approximately 27,800 tonnes per year.
- Boric Acid Commercial-grade boric acid produced at Rhyolite Ridge through crystallization of the vat leach solution. The primary feedstock chemical for industry, used in over 100 specialist applications including borosilicate glass, fiberglass, LCD panels, permanent magnets, and ceramics.
Quantifiable outcome
- AISC of $4,628/t LCE (Years 1-25), placing Ioneer in lowest quartile for lithium production globally

Ioneer competitors and assessment
Company assessmentDirect peers
- Lithium Americas: U.S./Canadian lithium developer with flagship Thacker Pass project in Nevada, currently in construction. Directly comparable as a North American hard-rock lithium developer pursuing DOE financing and targeting similar EV/battery offtake customers.
- Piedmont Lithium: U.S.-listed lithium developer supplying spodumene concentrate and lithium hydroxide to OEMs including Tesla and LG. Comparable business model of binding offtakes with auto/battery customers and project financing tied to U.S. critical mineral policy.
- Albemarle Corporation: World's largest lithium producer and operator of the Silver Peak Mine in Nevada — currently the only producing U.S. lithium mine. Comparable as the only U.S. commercial lithium producer; also exposes Ioneer to the competitive supply landscape.
- Standard Lithium: Canadian-listed lithium developer pursuing direct lithium extraction (DLE) from Smackover brines in Arkansas and Texas. Comparable as a North American, pre-production lithium developer with offtake partnerships (e.g., with LANXESS, Equinor) targeting battery-grade lithium.
- Sigma Lithium: Hard-rock spodumene producer in Brazil shipping battery-grade lithium concentrate to customers including LG and Glencore. Comparable as a single-asset lithium developer/producer pursuing tier-1 battery offtakes and scaling toward battery-grade conversion.
- Livent Corporation: Vertically integrated lithium chemicals producer (carbonate, hydroxide) supplying major battery and industrial customers globally. Comparable as a battery-grade lithium hydroxide producer with a similar customer base to Ioneer's PPES and EcoPro offtake partners.
Broad incumbents
- SQM (Sociedad Química y Minera): One of the world's largest lithium and specialty chemicals producers with operations in Chile's Salar de Atacama. Comparable as a major, established global lithium hydroxide/carbonate producer selling into the same EV/battery value chain.
- Rio Tinto (Borates): Operates the Boron mine in California — one of only two global suppliers dominating the borates market alongside Eti Maden. Directly relevant as a competitor to Ioneer's boric acid production and a benchmark for borates cost curve positioning.
- Eti Maden (Turkey): State-owned Turkish miner and the world's largest producer of refined borates, accounting for roughly half of global supply. Comparable as the dominant incumbent in borates whose market share Ioneer's boric acid output will partially displace.
Others
- ioneer /ioneer USA Corp (Sibanye-Stillwater JV history): Sibanye-Stillwater previously held a 50/50 JV and $490M investment commitment in Rhyolite Ridge before exiting in February 2025. Relevant as a former strategic partner whose withdrawal illustrates the project's historical capital-raising risk profile.
