The company’s business centers on developing a large-scale deposit that can produce lithium compounds and boron products from a single ore body. ## Products & services • Lithium from the Rhyolite Ridge project • Boron products from the same deposit • Project development and mine construction • Mineral processing and beneficiation planning • Long-term supply agreements for battery customers - **Lithium development** (55%) — Development of lithium-bearing ore into battery-grade lithium products. - **Boron development** (35%) — Production of boron-related outputs from the same mineral resource. - **Project development services** (10%) — Mine planning, permitting, engineering, and construction readiness work. - Lithium from the Rhyolite Ridge project - Boron products from the same deposit - Project development and mine construction - Mineral processing and beneficiation planning - Long-term supply agreements for battery customers ## Customers ioneer’s customer base is anchored by industrial and mobility customers that need long-term supply of lithium and boron. The company has announced offtake relationships with battery and EV-related counterparties, reflecting demand for feedstocks used in batteries and specialty materials. Boron also serves customers in glass, construction, electronics, and defense applications. - **Battery and EV supply chain** (primary) — Buys lithium output for use in batteries and related upstream materials. - **Industrial boron users** (primary) — Buys boric acid and boron products for glass, ceramics, and insulation. - **Specialty materials customers** (secondary) — Buys boron-based inputs for electronics and performance applications. - **Defense-related users** (secondary) — Buys boron products used in ferroboron and boron carbide applications. - Battery and EV manufacturers seeking lithium feedstock - Cathode and materials groups needing lithium supply - Industrial buyers of boric acid and boron compounds - Glass, ceramics, and insulation end markets - Defense and electronics customers using boron materials ## Geography The company is headquartered in Australia but its principal project is in Nevada, United States, where Rhyolite Ridge is being developed. Its commercial exposure is therefore concentrated in the U.S. project footprint while its customer reach is international through battery and industrial offtake relationships. Nevada is strategically important because permitting, infrastructure, and local operating conditions all affect project execution. - **United States** (100%) — Principal development project and operating exposure are in Nevada. - Head office in Australia - Principal project in Nevada, United States - U.S. permitting and regulatory oversight are central to execution - Customer and offtake exposure extends to Asia and North America - Nevada location links the business to the U.S. battery supply chain ## Strategy The core strategy is to advance Rhyolite Ridge into production as a long-life source of lithium and boron. Securing permits, financing, and offtake agreements is central because the project must connect a single mineral resource to two demand pools: battery materials and industrial boron. The company also emphasizes stable supply, which supports long-term customer relationships and project bankability. - **Complete project financing and strategic partnering** (short-term) — Large-capital mining projects require funding and partners before construction can proceed. - **Move from permitting to construction** (short-term) — Construction readiness converts a development asset into a future operating mine. - **Convert resource strength into long-term supply contracts** (medium-term) — Offtake agreements help secure demand visibility and improve project economics. - **Develop dual-product revenue exposure** (medium-term) — Lithium and boron diversification reduces dependence on a single market. - Advance Rhyolite Ridge toward construction and production - Monetize both lithium and boron from one ore body - Use offtake agreements to support project financeability - Secure permits and maintain environmental compliance - Position as a U.S.-based supply source for critical minerals ## Risks ioneer’s principal risks are development-stage execution risk, commodity price exposure, and permitting/environmental compliance around a large Nevada mining project. Because the business is still moving toward construction, delays in financing, approvals, or engineering can materially affect timing and capital needs, while lithium and boron prices influence the eventual economics of the project. - **Project development and construction risk** [high] — The company depends on a single large project moving through financing and build phases. - **Permitting and environmental compliance** [high] — Mining projects require ongoing state and federal approvals and monitoring. - **Commodity price volatility** [high] — Lithium and boron selling prices will drive the project’s future revenue and margins. - **Single-asset concentration** [high] — The business is focused on one development asset, limiting diversification. - Mine development delays can push out cash generation - Permitting and environmental approvals are execution-critical - Lithium and boron price swings affect project economics - Large capital projects face financing and cost overrun risk - Single-project concentration increases operational exposure ## Accounting As a development-stage miner, the most important accounting judgments relate to capitalization of project costs, impairment testing, and asset valuation ahead of commercial production. Because the company presents in USD and holds plant and equipment that are depreciated over short useful lives, future capitalized development balances and any impairment indicators will be important to watch as the project advances. - **Capitalized project development costs** — Changes reported asset base and future expense recognition - **Impairment assessment** — Could lead to write-downs if project assumptions weaken - **Property, plant and equipment depreciation** — Affects operating expense after project commissioning - **Environmental and reclamation estimates** — Influences liabilities and earnings estimates - Capitalization of project development costs affects asset values and future expense timing - Impairment testing is critical for a pre-production mining asset - Plant and equipment depreciation will rise as construction assets are placed in service - USD reporting affects presentation of Australian-incorporated operations - Environmental provisions and compliance obligations may require estimates --- *Last updated: 2026-09-28T12:18:52.276063+00:00*
