The latest announcement is out from ioneer Limited ( (AU:INR) ).

Ioneer reported further optimisation of its Rhyolite Ridge project during the December 2025 quarter, delivering a 19% increase in unlevered life-of-mine NPV to US$2.24 billion, an 8% uplift in IRR to 18%, and higher forecast annual output of both lithium hydroxide and boric acid, underpinned by improved leach processes and more efficient reagent use that lower operating costs. The company’s updated mine plan now spans 77 years entirely from reserve material and incorporates higher throughput via reduced leach times, while ongoing engagement with the U.S. government and strategic partners is bolstered by boron’s addition to the U.S. critical minerals list, reinforcing Rhyolite Ridge’s strategic importance to domestic supply chains and providing optionality for future expansion, including potential development of a Stage 2 plant for low-boron ore.

The most recent analyst rating on (AU:INR) stock is a Hold with a A$0.23 price target. To see the full list of analyst forecasts on ioneer Limited stock, see the AU:INR Stock Forecast page.
