Ioneer Quadruples Ore Reserve at Rhyolite Ridge Project

ioneer Limited Sponsored ADR ( (IONR) ) has issued an update.

On June 2, 2025, Ioneer Limited announced a significant upgrade to the Ore Reserve estimate for its Rhyolite Ridge Project, increasing it from 60 million tonnes in 2020 to 247 million tonnes. This expansion supports a 95-year mine life and positions the project as the largest lithium-boron reserve globally. The updated project economics highlight a robust financial outlook with an after-tax NPV of $1.367 billion and an IRR of 14.5%. The project’s low-cost production strategy, prioritizing high-boron ore, ensures profitability even at low lithium prices, with boric acid contributing significantly to revenue. This development reinforces Ioneer’s competitive positioning in the global lithium market, offering flexibility and economic advantages unmatched by other lithium projects.

Spark’s Take on IONR Stock

According to Spark, TipRanks’ AI Analyst, IONR is a Underperform.

The primary concern for IONR is its poor financial performance, with no revenue generation and continuous net losses, which heavily weigh down the overall score. Technical analysis suggests bearish sentiment, while the valuation reflects financial instability. The absence of earnings guidance or strong corporate events further limits upside potential.
