IRIS building a clear U.S. critical minerals platform across #lithium, #rubidium and #tungsten. Beecher remains a key asset as the story continues to evolve....

As the market increasingly prioritises projects that can move beyond #exploration, @IrisMetals has been featured among ASX juniors progressing toward maiden #resource definition.

IRIS Metals has defined what we believe is the only rubidium component within a US mineral resource estimate 🔛3.03Mt at 1.00% Li₂O and 0.116% Rb₂O at Beecher, South Dakota. High-grade zone: 1.04Mt at 0.203% Rb₂O — ~2,100t in-situ Rb₂O.

Lithium + rubidium, same system. IRIS is building a unique U.S. critical minerals story at Beecher. 🎧 Hear Matt Hartmann explain it

@IrisMetals has delivered an updated JORC 2012 #MRE at Beecher of 3.03Mt @ 1.00% Li₂O and 0.116% Rb₂O (Indicated & Inferred), highlighting a rare lithium–#rubidium combination in the Black Hills, South Dakota. Positioned in a tier-one U.S. jurisdiction with an existing mining licence, Beecher is emerging as a compelling multi-commodity #criticalminerals project aligned with domestic supply priorities. Importantly, this is believed to be the only U.S. mineral #resource estimate incorporating rubidium, reinforcing Beecher’s strategic relevance at a time of increasing focus on secure, domestic critical minerals supply Full release - wcsecure.weblink.com.au/pdf/…

Most people have never heard of #rubidium. It may be the most strategically important #metal you've never considered. $IR1 #Rubidium #CriticalMinerals @IrisMetals

Rubidium is rapidly emerging as a high-value strategic critical mineral, with prices reportedly reaching approximately US$1 million per tonne. A recent @StockheadAU article highlights growing US Government support for domestic and allied supply chains, creating strong tailwinds for ASX-listed developers. @IrisMetals stands out with some of the highest-grade rubidium intercepts recorded in the United States at its fully permitted Beecher Lithium-Rubidium Project in South Dakota. The updated Beecher Mineral Resource Estimate for lithium with a high-grade rubidium component is on track for end of this month, positioning IRIS as a potential near-term contributor to secure US critical minerals supply. As Washington prioritises domestic supply security, IRIS is ideally placed to benefit from this strategic shift. Read more⤵️ tinyurl.com/yf8xa5yh #CriticalMinerals #Rubidium #ASX #Mining
