Dive deep into the lithium frontier with Matt Hartmann, President of US Operations at IRIS Metals Limited, as he unveils the company's ambitious strategy in South Dakota's mineral-rich Black Hills.
Matt reveals how this ASX-listed company has quietly amassed an impressive 170-square-kilometer portfolio of mining claims since pivoting to US lithium in 2022. What makes their approach particularly compelling is the speed at which they're advancing—already boasting 20,000 meters of drilling, multiple permitted pegmatites, and the recent completion of test mining at their flagship Longview deposit.
The conversation explores their initial resource of 2.2 million tons at just over 1% Li2O at Longview, but perhaps most fascinating is the detailed look at Tin Mountain – a unique pegmatite containing spodumene crystals "the size of tree trunks" alongside a treasure trove of other critical minerals including cesium, tantalum, and beryllium.
At the heart of IRIS Metals' strategy is their hub-and-spoke model, designed to maximize efficiency by operating multiple high-grade mine sites simultaneously to feed a centralized processing facility. Matt explains how this approach capitalizes on the outcropping nature of the pegmatites and the region's excellent infrastructure, enabling a development that harmonizes with local communities.
