IRIS Metals Limited (ASX:IR1) Announces High-grade Drilling Results at Tin Mountain Project
Drilling Results
IRIS Metals reported significant high-grade lithium and caesium intersections from its Phase I diamond drilling program at the Tin Mountain Project in South Dakota, USA. Highlights include 5.2 meters at 2.05% Li₂O from 39.2 meters in hole TDD-24-008, and 1.0 meter at 1.54% Cs₂O from 31.2 meters in hole TDD-24-007.
Phase II Plans
The company confirmed that the pegmatite extends down-dip under cover and remains open at depth. Phase II drilling will target deeper zones using horizontal drilling technology and mineralogical mapping studies to progress towards a maiden mineral resource estimate.
Executive Comments
Matt Hartmann, IRIS Metals President of U.S. Operations, stated, “The Phase I drill results at Tin Mountain confirms high-grade mineralisation and the multi-element potential of the host pegmatite, including lithium and now caesium. Plans for Phase II are underway to target the central pegmatite zone which proved difficult to access with a conventional surface drilling approach. IRIS will leverage extensive surface exposure and historic mining operations, combined with 2025 advanced technologies, to deepen our understanding of the Tin Mountain Project and advance towards a maiden mineral resource.”
