IRIS Metals Uncovers Exceptional 3.30% Li₂O at Edison Project

IRIS Metals (ASX: IR1) has reported one of the highest-grade lithium intercepts in the Black Hills region with their latest diamond drilling program at the Edison Project in South Dakota, revealing an exceptional 3.30% Li₂O concentration.

The Phase I diamond drilling program, consisting of 15 holes totaling 2,278 meters, has successfully confirmed high-grade lithium mineralisation across multiple pegmatite dikes, significantly expanding the project’s resource potential.

Standout Results Confirm High-Grade Potential

The latest assay results from IRIS Metals Edison Project Results include exceptional intercepts that showcase the project’s impressive lithium concentration:

• • 6.65m @ 3.30% Li₂O from 54.6m (EDD-25-009)
  • 2.95m @ 2.76% Li₂O from 95.3m (EDD-25-007)

These new results build on previously reported high-grade findings:

• • 13.4m @ 1.78% Li₂O from 41.5m, including:
    • • 7.0m @ 2.22% Li₂O from 43.5m
      • 2.4m @ 2.51% Li₂O from 52.5m (EDD-25-001)
  • 3.6m @ 1.21% Li₂O from 33.4m, including:
    • • 1.9m @ 1.84% Li₂O from 35.1m (EDD-25-004)

“We are very pleased with the exceptional results from the Edison Project’s diamond drilling campaign, confirming high-grade lithium in the pegmatite dike system and providing some of the highest-grade lithium intercepts to date in the Black Hills,” commented Matt Hartmann, IRIS Metals U.S. Operations President.
