About The South Dakota Project

The Black Hills of South Dakota are famous for historic lithium mining dating back to 1898 when Li-bearing spodumene and amblygonite was first mined near the township of Custer. IRIS controls 2,105 federal mineral claims and has agreements over two patented claim blocks.

Existing project areas include:

• Beecher Project – including Longview and Black Diamond

• Tin Mountain Project

• Edison Project

• Ingersoll Project

• Helen Beryl Project

• Tinton Project

The Beecher pegmatite trend was mined sporadically between the 1920’s and 1950’s for lithium, beryllium, tantalum, mica and feldspar. Limited amounts of lithium spodumene ore from the Beecher mines was shipped to Hill City during the 1940’s where it was processed through a flotation circuit.

IRIS’ is currently moving the Beecher Project to near-term development and has been granted mining licenses permitting lithium pegmatite mining for these patented claims.

These mining licenses, granted by the State of South Dakota, enable IRIS to fast-track all exploration and mining activities including the right to explore and mine lithium bearing pegmatites.
