Oacoma, South Dakota

Mn-REE +/- Ni, Co, Cu Project

Technology Minerals has acquired a 15% working interest in the Oacoma Project, South Dakota, USA and an option to acquire up to a further 85% working interest on the terms of an exploration agreement that are to be agreed with North American Strategic Minerals Inc. who own mineral leases over 3,083 acres in South Dakota, United States. This property is considered prospective for manganese and rare earth elements, as well as nickel, cobalt, copper.

The Oacoma project is a multi commodity exploration project dominated by manganiferous units with elevated rare earth elements and base metals. The area is quite barren due to the elevated manganese content (20 – 25% Mn) in the soils.

In February of this calendar year, Technology Minerals announced the results from 27 rock samples collected in October 2021 at the Stratabound Manganese-Rare Earth Oxides Project. The samples comprised of mudstone and gypsum-phosphate concretions from within the Sharon Springs Formation, and manganiferous concretions from within the DeGrey Formation.

Two samples out of the 27 submitted samples reported total rare earthoxide ("REO") values of 0.22% and 0.34%, with associated neodymium(Nd) oxide + praseodymium (Pr)oxide ("NdPr") values respectively of 0.034% and 0.037% NdPr.

Seven of the 27 samples reported manganese oxide ("MnO")grades greater than 20% MnO, with the highest grading at 29.1% MnO.

Current status: Further exploration campaign with a more comprehensive and extensive sampling and mapping programme.

The project is considered to be prospective for manganese, cobalt, nickel, copper, precious metals and rare earth metal. Two field visits have taken place and assays from the last visit are pending.
