Portfolio Map

Ontario pegmatite portfolio map.

An updated regional map distinguishing held claims from monetized properties is in preparation. In the interim, the property-status table above is the authoritative reference for the current standing of each holding.

Map update in preparation
A revised Ontario portfolio map is being prepared to clearly distinguish properties held by Usha from those monetized via the Panther, Totec, and Molten transactions. Until then, please refer to the property-status table above.
Deposit Model

LCT-type pegmatites.

The Ontario portfolio sits within highly evolved lithium-cesium-tantalum pegmatite systems in the Thunder Bay Mining Division.

Geochemical signature.

Sampling across the portfolio has identified the geochemical fingerprint typical of evolved LCT pegmatites: low K/Rb ratios (often <30), low Nb/Ta ratios, spessartine-rich garnets, and blue-green apatite.

Surface assay maxima reported across the broader Ontario portfolio (including divested properties) include up to 0.5% Li2O (~2,310 ppm Li), 1,833 ppm Cs, and 4,100 ppm Rb. Surface grab samples are selective by nature and not necessarily representative of mineralization on the properties.

Disciplined portfolio optimization.

Three core pegmatite properties have been monetized: Rubidium Ridge (Panther), White Willow (Totec), and Gathering / Triangle Lake (Molten). Usha retains meaningful equity in each acquirer plus a 2.0% NSR over Rubidium Ridge — preserving long-term upside without ongoing operating spend.

Non-core claims (Nym Lake, Bingo East, Bingo West) remain held in the belt as the company focuses operating capital on Southern Arm and Jackpot Lake.

Cautionary statement on sampling. Surface grab and historical channel samples are selective by nature and not necessarily representative of mineralization on any property. Where adjacent-property data is referenced for geological context, mineralization on adjacent or nearby properties is not necessarily indicative of mineralization on Usha's properties.
