Highlights
The initial PlatsolTM process testing on the Dana and Lismer Zones rougher flotation concentrate samples returned positive results with the best observed test results showing final extractions of 93% palladium, 88% platinum, 98% gold, 99% copper and 98% nickel for Dana and 93% palladium, 85% platinum, 98% gold, 100% copper and 98% nickel for Lismer;
PGM precipitation recovery testing showed 99% palladium, 94% platinum and 99% gold were recovered in a low-weight final precipitate with grades of 2,908 g/t Pd, 882 g/t Pt and 56.6 g/t Au for Dana and 99% palladium, 77% platinum and 99% gold recovered in a low-weight final precipitate with grades of 1,832 g/t Pd, 607 g/t Pt and 8.32 g/t Au for Lismer. These high precipitation recoveries are in-line with the Platsol process;
Sample material for the Platsol testing was derived from 2021 drill core of the Dana and Lismer Zones stored at SGS
The sample materials at SGS were composited using the same procedures and recipes as used to make the rougher Cu-PGM sulphide concentrates for the 2023 PEA and Additional, follow-up testwork recommended.
These two zones were subject to the proof-of-concept PLATSOL testwork reported herein. Also shown are pit-constrained Mineral Resources at

Platsol Testwork Results for
Two mineralized samples from the Dana and Lismer Zones were subjected to a proof-of-concept PlatsolTM process amenability testwork program for the recovery of palladium, platinum, gold, copper and nickel. Rougher flotation on the Dana and Lismer samples provided adequate amounts of concentrates for the purpose of this initial PlatsolTM process testing.
