Highlights

TEM has received excellent results from the first metallurgical sample at Remorse.

Davis Tube Recovery (DTR) test results show up to 68.8% Fe concentrate at a 25µm grind size.

The results highlight low impurity levels and high recoveries.

Results from the remaining composite samples are expected in the coming weeks.

Tempest Minerals Ltd (ASX:TEM) has received encouraging initial metallurgical results from the Remorse Iron discovery in Western Australia.

Composite sample #1, taken from drillhole WARDH00160, returned Davis Tube Recovery (DTR) results showing an iron concentrate grade of up to 68.8% Fe at a grind size of 25µm. This sample included 9 x 1m mineralised magnetite intervals between 93m and 102m downhole. Key highlights include:

Average calculated head assay grade: 32.29% Fe
Low impurity levels, including:

Silicon dioxide (SiO₂): 3.82%
Alumina (Al₂O₃): 0.12%
Manganese (Mn): 0.036%
Phosphorus (P): 0.031%

These preliminary results are considered ‘very encouraging’ and will be followed up with additional metallurgical and petrological testing to further optimise the concentrate quality, according to the company update. Further results from the remaining composite samples are expected in the coming weeks.

Tempest has made several key announcements for the Remorse Deposit, including the release of an exploration target, an inaugural Inferred Resource estimate, and the signing of an MoU with GreenSteel and Iron Pty Ltd to explore potential processing synergies. Metallurgical testing has commenced on over 5 tonnes of drill material, with early results from Composite 01 showing promising potential, supporting further test work to optimise concentrate quality.

The next steps include the integration of data into the deposit assessment and the planning of further project development activities.

Remorse is part of TEM’s flagship Yalgoo Project in Western Australia. It totals more than 1,000 km²and is located near high-profile neighbours across multiple commodities, including base metals (ASX:29M) and (ASX:TGN), gold (ASX:SPR), (ASX:VAU) and (ASX:CMM), and iron (ASX:FEX), Karara Mining Ltd and Sinosteel Midwest Group.
