Three ASX companies with United States critical metals ambitions released updates. Diablo Resources (ASX:DBO), Perpetual Resources (ASX:PEC) and Metallium (ASX:MTM) each published an update that is covered below.

Diablo Resources (ASX:DBO): Assays

Tungsten up to 0.37% WO3 and 0.17% WO3 with 2.82 g/t gold, plus channels of 2.6m at 1.56% Cu and 3.0m at 1.00% Cu.

Two wartime adits give underground access and sampling is under way.

Perpetual Resources (ASX:PEC): Results

Underground samples ran 12.03%, 5.79%, 5.76%, 4.89%, 4.48%, 3.28%, 2.60% and 1.34% WO3. Garnet-pyroxene skarn at the granite-limestone contact gave 1.18% and 1.10%, in line with historical grades, and Viking's Daughter chips 1.03% and 0.40%.

Some samples carried copper and silver, such as 0.38% Cu and 12.49 g/t Ag, and an ore pile at a copper-gold prospect 210m northeast of the shaft returned 55.9 g/t gold, 386 g/t silver and 1.43% copper, near Denton-Rawhide.

Metallium (ASX:MTM): Scope

The parties will review feedstock, tolling, offtake, hedging, prepayments and Working Capital facilities, and strategic investment, across metals such as magnetic rare earths, gallium, germanium, tungsten, copper, nickel and PGMs.

Definitive agreements are targeted for selected opportunities by 31 December 2026. Either side may terminate on 30 days' notice, and Flash Metals USA cannot talk to others on similar collaborations until 31 December 2026.

Why These Updates Could Matter

Diablo Resources: Surface and channel samples guide where 2027 drilling goes. Perpetual Resources: These are selective samples from old workings, so they guide drill planning rather than define a resource. Metallium: The MOU frames negotiation and timing rather than committing either side.

Closing Thoughts

Diablo Resources (ASX:DBO), Perpetual Resources (ASX:PEC) and Metallium (ASX:MTM) each issued US critical metals updates, summarised above using the figures in their filings.
