Investors cautious as Trigg Minerals issues unusual trading halt


Trigg Minerals (ASX:TMG) shares were halted on Thursday as the company paused share trading – but the reasons why were, if not unusual, definitely ambiguous.

Usually, trading halts are issued before the announcement of a capital raise, but they can also be proffered ahead of major operational updates.

However, none of those relate to Trigg’s Thursday disclosure.

“The trading halt is requested pending an announcement regarding an update of the Company’s ASX announcements dated 19 May 2025 and 20 May 2025,” the company wrote on Thursday morning.

If that sounds like the company’s been told off by ASX compliance, you’re not alone. Many investors in the relevant HotCopper discussion thread wondered aloud whether that’s what’s going on.

The issue here is that the stock’s been on a tear since 19-20 May, when the company made an announcement regarding hot-to-trot darling commodity antimony – namely, its acquisition of a “large-scale” project.

“Trigg has executed a purchase agreement to acquire 49 unpatented lode mining claims covering the strategic Antimony Canyon Project (ACP) in Utah, USA,” the company wrote back on May 19.

“[This jurisdiction is] the world’s top-ranked mining investment jurisdiction according to the latest Fraser Institute Survey,” Trigg added.

The company cited a U.S. Bureau of Mines report – from 1949 – citing a “foreign resource estimate of 12.7M metric tons grading 0.79% antimony for 100,300 tons of contained antimony.”

Big numbers, yes. But relying on an obscure report over 70 years old is what has some investors raising an eyebrow of concern over Trigg’s Thursday announcement regarding an update to its May 19 announcement.
