Sun Silver Ltd (ASX:SS1) has told investors it’s looking into the widespread presence of antimony in its flagship Maverick Springs project in Nevada, and considering how this in-demand mineral could become a new focal point for the company, given recent developments in international trade.

Although chiefly a gold and silver project – with an inferred JORC resource of 423 million ounces (Moz) silver equivalent (AgEq) at 67.25 grams per tonne (g/t) of AgEq – Maverick Springs also has a vast array of antimony, with assays yielding up to 13,199 parts per million (ppm) – or 1.32%.

And recent announcements of trade restrictions on the U.S. from China – in response to Trump’s tariff rollout – have made the need to access this mineral locally much more important, especially given 90% of the U.S. supply comes from overseas sources, mainly China, Russia and Tajikistan.

Consequently, Sun Silver is now in the process of re-logging, pXRF testing, and re-assaying historical core from the project to identify how much antimony it contains – and to integrate it into future mineral resource updates.

Managing director Andrew Dornan said finding antimony at Maverick Springs represents a strategic opportunity for the company.

“With the US being heavily reliant on foreign antimony supply and against the backdrop of recent export restrictions from China, our project is emerging as a potential domestic source for this critical mineral,” Sun Silver’s boss explained.

“Given the widespread distribution of the mineralisation and consistent orebody characteristics, we are optimistic about the potential to define additional antimony – and to unlock the value of that antimony alongside our large silver-gold resource.

“In parallel with advancing the silver-gold development, we are actively engaging with U.S. government agencies and industry stakeholders to position Maverick Springs as a key contributor to the establishment of secure, domestic supply chains for critical minerals.”
