Siren Gold (ASX:SNG) has become the latest explorer to dip its toe into the antimony thematic with that company boosting its Auld Creek prospect mineral resource for the critical mineral to 14,500 tonnes (14.5Kt).

Worth noting – New Zealand, home to Auld Creek, has just drafted a new critical minerals list.

Included is antimony, following a recent Chinese decision to curb exports of that metal. China is no longer the world’s largest producer, per the USGS.

The overall global MRE for gold equivalent (AuEq) in Siren’s portfolio – that’s Auld Creek and all of its other assets – now sits at over 1.4Moz AuEq.

The equivalent metric is often used to capture gold, alongside other metals, like silver – in this case, antimony.

At the upgraded Auld Creek resource, gold increased by 58% to 38Koz. The updated MRE comprised the Fraternal and Bonanza East shoot targets of interest including a drill run from earlier in 2024.

“The updated Reefton MRE of 588koz AuEq, positions the project to be further drilled and developed, with only a small drilling program having been carried out in 2024,” Siren CEO Victor Rajasooriar said.

“The Auld Creek project has only been drilled to approximately 150m below surface and the potential to grow that further is outstanding given the mineralisation trend continues at depth.

“The antimony resource having increased by nearly 66% positions Reefton to be a potential supplier of antimony to western countries and could fast track New Zealand as the next producer of this critical mineral.”

SNG last traded at 6.7cps.
