Special Report: Trigg Minerals is expanding its antimony portfolio with the acquisition of the previously producing Bukkulla mine and an extension to the Nundle Goldfield within the highly prospective New England Orogen in NSW.
Bukkulla previously produced antimony at grades exceeding 25% while a recent rock chip with a grade of 22.9% indicates there might be more of the silvery metal that has seen demand and prices soar in response to its increasing use in solar panels to increase their efficiency as well as Chinese export curbs.
Meanwhile, the tenement applications include the northern extension of the Nundle Goldfield, one of NSW’s most significant gold-producing regions in the 19th century.
No modern exploration has been conducted on these tenements, presenting a significant opportunity for discovery.
The acquisitions take Trigg Minerals’ (ASX:TMG) antimony footprint up to 1026km2, adding to its existing regional portfolio of 717km2 that includes the 29,902t Wild Cattle Creek antimony resource at its Achilles project as well as the Taylors Arm and Spartan projects.
“This is an exciting step forward for Trigg Minerals as we continue to diversify and grow our exploration footprint in highly prospective regions like the New England Orogen,” executive chairman Tim Morrison said.
“These new applications demonstrate our commitment to unlocking shareholder value by targeting highly prospective areas with strong potential for further major discoveries.”
Bukkulla (ELA 6870) covers 87km2 of highly prospective ground with known antimony mineral occurrences.
The historic workings extend 18m deep and 9m along strike, following an intrusive-related or a meta hydrothermal vein linked to the nearby Bundarra Plutonic Granitoid.
It also has a substantial dump with stibnite-bearing veins hosted in altered Texas Beds while recent sampling of massive stibnite and gangue returned assays of up to 22.9% antimony, 47g/t silver, 0.106g/t gold and 1300g/t arsenic.
ELA 6871, the North Nundle project, targets antimony and gold mineralisation within a structurally favourable setting adjacent to the Peel Fault and in the immediate extension to the historic Nundle Goldfield, one of the most significant goldfields in NSW during the 19th century.
The Nundle Goldfield sits within the New England Fold Belt, a region with a well-documented history of gold and base metal mineralisation focused along the Peel Fault.
Many historic goldfields in northeast NSW also host high-grade antimony deposits – such as Hillgrove and Trigg’s Wild Cattle Creek deposit, a fact that bodes well for North Nundle.
The acquisition package also includes the Tia project (ELA 6872), which encompasses multiple underexplored deep leads and reef gold occurrences, offering significant regional opportunities.
TMG plans to carry out systematic exploration, including geophysical surveys, sampling, and drilling programs, to test the depth extensions of the historically productive Bukkulla Mine and explore high-priority targets within the Nundle Goldfield.
