Barton Gold Holdings Limited is advancing its exploration efforts at the Tolmer Silver prospect, situated in South Australia, with the commencement of a new drilling program. This initiative involves approximately 4,000 meters of reverse circulation (RC) drilling aimed at probing the extensions of the high-grade silver mineralization previously identified at the site.
The drilling program is designed to test new orientations and assess the continuity of the mineralized zones, based on an updated geological interpretation. This follows encouraging results from earlier drilling, where assays indicated significant silver grades, with some reaching up to 2,000 gram-metres of silver.
The Tolmer prospect is noted for its impressive silver concentrations, which were first identified in a 2025 discovery hole that yielded a remarkable peak intersection of 6 meters at 4,747 grams per tonne (g/t) silver, with additional gold grades. Multiple follow-up drilling campaigns have confirmed a continuous presence of silver-rich mineralization across various horizons.
Barton Gold’s Managing Director, Alexander Scanlon, emphasized the potential significance of the Tolmer Silver project within the company’s broader mineral exploration strategy. This drilling initiative will not only enhance the company’s silver portfolio but will also complement existing advancements at their Tunkillia gold project.
For this program, Barton Gold has selected Strike Drilling as the contractor responsible for executing the drilling operations. Their expertise is anticipated to facilitate efficient and effective assessment of the high-grade silver zones.
The ~4,000m reverse circulation program is designed to target extensions of high-grade silver mineralisation and to assess the continuity of the mineralisation based on a new geological interpretation. This focus on high-grade silver could yield attractive opportunities for future resource expansion.
Previous drilling assays have confirmed high-grade silver mineralisation, with some samples exceeding 2,000 gram-metres Ag and peak intersections revealing exceptionally high grades of 4,747 g/t Ag. Such strong results suggest promising potential for further discoveries.
Strike Drilling has been appointed for the drilling program, which is indicative of the company's commitment to ensuring that high-quality drilling operations are employed to advance their exploration efforts.
The drilling aims to infill the high-grade zone and investigate a potentially new interpretation of geological controls, providing valuable insights that may lead to more effective exploration strategies in the future.
The continued examination of the Tolmer Silver prospect is seen as a potentially significant contributor to Barton Gold's overall strategy, particularly as it pursues multiple avenues for enhancing its regional asset portfolio.
The recent preliminary yield of over 100,000 g/t Ag in high-grade concentrate indicates highly favourable conditions at Tolmer, which could enhance the economic viability of the prospect, aligning with investor interests.
The Tolmer Silver project complements Barton's existing resources, which include substantial gold and silver minerals, thereby potentially increasing the company's overall resource wealth and production capacity.
Barton holds significant JORC compliant mineral resources, including 2.2Moz of gold and 3.1Moz of silver. This robust resource base underscores the company's strong position in the resource sector and highlights potential for future growth.
