Barton Gold Holdings (OTCQB:BGDFF) has announced promising soil assay results from its Tolmer and Black Oak Tank prospects at the Tarcoola Gold Project in South Australia. The company's March 2025 Tolmer discovery hole ranked as the 5th highest-grade silver intersection globally in H1 2025, yielding 6m @ 4,747 g/t Ag from 46m depth.

The new soil assays indicate potential northwest-southeast mineralization orientation and confirm broad surface gold, silver, and lead anomalism across Tolmer. May-June 2025 drilling confirmed high-grade silver extensions (~200-4,750 g/t Ag) within the 'western silver zone', alongside high-grade gold (~5-50 g/t Au). Results from 595.3m of oriented diamond drilling are pending, expected in early November 2025.

Barton Gold Holdings (OTCQB:BGDFF) ha annunciato promettenti risultati dei test del suolo dai suoi progetti Tolmer e Black Oak Tank presso il Tarcoola Gold Project nel South Australia. Il pozzo di scoperta Tolmer di marzo 2025 della società si è classificato come la 5ª intersezione di argento per grado a livello globale nel primo semestre 2025, fornendo 6 m a 4.747 g/t Ag da una profondità di 46 m.

I nuovi test del suolo indicano una potenziale orientazione di mineralizzazione da nord-ovest a sud-est e confermano una ampia anomalìa di oro, argento e piombo sulla superficie lungo Tolmer. Le trivellazioni di maggio-giugno 2025 hanno confermato estensioni di argento ad alto contenuto (~200-4.750 g/t Ag) all'interno della 'western silver zone', insieme a oro ad alto contenuto (~5-50 g/t Au). I risultati di 595,3 m di perforazione diamantina orientata sono attesi e dovrebbero essere comunicati all'inizio di novembre 2025.

Barton Gold Holdings (OTCQB:BGDFF) ha anunciado resultados prometedores de ensayos de suelo de sus proyectos Tolmer y Black Oak Tank en el Tarcoola Gold Project en Australia del Sur. El agujero de descubrimiento Tolmer de marzo de 2025 de la compañía figuró como la 5ª intersección de plata de mayor grado a nivel mundial en la 1.ª mitad de 2025, arrojando 6m a 4.747 g/t Ag desde 46 m de profundidad.

Los nuevos ensayos de suelo indican una posible orientación de mineralización de noroeste a sureste y confirman una amplia anomalía de oro, plata y plomo en la superficie a lo largo de Tolmer. Las perforaciones de mayo-junio de 2025 confirmaron extensiones de plata de alto grado (~200-4.750 g/t Ag) dentro de la 'western silver zone', junto con oro de alto grado (~5-50 g/t Au). Los resultados de 595,3 m de perforación diamante orientada están pendientes, esperándose a principios de noviembre de 2025.

Barton Gold Holdings (OTCQB:BGDFF)가 남호주 Tarcoola 금 프로젝트의 Tolmer 및 Black Oak Tank 탐사에서 토양 샘플 분석 결과를 발표했습니다. 회사의 2025년 3월 Tolmer 발견 구는 2025년 상반기 글로벌에서 5위로 높은 은 교차로 기록되었으며, 46m 깊이에서 6m당 4,747 g/t Ag를 산출했습니다.

새로운 토양 시험은 NW-SE 방향의 광물화 가능성을 시사하고 Tolmer 전역에 걸친 광범위한 표면 금, 은, 납 이상치를 확인합니다. 2025년 5-6월 시추는 'western silver zone' 내 고급 은 확장(~200-4,750 g/t Ag)과 함께 고급 금(~5-50 g/t Au)을 확인했습니다. 방향성 다이아몬드 시추 595.3m의 결과는 보류 중이며 2025년 11월 초 발표될 예정입니다.

Expansive surface Au-Ag-Pb anomalism suggests growth potential

HIGHLIGHTS

  • March 2025 Tolmer discovery hole ranked 5th highest-grade silver intersection reported globally during H1 2025, with an interval of 6m @ 4,747 g/t Ag from only 46m depth

  • May - June 2025 drilling confirmed extensions of high-grade silver (~200 - 4,750 g/t Ag) within 'western silver zone', with the emergence of high-grade gold alongside silver (~5 - 50 g/t Au)

  • New soil assays indicate potential northwest-southeast orientation of mineralisation and confirm broad surface gold (Au), silver (Ag) and lead (Pb) anomalism across Tolmer, with potential for material extensions of Au-Ag-Pb mineralisation in the 'western silver zone'

  • Assays for 595.3m oriented Tolmer diamond drilling pending (results expected early November), with results to help inform structural interpretation and follow up targeting across Tolmer

  • Other soil assays indicate potential gold anomalism consistent with interpreted structural features at Black Oak Tank prospect, along interpreted faults parallel to the Lake Labyrinth Shear Zone (LLSZ)

ADELAIDE, AU / ACCESS Newswire / September 23, 2025 / Barton Gold Holdings Limited (ASX:BGD)(OTCQB:BGDFF)(FRA:BGD3) (Barton or Company) is pleased to announce the assay results of ultrafine soil sampling programs completed at the Tolmer and Black Oak Tank prospects of its South Australian Tarcoola Gold Project (Tarcoola).

New assay results for these programs indicate potential for:

  • Tolmer: extensions of the high-grade 'western silver zone', and similar new previously untested targets located between the 'western silver zone' and the 'eastern gold zone'; and

  • Black Oak Tank: potential for interpreted structures to host continuous gold mineralisation.

Samples were collected during July 2025 over a ~1.9km2 surface area surrounding the Tolmer gold and silver discoveries, along with a ~23km2 area covering the LLSZ, both located on the Company's Tarcoola tenements.

Full details are contained in the complete announcement, which can be accessed on the ASX website, the investor section of Barton's website, or directly by clicking here.

Commenting on the Tolmer soil assay results, Barton Managing Director Alexander Scanlon said:

"These assays provide the first hints as to orientation at Tolmer, indicating a potential overall northwest-southeast trend to the western silver zone and the potential for material extensions of its high-grade silver-gold footprint.

"We have also identified potential new opportunities located between the 'western silver' and 'eastern gold' zones, where coincident Au-Ag-Pb anomalies present secondary targets analogous to the more prominent footprint of the 'western silver zone'. We expect that pending assays from our recent diamond drilling program in the 'eastern gold zone' will materially assist our interpretation of local structural controls, and guide follow up drilling targeting."
