Barton Gold identifies third potential revenue source at Tolmer

New high-grade silver and gold zones confirmed

Follow-up drilling underway to expand mineralisation

Barton Gold (ASX:BGD) (OTCQB:BGDFF) has announced a significant step forward at its Tolmer prospect in South Australia, with the discovery of new high-grade gold and silver zones that may evolve into a third revenue-generating asset alongside its Tarcoola and Tunkillia projects.

Recent assays from Tolmer have expanded mineralisation west of the Tarcoola site, revealing a shallow and broadening silver-rich zone and a separate gold-bearing area located approximately one kilometre to the east. These results build on an earlier drilling campaign from November, which uncovered one of Australia's highest-grade near-surface silver results—an impressive 17,600 grams per tonne—within a broader halo of anomalous lead.

The standout silver assays from the latest round include 4 metres at 1,417g/t from a depth of just 9 metres, with a peak intercept of 1 metre at 3,790g/t. Another notable result featured 23 metres at 95g/t silver from 4 metres. On the gold side, assays returned 5 metres at 4.38g/t from 49 metres, including a 1-metre section at 13.6g/t, highlighting strong mineralisation potential.

The Tolmer drilling also uncovered instances of high-grade gold occurring within the top silver intervals, specifically at the transitional boundary between oxidised and fresh rock. Barton Gold is currently investigating whether this gold could be integrated into existing operational plans, particularly as high-grade blending feed for Stage 1 and 2 processing at Tarcoola. Such integration could enhance project economics and reduce overall production costs.

A new drilling and geochemical program is now in progress, aiming to map potential extensions of the silver zone in western, northern, and southern directions.

Strategically located just 5 kilometres west of Barton’s historic Perseverance mine and 130 kilometres from its fully-permitted Central Gawler Mill, Tolmer benefits from logistical proximity to existing infrastructure. The prospect’s position also supports potential synergies with the Tunkillia project, 70 kilometres away, enhancing future processing flexibility.

If further exploration confirms a broad high-grade transitional blanket, Tolmer may be developed as a standalone silver oxide deposit through low-cost open-pit mining and direct-shipping to industrial customers.

This latest development strengthens Barton Gold’s (BGD) portfolio and underscores the increasing value of its Central Gawler region assets, positioning the company to tap into broader commercial opportunities across multiple fronts.
