Barton Gold Reports High-Grade Assays from Infill and Extensional Drilling at Tolmer Deposit

Barton Gold (ASX: BGD) (OTCQB: BGDFF) has released a series of shallow, broad, high-grade assays from drilling at its Tolmer silver deposit in South Australia.

A recent 3,677-metre campaign targeted infills and extensions at the March 2025 discovery, after preliminary test work yielded a concentrate grading more than 100,000 grams per tonne (or 10%) silver.

The new intersections infill Tolmer’s 'western silver zone', and extend the footprint of shallow silver mineralisation to a total strike length in excess of 500m.

They also add broad high-grade intersections to depths of at least 200m at the eastern gold zone.

Numerous Silver Assays

Tolmer’s western zone is now host to numerous drilling assays exceeding 2,000 gram-metres silver, with key assays from this area also carrying material gold credits.

This zone hosts an ‘upper horizon’ of silver mineralisation largely independent of gold, and a second ‘lower horizon’ at the boundary of oxide and fresh zones that hosts both silver and gold in broad intervals.

Best assays from the latest program were 10m at 399g/t silver and 0.55g/t gold from 56m including 4m at 954g/t silver and 1.23g/t gold, and 16m at 120g/t silver from 5m and 16m at 493g/t silver and 0.66g/t gold from 50m including 5m at 282g/t silver, 3m at 1706g/t silver and 2m at 2.2g/t gold from 59m.

Preliminary analyses for petrology and structural interpretation are now underway, and Barton also hopes to expedite a full metallurgical analysis of Tolmer mineralisation by preparing composite samples from recent drilling.

Low Costs with High Margins

Managing director Alexander Scanlon said Tolmer continued to yield broad, high-grade silver assays across an expanding footprint.

“With a shallow profile and having produced trial concentrates grading over 100,000g/t silver, Tolmer is already hinting at real potential for a low-cost, high-margin operation,” he said.

“Our Tolmer and Tunkillia silver assets are emerging as possible significant contributors to our South Australian precious metals strategy, whether developed as a complement to our regional gold holdings or on a standalone basis.”

Barton is currently revising the 3.1 million ounce Tunkillia silver resource, where 58,000m of drilling was recently completed to support a resource upgrade, pre-feasibility study, mining lease application, and financing discussions.
