Barton Gold Soil Sampling Program Confirms Extensions to Tarcoola Mineralisation
Assays from ultrafine soil sampling programs completed at Barton Gold’s (ASX: BGD) Tarcoola project in South Australia have indicated the presence of extensions to the mineralisation and new drilling targets.
The company reported expansive surface gold-silver-lead anomalism at the Tolmer and Black Oak Tank prospects with potential for material extensions of mineralisation in the western silver zone beyond the current drilling footprint.
Barton collected the samples in July over a 1.9 square kilometre surface area surrounding the Tolmer discovery and a 23 sq km area covering the Lake Labyrinth Shear Zone, with the results identifying new and untested coincident gold-silver-lead profiles that may represent other attractive targets.
High-Grade Mineralisation
The most recent aircore and reverse circulation drilling at Tolmer identified silver-dominant and high-grade gold-silver mineralisation, while Black Oak Tank returned low-level gold values that appear continuous and coincident with interpreted basement-hosted structural features.
Barton had expedited soil sampling and diamond drilling at Tolmer through July and August, collecting 443 samples at 100 metre x 100m spacings, with selected infill to 50 x 50m spacings, along with a total of 416 samples from Black Oak at 100m spacings along 500m spaced lines.
Historical regional-scale calcrete sampling in the area returned a maximum 17 parts per billion gold, with a maximum result from Barton’s program of 26.2ppb gold.
“The multiple zones of continuous gold between adjacent lines is encouraging, however further analysis is required before we can confirm the results,” managing director Alexander Scanlon said.
Potential for Extensions
Mr Scanlon said the company was happy with its continued progress of Tarcoola exploration.
“These assays provide the first hints as to orientation at Tolmer, indicating a potential overall northwest-to-southeast trend at the western silver zone, and the potential for material extensions of its high-grade silver-gold footprint,” he said.
“We have identified potential opportunities between the western silver and eastern gold zones, where coincident anomalies present secondary targets analogous to the more prominent footprint of the western zone.”
Barton anticipates assays from diamond drilling at the eastern zone will materially assist its interpretation of local structural controls and guide follow-up drill targeting.
