Barton Gold grows high-grade silver zone at Tolmer with expanded RC drilling program
Barton Gold (ASX: BGD) (OTCQB: BGDFF) has completed an expanded drilling campaign at the Tolmer high-grade silver discovery within its Tarcoola gold project in South Australia.
Geological surface reconnaissance and early drilling observations saw Barton expand the campaign in all directions with two additional lines to the north and south.
The company reallocated seven holes it had originally planned for the eastern ‘gold zone’ to eight new holes in the western ‘silver zone’, expanding its planned drilling from three to five lines.
RC drilling program
Barton completed total of 2,882 metres of reverse circulation (RC) work across 21 holes to an average depth of 137m.
The original campaign comprised only 13 holes for 2,500m and the company designed it to infill and extend Tolmer’s western ‘silver zone’ and the eastern ‘gold zone’.
Barton aimed to gather a larger amount of data on this area while keeping to the same drilling schedule.
Latest assays
Managing director Alexander Scanlon said Barton would now send samples to the lab for expedited assaying this week, expecting first results by end July.
“We look forward to sharing the latest assays for this round of Tolmer drilling,” he said.
“The western ‘silver zone’ is an exciting target and we are already planning near-term follow-up work to build on the safe execution of this extended program.”
High-grade silver zone
Barton identified Tolmer as a high-grade gold discovery in August and, by early-2025, had confirmed a new high-grade ‘silver zone’ approximately 500m west in a line of seven discovery holes.
The follow-up program comprised 17 RC holes for a total 2,230m of drilling and returned globally significant assays such as 6m at 4,747 grams per tonne silver from 46m including 1m at 17,600g/t, 4m at 1,417g/t silver from 9m including 1m at 3,790g/t and 14m at 434g/t silver from 46m including 1m at 3,350g/t.
Barton’s exploration team has already commenced planning for follow-up programs, including diamond drilling for structural orientation and further extensional RC drilling.
