Barton Gold (ASX:BGD) expanded its second-phase upgrade drilling at the Tunkillia project in South Australia, following interim analysis of reverse circulation drilling assays published to date, according to a Tuesday filing with the Australian bourse.
The analysis identified potential to extend total mineralization at the project, upgrade mineral resources within the May 2025 optimized scoping study pit outlines, and increase the grade profile and classification of starter pit mineralization, the filing said.
Other work programs remain on schedule for target completion of a pre-feasibility study before the end of the year, per the filing.
Shares fell 2% in midday trade on Tuesday.
