en.Wedoany.com Reported - Great Divide Mining (ASX: GDM) and Dart Mining (ASX: DTM) have obtained strong results of gold, silver, and antimony from drilling at the Coonambula joint venture project near Eidsvold in central Queensland.
Assay results for holes CBADD014 to CBADD022 completed by the end of February 2026 show: Hole CBADD019 intersected 5.8 meters at 1.73 g/t gold, 11.57 g/t silver, and 4.76% antimony from 53.7 meters depth, including 0.85 meters at 2.18 g/t gold, 71.12 g/t silver, and 26.66% antimony from 54.25 meters, and 1.3 meters at 3.43 g/t gold, 2.15 g/t silver, and 3.75% antimony from 56.02 meters; Hole CBADD018 intersected 6.1 meters at 1.11 g/t gold and 0.5% antimony from 33 meters depth, including 0.7 meters at 4.59 g/t gold from 35 meters, and 0.8 meters at 2.75 g/t gold and 3.74% antimony from 38.3 meters; Hole CBADD014 intersected 2.4 meters at 2.66 g/t gold, 6.44 g/t silver, and 0.76% antimony from 34.6 meters depth, including 0.9 meters at 4.34 g/t gold, 14.66 g/t silver, and 2.02% antimony from 35.4 meters.
Drilling results around the historic Banshee mine have revealed a silver- and antimony-rich core within a broader gold zone, which continues along the down-dip and strike directions of the orebody. This batch of holes tested over 500 meters of strike extension of the Banshee vein.
Under the joint venture agreement, Great Divide Mining is transferring a 51% interest in the Coonambula project to Dart Mining, which has committed to drilling aimed at delineating a JORC gold-antimony resource.
Dart Mining Chairman James Chirnside stated that drilling around the historic Banshee mining area highlights significant mineralization and grades, and these results have been used to deepen the understanding of mineralization controls. Chirnside added that the east-west extension of the mineralized zone shows these directions still have potential and remain open, with the team still intercepting veins, sulfide minerals, and strong alteration consistent with the main zone, and looks forward to results from west of the current drilling area. The team is cleaning diamond core and accelerating sample dispatch to obtain final assay results as soon as possible, in order to submit composite samples for metallurgical test work, support mineral resource estimation, and advance Dart's equity in the project to 51%.
Approximately 4,500 meters of diamond core have been completed at the Banshee target, with about 3,640.6 meters logged. Holes CBADD014, 018, and 019 completed most of the drilling of the Banshee "core," returning results defining silver- and antimony-rich intervals within a broader gold mineralized zone. The current western boundary of drilling is represented by CBADD017 and the eastern boundary by CBADD021, indicating the mineralized corridor persists, with logging showing the hydrothermal system remains active and well-developed at both ends of the drill footprint. CBADD017 returned only anomalous gold, suggesting it intersected the flank of the focused fluid channel rather than the core; CBADD021 is located on the flank or within a low-grade zone of the system, which remains open to the east.
GDM and DTM will continue to advance earn-in exploration at the Coonambula project and will announce results promptly upon receipt and approval of remaining diamond drilling assays. Subsequently, composite drill core will be selected for metallurgical testing to support ore type and recovery concepts. A three-dimensional model will also be established, and a JORC resource will be reported as soon as possible.
