Duke Exploration Ltd (ASX:DEX) has intersected copper mineralisation for the first time within the central Bundarra Intrusive Complex (BIC) at its flagship Bundarra project in Queensland.
The company completed a shallow reverse circulation (RC) scout drilling program targeting untested structures and anomalous magnetic features interpreted by Leigh Rankin, a well-regarded industry expert.
The confirmation and accuracy of the geophysical structural interpretation for the first-time copper mineralisation within the central BIC is very promising for the future exploration potential of the BIC.
Looking ahead, identifying controlling structures provides a road map for future-focused exploration seeking the copper fluid pathways, sources and areas of accumulated mineralisation.
“Significant step”
Commenting on the completed geophysical and structural target drilling program, Duke managing director Philip Condon said: “The confirmation of the geophysical interpreted structures being mineralised is a significant step forward in understanding the BIC and how to focus future exploration efforts.
“It is the first-time copper mineralisation has been intersected in the centre of the BIC, which is under transported soils cover.
“This validates the use of the geophysical exploration technique and provides prospective targets acting as fluid pathways and feeder structures.
“All required samples are at ALS laboratories with an anticipated six-week turnaround on assays after which we can finalise a comprehensive Bundarra summary report for market release.”
Drill program
The Bundarra scout drilling program targeting untested structures and anomalous magnetic features interpreted by Rankin in 2022 at Valkyrie has now concluded
A selection of priority samples has been sent to ALS laboratories for analysis and full results will be reported when received over the two next months.
The presence of mineralisation within the geophysical interpreted structures is the first-time copper mineralisation has been intersected within the central BIC, further increasing the prospectivity of the area.
