Golden Globe Resources has launched Phase 2 diamond drilling at its Dooloo Creek project, focusing on deeper copper-gold mineralisation following encouraging Phase 1 results at Eastern Breccia and Northern Gold.
- Phase 2 drilling targets deeper breccia and skarn mineralisation
- EB001 returned assays up to 0.52% Cu and 6.5g/t Au
- Northern Gold’s NG001 hole showed up to 2.74% Cu and 2.6g/t Au
- Geochemical and magnetic data support mineralisation potential at depth
- Drilling aims to test interpreted intrusive breccia system and magnetic anomalies
Phase 2 Drilling Targets Deeper Mineralisation at Eastern Breccia
Golden Globe Resources Ltd (ASX:GGR) has kicked off its Phase 2 diamond drilling program at the Dooloo Creek Project in Queensland, aiming to build on the promising copper and gold intersections from its initial campaign. The current hole EB002 is drilling deeper beneath the multi-stage breccia intersected in EB001, which returned assays including 0.52% copper and 6.5 grams per tonne gold over narrow intervals.
EB001 revealed a broad breccia system with 6 metres grading 0.28% Cu and 2.18g/t Au between 125 and 131 metres, including a higher-grade 0.61 metre section with 0.47% Cu and 6.5g/t Au. The company’s geological model interprets this as part of a large-scale intrusive breccia system, with geochemistry suggesting mineralisation could intensify at depth. EB002 is designed to test this hypothesis by drilling below the anomalous zones identified in EB001.
Northern Gold Drilling to Probe Magnetic Anomaly and Skarn Mineralisation
At the Northern Gold prospect, follow-up drilling is planned to target the core of a magnetic anomaly and the steeply dipping skarn zone first intersected in hole NG001. That hole returned significant results, including 7.38 metres at 0.55% Cu and 0.46g/t Au, with a standout 1 metre section grading 2.74% Cu and 2.6g/t Au.
The planned hole aims to reach deeper into the interpreted intrusive or intrusive breccia on the western side of the Dooloo Diggings fault, guided by magnetic inversion modelling and surface geochemical anomalies involving gold, bismuth, molybdenum, and tungsten. This approach seeks to clarify the extent and continuity of the skarn mineralisation and its relationship to the broader breccia system.
Geological Model Supported by Geochemistry and Magnetic Data
Golden Globe’s managing director Colin McMillan highlighted the importance of this drilling phase, noting that demonstrating the scale of the multiphase mineralisation model is a key objective. The breccia and skarn zones show a clear link between surface geochemistry, magnetic data, and target modelling, reinforcing the potential for a substantial mineralised system.
The EB001 hole also featured strong sericite-carbonate alteration, sulphide mineralisation, and pathfinder elements such as arsenic, silver, bismuth, cobalt, and zinc. These signatures are consistent with mineralisation sourced from volatile intrusive activity at depth, with widespread chlorite alteration interpreted as a halo around the intrusive source.
Next Steps and Market Implications
With Phase 2 drilling underway, investors will be watching closely for assay results that could confirm the depth extension of the mineralised systems at Dooloo Creek. The program’s success could significantly enhance the project’s resource potential and underpin further development decisions.
This drilling campaign follows Golden Globe’s earlier Phase 1 results that validated the geological model and copper-gold mineralisation at Dooloo Creek, setting the stage for this deeper exploration push. The company’s strategic focus on testing magnetic anomalies and geochemical targets aligns with industry best practice for discovering high-grade intrusive-related mineral deposits.
Bottom Line?
Phase 2 drilling at Dooloo Creek aims to unlock deeper copper-gold mineralisation, with assays awaited to confirm the scale and grade of the system.
Questions in the middle?
- Will Phase 2 assays confirm increased mineralisation at depth in the breccia system?
- How extensive is the intrusive breccia and skarn mineralisation beyond current drill intersections?
- What impact could these drilling results have on resource estimates and project valuation?
