Golden Globe Validates Copper-Gold System with Phase 1 Drilling at Dooloo Creek

Phase 1 Drilling Validates Exploration Model at Dooloo Creek

Golden Globe Resources (ASX:GGR) has delivered a robust vote of confidence in its geological model at the Dooloo Creek Project in Queensland, confirming copper-gold mineralisation through its recently completed Phase 1 diamond drilling program. The program successfully intersected mineralised magnetite skarn and a large hydrothermal breccia system at the Northern Gold and Eastern Breccia prospects respectively, underpinning a district-scale intrusion-related copper-gold system.

At Northern Gold, drill hole NG001 returned a standout interval of 7.38 metres grading 0.55% copper and 0.46 grams per tonne gold, including a high-grade 1-metre section at 2.74% copper and 2.6 g/t gold. The mineralisation is hosted within a magnetite skarn system structurally controlled by the Dooloo Diggings Fault, a key regional feature. This intersection also showed elevated bismuth levels, suggesting a complex sulphide assemblage that could be an important vector for exploration.

Eastern Breccia Reveals Extensive Hydrothermal System

Further afield, the Eastern Breccia prospect yielded broad mineralised intervals, including 45.55 metres at 0.07% copper and 0.43 g/t gold, with higher-grade zones such as 6 metres at 0.28% copper and 2.18 g/t gold. The drilling confirmed a large intrusive breccia system with pervasive hydrothermal alteration and sulphide mineralisation extending nearly 500 metres downhole. The geochemical signature; marked by arsenic, silver, bismuth, cobalt, and zinc; supports the interpretation of a volatile-rich intrusive source at depth.

The preservation of volcanic host rocks alongside intrusive breccia architecture suggests the hole may have intersected an upper vertical section of the mineralising system. This setting draws parallels with notable Queensland deposits like Mount Leyshon and Kidston, where mineralisation intensifies toward deeper intrusive bodies.

Integrated Geophysical and Geochemical Data Reduces Exploration Risk

The Phase 1 results have validated the company’s multi-disciplinary targeting approach, which integrates magnetic inversion modelling, induced polarisation surveys, surface geochemistry, and structural interpretation. This strong correlation between geophysical anomalies and mineralisation significantly de-risks ongoing exploration and boosts confidence in untested targets across the project area.

Following these encouraging outcomes, Golden Globe has initiated Phase 2 diamond drilling, focusing on deeper extensions beneath the Eastern Breccia mineralisation and further high-grade zones at Northern Gold. The second phase aims to test the prediction of increasing mineralisation intensity closer to the intrusive sources, a critical step in assessing the project’s scale and commercial potential.

Financial Position and Tenement Portfolio

Golden Globe Resources ended the June quarter with a cash balance of approximately $3.5 million, after expending $1.7 million on exploration activities including drilling and geophysical surveys. The company’s expenditure remains broadly in line with its prospectus use of funds, having spent just over half the allocated budget on exploration across its Queensland and New South Wales projects.

The company holds 100% ownership of three granted tenements in Queensland covering nearly 267.97 square kilometres, including the Dooloo Creek project area. It also maintains a joint venture agreement to earn up to 90% interest in a New South Wales tenement. Some regulatory relinquishments have reduced the portfolio area, reflecting standard exploration licence conditions.
