Great Southern Mining is an Australian mineral exploration company focusing on gold and nickel projects in Western Australia and Queensland.

Great Southern Mining
Great Southern Mining is a mineral exploration company focused on the discovery and development of gold and base metal deposits in Western Australia and Queensland. The company holds significant landholdings in well-established mining districts, including the Laverton Goldfields in Western Australia and the Mt Carlton region in northern Queensland. Key activities involve geological mapping, geochemical sampling, airborne geophysics, and reverse circulation drilling programs targeting high-grade gold, nickel-copper-PGE sulfides, and porphyry copper-gold systems. The business aims to advance early to advanced-stage mineral targets toward potential development and resource expansion near regional processing facilities.
Snapshot
Products and/or services of Great Southern Mining
- Gold Exploration: Conducts extensive reverse circulation drilling and detailed geological mapping across mineral tenements in the Laverton greenstone belt, targeting shallow high-grade gold mineralization located near existing third-party processing facilities in Western Australia.
- Advanced Gold Development: Manages shallow open-pit gold deposits with established JORC-compliant mineral resource estimates, focusing on metallurgical test work, mine planning, and environmental baseline studies to support potential commercial toll-treatment options in Western Australia.
- Nickel-Copper Sulfide Exploration: Executes ground magnetic surveys, soil geochemistry, and electromagnetic targeting across ultramafic intrusive complexes to discover magmatic nickel, copper, and platinum group element sulfide mineralization within prospective Western Australian greenstone belts.
- Porphyry Copper-Gold Exploration: Surveys extensive hydrothermal alteration systems in northern Queensland using induced polarization geophysics and structural mapping to guide deep diamond drilling programs targeting high-tonnage, intrusive-related copper-gold mineralization.
- Epithermal Silver and Gold Targeting: Undertakes surface rock chip sampling, trenching, and high-resolution geophysical surveys across prospective mineral tenement acreage to define shallow epithermal gold and silver drill targets adjacent to established regional mining operations.
- Regional Target Generation: Evaluates regional airborne geophysical datasets, structural geology models, historical drilling databases, and remote sensing imagery to generate, prioritize, and tenure-secure new greenfield and brownfield mineral exploration targets across Australia.
