ABOUT BUBALUS RESOURCES

Bubalus has six projects, the Victorian Gold Projects, the Yinnietharra Lithium Project (prospective for lithium), Amadeus Project (prospective for Manganese), the Coomarie Project (prospective for Heavy Rare Earths), the Nolans East Project (prospective for Light Rare Earths) and the Pargee Project (prospective for Heavy Rare Earths), which are located in the Northern Territory and Western Australia:

Victorian Gold Projects (Au/Sb) – A portfolio of 8 granted licences in the heart of the Victorian Goldfields. Headlined by the Crosbie Project, which has drill ready targets supported by high grade surface gold and antimony, geophysical anomalies, and geological characteristics.

- Nolans East Project (Light REEs) The project covers 380 km² of the Arunta Province, analogous to Nolan’s Bore light rare earth deposit and is prospective for light rare earths, located only 15 kms east of Arafura’s (ASX:ARU) 56Mt NPV $1.011Bn light rare earth deposit.

Yinnietharra Project (Li) - Yinnietharra Project with the boundary of E09/2724 lying only 2 km east of the Malinda Prospect owned by Delta Lithium Limited (ASX:DLI) ( Delta ). Drilling at Malinda by Delta has identified spodumene-hosted lithium mineralisation over a distance of 1.6 km and to a depth of 350 m[1] .

Amadeus Project (Mn) - Significant land package with 150 kms of strike containing outcropping high-grade manganese covering 5,436 km², located 125 km south of Alice Springs, where historical exploration has identified 11 manganese occurrences, along with cobalt, gallium and Ni-Zn-Cu also identified.

Coomarie Project (Heavy REEs) - The project covers 1,315 km² and presents as a geological analogue to Browns Dome, host to Northern Mineral’s (ASX:NTU) Browns Range heavy rare earths deposit where mineralisation is hosted on margins of granite dome intrusive where the unconformity between Gardiner Sandstone and Browns Range Metamorphics exist and located in the Tanami Region.

Pargee Project (Heavy REEs) - The project is prospective for heavy rare earths and located 30 kms from PWV Resource’s (ASX:PVW) Watts Rise heavy rare earths discovery.
