The East Laverton Nickel Project comprises four granted exploration licences covering an area of 405km2, located approximately 35km from the town of Laverton. The Diorite Hill layered magmatic intrusion (Diorite Hill) is a prominent geological feature in the region covering an area of 110km2 and comprising ~7,000m of cumulate mafic and ultramafic intrusive rocks. It is considered prospective for intrusive style nickel-copper-PGE mineralisation. In addition, the Company’s tenure incorporates ~14km of interpreted ultramafic stratigraphy within the Granite Well and Rotorua trends. These trends are considered prospective for Kambalda style komatiitic nickel mineralisation. East Laverton is also prospective for orogenic gold, with intercepts such as 9m @ 2.4 g/t Au, including 5m @ 4.2 g/t from 48m reported from historic drilling (hole EIC001, WAMEX A48007).
Great Southern Mining Limited announced in March 2026 that co-funded EIS diamond drilling had commenced at the Diorite Hill Layered Intrusive Complex. This drilling will target stratigraphic horizons considered prospective for reef-style PGE-nickel-copper mineralisation with a single 900m deep hole.
The diamond drill rig is then planned to relocate to the Company’s Duketon Gold Project to drill at least two holes into the Golden Boulder target area. The first hole will be an EIS co-funded hole up to 700m deep at the Ogilvies prospect. This will be the first diamond and first deep drilling in the Golden Boulder area, where previous RC drilling has rarely penetrated below 150m from surface.
The co-funded drilling grants were independently assessed through a competitive application process with only 39 successful applications. The EIS is noted for awarding grant funding to high quality projects with technical merit and provides funding to enable the testing of exploration concepts and the use of new exploration technologies.
