Miramar Resources Limited has identified several promising IOCG targets at its Whaleshark Project in Western Australia using advanced modelling techniques. This discovery bolsters the company's potential in copper, gold, and related mineral exploration, setting the stage for exciting future drilling initiatives for investors.
Miramar Resources Limited has announced a significant development at its Whaleshark Project in Western Australia, where new modelling techniques have revealed several targets potentially hosting Iron Oxide Copper-Gold (IOCG) mineralisation. The project, fully controlled by the company, is situated about 40 kilometres east of Onslow in the Ashburton region. The recent re-modelling of historic geophysical data using the Magnetisation Vector Inversion (MVI) technique has highlighted overlapping gravity and magnetic anomalies, a key signature for large IOCG deposits. Previous exploration, including aircore drilling in 2022 and EIS co-funded diamond drilling in 2023, showed promising geochemical anomalism and the presence of chalcopyrite, lending further credence to the potential for significant copper and gold mineralisation beneath shallow cover.
The innovative use of MVI modelling addresses limitations of traditional 3D susceptibility techniques by accounting for magnetic remanence. This advancement has allowed the company to conduct detailed structural analyses at Whaleshark, mapping collapse features, hydrothermal migration zones, and deep fluid pathways that delineate prospect areas. The technical illustrations provided by the company include cross-sectional views of targets T8, T9, T11, and T12, where overlapping magnetic (pink) and gravity (blue) inversion models clearly mark possible drilling targets. This emphasis on cutting-edge geophysical methods is seen as a strategic move that could improve the accuracy of drill-hole placements and reduce exploration risk.
In tandem with the Whaleshark update, Miramar is progressing on other fronts. Ongoing drilling at its Gidji JV Gold Project north of Kalgoorlie moves into its final stages, with assay results expected in the coming weeks. Meanwhile, exploration at the Bangemall Ni-Cu-PGE Project in the Gascoyne region has provided encouraging geological insights, including the identification of mafic cumulate rocks and sulphide mineralisation over an extended strike length. A detailed magnetic and electromagnetic survey at Bangemall is set to commence in early July under co-funding arrangements with the WA Government.
Investor sentiment regarding Miramar Resources Limited is mixed. On the bullish side, the use of advanced modelling techniques at Whaleshark may pave the way for breakthrough discoveries in a region with shallow prospective basement rocks, which is relatively rare compared to other IOCG provinces. The successful integration of geophysical data and the robust progress on multiple projects indicate a proactive approach and a strong commitment to exploration. However, on the bearish side, the company remains in the exploration phase with limited drilling intersections to date, which means that further drilling and assay results will be critical to validate the potential identified by the new targets. As such, while the technical advancements and dual project progress point to potential upside, the inherent risks associated with early-stage exploration continue to limit certainty in near-term returns.
