Taruga Minerals has its sights set on three large mafic intrusions on its project right next to where Chalice Mining and joint venture partner Venture Minerals are seeking the next big discovery of nickel-copper-platinum group elements. .
Taruga says he sees similarities in his rocks to the “intrusives” hosting the extraordinary discovery of Gonneville de Chalice which lies to the north in the same geological province.
Taruga’s Manjimup project is 240 km south of Perth in the Balingup metamorphic belt in the West Yilgarn nickel-copper-PGE province.
Chalice recently launched a drill rig at nearby Venture land to test a 20km-long magnetic anomaly that shows eerily similar electromagnetic signatures to its own massive Gonneville nickel/PGE discovery farther north in the same geological province.
Emboldened by nearby activity, Taruga embarked on its own field reconnaissance program focused on mapping and sampling the trio of potential intrusions at the eastern building of its Manjimup project.
The identified intrusive rocks rich in iron and magnesium, or “gabbros”, extend over 3 to 5 km long and 250 to 500 m wide. Importantly, Taruga notes that petrology work has confirmed the presence of disseminated chalcopyrite – a copper-bearing mineral – in rock chip samples from the gabbros.
Rock chip sampling also found abnormal levels of platinum group elements of up to 58 parts per billion.
Taruga believes its trio of intrusions hold promise for nickel-copper-PGE mineralization and also welcomes an independent report which it says indicates its gabbro intrusions are geologically related to the PGE-bearing Julimar complex containing the Gonneville deposit.
Taruga envisions that the next phase of reconnaissance exploration will include rock chip sampling, detailed mapping and additional fill geochemical sampling in selected areas. He indicates that high-resolution aeromagnetic surveys over selected areas will also be considered.
Ultramafics – rocks extremely rich in iron and magnesium – associated with gabbros have not yet been identified and, unsurprisingly, should not be seen in outcrops. The explorer says that the identification of ultramafic phases will be part of his ongoing work on the project.
Chalice’s groundbreaking discovery of a 330mt ore deposit in the same province drew explorers to West Yilgarn like a school of fish on a new burley spread. With lines pouring all over the region, it seems only a matter of time before another Gonneville appears in this rich but somewhat under-explored region.
