Miramar Resources Ltd (ASX:M2R) has identified the potential for nickel sulphide mineralisation within the 80%-owned Gidji joint venture (JV) Project in the Eastern Goldfields of Western Australia, where the company has been exploring for gold and other minerals since October 2020.
Miramar conducted a review of new and historic data over the project with a focus on nickel sulphide potential.
The company identified a cluster of highly anomalous nickel and copper results where the magnetic signature was strongest within the project’s Ultramafic Highway, indicating Miramar may have found the thickest part of the mineralised sequence.
The Gidji Project’s Ultramafic Highway is adjacent to the Scotia Basalt, which forms the footwall sequence to the nickel sulphide mineralisation at Auroch Minerals Ltd (ASX:AOU)’s Saints nickel deposit further to the north.
Dual exposure to gold and nickel
Miramar Resources executive chair Allan Kelly said the company was excited about the potential for nickel sulphide mineralisation at Gidji alongside the many gold targets currently being explored.
“It’s well known that gold and nickel mineralisation occur in close proximity at many places within the Eastern Goldfields region,” Kelly said.
“Although the Highway Ultramafic hosts nickel sulphide deposits in at least two locations along the Boorara Shear/Bardoc Tectonic Zone, there has been minimal targeted nickel exploration at Gidji.
“The new nickel sulphide targets we have identified again confirm how underexplored the Gidji Project is, not just for gold, but for other commodities as well.”
Forward plan
Much like the rest of the mining industry, Miramar is awaiting a substantial number of assay results, including multi-element data, from the December 2021 aircore drilling programme and from recent reverse circulation (RC) drilling.
There was a lack of multi-element data over most of the project until its recent drilling, with the 4-kilometre-long magnetic anomaly beneath Gidji Lake remaining poorly tested.
Miramar will test for nickel sulphide mineralisation as part of an upcoming Boorara North aircore program, while assay results will inform an EM survey over one or more of the nickel sulphide targets once they are returned.
At the Bangemall nickel-copper-platinum group elements (PGE) projects, Miramar is still waiting for EM survey data from the Mt Vernon Prospect but is already planning to undertake a series of soil and rock chip sampling programs over the main EM anomalies once the data has been received and modelled.
About Miramar Resources
Miramar Resources is a mineral exploration company with highly prospective exploration projects in the Eastern Goldfields, Murchison, and Gascoyne regions of WA.
The company, which listed on the ASX in October 2020 following a heavily oversubscribed $8 million IPO, has three underexplored gold projects near Kalgoorlie – Gidji JV, Glandore and Randalls.
Miramar also has two projects in the Murchison in under-explored greenstone belts – Lang Well and Lakeside – and two in the Gascoyne region – Whaleshark and Bangemall – all prospective for either nickel-copper-platinum group elements and/or gold.
Miramar’s board has a track record of successful discovery, development and production within Australia, Africa, and North America.
