Corazon Mining Ltd (ASX:CZN) has started on-ground exploration at the Miriam Nickel Sulphide Project in the Eastern Goldfields region of Western Australia after being granted prospecting licences.
Fieldwork will initially focus on the project’s nickel potential via a high-powered ground electromagnetic (EM) geophysical survey.
This will test the Miriam Nickel Sulphide Deposit and interpreted extensions with the EM method suited to detecting bedrock conductors such as massive sulphides.
The equipment is configured to minimise the effect of conductive cover and improve the interpretability of any bedrock conductors detected.
About Miriam
Miriam, which is about 10 kilometres south-southwest of Coolgardie and is prospective for nickel, lithium and gold, consists of five prospecting licences, three of which were granted on January 23, 2023, allowing the company to begin its planned exploration activities.
The nickel sulphide deposit was discovered in 1969 with the discovery hole returning 9.6 metres at 5.60% nickel and has a long history of ownership by gold-focused companies, with relatively little modern nickel exploration.
Miriam is on a trend of ultramafics best defined by the undeveloped Miriam deposit and the Nepean nickel mine of Auroch Minerals Ltd (ASX:AOU).
Modern methods
Corazon said that modern, high-powered geophysics provided the opportunity to better test and map historically defined high-grade nickel sulphide mineralisation.
A 'moving loop' survey will cover the prospective trend of around 2.4 kilometres, on 200-metre spaced lines with 100-metre spaced stations. The latest technology SQUID sensor will be used for optimal sensitivity.
Lithium potential
Miriam is also prospective for lithium with Corazon having recently discovered lithium (spodumene) bearing pegmatite. Geochemical sampling is planned to test for lithium-bearing pegmatites in parallel with the company’s nickel focus.
Surface geochemical sampling is planned to be undertaken as a priority, testing for indications of lithium-bearing pegmatites under shallow soil cover, within the project area.
