It’s going to be massive to semi-massive: Cosmos launches AEM over chunky anomalies at Byro East

Cosmos Exploration (ASX:C1X) is literally off the ground at Byro East, with the WA-based gold, copper and nickel explorer making its maiden Airborne Electromagnetic survey (AEM) at its 100% owned Ni-Cu-PGE Project.
In exciting news for the RareX (ASX:REE) spinoff, C1X says the milestone means the greenfields focused team is entering the final phase of target generation work ticking every box – from soil sampling, AMAG/AMRAD and Gravity Surveys – all completed this year, before breaking ground on the highly-prospective project.
C1X Executive Chairman Jeremy Robinson told Stockhead of the anticipation within the Cosmos team, which share little doubt of the top notch potential of the Byro East prospect.
“This is an exciting time for Cosmos and the Byro East Project.
“If we are successful in delineating AEM targets coincident with the other anomalies then we will undoubtedly have some first-class Ni-Cu-PGE sulphide drill targets to test in an underexplored terrain, we should know very soon,” Robinson says.
The planned 1941 line kilometre AEM survey will cover well over 600 square kilometres of gneissic- mafic-ultramafic terrane perspective for Ni-Cu-PGE magmatic sulphide-related mineralisation.
For geologically-minded digging enthusiasts, this is exactly the kind of formations which have made household names of projects like Julimar and Nova-Bollinger.
Getting the Ni-Cu-PGE-related sulphide ducks in order
The AEM survey will target massive to semi-massive Ni-Cu-PGE-related sulphides over priority areas identified from the recently acquired Ground Gravity, Regional Surface Geochemistry and Airborne Magnetic datasets. Utilising the UTS (Geotech) VTEM Max system, Cosmos will prioritise gravity-high and magnetic anomalies coincident with Ni-Cr-Cu mafic lithogeochemistry for the survey.
Robinson says the gravity high features likely indicate close proximity to more significant accumulations of mafic-ultramafic host lithologies, increasing the prospectivity for these areas.
Assay results from a geochemical survey executed in April and may, have been encouraging, the company says, highlighting “significant, widespread coincident Ni-Cr-Cu lithogeochemistry across the central tenement package.”
These findings indicate mafic host rocks are far more prominent within the Byro East gneissic terrane than previously interpreted – increasing the potential for the project to host magmatic sulphide deposits.
Byro East
Byro East was pegged by $45m market cap rare earths explorer RareX last year, before spinning out Cosmos for a listing on the local exchange in December 2021.
The site has been the subject of intense speculation. As green as they come – Byro East has never been drilled in anger yet – but Robonson’s team has already identified four key areas which are the most prospective for Ni-Cu-PGEs.
Aside from Byro East for the hugely valuable nickel-copper-PGEs, Cosmos has another project – in New South Wales, ‘Orange East’ where the digger is focused on gold and copper.
Based on past exploration work, Cosmos has also identified several gold-copper targets at the smaller 40sqkm project.
