Aston Minerals Limited reported results from the early-stage metallurgical testing of nickel-cobalt sulphide mineralisation from the Boomerang Nickel-Cobalt Target, Edleston Project, Canada. The first phase of metallurgical testing commenced in late first quarter of 2022 and represents the first beneficiation testing conducted on nickel-cobalt sulphide mineralisation from Bardwell. The testwork has demonstrated that the sulphide mineralogy is amenable to conventional flotation techniques.

The flotation testing completed to date has only utilised open circuit testing and is only at the early stages in terms of optimisation of the liberation and floating parameters. A 30kg sample of mineralisation from DDED21-076 was submitted for analysis with the head grade of the analysed sample approximating the overall nickel-cobalt abundance of the entire mineralised interval. The mineralised interval for DDED21-076 is a total of 163.5m at 0.51% Ni and 0.016% Co.

Forward Plan: Resource Definition Drilling: Continue resource definition drilling at Bardwell which has currently tested a mineralised strike of ~1.5 km and remains open along strike and at depth. Metallurgical Testing: Testing of lower grade domains of mineralisation from Bardwell underway. Geomet model being developed based on increased metallurgical characteristics of mineralisation.

Locked cycle testing to be conducted on both DDED21-076 and subsequent mineralisation. Exploration Target: Quantification of the mineralisation potential of Bardwell is being developed in detail with an exploration target range being evaluated.
