Mar 13, 2023 (Therese Pettigrew) - Edleston is located within the Abitibi Greenstone Belt of Archean metavolcanic and metasedimentary assemblages which have been steeply folded with the axes trending in a general east-west direction. These have been intruded mainly by large granitic bodies and by masses of mafic and ultramafic rocks and well as several ages of younger dolerite dykes. Regionally the Project is located within the western extension of the Cadillac-Larder Fault Zone (Aston Minerals ASX release Feb 21, 2023).

Mar 13, 2023 (Therese Pettigrew) - The Boomerang Resource is interpreted to be a dunite/peridotite unit which has undergone extensive serpentinization. This process of is responsible for the reaction of olivine to produce magnetite and brucite, resulting in a strongly reducing environment whereby nickel is released from decomposition of olivine. The nickel which has been released is typically partitioned into low sulphur nickel sulphide minerals. DDH DDED21-065 returned 0.24%Ni and 0.01% Co over 144.5 m including 0.45% Ni and 0.013% Co over 10 m. DDH DDED22-078 returned 0.28% Ni and 0.01% Co over 321.15 m (Aston Minerals ASX release Feb 21, 2023).
