Aston Minerals Limited announced the delineation of a maiden Mineral Resource Estimate across the Edleston Main and Sirola Gold Prospects. The Mineral Resource represents the culmination of a substantial exploration program undertaken by Aston between February 2021 through to December 2022 aiming to infill and extend mineralisation at Edleston Main. In addition, exploratory drilling completed at the Sirola Prospect targeted the along strike extension of the Edleston Main trend which had only undergone limited exploration prior to Aston's involvement.

Sirola is considered to be a significant discovery based on its scale and the fact that it is open along strike to east and west. The Mineral Resource Estimation was undertaken by Cube Consulting, a Perth based independent geological and mining engineering consulting firm. The Edleston Project is located approximately 60km via road to the south of Timmins, Ontario, Canada.

The towns of Timmins and Kirkland Lake are located close by and host significant former and current producers, with required services and skilled labour available to support exploration and development of the Project. The region is globally recognised in terms of large scale open pit and underground operations. The scale of gold mineralisation delineated at Edleston, which represents only 20% of the strike tested to date, justifies a standalone team and focus to advance the Project.

The Company is cognisant of the capital and focus required to further advance the gold potential of the Project and on the basis of the outcome of the resource estimate is looking at opportunities to monetise the gold asset. This process may involve a trade sale, spin out into a new listing or farm in by an existing miner. The Company will keep the market informed of the process and provide updates as the process unfolds.

In excess of C$10M was spent on primarily geophysical and drilling activities across the Edleston Project by 55 North Mining Inc. (formerly SGX Resources Inc). Due to the lack of outcrop at surface, exploration was largely driven by a combination of detailed magnetics to define the structural and lithological framework. Induced Polarisation (IP) has been utilised effectively to directly target mineralisation.

Multiple moderate to strong IP chargeability anomalies paralleling and along strike from Edleston are yet to be drill tested. Predecessors completed a total of 156 diamond drill holes for >46,000m of drilling. The drilling was predominantly on 50m section spacing with holes 50m apart on section and 10 to 100m vertical spacing down dip.

Drill core facility and associated drill core diamond drill holes are available on site. Exploration across Edleston Main, Central Zone and Sirola consisted predominantly of drilling with 60 diamond drill holes for 28,360m completed utilised in the Resource Estimate. The Edleston Main and Sirola Gold Mineral Resource has been estimated to have an Indicated Resource of 14.0 million tonnes at 0.9 g/t Au for 400,200 oz Au and Inferred Resource of 34.1 million tonnes at 1.0 g/t Au for 1,099,800 oz Au at 0.4 g/t Au cut off grade.

The Indicated and Inferred Resource totals 48.1 million tonnes at 1.0 g/t Au for 1,500,100 oz Au at a cut off grade of 0.4 g/t Au. The Mineral Resource has been reported in accordance with the 2012 Edition of the JORC Code. Cube considers that the data collection techniques are consistent with good industry practice and are suitable for use in the preparation of a MRE to be reported in accordance with the JORC Code.

Available quality assurance and quality control (QAQC) data supports the use of the input data provided by Aston. The MRE is considered to have a reasonable prospect for eventual economic extraction (RPEEE) on the following basis: Location of the Project in a favourable mining jurisdiction with an extensive history of large scale open pit and underground mining operations; Proximity to infrastructure including low cost, environmentally responsible hydroelectric power; No known impediments to land access or tenure; and The width, geometry and grade of the MRE is amenable to mining extraction via traditional open pit mining methods. Open pit optimisation is currently underway and further updates will be provided once completed.
