Drilling Extends Ni-Co Sulphide Mineralisation Along 250m strike at Bardwell

Key Highlights

• Multiple significant intercepts at Bardwell Prospect have extended the drill tested strike to 250m, intercepts include:
  o DDED21-059intersected 183m at 0.38% Ni and 0.012% Co ending in mineralisation, starting from 84m including 76.2m at 0.46% Ni and 0.013% Co
  o DDED21-060intersected 293m at 0.32% Ni and 0.012% Co ending in mineralisation, starting from 52m including 51m at 0.45% Ni and 0.016% Co
  o DDED21-061intersected 165.1m at 0.33% Ni and 0.013% Co ending in mineralisation, starting from 220m including 50m at 0.4% Ni and 0.016% Co
• Results presently pending for 5 holes at Bardwell, extensive nickel sulphides logged
• Maiden drill hole into Elbow Prospect, 2.7km East-North-East of Bardwell, DDED22-078 intersected 321.2m at 0.28% Ni and 0.01% Co ending in mineralisation starting from 41.8m

Aston Minerals Limited (ASX: ASO, 'Aston Minerals' or 'the Company') is pleased to provide an update on drilling results and exploration underway across the Bardwell and Elbow Prospects within the Boomerang Nickel-Cobalt Target, Edleston Project, Canada.

Managing Director, Dale Ginn, commented "We have confirmed 250m of strike so far at Bardwell from a total of ~1,000m of prospective strike and have hit substantial nickel sulphides on each section. The incredible thickness and consistency of mineralisation gives us a strong degree of confidence in the substantial potential endowment of this Prospect.

To further extend the understanding of the distribution of mineralisation within the Boomerang Target, we decided to drill a hole at the Elbow Prospect. This is located 2.7km east-north-east of Bardwell. DDED22-078 reported 321.2m at 0.28% Ni and 0.01% Co from the shallow downhole depth of 41.8m. As we progress through infill between areas of defined mineralisation, on an extremely broad spacing, we are yet to find a zone within this 6.5km long intrusion that is not mineralised to a significant degree.

We look forward to providing further regular updates on the progress underway across Bardwell and other prospects within the Boomerang Target."

Bardwell Drilling

A total of 10 holes covering 250m of strike have been completed across Bardwell. Core processing and analytical results are presently pending for 5 of these holes.

The final batch of results for DDED21-059 was returned which resulted in the mineralised intercept increasing to 83m at 0.38% Ni and 0.012% Co ending in mineralisation. In addition, significant results were reported for DDED21-060 and DDED21-061:

• DDED21-060intersected 293m at 0.32% Ni and 0.012% Co ending in mineralisation, starting from 52m including 51m at 0.45% Ni and 0.016% Co
• DDED21-061intersected 165.1m at 0.33% Ni and 0.013% Co ending in mineralisation, starting from 220m including 50m at 0.4% Ni and 0.016% Co

Detailed geological logging of DDED22-080,DDED22-082 and DD22-084 has defined extensive nickel sulphide mineralisation.
