ECR Minerals plc provided the fire assay gold results from the historic Duke of Cornwall Mine, Swifts Creek (Tambo), Victoria, Australia. As announced on 10 June 2024, ECR Minerals undertook an exploration campaign at its Eastern Victorian exploration tenement (EL007484) which included detailed mapping of historical gold workings and the collection of 56 rock chips and 84 soil samples at spaced intervals across and along strike of the known mineralisation. Initial testing of 37 rock chips using the Photon Assay method returned significant results with 8 samples showing gold concentrations exceeding 5 g/t Au, including a best result of 51.5 g/t Au.

The Board has now received the gold and multi-element results for all 56 rock chip samples, analysed using both traditional Fire Assay and ME-ICPMS methods. In comparing the 37 Photon Assays to the Fire Assays, all samples are within a 95% confidence level. The largest variance observed between assay methods was 2.05 g/t Au in rock chip BTR054.

It is acknowledged that gold results inherently exhibit some variance, as evidenced by duplicate and repeat testing for Au . A vein previously sampled in 2023, with a fire assay indicating 0.2 metres at 22 g/t Au, produced a photon analysis result consistent with expectations, measuring 24 g/t Au. All rock chip samples also underwent ME-ICP analysis to determine levels of Silver, Arsenic, Bismuth, Copper, Lead, and Zinc. Elements such as Arsenic (As) have traditionally been a key indicator for gold mineralisation.

Bismuth (Bi) has shown the closest correlation with gold at higher elevations and falls within the detectable range of a pXRF device, a valuable tool included in the Company's exploration toolkit. Pathfinder elements can be crucial for expediting and cost-effectively generating future regional exploration targets.
