Thor Energy PLC (AIM:THR, OTCQB:THORF, ASX:THR) said reconnaissance sampling at its projects in Colorado identified new anomalies and a first indication of high-grade copper.
That was at the Edna Mae prospect in the southern portion of the Wedding Bell mining claims, where rock chip sampling returned up to 5,424ppm (0.54 %) uranium, 1.6 % vanadium, 100g/t silver and 2.74 % copper.
Thor added this is the first high-grade copper value reported from the programme.
Edna Mae lies on the edge of the Paradox Copper Belt, which includes the Lisbon Valley Copper Mine in Utah.
Further work is needed to understand the copper distribution, and its relationship and distribution relative to the uranium-vanadium mineralisation, said the statement.
"The presence of high-grade copper with the uranium-vanadium assay results at the Edna Mae Prospect is very promising," commented Nicole Galloway Warland, Thor Energy's managing director.
"We are continuing our regional reconnaissance surface sampling program with exciting high-grade results and building additional drill targets to our priority Rim Rock and Groundhog prospects.
"2024 drilling preparations are in progress, with the intention of maiden drilling at Vanadium King Project, and we look forward to updating the market in due course."
