Alba Mineral Resources plc said that analysis of drill core and in-mine rock samples has provided proof of four geochemical groupings at Clogau-St David’s gold mine in Wales.
AURIFEROUS VEIN
The assay analysis was of 2021 Phase II underground and surface drill core, 2019 drill core and additional in-mine rock samples.
A total of 23 elements were selected from which four distinct groupings were defined, believed to be auriferous veins, barren veins, sulphide-rich samples and host rock influenced.
Alba said that the most important grouping was the auriferous vein (AV) group.
This has a “compelling gold-silver-bismuth-lead-tellurium association indicative of the presence of gold-bearing mineralising fluids”.
It is also directly comparable to the basket of metals for the bonanza-grade gold stage described in historical ore mineralogy assessments for the Dolgellau gold field.
Additionally, the group is present in all key development target structures identified to date, “validating the potential of those targets to host untapped gold mineralisation”.
DEVELOPMENT
Alba’s executive chairman George Frangeskides added that two of the key targets defined for near-term development were the Llechfraith Payshoot and the Main Lode System Extension.
“The fact that we are seeing the same multi-element signature in these areas as was found in the bonanza-grade gold stage at Clogau, gives us a great deal of confidence as we move forward with the development of these zones.”
