The company, which has a stake in the mine through its 49% interest in the project’s owner, Gold Mines of Wales (GMOW), said detailed underground surveying by means of three-dimensional (3D) scanning of immediately accessible areas within the upper adit has been completed.
A 3D geological model is being constructed for the entire licence area and the existing mine workings.
Alba said a preliminary mine plan is being generated and the primary targets for regional gold exploration are being refined for the spring 2018 field programme.
“The underground scanning of the extensive mine workings, and the 3D geological model that we are developing, will be invaluable assets in leading us to the principal targets for unworked gold mineralisation within the mine,” said George Frangeskides, the executive chairman of Alba.
“Having identified over 300 known gold occurrences within the wider project area, we are certainly spoilt for choice," he added.
"This is a known and vastly under-explored gold belt - the great majority of it under licence to GMOW - and we are excited by the prospect of exploring the highest priority gold occurrences in the coming weeks,” Frangeskides said.
Shares in Alba were up 1.1% at 0.359p following the announcement.
