摘要
A free-blast method for extracting ore from an ore vein deposit (12) wherein the vein is extracted by causing the ore comprised between the rock walls (16) bordering the vein (12) to spall into fragments. The ore fragments are recuperated as by aspiration and subsequently processed to retrieve the precious mineral.
