Abstract
L'invention concerne un procédé sans explosion permettant d'extraire un minerai d'un gisement filonien de minerai (12), la veine étant extraite par éclatement en fragments du minerai contenu entre les parois rocheuses (16) bordant la veine (12). Les fragments de minerai sont récupérés, par exemple, par aspiration, puis ils sont ultérieurement traités de manière à récupérer le minéral précieux.
