We visited Sandfire Resources NL's DeGrussa mine - 900km north of Perth, Western Australia -ahead of Diggers & Dealers 2012 as part of a group of about 76 people on a 100-seater Cobham aircraft that flew to the new airstrip in about 1.5 hours.DeGrussa is a classic VMS ore-body due to the presence of chimneys (like Nautilus Minerals Inc's Solwara 1) having been identified in Conductor 1, the first lens, with the boundaries in the drill core very sharp between the chalcopyrite and the clayey sediment (since altered to a volcaniclastic).
