Sumitomo Metal Mining (SMM) and Sumitomo Corporation (SC) have discovered a gold, silver and antimony zone in the Monte Cristo area of the Stone Boy project in Alaska, US.
The discoveries were made as part of the drilling campaign conducted by SMM’s American subsidiary SMM Exploration Corporation (SMMEC) and SC’s American subsidiary SC Minerals America (SCMA).
Twenty seven drill holes of the 29 drill holes installed between 2008 and 2010, intersected quartz veins mineralised with gold, silver and antimony.
SMM plans to continue the drilling programme to explore mineralisations in extensions and parallel veins of the Naosi prospect and initiate infill drilling to evaluate ore resources.
SMMEC has a 95% interest in the project while the remaining stake is held by SCMA.
