Red Eagle Mining Corporation is pleased to provide an update on operations at the Santa Rosa Gold Project, Antioquia, Colombia.
Underground development at the San Ramon Gold Mine continues to advance according to plan with 383 metres in November and 4,876 metres completed year-to-date. Development during November was primarily focused on secondary access ramps and attack ramps on levels -125, -150, -175 and -200 metres, measured from surface.
San Ramon currently has eighteen working attack ramps, with ten in production (with 34 active production faces), four completed and ready for production and four in development. Stope mining operations continued to ramp up ahead of schedule in November with 6,086 tonnes at 7.1 grams per tonne gold mined and stockpiled during the month and 10,459 tonnes at 6.8 grams per tonne gold stockpiled in total. Prior to the planned mill start-up in January 2018, Red Eagle Mining expects to have stockpiled 21,000 tonnes of ore.
As a result of improved ground conditions in active mining areas, stope mining length has been increased from 50 meters to 65 meters and attack ramps have been reduced in length by an average of 30 meters with the secondary ramps now being driven closer to the shear zone. Updated ground support, drilling and blasting procedures have been successfully implemented resulting in greatly improved ground conditions, lower costs and reduced dilution. Stope mining operations are currently utilizing crushed mine waste as backfill with positive results while testing continues on paste and hydraulic fill alternatives.
