Long-hole mining at the Sigma mine is relatively recent, so very few historic details are available. Dilution was a major problem with this type of mining due to the conception parameters initially used: stope dimension (hydraulic radius), drilling length, over-excavation of sub-levels, follow-up of the vein.
