Many unidentified copper species - numerous supergene copper species in various stages of transition/reduction/enrichment with copper contents ranging from 75-94% Cu (mineralogical analysis required to accurately determine species).
The supergene zone in Las Minerale is without doubt unique in modern day mining and will provide sufficiently high grades suitable to generate direct shipping ore (DSO) product.
Plans for early revenue are being finalised, based on two product options;
1. Crushing and scalping of high-grade coarse native copper ore, +40mm to produce a high-grade premium product (as generated in recent trial crushing ~95% copper concentrate), with the remaining product after scalping (including smaller native copper, native copper in rock-matrix, chalcocite and other supergene copper species), to be shipped as a crushed DSO product. The balance of the native copper to be processed through the mineral processing plant on completion and commissioning in 2014.
2. Ship DSO ore straight from the pit (uncrushed) for toll treating.
Without crushing and/or homogenising the co-mingled coarse native copper and supergene ore species, estimating copper grade of the DSO product is challenging.
All evidence at Rocklands to date suggests significant underestimation of copper grades during sampling and assay when coarse native copper is present.
