Orinoco Gold Limited announced that the Cuca Zone rehabilitation is well under way to commence commercial production by April 2018. De-watering and remedial work is now complete and panel sampling has commenced to better understand the grade, geology and structure of the high-grade Cuca Zone. Cuca is a completely independent gold system that appears to sit 20 metres vertically underneath Cascavel. In between these two systems sits the high-grade silver prospect which remains largely underexplored. In 2014, a 2.5 tonne bulk sample was taken and delivered with an average grade of 27 g/t. This compares with recent 29 bulk samples taken from Mestre, Central and Northern zones that have averaged 38.74 g/t. Whilst there is much work to be done before the company reach commercial production in April, the company is confident Cuca can form a consistent fourth source of underground feed for the Cascavel plant.
