The processing of this large industrial scale bulk sample has allowed us to test various reagents, grinding sizes and recovery methods in order to work towards optimizing recoveries of gold, silver, lead and zinc ” states Señor Antonio Berlanga, CEO of the Company, and although the first shipments of lead and zinc concentrates have produced reasonable cash sales as outlined above, subsequent shipments of lead and zinc concentrates are expected to command even higher sale prices per tonne based upon the assay results obtained in the Andes Mill laboratory as recovery techniques were improved and perfected towards the end of processing the complete 3,500 tonnes industrial scale bulk sample.
