hope this is added to PEA - news release Sudbury, Ontario--(Newsfile Corp. - October 29, 2020) - Rockcliff Metals Corporation (CSE: RCLF) (FSE: RO0) (WKN: A2H60G) ("Rockcliff" or the "Company") is pleased to announce results from a metallurgical characterization study completed on the Bur Property. The results indicate that a selective separation of zinc and copper is feasible without the use of cyanide, and clean marketable concentrates can be made from the tested sample. Ore sorting was also successful in rejecting waste from the mineralized rock.
Mr. Alistair Ross, President and CEO commented, "The characterization testing program has demonstrated a number of important positive factors. First, the mill chemistry regime currently being considered for Tower and Rail works well on the Bur sample. A relatively simple piping change to switch the copper and zinc circuits to account for the change in volume between the two metals is all that seems to be required. In addition, ore sorting has shown the ability to significantly upgrade the mined ore by rejecting the waste rock from the mined tonnage. Results of ore sorting indicate up to 25% mass rejection to a waste stream that will be placed underground. This will have a significant impact on reducing transportation costs to the mill, lowering milling costs by not having this waste material processed in the plant - and also reducing the tailing storage capacity by keeping this rock at the mine site. The mineralization adjacent to the Bur deposit has grown significantly in strike length and remains open in all directions. This is a very important as Rockcliff looks to add additional resources to the potential mine production pipeline."
