[{"type":"text","content":"ScoZinc Announces Ausenco's Mill Optimization Study Results and a Corporate UpdateHalifax, Nova Scotia--(Newsfile Corp. - February 5, 2020) - ScoZinc Mining Ltd. (TSXV: SZM) (\"ScoZinc\" or the \"Company\") is pleased to report that Ausenco Engineering Canada Inc. have completed their mill optimization study at our Scotia Mine that supports the possibility of a low-cost and low-risk return to full scale production.The President and CEO, Mr. Mark Haywood, stated, \"Ausenco's detailed review of our processing operations over the last few months has confirmed our strategy that a low mill refurbishment cost is realistic and achievable within a reasonable time frame. Combined with the recently announced new Mineral Resource Estimate, which almost doubled the Scotia Mine's mineral resources, we are encouraged that the upcoming Pre-Feasibility Study will be a significant improvement on the past Preliminary Economic Assessments. We are also pleased to update our shareholders on a number of other corporate activities.\"Corporate Update:Ausenco Engineering Canada Inc. (\"Ausenco\") mineral processing trade-off technical study determined that the mill contained a number of production and maintenance bottlenecks whose removal will contribute to increasing the efficiency of the mill. Such bottlenecks included, inadequate grizzly design, inability of primary and secondary crushers and screens to correctly reduce rock sizes for efficient grinding, excessive dust generation inside the mill, undersized screens and general crushing circuit throughput restrictions, fine ore bin ore freezing and maintenance constraints, grinding circuit throughput and sizing constraints, re-grind mill disconnection, flotation circuit overload and poor particle separation and recovery, excessive concentrate moisture due to poor drying circuit system, insufficient and unreliable power supply, and insufficient and unreliable water supply. In evaluating the bottlenecks, Ausenco determined that a number of low-cost improvements could be made during a relatively short refurbishment period to significantly de-risk the processing operations. The main process flow improvements include the following:Addition of a two-stage crushing on the Run-Of-Mine pad to eliminate excessive dust and improve oversize handling, throughput and blending controls;Upgrades to fine ore bin with ...
