[{"type":"text","content":"Southern Silver Increases Value of Concentrates in Locked-cycle Test workVancouver, British Columbia--(Newsfile Corp. - January 16, 2020) - Southern Silver Exploration Corp. (TSXV: SSV) (\"Southern Silver\") reported today that the company continues to de-risk the Cerro Las Minitas project with the completion of the latest round of metallurgical test work. Results confirmed a sequential process flowsheet able to produce marketable copper, lead and zinc concentrates from a representative composite of the Skarn Front deposit, significantly increasing the marketability and projected value of the resulting lead and zinc concentrates compared to earlier batch testing. These results are highlighted by a 94.7% zinc recovery grading 54.0% Zn in the zinc concentrate and grades of 5,504g/t Ag and 65.1% Pb in the lead concentrate. Silver strongly partitions into the lead and copper concentrates for a combined 83.8% Ag recovery into concentrates that traditionally receive favourable payable terms.This round of test work utilized a more robust protocol than the earlier reported batch testing (see NR-10-18; September 19, 2018), resulting in significant upgrades of both the lead and zinc concentrates and greater confidence in the recovery and grade projections. Further variability test work on the Skarn Front deposit continues in order to determine the broader parameters for metallurgical recoveries and concentrate values. Results from this additional test work are still pending.President, Lawrence Page Q.C. stated \"The results of this most recent test work demonstrate a process to derive increased value from silver, lead and zinc, the prevalent metals identified in the CLM deposit. This is a significant milestone in that we have advanced a viable Cu-Pb-Zn processing flowsheet with no fatal flaws and increased the overall value of the resulting concentrates compared to the earlier batch test work.\"Test Work DetailsThe test work was conducted on behalf of Southern Silver by Blue Coast Research of Parksville, British Columbia, and improves on earlier batch testing (see NR-06-18, May 14, 2018 and NR-10-18, September 19, 2018) that generated high-grade lead and zinc concentrates from the Blind-El Sol deposits and high-grade lead, zinc and copper concentrates from the Skarn Front deposit. The current test work program comprises:locked-cycle and b...
