South Star Mining Corp. announced that it has received the complete assay results from the 2018 exploration program (Program) at its Santa Cruz Graphite Project (Project) in Bahia, Brazil. The field investigations portion of the Program was completed in December of 2018. The Company's previously released PEA reported Indicated Resources of 14,990,400 tons @ 2.70% Cg and Inferred Resources of 3,572,100 tons @ 2.90% Cg. With the goal of moving towards production in 2020 using a trial mining license and a pilot plant, South Star's 2018 exploration program was focused on the São Manoel and São Rubens targets of the Project. The Program included surface trenching along with 531.65 meters of diamond (8 holes - HQ) and 1,288.25 meters (32 holes) of reverse circulation (RC) drilling. The majority of the 2018 Program concentrated along 700 meters of strike at the São Manoel target, where previous exploration programs indicated significant graphite mineralization. The Program was designed to test lateral extents and depth of mineralization along this target, and completed work included all the trenching, 7 diamond holes, and 27 RC holes. The São Rubens portion of the Program was focused on upgrading the resources in that area to allow for future mine planning flexibility and consisted of 1 diamond hole and 5 RC holes. The Company currently plans to incorporate the results of the Program into an updated resource estimate, coupled with final metallurgical and dry stack tailings testing, to be completed in second quarter of 2019. Engineering, testing, environmental and licensing activities are on-going with completion, including the delivery of a prefeasibility report, scheduled for third quarter of 2019.
