 Tango – African Star Minerals (“ASM”)

During the course of the year, Tango through its local subsidiary, ASM, acquired an additional pan plant (the “Plant”) with a 120 tonne per hour (“tph”) capacity to be used to process Tailings left on site from previous mining operations. The Plant began commissioning in June 2018 and is ready to begin processing material. Start of production has been delayed due to the 260 KVA diesel generators that was purchased and has had to be replaced, delaying commissioning of the operation. New piping and water pipe were also purchased and are onsite and ready to be installed. A mobile screening unit and earth moving equipment will be mobilized to site to support the Plant operations and this is anticipated to occur prior to the end of 2018. ASM currently has 8 employees on site.
