Symbol Mining Ltd. defined the Aisha deposit as its second zinc-lead project at its 60%-owned Imperial property in Nigeria, along with the Macy deposit.
The company is undertaking a development study at Macy while negotiating a mining contract and is on track to transition into open cut mining by mid-2018.
Symbol Mining said March 26 that assays received to date from a recent 3,500-meter drill program at Aisha had outlined a system of zinc-lead veins and lenses, defining three to five mineralized veins across the width of mineralization and over a strike length of more than 800 meters.
Drill highlights include 2 meters at 18.49% zinc and 1.82% lead from a depth of 75 meters and 2 meters at 29.72% lead and 4.56% zinc from 44 meters. Drilling is scheduled to resume at Aisha in late April.
Aisha and Macy are about a kilometer apart and both host massive sulfide mineralization, which is expected to simplify the production of direct shipping ore.
A recent update at Macy resulted in 85% of the resource being classified in the indicated category, compared to 70% previously. At a 2% zinc cut-off grade, Macy hosts indicated and inferred resources totaling 132,700 tonnes at 18.3% zinc and 2.1% lead, for 24,284 tonnes of contained zinc and 2,787 tonnes of contained lead.
