[{"type":"text","content":"Metallurgical Test Work Yields Excellent Recoveries and Concentrate Grades at Pegmont Lead — Zinc ProjectVancouver, British Columbia--(Newsfile Corp. - March 6, 2017) - Vendetta Mining Corp. (TSXV: VTT) (the \"Company\") is pleased to announce the initial metallurgical test work on the Pegmont Lead-Zinc project from the Burke Hinge Zone open pit target (BHZ) and the high zinc grade Zone 5 underground target. Using industry standard test work the initial flotation tests produced separate lead and zinc concentrates using bench scale batch (open cycle) flotation. Tests were performed by ALS Metallurgy, in Burnie Tasmania, under the supervision of Vendetta's consulting metallurgist Mr. Geoff Richmond. Three composites from sulphide mineralization at BHZ, and Zone 5 Lens B and C were processed. A fourth test was performed on transition mineralization at BHZ. In all cases, separate marketable lead and zinc concentrates were produced. Table 1. Composite Details, Overall Recoveries and Concentrate Grades.

BHZ transition sample was prepared using half core HQ. All sulphide composites included barren hangingwall and footwall country rock to simulate mining dilution. The BHZ transition test did not include dilution.Pre-concentration method investigated included magnetic separation and heavy media separation. These were performed on the BHZ sulphide and Zone 5 Lens B composites, results indicate that no meaningful advantage can be gained from pre-concentration.All composites were ground to P80 passi...
