Northern Vertex Announces Moss Mine Continues To Exceed Feasibility Expectations During Ramp Up To Commercial Production

VANCOUVER, June 19, 2018 /CNW/ - Northern Vertex Mining Corp. (TSXV: NEE) (OTC-Nasdaq Intl.: NHVCF) (the "Company" or "Northern Vertex") is pleased to announce the Company continues to meet or exceed the design expectations of the NI 43-101 Technical Report - Feasibility Study issued on July 13, 2015 for Northern Vertex's Moss Mine, located in NW Arizona. 

Kenneth Berry, President and CEO, stated: "I am pleased to provide this positive update on the performance of the Moss Mine during our commissioning phase. Our operational crews continue to implement numerous optimization measures which have improved production and performance of the mine. The mine is operating to feasibility expectations and often exceeds our forecasts. I look forward to providing additional updates as we transition to Commercial Production over the coming months."

Operating Results for May 2018 and Year to Date as of May 31, 2018

  • Gold production in May 2018 of 1,276 ounces of gold and 3,556 ounces of silver, a considerable increase month over month as the ramp up to commercial production continues to exceed feasibility expectations.
  • Mining is expected to continue to ramp up as N.A. Degerstrom brings in 70-ton haul trucks to replace the 40-ton articulated trucks currently on site.
  • Crushing Crew recorded a "best shift" of 5,297 tonnes and "best day" of 8,261 tonnes of ore crushed and stacked. This compares to the Feasibility Study projections of reaching 3,500 tonnes per day ("tpd") in month seven from start-up of the mine followed by a tonnage increase to 5,000 tpd in month thirteen through the end of the mine life. The Company cautions that "best day" is not the average, however, it is indicative of the high quality of the plant, the personnel and management involved and the teamwork that made it all come together well ahead of schedule. Furthermore, since startup of the Moss Mine the Company's crushing crew has consistently improved the through put as measured by tonnes crushed per shift as well as tonnes crushed per operating hour.
  • Ounces processed are being recovered at a faster rate than the 100-day leaching cycle time period as set out in the Company's feasibility study.
