Northern Vertex Mining Corp. (TSX-V: NEE) (OTC Nasdaq Intl.: NHVCF)  is pleased to announce, for the third consecutive month, increased gold and silver production totaling 2,868 gold equivalent ounces (2,655 oz gold and 14,940 oz silver) during May from the Moss Gold Mine, located in Northwest Arizona.  See table below for details of operating results for May 2019, April 2019 and Nine Months ended March 31, 2019.


Kenneth Berry, President and CEO, states: “We are pleased with the continued increase in gold and silver production at the Moss Mine.  Building on the achievements realized by our operational team over the past few months, yields have significantly improved and are reflected in the increased gold and silver production. In addition, we have now stacked more than 30,703 oz’s of contained gold which sits in inventory on the leach pad. Based on metallurgical work from our original 125,000 tonne pilot heap, our feasibility and from a recently established column testing program, we believe we will recover in the range of 24,000 to 26,000 ounces of gold from our heap inventory over the coming months, in addition to ounces placed on the pad each month.”

Operations Team:

Our strength is our people. Commencing in March, daily production and weekly staff meetings were implemented which have resulted in improvements in all aspects of our operation. Site safety and production goals are communicated to all employees and production data is shared in real time through daily reports and on information boards. In addition, the Company is investing in its team, with the initiation of an internationally recognized training program for all Supervisors and Managers.


The Company is also pleased to announce the following additions to our Operating Team:


General Manager


  • Joel Murphy was appointed as the Company’s new General Manager at Moss. Mr. Murphy is a proven leader, who cultivates a collaborative team approach while implementing measurable goals.

Process Manager


  • Jim Gubler was appointed to the position of Process Manager. Mr. Gubler’s experience in Merrill Crowe processing and heap leach management will be valuable to the Company. Mr. Gubler has made an immediate impact by identifying and implementing several corrective measures to the mine’s processing.


Site Maintenance and Crushing Manager


  • Kesler Morris was appointed Maintenance Manager in addition to his duties as Crushing Manager. Led by Kesler, the crushing team continues to surpass projections set out in the Feasibility Study. Preventative maintenance programs are now underway in all departments.


Chief Mine Geologist


  • Steve Sabo has been appointed Chief Mine Geologist. Steve’s guidance and leadership have been called upon throughout the early stages of development. Steve has been instrumental in reworking the current block model in order to ensure we have the most accurate grade control for future mining. As we move forward Steve plans additional improvements to the ore definition and grade control programs.


Senior Engineer


  • William Werner has been appointed Senior Engineer. William is a valued team member; whose management of the mining activities are critical to our success. William is responsible for overseeing the mining contractor and overseeing the mine plan.


Exploration Geologist

Electrical and Instrumentation Supervisor


  • John Hoefle has been appointed Electrical Supervisor. John was instrumental in identifying computer software issues with our Programable Logic Controls (PLC’s) which have plagued our clarifying filters since commissioning.



The Company and its mining contractor, NAD Degerstrom have worked hard to improve product size, highwalls, benches, pit floors, blasting, reporting and safety. All areas are showing improvement. Work continues to improve costs, availability and efficiencies.


Crushing Operations

Our crushing plant has continued to excel. Crushing, agglomeration, and stacking of ore totaled 196,803 dry tonnes, with an hourly average of 432 tonnes per hour. Waste rock was crushed for blast hole stemming material that totaled 5,279 waste tonnes. Process maintenance has been significantly upgraded with the initiation of a preventative inspection and maintenance program.


Leach Pad/ Inventory

To date we have stacked 30,703 ounces of contained gold on the heap leach pad. To confirm gold/silver inventory, the Company has trenched to a depth of 25ft each in six areas of the pad which had not been under leach for 85 days. Initial test work has confirmed there are no dry areas, channeling is not occurring, and the pad is retaining its moisture as expected. Further results are pending. The ongoing column test program (using material derived from the actual hourly crushing sample collection program) show ultimate column recoveries of 80%+ for gold and 60%+ for silver. The Column work on crusher samples and the trench work will be used to optimize and shorten the recovery curves going forward, utilizing live ore panels for testing rather than bulk samples that are used in the feasibility. Every current test being run shows that we can outperform the feasibility curve with live pad conditions set to our column testing protocols.


Merrill Crow/Processing

Our Operations Team has made significant progress in identifying and correcting issues that have hampered the process plant since start up. Modifications to the filter presses, clarifiers and vacuum pump system are underway. These changes are expected to continue to stabilize the daily performance of the plant, increase recovery and result in increased production.


Phase III Mine Plan of Operations

The MPO (Final) was submitted to the Kingman Field Office of the BLM on May 22, 2019. There has been a high level of communication between the Company’s Environmental Consultants and the BLM Resource Specialists from both the Kingman and Lake Havasu Field Offices to address, explain and mitigate concerns regarding the potential impacts of the Company’s proposed expansion onto public lands.


Qualified Person

The foregoing technical information contained in this news release has also been reviewed and verified by Mr. Joseph Bardswich, P.Eng., a director of the Company and a Qualified Person for the purpose of National Instrument 43-101 (Disclosure Standards for Mineral Projects).
