2019-07-16 / @newswire


VANCOUVER, July 16, 2019 /CNW/ - Northern Vertex Mining Corp. (TSX.V: NEE) (OTC Nasdaq Intl.: NHVCF) (the "Company" or "Northern Vertex") is pleased to announce gold and silver production totaling 2,837 gold equivalent ounces (2,580 oz gold and 18,051 oz silver) during the month June and initial results from its Heap Leach Pad Study at the Moss Gold Mine, located in Northwest Arizona.

Kenneth Berry, President and CEO, states: "We are pleased to report June production concludes our strongest quarter to date and we expect to see continued improvement during the next fiscal year. In addition, recent modifications to our Merrill Crowe facility have resulted in our single largest gold shipment of $1.2 million representing 9 days of production. Furthermore, initial Heap Leach Study results confirm feasibility predicted recoveries meaning a significant portion of the contained gold and silver inventory is expected to be drawn down in the following 2 quarters."

Leach Pad Study of Gold/Silver Inventory at the Moss Mine

The Moss Team initiated a recovery study of the heap leach pad in May 2019.  The purpose was to:

  • Confirm consistent moisture percolation throughout the pad;
  • Measure solution volume and solution grade retained in various areas (panels) of the pad, in order to determine the gold and silver inventory remaining on the pad;
  • Obtain samples for further bottle roll testing, in order to estimate the amount of gold inventory that can be recovered by re-leach; and
  • Design and implement a leach solution application plan to recover additional gold from the leach pad inventory.

Results from the first panel (known as the "Central Panel"), which contains approximately 235,000 tonnes of ore have been received.  Results show remarkable consistency in the percolation of solution, both laterally and vertically. Furthermore, the study confirms there are no dry areas, channeling is not occurring, the pad is retaining its moisture as expected and that the recoverable gold and silver in inventory will meet or exceed feasibility predicted recoveries.  The full study will include an additional 5 panels and is ongoing.

Jim Gubler, Process Manager states, "The results from the Central Panel indicates that there are approximately 5,000 ounces of recoverable gold contained in this area, of which an estimated 3,000 ounces have already been dissolved in the water held in the heap and need only to be flushed and collected." With the leach solution application plan that we have designed we are projecting that a significant portion of this gold will be recovered over the next several months, which should add to our normal monthly production."

Column Testing Program
The ongoing column test program (using crushed ore samples) is predicting ultimate recoveries of approximately 80% for gold and 60% for silver. The column test work on the crusher samples and the heap leach pad recovery study described above will be used to optimize and shorten the recovery curves going forward, utilizing live ore panels for testing rather than bulk samples that were used in the feasibility. Every current test being run indicates that we should be able to outperform the feasibility recovery curves.

Merrill Crowe/Processing
Our operations have made progress in correcting issues that have hampered the process plant since start up. Modifications to the filter press piping, clarifiers and vacuum pump system are nearing completion. We have observed a large decrease in reagent consumption and an immediate improvement in recoveries of gold and silver from the pregnant solutions.

The Company also announces that, subject to the approval of the TSX Venture Exchange, the Company intends to pay director fees to its non-management directors in the aggregate amount of C$170,000 through the issuance to non-management directors of 708,333 common shares of the Company.
