November 11th, 2019,Vancouver, B.C. - Northern Vertex Mining Corp. (TSX.V: NEE)(OTC Nasdaq Intl.: NHVCF) (the “Company” or “Northern Vertex”) is pleased to provide the following operational update on its 100% owned Moss Gold Mine located in NW Arizona, USA.

Kenneth Berry, President and CEO, states: “Concurrent to delivering our strongest quarter since announcing commercial production in September 2018, the Company continues to implement improvements in several areas at Moss to reduce costs and increase production performance. We are seeing positive results in the recovery rate of both the Merrill Crowe plant and heap respectively. Also, the use of backhoe loading, and better blast control is showing immediate improvement in grade control and tonnage throughput. These achievements made over the last 6 months have allowed us to shift focus on cost reduction and resource expansion.”

Oversized Ore Stockpile 

During the first quarter, the Company brought in a portable crusher for a five-week period to eliminate the stockpile of oversized material. This was necessary to better reconcile mined to modeled ounces to pad and thus better understand and control dilution. The Company estimates that up to 1,818 contained ounces of gold and 31,516 contained ounces of silver were added to the leach pad.  

Donegan (MCD) Drilling & Blasting

The Company brought on a new drilling and blasting contractor to reduce the amount of oversized rock being generated from mining activities going forward. In the first few weeks of blasting, fragmentation is excellent; and the oversized material has been significantly reduced, increasing crusher throughput and ounces to the pad. 

Exploration Drill Update

To date,25 drill holes have been completed from an expected 29-hole reverse circulation drill program totaling approximately 4,300 meters.  The infill drill program is being conducted at the West Pit, on the western end of the planned Phase II pit, to confirm grades and potentially extend the boundaries of mineralization. The West Pit infill drilling program is expected to be completed by the end of November; assay results should be received late December.

Stacking and Leaching Plan 

Based on monthly column leach tests, a heap leach and stacking plan was developed resulting in a significant reduction in the timeline of our primary and secondary leach cycles. The primary leach cycle now yields 60% recovery for gold within 45 days versus the feasibility timeline of 150 days; whereas the secondary leach cycle is estimated to recover over 82% of the gold within 120 days versus the feasibility estimate of 240 days. This means the production of more ounces in less time. 

Process Production at the Merrill Crowe Plant

Changes in the Merrill Crowe Plant (MC) bring it into industry standard. The MC Plant is now operating at or above industry standards with gold recoveries running 97+% and silver recoveries of 98+%. Plant flow has been consistent and topped out at 2350-2400gpm.

Water Balance

Better conservation and operational practices have allowed the site to be self-sufficient since June 2019, eliminating the need to truck water to site. A significant cost saving. Additionally, a new well, #21, was brought online in late October and provides the site with a buffer against any demand growth beyond current planning periods and the ability to rest and recharge wells at current demand. 

Metallurgical Test Work

The metallurgical test work at site includes daily, weekly and monthly testing of live stacked material to flag any variability in metallurgical performance, confirm recovery curve(s) used in revenue modeling and establish solution chemistries that optimize gold and silver recovery. No significant metallurgical variability has been witnessed since this disciplined testing program has been in place. 

Permitting Update 

The Company continues to work on completing the Environmental Assessment (EA) portion of Company’s Mine Plan of Operations (MPO) to expand mining, leaching and exploration onto public BLM land which is expected to extend mine life by approximately 5 years. Concurrently, amendments to the Aquifer Protection Permit, Air Quality Permit and Mine Reclamation are being prepared for submission to the Arizona Department of Environmental Quality with the assistance of consultants Stantec, CDM Smith and Wood PLC respectively.  The Company hopes to receive approval for the Phase III MPO in the first calendar quarter of 2020.

Powerline Update

Northern Vertex continues to advance discussions with Mohave Electric on the construction of the powerline to the Moss site. Once completed, the powerline is expected to reduce diesel emissions to the environment by up to 90% and provide significant cost savings to the Company of up to $200,000 per month in fuel and maintenance costs over the next several years of operation.  The powerline is fully permitted and construction ready.

Crush Size Test Work

Preliminary test-work to increase the crush size from 1/4”to 3/8”is on-going and continues to show positive results. A larger crush size to the heap pad would reduce maintenance costs and increase the tonnage and ounces being processed thus reducing costs and increasing cash flow to the bottom line.  

Human Resources

We are pleased to add Miguel Rivera as Tech Services Superintendent to strengthen our mining team and John Stefka as environmental services Manager. These two gentlemen bring a wealth of experience and knowledge that will benefit the Company in managing our mining plans and expansion efforts onto BLM land.
