Northern Vertex Intercepts 6.1 Meters @ 9.77 gpt Gold & 36.28 gpt Silver in High-Grade Ruth Vein Located Parallel to the Moss Open Pit Gold and Silver Mine in NW Arizona

VANCOUVER, Sept. 9, 2020 - Northern Vertex Mining Corp. (TSXV: NEE) (OTC: NHVCF) (the "Company" or "Northern Vertex") is pleased to announce additional high-grade gold and silver drill results have been received from its multi-phase drilling and resource expansion program (the "Program") at the Moss Mine in NW Arizona. Most notable results include:

• Drilling confirms continuity of Ruth Vein mineralization with the potential for high-grade ore shoots running parallel for 500+ meters alongside our current producing flagship Moss Mine Central Pit.
  
• AR20-313R intercepts 6.1 meters @ 9.77 gpt gold and 36.28 gpt silver.
  
• Hole AR20-313R is located 160 meters to the northeast of Hole AR20-286R, which intercepted 15.2 Meters of 9.11 gpt gold and 85.99 gpt silver Including 6.1 meters of 21.8 gpt gold & 211.48 gpt silver; which included 1.5 meters of 69.3 gpt gold (2.02 ounces of gold) & 716 gpt silver (see NEE news release dated August 12, 2020).
  
• Two rigs are currently supporting the multi-phased exploration and resource expansion program.
  
• Ruth High-Grade intercepts are typical of mineralized shoots mined in the Oatman District located in NW Arizona.

Ken Berry, President & CEO stated: "We are very pleased to report further high-grade gold and silver results from our ongoing drilling and resource expansion program on Moss. Paramount to the success of our current program, drilling continues to indicate continuity of the rapidly evolving high-grade Ruth vein structure, which runs parallel to our currently producing Moss Mine vein structure and has been traced for 500 to 700 meters on surface. Based on our advancements to date, we fully expect the Ruth vein structure to play a vital role in our new updated resource and mine plan. In addition to the exciting news from the high-grade Ruth Vein results, we remain equally enthused with our ongoing gold and silver results at Gold Bridge. The successful Gold Bridge results will enable us to achieve an even more efficient and profitable mine as we look to combine the currently active Centre pit and West pit areas within the next year."

Adds Mr. Berry: "As Arizona's largest pure gold and silver producer, health and safety and social responsibility has always remained our number one priority. I would like to personally thank our entire team and our contractors as we continue to work safely and prudently in our host community of Bullhead City, Arizona during these unprecedented times."

Current drilling advancements for Northern Vertex follows a period of sustained operational success for the Moss Mine in Arizona that includes three consecutive quarters of increased gold production and a record $18 million in revenues for the quarter ending June 30, 2020 (see NEE News Release dated August 6, 2020).

The Ruth Vein

The Ruth Vein hosts high grade mineralized shoots common to those in the Oatman District as evidenced by historical mine records and intercepts in drill holes AR20-313R and AR20-286R. The Oatman high grade shoots located at the United Eastern Mine hosted ore bodies as large as 770,000 ounces in only 700,000 tons (a grade of 1.1 ounce per ton). The Ruth Vein has the potential to materially increase the Moss Mine resource base with high grade ounces.

The 2020 drilling program has successfully intercepted the Ruth Vein in 25 holes over a strike length of more than 500 meters and to a vertical depth of approximately 198 meters below the original topography (click to view: Plan Map). Assay results have been received on 16 holes drilled, with six holes reported August 12, 2020. Drilling results for 10 new holes received since August 12^th are provided below.

Assay results received to date show gold grades up to 69.3 gpt gold and 716 gpt silver. Without the two highest gold grades encountered this year (69.3 gpt gold and 25.2 gpt gold), the Ruth Vein and adjacent stockwork averages 1.85 gpt gold and 8.56 gpt silver over an estimated average true thickness of 14.4meters meters).

As previously released, AR20-286R intersected 15.2 meters of 9.11 gpt gold and 85.99 gpt silver, while hole AR20-313R intersected 6.1 meters @ 9.77 gpt gold and 36.28 gpt silver. These results indicate a second high-grade ore shoot may be present along the strike of the Ruth Vein. Table 1 displays a compiled list of results received since the August 12 News Release on holes targeting the Ruth Vein.

Gold Bridge

Gold Bridge is an area between the active Center Pit, and the West Pit that is currently being pioneered. Gold Bridge is approximately 60 meters wide by about 260 meters long bounded by the Moss Vein to the north and the Ruth Vein to the south (click to view: Plan Map). Previously thought to be waste, current drilling indicates this area to contain hanging wall stockwork mineralization with an average gold grade of 0.594 gpt gold for all 2020 intercepts drilled in this area above a cut-off of 0.313 gpt gold. The area also contains localized higher-grade intercepts (up to 1.68 gpt gold).

Hole AR20-278R was drilled due south from Gold Bridge Pad 3 with a dip of -45 degree, targeting the western extension of the Ruth Vein. AR20-278R successfully intersected the Ruth Vein from 44.2-50.3 meters, containing 6.1 meters (approximate true thickness 6.05 meters) @ 0.438 gpt gold and 1.35 gpt Ag. The drill hole also intersected a zone of elevated gold grades from surface to a true depth of 6.1 meters below surface containing 9.1 m @ 0.774 gpt gold and 2.43 gpt silver from 0-9.1 meters, in the Gold Bridge stockwork zone. The drilling program has demonstrated that Moss hanging wall stockworks veining persists from the Moss Vein, south to the Ruth Vein, for approximately 260 meters.

Gold Tower

Encouraging initial results from our phase 1 drill program at Gold Tower are being received. Hole AR20-288R intercepted 0.59 gpt gold and 1.25 gpt silver over 15.3 meters, including 1.0 gpt gold and 1.93 gpt silver over 4.6 meters from 74.7 – 79.3 meters. Hole AR20-291R intercepted 2.4 gpt gold and 0.9 gpt silver over 3.1 meters near surface. These holes indicate continuation of Gold Bridge style mineralization south of West pit pioneering. Assay results for 12 holes drilled at Gold Tower are pending.

QA/QC
Samples of drill cuttings were collected by the drilling crew using a wet rotary splitter to ensure a representative sample of each five-foot interval. Field notes were recorded for each sample documenting what was sampled and how the sample was taken. Samples were collected in bags with a sample tag inserted and delivered to a secure on-site location prior to pick-up by Skyline Labs, a commercial laboratory in Tucson, Arizona. Skyline Labs is an ISO 9001:2008 qualified assay lab that uses and makes available internal assaying controls. Quality control consisted of one certified gold standard, one blank, and one duplicate sample inserted into every 20 samples submitted to Skyline Laboratories.

At the lab, rock samples are dried, crushed and pulverized to 85% passing through a 200-mesh sieve. The pulps are assayed for gold using a 30 g split, Fire Assay (FA) and Atomic Absorption (AA) finish. Over limit assays for both gold and silver (10 gpt for gold and 100 gpt for silver) were rerun using a gravimetric procedure. Rejects and pulps are stored at Golden Vertex's warehouse in Bullhead City for future reference.
