Northern Vertex East Pit Expansion Drilling Intersects 21.34 Meters Grading 1.98 g/t Gold and 23.75 g/t Silver Highlighting Potential for Resource Expansion at Moss Mine, Arizona

VANCOUVER, BC, May 26, 2021 /PRNewswire/ - Northern Vertex Mining Corp. (TSXV: NEE) (OTC Nasdaq Intl.: NHVCF) (the "Company" or "Northern Vertex") a Western U.S. gold producer with district-scale exploration projects in the Walker Lane Trend, is pleased to report recent results from its multi-phase infill and resource expansion drilling program at the Moss Mine in NW Arizona. Results for this release are focused along strike to the East of the producing Moss Mine.

Key Points:

• 21.34 meters grading 1.98 g/t Gold and 23.75 g/t Silver in drillhole AR21-424R.
• 22.86 meters grading 1.32 g/t Gold and 17.43 g/t Silver in hole AR21-425R.
• Drilling indicates economically significant mineralization extends at least 140 meters from mining operations and remains open.

Northern Vertex President, Michael G. Allen commented, "High grade gold mineralization immediately along strike of the producing operation gives us confidence in our ability to expand the resource at the Moss Mine in the near term. We are consistently showing that the Moss Mine has the potential to become a much larger operation as we explore within and around the existing footprint, along with multiple regional opportunities our team has identified. Over the coming months we intend to systematically explore and expand the Moss Property to assess its full potential as Arizona's largest pure precious metals producer."

Geology East of the Moss Mine

The Moss Vein is a fault-hosted epithermal quartz-calcite vein and vein stockwork. The vein strikes slightly north of east and dips to the south. Locally, the Moss Vein develops a more northly strike.  These changes in strike are potential targets for the development of shoots of higher-grade mineralization.  This observation was noted throughout the historical Oatman District which surrounds the Moss Mine.

The Ruth vein appears to narrow yet remains open to the east of the current mine, and is considered a target of interest for further resource expansion.   

Drill Results

Assay results for 14 reverse circulation (RC) drillholes drilled from four different locations are included in this news release (see Table 1). Numerous relatively thick zones of epithermal vein-hosted gold and silver mineralization have been intersected along strike to the Moss East Pit (Figure 1 East Pit Extension Drilling Area Location Map; Figure 2 East Pit Extension Drillhole Location Map).

Significant intersections include drillhole AR20-424R which returned 21.34 meters grading 1.98 g/t gold, and 23.75g/t silver (2.30 g/t gold equivalent), including 3.05 meters grading 5.97 g/t gold and 40.05 g/t silver (6.50 g/t gold equivalent) for the Moss Vein, and drillhole AR21-425R, which returned 22.86 meters grading 1.32 g/t gold, and 17.43 g/t silver, (1.55 g/t gold equivalent), including 7.62 meters grading 3.39 g/t gold and 37.34 g/t silver (3.88g/t gold equivalent), (Figure 3 Cross Section: East Road Site, East Pit Extension Moss Vein Drilling Area).

The Moss Mine resource expansion drilling continues to intersect mineralization approximately 140 meters to the east of the existing pit rim.  Further work to expand the resource is ongoing.
