Northern Vertex Mining : Intersects 28.96 Meters Grading 2.28 g/t Gold and 28.84 g/t Silver in Resource Expansion Drilling at the Moss Mine, Arizona

VANCOUVER, BC, May 18, 2021 /PRNewswire/ - Northern Vertex Mining Corp. (TSXV: NEE) (OTC Nasdaq Intl.: NHVCF) (the "Company" or "Northern Vertex") a U.S.-focused 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 presented in this release are focused on the Ruth and Moss veins immediately south and down dip of the Moss Mine Center pit.

Key Points:

• Significant intersections included 9.15 meters grading 4.90 g/t Au and 57.18 g/t Ag for the Moss vein in drillhole AR20-359R and 4.6 meters grading 4.01 g/t Au and 27.97 g/t Ag for the Ruth Vein in drillhole AR20-364R.
• The north-dipping Ruth Vein is subparallel and related to the Moss Vein
• The distance between the Ruth and Moss veins is approximately 175 meters on surface, diminishing with depth as the two veins dip towards each other, intersecting at a depth of approximately 100 meters below the south wall of the Center pit.
• Drilling indicates consistent intersections of elevated gold and silver mineralization along more than 500 meters of the Ruth Vein, approximately 100 meters south of the crest of the Moss Center pit.

Northern Vertex President, Michael G. Allen commented, "The Ruth Vein is one of the many intra-mine opportunities we have identified to optimize and expand existing Moss Mine operations. Our vision is to scale up the Moss Mine into a much larger operation by capturing these optimization opportunities, expanding resources and making new regional discoveries like we aim to do through our recently announced work at West Oatman."

Vein Geology South of the Center Pit: Ruth Vein Drilling Area

The Ruth Vein is a fault-hosted epithermal quartz-calcite vein and vein stockwork that is very similar to and was likely formed at the same time as the Moss Vein. The Ruth vein strikes slightly north of east and dips to the north towards the south-dipping Moss Vein.  The intersection of the two veins is approximately 100 meters below the south wall of the Center pit. The Ruth Vein is subparallel to the Moss Vein and has been delineated over a strike length of approximately 510 meters. The Ruth Vein ranges from less than a meter to almost 15 meters thick. When hanging wall stockworks are included, especially in the upper parts of the fault-hosted vein system, overall thickness increases to almost 30 meters in places.  The Moss Vein dips to the south at approximately 70 degrees in this area.

Resource Expansion Drilling

Assay results for 18 reverse circulation (RC) drillholes drilled from four different locations are included in this news release (see Table 1). Numerous thick zones of epithermal vein-hosted gold and silver mineralization have been intersected adjacent to the Moss Center Pit (Figure 1 Ruth Vein Drilling Area Location Map; Figure 2 Drillhole Location Map).

Significant intersections include drillhole AR20-359R which returned 28.96 meters grading 2.28 g/t gold, and 28.84 g/t silver (2.66 g/t gold equivalent), including  9.15 meters grading 4.90 g/t gold and 57.18 g/t silver (5.67 g/t gold equivalent) for the Moss Vein below the Center pit, and drillhole AR20-364R, which returned 16.76 meters grading 1.75 g/t gold, and 14.08 g/t silver, (1.94 g/t gold equivalent),  including 4.6 meters grading 4.01 g/t gold and 27.97 g/t silver (4.37 g/t gold equivalent), in the Ruth Vein to the south of and below the Center pit (Figure 3 Cross Section: Well 16 Site, Ruth Vein Drilling Area). 

The Moss Mine resource expansion drilling continues to demonstrate strong and consistent gold and silver mineralization along the Ruth vein approximately 100 meters south of the crest of the Moss mine Center pit, and in the Moss Vein approximately 100 meters below the Center pit.

Note: True thickness ranges between approximately 62% of the reported interval thickness for subvertical drilling and 99% for drilling inclined at -45 degrees to the Ruth vein. Assay data are uncapped. AuEq = Au + Ag/75. RC drilling was conducted by Boart Longyear. RC samples, collected every 1.52 m, were transported in sealed bags to Skyline Assayers and Laboratories (Skyline) in Tucson, AZ. Field control QAQC samples, including standards, blanks, and field duplicates, were inserted into the sample stream at a rate of three field control samples approximately every 20 regular samples. Gold was determined by fire-assay fusion of a 30 g sub-samples with atomic absorption spectroscopy (method FA-01). Overlimit samples of gold were assayed by gravimetric means (FA-02). Skyline Laboratories is accredited in accordance with ISO/IEC 17025:2017 and ISO 9001:2015.
