CONFIRMS CONTINUITY OF HIGH-GRADE RUTH VEIN OVER 650 METERS & REMAINS OPEN FOR 2KMS PARALLEL TO THE MOSS OPEN PIT
Northern Vertex Mining Corp. (TSX-V: NEE) (OTC Nasdaq Intl.: NHVCF) is pleased to announce additional high-grade gold and silver drill results have been received from its multi-phase resource expansion program at the Moss Mine, located in NW Arizona. Most notable results from this round of drilling include:
Ken Berry, President & CEO stated: “In addition to the success of high-grade gold and silver results from the previously untested Ruth Vein, we are extremely encouraged with the widespread mineralized intercepts encountered at the Gold Bridge and the Gold Tower zones, located directly adjacent to the producing Moss open pit mine. The recent success of our current drill program supports our objective to significantly expand the Moss Mine resource base. The positive drill results achieved from the Ruth Vein and its proximity to the Moss Vein open pit makes it an important target for further testing the possibility of additional resources, pit expansion and mine life extension.”
Ruth Vein Drilling
The Ruth Vein strikes subparallel to the Moss Vein, dips to the north into the south-dipping Moss Vein and crops out approximately 150 meters south of the active Center Pit. Click the link to view a plan map showing the location of the Ruth Vein (figure 1).
Recent drilling of the Ruth vein has focused on following up high-grade vein intercepts in holes AR20-286R and AR20-313R (see news release dated September 9, 2020); increasing the known strike length and confirming continuity of mineralization along strike and down dip of the vein. Drilling has now intersected the Ruth Vein over a strike length of approximately 650 meters; and the vein remains open both to the east and to the west. In addition to confirming continuity of narrow high-grade gold and silver mineralization in the vein as evident in holes AR20-312R returning 6.1m @ 5.18 gpt gold, 37.4 gpt silver at 94.6m and AR20-306R returning 4.6m @ 5.62 gpt gold, 57.6 gpt silver at 89.9 m; recent drilling has unexpectedly discovered thick stockwork mineralization surrounding the Ruth Vein in many places. Hole AR20-307R intersected 22.9m @ 1.107 gpt gold and 14.9 gpt silver surrounding a suspected stope mined through the vein, and hole AR20-310R drilled 18.3m @ 1.02 gpt gold and 26.5 gpt silver.
Intersection of the Ruth and Moss veins was tested by hole AR20-315R, which drilled the Ruth Vein approximately 185 meters beneath the surface and then intersected the Moss Vein at approximately 274 meters down hole. Here, very thick zone of quartz stockwork veining was encountered between the two veins and intercepted:
A north-south fence of drill holes AR20-315R, AR20-314R and AR20-313R demonstrate continuity of gold-silver mineralization along a down-dip length of approximately 274 meters on the Ruth Vein from the surface to the Moss Vein intersection.
Internal modelling indicates the intersection between the Moss Vein and the Ruth Vein may become shallower on strike to the east. Additional drilling is underway to target the untested intersection along strike. Discovery of thick mineralization along this extensive zone of structural preparation could lead to a future expansion of the Moss open pit mine to depth.
Ruth Vein Extensions
The Ruth Vein out-crop can only be traced on surface for about 170 meters along strike, however scattered historic prospect pits have exposed veining for another 320 meters to the west. Similar scattered vein exposures could be followed for about 220 meters to the east, giving the vein a surface expression of approximately 710 meters. A north-dipping vein in the hanging wall of the Moss Vein outcrops on surface east of the current pit limit, roughly one kilometer farther east of the last indication of the Ruth Vein, and extends for a minimum of 250 meters to the east. This vein is similar to the Ruth vein in width, texture, orientation, and position relative to the Moss vein. The area between the two veins is characterized by scattered veins and stockworks and likely correlates with the Ruth vein. As a result, this vein has been named the East Ruth Vein.
The Gold Tower target consists of a broad zone of stockwork veining south and west of, the West pit, which is currently being pioneered and expected to deliver ore in mid-October. Recent drilling at Gold Tower has extended stockwork mineralization further to the south and west, with several thick zones intersected in many holes, including AR20-300R, which returned:
In addition to the stockwork mineralization, some higher-grade veins have been drilled within the stockwork, such as AR20-293R, containing a vein assaying 9.15m @ 2.40 gpt gold and 2.78 gpt silver.
The Company continues to evaluate recent assay results received for the 15 holes, including 10 from the Gold Tower area and 5 holes from the Ruth Vein area, while refining the mineralization models. Drilling remains ongoing with two reverse circulation drill rigs focusing on the expansion of the Ruth Vein, stepping-out to the east and in-filling on-strike and down-dip.
Detailed Drill Results
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.
