Vancouver, BC - Northern Vertex Mining Corp. (the "Company") (TSX.V: NEE) announces assays received to date for its recently completed 15-hole, 2,527 meter exploration diamond drilling program on the Moss Mine project in Mohave County, NW Arizona. All holes were drilled on patented claims as part of the Mine Exploration Program. The program was designed to:

  • Evaluate the potential for extending the near-surface, stockwork style mineralization in the western section of the deposit
  • Test for deep extensions of the Moss mineralization below the previous deepest drilling
  • Provide additional mineral resource information from two areas of inferred mineralization near the eastern end of the planned Phase II pit

The drilling was completed as part of a recommended $1.15 million exploration program of which approximately two-thirds has now been spent. Highlights of the assays received to date are given below. To view drill location maps and related cross sections please click the following link:

  1. Widths are core lengths and are not true widths. Composited widths based on a 0.30 g/t Au cut-off grade and maximum internal dilution between above cut-off grade samples of 1.5 m
  2. Gold equivalent values are calculated as Au g/t + (Ag g/t/50) and assumes 100% recovery of both metals

Please see Tables 1 and 2 appended to this release for further results.

Assay results reported here are complete for holes AR-195, 198, 204, 205 while partial results are reported for AR-197, 199, 200, 201, 206 and 211, for a total of 10 holes. Results are pending for the remaining five holes, AR-196, 207, 208, 210 and 212, and will be reported once received. None of the diamond drill holes in this program have been included in previous mineral resource estimates (see Northern Vertex news release June 18, 2013).

Drill holes AR-204, 205, 211 and 212 were drilled in the western section of the deposit known as the Western Extension. The holes tested near surface quartz-carbonate stockwork zones that were open to the south of the evaluated mineral resource. Multiple zones of stockwork veining were encountered in AR-204, 205 and 211 all within a maximum depth of 150 meters from the surface. The results substantiate the potential of the widespread stockwork mineralization to continue to the south beyond the current limit of the mineral resource estimate.

The other eleven exploration drill holes were drilled in the central and eastern part of the Moss deposit. Eight of the holes were deep tests of the down dip extension of the Moss mineralized zone. The results from AR-195, 197, 199, 200 and 206 demonstrate that the strong development of quartz-carbonate veins, breccias and stockworks continue at depth to at least 200 meters vertically from surface. In addition, two shallow holes (AR-198 and 207) tested the Moss mineralization on two sections containing relatively widely-spaced drill holes. AR-198 cut a nearly 20 meter wide zone of mineralized veining while assays are awaited for the 3.2 meter quartz vein encountered in AR-207.

Logging, Sampling and Assaying Procedures:

The holes were drilled by Northern Vertex using HQ drill tools. The core is logged at the Company's logging facility in Bullhead City, Arizona. Nominal 1.5 meter (5 ft) samples are selected by Northern Vertex geologists, then systematically sawn in half at the site. Geotechnical measurements such as core recovery, fracturing and veining, rock quality designations (RQD's), hardness and photographic logging are performed systematically prior to sampling and assaying. The one half core sample is numbered then sealed in a bag and delivered by bonded courier to Inspectorate America Corp. in Sparks, Nevada. The other core half is retained on the site.

At the lab, core samples are dried, crushed and pulverized to 85% passing through a 200 mesh sieve. The pulps are assayed for gold and silver using a 30 g split, Fire Assay (FA) and Atomic Absorption (AA) finish. Rejects and pulps are stored at the lab for future reference.

Quality Assurance / Quality Control (QA/QC):

The Inspectorate lab is an ISO 9001:2008 qualified assay lab that performs and makes available internal assaying controls. Duplicates, certified blanks and standards are systematically introduced into the sample stream as part of Northern Vertex' QA/QC program for a total control sample insertion rate of about 10%. Periodically randomly selected pulps are sent to a third party lab for additional check assays. Control sample results are reviewed and re-assays carried out when results fall outside established criteria.

Qualified Person:

The foregoing technical information contained in this news release has been approved by Mr. Colin McKenzie, P.Geo and General Manager of Exploration for Northern Vertex, a Qualified Person ("QP") for the purpose of National Instrument 43-101 (Standards of Disclosure for Mineral Projects).


Northern Vertex has the right to earn a 70% interest in the Moss Gold-Silver Property located in Mohave County, Arizona from Patriot Gold Corp. Subsequent to the Northern Vertex earn-in, financing of the project will be on a 70:30 proportional basis. The Company paid a $500,000 upfront cash payment, and that, along with an $8 million work expenditure requirement and the preparation of a feasibility study (as defined in the earn-in agreement) are conditions of the 70% earn-in.

About Moss Mine Gold-Silver Project:

The Moss Mine deposit is an epithermal, low sulphidation quartz-calcite vein and stockwork system which extends over a strike length of 1,400 meters and has been drill tested to depths of 200 meters vertically. The Moss mineral resources as estimated in the Company's recent preliminary economic assessment as outlined in the Company's News Release dated June 18, 2013, are as follows:

Moss Mine Mineral Resource:

Resource CategoryAu Eq* (oz)Au (oz)Ag (oz)TonnesGrade
  • Gold equivalency is based on a silver:gold ratio of 50:1 and assumes 100% recovery of all metals.
  • Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources estimated will be converted into Mineral Reserves estimates.
  • Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate and numbers may not add due to rounding.
  • Resources were based on 36,805 meters of drilling in 658 exploration drill holes and 530 meters of channel sampling. There were a total of 7,677- 5 meter composite samples used in the estimation of gold and silver. MMC used Inverse Power Distance (ID3) as the preferred estimation technique for the Moss Project.
  • MMC capped gold assays, prior to compositing 5 meter samples, at 17 grams per tonne and silver at 140 grams per tonne in order to limit the effect of high grade outlier grades in the estimation of mineral resources.
  • MMC applied Industry Standards in the selection of the drill hole and assay information gathered from historic and current exploration programs in its determination of Measured Mineral Resources, Indicated Resources and Inferred Resources.
