Northern Vertex Announces a Preliminary Economic Assessment of the Moss Mine Gold-Silver Project, NW Arizona

28/03/2013 10:00am

Marketwired Canada


Northern Vertex Mining Corp. (the "Company") (TSX VENTURE:NEE) announces the
results of a preliminary economic assessment ("PEA") for its Moss Mine
Gold-Silver Project, Mohave County Arizona, USA. The PEA is based on the
recently announced updated resource estimate and is contained in a NI 43-101
(Disclosure Standards for Mineral Projects) compliant technical report
co-authored by CDM Smith, Inc. ("CDM") and Metal Mining Consultants Inc. ("MMC")
dated March 13, 2013 (the "Technical Report"). 


Northern Vertex has the right to earn a 70% interest in the Moss Gold-Silver
Property from Patriot Gold Corp. by spending $8 million and preparing a
feasibility study. The Company has spent $5.6 million to date. Subsequent to the
Northern Vertex earn-in, funding of the project by the participants will be on a
70:30 proportional basis.


Preliminary Economic Assessment Highlights: 

This PEA evaluates the economics of open pit mining and heap leach processing
for the Moss Mine Gold-Silver Project. All figures are in USD unless otherwise
stated, are based on a gold price of $1,500/oz and are on a 100% basis.
Highlights are as follows:

Dick Whittington, President and CEO Northern Vertex Mining Corp, commented, "The
results from this Preliminary Economic Assessment are positive and show the
potential economics associated with the Moss Mine Gold-Silver Project. A Pilot
Plant operations phase (Phase I) is recommended by the Technical Report and will
precede operations (Phase II). If the Pilot Plant is successful and lab
metallurgy is proven in the field, we can assess the feasibility of moving
forward with operations subject to required financing. We believe that there
continues to be upside in maximizing results from the in-field operations, from
possible pit expansions as a result of the mine exploration programs and of
course, possible Mine Life Extension or Expansion (Phase III). We look forward
to advancing the project towards mine operations and to creating both
shareholder value and stakeholder value in the Bullhead City Region".


Key PEA Parameters and Conclusions:

The Company's 3 Phase Mine Development Plan, as outlined in previous news
releases, is designed to move the project forward from conceptual design and
laboratory test work to on-site pilot plant testing (Pilot Plant - Phase I) and
then onto operations (Phase II). Phase II is independent from Pilot Plant -
Phase I, and will only proceed if Phase I is successful. Phase III is conceptual
only, will depend on the success of Phase II, and so is not included in the PEA.
Phase III would involve mine life extension and or expansion.


A summary of the key parameters and results of the PEA follow.

New National Instrument 43-101 Technical Report on Resources:

This Technical Report estimates the NI 43-101 compliant Mineral Resources at the
Moss Mine Project. The updated resource estimate was prepared by Dr. Stewart D.
Redwood, FIMM, and Scott Wilson of MMC and was outlined in the News Release
dated March 12, 2013. The summarized resource estimate in the table below
includes 12.6 million tonnes (AuEq of 1.03 g/t) of measured resources and 9.98
million tonnes (AuEq of 0.73 g/t) of indicated resources (aggregate average:
22,589,000 tonnes at 0.90 AuEq g/t) for total measured and indicated AuEq oz of
653,600 (537,000 Au oz and 5,830,000 Ag oz). It is important to note that
mineral resources described herein are not mineral reserves and, as such, do not
have demonstrated economic viability.

--  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- five 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.

Resource Estimates for Phase III - Mine Life Expansion / Extension:

The anticipated operating period for Phase I is 15 months and for Phase II is 5
years, including development and construction. Phase II will only proceed upon
the successful completion of Phase I. 


Pilot Plant - Phase I and operations - Phase II measured and indicated resources
encompass 265,000 of the total 654,000 ounces gold equivalent of global
resources estimated by MMC. The remaining resources (389,000 ounces gold
equivalent) appear to be generally located beneath and west of operations -
Phase II resources and would be available for mining at a later date. For
further details on both tonnes and grade of Au and Ag separately, please see
previous tables.


It should be noted that the Phase I and Phase II resources described are
physically constrained to that which can be reasonably extracted by limiting
mining and related facilities to patented - or private - land. The conceptual
Phase III mine plan would be pursued without the physical constraint of limiting
operations to patented land and will require normal course approvals from
various US governmental departments and mining authorities. 


Based on development of the initial resource solids containing the Phase I and
Phase II resource, the mining extraction recovery rate of the in-situ resource
is anticipated to be 100 percent. 


As mentioned above, upon the completion of Phase II, 389,000 oz AuEq will
remain. Extending mining and processing operations onto unpatented land by
mining along strike and to depth has the potential to extend the life of the
mine. This will be the subject of further investigation concurrent with Phase II
operations. This investigation will incorporate permitting, technical, economic,
and financial elements into one or more pre-feasibility and/or feasibility
studies.


Metallurgy:

Overall metallurgical data shows that ore from the Moss Mine Gold-Silver Project
is readily amenable to agglomeration - heap leach cyanidation processing. Column
test recoveries obtained from the bulk samples, finely crushed using rolls
crushers and agglomerated using cement as a binder, ranged from 75% to 84.6% for
gold and from 61.3% to 76.6% for silver. Recovery percentages are summarized in
the table below:

Gold extraction was still progressing when column leach tests were terminated
for purposes of completing the PEA and is expected to increase further with a
longer leach cycle. Preliminary data from an ongoing column leach test indicate
that the low grade mineralization will be amenable to agglomeration/heap leach
cyanidation processing after rolls crushing to a 95%-1/4" feed size. Use of
industrial scale high pressure grinding rolls (HPGR) has the potential to
improve liberation and yield higher recoveries. 


The favorable results from the labatory metallurgical testing provide the basis
for proceeding with the proposed field testing Pilot Plant - Phase I.
Metallurgical data from the Pilot Plant program will be collected and analyzed
for use in the design of operations - Phase II. Both higher grade and lower
grade mineralized rock is expected to be tested in the Pilot Plant. Although
positive results have been obtained to date, additional metallurgical test work
will be required. Consequently, recoveries used in the PEA have been scaled back
to 75% for Au and to 55% for Ag.


Exploration:

The Preliminary Economic Assessment recommends a continued exploration program
to further delineate the mineralization at the Moss Gold-Silver Project. The
limits of mineralization are still open at depth and to the west. The
recommended drilling program includes additional drilling of 2,200 meters and
associated costs are outlined in the table below:

---------------------------------------------------------------------------



Various other sensitivities have been carried out assessing the effects of:



--  An increase in capital cost by $10 million 
--  An increase in operating costs by 20% 
--  An increase in gold and silver recovery rates to match higher recovery
    rates in lab results 
--  An increase in costs of diesel fuel for power production by $1 per
    gallon 
--  A decrease in capital equipment costs by 25% by way of using used
    equipment instead of new 
--  An increase in pit slope from 55 degrees to 65 degrees 
--  A decrease in delay of NSR receipts from 25% to 10% 



The results are attached as Appendix 1 and indicate the robust nature of the
Moss Mine Gold-Silver Project.
