Northern Vertex Announces Amended and Updated Resource Estimate for Moss Mine Gold-Silver Project

Northern Vertex Mining Corp. (the "Company") (TSX VENTURE:NEE) announces that,
as a result of a review by the British Columbia Securities Commission, the
Company is issuing the following news release to correct and update the recent
disclosure related to the Company's Moss Mine Gold-Silver Project resource
estimate. The Company retracts the resource estimate contained in news release
of February 19, 2013 which should not be relied upon for any purpose. That
estimate reflected the Company's initial attempt to estimate the magnitude of
the error discovered in the September 2012 resource model. Based on additional
information and ongoing analyses related to the Company's preliminary economic
assessment work, the Company is now in a position to provide an updated resource
estimate which has been completed in accordance with the requirements of
Canadian National Instrument 43-101 (Disclosure Standards for Mineral Projects).



The new resource estimate for the Moss Mine Gold-Silver Project includes:



--  12,611,000 tonnes of Measured Resources with an average grade of 0.85
    grams/tonne Au and 9.10 grams/tonne Ag, or 1.03 grams/tonne gold
    equivalent ("AuEq") 
--  9,978,000 tonnes of Indicated Resources with an average grade of 0.60
    grams/tonne Au and 6.68 grams/tonne Ag, or 0.73 grams/tonne AuEq 
--  22,589,000 tonnes of Measured and Indicated Resources with an average
    grade of 0.74 grams/tonne Au and 8.03 grams/tonne Ag, or 0.90
    grams/tonne AuEq 
--  3,957,000 tonnes of Inferred Resources with an average grade of 0.57
    grams/tonne Au and 6.65 grams/tonne Ag, or 0.64 grams/tonne AuEq



To reiterate, the Technical Report dated October 25, 2012 effective date
September 10, 2012 should not be relied upon and a new, updated, Technical
Report, incorporating a Preliminary Economic Assessment, will be filed on
www.sedar.com within approximately ten days. It will also be available on the
Company's website at www.northernvertex.com.


The new NI 43-101 Mineral Resource Estimate includes 418,760 AuEq oz of Measured
Resources with average grade of 1.03 grams/tonne AuEq, 234,840 AuEq oz of
Indicated Resources with an average grade of 0.73 grams/tonne AuEq and 82,020
AuEq oz of Inferred Resources with average grade at 0.64 grams/ tonne AuEq. The
new, updated, numbers are detailed in the table below.

--  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. 



The new, updated, Moss Mine Gold-Silver Project Resource Estimate was prepared
by Metal Mining Consultants Inc. ("MMC") (formerly Scott E. Wilson Consulting,
Inc.), Scott E. Wilson and Dr. Stewart D. Redwood, FIMMM, both Qualified Persons
as defined by NI 43-101 for those who have prepared or supervised the
preparation of the scientific and technical information contained therein. CDM
Smith, International Consulting Engineers independently retained by the Company,
has confirmed they have reviewed and verified the new, updated, Resource
Estimate. The corrected and updated resource estimates will be incorporated into
a new NI 43-101 compliant technical report which will include a Preliminary
Economic Assessment of the Moss Mine Gold-Silver Project co-authored by CDM
Smith and MMC. 


The new, updated resource disclosed in this news release is based on all
technical information available to MMC as of March 5, 2013, the new "effective
date", and has allowed for better geological interpretation of the Moss Mine
Gold-Silver Project deposit. 


New technical information incorporated in the new estimate includes the following:



--  Drill hole information from 328 additional drill holes 
--  Drilling density has been increased to approximately 15-30 meters in
    most parts of the deposit, thereby resulting in increased confidence in
    the geology required to move inferred mineral resources to measured and
    indicated mineral resources 
--  Approximately 8,000 additional meters of drilling 
--  Increase in maximum intercepts used in estimations from maximum 3
    intercepts to maximum 10 intercepts 
--  An additional 1,805 composite drill samples utilized for a total of
    7,677-5 meter composite drill samples



Dick Whittington, President and CEO Northern Vertex Mining Corp., commented, "We
have rectified the resource modeling errors previously reported. We are
confident in the integrity of the data going forward. Our new, updated, resource
model is robust and incorporates all previous as well as new drilling results
which post-date the September 2012 technical report and resource estimate. The
release of the Preliminary Economic Assessment for Phase I and Phase II is still
on target and is expected to be released in March."
