VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 07/04/13 -- Northern Vertex Mining Corp. (the "Company") (TSX VENTURE: NEE) is pleased to provide a construction update on its phased project development plans for the reactivation of the Moss Mine Gold-Silver project located in Mohave County, Arizona, USA with highlights as follows:

-- Amended Technical Report and Preliminary Economic Assessment ("PEA") reconfirmed key metrics and recommendations, including continuation of Pilot Plant - Phase I construction and economics of Operations - Phase II-- Engineering, Procurement and Construction Management contract awarded-- Construction of pilot plant ponds and process facilities - Phase I underway-- 700 foot x 300 foot leach pad completed-- Initial loading of fine crushed (95% -1/4 inch) agglomerated mineralized material achieved June 28, 2013, ahead of schedule-- Target date for initial treatment of solution July 18, 2013-- Operations team strengthened



Amended Project Economics:

The Company filed an Amended Preliminary Economic Assessment on June 18, 2013 (please see News Release dated June 18, 2013) reconfirming the principal conclusions of the original PEA. Highlights of the PEA economics for Phase II (at $1500 Au and $30 Ag) are as follows:

-- IRR of 117.9% (pre-tax, pre-royalty)-- NPV of US $110 million (pre-tax, pre-royalty) (at 5%)-- Payback of 15 months (pre-tax, pre-royalty)-- Capex of US $26.6 million-- Cash costs of US $490/oz



Recommendations include the continuation of current activities on the Pilot Plant - Phase I and the advancement of project economics including conducting Pilot Plant operations to further evaluate test mining, heap leach processing and gold and silver recovery.

The Company reiterates that the Amended PEA is preliminary in nature, and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and that there is no certainty that the preliminary economic assessment will be realized.

Construction Commencement of Pilot Plant - Phase I:

Following Board approval, construction commenced May 1, 2013 on the infrastructure necessary to carry out pilot scale open pit mining and heap leach processing of an aggregate of approximately 90,000 tonnes of mineralized rock. The Pilot Plant leach pad, designed to test the economic and technical viability of heap leaching finely crushed, agglomerated material, is approximately 700 feet in length and 300 feet wide. The phase I pit will be surface mined at a strip ratio of 0.79:1 and a production rate of 1,000 tonnes of mineralized rock, crushed to 95% -1/4 inch, per day. All activities will be restricted to patented property.

A contract has been signed with CDM Constructors Inc., a division of CDM Smith, for the Engineering, Procurement, and Construction Management (EPCM) of the Moss Mine Gold-Silver Project, Phase I, including oversight of the design and construction of the Phase I heap leach pad, process ponds, canopy structures and pumping systems. Engineering has been advanced from a 30% completion level to approximately 60% completion and is now supporting the design-build construction effort that is underway, including procurement of equipment, supplies and subcontractors.

JDS Energy & Mining Inc. has been appointed as the "owner's representative" and is on site to oversee all EPCM and related activities, to ensure the Moss Mine Gold-Silver Project remains on time and on budget and to ensure adherence to the high level of safety standards set by the Company.

Mining activity and processing operations for Pilot Plant - Phase I will be carried out under the control of Northern Vertex. Official bid packages for both mining and processing were sent out and tenders were analyzed and narrowed down on the basis of competitiveness, competency and project suitability.

Tri-R Construction, headquartered in Bullhead City, Arizona was awarded the contract for mining and processing operations for Phase I which includes pit development, drilling and blasting, loading and hauling of mined material as well as roads and leach pad development, waste rock hauling and crushing of mineralized material to 1 inch. Arizona Drilling and Blasting, Tempe, Arizona was awarded a subcontract from Tri-R for the ongoing drilling and blasting of phase I material. FNF Construction out of Tempe, Arizona has been awarded the subcontract for fine crushing of mineralized material, agglomerating and stacking of mineralized material onto the leach pads.

Construction activities for the Pilot Plant - Phase I are progressing on time and on budget and include:

-- Improvements to onsite haul roads are underway and 90% complete-- Earthworks for the heap leach pad, crusher pad and onsite process building complete-- Earthworks for process ponds 90% complete-- Concrete works for onsite process building complete-- Placement of a homogeneous fine crushed material underliner on entirety of leach pad complete-- Installation of 60ml clay composite GLC white liner on leach pad complete-- Installation of black felt geomembrane on top of GLC liner complete-- Processing of 1/2 inch to 3/4 inch drain rock crush material for 18 inch layer on top of overliner underway 50% complete-- Construction and operation of sample preparation facility complete-- Placement on site of pre-constructed buildings for assay labs complete and modifications and installation of instruments and equipment underway-- Drilling and installation of four on-site water wells and pumps complete-- Installation of water pipeline from storage tanks to heap leach ponds complete



Initial placement of fine crushed agglomerated material (95% -1/4 inch) onto leach pads completed June 28, 2013, ahead of schedule. Initial treatment of solution through carbon columns for heap leaching anticipated by July 18, 2013. Total Phase I mineralized material of 90,000 mt expected to be placed onto the leach pads by September 15, 2013.
