Preliminary Economic Assessment Underway 3 Phase Mine Development Model Planned
Northern Vertex Mining Corp. (the "Company") (TSXV: NEE) is pleased to provide a corporate update on exploration and project development plans for the Moss Gold-Silver Project located in Mojave County, Arizona, USA with highlights as follows:
- NI 43-101 compliant mineral resource 956,800 AuEq (oz) measured and indicated, 266,340 AuEq (oz) inferred (see resource estimate summary below)
- Low strip ratio in initial mining areas possible
- Amenable to low cost, heap leach, open pit mining
- Major stockwork vein system outcropping at surface for 5,000 feet

- Additional resource definition drill program currently underway to increase resources adjacent to proposed pits and for data use in mine design and planning - targeting an additional 250,000 AuEq (oz)
- 3 Phase model approach now in place for mine development, to minimize initial Capex and to ensure technical and economic objectives are met for subsequent Phases prior to proceeding
- Application for Aquifer Protection Permit for 90,000 tonne Pilot Phase I quarry/leach pad will be submitted to Arizona Department of Environmental Quality (DEQ) by month end
- Phase II production target, 5,000 tpd
- Phase III production target 10,000 tpd
- Preliminary Economic Assessment (PEA) underway and expected early in new year
Location and Property Description:
The Moss Gold-Silver Property is located in the northern part of the Oatman Mining District, Mojave County, Arizona, USA. The Moss deposit is a mineralized quartz-calcite vein and stockwork up to 45 feet wide; it strikes approximately N70°W and dips 65-75° SW; the outcropping surface trace has a strike length of 5000 feet. The Moss property hosts low sulphidation epithermal vein-type gold mineralization.
The Moss property has easy access to supplies, accommodations, workforce, infrastructure and power. The nearest town is Oatman, Arizona (6.2 miles); the nearest cities are Bullhead City, Arizona and Laughlin, Nevada. Las Vegas, the nearest major city, is located only 80 miles northwest of the Moss Property and is a short 2 hour drive.
Exploration Program Update:
Exploration will focus on two elements:
- Mine exploration program
- Surrounding property exploration program
The mine exploration program is the Company's current exploration priority. A comprehensive resource definition drilling program is currently underway in the starter open pit mine area with a focus on two central hills with significant vein outcropping at surface. Drill results will be utilized in testing the extensions of the known mineralization, in mine modeling, to streamline the initial mine design of the starter pit and to add additional resources to the planned Phase 2 Mine Plan. Drilling to expand the resource is expected to continue into 2014 also targeting increasing the resources available for the Phase 3 Mine Plan. The internal target is to add 250,000 ounces of gold equivalent adjacent to the currently planned pit areas thereby extending the mine life by three years or enabling expansion of the current design capacity from 10,000 tpd to 13,300 tpd.
The surrounding property exploration program is expected to see a drilling program commence in early 2014 and will be ongoing throughout the first few years of mine operation. This will be a property wide program looking to add a million ounces to the Company's resource statement. The target for the Moss property as a whole will be 2 million ounces of gold equivalent.
Moss Project Current Resource:
On September 10, 2012, an updated NI 43-101 compliant mineral resource estimation was announced for the Moss Property with results as follows:
Scott E. Wilson Consulting Inc. Summarized Updated Resource Estimate: Table 1 Reported at 0.3 gpt Au Cutoff
Resource Category (oz) Au (oz) Ag (oz) Tonnes Grade
AuEq Au Ag
(gpt) (gpt) (gpt)
Measured 427,820 348,000 3,991,000 12,465,000 1.07 0.87 9.96
Indicated 528,980 432,000 4,849,000 18,414,000 0.89 0.73 8.19
M+I 956,800 780,000 8,840,000 30,879,000 0.96 0.79 8.90

* 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 estimate.;* 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 28,871 m of drilling in 330 exploration drill holes and 590 meters of channel sampling from surface and underground trenches and cross-cuts. There were a total of 5,872 drill composite samples and 269 rock channel samples used in the estimation of gold and silver. SEWC used Inverse Power Distance (ID3) as the preferred estimation technique for the Moss Project.
3 Phase Mine Development Plan:
The 3 Phase mine development plan is designed to sequentially progress the project from conceptual design and laboratory test work to pilot plant testing in the field and, if this is successful, to secure financing and permitting approval for building a 5000 tonnes per day mine initially and, if this is successful, then move to 10,000 tonnes per day ultimately. The mine, should it proceed to production, will be a classic heap leach operation.
The business plan has been specifically designed to take advantage of the natural attributes of the Moss deposit while minimizing the capital required to get into production and minimizing the lead time in doing so, thereby reducing project development risk and capital risk.
Phase I is a pilot plant operation with operations expected to commence in Q2 2013. Phase II operations are expected to commence in Q1 2014 at a rate of 5,000 tpd. Phase III operations are expected to commence in Q4 2017 at a rate of 10,000 tpd. These numbers are being used as the basis of the Preliminary Economic Assessment now underway and are subject to review.
Please find below the link for the proposed development schedule.
The Company's objective is to support the local communities and business wherever possible for both employment and mine supplies and services. Preliminary estimates of direct and indirect employment for each mining Phase are listed below and utilize a multiplier effect of 3:1.
Development Phase: Direct Employment Indirect Employment Total Employment
Phase I 40 120 160
Phase II 100 300 400
Phase III 150 450 600
Engineering and Design:
The immediate goal of the Company's engineering studies is the completion of a Preliminary Economic Assessment (PEA). The PEA will incorporate mine, processing and heap leach designs, and will include estimates of capital and operating costs and pre-tax cash flows for Phases I and II. A scoping level analysis will be subsequently prepared for Phase III.
The Preliminary Economic Assessment is expected to be completed early in the new year.
The project team will be led by Project Manager Mr. Joe Bardswich. The following consultants have been engaged to carry out the Preliminary Economic Assessment and initial mine design work:
