NGEx Intersects 0.63% Copper Equivalent Over 340 Metres at Josemaria and Provides General Exploration Update for Argentina Projects
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Feb. 21, 2014) -NGEx Resources Inc. (TSX:NGQ) ("NGEx" or the "Company") is pleased to provide a general update on progress at its copper-gold projects in San Juan Province, Argentina. Highlights include:
- initial drilling results from the 2013/2014 program at the Josemaria copper-gold porphyry project located in San Juan Province, Argentina. A total of 7,302 metres in 14 holes were completed during the field season and drilling is now finished. Results from seven holes are released here, and assays for the remaining seven holes are pending.
- an update on the conceptual engineering studies underway to evaluate development options for Josemaria.
- an update on progress in the resource definition drilling at the Filo del Sol project also located in San Juan Province, Argentina.
JOSEMARIA DRILL RESULTS
The focus of this season's drill program was to define the high-grade supergene zone at the north end of the deposit and test for a possible extension of this zone to the northwest of previous drilling. Several larger step-out holes were also planned in order to test a broad area of leached cap extending to the north and northwest of the main deposit area.

Two of the holes reported here intersected the supergene zone; JMDH78 with 340 metres at 0.63% CuEq* (0.54% Cu and 0.11 g/t Au) and JMDH80 with 432.5 metres at 0.61% CuEq* (0.44% Cu and 0.22 g/t Au). Results of the initial holes from the season are presented below:
|Cu %||Au g/t||CuEq* %||Ag g/t|
|*CuEq - Copper Equivalent is calculated using US$3.00/lb copper, US$1,400/oz gold and US$23/oz Ag, with no provision for metallurgical recoveries. The formula used is CuEq% = Cu% + 0.6806*Au (g/t) + 0.011*Ag (g/t). Josemaria is a porphyry deposit, characterized by a large volume of relatively homogeneous mineralization and drilled lengths are interpreted to be representative of the true width of the mineralized zone.|
Drill hole JMDH78 was drilled within the Indicated resource block, and is expected to result in an increase in grade for this portion of the model.
Drill holes JMDH79, JMDH83 and JMDH85 were located to the northwest of the Josemaria resource. Distance from the edge of the Inferred resource for these holes was 300 metres, 90 metres and 200 metres respectively. These holes are significant because they extend the mineralized zone to the northwest and because they possibly reflect a separate mineralized porphyry center. Further drilling would be needed to confirm this idea.
Drill holes JMDH80, JMDH81 and JMDH82 were drilled along the edge of the Indicated portion of the resource model and will convert a portion of the Inferred resource to the Indicated category.

JOSEMARIA CONCEPTUAL STUDIES
Following receipt of an updated resource estimate for Josemaria in the second half of 2013 the Company contracted an independent third party engineering group to conduct a high level assessment of possible development options for the project. The scope of this ongoing option study includes an evaluation of potential mining methods and production rates, geotechnical drilling, ongoing metallurgical test work, including comminution studies, and development of high level processing flow sheets and mass balances. Engineering work has focused on the conceptual design of an open-pit mining operation of between 120,000 and 160,000 tonnes per day. Studies are ongoing and the above are only intended to provide a general idea of possible production levels. Work is ongoing and a variety of potential development scenarios continue to be considered. At a 0.30% copper equivalent* cut off grade, Josemaria has a current Indicated Resource of 789 million tonnes at 0.35% copper and 0.24 g/t gold and an additional Inferred Resource of 315 million tonnes at 0.28% copper and 0.17 g/t gold(i). Included within this resource is a shallow higher grade core (Indicated Resource at a 0.5% CuEq* cut off 355Mt @0.68% CuEq*, 0.44% Cu, 0.33% Cui) and opportunities for the early production of this material are being investigated. In addition to the exploration drilling described above two geotechnical holes were also completed. Metallurgical test work is ongoing at Josemaria. Baseline environmental programs, including review of areas for potential infrastructure are underway, with field work in progress during the current South American summer season.
FILO DEL SOL EXPLORATION UPDATE
Drilling continues at the Filo del Sol project located approximately 15km from Josemaria. Filo del Sol is a large copper-gold-silver high sulphidation system that overlies deeper porphyry copper copper-gold mineralization. This year's drill program is designed to provide sufficient data to allow for the estimation of an initial mineral resource for a stratabound, high-grade silver-copper zone which forms part of this large mineralized system. A secondary goal is to explore the area to the north of the current drilling, where the geological interpretation suggests the occurrence of a feeder zone to the stratabound mineralization. This feeder zone could contain significant gold and copper mineralization, as indicated by the two most northerly holes drilled to date which contain some of the best gold and copper intersections on the property (VRC28: 136m @ 0.71 g/t Au, 0.46% Cu (incl. 24m @ 2.14 g/t Au, 0.94% Cu) and VRC35: 126m @ 0.69 g/t Au, 0.50% Cu (incl. 10m @ 3.66 g/t Au, 0.28% Cu) - both previously released). This mineralization remains completely open to the north, east and west, and both holes ended in good grades.
A total of 5,875 metres of drilling in 18 holes had been completed as of February 9th, 2014, with assay results pending for all holes. Approximately 7,000 metres of drilling is planned. Drilling is expected to continue until early March, and assay results will be released once they have been received, checked, and compiled.

The drill core was logged and sawed at the Company's core facility in San Juan, Argentina. Half cores were sampled in their entirety in two meter intervals or intervals corresponding to geologic breaks determined by Company personnel. Samples were shipped to Acme Labs in Mendoza, Argentina for preparation and pulps were forwarded to the ACME lab in Santiago, Chile. Samples were crushed, split and 500g was pulverized to 85% passing 200 mesh. Gold analyses were by fire assay fusion with AAS finish on a 30g sample. Copper was analyzed by AAS using a 4 acid digestion and samples were also analyzed for a suite of 36 elements with ICP-ES. Copper and gold standards as well as blanks and duplicates (field, preparation and analysis) were randomly inserted into the sampling sequence for Quality Control. On average, 9% of the submitted samples correspond to Quality Control samples.
