VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec. 2, 2014) -NGEx Resources Inc. (TSX:NGQ)(NASDAQ OMX:NGQ) ("NGEx" or the "Company") is pleased to announce the initial mineral resource estimate for the Filo del Sol silver-copper-gold deposit. The deposit is located on the border between Chile and Argentina and is 100% controlled by NGEx. These results confirm a large resource with a significant oxide component and distinct high grade silver and copper zones. All mineral zones remain open to expansion.

Filo del Sol is a high-sulphidation epithermal copper-gold-silver deposit. Overlapping mineralizing events combined with weathering effects, including supergene enrichment, have created several different styles of mineralization at Filo, including structurally-controlled gold, manto-style high-grade silver (+/- copper) and high-grade supergene enriched copper within a broader envelope of disseminated sulphide copper and gold mineralization. Filo del Sol is part of an emerging cluster of significant copper-gold deposits which includes the Company's nearby Los Helados and Josemaria deposits.

The resource estimate presented in Table 1 below represents the total Inferred Resource, divided between oxide and sulphide mineralization and based on a copper equivalent cutoff grade. Two higher-grade subsets of this resource are also broken out, one representing a discrete high-grade silver zone (the "Silver Zone") shown in Table 2, and one representing a higher-grade copper zone (the "Copper Zone") shown in Table 3. The Silver Zone and the Copper Zone are separate zones that are included within the total Inferred Resource envelope.

The total Inferred Resource for the Filo del Sol deposit, at a 0.30% CuEq1 cutoff grade is:

  • 280.5 million tonnes at a grade of 0.38% copper, 0.32 g/t gold, 9.7 g/t silver and 54 ppm molybdenum for a copper equivalent grade of 0.66% (2.3 billion pounds of copper, 2.9 million ounces of gold, and 87.8 million ounces of silver).

The Mineral Resource estimate as of the effective date of November 25, 2014 is shown in the tables below:

TOTAL 280.5 0.38 0.32 9.7 54 0.66 2.3 2.9 87.8
1 - Copper equivalent assumes metallurgical recoveries of 84% for copper, 70% for gold, 77% for silver and 60% for molybdenum based on similar deposits, as no metallurgical testwork has been done on Filo del Sol mineralization, and metal prices of US$3/lb copper, US$1300/oz gold, US$23/oz silver and US$12/lb molybdenum. The CuEq formula is: CuEq=Cu+Agx0.0102+Aux0.5266+Mox0.0003;
2 - The Qualified Person for the resource estimate is James N. Gray, P.Geo., of Advantage Geoservices Ltd.;
3 - All figures are rounded to reflect the relative accuracy of the estimate;
4 - Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability;
5 - The resource was constrained by a Whittle® pit shell using the following parameters: Cu $3/lb, Ag $23/oz, Au $1300/oz, Mo $12/lb, slope of 42°, mining cost of $2.2/t and process cost of $7.4/t.

The total resource shown above in Table 1 includes a subset of high-grade silver mineralization. The Silver Zone is tabulated below at three different silver cutoff grades.

The total resource shown above in Table 1, also includes a subset of higher-grade copper mineralization which is in addition to the high-grade silver zone. The Copper Zone is tabulated below at two different copper cutoff grades.

Commenting on today's news release, Wojtek Wodzicki, President and CEO of NGEx stated, "We are very pleased with these results. The initial Resource estimate is an important milestone and demonstrates the potential of Filo del Sol to host high-grade silver mineralization along with significant copper, gold, and molybdenum. Filo del Sol is the largest alteration zone in this part of the Andes and drilling to date has tested only a small portion of it. We are optimistic that further drilling can add significantly to the current resource."


The resource estimate was completed by James N. Gray, P.Geo., of Advantage Geoservices Ltd., an Independent Qualified Person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects (NI 43-101) in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Mineral Reserves, adopted by CIM Council, as amended. Estimation methods are summarized below. Further details of the estimation methods and procedures will be available in a NI 43-101 Technical Report which will be filed on SEDAR (www.sedar.com), within 45 days from the date of this release.

The resource estimate is controlled by a geologic model based on the interpretation of drilling on 100 metre spaced cross-sections. Ninety holes (16 core and 74 RC) have been utilized in the resource estimation. Copper, silver, gold, and molybdenum assays were composited to a constant length of two metres. Outliers to the composite distributions were controlled by high-grade capping. Grades for the four elements were estimated by ordinary kriging using Gemcom® software, into 15 x 15 x 10m blocks. Average rock densities were applied based on the geologic model. A total of 878 density measurements have been made on core samples. Bulk density for the deposit averages 2.31 tonnes/m3.

Reasonable prospects of economic extraction were established by the optimization of a Whittle® pit shell using the following parameters: Cu $3/lb, Ag $23/oz, Au $1300/oz, Mo $12/lb, slope of 42°, mining cost of $2.2/t and process cost of $7.4/t. Blocks were assigned as Inferred Mineral Resource where they are: within 50m of a drillhole and/or have sample data in at least three octants of a 150m spherical search and fall within the optimized pit shell. At a copper equivalent cutoff grade of 0.3%, the optimized pit shell results in a strip ratio of 1.8:1.


The planned 2014-2015 work program for the Filo del Sol project includes up to 8,000 metres of drilling which will be focused on expanding this initial resource laterally in all directions. A portion of the step out drilling program will target a potential feeder zone for the mineralization which has been highlighted by geophysical surveys. The program will also include a limited number of infill holes in key locations which will help to define the distribution of metal grades within the deposit, including arsenic which is present at elevated levels consistent with other high sulphidation epithermal deposits. Drilling is expected to start during December.

An induced polarization (IP) geophysical survey is currently underway, and will be used to guide the drilling outside of the resource area. IP has proven to be a very effective method to map out the mineralization and the current data set suggests there is good potential to expand the high-grade Copper and Silver zone mineralization, particularly to the west.
