Filo Mining Reports 61% Increase in Resource Tonnes at Filo del Sol Project

/EINPresswire.com/ -- VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug 21, 2017) - Filo Mining Corp. (TSX VENTURE:FIL)(OMX:FIL) ("Filo Mining" or the "Company") is pleased to announce a significant increase to the Mineral Resource estimate for its 100% controlled Filo del Sol copper-gold-silver deposit located along the Chile-Argentina border.

Commenting on today's news release, Wojtek Wodzicki, President and CEO of Filo Mining remarked, "Today's results confirm Filo del Sol as one of the best growth projects in South America. With less than 9,000 metres of new drilling we were able increase the resource by 61% and more importantly, define distinct gold oxide, copper-gold oxide, and silver zones that are amenable to heap leach processing. The tonnes and grades in the copper-gold oxide zone by itself are comparable to some of the larger copper leach operations in Northern Chile with the added benefit of significant precious metal resources in the gold and silver zones. The exploration upside at Filo is excellent and we are confident that this resource still has room to grow. These results are an important step toward our goal of building Filo Mining into a significant new gold, copper, and silver producer."

Highlights (see Table 1 for resource details):

  • Significant Increase in overall resource tonnes and contained metals.
    • Resource tonnes increased by 61% to 372.9 million tonnes Indicated plus 238.9 million tonnes Inferred;
    • Total contained gold increased by 62% to 4.0 million ounces Indicated plus 2.5 million ounces Inferred
    • Total contained copper increased by 28% to 2.8 billion pounds Indicated plus 1.4 billion pounds Inferred
    • Total contained silver increased by 13% to 110 million ounces Indicated plus 60 million ounces Inferred
  • Resource has now been divided into four zones based on metallurgical characteristics. Metallurgical testwork completed to date indicates that the oxide zones are amenable to heap leach processing and that the silver zone could either be leached or processed by flotation to produce a silver-rich concentrate. The conceptual engineering studies now underway focus on the upper three zones. From top to bottom these are:
    • A gold oxide zone (AuOx) containing 710,000 ounces of gold Indicated plus 368,000 ounces of gold Inferred.
    • A copper-gold oxide (CuAuOx) zone containing 1.6 billion pounds of copper and 1.6 million ounces of gold Indicated plus 0.6 billion pounds of copper and 0.9 million ounces of gold Inferred.
    • A silver zone (Ag) containing 82 million ounces of silver Indicated plus 43 million ounces of silver Inferred.
    • These three zones are underlain by a copper-gold sulphide zone (sulphide), which has not been tested metallurgically yet but based on the mineralogical characteristics is likely to be able to be processed by flotation to produce a concentrate.
    • It is important to note that there are significant zones of higher grade material within the broader resource envelope shown in Table 1 - these can be seen at the higher cut-off grades shown in Tables 2-5.
  • Favourable topography for open pit mining methods.
  • Excellent conversion of Inferred tonnes to the Indicated category. 61% of the new resource is now Indicated. The conversion rate of Inferred to Indicated was 98%.
  • Exploration Upside. The resource remains open for expansion in several directions and at depth. To date only 3 kilometres of the approximately 7 kilometre long strike length of the Filo alteration zone has been drill tested. All holes drilled into the deposit, including the deepest holes at 500 metres long, end in mineralization and the potential for porphyry copper-gold mineralization at depth is considered excellent.

The resource estimate presented in Table 1 represents the total Indicated and Inferred Resource, divided between a gold oxide zone (AuOx), a copper-gold oxide zone (CuAuOx), a silver zone (Ag) and a primary sulphide mineralization zone (sulphide). Each of these zones was reported at a different cutoff grade, based on expectations of the most important metal or metals in each zone. Base case cutoff grades are shown in Table 1 and each zone is reported at a range of cutoff grades in Tables 2-5 below. These four discreet mineralized zones have been aggregated to derive the total mineral resource. The different zones reflect distinct styles of mineralization based on mineralogy, grade distribution and deposit geology and have different metallurgical characteristics based on preliminary testwork completed to date.

This new resource estimate updates and replaces the resource estimate released on November 23, 2015 and is based on a total of 36,200 metres of primarily reverse circulation drilling including an additional 7,500 metres of reverse circulation drilling in 37 new holes from the drill program completed in March 2017. Most of the increase in the resource estimate comes from the Filo South zone which is included in the resource for the first time. Filo South is contiguous with the main Filo deposit. In addition, the oxide gold mineralization at the Filo deposit was not broken out in the previous resource estimate, but drilling this past season has greatly expanded both the size and grade of this area to the point where it is now significant enough to report on its own.

This resource update forms the basis for internal conceptual studies which are now underway to evaluate potential project development options. A decision on whether to proceed towards a Preliminary Economic Assessment ("PEA") is expected during the third quarter of 2017.

A technical report prepared according to the guidelines of NI 43-101 and summarizing this resource estimate will be available under the Company's profile on SEDAR within 45 days. The Mineral Resource estimate as of the effective date of July 1, 2017 is shown in the tables below:

ESTIMATION METHODS

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 three-dimensional interpretation of drill results. An additional 37 holes have been included in this resource update compared to the 2015 Inferred Mineral Resource. In total, 144 holes (18 core and 126 RC) have been utilized in the resource estimation. Copper, silver, and gold assays were composited to a constant length of two metres. Outliers to the composite distributions were controlled by high-grade capping. Grades for the three 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.

Contiguous blocks were assigned as Inferred Mineral Resource where they are nominally: within 50m of a drillhole and/or have sample data in at least three octants of a 150m spherical search. Indicated blocks are greater than 25m inside the classified volume and estimated by at least three holes, and within 65m of the closest hole or have samples in at least five octants of a 150m spherical search.

Reasonable prospects of eventual economic extraction were established by the optimization of a Whittle® pit shell using the following parameters: Cu $3/lb, Ag $20/oz, Au $1300/oz, average recoveries of: 75% Cu, 68% Au and 82% Ag, slope of 45°, mining cost of $2.50/t and an average process cost (including G&A) of $13.26/t. All material included in the Mineral Resource Estimate is within the optimized pit shell. Reported at the cutoff grades by zone as presented in Table 1, the optimized pit shell results in a strip ratio of 1:1.

QUALITY ASSURANCE/QUALITY CONTROL

Samples were collected at the drill site by Company personnel with initial splitting carried out at a facility near the drill sites and final splitting completed at the Company's core processing facilities located in San Juan, Argentina or Copiapo, Chile. Individual samples represent final splits from 2 metre intervals down the hole. Samples were analysed the ALS laboratory in Mendoza, Argentina or ACME Labs 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 and silver were analysed by atomic absorption following a 4 acid digestion. 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.
