Filo Mining Corp (TSX-V:FIL) (Nasdaq First North: FIL) is pleased to announce continued excellent results from the recently completed 2017/18 drill program at the Filo del Sol project in San Juan Province, Argentina and Region III, Chile. A total of 9,411 metres was drilled during the program, which was completed at the end of March, 2018. In total, 31 reverse circulation holes and 9 diamond drill (DD) holes were completed during the program. Assay results for 11 RC holes are presented here, and results from the remaining 9 DD holes will be released once the final assays have been received.
Highlights of Field Program:
A full table of the drill hole intersections, collar information and a plan map showing the locations of the drill holes are included within this release.
Highlights from this second batch of drill holes include:
Commenting on today’s results, Adam Lundin, CEO of Filo Mining stated, “The drill results from our 2017/18 field program continue to impress. The results released today, along with those we released on April 27 of this year, not only suggest that there is strong support to convert part of the inferred oxide mineral resource to the indicated category, they also support that testing for resource extension beyond the 2017 mineral resource limit at the Filo Del Sol Project is warranted. The results of the 2017/18 drilling will be incorporated into an updated mineral resource estimate to support the Pre-Feasibility Study (“PFS”) which is currently underway.”
Filo del Sol is a large high-sulphidation epithermal copper-gold-silver deposit. The upper portion of the deposit is oxidized and includes from top to bottom, a gold oxide zone, a copper-gold oxide zone and a silver-rich zone. The oxide portion of the deposit is underlain by copper-gold sulphide mineralization. The drill holes reported here tested all of the oxide zones. The northern section of the deposit which contains ~90% of the current resource is referred to as the Filo Zone; the southern section is referred to as the Tamberias Zone.
One of the main goals of the 2017/18 drill program was to convert a part of the inferred oxide mineral resource to the indicated category and most of the holes in this release were drilled for that purpose. The results suggest that we are well on our way to achieving this objective. The mineral resource remains open laterally and to depth, and several other holes were drilled adjacent to the inferred mineral resource in order to test for resource extensions. The holes in this release span a distance of 2.2 kilometres from VRC165 in the south to VRC164 in the north.
Nine of the holes announced today were drilled into the Filo zone of the deposit and are expected to either convert existing inferred material to indicated or add to the mineral resource.
The Filo gold oxide zone was intersected by the upper part of VRC164 (20m @ 0.95 g/t gold) in an area classified as inferred mineral resource.
All of the Filo holes intersected the copper-gold oxide zone, in areas that are either within the inferred mineral resource or adjacent to it, with grades that are generally consistent with those predicted by the mineral resource block model.
Three of the holes intersected the silver zone, including a broad zone of near-surface mineralization starting at 12 metres down the hole in VRC161 (80m @ 101.7 g/t silver). These silver zone intersections are all within the inferred mineral resource.
Two of the holes presented here were drilled into the Tamberias zone. VRC162 extends the gold oxide zone approximately 20 metres beyond the 2017 mineral resource limit and VRC165 intersected the copper-gold oxide zone in an area of inferred mineral resource.
The results of the 2017/18 drilling will be incorporated into an updated mineral resource estimate to support the Pre-Feasibility Study (“PFS”) which is currently underway. The PFS follows the completion of a Preliminary Economic Assessment (“PEA”) of the project, the results of which were released by the Company on November 28, 2017. The PEA incorporated open-pit mining and heap leach processing of only the oxide portions of the deposit. The results of the PEA demonstrate a robust project with strong economics, highlighted by an estimated after-tax NPV of US$ 705 million using a discount rate of 8% and an IRR of 23%, with an average estimated annual life of mine production of approximately 50,000 tonnes of copper, 115,000 ounces of gold, and over 5 million ounces of silver.
Diamond drill holes completed during the 2017/2018 program will contribute data for the mineral resource update and will also provide samples for metallurgical testwork forming an important part of the PFS. Metallurgical sample material was also collected from surface trenches during the field program. The PFS metallurgical testwork program is being carried out at SGS Minerals lab in Lakefield, Ontario and commenced in early April, 2018. Ongoing environmental and social programs continue in support of the PFS and to lay the groundwork for future environmental assessments and project permitting.

Mineralized zones within the Filo del Sol deposit are flat-lying, and drilled widths are interpreted to be greater than 95% of true widths.
The field program was carried out under the supervision of Bob Carmichael, B.A.Sc., P.Eng., who is the Qualified Person as defined by NI 43-101. Mr. Carmichael is Vice President, Exploration for the Company and has reviewed and approved the technical information contained in this news release.
The Quality Control/Quality Assurance program for the Filo del Sol Project is under the management of Diego Charchaflie MSc., P.Geo (BC), a Qualified Person pursuant to NI 43-101.
Samples were collected at the drill site by Company personnel with splitting carried out at the Company’s field camp near the drill sites. Individual samples represent final splits from 2 metre intervals down the hole. Samples were delivered to the ALS preparation laboratory in Copiapo, Chile where samples were crushed and split and a 500g split was pulverized to 85% passing 200 mesh. The prepared samples were sent to the ALS assay laboratory in Lima, Peru. ALS is an accredited laboratory which is independent of the Company. 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 and a sequential copper leach analysis was completed on each sample. 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 are Quality Control samples.
About Filo Mining Corp.
Filo Mining’s flagship project is its 100% controlled Filo del Sol Project located on the border between San Juan Province, Argentina and Region III, Chile. Filo del Sol is located between the prolific Maricunga and El Indio Gold Belts, two major mineralized trends that contain such deposits as Caspiche, La Coipa, Veladero, and El Indio. The region is mining-friendly and hosts a number of large scale mining operations. The project area is covered under the Mining Integration and Complementation Treaty between Chile and Argentina, which provides the framework for the development of cross border mining projects.
