Filo Mining drills 130 metres of 1.25% copper and 40 metres of 1.50 g/t gold at Filo del Sol






Filo Mining Corp (TSX-V:FIL) (Nasdaq First North: FIL) is pleased to announce the final assay 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 holes were completed.  Assay results for the 9 diamond drill holes are presented here.  Results of the reverse circulation holes are contained in previous news releases dated April 27 and May 16, 2018. 



Highlights of Field Program:


  • Infill drilling is expected to convert a portion of the inferred oxide mineral resource to indicated
  • Step out drilling has extended mineralization beyond the current resource limits and it still remains open for expansion
  • Over 4.5 tonnes of material was collected for metallurgical, geotechnical and environmental testing in support of the Pre-Feasibility Study (“PFS”) currently underway
  • Geotechnical drilling has been completed



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:


• FSDH016: 4m @ 0.22% Cu, 0.19 g/t Au, 1,001.0 g/t Ag
• FSDH017A: 88m @ 0.95% Cu, 0.19 g/t Au, 43.4 g/t Ag
• FSDH020:  40m @ 0.02% Cu, 1.50 g/t Au, 3.0 g/t Ag
• FSDH021:  141m @ 0.98% Cu, 0.30 g/t Au, 56.7 g/t Ag
• FSDH022:  130m @ 1.25% Cu, 0.28 g/t Au, 1.5 g/t A
  • Including  26m @ 4.98% Cu, 0.30 g/t Au, 0.7 g/t Ag
• FSDH023: 72m @ 1.02% Cu, 0.26 g/t Au, 108.5 g/t Ag
  • Including 12m @ 1.24% Cu, 0.36 g/t Au, 628.8 g/t Ag



Commenting on today’s results, Adam Lundin, CEO of Filo Mining stated, “”We are very pleased with the final drill results revealed from our 2017/18 field program at Filo del Sol. The results released today along with the first two sets of program results released in April and May of this year, respectively validate the Company’s confidence in moving forward to complete an updated mineral resource estimate, and its in-progress efforts to release a Pre-Feasibility Study in early 2019.”



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. 



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.  Diamond drilling was used in order to collect coarse sample material for column leach metallurgical testwork, as well as for resource infill.  The mineral resource remains open laterally and to depth.  The holes in this release span a distance of 730 metres from FSDH021 in the south to FSDH022 in the north.



The Filo gold oxide zone was intersected by the upper part of FSDH017A (58m @ 1.09 g/t gold) and FSDH020 (122m @ 0.67 g/t Au) 140 metres to the north. 



Drill holes FSDH021 and FSDH023 intersected the southern high-grade copper zone within the indicated mineral resource, confirming the size and tenor of this zone and providing material for metallurgical testwork.  Hole FSDH017A intersected the northern high-grade copper zone, 400 metres northwest of FSDH021 and hole FSDH022 intersected a shallower high-grade zone 400 metres north of FSDH017A.  The intersection in FSDH022 included a very high-grade section of 8 metres that returned 12.8% Cu.  This zone remains open to the north.  Hole FSDH019 was abandoned just above the copper zone.       



Four of the holes intersected the silver zone, including another broad zone of near-surface mineralization starting at 30 metres down the hole in FSDH016 (62m @ 103.1 g/t silver).  The silver zone intersections included some very high silver values (4m @ 1,001.0 g/t Ag in FSDH016; 6m @ 798.7 g/t Ag in FSDH021 and 4m @ 1,498.0 g/t Ag in FSDH023) as is typical within this zone.  The silver zone intersections in holes FSDH021 and 023 are within the indicated mineral resource while those in FSDH016 and 017A are within the inferred mineral resource.



The results of the 2017/18 drilling will be incorporated into an updated mineral resource estimate to support the PFS which is currently underway.  The PFS follows the completion of a Preliminary Economic Assessment 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.
