Filo Mining Corp. (TSX: FIL) (Nasdaq First North Growth Market: FIL) (OTCQX: FLMMF) is pleased to announce assay results from holes FSDH055C and FSDH059 from the ongoing drill program at the Filo del Sol Project.  Hole FSDH055C is the best hole drilled on the project to date, measured by copper-equivalent multiplied by intercept length, and ended in strong mineralization at almost 1,500m depth.

FSDH055C returned 1,337.5m at 1.33% CuEq from 150m, including:

• • 126.0m at 5.02% CuEq from 728m in Breccia 41, including
  • 24.0m at 13.30% CuEq from 728m within the same zone
  • The latter intersection included an 8.6m section at 20.25% CuEq

• The hole was stopped at a depth of 1,487.5m due to the capacity of the drill, and ended in strong porphyry-style mineralization with the last 21.5m of the hole at 0.93% CuEq (0.62% Cu, 0.41 g/t Au, 0.9 g/t Ag).

Commenting on the results, Jamie Beck, President and CEO stated, “From a grade-thickness perspective, hole 55C is the best hole ever drilled at Filo del Sol.  It represents one of the thickest, highest-grade intervals drilled through the Aurora Zone, and confirms the continuity of the bonanza-grade Breccia 41 mineralization between holes 41 and 54 to the south, and hole 57 to the north. At almost 1.5km deep, and still strongly mineralized, hole 55C is a great reminder of not only the size and scale of the system, but also how much more there is to discover at Filo.”

FSDH055C was collared on the same platform as FSDH041 and drilled to the west at an angle of -70^o. The hole deviated to the north, such that at the depth of the Breccia 41 intersection it is 40m northeast of FSDH041.  At 1,380m down hole, it is 80m northwest of the end of hole FSDH054.

The hole drilled through strongly altered rhyolite volcaniclastics and microdioritic dykes up to 360m, where the first porphyry veins appear. Intense advanced argillic alteration, with quartz-alunite, residual (vuggy) quartz and silicification are accompanied by disseminated and vein-controlled high sulphidation assemblages (covellite-chalcocite-enargite/tennantite) down to a remarkably sharp transition to a thick sequence of early magmatic-hydrothermal breccias and porphyry bodies at 1,000m. From 1,000m to the end of the hole copper mineralogy changes to chalcopyrite which appears along with potassic alteration.

The high-grade Breccia 41 is intersected between 728m and 854m, where it contains some of the highest-grade mineralization drilled on the project to date. The best 2m sample interval returned 32.58% CuEq (13.85% Cu, 6.63 g/t Au, 1580.0 g/t Ag). Other than hole FSDH057 (134m to the north), which also intersected Breccia 41, there are no holes up-dip, down-dip, or to the north, west or east of the intersection in FSDH055C.

FSDH059 was collared on section 9300N, 100m north of FSDH041, and drilled at an angle of -70^o towards the west to a final depth of 311.5m where it was terminated due to drilling difficulties. The hole ended in mineralization just as it was entering the Silver Zone, manifested by the same rock type as seen in the Silver Zone intersection in hole FSDH055A, 100m to the south. A follow-up hole to test this area will be started shortly.

Outlook

Drilling is ongoing with 7 diamond drill rigs, in addition to a reverse circulation (RC) rig, and eight holes are currently underway. Holes are designed to explore the area around the high-grade intersections in FSDH041, FSDH054, FSDH057 and now FSDH055C, along with some moderate step-outs to test continuity of the Aurora Zone, and larger step-out holes to continue to try to find the edges of the mineralized zone.

One hole, FSDH060, located 2km northeast of FSDH041, has been completed to a final depth of 1,070m and assays are pending. Results for these holes will be released once the holes are completed, and results are analyzed and confirmed by the Company.

About Filo del Sol

Filo del Sol is a high-sulphidation epithermal copper-gold-silver deposit associated with one or more large porphyry copper-gold systems. Overlapping mineralizing events combined with weathering effects, including supergene enrichment, have created several different styles of mineralization, including structurally controlled and breccia-hosted gold, manto-style high-grade silver (+/- copper) and high-grade supergene enriched copper within a broader envelope of disseminated, stockwork and breccia-hosted sulphide copper and gold mineralization. This complex geological history has created a heterogeneous orebody which is characterized by zones of very high-grade copper +/- gold +/- silver mineralization within a large envelope of more homogeneous, lower-grade mineralization.

Qualified Persons and Technical Notes

The scientific and technical disclosure for the Filo del Sol Project included in this news release have been reviewed and approved by 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. Samples were cut at Filo Mining’s operations base near the town of Guañizuil, Argentina by Company personnel. Diamond drill core was sampled in 2 metre intervals (except where shortened by geological contacts) using a rock saw for sulphide mineralization. Oxide mineralization was cut with a core splitter in order to prevent dissolution of water-soluble copper minerals during the wet sawing process.  Core diameter is a mix of PQ, HQ and NQ depending on the depth of the drill hole.  Samples were bagged and tagged and packaged for shipment by truck to the ALS preparation laboratory in Mendoza, Argentina where they were crushed and a 500g split was pulverized to 85% passing 200 mesh. The prepared samples were sent to the ALS assay laboratories in either Lima, Peru or Santiago, Chile for copper, gold and silver assays, and multi-element ICP and sequential copper analyses.  ALS is an accredited laboratory which is independent of the Company.  Gold assays were by fire assay fusion with AAS finish on a 30g sample. Copper and silver were assayed 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 with copper greater than 500ppm (0.05%). 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. No data quality problems were indicated by the QA/QC program.

Mineralized zones within the Filo del Sol deposit are typically flat-lying, or bulk porphyry-style zones and drilled widths are interpreted to be very close to true widths.  Additional drilling is required to estimate the true width of the bonanza grade mineralization within Breccia 41.

¹Copper Equivalent (for drill intersections is calculated based on US$ 3.00/lb Cu, US$ 1,500/oz Au and US$ 18/oz Ag, with 80% metallurgical recoveries assumed for all metals.  The formula is:  CuEq % = Cu % + (0.7292 * Au g/t) + (0.0088 * Ag g/t).
