Filo Mining Expands Bonita Over 200m East with 1,365m at 0.42% CuEq; Reports 1,363m at 0.77% CuEq in Aurora
VANCOUVER, BC, May 29, 2023 /CNW/ - Filo Mining Corp. (TSX: FIL) (Nasdaq First North Growth Market: FIL) (OTCQX: FLMMF) (“Filo Mining”, or the “Company”) is pleased to announce assay results from holes testing four different zones at the Filo del Sol Project in San Juan, Argentina. Highlights and detailed results are shown below along with accompanying figures:
- Drillhole FSDH075 in the Bonita Zone intersected 1,365m at 0.42% CuEq from 197.1m, including:
- 291.7m at 0.66% CuEq from 910.4m
- Collared 222m east of the Bonita discovery hole, FSDH060.
- Drillhole FSDH076 in the Aurora Zone intersected 1,363m at 0.77% CuEq from 180m, including:
- 354.9m at 1.01% CuEq from 496m
- Collared 2.2km southwest of FSDH075.
- A magnetotelluric (MT) geophysical survey was recently completed and supports the interpretation of a geological connection between Aurora and Bonita. Modelling of the survey data shows a zone of elevated conductivity trending north-northeast along the length of the Filo del Sol and Aurora Zones and continuing strongly as far as holes FSDH060 and FSDH075 at Bonita. Combined with the geology seen in these two holes, this provides strong evidence that the system is continuous along at least 3.5km and that Bonita is the northern part of the system, rather than a separate zone.
Commenting on the results, Jamie Beck, President, and CEO stated, “Hole 75 has successfully extended the Bonita Zone to the east and at depth, leaving it open to expansion in all directions. Our recently completed MT geophysical survey strongly indicates continuity between Aurora and Bonita across the undrilled gap of 1.3km between FSDH083 in the south and FSDH075 in the north. We are currently setting drills up to test this gap, which offers the potential to almost double the size of the deposit if the grade is there. We also have hole FSDH085 underway, 750m to the east of FSDH075, targeted on geophysics and surface geology which, if successful, will continue to expand Bonita. The initial holes at the Gemelos and Flamenco targets were encouraging, and we will follow up on these areas once the winter season concludes.”

Mineralized zones within the mineralized zones at Filo del Sol are bulk porphyry-style zones and drilled widths are interpreted to be very close to true widths.
FSDH075 was collared 222m east of hole FSDH060 on section 11000N and drilled towards the west parallel to it.
The geology logged in these two holes has many similarities to that at Aurora, suggesting that Bonita is part of the same system, rather than a discrete porphyry centre. The host rocks consist of fragmental and coherent rhyolite intruded by granite at depth, as at Aurora. These units are cut by a body of magmatic-hydrothermal breccia intruded by porphyry dykes, and a phreatic breccia with vuggy residual quartz clasts near the top of FSDH075. Alteration includes quartz-clay in the rhyolite and sericitic alteration with high-sulphidation mineralization in the granite. Potassic alteration is encountered towards the bottom of FSDH075 near the porphyry dykes.
The interval starting at 197.1m is associated with a phreatic breccia with quartz-alunite alteration, similar to the upper levels of high-grade sections of the Aurora Zone, and drilling deeper on this structure is a high priority. The interval starting at 910.4m is adjacent to and within the magmatic-hydrothermal breccia similar to the main mineralized unit at Aurora. Additional drill testing of this breccia to determine its size and tenor is also a high priority.
FSDH076 was collared from the same platform as FSDH070A on Section 9000N and drilled to the west at -70 degrees. It is separated by 90m from the end of FSDH070A, and continued an additional 204.5m deeper. Geology correlated very well with holes FSDH070A, FSDH046 and FSDH032A - all of which are on the same section. The magmatic-hydrothermal breccia extended from 386m to 811m where the hole transitioned into well-mineralized porphyry cut by a dense stockwork of A-type veins accompanied by a sharp change from high-sulphidation to porphyry-style mineralization.
The lower (western) contact of the porphyry was intersected at 1,198m and the hole passed back into the breccia, continuing in porphyry mineralization characterized by chalcopyrite +/- bornite rather than the high-sulphidation assemblage of enargite + chalcocite +/- covellite + bornite. The hole continued in mineralized breccia to its end at 1,543m.
FSDH079 is the first hole drilled into the Gemelos target and was collared 2.6km northeast of FSDH075. Although copper and gold grades were low throughout the hole, the volcano-sedimentary sequence intersected is weakly to strongly altered and pyritized, defining the classic pattern of a high-sulphidation epithermal system. The advanced argillic alteration with associated high-sulphidation mineralization is interpreted to be linked to an associated porphyry system elsewhere in the Gemelos alteration zone. This zone is roughly equivalent in size to the Filo del Sol alteration zone and remains a high-potential target which warrants additional work.
FSDH081 is the second hole drilled into the Flamenco target. For reference, this hole is located 8.2km southwest of FSDH079 highlighting the size of the exploration area at Filo. It was collared 723m southwest of FSDH077, the first Flamenco hole which was reported in the Company’s news release dated March 16, 2023. This hole expanded the area of moderate grade mineralization intersected in hole FSDH077 and continued to support Flamenco as a high-quality exploration target which requires significant additional work.
Outlook
Drilling is ongoing with 9 rigs active on the project and, with winter imminent, will focus on the Aurora-Bonita gap and Aurora infill drilling.
Holes that have been completed with assays pending include:
- FSDH072 – Aurora (1,787m)
- FSDH080 – Aurora (1,348m)
- FSDH082A – Gemelos (839.5m)
- FSDH083 – Aurora North Extension (1,550m)
- FSDH085 – Bonita East (1,199m)
Assay results for completed holes will be released as they are received, analyzed, and confirmed by the Company. Four rigs are currently moving onto new holes, including three in the Aurora-Bonita gap, and the ninth rig is completing the last of a series of geotechnical holes to examine a potential future underground exploration adit.

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. RC 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 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.
1Copper Equivalent (CuEq) 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).
