Foran Announces Initial Drill Results from 2023 Winter Program at Tesla






Highlight Intercepts Include 4.04% Copper Equivalent over 17.4 Metres

 Tesla Strike Length Now Extended to 300m, Remains Open in All Directions

Assays Pending for Two Holes Intersecting Sulphides

Three Drill Rigs Now at Tesla

Foran Mining Corporation (TSX-V: FOM) (OTCQX: FMCXF) is pleased to announce initial drill results from its winter drill program at the new Tesla discovery, located approximately 300 metres north of Foran’s McIlvenna Bay Deposit in Saskatchewan.


Key Highlights:

  • Significant assay results from step out Hole TS-22-06A include:
    • 10.1m grading 3.1% Cu, 3.0% Zn, 32 g/t Ag and 0.25 g/t Au (4.62% CuEq)
    • 17.4m grading 2.1% Cu, 4.5% Zn, 29 g/t Ag, and 0.11 g/t Au (4.04% CuEq)
    • 17.1m grading 0.6% Cu, 13.1% Zn, 24 g/t Ag, and 0.04 g/t Au (5.69% CuEq)
  • Intercepts compare favourably to McIlvenna Bay’s Mineral Reserve of 25.7 Mt at 2.51% Copper Equivalent (“CuEq”).
  • Tesla discovery represents a significant mineralized zone, open in all directions, with opportunity to expand with further drilling.
  • TruScan results identify similarities between the Tesla Zone and McIlvenna Bay deposit, further exploration of McIlvenna Bay area continues to show potential to become one of the larger sulphide deposits across the Flin Flon Camp.
  • Exploration activity on Tesla is increasing with assays from two completed holes outstanding, and an additional 7-9 holes planned to be drilled this winter.


Dan Myerson, Foran’s Executive Chairman & CEO, commented “We are thrilled to announce the latest results from our Tesla exploration drilling program, which continue to demonstrate that our unique exploration methodology can unlock the potential for large critical metal systems across our landholdings. To date, six holes drilled into Tesla have intersected significant base and precious metal sulphides. In total, these holes have tested only 300m of strike and 300m of the dip extent of the mineralized horizon, which remains open in all directions. Given the geophysical conductor extends 900m in strike, there is a significant amount of potential to identify large-scale opportunities that can complement our existing McIlvenna Bay deposit as we strive to establish the next major critical metals infrastructure asset and district in one of the best mining jurisdictions in the world, Saskatchewan, Canada. As we ramp up with three drill rigs targeting the Tesla Zone, we are eager to announce more results in the near-future and routinely thereafter.”


Tesla Zone


The Tesla Zone lies adjacent to the McIlvenna Bay Deposit and was discovered during the 2022 summer program (see June 8, 2022 press release), while drill testing a ~900m (strike) by 300m (width) electro-magnetic conductor (Figure 1). Significant widths of copper and zinc-rich sulphide mineralization have now been intersected in six drill holes, over a 300m x 300m area, and three drills are currently focused on expanding the zone during the 2023 ice-based winter drill program.


Drill hole TS-22-06A was drilled downdip to the east, from surface to a depth of 1,314m, to provide additional information on the geometry of the zone. The hole intersected a 30m core length of vein and cleavage bound chalcopyrite and pyrrhotite associated with strong chlorite alteration, which is thought to be equivalent to the lower footwall zone at Tesla intersected in previous drill holes. This was followed by the intersection of the Main Zone comprising copper and zinc-rich massive, and semi-massive and stringer sulphides over a 50m core length associated with moderately to strongly chlorite +/- sericite and silica altered felsic volcanics. The drill hole also intersected a third interval with a 40m core length of significant zinc mineralization, which is currently interpreted to be a repeat of the Main Zone, extending the mineralization down dip for 200m below the previous intercepts.


TS-23-08 (assays pending) was drilled to the west from Hanson Lake and provides an orthogonal intersection into the Tesla zone near TS-22-06A, which indicates that the true width of the Main Zone is approximately 30m, confirming prior expectations. A cross section showing the relationship between these zones and previous drill holes is provided in Figure 3 and a table of detailed composites from TS-22-06A is provided in Table 1 below.


Geological Interpretation of Tesla Zone


Drill holes that have intersected the Tesla Zone to date have been analyzed using a TruScan Energy Dispersive X-ray Fluorescence (ED-XRF) system (see November 2022 news release). Preliminary data suggests that the Tesla mineralization is overlain by the same chemostratigraphic marker horizon as the McIlvenna Bay deposit (Figure 2). This indicates that the two zones are contemporaneous and may have once been linked together. The current 300m offset between the zones is postulated to be the result of either folding or post-mineral faulting. Additional drilling will be required to confirm the nature of the relationship between Tesla and McIlvenna Bay, but if this offset is a result of folding of the stratigraphy this may open significant new exploration space between the two deposits. The newly established stratigraphic link between McIlvenna Bay and the Tesla Zone, the 300m x 900m conductor plate, and recent drilling further increases the confidence in the potential size of the deposit. As the zone continues to grow, the McIlvenna Bay area continues to show potential to become one of the larger sulphide deposits in the Flin Flon Camp.


Existing ground EM surveys completed over McIlvenna Bay and Tesla had line orientations parallel to the trend of this potential connecting fold limb and may therefore have been blind to conductors in that orientation. Foran has recently purchased EM survey equipment and is planning to complete additional ground surveys this winter orthogonal to this trend to determine if additional conductors are present to assist in targeting follow up drilling.

2023 Exploration Program


The 2023 winter exploration program started on January 6th with two drills, one focused on the Tesla drilling and the second rig completing infill drilling on the McIlvenna Bay deposit. The McIlvenna Bay infill program has been designed to provide additional confidence in the resources in the near surface areas planned for the first few years of production, as well as to provide additional material for metallurgical work to fine tune the process flow sheet as part of ongoing advanced engineering studies.


Currently, the infill program at McIlvenna Bay is reaching completion and three drills are now located on the ice targeting expansion of the Tesla Zone, shown in Figure 5 below. It is anticipated that the Tesla ice drilling will continue until the end of March, subject to favourable ice conditions with 7,500m over 7-9 drill holes planned.


Planning is underway for continued regional exploration during the summer months on drill targets located both in proximity to McIlvenna Bay and on our Bigstone Project (located 25km to the west), along with geophysical surveys to define drill targets on our extensive land holdings to the south.


Quality Assurance and Quality Control


Drilling was completed using NQ size diamond drill core and core was logged by employees of the Company. During the logging process, mineralized intersections were marked for sampling and given unique sample numbers. Sampled intervals were sawn in half using a diamond blade saw. One half of the sawn core was placed in a plastic bag with the sample tag and sealed, while the second half was returned to the core box for storage on site. Sample assays are performed by the Saskatchewan Research Council (“SRC”) Geoanalytical Laboratory in Saskatoon, Saskatchewan. SRC is a Canadian accredited laboratory (ISO/IEC 17025:2017) and independent of Foran. Analysis for Ag, Cu, Pb and Zn is performed using ICP-OES after total multi-acid digestion. Au analysis is completed by fire assay with ICP-OES finish. A complete suite of QA/QC reference materials (standards, blanks and duplicates) are included in each batch of samples processed by the laboratory. The results of the assaying of the QA/QC material included in each batch are tracked to ensure the integrity of the assay data.
