New Copper-Zinc Lens Identified in Tesla Footwall
Foran Mining Corporation (TSX: FOM) (OTCQX: FMCXF) is pleased to announce further copper-rich assay results from two new holes drilled into the Tesla Zone, part of Foran’s 100%-owned McIlvenna Bay Property in Saskatchewan. These holes were designed to infill two 200 x 300m gaps in the drill hole spacing near the southern known margins of the Tesla Zone. The holes successfully encountered multiple zones of mineralization as expected, confirming the continuity of the Tesla Zone.

The recent infill drilling program at the Tesla Zone was designed to improve confidence in its grade and continuity, while providing critical data for potential future resource estimates and potential operational expansion scenarios (see the Company’s July 15, 2024 news release). Both drill holes intersected the main mineralized target, followed by thick, copper-rich sections with additional gold content, confirming consistent mineralization across the zone and suggesting areas of higher copper-gold grades. Notably, drill hole TS-24-34 uncovered new copper-zinc mineralization below the current Tesla lenses. This new opportunity highlights the opportunity of additional mineralized lenses, enhancing Tesla’s growth prospects as it advances towards a potential future resource estimate.
Erin Carswell, Foran’s Vice President, Exploration, commented: “This summer our exploration team experimented with new techniques that allowed us to drill Tesla effectively from its western side for the first time, reducing our reliance on ice drilling and providing an exciting glimpse of the southern Tesla ‘footwall’ rocks that we have not had before. As usual with the Tesla Zone, the surprises keep coming. In hole TS-24-34, this included the discovery of a new lens of mineralization sitting just below the main Tesla lenses at the southern end of the zone. In addition, the two holes presented in this release demonstrate yet again how robust the Tesla main lenses can be, boasting multiple zones of high-grade copper and high-grade zinc with pleasing thicknesses of mineralization. Recent results at Tesla underscore its remarkable continuity, unlocking possibilities for future value creation for our operations as we continue to explore this promising zone.”
Key Highlights:
Tesla Zone
Since its discovery in 2022, the Tesla Zone has grown into a significant mineralized body over 1,200m long and 500-700m wide, with 45 intersections (Figure 1) now defining multiple stacked lenses of copper-zinc sulphides and precious metal mineralization. These typically consist of zinc and/or copper-rich massive and semi-massive sulphides and associated copper-rich stringer mineralization and higher-grade breccia zones, plus emerging evidence for zones of gold-only mineralization. The Tesla mineralization currently remains open down dip and along strike for potential continued expansion in the future.
During Summer-Fall 2024, a total of approximately 10,810m of drilling was completed as a series of pilot holes and wedges from four main collars located in the southern part of the Tesla Zone, targeting larger gaps in the current drill hole spacing as we strive to confirm Tesla’s continuity and tenor. Drill holes were collared on land covering approximately 300m of strike length of the zone and drilled from the footwall side using directional drilling to provide perpendicular intersections into the mineralized horizons. A total of seven Tesla pierce points were obtained during the Summer-Fall 2024 program.
This release presents the results of two significant drill holes (TS-24-29 and TS-24-34) from the summer infill drill program. These holes targeted two large gaps in the drilling measuring approximately 200m x 300m along strike and down dip respectively in both instances (Figure 2). Both were successful in confirming the continuity of mineralization in multiple lenses through the southern part of the Tesla Zone. TS-24-34 also intersected an unexpected interval of mineralization in a lower fault slice located below the southern end of the Tesla horizon, proximal to the Bridge Zone. This may correlate with deeper mineralization intersected sporadically in holes such as TS-23-11w2 and TS-24-290. A drilling density map is provided in Figure 2, which shows the locations of the intersections from the summer drill program relative to previous drilling and the importance of these holes for establishing continuity between wider-spaced drill holes.
TS-24-29
TS-24-29 targeted a 200m x 300m gap between existing drill holes where previous drilling had intersected significant zones of mineralization. The hole was drilled from the footwall side of the Tesla Zone, so it intersected the lenses in reverse stratigraphic order. TS-24-29 intersected the expected stratigraphy and mineralized horizons that match well with the surrounding drill holes. The results of TS-24-29 also match well with the results from previously released TS-24-30 (located approximately 200m to the northeast) that returned a combined 36.5m interval of stringer-style mineralization from the upper copper lens, followed directly downhole by the main massive sulphide lens and a thick zone of stringer/breccia-style copper mineralization (see Foran’s October 7, 2024 news release). TS-24-29 intersected the same mineralized package, but in this location the lower copper lens was split into two separate lenses (measuring 9.9m and 26.2m respectively) by a late quartz-feldspar porphyry (QFP) dyke that intruded the stratigraphy from 1280.3-1283.5m. A cross section through the Tesla Zone showing the relationship of TS-24-29 with the surrounding drill holes is provided in figure 3 below.
In detail, TS-24-29 intersected a narrow copper stringer zone at the top of the mineralized interval that was 2.0m in length, grading 0.76% Cu and 0.26 g/t Au. This zone correlates with an upper copper lens that sits above the main massive sulphide lens as was seen in previously released TS-24-30 and throughout much of the Tesla Zone. Directly below the upper copper lens, a 2.4m horizon of massive to semi-massive sulphide was intersected grading 0.64% Cu, 13.64% Zn, 37.1 g/t Ag and 0.27 g/t Au, dominantly consisting of massive pyrite with strong fine-grained sphalerite in the groundmass and minor chalcopyrite mineralization in a strongly chlorite-altered host rock. Below the massive sulphides the hole intersected the lower copper lens, which in this case consisted of several wide copper-rich zones made up mostly of stringer-style mineralization with local breccia zones dominantly consisting of pyrite and chalcopyrite with minor pyrrhotite and sphalerite in a strongly foliated, chlorite and/or sericite altered felsic volcanic host rock. At this location, the lower copper lens is cut by a late QFP dyke which intruded the stratigraphy and effectively splits the lower copper zone into two lenses: a 26.2m interval grading 1.68% Cu followed by a 9.9m interval, below the dyke, grading 1.14% Cu.
Images of high-grade copper mineralization are shown in Figure 3 below, A cross section demonstrating the relationship of TS-24-29 to the surrounding drill holes is provided in Figure 4 on the following page, and detailed composite intervals from the 2024 summer drill program are provided in Table 1.
TS-24-34
TS-24-34 also targeted another large 200 x 300m gap between existing drill holes in an area of limited drilling near the southern end of Tesla. The hole successfully intersected the Tesla Zone in close proximity to the Bridge Zone. This drill hole not only intersected the main Tesla mineralized horizons confirming their continuity, but also intersected an additional zone of mineralization when compared to TS-24-29, which appears to represent faulted offset and a repeat of the Tesla mineralization in an interpreted lower fault slice that is likely related to the folding and faulting that emplaced the Tesla Zone in its current position relative to McIlvenna Bay. This additional zone of mineralization was also intersected in previously released drill hole TS-23-11w2 (see Foran’s May 25, 2023 news release) which intersected a similar contiguous zone of mineralization, consisting of massive sulphide and stringer-style mineralization approximately 350m further downdip that graded 1.93% Cu,1.78% Zn and 31.0 g/t Ag over 4.4m (Figure 6). Additional drilling will be required in this area to define the extent of this mineralized horizon and the relationship of this fault slice with Tesla and the Bridge Zone.
Overall, TS-24-34 intersected a 6.8m interval of the main lens massive sulphide at the stratigraphic top of the Tesla Zone, dominantly consisting of massive pyrite with lesser chalcopyrite and sphalerite in a strongly chlorite altered host rock which graded 1.62% copper and 4.84% zinc. Directly below the massive sulphide, the hole intersected a zone of strong breccia and stringer sulphides over 8.4m which contained significant copper and gold mineralization, grading 2.38% copper and 1.89 g/t Au. This interval speaks to the potential that exists at Tesla to intersect additional high-grade copper-gold intervals as infill drilling continues. This copper-gold intersection was followed by a second broad zone of dominantly stringer-style mineralization over 22.2m, which graded 1.30% copper. Finally, TS-24-34 intersected an additional mineralized horizon in the footwall below Tesla. This footwall mineralization is generally hosted in strongly foliated and locally brecciated units and shows a similar combination of stringer-style mineralization and massive sulphide as seen at Tesla itself, including 1.7m of massive sulphide grading 4.37% copper and 15.47% zinc, followed by multiple narrow zones of breccia and stringer-style copper mineralization below, including: 2.2m grading 1.52% copper, 5.5m grading 1.11% copper and 3.9m grading 0.63% copper.
Photos of the mineralization are shown in Figure 5 and a cross section showing the relationship between TS-24-34 and the surrounding drill holes is provided in Figure 6 below and detailed composite intervals from the 2024 summer drill program are provided in Table 1.

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 and any samples which return results greater than 1.0 g/t Au are re-run using gravimetric 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.
