Tesla Assays Outline Continuous High-Grade Mineralization and New Bridge Zone Results Highlight Further Growth
Tesla highlight intercepts include 44m at 2.9% CuEq
Bridge Zone's New Mineralized Intercepts Affirm Expansion Opportunity
Drilling of Priority Regional Targets Ongoing
VANCOUVER, BC, Oct. 5, 2023 /CNW/ - Foran Mining Corporation (TSX: FOM) (OTCQX: FMCXF) ("Foran" or the "Company") is pleased to report additional assay results from the ongoing 2023 drill program at the 100%-owned McIlvenna Bay Complex (the "Project") in Saskatchewan. Drilling has confirmed multiple, wide zones of mineralization at Tesla and demonstrated continuity between Tesla and McIlvenna Bay in the newly discovered Bridge Zone.
Key Highlights:
Drilling continues to identify significant intercepts of high-grade mineralization at Tesla with assays from hole TS-23-12 intersecting six massive and semi-massive sulphide zones, including:
44.0m grading 1.08% Cu, 5.09% Zn, 32.3 g/t Ag and 0.39 g/t Au (2.88% CuEq); including 21.1m grading 1.28% Cu, 8.22% Zn, 40.1 g/t Ag and 0.38 g/t Au (4.03% CuEq)
11.9m grading 0.84% Cu, 9.17% Zn, 46.4 g/t Ag and 0.36 g/t Au (3.93% CuEq); including 6.0m grading 0.86% Cu, 11.36% Zn, 52.7 g/t Ag and 0.40 g/t Au (4.66% CuEq)
8.8m grading 0.13% Cu, 12.45% Zn, 103.7 g/t Ag and 0.44 g/t Au (4.58% CuEq); including 2.4m grading 0.12% Cu, 25.78% Zn, 143.7 g/t Ag and 0.22 g/t Au (8.61% CuEq)
Tesla mineralization has been defined along 750m strike and remains open in all directions for further expansion.
Recent drilling in the Bridge Zone continues to suggest a key connection between Tesla and the McIlvenna Bay Deposit. This zone has the potential to be a significant area for growth going forward. Results from MB-23-289 from the Bridge Zone include:
13.0m grading 0.87% Cu, 4.83% Zn, 39.9 g/t Ag and 0.17 g/t Au (2.52% CuEq); including 1.7m grading 1.12% Cu, 12.65% Zn, 40.0 g/t Ag and 0.24 g/t Au (5.13% CuEq)
3.3m grading 0.44% Cu, 5.27% Zn, 23.2 g/t Ag and 0.24 g/t Au (2.22% CuEq); including 1.4m grading 0.80% Cu, 8.98% Zn, 31.6 g/t Ag and 0.33 g/t Au (3.75% CuEq)
The 2023 regional exploration program is now underway, including helicopter-supported drilling of several high priority geophysical and geological targets in close proximity to the McIlvenna Bay Complex. These targets are interpreted to lie along the prospective structural and stratigraphic corridors identified by Foran from geophysical and geological interpretations.
Erin Carswell, Foran's Vice President, Exploration, commented: "With further substantial intersections of zinc, copper, and precious metals mineralization drilled at Tesla northwest, our confidence in grade continuity grows with every exciting metre of core. We are eager to commence our winter drill program as it will offer us the opportunity to define this higher-grade target area more extensively. Meanwhile the Bridge Zone continues to impress with a second intercept of high-grade zinc and copper and precious metals mineralization confirmed between Tesla and McIlvenna Bay, further reinforcing the growth potential of this new discovery. In tandem, several regional targets are now being tested to conclude the fall program as we leverage insights from our ongoing orebody knowledge studies and strive to unlock the significant mineral potential of our wider district."
Tesla Zone Drilling – Hole TS-23-12
Assays returned this month from the current drilling at Tesla have continued to substantiate the high tenor of mineralization to the northwest, with multiple intercepts in hole TS-23-12 returning grades up to 25% zinc in conjunction with significant silver and copper. Mineralization occurs across multiple thick intervals, although true thicknesses may not be represented in this hole due to the steep angle of drilling required to intersect the orebody from land near the edge of Hanson Lake. Upcoming winter drilling of Tesla from the ice will allow drilling to be conducted at more optimum angles. Nevertheless, the continuity of the high grades in TS-23-12 is highly significant and may represent a lateral continuation of thick intercepts recorded in hole TS-23-10 immediately to the south (see April 20, 2023 news release). Figure 1 above shows the locations of Tesla drill holes completed to date.
TS-23-12 intersected six massive and semi-massive sulphide lenses, several associated stringer and breccia zones, and multiple intervals with elevated gold and silver. Generally, the massive to semi-massive sulphide lenses are similar throughout the hole consisting of 40-50% fine to locally coarse-grained pyrite in a brown to red fine-grained sphalerite-rich groundmass with local pyrrhotite and chalcopyrite. These zones of mineralization are generally hosted in chlorite and/or sericite-altered units, although hole TS-23-12 also intersected several zones of mineralization associated with carbonate alteration and veining in gabbro and interbedded mafic units. This style of mineralization was intersected in several of the previous holes at Tesla and indications are that it is becoming somewhat more prevalent as the exploration progresses to the north.
TS-23-12 was drilled as an 80m step-out from TS-23-10 which was the last hole completed at the north end of the Tesla Zone during the winter program (see Figure 2). A detailed listing of the composite intervals from the hole are provided in Table 1 below. The current drill program continues to better define the mineralized footprint at Tesla with a total of 8,177m of drilling completed to date.
Three additional wedged holes have been completed using TS-23-12 and TS-23-13 as pilot holes. These holes have been designed to continue to expand the footprint of the mineralization and provide additional understanding of the relationship between the mineralized zones. Assay results from these holes are pending and will be reported when they have been received and interpreted.

To date no metallurgical test work has been completed on the Tesla mineralization. |
Bridge Zone Drilling – Hole MB-23-289
Two drill holes have now been successfully completed in the Bridge Zone area, each of which has successfully intersected multiple copper and/or zinc-rich horizons within the 300m-wide window that lies between the southernmost drilling at Telsa and northernmost drilling at the McIlvenna Bay Deposit. The results from this drilling, including detailed geological logging, geochemistry from TruscanTM analysis and structural data from oriented core, indicate a close link between Tesla and the McIlvenna Bay Deposit and continues to suggest that a fold may connect the two deposits.
MB-23-289 intersected similar tectonostratigraphy and host rock lithology as McIlvenna Bay. The hole intersected two mineralized zones approximately 100m to the northwest of previously released MB-23-287, that appear to correlate with the Main Lens massive sulphide and overlying Lens 3 in the deposit. MB-23-289 intersected a 13m interval of massive and semi-massive sulphides starting at 1144.2m, consisting of medium to coarse grained pyrite in a fine-grained brown sphalerite-rich groundmass with local chalcopyrite and pyrrhotite hosted in a strongly chlorite-magnetite-altered unit. Approximately 164m below this interval the Main Lens massive to semi-massive sulphide was intersected, again consisting of medium- to coarse-grained pyrite in a fine-grained brown sphalerite-rich groundmass similar to previous holes, with the mineralization hosted in strongly chlorite altered rocks logged as chlorite schist.
In both MB-23-287 and 289 a generation of overprinting low iron, high zinc sphalerite is observed which, where present, leads to enhancement of zinc grades. This style of mineralization is new for the McIlvenna Bay Complex and is the subject of ongoing work to determine its controls and possible focus.
Figure 2 below highlights a three-dimensional view of the location of the Tesla and Bridge Zone holes, and Table 2 presents detailed composites from the Bridge Zone drilling.

Regional Targeting Program
Foran has now transitioned to its regional, helicopter-supported greenfields drilling program with two drills dedicated to testing targets within a 50km radius of McIlvenna Bay, while one drill remains dedicated to continuing the Tesla expansion drilling. Regional target areas are continuously generated by combining the results of ongoing orebody knowledge studies with airborne geophysical, geological and structural interpretations, which allow us to identify prospective corridors for ground and/or borehole EM follow-up to define drill targets. Of the highest-priority targets selected for this program, two are located close to McIlvenna Bay near Hanson Lake (Ada and Higgs targets) and one is located on the Bigstone Property (Maxwell target). The locations of these are shown in Figure 3, along with further initial drill-ready and geophysical follow-up targets that we have identified for testing in subsequent programs. Foran has recently received two-year exploration permit approvals (drilling and geophysics) covering the planned regional exploration target areas and further Tesla drilling from the Saskatchewan Ministry of Environment which will facilitate planned and ongoing exploration programs into the future.
To aid with future target generation, Foran has now completed its regional Falcon gravity gradiometry survey over the McIlvenna Bay and Bigstone properties. This data will be an important regional interpretation and targeting tool when used in conjunction with aeromagnetic and electromagnetic data collected during the ongoing regional HeliTEM survey. We have also commenced flying the VTEM survey across our southernmost claims, which will serve as a primary targeting tool across these areas. This investment in the collection of detailed high resolution geophysical data demonstrates our belief in the potential of the Hanson Lake District to host additional discoveries and will facilitate ongoing exploration as we continue to advance our geological understanding and exciting pipeline of prospects.

Quality Assurance and Quality Control
Drilling was completed using NQ size diamond drill 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.
