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.

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.

represent previously unidentified mineralization in the
300m between the Tesla Mineralization
and the McIlvenna Bay Deposit.

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.
Foran's northern claims shown on an aeromagnetic map with
locations of targets selected for drilling and geophysical follow
up work over the current program and subsequent years.
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.
