Below the No. 3 Zone at the Levack Mine in
Sudbury, Ontario
Sudbury, Ontario--(Newsfile Corp. - August 28, 2025) - Magna Mining Inc. (TSXV: NICU) (OTCQX:
MGMNF) (FSE: 8YD) ("Magna" or the "Company") is pleased to provide an update on exploration
activities and assay results from ongoing exploration at the past-producing Levack Mine, located in the
North Range of the Sudbury Basin, northeastern Ontario, Canada (Figure 1). Drillhole FNX6083-W1 was
drilled to test an area 140 metres below drill hole MLV-25-14A (see
news release dated July 9, 2025
)
which intersected 2.6% copper, 8.1% nickel and 17.8 g/t platinum + palladium + gold over 0.6 metres.
Drillhole FNX6083-W1 intersected multiple mineralized intervals ranging from veinlets of copper rich
chalcopyrite and bornite, to more than 1 metre of massive chalcopyrite. Magna is referring to this target
area in the footwall of the No. 3 Zone as the Rob's 2 ("R2") target.
Highlights from the new assay results include:
FNX6083-W1
12.8% Cu, 0.6% Ni, 31.8 g/t Pt+Pd+Au over 2.6 metres
Including
29.2% Cu, 0.9% Ni, 53.0 g/t Pt+Pd+Au over 1.0 metres
And
25.5% Cu, 1.8% Ni, 26.3 g/t Pt+Pd+Au over 0.5 metres
Dave King, SVP Exploration and Geoscience stated, "Prior to acquiring the Levack Mine in Q1 of this
year, we believed there remained the potential to discover another significant, high-grade copper, nickel
and precious metal deposit in the footwall environment of the property. The drilling results announced in
July from drillhole MLV-25-14A, combined with those released today which includes a subinterval of
29.2% copper and 29.9 g/t gold, along with 15.8 g/t palladium, 7.3 g/t platinum and 0.9% nickel over 1.0
metre, are encouraging and appear to confirm our belief that the prospective exploration environment at
Levack remains under-explored. There are notable similarities in the geology and vein mineralogy
intersected in our recent drilling with the upper levels of the Morrison Footwall Cu-PGE Deposit. We will
continue to leverage our experience in the discovery and understanding of the geological controls within
the Morrison Deposit to further advance the R2 exploration target. We are looking forward to providing
additional assay results as we continue to define the extent of the R2 mineralization."
There are currently two surface diamond drills operating at the Levack Mine, one completing three
shallow infill and metallurgical drillholes on the Main Ni-Cu Zone in support of the Levack Restart Study,
and a second drill exploring the footwall environment between the No. 3 Ni-Cu Zone and the Morrison
Footwall Cu-PGE Deposit, with another wedge hole targeting the area north of the intersections reported
today. Recall, drillhole MLV-25-14A (reported
on July 9, 2025
) was targeted beneath the No. 3 Ni-Cu
Zone and was designed to test for subvertical mineralization, striking parallel to the Fecunis fault, based
on Magna's geological interpretation of this area, and relationship of these structures to the geological
controls on the Morrison Deposit. Based on the results of MLV-25-14A and continued geological
interpretation, historical drillhole FNX6083 was deepened to provide a geophysical platform, and survey
results from this hole confirmed Magna's interpretation of the mineralization in this area. Drillhole
FNX6083-W1 was a wedge hole designed to test approximately 140 metres down-dip of the Ni-rich
veins in MLV-25-14A and successfully intersected significant intervals of disseminated to stringer
copper mineralization and two massive chalcopyrite veins. The massive sulphide veins graded 29.2%
Cu, 0.9% Ni, 53.0 g/t Pt + Pd + Au over 2.6 metres and 25.5% Cu, 1.8% Ni, 26.3 g/t Pt + Pd + Au over
0.5 metres. Assays are summarized in Table 1 and drillhole collar information is presented in Table 2.
Morrison Deposit Geology and Footwall Copper-Precious Metals Mineralization
Mineralization intersected to date within the R2 target area shows similarities to the mineralogical trends
seen in the upper levels of the Morrison Footwall Cu-PGE Deposit, located approximately 600 metres to
the south-west in the Levack Mine. The Morrison Deposit occurs vertically beneath the No. 7 Contact
Zone (Figure 2) and was discovered by FNX Mining in 2005 and subsequently developed and mined
until 2019. Similar to other copper and precious metals-rich footwall deposits along the North Range of
the Sudbury Basin, the massive sulphide veins of the Morrison Deposit vary from less than 1 metre to
more than 6 metres in thickness and consist of chalcopyrite, cubanite, pentlandite and millerite with high-
grade precious metal values. The Morrison Deposit has a distinct vertical mineralogical trend,
transitioning from Ni-rich, pentlandite and pyrrhotite veins in the upper levels of the Rob's Zone, to Cu-
rich chalcopyrite veins that have increasing platinum, palladium, gold and silver concentrations at depth.
The upper nickel-rich veins within the Rob's Zone were commonly under 1 metre to 2 metres in thickness
and under 150 metres in strike length. The relatively narrow, nickel-rich veins of the Rob's Zone
continued for approximately 150 metres downdip, before transitioning to narrow Cu-rich chalcopyrite
dominated veins. The central portion of the Morrison Deposit contained chalcopyrite veins up to
approximately 6 metres thick, within mineralized areas extending over 250 metres along strike. The
mineralogical zonation between the nickel-dominated veins in drill hole MLV-25-14A and the copper and
precious metals-rich veins reported today in drillhole FNX6083-W1 from the R2 target area appears to
be consistent with that seen in the Morrison Deposit. See Figure 3 for detailed examples of the
mineralization in the upper levels of the Morrison Deposit and associated vein grades.
Levack Exploration Plan
Magna is focusing its near-term exploration program at the Levack Mine on this prospective footwall
environment, continuing to test the lateral and downdip extent of the R2 target and other high-priority
Sudbury Breccia units that have the potential to host copper and precious metals-rich footwall deposits.
Initial drilling on the R2 target will be designed to confirm and refine the geological model and define the
extent of mineralization. Downhole geophysical electromagnetic surveys will continue to help target
drilling within the most conductive areas of the mineralized system.
Drilling will ramp up at Levack over
the remainder of the year with two underground diamond drills mobilizing within the coming weeks.

Qualified Person for Technical Information
The scientific and technical information in this press release has been reviewed and approved by David
King, M.Sc., P.Geo. Mr. King is the Senior Vice President, Exploration and Geoscience for Magna
Mining Inc. and is a qualified person under National Instrument 43-101.
Quality Assurance and Control
Sample QA/QC procedures for Magna have been designed to meet or exceed industry standards. Drill
core is collected from the diamond drill and placed in sealed core trays for transport to Magna's core
facilities. Levack drilling utilizes NQ sized core and McCreedy West utilizes BQTK sized core. The core
is then logged, and samples marked in intervals of up to 1.5m. Levack drill core is split and sampled ½
core, and McCreedy West is whole core sampled. Samples are then put into plastic bags with 10
bagged samples being placed into rice bags for transport to SGS Laboratories in Garson, Ontario for
preparation, which are then shipped to Lakefield, Ontario for analysis.
Samples are submitted in batches
of 50 with 4 QA/QC samples including, 2 certified reference material standards and 2 samples of blank
material.
