Riverside Resources Options Prospective
Ground with past Drilling to Double the Size of
the Jacket Property in Central British
Columbia
Vancouver, British Columbia--(Newsfile Corp. - January 21, 2026) - Riverside Resources Inc. (TSXV:
RRI) (OTCQB: RVSDF) (FSE: 5YY0) ("
Riverside
" or the "
Company
") is excited to announce that it has
used some of the recent capital raise, and more importantly, has doubled the size of the Jacket Property
by optioning the Redtop property. The combined project will now be referred to as the "Red Jacket
Project." The decision to acquire the Redtop property followed Riverside's initial exploration program in
the later part of 2025. The Redtop property is contiguous with, and immediately north of Riverside's
Jacket claims.
The Red Jacket is easily accessed via paved highway and then by logging road, approximately 15 km
east of Clearwater and 115 km north-northeast of Kamloops in central British Columbia. The project is
north of the Taesko Mines' feasibility-stage Yellowhead Copper Project, which hosts a large Cu-Zn-AG-
Au reserve and is considered a potential near-term future mine. The Redtop property hosts at least three
main outcropping and previously drilled polymetallic mineral occurrences and is located within a well
mineralized prospective belt of volcanogenic massive sulphide ("VMS") deposits. These occurrences
display classic features characteristic of the large Canadian deposits of this deposit type and are similar
to Taseko's copper resource 10km to the south in the same Eagle Formation, Cambrian age geology.
The Company reviewed the historical work and expanded on historical soil sampling and trenching this
autumn. This work outlines a 4 km long northwest-southeast trend that includes the Redtop, Snow and
Sunrise showings. Riverside completed target sampling in late 2025 to validate mineralization in areas
of past trenching and to strengthen confidence in the project's best-known zones, where 2026
exploration work can be done on the consolidated project.
Riverside's results confirm the presence of
meaningful polymetallic grades at surface supporting the view that the Red Top horizon merits
systematic follow-up work to evaluate continuity and prioritize the most prospective sections for the next
phases of exploration.
"Red Jacket is a compelling project in our British Columbia portfolio, and we have expanded our
property footprint by acquiring the Redtop project," said John-Mark Staude, CEO of Riverside
Resources. "Our 2025 sampling returned high-grade polymetallic results from historical trenches,
reinforcing that the Redtop–Snow–Sunrise trend warrants drill testing and further expansion, particularly
in light of Taseko's advanced-stage copper development project in the same geology immediately to the
south. Red Jacket is positioned in a proven district that has seen significant past exploration and mining
activity. We believe we are in a strong position to advance value generating work across the expanded
claim package and pursue additional discoveries as we work to discover new mineral resources for the
Riverside".
Red top deal terms:
The Redtop claims are located north of, and contiguous with, Riverside's Jacket claims. Riverside has
signed an option agreement to acquire the claims from a private group called "Geo Exploration Scouts".
The terms of the option agreement are summarized in the table below.

In addition to the cash and work expenditures, the Optionor will retain a 0.45% Net Smelter Returns
Royalty, which is subject to $1,000,000 buyout. Riverside will have the first right of refusal on any sale or
transaction involving the royalty. If an exploration permit cannot be obtained within 4 years of signing the
definitive agreement, the project will be returned to optionor.
No payments or work commitments will be
required until a drill permit is acquired and all necessary agreements are in place to proceed with drilling
and related exploration.
The option agreement is subject to TSXV approval.
Historical Exploration Work
The historical geochemistry, geology and geophysics, including that on the optioned claims, continues to
add value for the Company. This builds on key work completed by companies such as Placer Dome,
and precedes the work by Taseko, which now controls the large copper resource, reserve and feasibility-
staged property to the south. At Red Jacket, the combined and integrated historical soil sampling
surveys confirm the continuity of the known mineralized bands, and can be traced consistently within a
defined belt over 4km long northwest-southeast horizon that includes the known MinFile showings:
Redtop, Snow and Sunrise (
Figure 2
). The prospective horizon hosting these showings has received
minimal drill testing and the entire length of the horizon is considered a target.
Historical work by Placer
Dome Inc. shows a zinc-in-soil anomaly enveloping the areas of known mineralization, similar to the
Yellowhead deposit in its early exploration history. This linear, southeast trending anomaly is roughly
parallel to a potassium enrichment zone shown in the K% and eTH/eK radiometric images (
Figure 1
). In
addition, the north-trending linear magnetic highs noted on the Total Magnetic Intensity image are likely
showing mafic dikes and/or structures. Together, the airborne detailed magnetics help in refining targets,
and the coincident soil anomalies provide immediate areas of interest with district-scale potential.
Linking the historical showings with the consolidated land package positions the Company to advance
systematic work aimed at unlocking value for shareholders.

2025 Riverside Samples
Riverside collected samples before snowfall ended the program, and Riverside can now return early in
the spring to continue follow-up work on the Redtop claims, supported by high-grade assay results. The
sampling confirmed the historical range of high-grade values in the area of past trenching that are easily
accessible by recent logging roads. These areas include zones affected by pine beetle tree kill, which
has created extensive new exposures that were not available even a decade ago. Three main showings
were sampled during the autumn field work, while the actual Redtop showing already had snow cover
and will be a priority target for early 2026 field work.

*Grab samples were taken in November of 2025 by Riverside Personnel.Grab samples by their nature are selected samples and the results for these
selected samples may not reflect underlying mineralization.
The area of the Sunrise Occurrence contains at least six trenches, showing multiple thin bands of semi-
massive to massive sulphide hosted in quartz-sericite schist. Bedding at Sunrise dips shallowly (<10°) to
the east, as the showing is located in the nose of the anticline. Four samples were collected and
assayed from the Sunrise trenches, with elements from the four samples
returning up to 1.1% lead, up to
24% Zn
, up to 0.1% Cu, and up to
128 g/t Ag
and 0.8 g/t Au (Table 1).
The Snow Showing comprises of a small trench that hosts shallowly north-dipping, rusty quartz-sericite
schist. A poorly exposed semi-massive sulphide layer of unknown thickness is present locally with a
cherty component. This occurrence also features crosscutting, chalcopyrite-bearing veinlets. One sample
was collected and assayed in 2025 that returned:
0.4% Cu, 2.8% Pb,
0.7% Zn, 0.3 g/t Au, and
217 g/t
Ag
(Table 1).

Geological Setting
The property is situated within the pericratonic Kootenay Terrane in the southeastern Cordillera,
immediately outboard (west) of ancestral North America. This terrane is composed primarily of lower to
mid-Paleozoic sedimentary and volcanic rocks and is correlative with the productive Yukon-Tanana
Terrane in Alaska and the Yukon Territory. More specifically, the area is underlain by Lower Cambrian to
Mississippian deformed and metamorphosed sedimentary and volcanic rocks of the Eagle Bay
Assemblage. The assemblage has been intruded by the Upper Devonian to Permian felsic Raft and
Baldy batholiths. Devonian to Permian mafic volcanic and intrusive rocks of the Fennell Formation have
been thrust over the western part of the assemblage. Government mapping shows the property to be
underlain by the "EBQ" unit of the Eagle Bay Assemblage, possibly of Lower Cambrian age.
The Eagle
Bay is the assemblage
that hosts Taseko Mines' copper reserves and feasibility-staged property at
Yellowhead.
Eagle Bay has been a mining target and productive geologic VMS unit and Riverside has
targeted this unit and specific horizons for this mineral option acquisition. The mineral occurrences on
adjacent or nearby properties within the Eagle Bay Assemblage may not be reflected on the Company
controlled properties. Further exploration work will continue during H1 of 2026 on the Company property.
Regional VMS Context
VMS deposits are abundant within the Eagle Bay Assemblage and adjacent rocks:
The Chu Chua Cyprus-type deposit occurs in the nearby Fennell Formation and has an inferred
mineral resource of 2.29 Mt @ 2.11% Cu, 0.30% Zn, 9.99 g/t Ag and 0.50 g/t Au.
1
Samatosum is a stockwork zone mined by Inmet Mining between 1989 and 1992; the deposit
totaled 0.63 Mt grading 1035 g/t Ag, 1.2% Cu, 1.7% Pb, 3.6% Zn and 1.9 g/t Au.
2
The Rea deposit contains two massive sulphide lenses with a combined resource of 0.38 Mt @
0.33% Cu, 2.2% Pb, 2.3% Zn, 6.1 g/t Au and 69.4 g/t Ag.
3
The Homestake deposit is largely contained in barite lenses, with estimated resources in 1973 of
1.01 Mt @ 240 g/t Ag, 2.5% Pb, 4.0% Zn, and 0.55% Cu.
4
The Harper Creek metamorphosed VMS deposit (817 Mt @ 0.28% Cu, 0.03 g/t Au and 1.3 g/t Ag)
is located in the Eagle Bay Assemblage approximately 15 km southeast of the property and known
as the Yellowhead.

The Property has seen intermittent exploration and was examined by two major companies, INCO and
Placer Dome Inc. INCO undertook geological mapping, soil sampling, ground magnetometer and limited
VLF surveying in 1977; this was their only program on the Property. Placer completed extensive soil
geochemistry and lesser EM, magnetics and geological mapping from 1983 to 1989. They drilled four
short holes but recommended drilling an additional 13 holes which were never drilled. Other work on the
Property over the years has not been systematic. The Property is considered under-explored and ready
for progressing work, particularly with the recent logging that has increased the access and exposures.
The Harper Creek deposit, 10 km to the southeast, is part of the Eagle Bay Formation's metavolcanic
and metasedimentary rocks. Geologically, it lies on the western margin of the Omineca Belt within the
Kootenay Terrane. The mineralization is found within tabular zones in various phyllites and quartzites,
including quartz-sericite, chloritic, carbonaceous phyllite, and sericitic quartzite. Mineralization occurs as
disseminations and patches along rock foliations, and within quartz and quartz-carbonate veins. It is
associated with minor sphalerite, galena, arsenopyrite, molybdenite, tetrahedrite-tennantite, bornite, and
cubanite, with occurrences of magnetite.
The Harper Creek Fault separates the deposit into east and west domains. The west domain's
mineralization is hosted within three horizons of volcanic and volcaniclastic units. Mineral Reserves:
According to a January 2020 NI 43-101 Taseko Mines technical report, the proven and probable mineral
reserves are estimated at 817 million tonnes at a 0.17% copper cut-off grade. The average grades are:
Copper (Cu): 0.28%; Gold (Au): 0.030 g/t; Silver (Ag): 1.3 g/t.
The project is planned as a large open-pit
mine with a 25-year life and a processing capacity of 90,000 tonnes of ore per day. Further technical
specifications are available in the Technical Report on the Mineral Reserve Update at the Yellowhead
Copper Project on the Taseko Mines website.
