Vancouver, British Columbia--(Newsfile Corp. - December 20, 2023) -
Riverside Resources
Inc.
(TSXV: RRI) (OTCQB: RVSDF) (FSE: 5YY) ("Riverside" or the "Company"),
is pleased to
report on rock sampling and fieldwork from the Cecilia Gold-Silver Project (the "Project") in Sonora,
Mexico.
The results fit within the larger context of a district scale gold-silver composite dome system with
superimposed gold-rich veins.
Past drilling by Riverside intercepted high-grade gold in 4 of the 7 holes
and this sampling over new areas, doubles the strike of the defined mineralization footprint This large
footprint is consistent with other rhyolite dome gold systems including those in New Mexico like Mogollon
and in Sonora like at La India mine of Agnico Eagle.
Key Highlights:
34 rock samples were collected at the primary targets.
22 samples in the main target "Cerro Magallanes" confirming Au grades up
7.3 g/t Au and Ag >
100 g/t.
Five (5) primary structural trends were identified with field data and historic geochemical data
reprocessing.
Updated drilling permits, valid for the next several years, have been obtained along with signed
agreements for surface access over the targets.
Riverside collected rock chip samples from selective areas along 0.8 km length in the Magallanes
Target area that returned gold values in assays up to 7.3 g/t Au and 144 g/t Ag (
Figure 1A., Table 1
).
The sampling confirms the consistent Au grades obtained in past surface workings and diamond core
drilling that includes 24.2m @1.51 g/t Au in CED21-005 by the Company. The mapping and exploration
activities combined with data reprocessing allows the company geologists to define the main structural
trends (Agua Prieta, San Jose, North Breccia, Central and East trends) that are the main mineral
corridors (
Figure 2
).
The structural trends are interpreted as the surface expression of a rooted rhyolite
dome system where higher grades lie at the base of the hill (
Figure 1B
). The geochemical data
obtained, and the geologic mapping are helpful to refine the geological model for the deposit type and
target delineation for the next drill program planned for 2024.

Cecilia Project
The Cecilia project consists of six mineral concessions, collectively covering over 77 sq km (7,739
hectares) in size, thus a large district covered by the Company. The Project is located 40 kilometers
southwest of the Agua Prieta border between Mexico and the USA, and 50 kilometers east of Mexico's
largest mining complex, Cananea copper mining complex producing the largest amount of copper in
Mexico.
In the Cecilia Project, the rhyolitic tuffs and dome complex units intrude and unconformably overlie a
sequence of marine clastic sedimentary rocks consisting of interbedded siltstone and sandstone of the
Cretaceous Cabullona Group which hosts gold mineralization in other portions of northern Sonora as
well as here at Cecilia.
The age of the mineralization obtained by Riverside yielded ca. 18 Ma using U-
Pb in zircons in syn-volcanic mineralized rhyolite flow dome in the top of the sequence. This age for
mineralization tied to magmatism has also been reported in large Au camps in Arizona (e.g. Oatman
area, DeWitt et al.,1986).
Riverside work in the district has developed additional targets including the Cruz 1, Cruz 2, Cruz 3, Casa
de Piedra, Los Llanos, and Magallancito targets (Figure 3).
These targets represent different levels of
exposure and make the Cecilia project a potential district for multiple gold discoveries.

Qualified Person & QA/QC:
The scientific and technical data contained in this news release pertaining to the Cecilia Project was
reviewed and approved by Julian Manco, P.Geo, a non-independent qualified person to Riverside
Resources focusing on the work in Sonora, Mexico, who is responsible for ensuring that the information
provided in this news release is accurate and who acts as a "qualified person" under National Instrument
43-101 Standards of Disclosure for Mineral Projects.
Rock samples from the exploration program discussed above at Cecilia were taken to the Bureau
Veritas Laboratories in Hermosillo, Mexico for fire assaying for gold. The rejects remained with Bureau
Veritas in Mexico while the pulps were transported to Bureau Veritas laboratory in Vancouver, BC,
Canada for 45 element ICP/ES-MS analysis. A QA/QC program was implemented as part of the
sampling procedures for the exploration program. Standard samples were randomly inserted into the
sample stream prior to being sent to the laboratory.
