Riverside Resources Regains 100% Control of

the La Union Gold-Silver-Zinc Project After

More than US$500,000 in Partner Funded

Exploration and Consolidation Work

Vancouver, British Columbia--(Newsfile Corp. - October 3, 2022) -

Riverside Resources Inc.

(TSXV:

RRI) (OTCQB: RVSDF) (FSE: 5YY)

("Riverside" or the "Company"),

has been reimbursed for past

taxes and fees with more than USD$500,000 of new mineral exploration and consolidation work

completed to-date as per the option agreement announced in May 2022 with Hochschild Mining Corp.

Exploration work at La Union Project (the "Project") has returned gold ("Au") values greater than two

ounces per ton ("oz/t"), silver ("Ag") values over 20 oz/t and up to six percent zinc ("Zn") (see press

release dated October 6, 2021). There are four primary drill targets that were defined from 2022

exploration programs, however Minera Hochschild Mexico SA de CV ("Hochschild") has decided not to

proceed with the option and further exploration spending at La Union for corporate strategy reasons.

Riverside's President and CEO, John-Mark Staude, commented: "We appreciate the collaboration with

Hochschild and the contributions in advancing La Union. The Project has clear exploration upside and

while the timing doesn't currently work to continue with this partnership, we still see an opportunity to

create significant value at La Union and will integrate all of the data and evaluate new partnership

opportunities in the near future."

Riverside is now free to move ahead with seeking other partners for the 26 km sq project located in the

favorable limestone carbonate replacement (CRD) belt of western Sonora, Mexico. The Union Project

displays mineralized gold-silver-zinc-lead rich mantos (tabular bodies) hosted in the Precambrian

limestone strata with mineralized chimneys cutting upward into the Cambrian limestone with a

surrounding halo of alteration, dolomitization, and silicification. Furthermore, the previous mining

activities did not treat sulfides at the time, providing another untested mineralization style for future

drilling.

The latest exploration investment helped to define the main structural and lithological controls of the

mineralization which is fundamental for successful exploration of the Union district. Technical work has

defined NNW-oriented subvertical structures that acted as conducts for mineralizing fluids and which

interacted with thick (> 200m) highly reactive carbonate host rocks (Caborca and Arpa Formations)

delineating three main CRD target areas (Figure 1).

Target 1: This area displays a mineral and alteration footprint larger than 2 x 1.5 km, with new

geochemistry yielding 7 - 10g/t Au, 170 - 279 g/t Ag and Zn ranging from 1.2 - 11.6 % (Figure 1).

Target 2: New surface geochemistry in this area returned 2.5 - 7 g/t Au, up to 73 g/t Ag and 3.2 %

Zn.

Target 3: is close to la Famosa Mine where the previous sampling returned ~2 oz/t Au, ~26 oz/t

Ag, and > 4% Zn (Oct 6, 2021, news release).

Newly completed regional and local structural geology has been aided through stratigraphic geologic

work by the Company which provides a district-wide targeting cross-section that helps for planning future

drilling as shown below.

Exploration work completed to-date includes extensive field mapping, sampling, and geochemistry. The

newly mapped and sampled areas show alteration features typical of CRD targets and particularly the

gossan oxidation of potential sulfide bodies at shallow depths (<100m) that remain wide open for

relatively low-risk, high-potential exploration. The Company has been able to link various units into the

broader stratigraphic units of the Sierra El Viejo and overall Caborca Geologic Terrane, which had

previous scientific investigations, but limited CRD drill testing so far sets up the project for immediate

further exploration discovery. To that effect, a first phase of drilling could include 10 drillholes to test the

continuity of the gossans and target areas along the NNW corridor shown in Figure 1 above. Therefore,

the Project is now nicely set up for the next exploration steps, which could include geophysics and

drilling, and the Company looks forward to exploring new partnership opportunities.

Qualified Person & QA/QC:

The scientific and technical data contained in this news release pertaining to the La Union 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 the La Union Project 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 using 4-acid digestion methods. 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.

About Riverside Resources Inc.:

Riverside is a well-funded exploration company driven by value generation and discovery. The Company

has over $4M in cash, no debt and less than 80M shares outstanding with a strong portfolio of gold-silver

and copper assets and royalties in North America. Riverside has extensive experience and knowledge

operating in Mexico and Canada and leverages its large database to generate a portfolio of prospective

mineral properties. In addition to Riverside's own exploration spending, the Company also strives to

diversify risk by securing joint-venture and spin-out partnerships to advance multiple assets

simultaneously and create more chances for discovery. Riverside has properties available for option,
