Riverside Resources and Carlyle Commodities Report Additional High-grade Gold of 3.3 Meters of 3.37 g/t Gold at the Cecilia Project, Mexico

Drill Results

Riverside Resources and Carlyle Commodities

Report Additional High-grade Gold of 3.3

Meters of 3.37 g/t Gold at the Cecilia Project,

Mexico

Vancouver, British Columbia--(Newsfile Corp. - April 27, 2021) -

Riverside Resources Inc. (TSXV:

RRI) (OTCQB: RVSDF) (FSE: 5YY) ("Riverside" or the "Company"),

is pleased to report the

second batch of results from the drilling program at the Cecilia Project in Sonora, Mexico where work is

on-going with partner Carlyle Commodities Corp (CSE: CCC). Following the first batch of results

announced April 15, 2021, Riverside and Carlyle are now reporting additional anomalous intercepts in

the last two drill holes of the Phase I drilling program, including

3.3 m of 3.37 g/t Au

at the North Breccia

Target (CED21-006) and 3.05m of 0.67 g/t Au at the Central Target (CED21-007). Surface and shallow

sub-surface expression of the mineralization and alteration in drill holes appear to demonstrate the top of

a robust hydrothermal system, which could be expanded at depth, with expectation of a more developed

gold and silver system based upon the geologic modeling and logging of these core holes.

Riverside's President and CEO, John-Mark Staude:

"

We are pleased to see this program progress

with Carlyle Commodities Corp. where we are shareholders and delighted to see the exploration

program return higher grade gold. These new results continue to build upon the historical work by

Cambior and others, combined with the current 2021 drill campaign which is beginning to show new

target ideas, new gold mineralization controls, and widening the perspective for discoveries.

We look

forward to additional drilling and providing more discovery opportunities at the Cecilia Project with our

partner Carlyle Commodities."

The mineralization at the Cerro Magallanes dome appears to be strongly related to silicification and

oxidation. Fault margins are described by metric-scale wide zones of stockwork to breccia with large

amounts of hematite, goethite and oxidized pyrite. The matrix can be partly infilled with chalcedonic or

milky white quartz, which in hydrothermal systems is well known to be shallow in the system features (see

Figure 1

below). Additionally, in hole CED21-001 and along surface, fluorite and grey quartz are present

and support the Company's theory that this represents the upper-part of the system.

fault. Sample taken in hole CED21-003, from 31.15 m to 32.20 m.

mineralized targets with holes CED21-006 and CED21-007 from this news release for which

alteration and gold mineralization are intersected in various holes during the phase

campaign of Riverside and Carlyle. The targets appear open beneath these shallow initial

intercepts for possible further delineation.

Drill hole CED21-006 is perpendicular to hole CED21-005 which was announced earlier this month with

22 m @ 1.5 g/t Au with indication that the holes are beginning to develop different dimensions and are

open for further drilling as all intercepts have been very shallow to date. The CED21-007 is the first hole

by Riverside into the Central Target area and further follow up will now be warranted as gold have been

found on structures and previous small-scale mining has been developed along various trends. The

Riverside and Carlyle exploration program is on track and plans are to continue with more drilling and

building upon these positive results from the Phase I program at the Cerro Magallanes dome as well as

over the broader district, which includes at least 6 additional regional targets.

Qualified Person & QA/QC:

The scientific and technical data contained in this news release pertaining to the Cecilia Project was

reviewed and approved by Freeman Smith, P.Geo, a non-independent qualified person to Riverside

Resources, who is responsible for ensuring that the geologic 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.

Riverside completed a QA/QC program as part of the drilling program with about 10% of the samples

assayed being control samples. Standards and blanks were inserted approximately every 20 samples

and duplicates every 30 samples. Drill samples 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.
