Vancouver, British Columbia--(Newsfile Corp. - January 28, 2021) -  Riverside Resources Inc. (TSXV: RRI) (OTCQB: RVSDF) (FSE: 5YY) ("Riverside" or the "Company"), is pleased to announce the start of its first drilling program at the Cecilia Project is slated for early February 2021. The work program will test the un-drilled San Jose structure on the Cerro Magallanes target where recent sampling returned values up to 48.3 g/t gold over 0.75 m at surface (see press release of November 18, 2020). As project operator, Riverside Resources has planned a total of 6 drill holes designed to test down to 250 m in depth roughly between 2,200 m and 1,900 m elevation over the Cerro Magallanes rhyolitic dome. This target is one out of 5 major targets on the 7,000 hectares (70 sq. km) claim block in the prolific gold and copper mining region of northern Sonora, Mexico.

Riverside's President and CEO, John-Mark Staude: "We are starting 2021 strong with an exciting drill program at the Cecilia Project. Recent exploration work has demonstrated the potential for high-grade gold mineralization at structural intersections namely the San Jose fault and the Agua Prieta structural corridor. Further work on the other target areas to come later this year as well as continued progress at additional Cerro Magallanes zones."

Recent underground sampling has returned positive results, which demonstrate the value of drill testing the area of Cerro Magallanes. Additionally, geophysical survey work, primarily induced polarization and magnetics have highlighted the targets already identified by the field crews (see press releases dated September 21, 2020 and November 18, 2020). This work shows the significance of the northwestern and northeastern structures as fluid migration paths. The intersection of structures is often where gold bearing fluids are concentrated and could lead to discoveries of high-grade zones. Riverside and Carlyle have planned the drilling program to target, at depth, the high-grade gold system that was identified at surface during its first-phase exploration program (see press release of June 6, 2017).

These drill results are expected to increase our knowledge on potentially larger targets related to the dome margin complex, a deposit type known for hosting multi-million ounces of silver and gold. Analogs include projects such as La Pitarilla Deposit in Durango held by SSR Mining and the San Julian Mine of Fresnillo. While the mineralization at Cecilia is predominantly gold-rich, the flow-dome related Ag-Pb-Zn(-Au) deposits of north-central Mexico represent important geological models for exploration at Cecilia. Drilling of these potential targets will be tested in subsequent drill programs.

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.

Rock samples from the previous exploration programs 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.
