Vancouver, British Columbia - 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 (
