Riverside Stakes the Duc Project in the Porcupine Mining District, Ontario

Vancouver, British Columbia--(Newsfile Corp. - January 23, 2023) - Riverside Resources Inc. (TSXV: RRI) (OTCQB: RVSDF) (FSE: 5YY) ("Riverside" or the "Company"), is pleased to announce it has staked additional claims in northwestern Ontario and acquired the Duc Project ("the Project"), located south of the town of Kapuskasing, part of the Porcupine Mining District. The Project is roughly 600 hectares in size and located west of the past producing Agrium Ltd. carbonatite phosphate mine, within the Wawa Subprovince, which hosts several rare earth element occurrences and orogenic gold deposits. Gold typically occurs in older folded rocks associated with larger northeast trending structures related to Kapuskasing Structural Zone ("KSZ"). The Wawa Subprovince is host to multi-million-ounce large gold mines that include Alamos Gold's Island Gold Deposit and Argonaut's Magino Gold Deposit amongst others.

Riverside's President and CEO, John-Mark Staude stated: "We are excited to pick up more prospective ground in Ontario within the fertile Wawa Subprovince, which is host to many present and past producing mines in Ontario and Minnesota. Using the company's prospect generator approach, experience in the belt and industry presence, we plan to add value to the Duc Project through additional exploration and joint-venture partner-funded programs."

The Project area has excellent infrastructure, with road access from the Trans-Canada Highway and only 10km from the producing Agrium Ltd. Mine. The Project also has nearby existing power and within a 40-minute drive from the town of Kapuskasing (pop. 8,300). Interest in Ontario's critical minerals sector has attracted new explorers to this region, which in our opinion can open this area further to development for the rare earth element potential, along with the known gold endowment.

The Project is underlain by an Archean-aged metavolcanic and metasedimentary suite consisting of greywacke, arkose, and iron formation similar to the rocks known to host both the carbonatite and gold deposits. To the west and north, the terrain is underlain by east-west striking metasedimentary schists and mafic metavolcanic flows belonging to the Quetico Subprovince. The south and east areas of the Project are underlain by hornblende-quartz feldspar gneiss and granite bodies belonging to the Wawa Subprovince. The Project also lies within the LePage Fault System. This system is part of the western margin of the KSZ and consists of a series of parallel northeast trending fault structures, which include the Rufus Lake and Opasatika Lake faults. Both faults cross the property and are easily identifiable on the regional government airborne magnetic survey sheets. Given the structural feeders and tectonic evolution the Company sees high prospectivity for discoveries of potential large bodies associated with dynamic tectonic- magmatic evolution.

The next phase of proposed exploration includes ground-based geophysics building upon previous work to further refine the larger structures likely responsible for gold mineralization in the area. Past work included sonic drilling and basal till sampling which may be needed in areas of thick cover.
