Riverside Expands Drilling Program at Oakes Gold Project, Ontario and Provides Update on Initial Findings

Vancouver, April 5, 2022 - Riverside Resources Inc. (TSXV: RRI) (OTCQB: RVSDF) (FSE: 5YY) ("Riverside" or the "Company") is pleased to announce that the Company has expanded its drilling program at the Oakes Project in Ontario, Canada. The Company initiated the program in March with a planned 1500 metres ("m") of drilling and has now completed 1705 m across 12 drill holes. The drill program was designed to test IP geophysical anomalies that were defined through Riverside's 2021 program and coincided with anomalous surface geochemical sampling completed by Riverside.

Drilling is now complete with logging, core cutting and sampling now underway. The Company has shipped the first three holes to ACT Labs in Thunder Bay for analysis and is expecting to have all core samples delivered to ACT Labs during April. Assay results are expected later in Q2, 2022 and will be released once reviewed and interpreted.

Observations from the core to this point is consistent with surface findings showing similar patterns of mineralization and lithologies from hole to hole along the HG Target, where the initial seven drill holes were focused (see Press Release March 3, 2022). The mineralized zone is described as a quartz-carbonate veining system characterized by disseminated to semi massive pyrite, pyrrhotite, chalcopyrite mineral assemblage (see Photo 1 below). These observations are similar to the mineralization noted in the previously completed sampling which returned anomalous values for gold.

Riverside's President and CEO, John-Mark Staude: "We are delighted with the excellent contractors and team working with Riverside on our Oakes exploration campaign, completing the program safely and finding encouraging geology and sulfide zones. These first insights from our drilling program suggest we have intersected the likely source of the geophysics and are seeing shears and stringers that look similar to mineralized areas 20 km west at the Greenstone Mine and Geraldton Mining district. Samples are being processed and will be sent to the lab. Riverside's team will be working on detailed logging of the split core and preparing the next stages for our exploration campaign."

The simplified geological interpretation from the drilling to date suggests that sulfide mineralization (and possibly gold) is associated with shearing near or at the geological boundary between gabbroic sills and Archean-aged mafic volcanics comprising flows, tuffs and pillow basalts. Intercalated sediments and volcanics are also often mineralized and will be assayed to determine if gold is present. The expanded drill program has primarily tested only one target area (HG) plus two orientation drill holes into two other targets as is shown on the Company website: Click here.
