Vancouver, British Columbia--(Newsfile Corp. - April 21, 2020) - Riverside Resources Inc. (TSXV: RRI) (OTCQB: RVSDF) (FSE: R99)("Riverside" or the "Company"), is pleased to report results from its recent rock-chip sampling and target mapping program at the Los Cuarentas Gold Project (the "Project") in Sonora, Mexico. Riverside collected additional channel samples along the primary targets and developed a better understanding of the structural setting identifying two additional vein systems and finding surface exposures with high-grade gold. The Los Cuarentas Project is located 17 km northwest of SilverCrest's high-grade Las Chispas deposit and 15 km northeast from Premier Gold Mines, Mercedes gold mining operation. The new sampling results increase the Company's confidence in the potential for its 100% owned Los Cuarentas Project to host a near-surface, high-grade gold vein system. Drill permits have now been granted.

Key Highlights:
•High-grade gold samples including: 18 g/t, 12.3 g/t, 7.3 g/t, and 3.0 g/t Au
•Total of three (3) well-defined drill-ready targets
•Identification of three (3) new prospective structures: El Sombrerito, El Sombrero Norte and Santa Rosalia Norte
•Approximately 30% of 31 samples returned anomalous gold (>0.2 g/t Au)
•Drill permit approval received from Sonoran Environmental Agency to support further exploration and drilling at the Project

Riverside's President and CEO, John-Mark Staude, stated: "We are pleased with the progress and high-grade gold results above and around the former mining operations at Santa Rosalia and other target areas. We look forward to progressing this Project potentially with a joint-venture partner and are excited to be located in between two highly valued mining and development operations. The approved drill permit allows Riverside to take the next necessary steps at Los Cuarentas."

In addition to the assay results, the Company also completed permitting for drilling and obtained local access agreements with the surface ranch owners enabling the Project to move ahead in a positive way in the coming months. The recent sampling program included 31 new rock-chip samples and Riverside geologists took the opportunity to update and create a new geological map. The new assay results show continuity along the principal mineralized zones and included five high-grades gold samples (see Table 1 below).

Sample ID Au (g/t) Target Zone Sample Type Rock Type
RRI-6023 18.00 Santa Rosalia rock chip vein
RRI-6010 12.30 Santa Rosalia Sur float vein/breccia
RRI-6014 7.19 Santa Rosalia Sur rock chip breccia/vein
RRI-6012 2.99 Santa Rosalia Sur rock chip andesite/stockwork
RRI-6019 2.29 Santa Rosalia float vein/andesite

High-grade gold mineralization at Los Cuarentas has been defined primarily along northwestern trending structural zones, which show thickening and increasing grade at structural flexures and/or structural intersections. The latest fieldwork program has also highlighted additional sub-parallel structural zones identified as splays. These splays carry some of the best historical sampling returning up to 29.7 g/t gold (see press release of January 20, 2020), leading to the definition of three additional new targets: Santa Rosalia Norte, El Sombrerito and El Sombrero Norte. Riverside's 100% owned claim block now hosts a total of 6 exploration targets (see Figure 1 below).
