September 21, 2020 – Vancouver, BC: Riverside Resources Inc. (“Riverside” or the “Company”) (TSX-V: RRI) (OTCQB: RVSDF) (FSE: R99), is pleased to provide an update on the current work program which included rock sampling and drill pad construction ahead of drilling at the Cecilia Project (the “Project”) in Sonora, Mexico. The Project is currently under option with Carlyle Commodities Corp (see press release of July 15, 2020) as both companies prepare for an upcoming drill program. Riverside is acting as the operator progressing modeling of drill targets with a key focus at the Cerro Magallanes where Riverside has identified various high-grade gold targets. The heart of Cerro Magallanes is a large, multiphase mineralized rhyolitic dome complex with four defined targets: San Jose, North Breccia, Central Target and East Target; all of which have returned high-grade samples including up to 133.7 g/t gold and 288 g/t silver (see press release of June 6, 2017). The recent work has focused on channel sampling at the San Jose and North Breccia targets with more results expected in the coming weeks.
