RIVERSIDE RESOURCES COMMENCES EXPLORATION PROGRAM AT THE

CECILIA GOLD PROJECT IN SONORA, MEXICO

May 9, 2017 – Vancouver, BC: Riverside Resources Inc. (“Riverside” or the “Company”)

(TSX-V: RRI), is pleased to announce that the Company has commenced a self-funded

exploration program at the Cecilia Gold Project (the “Project”) located in northeastern Sonora,

Mexico. Riverside’s exploration team is targeting epithermal gold-silver mineralization within a

felsic volcanic flow -dome setting. Multiple targets exist at different elevation levels within the

complex, with historic results indicating the presence of near surface gold mineralization.

Riverside’s first phase exploration program at the Cecilia Project will consist of extensive rock-

chip sampling to confirm the existence of zones of gold -bearing hydrothermal breccias and

quartz veinlet stockworks that had been previously identified by historic exploration work (view

Project History on the Company’s website ). Additional prospecting work will be completed at

the same time as the ‘confirmation’ rock sampling with the objective being to increase the extent

of the known zones of gold mineralization and to discover new zones.

Riverside’s President and CEO, John -Mark Staude, stated : “During March -April, our

Hermosillo-based team completed a number of tasks to initiate the 2017 Cecilia work program.

This included obtaining access a greements from owners of surface lands that cover the Project

area and setting up a temporary field camp close to the property. We now have our team in the

field sampling and mapping toward defining high-quality drill targets. Riverside is committed to

turning over prospects quickly and advancing the Company’s portfolio with a clear focus on

discovery and value creation. We look forward to a steady flow of news and results from work

programs in the weeks and months ahead.”

Priority gold target s that are being refined by Riverside’s rock sampling program are the North

Breccia Zone and the Central Zone (see Figure 1 below), both located on the north -eastern slope

of Cerro Magallanes , the prominent topographic feature formed by the volcanic flow -dome

complex at the centre of the Project area. Historical sampling of the North Breccia target showed

this zone of brecciated rhyolite as containing mineralization grading 2.19 g/t gold (Au) across

25 metres . A drill -hole that tested this zone yielded an intercept that averaged 1.41 g/t Au

across 30.0 metres, starting 4.0 metres down the hole. At the Central Zone, a linear array of gold

showings were previously sampled down the eastern slope of the peak. Historical sampling

results from the inferred easterly striking , sub -vertical structure include 33 metres averaging

1.18 g/t Au and 16 metres of 1.29 g/t Au and 40.8 g/t silver.

Gold assays and multi -element geochemical data obtained by this first -phase surface sampling

program will be compared to, and integrated with rock geochemical data that has been compiled

from the project databases completed by companies that previously explored the Cecilia mineral

system. Once the current rock sampling progr am has been completed and the analytical data

integrated into the Company’s project -wide database, the focus of work will be the construction

of a 3D model of the litho -structural setting of the flow-dome complex as well as the controls on

the epithermal m ineral system that is interpreted to be genetically linked to the volcanic

complex. This will lead to the definition of specific, high-potential drill targets.

Disclosure Note: The above-described exploration work programs and the analytical results that

were reported by previous operators on the Cecilia property are considered to be historical. The

reliability of the historical data is uncertain but is considered to be relevant by Company

management. It is the Company’s intention to verify, wherever reasonably possible, the most

significant historical data; however, there is a risk that the Company’s confirmation work or

future drill testing may produce results that substantially differ from the historical results.
