Vancouver, BC: Riverside Resources Inc. ("Riverside" or the "Company") (TSX-V: RRI) is pleased to announce that the Company has staked and is in the process of acquiring title to the Compuerta Copper Project (the “Project”) in Sonora, Mexico. The Project will now be advanced under the terms of the Company’s copper porphyry exploration alliance (the “Alliance”) with a wholly owned subsidiary of Antofagasta plc. (“Antofagasta”). The Project is located 6 km south of the Washington Cu-Mo deposit and 75 km SW of the La Caridad Cu-Mo Mine, part of the most productive portion of the NW Mexico Laramide Copper Belt. Early results from initial rock chip sampling conducted by Riverside have returned up to 0.7% copper (Cu) from outcrops and the Company has received initial approvals from Antofagasta for additional funding to carry out further exploration and target definition at Compuerta, subject to execution of an earn-in and option agreement.

Exploration plans are anticipated to include further geological mapping and geochemistry, with an airborne geophysical survey and proof-of-concept drilling as potential next steps. As per the Alliance terms, Antofagasta will have the opportunity to earn a 65% interest in the Compuerta Project by completing $5,000,000 in exploration over the next four (4) years (see news release July 22, 2013). 

Riverside’s President and CEO, John-Mark Staude, commented: “We are very pleased with the progress within both of our strategic alliances with Antofagasta, and look forward to exploration results in northwest Mexico at Compuerta and in British Columbia, Canada at Swift Katie in the months ahead.”

Property Details:

The 200 km2 Compuerta Project is located 6 km south of the high grade Washington Cu-Mo deposit (1.2Mt @ 1.8% Cu, 0.106% Mo)[1] in the Cumobabi District of north central Sonora. This District is positioned close to the productive Laramide Copper Belt, with the La Caridad Mine (1200Mt @ 0.6 % Cu)[2] located 75 km to the NE. 

Riverside staked the Compuerta property based on successful generative efforts and follow-up field surveys, which identified Laramide age intrusive rocks with previously unrecorded copper mineralization and zoned alteration consistent with a Cu porphyry system. These surface expressions of a system are located at the edge of cover and aeromagnetic data and alteration zoning suggest the target extends under cover to the west. Riverside has collected rock chip and stream-sediment samples during follow up visits which now confirm visual indications of a copper system with multiple samples returning greater than 0.1% Cu and up to 0.7% Cu.
