Riverside Resources won the right to stake the Ariel project through the claims lottery process and subsequently staked and acquired the project in northern Sonora, Mexico.

The Ariel Project is strategically located 30 km ESE of the world-class La Caridad Cu-Mo porphyry mine (1,800 Mt @ 0.45% Cu, 0.02% Mo), and 24 km SE of the Los Alisos Cu porphyry prospect. To the best of RRI’s knowledge, the area has not been drill tested previously and represents a new grass-roots target.

The Ariel property was staked by Riverside in late 2015 and developed out of a strong reconnaissance prospecting program in the area. Access to the Property is good with 30 km on dirt roads from paved highways where power grid and other infrastructure are in place servicing the nearby La Caridad mine.



This project is strategically located in the Laramide copper belt of northern Mexico and is currently at an early stage of exploration with an exploration program planned for 2016. Preliminary geologic mapping, alteration analysis and sampling has so far been conducted on the project to help focus targeting for the upcoming exploration program.



Initial observations and interpretations suggested Laramide age volcanic and intrusive host rocks and alteration patterns consistent with a copper porphyry type system. Further analysis has determined that the Ariel Project has epithermal alteration zones typical of other gold-silver districts in Sonora, with the main zone at Ariel possibly distal to a porphyry copper target. The project covers an extensive zone of hydrothermal alteration, measuring 2.8 km in length by up to 1.9 km wide in one central area and other lateral zones. These alteration types recognized on the Property are consistent with the upper parts of a porphyry Cu system.

This work corresponds to mine activity in this area looking for Turquoise and Malachite such as Cananea, El Alacran, La Caridad, and Maria, where mineralization associated with Turquoise was discovered in proximity to the deposits.

Riverside Owned Projects

Cecilia Gold Project


Riverside has acquired the option to earn 100% of two large mining concessions, creating the consolidated Cecilia gold project. The project’s concessions were previously owned by Gunpoint and Millrock Resources. The project is a low-sulphidation epithermal gold-silver project and has seen significant exploration including drilling by past owners.

Tajitos Gold Project

The 61 km² Tajitos Gold Project is located in the heart of the Sonora-Mojave Megashear Gold Belt. The Project was acquired by Riverside from a private owner and is owned 100% with no underlying royalties. Since acquiring the property, Riverside has completed multiple surface and underground sampling and mapping programs and has staked additional ground (Tejo & Cortez claims) to expand the land package. Initial exploration with Centerra is expected to include further geophysics and trenching followed by a 2nd phase with drilling.

Thor Copper Project

The 128 km² Thor Project (the “Project”) was acquired as part of Riverside’s strategic alliance with Antofagasta Minerals PLC for generative exploration throughout the southern extension of the Laramide Copper Belt in Northwest, Mexico. Thor was nominated as a Designated Project (“DP”) (see press release April 13, 2015), and as per the agreement, Riverside’s alliance partner will have the opportunity to earn a 65% interest in the project by spending $5,000,000 in exploration over the next four years.
