During this time, the Company has actively expanded in Canada, acquiring new projects and conducting target definition exploration work across its Canadian portfolio. These steps taken in the past six months have strengthened the Company's move beyond Mexico, which has been progressing for the past two years. Riverside anticipates numerous new Canadian catalysts in the next half-year. With a commitment to advancing its diverse portfolio of mineral assets and leveraging strategic partnerships. To that effect, Riverside has made significant progress in its exploration endeavors, diversifying its commodity mix and expanding into new jurisdictions. In the coming six months, the Company plans to expand its projects beyond precious and base metals, incorporating more critical metal assets and royalties. The key mid-year developments are outlined below:

• Ontario Canada additional projects and expansion at Pichette with high grade gold drill results.
• Geophysics exploration funded through Riverside is advancing projects to drill and partnering stage at Duc project with targets expanded in scale by more than 4X.
• Property consolidation at the high-grade Union Project in Sonora, Mexico and delivering up to 1 oz/ton Au assays in the now controlled mine area.

Continued Expansion in Ontario's Geraldton and Porcupine Mining Districts

Riverside Resources continued to expand and advance its Canadian portfolio during the first half of 2023 by acquiring additional claims at the Pichette Project west of the Hardrock Gold Mine complex of Equinox Gold near Geraldton, Ontario. The Company also acquired the Duc Project in the Porcupine Mining District of northwestern Ontario. The Duc Project, spanning over 600 hectares, is strategically positioned west of the past producing Agrium Ltd. carbonatite phosphate mine with critical metal concentrations and within the highly prospective Wawa Subprovince for Rare Earth Elements (REE) and gold deposits. Riverside's generative exploration approach using historic data, proprietary databases, and field experience, coupled with personal historic knowledge of the area, aims to unlock the full potential of the Duc Project through additional exploration and joint-venture partnerships. The presence of rare earth element occurrences and orogenic gold deposits within the Wawa Subprovince further enhances the prospectivity of the region as Riverside continues the strategy of generating and owning quality projects in Canada.

Completing a Helicopter Magnetics Survey in Northwestern Ontario

Riverside Resources completed an airborne geophysical helicopter magnetics survey on the Duc Project in northwestern Ontario, which provided greater context for existing data Riverside already defined multi-kilometer structural target prospective for gold and REE -critical metals that can now be progressed during the second half of 2023. This survey employed SHA Geophysics' Heli-3G technology, offering cost-effective and high-quality results. The magnetic data interpretation revealed two major parallel shears that traverse the central part of the Duc Project, providing important geological boundary information and identifying direct structural zones which are consistent with the style of feature that hosts major gold deposits.

Union District, Sonora, Mexico Consolidation and Advancement

In a strategic move to consolidate the Union Project area, Riverside Resources signed an Option Agreement to acquire the past-producing Union Mine, situated within the Union District of Sonora, Mexico. This district boasts a rich history of high-grade zinc, gold, and silver production from carbonate replacement mines. By securing a 100% undivided right, title, and interest in the Union Mine, Riverside expands its district wide mineral concession coverage and a foothold in the region and establishes a clear path towards advancing exploration targets within this prospective land package.
