Exploration Highlights:
CANADA
- Deer Park Gold Project: Ongoing exploration has delivered strong sampling results and geological features similar to the historic Rossland Mining Camp, one of BC's largest historical gold producers, supporting further target development.
- Revel Project: the project's carbonatite-style REE system extends over 7 kilometers along strike, with varying widths, and remains unexplored by drilling. The project is part of BC's broader Rare Earth Element carbonatite belt, with extensive exposures of carbonatite mineralization.
- Taft Project: Recent fieldwork confirmed rare earth and gold mineralization, with good infrastructure supporting exploration resumption in early spring.
MEXICO
- Cuarentas Gold Project: Four priority drill targets identified using geochemistry, geophysics, and mapping; drill-permitted with a history of high-grade mining and strong structural corridors.
- Ariel Copper Project: Targeting a large, undrilled porphyry copper system with lithocaps, breccia pipes, and alteration zones; surface indicators suggest deeper copper potential.
- Union Gold-Copper Project: Hosts high-grade carbonate replacement deposits (CRDs) with potential for a deeper porphyry system, similar to Arizona's Hermosa-Taylor deposit.
- Additional Projects & Partnerships: Advancing Suaqui Verde (under option to Southern Empire) and Suaqui Grande (100% owned); maintaining a strong royalty portfolio.
"We are excited to see our projects advancing, both through partnerships and our own exploration efforts," commented John-Mark Staude, CEO of Riverside Resources. "As we attend PDAC in Toronto, we look forward to meeting with industry peers and showcasing our portfolio of gold, copper, silver and rare earth projects. Riverside holds royalties on several assets and also owns 100% of drill-permitted projects that are ready for turnkey exploration with existing and potential new partners. Additionally, we're pleased with the progress of our proposed transaction, with Blue Jay Gold shares expected to spin out to Riverside shareholders in the first half of 2025. Alongside this, we anticipate strong exploration and discovery potential at Cecilia and other partner-backed projects in the coming months."
Royalties
Fresnillo PLC continues drilling and resource refinement at the Tajitos project, evaluating its potential for future mine development. The newly elected President of Mexico, Claudia Sheinbaum, has expressed support for mining development, which could positively impact the progress of major projects like Tajitos Gold Project.
The Tajitos project is strategically located in northwest Sonora, Mexico, benefiting from excellent road infrastructure and access to power. The terrain is relatively flat, with no residential settlements on-site. Additionally, private ranch land where the project is located has been acquired and consolidated by Fresnillo, further facilitating potential mine construction and operations. Riverside holds a 2% net smelter royalty (NSR) on a portion of the Tajitos project, providing a strong future revenue opportunity for Riverside.
Riverside also holds a 2% NSR on the Sugarloaf Peak gold project, operated by Arizona Metals, as well as a diverse portfolio of additional royalties. More details on Riverside's royalty assets can be found on the company's website at www.rivres.com.
PDAC 2025
The Riverside team is pleased to invite investors, industry professionals, and stakeholders to visit us at PDAC 2025 in Toronto. Riverside's President and CEO, John-Mark Staude, along with key team members, will be available at booth #2413A on Sunday, March 2, and Monday, March 3, from 10 AM to 5 PM or contact us at the information below.
This event provides an excellent opportunity to connect with the Riverside team, gain insights into the company's exploration and development plans for 2025, and discuss the latest progress across our gold, copper, and silver projects in Mexico and Canada.
Additionally, Geordie Mark, CEO of Blue Jay Gold, will be attending PDAC. Blue Jay Gold, Riverside's latest spinout, represents a compelling growth opportunity, and this will be a great chance to meet with Geordie and learn more about the company's strategy and outlook.
Canada
Riverside continues to advance exploration at its Deer Park gold project in British Columbia, where recent fieldwork has provided strong sampling results, positive geological indicators, and structural features similar to those found in the Rossland Camp, one of BC's largest historical gold producers. With high-grade, multi-element ores and well-developed infrastructure, Rossland has demonstrated significant mineral potential, and Riverside has outlined compelling targets for further exploration.
For Rare Earth Elements (REEs), Riverside has made notable progress at its Revel and Taft projects. At Revel, the carbonatite-style system extends over 7 kilometers along strike, with varying widths, and remains unexplored by drilling. The project is part of BC's broader REE carbonatite belt, with extensive exposures of carbonatite mineralization. Additionally, Mount Grace, a district-scale carbonatite project staked and advanced by Riverside, has been previously studied by the British Columbia Geological Survey for its rare earth content and is now progressing with further exploration at Revel.
At the Taft Project, fieldwork conducted over the past summer included sampling and mapping, identifying both rare earth elements and gold mineralization. Taft is well-located near Salmon Arm, BC, with good road access and lower-elevation terrain, making it well-positioned for the resumption of exploration activities in early spring.
Mexico
Riverside continues to advance exploration across its gold and copper portfolio in Mexico, with significant progress at the Cuarentas, Ariel, and Union projects, among others.
At Cuarentas, the company has identified four priority target areas for drill testing. The project is drill-permitted and located on private ranch land, providing a clear path for further exploration and potentially rapid development including the existence of past mine and mill operations. With a history of high-grade mining and well-defined structural corridors, Cuarentas presents a strong opportunity for resource expansion. Riverside has made significant progress in target definition, using geochemistry, geophysics, remote sensing and geological mapping to refine drill targets.
At Ariel, Riverside is targeting a porphyry copper system characterized by large lithocaps, extensive alteration zones, breccia pipes, and veining-all indicators of a strong, undrilled porphyry copper discovery. Previous work has included mapping and geochemical sampling, particularly around former turquoise mining operations, which serve as surface indicators of deeper copper mineralization.
At the Union project in Sonora, Riverside controls three major mining areas within a large landholding. The project hosts high-grade gold potential in carbonate replacement deposits (CRDs), similar to those found in the Hermosa-Taylor deposit in Arizona, which South32 is actively developing. Union shares the same Paleozoic limestone host rocks, with an alteration halo of manganese, gold, and base metals suggesting the potential presence of a deeper porphyry copper system. CRD-style deposits in the region have historically led to significant copper discoveries, and Union remains a high-priority target for future exploration campaigns.
Other projects in Riverside's portfolio include the Suaqui Verde project, which is currently under option to Southern Empire, and the neighboring Suaqui Grande copper project, which Riverside retains 100% ownership of. The company remains well-positioned, advancing its key assets while maintaining a strong royalty portfolio through option agreements.
Exploration efforts for H1 2025 continue across multiple projects, with further results expected from Cecilia and other key targets. Riverside also remains actively engaged in joint venture discussions, welcoming potential partnerships to advance its exploration programs. The company will be attending PDAC in Toronto, where it will be available for meetings and discussions. Further details on Riverside's projects can be found on its website at www.rivres.com.
