Canary Gold Corp. (CSE: BRAZ; OTCQB: CNYGF; Frankfurt: K5D) announced it has received additional technical observations and recommendations from internationally recognized geologist-engineer Clara Maria Lamus Molina regarding its Rio Madeira alluvial gold project in Brazil. The review provides a roadmap to advance from preliminary geological observations toward systematic, representative and auditable technical data, according to the company's June 25, 2026 news release.
Ms. Molina's review highlights several positive indicators at the Madeira River Project, including active alluvial gold mining observed within the wider Madeira River system and visible free gold during inspection of active operations. The review also identifies favorable gravel intervals, geomorphological features compatible with alluvial plains and paleochannels, and recommends sonic drilling as a preferred validation tool in priority target areas.
Canary Gold believes the review represents an important step in positioning the project for future exploration milestones, including evaluation of whether sufficient technical information can ultimately support a National Instrument 43-101 compliant mineral resource estimate. The company cautions that this depends on continued exploration success, additional drilling, representative sampling, QA/QC, recovery testing and geological modeling.
Mark Tommasi, President of Canary Gold, stated: “Rio Madeira exhibits several characteristics commonly associated with alluvial gold systems, including interpreted paleochannel targets, favourable gravel horizons and active alluvial mining within the broader Madeira River region. The next step is disciplined validation. Ms. Molina's review gives us a clear technical pathway to test the project in a way that is systematic, auditable and meaningful for investors.”
Alluvial gold systems are evaluated on a volumetric basis, where the size and continuity of the paleochannel, thickness of favorable gravels, recoverable gold content, stripping ratio, processing efficiency and throughput are all important. Canary's objective is to define the channel, measure the gravel, validate the grade, test recovery and build the database step by step.
A central recommendation is the use of sonic drilling in priority target areas. Sonic drilling is considered well suited to unconsolidated alluvial environments because it can improve sample recovery, preserve stratigraphic relationships, reduce interval contamination, improve fine-material recovery and support more accurate measurement of recovered sample volume. These factors are critical in alluvial gold exploration, where gold distribution can be irregular.
Future work is expected to focus on systematic sonic drilling in priority areas, metre-by-metre geological logging, recovered-volume measurement by interval, controlled sample processing and gravity concentration, gold-particle recovery and classification, laboratory validation, robust QA/QC and chain-of-custody procedures, and geological-volumetric modeling.
Canary also reviewed mature alluvial gold systems such as the Nechí operation in Colombia, operated by Mineros S.A., which has NI 43-101 mineral resource and reserve disclosure. The company cautions that Nechí is referenced solely as an educational benchmark and no inference should be drawn that Rio Madeira hosts comparable mineralization.
The company is now reviewing budgets, logistics, access and sequencing for a priority sonic-drilling and sample-processing program. Canary cautions investors that exploration remains at an early stage and no mineral resource has been defined.
The scientific and technical information has been reviewed and approved by Andrew Lee Smith, P.Geo., a Qualified Person as defined by National Instrument 43-101. Mr. Smith is not independent as he serves as Executive Chairman of Canary Gold Corp.
Canary Gold Corp. is a Canadian public exploration company focused on gold projects in Brazil. The company holds an option to earn up to a 70% interest in the Rio Madeira Project and has expanded its land position to approximately 94,700 hectares through an acquisition from Talisman Venture Partners Ltd.
