en.Wedoany.com Reported - Canary Gold Corp. (BRAZ:CSE; CNYGF:OTCQB; K5D:FSE) has received the latest technical insights and recommendations from Clara Maria Lamus Molina, a renowned geological engineer specializing in the assessment and sampling of alluvial gold deposits, for its Madeira River Gold Project in Rondônia, Brazil. Molina's review supports the company's assessment that the Madeira River is a promising large-scale alluvial exploration target. According to the press release, the next phase of technical development for the project will focus on rigorously verifying key parameters such as the geometry of paleochannels, gravel continuity, recoverable gold content, and volume grade.
Furthermore, as announced on June 10, recent deep drilling has penetrated mature coarse-grained sediments, including gravel and sand, within the target area, further corroborating the company's geological interpretation of the large paleochannel system associated with the Madeira River.
Canary President Mark Tommasi stated that the Madeira River exhibits several features common to alluvial gold systems, including interpreted paleochannel targets, favorable gravel horizons, and active alluvial mining activity within the broader Madeira River region. Tommasi noted that the next step is to conduct rigorous verification, and Ms. Molina's review provides the company with a clear technical pathway to test the project's potential in a systematic, auditable, and investor-meaningful manner.
The company stated that this review is a critical step in preparing for future exploration milestones for the Madeira River Project. The assessment could potentially support a mineral resource estimate compliant with National Instrument 43-101 standards, but this depends on continued exploration success and comprehensive data collection efforts, including additional drilling, representative sampling, QA/QC procedures, recovery testing, and geological modeling.
Molina's review report identified several positive indicators for the Madeira River Project. These indicators include active alluvial gold mining operations within the Madeira River system, visible free gold observed during site inspections of these mining operations, and favorable gravel horizons within the exploration target area. The geomorphological features of the region, such as alluvial plains, terraces, paleochannels, and high-energy channel environments, are consistent with the metallogenic conditions for alluvial gold deposition. Priority exploration targets have been delineated within paleochannels and coarse gravel systems.
Molina recommended sonic drilling as the preferred method for verifying these priority areas and suggested implementing recovery volume control for a reliable assessment of gold content. She also recommended implementing standardized logging procedures, particle size analysis, gold particle classification, QA/QC procedures, and a chain of custody system. Additionally, geological-volume modeling has been identified as a key step in preparation for future resource estimation.
Tommasi explained that alluvial gold systems differ from traditional hard rock deposits; they are typically evaluated based on volume, where the scale and continuity of paleochannels, thickness of favorable gravel layers, recoverable gold content, stripping ratio, processing efficiency, and throughput are all important considerations. The company's primary objectives are to define the channels, measure the gravel, verify the grade, test recovery rates, and progressively build a database.
Molina's key recommendations include the use of sonic drilling. Canary is currently advancing exploration on the Madeira River, focusing on alluvial or placer gold systems. Such systems form when gold is naturally released from source rocks and transported by water systems, eventually depositing and concentrating in environments such as coarse gravels and paleochannels.
The company stated that it is currently in the early stages of a phased alluvial gold development pathway, having identified preliminary geological indicators and priority paleochannel-type targets. The next step involves verifying various geological and operational factors, such as gravel geometry, continuity, and thickness, as well as gold grade and recovery characteristics.
A core recommendation from Molina is the use of sonic drilling within these priority areas. Sonic drilling is highly effective in alluvial environments because it enhances sample recovery, maintains the integrity of stratigraphic relationships, minimizes contamination, and allows for more precise volumetric measurements. These capabilities are crucial for alluvial gold exploration, where gold distribution is often uneven, relying on representative sampling and reliable assessment methods.
Looking ahead, Canary stated it plans to implement a series of systematic technical activities, including sonic drilling, detailed geological logging, and controlled sample processing. These efforts aim to establish a reliable geological and volumetric model for the gold deposit.
Molina also proposed a practical sample processing workflow tailored for alluvial environments, involving screening, washing, and concentrating materials through methods such as skilled panning or modern gravity concentration equipment. This process will be supervised by experienced technicians to ensure consistency and accuracy in preliminary field estimates.
Canary is also drawing lessons from some established alluvial gold systems to guide its approach, such as the Nechí system in Colombia. While Nechí is a mature operating system with an extensive drilling and production history, it provides a technical benchmark for Canary, demonstrating the level of detail and rigor required to advance an alluvial system from the exploration stage to resource definition and operational status.
The Madeira Project is located adjacent to one of the historically richest placer gold producing regions in South America. Historical data indicates that over 7 million ounces of gold have been extracted from the Madeira River system over the years. Canary Gold believes that the preserved paleochannels within its extensive land holdings may be part of the same gold-bearing river system responsible for the historical placer gold production in the region. Recent exploration developments are progressively validating the company's interpretation of these paleochannels. Ongoing drilling, sampling, and geological studies have confirmed the presence of gold, supporting the paleochannel model. As of May 2026, Canary has transitioned from conceptual geological targets to an active confirmation drilling phase, undertaking a significant 20,000-meter drilling campaign, marking a critical stage in project development.
