Medaro Mining Corp. (CSE: MEDA) has successfully completed its 2026 airborne geophysical survey along with the Phase 1 ground exploration program at the Clay Howells West Rare Earth Element Project located in northern Ontario. The company combined helicopter-borne magnetic, VLF-EM, and radiometric surveys with detailed geological mapping, prospecting, and geochemical sampling across the property, situated 50 kilometres north-northeast of Kapuskasing. These exploration datasets will be utilized to refine target areas and prioritize zones for potential drilling and future exploration phases.
Key Points
- Medaro Mining Corp. (CSE: MEDA) has completed the 2026 airborne geophysical survey and Phase 1 ground exploration at Clay Howells West.
- The survey covered 1,143 line-kilometres of helicopter-borne magnetic, VLF-EM, and radiometric data collection over the claim blocks.
- Field teams gathered 61 rock samples and 45 soil samples, which were submitted to Activation Laboratories for multi-element geochemical analysis including rare earth elements.
- Several rock samples showed elevated radiometric readings between 200 and 325 counts per second, with one sample exhibiting readings between 750 and 950 cps.
- Analytical results from ActLabs and the final processed airborne datasets are pending; the project remains in early-stage exploration with no defined mineral resources.
Extensive Airborne Geophysical Survey Completed
Medaro Mining received the final report from Geo Data Solutions GDS Inc. for the airborne geophysical survey conducted over the Clay Howells East and West claim blocks. The survey employed helicopter-borne magnetic, very low frequency electromagnetic (VLF-EM), and radiometric instruments to map subsurface features and identify geological targets for rare earth element exploration.
The airborne survey encompassed 1,143 line-kilometres with an average terrain clearance of approximately 36 metres. Executed at 50-metre traverse line spacing and 350-metre tie lines, the survey provided detailed geophysical coverage over the exploration claims. Data acquisition included magnetic, VLF-EM, and radiometric datasets to support structural interpretation and detect radiometric anomalies linked to rare earth mineralization.
Data Processing and Integration Strategy
Collected datasets have been processed to produce residual magnetic intensity maps, first vertical derivative magnetic analyses, VLF-EM conductivity products, and potassium, uranium, and thorium radiometric maps. Medaro plans to integrate these geophysical results with geological observations and geochemical data from the ground exploration phase.
This integrated dataset approach aims to help Medaro generate and prioritize exploration targets for follow-up activities, including potential drill targeting. The first vertical derivative magnetic map has been released alongside this announcement to visually represent magnetic anomalies across the property.
Phase 1 Ground Exploration Sampling Outcomes
During the Phase 1 ground program, Medaro conducted systematic geological mapping, prospecting, and ground radiometric surveys over priority targets identified through earlier studies. Field crews collected 61 rock samples and 45 soil samples from multiple locations. Rock samples targeted syenite outcrops, pegmatites, and related intrusive rocks, while soil samples focused on geophysical targets from airborne data.
All samples were submitted to Activation Laboratories Ltd. (ActLabs) in Timmins, Ontario, an ISO/IEC 17025 accredited lab, for multi-element geochemical analysis including rare earth elements. Standard industry protocols and chain of custody procedures were followed to ensure data integrity. Soil samples were collected from the B-horizon when possible to enhance detection of subsurface geochemical signatures. Analytical results are pending.
Field Radiometric Measurements and Findings
Medaro personnel conducted ground verification of historical radiometric anomalies using a Super-Spec RS-125 handheld gamma-ray spectrometer. Scintillometer readings from rock samples generally ranged from 120 to 200 counts per second (cps). Several samples exhibited elevated readings between 200 and 325 cps, indicating above-background radiometric responses, with one sample recording locally elevated readings between 750 and 950 cps.
The company emphasizes that these scintillometer readings are preliminary field observations and not direct measures of uranium, thorium, rare earth element concentrations, or economic mineralization. Laboratory analyses from ActLabs will be necessary to quantify elemental concentrations and evaluate the significance of these radiometric anomalies. Handheld measurements serve as a screening tool for sample selection and field interpretation but do not replace quantitative assay data.
Geological Context and Location
The Clay Howells West Project is situated in northern Ontario, approximately 50 kilometres north-northeast of Kapuskasing, within the Clay-Howells alkalic intrusive and carbonatite complex. The property features syenites, carbonatites, massive magnetites, fault-altered breccias, and syenite breccias. Historical regional data highlight magnetic and radiometric anomalies, with exploration dating back to the 1950s focused on magnetic anomalies and nearby mineral occurrences.
Medaro notes that references to nearby deposits, historical exploration, regional geology, or adjacent mineralization provide geological context only and do not necessarily indicate mineralization on the Clay Howells West Project. The company has not verified all historical information and advises against relying on such data as confirmation of mineralization on current claims.
Access and Field Logistics
Ground access was primarily achieved using all-terrain vehicles (ATVs) and an Argo all-terrain vehicle. Helicopter support was utilized for one day during Phase 1 to reach areas inaccessible by roads or trails. This combined approach enabled the exploration team to collect samples and conduct observations over a broader property area than ground access alone would allow.
The announcement confirms successful completion of fieldwork, accompanied by photographs documenting key geological features such as syenite outcrops with elevated radiometric responses, contact relationships between rock types, and soil sampling activities.
Project Status and Next Steps
Medaro Mining confirms the project remains in early-stage exploration with no defined Mineral Resources. Mark Carruthers, President and CEO, described the completion of the airborne survey and Phase 1 field program as "an important milestone" for Clay Howells West. He highlighted that the integrated exploration dataset will aid in refining targets and planning subsequent work, including evaluating an initial drill program.
The company anticipates receiving analytical results from ActLabs and the final processed airborne dataset as the project advances. However, no timeline or details regarding scope, timing, or budget for future exploration phases, including drilling, have been provided.
Quality Control and Technical Oversight
Rock samples were collected from representative outcrops based on lithology, alteration, mineralization, and structural features. Soil samples were taken from the B-horizon where possible, following industry best practices. Samples were sealed and transported under chain of custody to ActLabs in Timmins, Ontario.
Afzaal Pirzada, P.Geo., a Company consultant and "Qualified Person" under National Instrument 43-101, reviewed and approved the scientific and technical information in this release, confirming compliance with Canadian securities regulations for mineral exploration disclosures.
