Medaro Mining completes geophysical survey at Clay Howells West

Vancouver, British Columbia--(Newsfile Corp. - July 27, 2026) - Medaro Mining Corp. (CSE: MEDA) (OTCID: MEDAF) (FSE: 1ZY) ("Medaro" or the "Company") is pleased to announce the completion of its 2026 airborne geophysical survey and Phase 1 ground exploration program at the Company's Clay Howells West Rare Earth Element ("REE") Project, located 50 kilometres north-northeast of Kapuskasing, Ontario. The exploration program integrated high-resolution helicopter-borne magnetic, very low frequency electromagnetic ("VLF-EM"), and radiometric surveys with systematic geological mapping, prospecting, ground radiometric surveys, and rock and soil geochemical sampling. The combined datasets will be used to refine exploration targets and prioritize areas for follow-up exploration.

Airborne Survey Successfully Completed The Company has received the final report from Geo Data Solutions GDS Inc. for the airborne geophysical survey conducted over the Clay Howells East and Clay Howells West claim blocks. Survey highlights include: Completion of 1,143 line-kilometres of helicopter-borne magnetic, VLF-EM and radiometric surveying over the two project blocks. Acquisition of magnetic, VLF-EM and radiometric datasets to support structural interpretation.

Survey coverage completed at 50-metre traverse line spacing with 350-metre tie lines, providing detailed geophysical coverage. Average helicopter terrain clearance of approximately 36 metres to support enhanced data resolution. Acquisition of magnetic, VLF-EM and radiometric datasets to support structural interpretation, geological l mapping and the identification of radiometric anomalies.

Processing of the datasets, including residual magnetic intensity, first vertical derivative, VLF-EM conductivity products, and potassium, uranium and thorium radiometric maps, which will be integrated with geological and geochemical information to assist in generating and prioritizing areas for follow-up exploration, including potential drill targets.

Collected a total of 61 rock samples and 45 soil samples from multiple areas of the property.

All samples have been submitted to Activation Laboratories Ltd. ("ActLabs") in Timmins, Ontario, for multi-element geochemical analysis, including rare earth elements. Completed ground verification of historical radiometric anomalies using a Super-Spec RS-125 handheld gamma-ray spectrometer. Scintillometer readings from rock samples generally ranged between 120 and 200 counts per second ("cps").

Several rock samples recorded elevated readings between 200 and 325 cps, while one sample recorded locally elevated readings ranging from 750 to 950 cps. Scintillometer measurements represent preliminary field observations only and are not direct measurements of uranium, thorium, rare earth element concentrations or economic mineralization. Laboratory analytical results are required to determine elemental concentrations.

Rock sampling focused primarily on syenite outcrops, pegmatites and related intrusive rocks, while soil sampling was completed over interpreted geophysical targets. Ground access was achieved using ATVs and an Argo all-terrain vehicle, with helicopter support utilized for one day to access areas inaccessible by existing roads or trails.

"The high-resolution airborne datasets, combined with geological observations, ground radiometric measurements and geochemical sampling, provide an integrated exploration dataset that will assist in refining exploration targets and planning for the next phase of work, including evaluating the potential for an initial drill program. We look forward to receiving the analytical results from ActLabs and final processed airborne dataset as we continue to advance the Project. The Project remains at an early stage of exploration, and no Mineral Resources have been defined." Quality Assurance and Quality Control (QA/QC) Rock samples were collected from representative outcrops based on lithology, alteration, mineralization and structural features.

Soil samples were collected from the B-horizon where possible using standard industry procedures. Samples were placed in sealed sample bags, transported under chain of custody by Company personnel and submitted to ActLabs in Timmins, Ontario, an ISO/IEC 17025 accredited laboratory, for multi-element analysis including rare earth elements. Analytical results are pending.

About the Clay Howells West Project The Clay Howells West Project is located in northern Ontario, approximately 50 kilometres north-northeast of Kapuskasing, within the Clay-Howells alkalic intrusive/carbonatite complex. The project is situated in an area characterized by syenites, carbonatites, massive magnetites, fault-altered breccias and syenite breccias. Historical regional datasets indicate magnetic and radiometric anomalies.

Historical exploration in the area can be traced back to the 1950s and was largely focused on magnetic anomalies and nearby occurrences. The Company cautions that the Project is at an early stage of exploration. References to nearby deposits, historical exploration, regional geology or adjacent mineralization are provided for geological context only and are not necessarily indicative of the mineralization on the Project.
