Medaro Mining commences fieldwork at Clay Howells West REE project

Vancouver, British Columbia--(Newsfile Corp. - June 9, 2026) - Medaro Mining Corp. (CSE: MEDA) (OTCID: MEDAF) (FSE: 1ZY) ("Medaro" or the "Company") is pleased to announce that it has commenced ground fieldwork at the Company's Clay Howells West rare earth element ("REE") project located in northern Ontario, approximately 50 kilometres north-northeast of Kapuskasing. The current field program forms part of Medaro's Phase 1 exploration program and is designed to advance the Company's geological understanding of the Project through systematic prospecting, geological mapping, radiometric surveying, and geochemical sampling. The work is intended to support target generation and prioritization for possible follow-up exploration.

The current field program is expected to include, subject to access, weather, exposure and field conditions: ground-based radiometric surveying using portable radiometric instruments, which may include a gamma-ray spectrometer or scintillometer, to measure total count radioactivity and, where instrument capability permits, potassium, uranium and thorium values; reconnaissance geological mapping and prospecting focused on lithological contacts, structural features, alteration zones and radiometric anomalies; targeted rock sampling, including grab samples and, where exposure permits, selective channel samples; soil geochemical sampling over accessible target areas and follow-up grids; and integration of geological, radiometric and geochemical data to define and rank priority exploration targets. The Phase 1 program is expected to collect approximately 50 to 100 rock samples and approximately 100 to 200 soil samples, subject to field conditions, access, exposure, and logistical considerations. Samples collected during the program will be submitted to an accredited laboratory for multi-element analysis, including rare earth elements, as appropriate.

Quality Assurance / Quality Control Medaro intends to conduct the field program under a standard quality assurance and quality control program. Field procedures are expected to include appropriate sample documentation, sample location recording, chain-of-custody protocols, and the insertion of field duplicates, as applicable. Samples will be submitted to an accredited analytical laboratory for preparation and analysis.

Analytical results will be reviewed by the Company and its Qualified Person prior to disclosure. Clay Howells West Project - Background and Opportunity The Clay Howells West Project is located in northern Ontario, approximately 50 kilometres north-northeast of Kapuskasing, within the broader Clay-Howells alkalic intrusive/carbonatite complex. The area is characterized by syenites, carbonatites, massive magnetite units, fault-altered breccias and syenite breccias.

Historical regional datasets indicate that parts of the broader complex are associated with magnetic and radiometric anomalies. Historical exploration in the area dates back to the 1950s and was largely focused on magnetic anomalies and nearby occurrences. The Company considers the Project to be prospective for rare earth element exploration; however, the Project remains at an early stage and additional work is required to evaluate its mineral potential.

Mark Ireton, Chief Executive Officer and Director of Medaro, commented: "The commencement of ground fieldwork at Clay Howells West represents an important step in advancing Medaro's understanding of the Project through a systematic and disciplined exploration approach. By integrating field radiometric surveying, geological mapping, prospecting and geochemical sampling, Medaro aims to identify and prioritize areas for potential follow-up exploration." The Company cautions that the Project is at an early stage of exploration.
