BIG TREE ANNOUNCES COMPLETION OF DRONE-MAG SURVEY AT RICHARDSON LAKE GOLD PROPERTY

A UAV (unmanned aerial vehicle) magnetometry survey of Big Tree Carbon Inc.'s Richardson Lake gold property has been successfully completed.

The company had contracted Pioneer Exploration Consultants Ltd. of Ottawa, Ont., Canada, to perform the survey over the entirety of Big Tree's 52 single-cell mining claims, which total 891 hectares. The survey area consisted of approximately 228 line kilometres of airborne data collected at 50-metre-spaced flight lines and 500-metre-spaced, perpendicular tie lines. For this survey, flight lines were flown at an azimuth of 000 degrees to 180 degrees (that is, north-south orientation). Pioneer utilized the Blackstone Hercules X4 Drone platform, utilizing the airborne Gem Systems Canada GSMP-35U potassium vapour magnetometer and paired with a GSM-19 Overhauser magnetometer base station used to diurnally correct the aeromagnetic data. The field crew mobilized to Richardson Lake on Nov. 6, 2026, completed the survey on Nov. 9, 2026, and demobilized from the Richardson Lake project site on Nov. 10, 2026.

Pioneer anticipates completion of project deliverables within five to six weeks of survey completion. Big Tree will advise shareholders and the market of program results in a subsequent news release.
