Big Tree Announces Completion of DRONE-MAG Survey at Richardson Lake Gold Property

Big Tree Carbon Inc. (BIGT) completed a UAV magnetometry survey over its Richardson Lake gold property on November 9, 2026. The survey covered 891 hectares across 52 mining claims, collecting approximately 228 line-kilometres of airborne data at 50-metre line spacing.

Data processing and deliverables are expected within 5 to 6 weeks, with a subsequent news release detailing the results. This exploration update follows a series of August 2026 announcements addressing TSX Venture Exchange continued listing requirements (CLR), including a debt postponement agreement and planned financings to demonstrate activity and improve working capital.

Big Tree Carbon Inc. (BIGT) has completed a drone survey of its Richardson Lake property, marking an incremental operational step that demonstrates ongoing activity at the site. The announcement does not include drill results, resource estimates, or financial commitments. Instead, it serves as a procedural milestone required to satisfy exchange activity criteria and maintain the company’s listing status.

The material impact of this development is neutral, as the company continues to operate within a high-risk regulatory and financial environment. The completion of the survey alone does not alter the capital structure, resolve past compliance breaches, or guarantee future exploration success. The next material catalyst is expected to be the release of data in five to six weeks. Until that time, the stock remains driven by liquidity constraints and exchange compliance rather than exploration fundamentals.

Big Tree Carbon Inc. (BIGT) operates in Northwestern Ontario, focusing on gold exploration and carbon sequestration. Its flagship asset is the Richardson Lake Gold Property, a 1,700-hectare holding in the Red Lake Gold Camp located 100km from Evolution Mining’s Campbell mill and 10km from First Mining Gold’s Springpole deposit. Historic exploration on the property includes a non-NI 43-101 estimate of 140,000 ounces and significant drill strikes in 2012 and 2014.

The company also holds interests in Ranger Lake, Ranger East, Western Fold, Richardson North Extension, Bridget Lake, and McFaulds Lake. Bridget Lake is a joint venture with Evolution Mining. Big Tree Carbon has pursued carbon sequestration initiatives, including partnerships with Blue Source Canada and Lac Seul First Nation, but these efforts have not progressed due to modeling disputes and shifts in market sentiment.
