Limousin Project Update

Aquitaine continues to advance its 2025 drilling program along the Laurieras fault structure, building on the exploration results reported in October 2025. The Company has now completed 8,102 meters in 35 diamond drill holes, and has collected more than 10,035 samples that have been submitted for assay. Drilling has now tested approximately 1,800 meters of strike length within the mineralized corridor, extending coverage across the Laurieras, Gabillou, Pierrepinet West, Pierrepinet East, and Puits-Roux targets. This work is designed to confirm historical datasets and to evaluate extensions of ore zones both along strike and down dip from historic workings.

The Company expects to release additional drill results in January 2026, after receipt of pending assays.

ABOUT THE LIMOUSIN PROJECT

The Limousin Project is located in the historic Limousin Mining District in the Region of Nouvelle-Aquitaine, southwest France, approximately 40 kilometres south of the city of Limoges. The project currently consists of 40 square kilometres of exploration licenses, and an application for an additional 290 square kilometres is in the final stages of review by the French mining administration. In total, the project covers an area of 330 square kilometres and includes 23 past-producing gold mines that operated during the 20th and 21st centuries, as well as more than 900 ancient Gallic high-grade gold mining sites occurring along gold-bearing structures that extend for 200 kilometres of strike length.

Historical operations in the district were conducted by COGEMA, a French mining company that produced approximately one million ounces of gold between 1988 and 2002. Underground production averaged grades of 12 to 15 grams per tonne gold at a cutoff of 10 grams per tonne, with mining widths ranging from 3 to 10 metres, while open-pit production averaged 7 to 8 grams per tonne gold at a cutoff grade of 6 grams per tonne. Production and exploration records indicate that the historical data has an estimated replacement value of US$430 million.

Aquitaine's technical team has identified a number of critical accessory minerals that accompany the gold mineralization across the Limousin district, including silver, antimony, lead, copper and zinc. Results from ongoing exploration and characterization of these additional mineral endowments will be provided during 2026.
