Mining activity across North America is intensifying as exploration programs expand across Mexico, Arizona, and Canada. Emperor Metals recently provided an update on its 2026 campaign at the Duquesne West Gold Project, featuring 15,000 meters of new drilling and the resampling of 8,000 meters of historical core to bolster its geological model. This follows Kingman Minerals completing Phase III drilling in Arizona and Tier One Silver reporting high-grade results of 1,015 g/t silver at its Curibaya project. Additionally, Mercado Minerals and ATERRA Metals continue to advance their respective programs, alongside new exploration launches by Kingsmen Resources and Silver Dollar. These combined developments underscore a robust regional environment, with market participants closely monitoring upcoming assay results to influence project valuations.
