Vancouver, British Columbia--(Newsfile Corp. - October 19, 2026) - Altamira Gold Corp.

Its flagship Cajueiro Gold District hosts more than 2 million ounces* of gold across two resource areas, Maria Bonita and Cajueiro Central. Maria Bonita is a large gold-bearing porphyry system with potential to host substantial gold resources.
