Altamira Gold (TSXV: ALTA) is proving that there is more to its Cajueiro District than its established deposits. The Vancouver-based explorer announced Wednesday that its first-ever scout drill hole at the Guillermo target in central-western Brazil has intersected high-grade gold, marking another win for its regional exploration strategy.
The standout result from the Guillermo prospect, located just two kilometres northeast of the company’s Cajueiro Central resource, featured an intercept of 7 metres at 4.2 g/t gold from a depth of 111.0 metres, including a 0.9 metre sub-interval at 18.1 g/t gold.
CEO Mike Bennett noted that Guillermo is the third regional prospect—joining Tavares Norte and Morro Verde—to deliver positive intercepts during initial scout drilling. “This target, located 2km to the northeast of the Cajueiro Central mineral resource, is one of several within an east-west corridor extending over 8km. Three of these prospects outside our mineral resources, have now delivered positive gold intercepts in scout drilling,” said Bennett.
The success at Guillermo bolsters the theory that a major 8-kilometre east-west corridor within the district holds untapped potential to scale the company’s existing resource base.
While Guillermo provided the latest discovery news, the company’s Maria Bonita deposit continues to show it has growth potential. Recent deep drilling at the site confirmed that mineralization extends at least 100 metres below the previous boundaries used in the June 2025 resource model. Hole MBA-034 tested the system to depths exceeding 600 metres, confirming Maria Bonita as a vertically extensive porphyry system. That hole intersected 0.3 g/t over 75 metres, as well as 0.4 g/t over 33.6 metres.

“Drill hole MBA-034 at Maria Bonita confirms that gold mineralization continues at depth and further drilling will target newly defined zones where we believe that there is potential to discover additional mineralized gold bearing porphyry bodies outside the current mineral resource footprint,” added Bennett.
Looking ahead, Altamira plans to maintain its dual-track approach: continuing scout drilling at untested anomalies in proximity to Maria Bonita while simultaneously conducting resource definition at Cajueiro Central. On-site accommodation and core facilities are also currently under construction at Maria Bonita, in an effort to support further exploration.
