Altamira Gold Corp. (EQTRF) has filed a National Instrument 43-101 technical report for its Maria Bonita porphyry gold deposit within the Cajueiro Project in Brazil. The report, which details the maiden resource estimate originally announced on May 5, 2025, confirms the initial findings with no material differences from the previous announcement. The technical report was supervised by Qualified Person Volodymyr Myadzel, PhD, MAIG, a consultant to the company. The report is now available on SEDAR+ and the company's website for public access.

Altamira Gold (EQTRF) has announced a maiden mineral resource estimate for its Maria Bonita porphyry gold deposit within the Cajueiro Project in Brazil. The open-pit resource includes Indicated Resources of 24.19Mt @ 0.46g/t gold (357,800oz) and Inferred Resources of 25.64Mt @ 0.44g/t gold (362,400oz) at a 0.2 g/t gold cut-off grade.

A higher-grade near-surface resource using a 0.5 g/t cut-off comprises Indicated Resources of 7.56Mt @ 0.72g/t gold (176,250oz) and Inferred Resources of 5.18Mt @ 0.92g/t gold (152,940oz). The deposit remains open to the west, south, and at depth, with mineralization extending to surface and a favorable waste-to-mineralized material ratio of 0.5:1.

Maria Bonita is the first of nine porphyry-gold targets identified within the Cajueiro district. The company plans to continue drilling to expand Maria Bonita and test the eight other targets.

Altamira Gold Corp. (EQTRF) has announced new discoveries of porphyry-related gold mineralization near its Cajueiro Central Mineral Resource in Brazil. Key findings include:

A new target at Serafim, located 2km east of the existing resource, yielded a grab sample of 5.6 g/t gold. At Tavares Norte, rock samples averaged 3.2g/t gold, with a peak of 7.8 g/t gold. A 50-metre trench revealed three mineralized intervals, with 31m averaging >0.25g/t gold.

The Cajueiro project, located 75km NW of Alta Floresta, currently has NI 43-101 resources of 185,000 oz in the Indicated category (5.66Mt @ 1.02 g/t gold) and 515,000 oz in the Inferred category (12.66Mt @ 1.26 g/t gold). The project features eight new drill target areas outside the main mineralized centers, spanning an east-west distance of 14km.

Altamira Gold Corp. (EQTRF) has announced significant results from recent trenching activities at its Cajueiro Central Project. Key findings include high-grade intercepts of 6m @ 5.12 g/t gold and 4m @ 9.50 g/t gold from oxide zone metallurgical samples, plus a notable extension discovery of 17m @ 1.46g/t gold located 200 meters beyond the current Mineral Resource limit.

The project's current NI 43-101 resources stand at 185,000 oz in the Indicated category (5.66Mt @ 1.02 g/t gold) and 515,000 oz in the Inferred category (12.66Mt @ 1.26 g/t gold). The new mineralized zone extends for 350 metres from the current resource boundary, suggesting potential for significant resource expansion.

The company has completed 1,042m of trenching across 13 trenches in the Baldo and Matrincha sectors. Additionally, a 75,000 kg metallurgical sample has been collected for initial heap leach testing.

Altamira Gold (TSXV: ALTA, OTC: EQTRF) has discovered a new gold target called Guillermo within the Cajueiro district. The target, located 2.5 km north-east of the Central Resource area, revealed significant findings including:

- A rock grab sample containing 39g/t gold from altered intrusive rocks
- A second grab sample yielding 1.1 g/t gold
- Surrounding historic placer gold workings
- Soil sampling values up to 845ppb gold

The Guillermo target is the third new gold target discovered in the area, following Mombaque and Espirro. The Cajueiro project currently has NI 43-101 resources of 185,000 oz in Indicated category (5.66Mt @ 1.02 g/t gold) and 515,000 oz in Inferred category (12.66Mt @ 1.26 g/t gold).

Altamira Gold has identified a third center of hydrothermally altered and veined porphyry rocks at the Espirro target within the Cajueiro Gold District. Located 3.2km south-east of the Maria Bonita porphyry gold discovery, the Espirro target shows large blocks of float up to 50cm in size and features a magnetic low anomaly that correlates with historic placer workings. The area extends over 35 hectares, suggesting a significant primary source. This discovery follows the identification of a second intrusive porphyry system at the Mombaque target, validating Dr. Richard Sillitoe's prediction of multiple intrusive porphyry systems at Cajueiro.

Altamira Gold Corp. (TSXV: ALTA) (OTC Pink: EQTRF) has announced progress in evaluating porphyry-related gold mineralization at its Cajueiro project. Key highlights include:

• A coherent gold-in-soil anomaly measuring up to 600m by 500m has been defined at the Mombaque prospect, 1.6km east of the Maria Bonita porphyry gold discovery
• The anomaly coincides with sericite-altered volcanic tuffs and breccias, underlain by felsic intrusives similar to Maria Bonita
• Rock chip sampling revealed porphyry-style quartz veining with anomalous gold
• A coincident magnetic anomaly and altered rocks make Mombaque a compelling drill target
• The findings suggest porphyry-style gold mineralization at Cajueiro extends over a wider area than initially thought

CEO Mike Bennett stated that this development could indicate multiple porphyry gold deposits at Cajueiro, expanding beyond the Maria Bonita system where recent drilling yielded 146m @ 1 g/t gold.

Altamira Gold Corp. (TSXV: ALTA) (OTC Pink: EQTRF) has discovered new porphyry outcrops 1.6km east of the Maria Bonita discovery within the Cajueiro project in Brazil. This suggests the mineralizing system may be larger than previously thought. Key points:

1. New outcrops show highly altered and brecciated porphyritic intrusive rock with extensive sericitic alteration and quartz veining.
2. Recent drilling at Maria Bonita intersected 146m @ 1g/t gold.
3. Cajueiro project has current NI 43-101 resources of 185,000 oz Indicated and 515,000 oz Inferred.
4. Structural and geophysical studies identified several new targets within the Cajueiro - Maria Bonita area.
5. A magnetic body 2km south-east of Maria Bonita may be related to a causative porphyritic intrusive.
