- Discovery of new high-grade gold target (Casa Branca) at Apiacas project with surface samples averaging 14.5 g/t gold
- Consistent gold mineralization confirmed at Maria Bonita discovery from surface
- Potential for expansion of mineralized system at Maria Bonita, which remains open in several directions and at depth
- Lower grade results in final two drill holes at Maria Bonita compared to previous high-grade intersections
Vancouver, British Columbia--(Newsfile Corp. - August 7, 2024) - Altamira Gold Corp. (TSXV: ALTA) (FSE: T6UP) (OTC Pink: EQTRF) ("Altamira" or the "Company") is pleased to update on ongoing exploration activities at the Cajueiro and Apiacas projects.
Highlights:
- Results of the final two second-round diamond drillholes at the Maria Bonita discovery located within the Cajueiro project area were received and returned 32.7m @ 0.53 g/t gold in MBA030 and 46.5m @ 0.50 g/t gold in MBA031. Work continues on the analysis and interpretation of drill results.
- Recent surface sampling at the Casa Branca target area of the Apiacas project, returned highly anomalous gold in all surface samples collected. Ten grab samples all contain gold greater than 0.5g/t, and average 14.5 g/t gold with two high grade values of 69g/t and 52 g/t gold.
- Mineralization at Casa Branca occurs in pervasive sericite-altered porphyritic intrusive host rocks containing clots of pyritic sulphides, similar to zones of gold mineralization at the Mutum target located 10km to the west.
CEO Mike Bennett commented, "The results of the last two drillholes at the Maria Bonita discovery confirm that the porphyry gold deposit carries consistent gold mineralization from surface. We are working through the interpretation of the three-dimensional geological model to define potential zones of extension and repetition of the mineralization for further drill testing. The mineralized system remains open in several directions and at depth. Our new Casa Branca target at the Apiacas project is again intrusive hosted with disseminated gold mineralization observed on surface. Further mapping and sampling are planned in advance of reconnaissance drilling."
CAJUEIRO PROJECT
The Cajueiro project is located approximately 75km NW of the town of Alta Floresta in the state of Mato Grosso (Figure 1) in central western Brazil and is easily accessible by road and has grid power and local water supply. Cajueiro is the most advanced of three key projects that Altamira controls in the region, the other two being Apiacas and Santa Helena (Figure 1).

The Cajueiro project has current NI 43-101 resources of 5.66Mt @ 1.02 g/t gold for a total of 185,000 oz in the Indicated Resource category and 12.66Mt @ 1.26 g/t gold for a total of 515,000 oz in the Inferred Resource category (estimated using a gold price of US
Maria Bonita Target
Maria Bonita is located 7km west of the Cajueiro mineral resource and is easily accessible by road. The current drill program is a follow-up to the initial round of discovery drillholes which include 69m @ 1g/t gold (MBA005), 50m @ 1.1 g/t gold (MBA004), 55m @ 1.0 g/t gold (MBA002), 50m @ 1.0 g/t gold (MBA001) and 45m @ 1.4 g/t gold (MBA003) (See press releases dated September 7, November 16, 2022, and January 18, 2023).
Significant results previously reported as part of the current follow-up drill program include;
- MBA029: 213m @ 0.8g/t gold from surface including 146m @ 1.0g/t from 23m
- MBA016: 90m @ 0.6g/t gold from 14m and 65m @ 0.4g/t gold from 118m
- MBA018: 105m @ 0.5g/t gold from 23m and 24m @ 0.4g/t gold from 144m
- MBA020: 72m @ 0.4 g/t gold from 59m
- MBA022: 53m @ 0.7 g/t gold from surface
Mapping and logging of drill core from the Maria Bonita second drill program is ongoing to identify the various phases of porphyry intrusion (Figure 2).

These two short vertical HQ holes were completed primarily to provide new metallurgical samples across the grade range for further heap leach testing and optimisation. The holes were completed within the central zone of the drilling area. Sample selection and testing will proceed shortly.
APIACAS PROJECT
The Apiacas project is located approximately 120km north-west of Alta Floresta and 60km west of the Cajueiro mineral resource (Figure 1). Approximately 1 million ounces of gold is inferred to have been recovered historically (since 1980) from alluvial and eluvial sources in the district, centred on Mutum. Primary gold mineralization is poorly exposed, particularly in the large areas of former alluvial workings.
Casa Branca Target
The Casa Branca target is located 10km east of the Mutum target at Apiacas (Figure 3) and, like Apiacas, it exhibits strong sericite-pyrite alteration with disseminated gold mineralization in intrusive rocks.

This is a newly defined prospect outside the main area of historic alluvial/eluvial production at Apiacas.
The host rock is a medium grained granitic intrusive rock with sericite alteration and clots of pyrite up to 5mm in diameter. Where the pyrite oxidises, the rock develops a characteristic "leopard spot" appearance (Figure 4). The alteration zone has potential to extend over a width of 100m.
Figure 4: Typical "leopard spot' alteration of pyrite clots associated with sericite alteration and gold mineralization at Casa Branca. All of the reconnaissance samples that were collected carry gold and there is no visual clue to the higher-grade samples i.e. no direct association with quartz veining or other structures.

A proprietary drone aeromagnetic survey has been completed and the data processed via consultant geophysicist Core Geophysics of Perth, Australia. The results indicate an association between the prospect location and a magnetic low lying to the north of a magnetite bearing intrusive whose contact is mappable on the ground (Figure 5).

Ten samples were collected from the alteration zone exposed on surface and all returned gold values above 0.5g/t. The samples average 14.5 g/t gold with two high grade values of 69 g/t and 52 g/t gold (Table 2). Further mapping and sampling is in progress and could lead to the definition of targets for reconnaissance drilling.
