Altamira Gold intersects new gold zone within second porphyry at Morro Verde

Altamira Gold reports a new high-grade gold intercept within a second porphyry body at the Morro Verde target in Brazil’s Cajueiro District, strengthening the 6.5 km mineralised corridor and confirming the project’s district-scale potential.

Altamira Gold (TSX-V: ALTA) has announced a significant exploration breakthrough after drilling revealed a new zone of gold mineralisation within a second porphyry body at the Morro Verde target in the Cajueiro District of Mato Grosso, Brazil. The discovery was made during reconnaissance drilling over a gold-in-soil anomaly accompanied by broad sericite alteration.

The mineralised interval is associated with an altered quartz porphyry intrusion, showing geological similarities to both the Maria Bonita deposit and the recently identified Tavares Norte prospect, located 1.5 kilometres west of Morro Verde.

High-grade intercepts support the economic potential of the system

Drillhole MRV003 returned a promising intercept of:

• 8 metres @ 3.5 g/t gold from 176 metres, including
• 1 metre @ 15.4 g/t gold

Altamira stated that this result indicates the potential for higher-grade mineralisation within the Morro Verde porphyry.

CEO Mike Bennett highlighted the broader significance of the discovery:

“Scout drilling has now intersected mineralised intrusives at the first two of our eight district targets. The grade in the Morro Verde intercept is particularly encouraging as it confirms the potential to find mineralisation with a combination of grades and widths that could have economic potential for both open-pit and underground mining operations.”

Bennett added that Altamira now has drill intercepts in two separate gold-mineralised porphyry intrusives spaced over a 6.5-kilometre east-west corridor, reinforcing the district-scale nature of the system.

Two drill rigs advancing exploration across the Cajueiro District

Altamira currently has two drill rigs operating at Cajueiro:

• One rig is expanding the Maria Bonita and Central resources.
• The second rig is targeting extensions of known gold-bearing structures and completing infill drilling to support resource development.

Additional drilling is planned at both Morro Verde and Tavares Norte to further delineate the porphyry systems and test continuity of mineralised zones identified in MRV003 and TVN002.

Cajueiro remains one of Altamira’s most advanced projects in Brazil

Located 75 kilometres northwest of Alta Floresta, the Cajueiro District benefits from road access, grid power and a local water supply. It is considered Altamira’s most advanced gold project.

The Maria Bonita open-pit resource currently comprises:

• Indicated: 24.19 Mt @ 0.46 g/t gold (357,800 oz)
• Inferred: 25.64 Mt @ 0.44 g/t gold (362,400 oz)

Maria Bonita forms part of a district-scale system interpreted to share a common geological origin, marked by a 15-kilometre belt of historical alluvial gold workings along the Teles Pires River.

Altamira believes a substantial portion of this gold originates from an 8-kilometre east-west corridor of soil and rock-chip anomalies aligned with sub-cropping intrusions. This suggests the presence of a long-lived, deep-seated crustal structure highly prospective for multiple porphyry bodies.
