Altamira granted extension to Porta Aberta claim where recent sampling returns values up to 242.8g/t gold on surface, Brazil
Vancouver, British Columbia--(Newsfile Corp. - October 31, 2018) - Altamira Gold Corp. (TSXV: ALTA) (FSE: T6UP) (OTC Pink: EQTRF), ("Altamira" or the "Company") is pleased to announce that it has been granted a 2 year extension to the Porta Aberta claim block which is located 13km SSW of Altamira's flagship Cajueiro project (Figure 1) located in the north of the Alta Floresta Belt, in the state of Mato Grosso, Brazil.

Highlights are as follows: -
- The Porta Aberta claim blocks amounting to 1,521ha and located 13km SSW of the Cajueiro project area have been extended for a further two years
- Recent reconnaissance work by Altamira suggests the presence of a series of high-grade veins with gold values ranging from 0.5g/t - 242.8g/t gold from a total of 12 surface rock samples taken within a NNW trending shear zone over a distance of approximately 2.5km
- Three of twelve samples returned values of 199.3g/t, 202.1g/t and 242.8g/t gold from poorly exposed NE trending veins within weathered granitic rocks over a distance of 800m (Figure 2 - The Porta Aberta project showing historic placer workings and location of surface samples with gold values.)

The Porta Aberta project area is characterized by extensive historic placer workings which produced an estimated 500kg of gold and cover an area of several square kilometers. Outcropping gold mineralization appears to be confined to a series of quartz-sulphide veins within a NNWtrending shear zone characterized by silica-sericite-pyrite alteration which has been traced for 2.5km and is open to the north and south. The width of the shear zone and the width and extent of individual veins within the zone is, as yet, unknown.
Reconnaissance rock chip sampling from outcropping quartz-sulphide veins returned gold values ranging from 0.5 to 242.8g/t gold (12 samples) with three samples returning 199.3g/t, 202.1g/t and 242.8g/t gold. In addition to the high-grade gold values returned from the surface sampling, elevated Ag (up to 60g/t), Zn (up to 0.13%), Pb (up to 1%) Cu (up to 0.08%) values were also returned.
Commenting on these results, Mike Bennett, President & CEO stated "the discovery of very high-grade gold mineralization at Porta Aberta which is located just 13km SSW of our flagship Cajueiro project, is highly significant and comes on top of recent discoveries at Matrincha and Baldo East at Cajuiero. We are optimistic that additional surface work at Porta Aberta will allow us to define targets ahead of drilling".
