Altamira Gold Corp. (TSXV: ALTA) (FSE: T6UP) (OTC Pink: EQTRF), ('Altamira' or the 'Company') is pleased to provide an update on its ongoing exploration programme for copper and gold at the Santa Helena project in Mato Grosso State, Northern Brazil.

Highlights

The first of four defined copper-in-soil anomalies to be surveyed with ground magnetics at Santa Helena reveals a major regional fault trend and arcuate magnetic features, consistent with hydrothermal alteration associated with a porphyry intrusive-type setting.

The 600 x 200m core of the copper-in-soil geochemical anomaly has a coherent zone in excess of 300ppm Cu and a peak value of 448ppm Cu, against a background of 40ppm Cu. The anomaly has dimensions and a style that are consistent with a porphyry geochemical footprint. Stockwork quartz veining was exposed in a single trench excavated to date within the soil anomaly.

Previous scout drilling for gold targets 600m to the south-west of the copper anomaly showed deep weathering effects to a vertical depth of 50m, potentially leaching base metals.

The copper-in-soil features have associated NE/SW trending gold vein occurrences on their periphery. Scout drilling of these gold vein systems has identified porphyry style alteration and stockwork veining in intrusive wall-rocks to these structures. Both molybdenite and chalcopyrite have been identified in these veins.

CEO Mike Bennett commented; 'The recently completed ground magnetic survey at Santa Helena has strengthened our belief that this target has strong potential for porphyry-related copper mineralization. The prospect forms part of a regionally zoned copper and gold intrusive system and will be our first test of the copper potential in the Santa Helena area. We now have coincident geochemistry and a major structure, plus evidence of porphyry-style alteration and porphyritic intrusives in close proximity to this target, from our prior drilling. This is one of four copper-in-soil anomalies that we are testing with ground geophysics to define scout drilling targets and we look forward to drill testing these anomalies in the near future.'

SANTA HELENA PROJECT

The Santa Helena project is located immediately adjacent to the paved BR-163 federal highway in the state of Mato Grosso and 60km SW of the Jaca porphyry copper deposit which was recently discovered by Anglo American plc.

There is no history of copper production in the Santa Helena area and previous artisanal mining activity has focused on high-grade gold, hosted in vein structures.

The regional geology indicates a genetic link between the Teles-Pires intrusives and the Colider Formation volcanics, which is supported by regional scale geochemistry and geochronology with both units ranging in age from 1806-1757Ma. The Colider Fm consists of lavas and pyroclastic flows with inferred volcanic dome structures. The Teles Pires intrusives consist of alkali-feldspar granites and syenogranites and are interpreted to be the main host to porphyry-style intrusions in the Santa Helena area.

Younger (ca.1400Ma) sedimentary cover of conglomerates and arenites formerly overlay this basement. This cover, which is now reflected as remnant outliers, may have aided the preservation of porphyry alteration zones within the basement.

In a similar manner to the Jaca porphyry district (60km NE), anomalous copper occurrences have associated peripheral gold occurrences. ping, soil and rock chip sampling by Altamira has previously identified both extensions to the known vein gold targets in small scale gold workings, plus significant copper, molybdenum and gold anomalies in soils related to areas of porphyry-style alteration in a zone which extends 7km E-W by 4 km N-S, indicating the presence of a very large hydrothermal system. Pervasive 'red rock' alteration of the host intrusive rocks is found in many of the holes drilled to date.

About Altamira Gold Corp.

The Company is focused on the exploration and development of gold projects within western central Brazil. The Company holds 6 projects comprising approximately 190,000 hectares, within the prolific Juruena gold belt which historically produced an estimated 7 to 10Moz of placer gold. The Company's advanced Cajueiro project has 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 515,000oz in the Inferred Resource category.
