(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.\"SAN...
