Altamira Gold Corp has provided an update on its ongoing exploration program for copper and gold at the Santa Helena project in Mato Grosso State, Brazil, saying the first of four defined copper-in-soil anomalies to be surveyed with ground magnetics reveals a major regional fault trend and arcuate magnetic features, consistent with hydrothermal alteration associated with a porphyry intrusive-type setting.
The gold projects explorer and developer said the anomaly has dimensions and a style that are consistent with a porphyry geochemical footprint.
“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,” Altamira Gold CEO Mike Bennett said in a statement.
“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,” he added.
Altamira noted the 600 metre (m) by 200m core of the copper-in-soil geochemical anomaly has a coherent zone in excess of 300 parts per million (ppm) copper and a peak value of 448 ppm copper, against a background of approximately 40 ppm copper.
It added that stockwork quartz veining was exposed in a single trench excavated to date within the soil anomaly, with the copper-in-soil features having associated northeast-southwest trending gold vein occurrences on its periphery.
Altamira Gold is focused on the exploration and development of gold projects within western central Brazil.
