Gold-oriented Aurania Resources (TSXV: ARU) is finding as much copper as gold in the early innings of exploration at its Lost Cities-Cutucu project in southeastern Ecuador.
In January the junior explorer reported grades ranging from 0.9–9% copper from eight grab samples of rock in streams at its Tsenken-A porphyry target. Highlights included 9% copper with 185 grams silver per tonne and 7.1% copper with 19 grams silver per tonne.
The streams drain an area that has a geophysical signature on the edge of a large magnetic feature at Tsenken.
Copper mineralization at Tsenken-A has been found in a 3 by 1 km area, and the company says its exploration concept defines a porphyry body intruding a sedimentary and volcano-sedimentary sequence, with fluids from porphyry infiltrating and mineralizing the permeable sedimentary and volcano-sedimentary rocks.
