A rock-chip sample from a breccia outcrop has assayed 10% copper with 131 grams per ton (g/t) silver at the Tsenken A target area, the company said in a statement on Tuesday.

Tsenken A lies around 2 kilometres from the Tsenken N1 target, where grades of up to 7% copper with 55 grams per ton (g/t) silver were found in boulders protruding from beneath the jungle floor, as reported by the group last week.
The firm has said that the Tsenken N1 target is likely cylindrical in shape and will be readied for scout drilling soon as possible behind the drilling that is planned for the Tsenken N2 and N3 targets.
On July 16, Aurania also noted that there was a common geological theme in the area - copper-silver in breccia, sedimentary-hosted mineralization, and also in intrusive rocks.
Today, Dr Keith Barron, Aurania's chairman and CEO, pointed out that sedimentary hosted copper-silver had not previously been found near to porphyries in any of the recognized international copper camps.
"Our project is clearly something different and potentially important, but the relationship to porphyry and the geometry will ultimately be determined by drilling, which we intend to initiate in the 3rd quarter of this year," he told investors in the statement.
"Sedimentary-hosted copper-silver has been found regionally within the Aurania concessions over an extent of 23 kilometres and is almost always associated with carbon-bearing shales and sandstones full of plant fossils," he added.
Aurania's exploration teams re-entered the field in mid-June this year and the firm is complying with the government-imposed coronavirus (COVID) restrictions that require a maximum 50% capacity in the field office at any one time.
The Lost Cities-Cutucu asset lies in the eastern foothills of the Andes mountain range of southeastern Ecuador.
Teams are working in six target areas including Tsenken N3, Tsenken N4, Tiria, Kirus, Awacha and Crunchy Hill. Crews are also working to establish a remote camp from which scout drilling at Tsenken N2 and N3 is planned.
