The assays were the first from a 2000 metre (m) programme to confirm a breccia pipe style deposit at the Peruvian prospect.
Glen Parsons, Mariana’s chief executive, said: "These high grade copper and gold results for the twin hole at Breccia pipe 1 are extremely encouraging in terms of the system's potential and our confidence has certainly increased as we move forward.
The new hole was twinned with an earlier drilled in 1996 by previous licence owner Rio Amarillo.
Drilling intersected widespread breccia-hosted sulphide mineralisation including 21m at 1.5% copper, 4.7 grams per tonne (g/t) gold, 34 g/t silver from 59m down. This is addition to the strong intersections reported in the historic hole.
High level porphyry style alteration and mineralisation was also intersected in the second and third holes of the programme at the northern Cima Blanca target area, with assays pending Mariana said.
Parsons added its exploration model was based on the possibility of there being a large mineralised porphyry system at depth at Soledad.
“We are now targeting untested areas away from Breccia 1,“ he added, though drilling has been halted by recent poor weather though is expected to resume soon.
Mariana has an option to earn a 70% interest in Soledad, which is fully drill-permitted, through its agreement with tenement owners Condor Resources.
