The second hole drilled at the Lana Corina project in Chile by Culpeo Minerals (ASX: CPO) hit what the company describes as consistent visible sulphide copper mineralisation over a 400m length.
The current drill program is aimed at confirming the presence of near surface breccia pipes with copper mineralisation, and which pipes are part of a vertically extensive copper porphyry system.
Meanwhile, sampling of the first hole is now complete and assay results from that are extended three weeks from now.
First two drill holes intersected copper sulphide
Managing director Max Tuesley said Culpeo’s maiden drilling program at Lana Corina is testing the continuity of mineralisation at depth, and to verify historic assay results.
“We are now two holes into the nine-hole program and visual results are extremely encouraging, with both drill holes intersecting significant copper sulphide mineralisation,” he noted.
The recently acquired the Lana Corina project is situated in the Coquimbo region of Chile where, the company states, near surface breccia hosted high-grade copper mineralisation offers walk-up drilling targets and early resource definition potential.
Lana Corina hosts multiple outcropping copper bearing breccia pipes associated with a well-mineralised porphyry intrusive. A drilling program has commenced immediately targeting near surface copper mineralisation and extensions to the south.
The high-grade breccia pipes identified to date outcrop at surface and extend to a vertical depth of over 200m at which point porphyry hosted, stockwork and sheeted vein style mineralisation extends deeper.
Ground-based survey begins this week
A ground-based magnetic survey covering 3.8sq km over the Lana Corina project is scheduled to begin this week.
The geophysical data will be collected over 150-line kilometres and will be undertaken on 25m line spacing.
The survey will enable Culpeo Minerals to map the alteration zone peripheral to the known mineralisation at Lana Corina with the aim of improving drill hole planning for its exploration program at the project.
Specifically, it is expected that data generated from the survey will help detect and define targets related to potential mineralisation, alteration, lithology, and structures within the Lana Corina project footprint.
Lana Corina is located in the coastal belt, Coquimbo region of Chile, approximately 350km north of Santiago. The village of Soruco is 2km north of the site and the town of Combarbala is 18km to the south.
