Culpeo Minerals Limited (ASX:CPO) has intersected visible copper sulphide mineralisation over 400m with diamond drillhole CMLCD002 at the Lana Corina Copper Project in Chile.
The current drill programme seeks to confirm the presence of copper mineralisation in near-surface breccia pipes which are part of a vertically extensive copper porphyry system.
Highlights
- Second hole (CMLCD002) intersects consistent visible sulphide copper mineralisation over 400m
- Sampling of first hole CMLCD001 is now complete and assay results are expected in three weeks
- Drilling is ongoing on the planned nine hole programme, totalling at least 4,000m
- Ground magnetic survey will commence this week
“Culpeo’s maiden drilling program at Lana Corina is planned to test the continuity of mineralisation at depth and to verify historic assay results,” Managing Director, Max Tuesley, said.
“We are now two holes into the nine hole programme and visual results are extremely encouraging, with both drillholes intersecting significant copper sulphide mineralisation in the form of chalcopyrite over continuous downhole intervals up to 400m. Culpeo looks forward to reporting assay results for this ongoing drilling programme.”
Lana Corina Drilling Programme
Lana Corina is located in the coastal belt, Coquimbo region of Chile, approximately 350km north of Santiago. The village of Soruco is located 2km north of the site and the town of Combarbala is 18km to the south.
Lana Corina is associated within a northeast-southwest orientated structural zone with >1,000m of strike and up to 400m wide. High grade copper mineralisation at Lana Corina is associated with three known copper bearing breccia pipes occurring in the upper levels of a large copper bearing porphyry system.
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.
Immediately after securing rights for up to 80% of the Project, Culpeo began a maiden drilling program at Lana Corina to test high-grade copper mineralisation which outcrops at surface.
The initial 4,000m diamond drilling programme comprises nine holes targeting breccia and porphyry hosted high-grade copper mineralised zones. The first hole of the programme (CMLCD001) was completed to a depth of 456m and intersected visual copper sulphide mineralisation over a downhole length of 300m.
The second hole of the programme (CMLCD002) was drilled to a depth of 534m and has visible copper sulphide mineralisation logged over a continuous downhole length of 400m (from 80m). The assays from CMLCD001 are pending, and CMLCD002 will be sampled and assays submitted in due course.
Ground Magnetic Survey
A ground-based magnetic survey covering 3.8 sq. km over the Lana Corina Project is scheduled to begin this week. The geophysical data will be collected over 150 line kms and will be undertaken on 25 metre line spacing.
The survey will enable Culpeo Minerals to effectively map the alteration zone peripheral to the known mineralisation at Lana Corina with the aim of improving drillhole planning for its exploration programme 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.
