Anglo Australian Resources hits additional copper zones at Sandiego deposit
proactiveinvestors.com.au
Anglo Australian Resources (ASX: AAR) has reported that its copper focussed RC and diamond drilling program has achieved its objective of locating additional copper at the Sandiego deposit within the Koongie copper zinc project.
Koongie is located 25km south-west of Halls Creek in the Kimberley region of Western Australia.
Additional wide zones of supergene copper and zinc sulphides were intersected with results including:
- SRC076 - 33m @ 3.7% Cu, 128g/t Ag, 2.02g/t Au and 13m @ 1.73% Cu;
- SRC060 - 9m @ 2.1 % Cu, 3.3% Zn, 135g/t Ag, 0.18g/t Au, 0.21% Co;
- SRCD059 diamond hole intersects 25m of supergene sulphides (chalcocite and pyrite); and
- SRCD063, SRCD064 and SRCD078 intersect wide zones of chalcopyrite dominant sulphides.
In July Anglo Australian Resources completed an extensive drilling program, consisting of 3109m of RC and 1403.8m of diamond drilling, at the Koongie project.
The program was designed to enhance the potential for economic development of the Koongie Project and to advance the pre-feasibility work currently in progress.
The diamond drilling component of the program for deeper diamond drilling was completed mid July. Diamond holes have now been geologically logged and most mineralised intervals have been cut and submitted to the Genalysis Laboratory in Perth for analysis.
Assays from the diamond drilling are expected towards the end of August.
The discovery of the zone of supergene copper enrichment has led to the reassessment of previous drilling within this zone.
Examination of this core by a hand held XRF suggests that at least two historical cored holes, stored at the company's Halls Creek facility, have not been assayed over the full zone of mineralisation. These holes have now been cut and samples submitted for assay.
In addition to the copper intersections a number of zinc and lead lodes were intersected within the transition (or partially weathered) zone at higher levels than previous drilling.
These include:
- 19m @ 5.5% Zn 40g/t Ag (SRC060)
- 13m @ 2.2%Pb, 6.6% Zn, 59g/t Ag, 0.26g/t Au (SRC060)
- 38m @ 4.4% Cu, 3.4% Pb, 13.1% Zn, 80g/t Ag, 0.64g/t Au (SRC061)
- 6m @ 0.2%Cu, 8.9% Zn, 29g/t Ag (SRC062)
True intersection widths for the zinc lode intersections are 40-50% of down hole widths.
On completion of geological modeling and receipt and compilation of all assay data the resource will be re-estimated with an expectation of increased total copper content.
Seven diamond holes were drilled along the path of the proposed decline. These and other holes will be assessed for geotechnical purposes by specialist geotechnical contractor Dempers and Seymour.
