Results from an October drilling campaign by Anglo Australian Resources (ASX: AAR) at its wholly-owned Mandilla gold project near Kalgoorlie have shown a series of high-grade intercepts confirming the potential of the discovery.
Anglo said assays from 16 reverse circulation drill holes showed “outstanding and thick” intercepts with better results of 45m at 2.33 grams per tonne gold from 82m; 1m at 45.7g/t from 97m; 42m at 1.85g/t gold from 45m; 21m at 4.53g/t gold from 89m; and 1m at 48.13g/t gold.
The program was focused proximal to the Mandilla East target.
It was designed to infill the core of the historic resource area to a nominal 40m by 40m pattern and to test the zone along strike to the north.
More work will be carried out to determine the overall dip and plunge of the mineralisation and the existence of possible parallel lodes.
Broad gold zones
Anglo’s newly-appointed managing director Marc Ducler said the results continue to demonstrate the project’s broad zones of high grade mineralisation.
“These exciting [assays] provide further support for our belief that we have a substantial gold discovery on our hands at Mandilla, right on Kalgoorlie’s doorstep,” he said.
“Drilling continues to validate what appears to be a significant, large-scale gold system and our team is excited by the prospect of continuing drilling to prove how big Mandilla East can be.”
Mr Ducler said another 27 holes would be drilled to test key gold anomalies defined during the October campaign.
This will include the northern extension of the Mandilla East zone over a 400m strike length, an 800m-long southern extension of the Mandilla West zone, and moderate gold anomalism in demagnetised syenite identified to the south-east of Mandilla East.
Work to fully define the Mandilla East zone mineralisation on 40m by 40m spacing will also be carried out with the objective of substantially increasing the resource base at Mandilla East and delineating additional resources within the project.
The Mandilla project is situated in the gold and nickel rich Widgiemooltha greenstone belt in the western part of the Kalgoorlie geological domain, 60km south of the township.
The project lies on the western margin of a porphyritic granitic intrusion known as the Mandilla Syenite.
It intrudes volcanoclastic sedimentary rocks in the project area which form part of the Spargoville Group of prospects between Spargoville and Widgiemooltha.
In 2006, Anglo Australian mined the high-grade Mandilla West paleochannel, producing approximately 23,000 ounces of gold.
