Ongoing exploration by Xanadu Mines at the Kharmagtai Copper-Gold Project in southern Mongolia has confirmed three new large porphyry centres under shallow cover. Outstanding initial drill results from the program indicate a 6km-long strike potential for mineralisation.

Xanadu says the exploration is targeting the discovery of additional near-surface porphyry copper-gold deposits under shallow cover.

Detailed alteration and geochemical modelling has highlighted extensive system preservation while new gravity infill data is aiding undercover targeting.

Nineteen high-potential copper-gold and gold targets generated during a recent bedrock drilling program are currently being tested at Kharmagtai with three core rigs drilling.

Three of these targets have been now confirmed as new large porphyry centres with at least one shallow drill hole in each target returning broad zones of porphyry alteration and mineralisation.

Target 3 is a 650 metre by 550 metre porphyry target characterised by very strong copper-gold anomalism and concentric porphyry veining and alteration zoning. Two shallow drill holes have been drilled with one hole returning 44 metres from, 25 metres @ 0.19% copper and 0.27 g/t gold.

Target 4 is a large circular porphyry target of 800 metres by 750 metres characterised by very strong surface copper-gold with concentric porphyry veining and alteration zoning. Several shallow RC and DDH drill holes have been drilled at this target returning broad intercepts of porphyry-style mineralisation.

Best results are 91 metres from 30 metres @ 0.22% copper and 0.26 g/t gold; 80 metres from 31 metres @ 0.19% copper and 0.21 g/t gold; and 90.1 metres from 26.9 metres @ 0.20% copper and 0.14 g/t gold, including 8 metres from 29 metres @ 0.44% copper and 0.50 g/t gold.

Target 6 is a 1km long x 400 metre wide porphyry target characterised by anomalous surface copper-gold and zoned porphyry veining and alteration. One hole targeted the confluence of copper-gold geochemistry and a bullseye magnetic anomaly encountering gold-rich porphyry style mineralisation returning 96 metres from 95 metres @ 0.35 g/t gold and 0.10% copper. It is believed that this hole has tagged the very edge of a significant porphyry system.

Drilling continues and the remaining targets will be tested over the coming months before all targets are assessed to focus the drill rigs on the highest grade and largest systems.

Xanadu’s managing director and CEO Dr Andrew Stewart said, “The results of this systematic drill program are proving to be very exciting with three new high-priority targets returning broad zones of porphyry copper and gold mineralisation under shallow cover.

“We plan to test all 19 high-potential copper-gold and gold targets generated during a recently completed bedrock drilling program. Less than half of the footprint of the system and only six targets have been tested.

“The identification of the high-density stockwork copper-gold mineralisation in at least three of the new targets is an outstanding result.

“However, what really excites our geology team is that the mineralisation is hosted within phyllic to intermediate argillic alteration which typically occurs above and laterally to porphyry mineralisation, indicating the entire 6km-long strike of the system to the east of the Stockwork Hill and Copper Hill deposits has been down faulted and the entire mineralised porphyry system appears to be intact.”
