Drilling for Xanadu Mines has confirmed that East Altan Tolgoi is a significant new discovery at the Kharmagtai Copper-Gold Project in the South Gobi region. The drilling program has returned multiple intersections of hundreds of metres grading better than 1% copper equivalent between depths of 50 metres and 700 metres from surface.
The Altan Tolgoi system now has an overall strike length of more than 800 metres and remains open to the west, east and at depth.
Xanadu has received results for two holes, one completed to a depth of 680.7 metres and the other to 704.7 metres.
The first confirms the discovery of very significant high-grade copper-gold mineralization hosted in tourmaline breccias. Within a broad zone of 390 metres from 116 metres @ 0.51% copper and 0.26 grams/tonne gold were the following high-grade intervals – 122.7 metres from 307.3 metres @ 1.03% copper and 0.56 grams/tonne gold, 46.0 metres from 384.0 metres @ 1.55% copper and 1.11 grams/tonne gold, 59.4 metres from 578.6 metres @ 0.89% copper and 1.14 grams/tonne gold, and 39.4 metres from 578.6 metres @ 1.16% copper and 1.6 grams/tonne gold.
The second hold has been assayed to a down-hole depth of 550 metres and provided further continuity of the East Altan system. Visible copper sulphide mineralization extends to 650 metres. This hole intersected 402 metres from 148 metres @ 0.4% copper and 0.36 grams/tonne gold.
Significant intervals include 28 metres from 350 metres @ 0.72% copper and 0.46 grams/tonne gold, 50 metres from 382 metres @ 0.58% copper and 0.65 grams/tonne gold, 11 metres from 450 metres @ 0.52% copper and 0.79 grams/tonne gold, and 77 metres from 471 metres @ 0.55% copper and 0.75 grams/tonne gold.
The newly discovered tourmaline breccias are regarded as part of a major copper-gold mineralized system with significant exploration potential. The total extent of tourmaline breccia may be related to a large geophysical anomaly extending up to 3.5km to the east. Exploration drilling will continue to target the mineralization both along strike to the east and west as well as at depth beneath the current intersections.
Xanadu’s managing director George Lloyd says, “This is the first time was have encountered copper grades greater than 1% over significant intervals at Kharmagtai. The corresponding gold sends the copper equivalent grades over 2%.”
