Golders consultants report conceptual modeling of heap-leach treatment facility which suggests low capital and processing costs
TORONTO, Canada, March 31, 2009 – Lydian International Ltd. (TSX:LYD), a diversified U.K. mineral exploration and development company, today announced results of a preliminary scoping level design study of a heap leach facility for its Amulsar gold discovery in Armenia. The study was conducted by Golder Associates UK Limited in conjunction with KD Engineering of Tucson, Arizona.
The study assumed a 1Moz resource and an ore grade of 1g/t with recoveries of 94% (in keeping with recent NI-43101 compliant resource estimate published 18/03/08 and results of metallurgical testing by SGS Lakefield published 13/08/08). An estimated stripping ratio of 0.64 was used for this exercise and two resource scenarios assuming i) “run-ofmine” (no crushing or screening required) and ii) required crushing and screening. Modeled Production (Table 1) and costs (Table 2 - at 2008 rates) are presented for a 1Moz resource. Capital costs reported in the study assumed a plus or minus 40% contingency. All costs are in US-Dollars and exclude mining costs, mine hauling roads, escalation and mine and contractor camps, and were developed based on US project experience.
The conceptual design includes features to minimise impacts to the surrounding environment, wildlife, and groundwater. These design components include surface water diversion systems, groundwater monitoring wells, fencing, and leak-collection and recovery systems associated with a composite liner within the entire heap leach pad facility footprint, plus an additional double composite liner system for the process ponds.
Tim Coughlin, Lydian’s President and CEO commented: “We are pleased with the results of this preliminary analysis which suggest low capital and treatment costs at Amulsar. This is due primarily to ease of access and excellent infrastructure. The project is located adjacent to the main highway some 240km south of Armenia’s capital Yerevan. This main artery provides ready access to high-tension power lines, natural gas and water. Further metallurgical testing will be conducted this year to better ascertain recoveries and to test potential for run of mine treatment”
Amulsar is a high-sulphidation type epithermal gold project located in central Armenia. Lydian identified the gold bearing potential of the project in mid-2006, started initial drilling in 2007, and in 2008 completed a 13,000m drill program to test the bulk tonnage potential and estimate a gold resource. The resource is NI-43101 compliant and estimated to an inferred category of one million ounces gold. The Amulsar license is 95% owned by Lydian’s wholly owned Armenian subsidiary (Geoteam CJSC). The project is currently being explored as part of a 50/50 joint venture with Newmont Overseas Exploration Limited, a wholly owned subsidiary of Newmont Mining Corporation (NYSE:NEM).
