YENIPAZAR GOLD-SILVER-COPPER-ZINC-LEAD PROPERTY
Property Overview
The Yenipazar gold-silver-copper-zinc-lead property (the “Yenipazar Property”) is the Company’s most advanced property and is located at the geographic center of Turkey, approximately 220 kilometres east-southeast of Ankara, the capital city. The Yenipazar Property is easily accessible via public roads and has good access to rail transportation and electrical power supply.
Aldridge has identified a mineral deposit on the Yenipazar Property which falls into the broad category of a metamorphosed volcanogenic massive sulphide (“VMS”) deposit (the “Yenipazar Deposit”). The Yenipazar Deposit has a currently determined strike length of 1700 metres (open in one direction) averaging 150 metres in width and approximately 25 metres in thickness at depths between 30 and 190 metres. Much of the orebody is sitting at a depth of approximately 80 metres.
From 2005 to 2010, the Company drilled 369 resource definition holes, including 363 reverse circulation (“RC”) holes for 49,085 metres at the Yenipazar Deposit. A further 918 metres was completed in 6 diamond drill holes, and 9 holes were cored by Anatolia Minerals, now Alacer Gold, for total of 2,016 metres in the late 1990’s. The Aldridge diamond drill holes were collared approximately five metres from the corresponding RC hole for duplication and metallurgical purposes. Overall, the metal grades improve with diamond drilling and the results confirm very good lateral continuity of the resource at the five metre-scale. Mineralized horizons appear to vary only slightly in thickness and elevation, which is an important aspect for open pit mining. As of May 2011, Aldridge is drilling approximately 30 diamond holes of large diameter throughout the deposit to determine variability parameters for the ore. The drilling of these holes will provide data to be used in the Company’s forthcoming feasibility study, approximately 8-9 tonnes of material for metallurgical testwork, and the potential to upgrade the resource.
In December 2010, the Company announced positive results from an independent, National Instrument 43-101 compliant, Technical Report and Preliminary Economic Assessment on the Yenipazar Property prepared by P&E Mining Consultants Inc. (“P&E”), EHA Engineering Ltd. and BC Mining Research Ltd. (the “PEA”).
The PEA states that the Yenipazar Deposit has favourable economic potential as an open pit mine producing copper, zinc and lead concentrates containing quantities of gold and silver. The base case economic analysis contemplates an average life-of-mine strip ratio of 4.5:1 (including the pre-stripping), a 5,700 tonnes per day mill feed rate and a 12 year mine life. The following tables provide itemized summaries for the metal prices used in preparing the PEA and economic highlights of the PEA:
