    Aldridge in and around the Yenipazar

    deposit.

    Open pit target: up to 70 m thick, sheet-like deposit, contained in depths between 35-190 m below surface.

  • New 43-101-compliant resource estimate completed by P & E Mining Consultants Inc. (“P&E”), stating a total of 28 Mt within an optimized open pit shell, in two resource categories:

43-101-compliant, independent Yenipazar resource increase, October 2008

This resource is based on more than 46,000 drill-meters in 321 reverse circulation (RC) and 11 diamond holes. Another 872 m was drilled in 8 RC-holes, after the database was passed to P&E. The detailed P&E-report will be available at the end of October 2008.
 
  • Northern part of Yenipazar drill plan for 321 RC-holes in total drilled by Aldridge, plus the two Aldridge diamond holes (YPD1 and 2). The ES-diamond holes were drilled by Anatolia Minerals.

    Aldridge diamond holes (YPD1

    and 2). The ES-diamond holes

    were drilled by Anatolia Minerals.

     Environmental advantage: Yenipazar ore has only trace amounts of arsenic (0.0025 %) and cadmium (0.005 %), in contrast to other VMS-deposits.
 
  • After the last P & E resource estimate, another 206 RC-holes and 2 diamond holes were drilled by Aldridge, showing that the Yenipazar deposit has more than three times the strike length than indicated in the P & E study. Along the entire strike, as drilled so far, the deposit has similar thickness (up to 70 m), width (up to 200 m), and grades. There is good potential to multiply the resource and to upgrade the category for significant portions of the deposit (see maps of drill holes on the right-hand side).
 
  • The total drilled by Aldridge to early June 2008 is 43,850 m RC in 321 holes and 277 m diamond (core) in 2 holes.
 
  • 400 km2 tenement with good potential for further mineralization (see map with central part of the license area on the top right-hand side).
 
  • Excellent infrastructure in level and low-relief terrain.

    Drill-Hole-Plan

    Since November 2006, Aldridge applies an XRF-field device that gives the rough grades of base metal mineralization. The relatively high detection limits of this technology inhibit reading ore-grade precious metals, and even the readings on base metals have often large errors (+/-50 % range, and sometimes more). However, Aldridge-testing demonstrated that the method reliably allows to distinguish barren from mineralized RC-samples. This is used to avoid sending barren samples to the laboratory, and to re-direct drilling towards mineralized zones, avoiding to drill barren holes. In only one year, this saved about CAN$ 120,000 of analytical cost for drilled samples. In reality, the saved cost is much higher for the saved drilling & analytical cost on barren holes that would have been drilled without the immediate XRF-direction. In the Excel table with drill results below, many drill-intervals do not have laboratory results, because they were identified as barren in the field.

 

 

  • Long section, N-S through the Yenipazar deposit to show deposit depth and moderately folded mineralization. On some E-W-drill lines (40-m-spaced holes), only 1 hole was executed, probably hitting the deposit in a marginal position. To show that mineralization is continuous, also these weakly mineralized holes are included in the long section. Richer results are expected on these E-W lines on follow-up drilling during the coming months.

    The Yenipazar property is subject to a farm-in agreement with Anatolia Minerals Development Ltd. (TSE: ANO). According to the agreement from Dec 1, 2004 and the amendment from July 21, 2006, Aldridge has the option to acquire 100 % of the license rights for a total exploration expenditure of US$ 6M over six years, plus a staged payment of total US$ 1 M to Anatolia during the six years. Anatolia has a net proceeds interests (NPI, in simple terms: revenues minus operational cost) of 6 % until revenues totalling US$ 165 million are yielded, and 10 % NPI thereafter. To October 2007, Aldridge spent approximately US$ 3.5 M on the Yenipazar project.
