Uzunbulak Cu Au Porphyry - Summary
• Cu Au system developed over 5km long strike length
• 3 zones in southern 2km of system with interesting Cu Au & classic porphyry style veining (5 to 50% range)
• Indications of higher grade Au to 2.3 ppm (Au enriched)
• Cu to 2.6 % (supergene?)
• Modest surface dimensions - may represent the upper portions of more extensive system at depth
• Good access and relatively low altitude (>2000m)
• Minimal work to make drill ready

Karabalta Summary
• Raw reconnaissance property
• Two areas of strongly anomalous Au-Cu-Ag on edge of ring fracture
• Northern Zone - rock sampling Av. 1.7 ppm (peak 42 ppm)
• Southern Zone – contiguous Au in drainages and rock float with 4.3 ppm Au

Ak Bel - Summary
• Structure – crustal suture / orogen oblique / host structure.
• Buried intrusive - heat engine / metal source?
• Carbonaceous / pyritic host rocks.
• Alteration sericite – albite – Kspar – carbonate.
• Mineralization Au-pyrite-(basemetal)
• Drilled 2.5 holes of minimum 9 hole program in the Ak Bel• No significant gold in drill holes to date (Results pending in Holes 2 and 3) • Technically higher priority holes are yet to be drilled• Ak Bel is one of a number of Kentor’s prospect areas along strike from the +10 M.Oz Kumtor District

Kentor – 2005 Review• Range of quality 100% owned Au (Cu-Au) projects derived
from systematic targeting
• “Drill ready” Cu Au porphyry – Uzunbulak
• Significant gold in soil & rockchip at new Barkol prospect areas
• Highly anomalous Au (Cu Ag) in rockchip and stream sediment two new zones in Karabalta
• Ak Bel - along strike from the +10m oz Au Kumtor District
• Ak Bel - 2.5 of 9 priority holes drilled with no significant Au (results pending)
• Ak Bel - best targets yet to be drilled
• Ak Bel - one of a number of Kentor’s prospect areas at Ertash
