New resource estimate should be better...The reason I beleive resource will grow quite a bit
• Billiton resource estimate was predicated on an open pit mining method, with no inclusion of oxide mineralization and deep drilling.
• Billiton resource estimate was based upon 80 drill holes (15,903m); Blind Creek’s new NI 43-101 resource estimate, currently in progress, will include 52 subsequently drilled infill, extensional and deeper holes (9,290m).
• Blind Creek resource modeling has defined continuous, higher-grade and discrete Zn+Pb domains which is expected to provide for a higher resource grade, amenable for a potential combined open pit / underground mining operation.
• Significant potential to enhance mining and processing economics (and mineral resource size and tenor) through incorporation of recent metallurgical advances made in oxide material processing and recoveries.
• Estimate potential resource grade, tonnage increase up to 50% with inclusion of oxide mineralization.
• Recent discovery of new mineralization 3km to east (Far East Zone) in 2004.
• Base metal grades increase with depth, with notable copper and silver grade increase at depth in the West Zone.
• The Blende Deposit trend has been defined over an 8 kilometre strike length and 700 metre vertical range, with mineralized zones remaining open along strike and at depth.
