Drilling at Bilbao

Xtierra will commence a new 2,500 metre drill program in early March 2011 to follow-up on a high grade silver zone previously encountered along the western margin of the Bilbao deposit which is believed to be structurally controlled. Previously reported (24 Sep. 2010) intersections of interest included a 20.00 m wide zone averaging 90g/t Ag intersected in drill hole X85; a 1.0 m interval averaging 860 g/t Ag in hole X84B; a 1.0 m interval averaging 528 g/t Ag and a 6.0 m interval averaging 847.5 g/t Ag (including 2.0 m at 2,400 g/t Ag) in hole X26.

A preliminary evaluation of the drill data suggests the presence of two parallel zones with elevated silver (plus some gold) values. The silver-enriched zone extends over a strike length of at least 300 metres.
