XTIERRA WILL START NEW DRILL PROGRAM AT BILBAO HIGH GRADE SILVER TARGET

Dublin, 3 March, 2011 - Minco Plc (London AIM | MIO), reports that Xtierra Inc. yesterday announced that all outstanding warrants with an expiry date of March 1, 2011 had been exercised to raise proceeds of $3,108,000 (Canadian).

With the exercise of the 10,360,235 warrants, the issued and outstanding share capital of Xtierra is now 100,619,448 shares. There are 16,980,475 warrants and 4,830,000 options outstanding and "in the money." The proceeds of the warrant conversion brings Xtierra's current working capital to approximately $8.8 Million (Canadian).

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.
