Interesting acqusition given Cerro Morro contains only about 2.3 million ozs and is in Argentina.
If Yamana really wants to go elephant hunting know doubt they're eyeing new discoveries and deposits in Colombia - a much safer jurisdiction.
La Colosa in Colombia is the largest discovery made in Latin America in the last few yeras. It has currrent resources of about 25 million ozs http://www.auroresources.com/s/Lacolosa.asp.
Hopefully Yamana's acqusition kickstarts the junor resource markets.
