Project Background

Gold bearing veins first discovered and claimed by Kennecott in 1997

Ben Porterfield, a Kennecott geologist retain claims and artisanal mines vein

from 2000-2010

Porterfield leases property to Anglo Gold Ashanti Exploration USA in 2005

for the first year drill program

International Tower Hill Mines LTD (spin out from Anglo Gold) advances

project 2006 and 2007 with drilling

Terra Mining acquires project through LOI in 2/2010 and JV Agreement

9/2010

Total investment 2005-2007 was $6 million with 168,000 oz of gold and

310,000 oz of silver resources identified through the three seasons of drilling
