7. Project Background
7
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

Terra’s pre-money valuation of approximately $16 million is conservative using levels far
below current gold spot price of $1,500 per ounce. Management has significantly
discounted the expected gold resources of 1,000,000 ounces.

Operation Plans call for a conservative annual production of 30,000 ounce per year of gold in an
underground mining operation at Terra when fully deployed, which equates to $30M per year in
profits at full operation.
The Company’s assumptions conform to the International Tower Hills (ITH) resource report dated
2/1/08.
