Tocantinzinho Deposit




Granite-hosted, intrusion-related, disseminated, low grade/bulk tonnage gold deposit
M&I resource of 2.4 million ounces @ 1.06 g/t gold
Regionally, mineralization associated with NW-trending Tocantinzinho Trend
On a district scale, mineralization occurs in a structurally favorable site in the periphery of
the nearby Maloquinha intrusion
2011-2012 Program


Exploration efforts focused on targets peripheral to deposit, within ~5km radius
Focused on Tocantinzinho Trend and geophysical/geochemical targets
2011 Work Completed

17,270 metres of diamond drilling in 56 holes
2,800 metres of auger drilling in 146 holes
3,000 soil samples covering 47 km2
800 metres of tailings delineation drilling in 57 holes
Total Expenditure of $11.4M for 2011

 Mid 80’s to mid 90’s: Intense garimpo activity.
1997-1998: ALTORO’s soil, auger and channel sampling:
- NW trending >200 ppb Au soil anomaly with 1,000 x 500 meters;
- Channels intercepts 38 m @ 2.68g/t Au
2004: Jaguar Resources started a drilling program:
- DDHoles 01 and 04 discovered the Tocantinzinho
- Intercepts 91.90m @ 1.01g/t and 170.20m @ 1.84g/t Au
2008: Eldorado Gold starts acquisition of Brazauro and become a partner in
Tocantinzinho Project (Resources around 1 Moz)
2010: Eldorado completes acquisition of Brazauro
2008 to 2011: Exploration increased Resources from 1 Moz to 2.4 Moz
 2015 Production
