Overview
Exploration is the lifeblood of the mining
industry with all mining companies increasingly
hungry for quality projects.

• Focused on the discovery and development of
  quality precious and base metal projects in
  Brazil and Peru
• Concentrated on low-cost / high-reward phased
  exploration for maximum shareholder value
• Three advanced projects in established mining
  districts (100 owned) - El Aguila, Tangara and
  Falcao demonstrate potential to host major gold
  and silver-zinc systems
• First Phase drill programmes completed at Tangara
  and El Aguila early results indicate potential
  for large mineral systems

4
Key Strengths

• Established, experienced economic geological
  management team
• Ability to risk manage low cost high reward phase
  of ED
• Control of district/large-scale targets located
  in prospective mineral terrains with existing ore
  deposits hence increases probability of success
• Project and target selection criteria designed to
  identify potential to host major US1 billion
  in-situ value
• Generative programme to increase asset base and
  provide pipeline of quality exploration projects
• Close contacts with mining companies in Brazil
  Peru - aim to be a preferred local exploration
  partner Troy Resources JV confirms business
  model
• Lack of exploration funding has created an
  imbalance in supply and demand of mineral
  projects Horizonte well positioned to exploit
  this opportunity

El Aguila - Results
Results of June 2006 surface and underground work
programme at Pacos Hill

• Veta Sur returned 6 metres grading 10.7 oz/t
  Ag, 7.8 Pb and 5.9 Zn. (R-6502 R-6503)
• Trench sampling returned 16 metres grading 4.6
  oz/t Ag, 2.8 Pb and 0.7 Zn, including 2 metres
  at 9.1 oz/t Ag, 6.8 Pb and 1.1 Zn
• Underground sample returned 1.2 metres grading
  13.9 oz/t Ag, 8.8 Pb, 2.2 Zn and 0.46 g/t Au

Work defined new geological model, metal grades
not only linked to veins but occur as replacement
structures giving significant tonnage potential
