Acero – Overview
Southern Peru (2000) • Altered feldspar porphyry • Potassic alteration • Copper oxides and chalcocite • Two target zones:
(200 m by 700 m and 800 by 1,200 m)
• Drilled 16 diamond holes 3,800 metres
Golden Alliance (2009) • Limited Surface Sampling • 1.15% Cu over 30 m • 0.74% Cu over 50 m • 0.56% Cu over 50 m • No additional work Pembrook • Acquired in late 2012 • Community effort in progress

Acero – Porphyry Copper
• Close proximity to several copper mines
• Large porphyry system • High-grade surface Cu assays • Ability for rapid advance to resource • Drill Log description suggests high-
grade potential – Strong Potassic Alteration – Bornite – Chalcopyrite – Molybdenite
