El Palmar Copper-Gold Porphyry Project – Northern Ecuador (Sunstone 70% – acquiring up to 100%) Sunstone has made a significant discovery at the highly prospective El Palmar gold-copper porphyry project, located in northern Ecuador, 60km north-west of Ecuador’s capital Quito. Travel time to site from Quito is approximately 3 hours. The property sits on the regionally significant Toachi Fault Zone, the same regional structural belt that hosts the 2.66Bt Alpala copper-gold porphyry deposit grading 0.25g/t gold and 0.37% copper, and the 0.53Bt Tandayama-America deposit grading 0.19g/t gold and 0.24% copper within the Cascabel project (see www.solgold. com.au for details), and in the vicinity of the 1Bt Llurimagua copper-molybdenum porphyry deposit grading 0.89% copper and 0.04% molybdenum (Figure 4).
