Slide 12: Limon – gold-silver epithermal
Limon – gold-silver epithermal • Large search space for epithermal gold-silver- base metal mineralisation • Evidence of epithermal veins to depths exceeding 600m from previous drilling • Evidence of multiple epithermal vein Hills inoccurrences background within 1.7km x 700m Limon alteration zone • C
Slide 13: El Palmar, northern Ecuador
El Palmar, northern Ecuador • Highly prospective belt of rocks related to the Toachi Fault Zone • To date includes the 2.7Bt Alpala copper-gold porphyry deposit at Cascabel, the 0.53Bt Tandayama-America copper- gold porphyry deposit at Cascabel, and the 1Bt Llurimagua copper-moly porphyry deposit •
Slide 14: El Palmar; T1-T2-T3-T5 porphyry cluster
El Palmar; T1-T2-T3-T5 porphyry cluster • Mineralisation from surface at T1, T2, and T5 • 2.3km long cluster of porphyry targets identified to date; T1 to T5 • Targets could all be related and have geometries that relate to their position on or adjacent to the Toachi fault, and subsidiary orthogonal
Slide 15: El Palmar; multiple large targets
El Palmar; multiple large targets • T3 EPDD026 intersection deep but coincident magnetic anomalies extend towards surface • Increasing confidence that magnetic bodies correlate with gold- copper • T1 already an orebody in its own right • HUGE opportunity 15
Slide 16: El Palmar; comparison with SolGold-Cascabel-Alpala
El Palmar; comparison with SolGold-Cascabel-Alpala • Targets ‘on scale’ with 3Bt Alpala deposit at Cascabel (SolGold) 16
Slide 17: El Palmar; cluster of opportunities
El Palmar; cluster of opportunities • Targets could all be related and have geometries that relate to their position on or adjacent to the Toachi fault • Porphyries have very large vertical extent EPDD026 grades suggest the T3 system can deliver very high grades relative to other porphyry deposits V
