Slide 4: Investment Opportunity
Investment Opportunity • Key messages • Exposure to 2 giant gold-copper-silver assets • In southern Ecuador, the Limon gold-silver discovery is a breakthrough opportunity supporting a high- grade front end to a targeted 10Mozs gold equivalent camp at the Bramaderos project • In northern Ecuador, the
Slide 5: Bramaderos, Southern Ecuador
Bramaderos, Southern Ecuador Drill core processing facility Limon Brama-Alba • 4,984ha concession • Adjacent to the Pan American Highway • At ~900m asl • The project is supported by good infrastructure (hydroelectric power, regional airport nearby) • 93% of Ecuador’s power is generated from renewabl

Slide 10: Limon – the game changer – recent drill results
Limon – the game changer – recent drill results Significant high-grade intersections in LMDD017 and LMDD026, include; ▪ 176.7m at 1.1g/t AuEq* (0.97g/t gold and 10.1g/t silver), from 6.8m in LMDD017, including ▪ 15.0m at 4.0g/t AuEq* (3.9g/t gold, 7.7g/t silver), from 81.2m, and ▪ 26.0m at 2.3g/t Au
Slide 11: Limon – gold-silver epithermal
Limon – gold-silver epithermal Hills in background 11
Slide 12: Limon – gold-silver epithermal
Limon – gold-silver epithermal • Very significant discovery; delivers the higher-grade front end for a larger development • Large search space for epithermal gold- silver-base metal mineralisation Hills in background • Evidence of epithermal veins to depths exceeding 600m from previous drilling • Ev
Slide 13: Limon – gold-copper-silver porphyry
Limon – gold-copper-silver porphyry • 97.6m at 0.71g/t gold and 0.23% copper in trench • 79m at 0.52g/t gold, 0.19% copper, 9.4g/t silver from 90m in LMDD010 Large porphyry target sitting below the high grade epithermal Several independent datasets make this a robust target Hills in background 13
Slide 14: 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 (0.53% CuEq) at Cascabel, the 0.53Bt Tandayama- America copper-gold porphyry deposit (0.36% CuEq) at Cascabel, and the 1Bt Llurimagua coppe
Slide 15: 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 16: El Palmar; multiple large targets
El Palmar; multiple large targets • T1; 800m long (in NW-SE orientation) already an orebody in its own right • T1; 21 drill holes completed, gold-copper from surface to 500m below surface, intersections include 160m at 0.7g/t gold and 0.2% copper from 52m (LMDD001) • T3; EPDD026 and 028 intersection
Slide 17: El Palmar; multiple large targets
El Palmar; multiple large targets • Cross section, same scale comparison with the 3Bt Alpala deposit at Cascabel (SolGold) • Depth to top of the main Alpala orebody is ~700m • Comparable scale to the evolving El Palmar exploration 17
Slide 18: El Palmar; comparison with SolGold-Cascabel-Alpala
El Palmar; comparison with SolGold-Cascabel-Alpala • Plan view, same scale comparison with the 3Bt Alpala deposit at Cascabel (SolGold) • At >0.3% CuEq Alpala orebody measures 500m x 900m • Depth to top of the main Alpala At ~1,000m below surface orebody is ~700m • Comparable scale to the evolving E
Slide 19: El Palmar; cluster of opportunities
El Palmar; cluster of opportunities Targets T1 to T5 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 – can be > 1,000m EPDD026 and 028 grades suggest the T3 system can deliver EPDD026 very high grade
Slide 20: What’s ahead
What’s ahead ✓ Bramaderos • Limon gold-silver epithermal discovery will fundamentally change Bramaderos • Limon gold-silver epithermal discovery will deliver the near surface higher-grade front end needed for a larger development • Deliver additional discoveries at Melonal, Limon porphyry, Porotillo
