Slide 4: Current status
Current status • Uruguay closure near completion. • Anzá now being operated by Newmont/Agnico. • +15,000m drilled since restart in late 2020, +38,000m in total • Drilling at APTA completed for the moment – rigs moved north, two at Pepas, one at Pupino. First results imminent. • El Pantano positive r

Slide 6: Anzá Status
Anzá Status • Over 15,000m drilled since late 2020, over 38,000m in total. • Numerous mineralized zones identified at APTA – high grade but complex. Decision taken not to drill to resource. • Project operations handed over to JV partner. • Focus finally shifted to northern prospects after 10 years.
Slide 7: Regional Potential
Regional Potential • Almost all drilling since 2012 at APTA. Not because it was best, but because it was easiest to access and was safest during Covid. • Drilling is expensive – we need targets first. • Large sampling, mapping and geophysics programs through 2021. Followed by development of access.
Slide 8: Porphyry-Epithermal. A question of depth
Porphyry-Epithermal. A question of depth • Wide variety of ore body types derive from the Porphyry-epithermal model • Require source, fluid pathway and trap site. • Key is the interaction of upwelling fluids with surrounding rocks and waters • Buritica is lower in the system than APTA – Carbonate Ba

Slide 11: Anzà, what next?
Anzà, what next? • Results at Pepas soon. • Four rigs in the north, regular newsflow. • Second rig to start at Pupino soon. • Geo teams moved to south of project. More difficult access. • Progress on application conversion. • Exercise option to move to Phase 2 by Sept 6th 2022. • Form formal JV, $2m
Slide 12: Brazil - Ariquemes
Brazil - Ariquemes • Large land holding (3,000km2) • Mining friendly region. • $3m over 4 years to earn 75%. • Key but unloved energy metal • High metal price, supply is fragile and very little ESG compliant production • Major province but under exploited and explored. • Other metals not exploited.
Slide 13: Ariquemes – Granites and Greisens
Ariquemes – Granites and Greisens • Three target styles – granite hosted, higher level veins, alluvial 13

Ariquemes – Granites and Greisens • Three target styles –higher level veins (BF), granite hosted, alluvial Bom Futuro 14
Slide 15: Ariquemes – work commencing
Ariquemes – work commencing • Engaged local consultants • Data compilation commenced • Established commercial structures (low cost and no long-term liabilities) • Stream sediment sampling July • Ongoing mapping, trenching, target generation. • Price coming off reduces hype – opens up opportunities f
Slide 16: Argentina – El Pantano
Argentina – El Pantano • Large land holding (600km2) in key endowed district. • Mining friendly • Few environmental issues • Near to major producing mine (Cerro Vanguardia – Anglo). • National scale power lines 40km away • Early stage but key geological indicators. • Zero entry cost and low-cost ear
Slide 17: El Pantano – basic exploration
El Pantano – basic exploration • No drilling ever undertaken. • Jurassic volcanics and major NW structural corridor. • Lithology and alteration suggestive of major low- sulphidation epithermal system • Anomalous high-grade sampling in and around the project • Two phases of Geochem undertaken. 17
Slide 18: El Pantano – positive first signs
El Pantano – positive first signs • Preliminary soils positive and indicative of epithermal system. • Return after winter for more targeting. View to drill in medium term? • Key is to add maximum value at minimum cost. 18
Slide 19: Summary – the new Orosur
Summary – the new Orosur • Anzà progressing as a major project off balance sheet. • Results from northern drilling imminent. • Nearing decision point to move to Phase 2 • Uruguay wound up. • Several other projects operating in parallel. • Balance sheet remains strong. 19
