Slide 4: South American Minerals Explorer
South American Minerals Explorer • Three quality projects: • Flagship Anzá gold project in Colombia • Early stage El Pantano gold exploration project in Argentina • Ariquemes tin project in Brazil. • Strong balance sheet • Advanced gold project under JV to two of the worlds largest gold miners. Four

Brazil - Ariquemes 5
Slide 6: 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 under explored. • Other metals not explo
Slide 7: Argentina — El Pantano
Argentina — El Pantano / ARGENTINAS EL PANTANO PROJECT
Slide 8: Argentina – El Pantano
Argentina – El Pantano • Large land holding (600km2) in key endowed district. • Mining friendly • Near to major producing mine (Cerro Vanguardia – Anglo). • National scale power lines 40km away • Essentially unexplored, but key geological indicators. • Zero entry cost and low-cost early stages • $3m
Slide 9: Anzá Project
Anzá Project 9
Slide 10: Anzá History
Anzá History • Anzá spun out from Continental Gold into Waymar Resources around 2010. • Waymar drilled 18,000m at APTA prospect to 2014. • Waymar and Orosur merge in late 2014. • Orosur drilled at APTA and Charrascala. • JV deal with Newmont in Sept 2018. • Agnico join Sept 2020 to form Minera Monte
Slide 11: Anzá – late Miocene mid-Cauca belt
Anzá – late Miocene mid-Cauca belt • Primary gold belt in Colombia. • Host to multiple giant gold deposits. • Most sit within a narrow N-S structural corridor. • All porphyry-epithermal systems 11
Slide 12: Anzá – leases and applications
Anzá – leases and applications • Large land holding of +200km2, covering 20km strike of main structures. • Two large applications begin conversion within weeks. • Total land holding will reduce slightly as part of conversion process. • Several new applications on southern margin may be added • Prosp

Slide 14: APTA
APTA • The focus of most drilling due to results, access and Covid (almost 39,000m). • Many high quality intersections – eg/ 59.55m @ 9.61g/t Au • Possibly a hybrid VMS, high level epithermal system. • Attractive but later drilling showed it to be complex. • Will return to it, but big companies need
Slide 15: Pepas Drilling
Pepas Drilling • 12km North of APTA • Drilling over wide area to test multiple targets. • Difficult drilling conditions, several holes failed due to broken ground. • First drilling phase designed to define stratigraphy and major structures. Moderate expectations. • But first hole was spectacular!! •
Slide 16: First hole – PEP001
First hole – PEP001 • PEP001 drilled to target downdip projection of surface samples of 8m @ 20.67g/t Au. • Instead the hole entered mineralisation immediately from surface, returning 150m @ 3g/t Au. • Unexpected, but pleasantly so. • With hindsight, drill pad not optimally located to define the bod
Slide 17: Anzá - Other Prospects and Work
Anzá - Other Prospects and Work • Drilling underway at Pupino, but may pause due to logistics. • Detailed mapping, sampling and geophysics near complete at El Cedro and El Roble. • Previous high grade rock chips here +8g/t Au. • Hope to start drilling in the South this year. • Mapping and sampling i
Slide 18: Anzà, JV
Anzà, JV • Phase 1 completes today – JV partners have earned 51%. • JV partners must exercise Phase 2. • $20m over 4 years to earn total of 65%. • Triggers $2m payment to Orosur. • Creation of new JV structure – may take several months but work should continue. • Phase 3 – additional 4 years to prod
Slide 19: Summary
Summary • Pepas results and Phase 2 finally establish Anzà as world class exploration project. • Two of the world’s largest gold miners paying the bills. • Phase 2 is drill, drill, drill. • $2m strengthens balance sheet. • El Pantano and Ariquemes just starting work. • Looking for new projects and d
