Slide 3: GMN Major Projects in Eastern Brazil
GMN MAJOR PROJECTS IN EASTERN BRAZIL Ararenda – Major Copper-Gold multi element anomalies. Next steps IP and soil sampling followed by drilling. Araxá – Niobium-REE targets at early stages, with combined radiometric, magnetic and structural targets identified. Next steps For personal use only comple
Slide 4: Project - Jequié REE Province
DOWN UNDER PROJECT - JEQUIÉ REE PROVINCE Tenements selected to cover • Good REE source geology regionally For personal use only • Tenements cover high thorium anomalies • Presence of fully to partly preserved lateritic profiles • Major shear zones within main Jequié tenement block • Adjacent to know
Slide 5: Thorium Radiometrics
THORIUM RADIOMETRICS • Yellow stars show diamond drill targets, one currently being For personal use only drilled for resources • GMN tenements lie within the 20-40 km wide radiometric thorium-uranium anomaly which defines a REE productive zone (light green on the Map). • GMN tenements cover favoura
Slide 6: Project in the Jequié REE Province Summary
DOWN UNDER PROJECT IN THE JEQUIÉ REE PROVINCE SUMMARY • Ongoing Diamond Drilling at the high-priority Irajuba prospect For personal use only • Pipeline of major stream sediment geochemical anomalies and reconnaissance drill targets identified • Drill permitting ongoing for anomalous areas • Regional
Slide 7: Project in the Jequié REE Province
DOWN UNDER PROJECT IN THE JEQUIÉ REE PROVINCE • An orientation stream sediment sampling program conducted in 2024 on known mineralised deposits of competitor areas returning peak values of 282 ppm TREO. For personal use only • GMN then commenced an extensive stream sediment sampling program on GMN t
Slide 8: Diamond Drill Targets
DOWN UNDER | DIAMOND DRILL TARGETS Diamond Drill targets defined by reconnaissance auger drilling on high order stream sediment anomalies in high thorium anomalies. All GMN’s stream sediment samples have greater values or For personal use only similar values to orientation samples on competitor’s de
Slide 9: Jequié Region | Extensive Metallurgy
JEQUIÉ REGION | EXTENSIVE METALLURGY • Extensive metallurgy conducted on deposits in CIA % For personal use only the region 100 • Extracted with ammonium sulphate solution with adjustment to pH 4. Economic level recoveries recorded in test work. 95 • Deleterious U and Th not extracted from the REE R
Slide 10: Drill Target IR
DOWN UNDER | DRILL TARGET IR - 1 For personal use only Mineralisation open to depth and all directions TREO Mineralisation greater than the cut off grade of 400 ppm TREO and greater than 200 ppm TREO-CeO2 in red Chemical Index of Alteration (CIA) shown in green; CIA generally reduces systematically
Slide 11: Exploration Targets IR
DOWN UNDER | EXPLORATION TARGETS IR - 1 Exploration Targets are pre resource estimates of what may be present based on knowledge at the time. For personal use only IR – 1 Exploration target based on reconnaissance drilling carried out using machine powered shell augers, stream sediment sampling anom
Slide 12: Drill Target IR
DOWN UNDER | DRILL TARGET IR - 1 Reconnaissance drilling can find mineralised profiles within the For personal use only anomalous catchments. Diamond drilling can penetrate the entire weathering profile and demonstrate potential resources. Hard rock targets are very likely to be surrounded by larger
Slide 13: Drill Target IR
DOWN UNDER | DRILL TARGET IR - 1 Landowner map showing ongoing negotiations for access and drilling on areas outside the Initial For personal use only Exploration Target, on GMN tenements. One landowner on the point of signing, another still negotiating. Landowner relations are critical and take tim

Slide 15: Laterite IAC v Hard Rock Mine Costs
LATERITE IAC V HARD ROCK MINE COSTS IAC deposits are low capex compared to most hard rock deposits, low environmental impact and simple metallurgy compared to hard rock deposits. CAPEX and OPEX For personal use only The Araxá project in Brazil has a LoM (life of mine) of 40 years and overall total i
Slide 16: Target Types and Scales
TARGET TYPES AND SCALES Three target types are present in the Jequie REE Province IAC Target – very large, simple to find with stream sediment sampling , then reconnaissance auger For personal use only drilling anomalies, then diamond drilling to determine resources. This target is amenable to low O
Slide 17: Explanatory Notes: Drilling Areas and Exploration Understanding on GMN Ground
EXPLANATORY NOTES: DRILLING AREAS AND EXPLORATION UNDERSTANDING ON GMN GROUND GMN initial drilling target is one of the best stream sediment anomaly areas sampled so far. Not all tenements have been sampled yet. GMN uses multi-element assays to find the best TREO geochemical anomalies and additional
Slide 18: Explanatory Notes: Drilling Areas and Exploration Understanding on GMN Ground
EXPLANATORY NOTES: DRILLING AREAS AND EXPLORATION UNDERSTANDING ON GMN GROUND Principal characteristics useful for deposit search are: Presence of the right metamorphic suites e.g. charnockitic gneisses, leucogranites which GMN has seen in the field, on several sites, including adjacent to some of t
Slide 19: Explanatory Notes: Drilling Areas and Exploration Understanding on GMN Ground
EXPLANATORY NOTES: DRILLING AREAS AND EXPLORATION UNDERSTANDING ON GMN GROUND The exploration targets GMN has are capable of producing economic scale and high grade REE deposits, particularly when you look at the very high MREO percentages in our results. The various additional targets we have ident
