Resende Critical Metals Project
Tin, Tantalum, Lithium and Rare Earth Elements. Minas Gerais, Brazil.
The Resende Project is an exploration project in Minas Gerais State, Brazil, covering eight mineral right claims totalling approximately 133 square kilometres. The project sits 17 kilometres east of AMG Lithium's Mibra spodumene mine, within the Sao Joao del Rey pegmatite province.
Exploration has defined two distinct target types. In the eastern tenements, soil sampling has identified three drill-ready target zones prospective for tin, tantalum, and lithium. The highest-priority target (Zone A) is interpreted to sit along strike from the same greisen unit that hosts AMG's Mibra Mine, which produces tin, tantalum, lithium, and feldspar concentrates. In the western tenements, soil grid sampling over seven drainage basins has identified two follow-up areas prospective for rare earth elements, with TREO values exceeding 1,000 ppm.
Diamond drilling at Target Zone A and auger drilling over the REE areas were planned for February/March 2026.

Project Advantage
| Category | Detail | Description |
|---|---|---|
| Location | Geological setting | São João del Rey pegmatite province, 17 km east of AMG Lithium’s producing Mibra Mine in Minas Gerais, Brazil. |
| Scale | Permit area | Eight mineral right claims covering approximately 133 sq km. |
| Sn/Ta/Li Targets | Drill-ready zones | Three target zones. Zone A sits along strike from the Mibra Mine greisen unit, covering 1,600 m strike × 300 m width. |
| REE Targets | Follow-up areas | Two areas with TREO exceeding 1,000 ppm, both open to the northwest. Auger drilling planned. |
| Geochemistry | Soil sampling | Peak values reaching 60× (tin), 70× (indium), and 30× (bismuth) above average upper continental crust values. |
| Multi-commodity | Mineral diversity | Tin, tantalum, lithium, and rare earth elements across a single project area in an established Brazilian mining province. |
Potential Value Catalysts
- Diamond drilling results from Target Zone A
- Auger drilling results from REE Areas 1 and 2
- Resource definition across the tin, tantalum, and lithium target zones
- Further exploration of Target Zone B and Target Zone C
- Advancement toward a maiden resource estimate
Tin, Tantalum and Lithium — Eastern Tenements
Systematic soil sampling has defined three anomalous target zones in the eastern tenements, all prospective for tin, tantalum, and lithium.
Target Zone A (highest priority): Interpreted to intersect near-surface fresh greisen — the alkali granitic unit responsible for mineralisation at AMG’s Mibra Mine to the southwest and for historical alluvial tin production at Paiol to the south. Zone A covers a strike length of 1,600 metres and width of 300 metres. Peak soil sampling values reached approximately 60 times (tin), 70 times (indium), and 30 times (bismuth) above average upper continental crust values.
Target Zone B and Target Zone C: Additional anomalous areas defined by soil sampling. Further work will follow based on Zone A results.
Rare Earth Elements — Western Tenements
Soil grid sampling over seven drainage basins in the western tenements identified two priority follow-up areas with anomalous TREO values exceeding 1,000 ppm. Auger drilling was planned for February/March 2026 to further define these targets.
-
Area 1: 2 km × 1 km, open to the northwest
-
Area 2: 3 km × 1 km, open to the northwest
