Strategically located, globally relevant.
Lindian’s three bauxite projects in Guinea – Lelouma, Gaoual, and Woula – are located in one of the world’s premier bauxite mining provinces.
These projects host large-scale, high-quality resources with grades suitable for export to global aluminium producers. The deposits feature favourable mineralogy and are within trucking or rail distance of established port infrastructure at Kamsar and Dapilon.
Lindian’s focus is on unlocking value through strategic alignment with international partners, staged development options and downstream offtake discussions.
Gaoual Project
- High-grade DSO potential
- JORC-compliant resource outlined
- Complementary to Lelouma in infrastructure proximity
- Early development or partner-ready asset
Woula Project
- Smaller-scale opportunity with near-surface mineralisation
- Potential for early production or blending
- May serve as a supporting or trial feedstock site
Lelouma Project
- JORC Inferred Resource of 900 Mt @ 45% Al₂O₃
- Low reactive silica, ideal for refining
- Close to existing heavy haul road corridors
- Large-scale export potential
Gaoual Bauxite – Bouba Plateaux
The Gaoual Bauxite Project (Gaoual Project) is in northwestern Guinea within the Boké Bauxite Belt. It is situated south of the
township of Gaoual in the northern portion of the Kogon-Tomine interfluve, about 65 km northeast of Sangaredi. The Company
has agreements in place to acquire up to 75% of the Gaoual Project. The Gaoual Project’s asset contains conglomerate bauxite at
the Bouba plateaux which is the same type of ore that was initially discovered at the Sangaredi bauxite deposit which is owned by
Compagnie des Bauxites de Guinée (“CBG”).
| Resource (Mt) | Cut-Off (AI2O3 %) | Grade (AI2O3 %) | Grade (SiO2 %) | Category | |
|---|---|---|---|---|---|
| High Grade Resources | 83.8 | 45 | 51.2 | 11.0% | Indicated |
| Total Resources | 101.5 | 40 | 49.8 | 11.5% | Indicated |
Lelouma Project
In October 2020, an updated Mineral Resource Estimate for the Lelouma Bauxite Project (Lelouma Project) was prepared and reported by SRK Consulting (UK) Ltd, in compliance with the JORC Code. SRK used Ordinary Kriging in Datamine to interpolate major oxide sample grades into a 3D block model (utilising percentage-space conversions to honour grade profiles during estimation) and assessed the estimation quality and fully validated the model. The validation process confirmed the robustness of the parameters used and the resultant model.
The inclusion of new drilling data into the existing database enabled the reporting of a resource of 900 Mt at 45.0% Al2O3 and 2.1% SiO2. This additional exploration work has also enabled the definition of 155 Mt at 47.9% Al2O3 and 1.8% SiO2 within the Measured Mineral Resource category confirming the Project’s potential to produce high-grade ore, delivering some of the highest quality ore into Atlantic and Pacific refinery markets.

Woula Bauxite Project
The Mineral Resource Estimate for the Woula Project was prepared and reported by SRK Consulting (UK) Ltd (“SRK”) by constraining the in-situ model using cut-off grades >34% Al2O3 and <10% SiO2, a maximum stripping ratio of 1:1 (thickness overburden / thickness bauxite) and a minimum bauxite thickness of one metre, all to satisfy the criteria of reasonable prospects for eventual economic extraction1. No pit optimisation was used to constrain the Mineral Resource due to the very shallow and low stripping nature of the deposit. All tonnages and grades are reported on a dry basis. These parameters are guided by and have been validated using SRK’s experience of other Guinea bauxite operations.
| Cut-Off Criteria | Mineral Resource Category | Tonnes (Mt) | AI2O3 (%) | SiO2 (%) |
|---|---|---|---|---|
| >34% Al2O3 10% SiO2 / >1m Thick / <1 Strip Ratio (waste:ore thickness) | Inferred | 64 | 38.7 | 3.1 |
