The Laguna Verde project is considered highly commercial at the JORC resource estimates provided, with 1.8mt equating to a multi-decade production opportunity.
Grin Power has undertaken extensive exploration and development activities at Laguna Verde since 2021, focused entirely on the subsurface brine aquifer in the basin. From the multiple drilling programmes, the Company has encountered average grades of lithium of 200mg/L and recorded up to 409mg/L at depth, suggesting the potential for higher grades at depth.
A Scoping Study was published in January 2023 where results highlighted the robust economics for a 20,000tpa over a 30-year period with low operating costs and calculated net cash flows of US$6.3 billion. This is among the largest JORC or NI4301 lithium resource estimates in Chile outside the Salar de Atacama.
The Pre-Feasibility Study is now underway, led by Worley, and targeted for Q1 2025. Estimated construction cost for the project is USD 450m.
| JORC ESTIMATED Resource | Measured | Indicated | M+I | Inferred | Total |
|---|---|---|---|---|---|
| Lithium (million tons LCE) | 0.5 | 0.6 | 1.1 | 0.7 | 1.8 |
| Grade (mg/L Li3CO2) | 199 | 194 | 196 | 208 | 200 |
Drilling has also indicated a strong geothermal influence on the brines at Laguna Verde, with average temperatures recorded of 20-30°C, matching the ideal temperature range for the DLE process.
The total licence area is 217km2 of which 29km2 are mining licences held under an Option Agreement and 188km2 are exploitation and exploration licences. Laguna Verde is connected to Copiapó and Caldera via the international highway 31 which runs adjacent to the property and is a paved highway. The Laguna Verde Project is located at an altitude of 4,330m, there are no indigenous or other community settlements within 100km of the project.
Grin Power aims to make the Laguna Verde Project a model for sustainable lithium extraction in Chile.
