Maricunga JV, Chile
Location:
Atacama Region, Chile
Ownership:
51% LPI
Status:
PEA 4Q17, Definitive Feasibility Study 1Q19, EIA 1Q20
Resources:
2.07 Mt LCE at 1,167 mg/l & 5.38 Mt KCI at 8,500 mg/l
Highlights
- Located within the “Lithium Triangle” in northern Chile, home to the largest and highest quality lithium brine deposits
- Highest quality pre-production lithium brine project in South America and the second highest-grade lithium brine resource at 1,167 mg/l lithium and 8,500 mg/l potassium
- Most advanced project in Chile outside of the mine expansions by SQM and Albemarle
- Fully funded development-stage project with financial investment decision to commence construction expected in 2020
Overview
The Maricunga project lies adjacent to the Chile-Argentina Highway 31, 170 km northeast of Copiapo and 250 km from the port of Caldera. A 23kV power line crosses the property and is connected to Chile’s 220kV power grid.
Maricunga is a high-quality brine resource with high brine grades, high flow rate characteristics and high drainable porosity and permeability. The 2019 JORC and NI 43-101 compliant resource estimate for the deposit totals 2.07 Mt LCE & 5.38 Mt KCl from surface to 200m depth. Significant potential for resource expansion lies in an exploration target of 1.0 – 2.5 Mt of LCE and 3.0 – 6.6 Mt of KCl between 200m and 400m depth. The exploration target has been drilled to 360m and remains lithium enriched and open at depth.

Preliminary Economic Assessment – Valuation Update
Current Program
The first lithium carbonate sample has been produced from Salar de Maricunga (Feb 18) at GEA facilities in Germany. The brine was concentrated at the pilot plant solar evaporation ponds at the Maricunga site for almost 12 months, and subsequently treated at the GEA lab in Duisburg, Germany, to purify it and precipitate lithium carbonate suitable for battery grade specification similar to those produced in Chile by Albemarle and SQM. The process route is based on conventional technology and comes with the know-how that enables the process to scale up to commercial production. The purity of the product is above 99.4%.
LPI is fast-tracking the development of Maricunga and has completed it’s Definitive Feasibility Study in January 2019.
The project has the potential for a multi-decade mine life in its currently defined resource to 200m depth, with the possibility for substantial resource expansion in an exploration target at 200-400m depth.
The Project’s Environmental Impact Assessment (EIA) was approved in February 2020. Project financing is targeted in 2020 and the start of construction at the end of Q321.
