Atacama Region, Chile
PEA 4Q17, Feasibility Study 2Q18
2.15Mt LCE at 1,160 mg/l & 5.7 Mt KCI at 8,500 mg/l
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 2017 JORC and NI 43-101 compliant resource estimate for the deposit totals 2.15 Mt LCE & 5.7 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 (complete details are provided in resource tables and technical reports).
The Maricunga Virtual Mine Site Tour provides an in-depth view and main stages of the milestones so far achieved
LPI is fast-tracking the development of Maricunga. Submission of the Environmental Impact Assessment (“EIA”) is targeted for 1Q18, followed by a definitive feasibility study (“FS”) targeted for completion in 2Q18.
A lithium carbonate (“Li2CO3”) and potassium chloride (“KCl”) process flow sheet has been defined and pilot plant optimisation for Li2CO3 production is ongoing. Test work has successfully achieved a 5% lithium concentration and the first Li2CO3 and KCl production samples are expected by the end of 2017. Port and logistics assessments are fully completed.
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.
Permitting and government approvals are expected by 2Q19, at which time LPI will make a production decision. Project financing and start of construction are targeted to follow in 2019.
