Technical Report on the Maricunga Lithium Project NI 43-101 (17901 KB)
About the Project
The Maricunga project is located 170 kilometres northeast of Copiapo in the III Region of Atacama in northern Chile at an elevation of 3,800 metres above sea level (masl). The project is comprised of a number of tenements totalling 4,463 hectares.
The project is serviced by a number of access roads and highways capable of supporting the transportation of heavy equipment required for construction and service a mining operation. Additionally, long-term agreements have been entered into for critical project infrastructure including grid power supply and water rights.
Following on from the 2019 Definitive Feasibility Study (DFS), the joint-venture is currently in discussions with strategic parties for off-take and project financing.
The outstanding permits required for construction and operation are anticipated to be finalized in 2020. The Chilean Environmental Review Agency (SEA) awarded the Environmental Impact Assessment (EIA) in February 2020. A key regulatory export license from the Chilean Nuclear Commission (CCHEN) was awarded in 2018 which allows for the extraction, production and marketing of lithium products. A joint venture with CODELCO will provide for remaining permits for new-code concessions and potential for expanded footprint through larger land position.
The Maricunga project represents one of only a small handful of projects at the development stage and the highest-grade undeveloped lithium brine
project in the world. Over US$58 million has been expended on the project to date to advance and de-risk it to its current state.

Maricunga Resource Estimate
Maricunga Reserve Estimate
An exploration target has been identified between a depth of 200 m and 400 m (immediately below the current resource) based on the results of borehole S-19 (TD 360 m) which bottomed in mineralized lithium brine. This exploration target may contain potentially an additional 195,000 to 470,000 tonnes lithium (1.0 to 2.6 million tonnes of lithium carbonate equivalent) and 1.530,000 to 3,470,000 tonnes potassium (3.0 to 6.6 million tonnes of potassium chloride equivalent) between 200 metres and 400 metres depth.
It must be noted that exploration targets are not mineral resources. The potential quantity and grade of the exploration target is conceptual in nature, and there has been insufficient exploration to define a Mineral Resource in the volume where the Exploration Target is outlined. It is uncertain if further exploration drilling will result in the determination of a Mineral Resource in this volume.
The Maricunga Joint-Venture Agreement
Maricunga Joint Venture Ownership Structure
Lithium is considered “strategic” in Chile and therefore it is a non-concessible substance.
Only mining exploitation concessions initiated before 1979 are authorized for the exploitation of lithium. These are referred to as “old code” or grandfathered tenements / claims. The Cocina, San Francisco, Salamina and Despreciada concessions fall into this category.
Lithium production is controlled by the Chilean Government which proceeds on the basis of formal tonnage production quotas assigned by the Chilean Nuclear Energy Commission (CChen). For non-grandfathered claims an additional permit, or Special Lithium Operations Contracts (CEOL), is required.
Recent awards include the Maricunga JV, Codelco, Albemarle and SQM.
