LITHIUM: Millennial nears feasibility at Pastos Grandes

ARGENTINA – Millennial Lithium is nearing an updated resource estimate and feasibility study at its 86 km2 Pastos Grandes lithium project in Salta.

The company is aiming for a 25,000-t/y lithium carbonate equivalent operation at Pastos Grandes. It expects to table the study, which will include the updated resource estimate, by the end of 2019’s second quarter.

Millennial is currently drilling the Remsa license at Pastos Grandes to test extensions of its lithium brine bearing aquifer after performing geophysical surveys at Remsa that indicated it had potential for extensions.

The company is about to begin drilling hole 21 on Remsa’s western edge. Results from the hole will go into the forthcoming resource update. It expects to finish the hole early in the first quarter of this year.

The company recently finished building a pilot liming plant at Pastos Grandes. It aims to commission the plant, which will lime brine to reduce magnesium ahead of processing, early in 2019. It’s also developing a pilot processing plant that will produce 3.0 tonnes of lithium carbonate per month, and expects to have it built in about four months.

Millennial expects to submit its environmental impact assessment to the Argentinian government shortly. It expects approval by the end of Q3 2019.

As of a 2017 estimate, the project contains 2.13 million tonnes lithium carbonate equivalent and 8.14 million tonnes potassium carbonate equivalent in the measured and indicated categories.

Shares of Millennial are currently trading at $1.34 with a 52-week range of $1.04 to $4.80. The company has a $110 million market capitalization.
