Galan Lithium (ASX:GLN) said that the nanofiltration plant was delivered to the Hombre Muerto West project site in Argentina and that overall construction of the first phase at the project is around 85% complete, according to a Monday Australian bourse filing.

Over the past two years, the firm has accumulated a lithium brine inventory of around 9,500 tonnes of lithium carbonate-equivalent in the project's ponds, Galan's managing director, Juan Pablo Vargas de la Vega, said. The assembly and commissioning of the nanofiltration plant will allow the firm to produce processed lithium brine.

It completed the construction of the sylvinite ponds, designed to accelerate the evaporation of processed brine, required for the start of the first phase operations.

The firm's shares rose 1% in recent trading on Monday.
