The study was led by GT Ingenieria SA, an independent consultant and started over two years ago.
The hydrogeological model showed that the extraction of brine from the salar will produce minimal impact on the brine level of the salar even under extraction scenarios of 60,000 tonnes of lithium carbonate per year.
The report also found that significant nesting grounds were only found well outside of the proposed mining and operations area of influence.
"We are delighted to have completed this important phase of the project’s environmental evaluation, which together with the previously filed expanded resource estimate, confirms our intention to accelerate the development of 3Q Project," said Waldo Perez, the president and CEO of Neo Lithium.
All the information gathered forms part of the feasibility study for the project which is currently in progress and is also the basis for environmental permit applications.
Updating on operations, the group also said the pilot ponds have been working for more than a year and a half and are now producing high grade concentrated brine of arounmd 4% lithium to feed the pilot plant.
The firm has tripled the evaporation ponds surface this year and will continue building ponds over the next four months to ensure a correct pond infrastructure going forward.
Meanwhile, pilot plant construction is now complete and will start operation and training with Neo Lithium engineers during the fourth quarter and initial sample production is expected to be subsequently transported to Argentina in January 2019.
The plant will have a capacity of 100 tonnes of lithium carbonate per year, however the plant is expected to operate in batches to maximize the process and obtain final data for the feasibility study.
