Millennial Lithium (ML.V) has provided another exploration update on its Pastos Grandes The first hole has been completed after reaching a depth of 192 meters, encountering three brine acquifers for a total of 94 meters, with an average density of 1.19-1.22 tonnes per cubic meter, indicating the presence of brine material.
A second hole has been drilled close to the position of the first hole, and reached a depth of 352 meters, with once again several brine aquifers throughout the entire interval with a brine flow of in excess of half a liter per second. The company seems to be really happy with this flow rate, and Iain Scarr, VP Exploration and Development, confirms these exploration results have exceeded the original expectations, even though the final assay results from the first monitoring well will take another 7-10 days.
After seeing the positive flow rates, Millennial Lithium is moving ahead with the installation of a production scale pumping test well, and a larger drill rig has started to drill a test production well to a depth of at least 350 meters. As this will be a ‘real’ test well, the company has elected to drill a hole with a diameter of 15 inches for the first 120 meters, before reducing the diameter to 12 inches at a depth of 120 meters.
