Millennial Lithium Corp. reports posi- tive analytical results from its first two complete exploration wells at the Pastos Grandes Project in Salta, Argentina. Exploration holes PGMW1601 and PGMW1602, drilled vertically to depths of 355 and 400 metres, respectively, in the Northern portion of the salar, ended in brine bearing formations and confirm that the salar’s brine carrying capacity extends to much greater depths than encountered in previous exploration. Exploration holes PGMW1601 and PGMW1602 were collared over 1.5 kilometres (km) apart and both encountered thick sequences of loose, brine-bearing sedi-ments. Both holes were terminated in brine bearing formations at depths greater than antic-ipated. Depth specific brine samples were collected at various intervals from both holes using drive-point and packer systems designed to isolate sample intervals. Nine brine samples collected from exploration hole PGMW1601, from surface to 355 metres, contain an average lithium grade of 395 milligrams per litre (mg/L) and an average magnesium/lithium ratio of 6.2. Individual lithium grades from the hole range from a low of 297 mg/L to a high of 471 mg/L. Ten brine samples collected from exploration hole PGMW1602, from 71 to 400 me-tres, contain an average lithium grade of 389 mg/L and an average magnesium/lithium ratio of 6.1. Individual samples from this hole range from 339 mg/L to 399 mg/L lithium. Average grades of these first two holes in the Northern section, are significantly higher than the re-sults reported in historical drilling. Eramine SA, reported results from historical drilling which averaged a lithium grade of 331 mg/L to a depth of 125 metres. Phase I drilling has been confined to the Northern portion of the salar while property negoti-ations to expand the southern land package were ongoing. Future drilling will include the Southern end of the salar where lith-ium values are expected to be higher. Two historical holes drilled by Eramine SA in 2011, in the southern portion of Pastos Grandes returned average lithium grades of 558 mg/L and 566 mg/L, significantly higher than Eramine drill holes in the Northern portion. Preliminary tests indicate a capacity for high flow rates. Field crews successfully constructed and developed a production-scale well, PGPW1601. Pre-testing of the well, comprising pumping at rates of up to the maximum rate for the pump used, 23 liters per second (L/s), resulted in a draw-down of just 11 metres below the static level. While preliminary, at a specific drawdown of only 0.5 meters per liter-second, this is a very positive indication of the pumping capacity for wells at Pastos Grandes. In addition to results from the pumping well, PGPW1601, flow testing during packer testing of all but one zones in the exploration wells resulted in brine flows exceeding 0.5L/s. Results indicate that brine impurities improve with depth as confirmed by a decreasing magnesium to lithium ratio. Near surface chemistry in the 6 to 8:1 range (Mg:Li) decreases to below 6:1 at depth (Mg:Li). Observations and preliminary analysis from Millennial’s tech-nical advisory board indicates that the sulphate content is well matched to counter calcium and magnesium in the brine and that a majority of these impurities can be reduced in an evaporation process. Conventional processing, as envisioned for Pastos Grandes, will also recover potash. Pumping tests and drilling, currently on hold due to the onset of summer rains, will resume in early March 2017.
