| ABSTRACT: | “Our continued success at Falchani West is encouraging, in particular the presence of a significantly thicker lower breccia unit, as we continue West and North to grow our resource base,” commented Alex Holmes, CEO. “Our project team will continue drilling through to the end of December as we look to incorporate these results into a late Q1 2019 resource update.” Falchani Interpretation Falchani West appears to represent a similar, but potentially larger side of a 6 km by 5 km collapsed caldera with faulting due to the presence of a sub-volcanic felsic intrusion creating an interpreted resurgent dome centred along the N-S faulted valley separating Falchani West area from the Falchani East resource. In the southern drilled extents of both Falchani East and West, lithium mineralization thins to the south due to the presence of this lithium-bearing, sub-volcanic felsic intrusion representing the southern edge of the caldera. The intrusion affects the formation, orientation and preservation of the overlying tuff and breccia units. In the northern drill platforms (example PLAT-14), the lithium-rich tuff unit and to a greater extent, the mineralized lower breccia unit become extremely thick to the north and west from the interpreted resurgent dome intrusion. The lower breccia contains large intersections of Li-rich tuff interpreted as large blocks within the host breccia. The highest grade lithium mineralization encountered to date is located proximal to the base of the thick lower breccia, immediately above the lithium-bearing subvolcanic intrusion. It is interpreted that this sub-volcanic intrusion was a source of heat and lithium-bearing fluids that locally enhanced the lithium contents of the volcano-sedimentary rocks within the collapsed caldera lake. Based on the available data, the Company’s technical team believes the collapsed caldera setting may have trapped the lithium-rich mineralization millions of years ago, during the latest extrusive episode of one of the youngest member of the Macusani rhyolites. The Company’s technical team is working together with its technical advisors to understand more fully this unique volcanic lithium deposit model setting, and research is being considered to unravel the geology and evolution of Falchani. “It appears that we have a very large-scale depositional environment for our lithium project at Falchani. Within a deep and wide caldera lake, several generations of volcanic ash layers were trapped and transformed into the hardened tuff units that we see today,” stated Dr. Laurence Stefan, President & COO. “To date our metallurgical work completed at several laboratories all over the world has determined that the geochemistry of several trace and major elements is mostly similar to a “high-grade” brine, with geotechnical similarities to a hard rock project.” | |
