TORONTO, Nov. 19, 2018 (GLOBE NEWSWIRE) — Plateau Energy Metals Inc. (“Plateau” “PLU” or the “Company“)(TSX VENTURE:PLU)(FRANKFURT:QG1)(OTCQB:PLUUF) is pleased to announce new drill results from Falchani West drilling.

• 23 m of 4,412 ppm Li (0.95% Li₂O) from 306 to 329 m downhole (18.8 m true thickness) in lower breccia unit within longest intersection of lithium mineralization drilled to date of 338 m of 2,895 ppm Li (0.62% Li₂O) from 7 to 345 m downhole (277 m true thickness); Li contents up to 5,739 ppm (1.24% Li₂O) (PLAT14-W)
• 90 m of 3,025 ppm Li (0.65% Li₂O) from 84 to 174 m (EOH) downhole (73 m true thickness) in Li-rich tuff unit within a broader 115 m interval of 2,611 ppm Li (0.56% Li₂O) that includes upper breccia unit and tuffs (94 m true thickness) (PLAT13-W)
• Falchani West now has been drill tested 475 m N-S along section within the Falchani West target area and up to approximately 450 m E-W based on drill hole traces projected to surface and the eastern valley edge
• Falchani West has highly anomalous lithium values covering a mapped and sampled footprint of >1.5 km E-W by approximately 1.7km N-S towards Tres Hermanas
• As observed at Falchani East, Lithium mineralization thins to the south due to the presence of a lithium-bearing sub-volcanic felsic intrusion affecting the overlying tuff and breccia units
• Northward towards Platform 14, the lithium mineralization becomes increasingly thick away from the southern intrusion, and is essentially at surface due to its lower elevation and erosion of the barren rhyolite cover rocks
• Three rigs continue to drill at Falchani West towards the West (platforms 32, 33 and 36) and plan to move North through to the end of 2018

“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 sub-volcanic 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.”
