Plateau Energy Metals Continues to Expand Falchani Lithium Deposit

TORONTO, Jan. 30, 2019 - Plateau Energy Metals Inc. (“Plateau” or the "Company") (TSX VENTURE:PLU) (OTCQB:PLUUF) is pleased to announce, as part of the Company’s ongoing drilling program to expand the mineral resource at its high-grade hard rock Falchani lithium project, the latest drill results from four holes at Falchani West, and three new drill holes results from Falchani East.

Falchani West Highlights

Refer to Figure 1 - Falchani Lithium Project Drill Plan Location Map

• 200 m of 2,519 ppm Li (0.54% Li₂O equivalent(eq)) from 117 to 317 m downhole in thin upper breccia, lithium-rich tuff and lower breccia; includes a thick 156 m lower breccia intersection averaging 2,624 ppm Li (0.57% Li₂Oeq) from 161 to 317 m, with Li contents up to 4,862 ppm (1.05% Li₂Oeq) (PLAT33-V)
• 17 m of 3,728 ppm Li (0.80% Li₂Oeq) from 28 to 45 m downhole in Li-rich tuff within a broader 56 m interval of 2,420 ppm Li (0.52% Li₂Oeq) that includes upper breccia unit, Li-rich tuffs and lower breccia unit from 18 to 73.5 m (End of hole - EOH) (PLAT36-V); hole terminated in mineralization due to ground conditions
• 14 m of 2,685 ppm Li (0.58% Li₂Oeq) from 24 to 38 m downhole in Li-rich tuff within a broader 53 m interval of 2,521 ppm Li (0.54% Li₂Oeq) that includes upper breccia unit, Li-rich tuffs and lower breccia unit from 15 to 68 m (PLAT32-V)
• 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 ridges with outcrop trenching and sampling results pending
• Drilling continued to the end of December 2018 with 4 additional drill hole results pending
• Three rigs will restart in 2019 and will continue to expand drill coverage at Falchani West to the west and north to be incorporate in the resource update targeted for late Q1 2019
• Preliminary leach results from the upper and lower breccia units suggests that the breccia mineralization behaves similar to the better studied, Li-rich tuff unit; similar extraction, leach and processing routes are expected

Falchani East Highlights

• Platform 1 drilling has now established true thickness of lithium mineralization at the discovery hole
• 112 m of 3,816 ppm Li (0.82% Li₂Oeq) from 76 to 188 m downhole (91.7 m true thickness) in lithium-rich tuff unit within a broader interval of 153 m of 3,182 ppm Li (0.69% Li₂Oeq) from 59 to 212 m downhole (125.3 m true thickness) in thin upper breccia, lithium-rich tuff and lower breccia (PLAT1-SSW)

“These results continue to demonstrate similar grades and widths in the lithium rich tuff unit at the interpreted southern fringe of the collapsed caldera, and we are seeing a significantly thicker lower breccia unit as compared to Falchani East” commented Alex Holmes, CEO of Plateau. “Our exploration team will focus on a few more holes at Falchani West targeted to put together a maiden resource as part of the Q1 2019 resource update.”

Falchani Interpretation

The geological interpretation at Falchani West continues to evolve. 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 a volcano-sedimentary explosive diatreme unit that marks the commencement of volcanic activity at Falchani. The diatreme unit overlies the lithium-bearing sub-volcanic intrusion, interpreted to be 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.

The original radioactive prospecting discovery at Falchani East has been tested by drilling over only ~25-35% of the original ~2km² surface area. The surface uranium mineralization remains a future target for additional drilling to the north and east of the Falchani East lithium resource area.
