TULE VALLEY LITHIUM EXPLORATION PROGRAM UPDATE
Umbral Energy Corp. has provided this update on the Tule Valley lithium exploration project. The property is 4,800 acres and is located approximately 190 kilometres southwest of Salt Lake City, Utah, and is accessible by an all-weather road from Delta, Utah.
A reconnaissance survey of the property consisted of:
Investigation of distribution of dry-lake-bed playa versus evaporite; Testing/sampling local feeder springs; Wide-spaced soil sampling of the playa bed; Informative meetings with local U.S. Bureau of Land Management personnel. The Tule Valley playa is a dry lake bed, mostly covered with a thin layer of wind-blown sand, with several active evaporite ponds, where leakage from nearby springs brings water onto the low-lying areas of the playa, thereby producing active evaporation. Composed of dried mud/silt/ash, the compacted playa mud is salty (indicating some form of evaporation from either surface water or groundwater during the life of the playa) and displays gypsum crystals (calcium sulphate; indicating the introduction of sulphate during the drying/evaporation process, which in turn suggests some form of groundwater influence). The Tule Valley playa is a closed valley, has lithium source rocks located several kilometres north of the property (see May 19, 2016, news release), has active groundwater flow along its western margin and has been affected by evaporite-style processes. Tule Valley may therefore be conducive to the presence of lithium-bearing groundwater.
In this respect, Tule Valley has similar characteristics to Clayton Valley, Nevada, a dry lake bed where lithium is derived from brines located within more porous sediment layers at depth under the playa. The Tule Valley exploration will focus initially on geophysical surveying, particularly induced polarization, to detect conductive layers beneath the playa. Brines are salty and are therefore strongly conductive. The thicker and strongest conductive zones will subsequently be drill tested for lithium content.
Jag Bal, president of Umbral, commented: "Our company is focused on evaluating the potential for development of lithium in Utah and Nevada. The lithium industry is growing very quickly, and Umbral is eager to be part of this. We strongly believe in the properties we have acquired and we are looking forward to further exploration on our Tule Valley project."
