ZURICH, SWITZERLAND / ACCESSWIRE / June 6, 2016 / Today, Stephan Bogner from Rockstone Research published an update on Umbral Energy Corp. (CSE: UMB) as the company provided a significant update on already completed exploration activities, which started on May 19 on the playa of its 100% owned Tule Valley Project in Utah, USA.

Reconnaissance exploration consisted of 1) investigation of distribution of dry lake bed playa vs evaporite, 2) testing/sampling local feeder-springs, 3) wide-spaced "soil" sampling of the playa bed, 4) informative meetings with local BLM (Bureau of Land Managagement) personnel.

The results have confirmed the potential for lithium-bearing brines in aquifers below surface. The company will now focus on geophysical surveying, particularly IP (Induced Polarisation), in order to detect conductive layers beneath the playa as brines are salty (therefore strongly conductive). The thicker and strongest conductive zones, identified by the upcoming IP survey, will subsequently be drill-tested for lithium brines.
