Mexico & Trump21 Mar 2017 11:05
If I were Kieran i would be searching hard for a good clay deposit in Arizona. Then the 'administrative' address for sourcing lithium from clay would lie wholly within the US. Or there's the MMS route via Nevada perhaps. That has to be the big nightmare hanging over Sonora, How could Tesla source its materials (and be 'politically correct') from Mexico under a Trump regime? Sonora's only outlet looks like Asian offtakers then.
Consider these deposits in Arizona, for instance:
Highlights/Geology - Little Rock
The Little Rock target was first identified serendipitously during a helicopter-borne VTEM electromagnetic survey conducted by Bell Copper Corporation in 2007 while searching for massive copper sulfide deposits. A large, highly electrically conductive body at the south end of the survey area was checked on the ground and found to be a strongly clay-altered rhyolite tuff mostly concealed by a basalt flow.
Geological mapping to the west shows a similar bimodal rhyolite-basalt volcanic association that has been dated between 12 Ma and 8.8 Ma (Late Miocene, Moyer, 1990).
Recognizing that the clay body had potential to be a lithium clay deposit, a reconnaissance sampling campaign was done to understand the extent of the target and the presence, if any, of lithium. Clear evidence was found of a closed, lacustrine paleoenvironment, including thinly bedded rhyolitic claystone and ripple-marked rhyolitic sandstone.
Prior to emplacement of the capping basalt flow, hydrothermal fluid controlled by the basin bounding fault altered the rhyolitic glass to lithium-enriched clay, and then probably discharged into a shallow lakebed. In order to capture the projected basin-bounding fault and the potential volume of hot spring discharge into a closed basin beneath the capping basalt flow, 14 unpatented lode mining claims were staked.
The conceptual dimensions of the target are about 2500 meters along the strike of the basin-bounding fault, about 300 meters perpendicular to the fault, by about 20 meters thick.
Hectorite clay (LR-6) from an active bentonite mine located in the same late Miocene lacustrine and volcanic strata 40 kilometers to the east carries over 2700 ppm lithium.
Timothy Marsh PHD, P. Eng, a qualified person as defined in NI 43-101, prepared the disclosures reports related to the above three projects.
NI-43-101 reports have not been prepared on these properties; and the Company has not verified the geological statements referred to above, which are based on historical data.
