Item 5 Full Description of Material Change

The Company announced the initiation of a geophysical survey at its Railroad Valley property in Nevada.

Ameriwest’s Railroad project encompasses 6,240 acres for total of 312 placer claims just 200km to the northeast of the highly productive Clayton Valley. While Railroad Valley offers certain geological similarities to Clayton Valley, it differs in that it represents a new and virtually unexplored target, with only a handful of companies present, unlike Clayton Valley’s numerous leases and complex water issues which are fragmented across many competing companies. Within Ameriwest’s project area at Railroad Vally there appears to be a convergence of factors favorable for lithium brine formation, including a deep hydrological reservoir covered by an evaporative playa.

Ameriwest’s geophysical survey is designed to determine the presence and depth of conductive and potentially lithium brine-bearing strata. The work will include a 12.0 line-kilometer Magnetotelluric (“MT”) geophysical survey undertaken by Zonge International Inc. (http://zonge.com), a respected geophysical services and equipment provider for exploration, research, geotechnical and environmental engineering worldwide.

The survey will consist of two MT profiles across the property to provide data which will ultimately help define a drill program on the property, subject to exploratory success. Magnetotellurics (MT) is a naturalsource electromagnetic geophysical technique that measures the resistivity of the subsurface. MT is uniquely suited for either very deep exploration purposes or for exploration in extremely conductive terrains. Lithium brines are, by their nature, very conductive and are a good target for MT applications.
