Item 5 Full Description of Material Change

5.1 Full Description of Material Change

The Company announced that it had staked 312 unpatented placer claims, totalling 6,200 acres, in Railroad Valley, Nevada (the “ Valley ”). The claims, known as the Railroad Lithium Property (“ Railroad ” or the “ Property ”), are located 100 miles northeast of Tonopah. Ameriwest management believes that the Property has the potential to host lithium brine deposits that, subject to exploration success, have similar characteristics to deposits found in the Clayton Valley. In this respect we note that North America’s only producing lithium mine, owned by Albemarle Corporation ( NYSE:ALB ), has been in production in Clayton Valley since 1966.

The Valley was originally identified by the US Geological Survey (“ USGS ”) as having potential to host lithium bearing brines in its subterranean aquifers beneath the valley floor. The Valley fits the current geological model and understanding of lithium brine deposit occurrences, (as defined by USGS Open File 2013-1006), and is considered analogous to Clayton Valley. Based on the seismic surveys, the Valley is about three times the size of Clayton Valley. It is a closed, arid basin with a high evapotranspiration environment. It also encompasses numerous lakes following the glacial periods that filled the basin and evaporated. The Valley is a classic Basin and Range down-dropped graben that has been infilling with sediments for over 20 million years and has comprised a total thickness reaching up to 2,900 meters in depth.

Ameriwest’s COO, Glenn Collick, commented “We have been working hard to establish Ameriwest as a key lithium exploration company. We are extremely pleased to announce the

completion of the staking of Railroad. It will further add to our lithium property portfolio, alongside our Deer Musk East Property located in Clayton Valley. Deer Musk East is located just five miles from Albermarle’s Silver Peak Lithium Mine and also has potential for the discovery of lithium brine deposits.”
