Surface clay deposits known as the “White Hills” were initially discovered in the mid-1950’s and were known to contain bentonite and hectorite clays. Exploration data from the 1960’s shows that lithium contents of clays near the White Hills range from 0.03 to 0.53% Li2O (140 to 2,460 ppm Li) (source: Lithium-bearing Bentonite Deposit, Yavapai County, Arizona, Geological Survey Research, 1965, Chapter C, by J.J. Norton).  Sampling was done by a variety of methods at the time including trench sampling, sampling of drill hole cuttings, sampling of an open pit, sampling of a prospect pit, and sampling of an outcrop. This sampling was done before the implementation of NI 43-101 or CIM Mineral Exploration Best Practices Guidelines and the results have not been verified by a Qualified Person.  Ameriwest is treating this data as historical, and  but it shows the potential for lithium on the Property in the region.

One of Ameriwest Lithium’s newest acquisitionS, Thompson Valley,  is a prospective lithium sedimentary deposit with surface or near-surface exposure of lithium-bearing clays, with historic grades similar to those found in Nevada claystone deposits.

  • Ameriwest has been awarded 13 exploration permits by the Arizona State Land Department to explore for prospective lithium-bearing clays located on nearly 6,270 acres in west-central Arizona’s Thompson Valley.  In addition, Ameriwest has staked 33 federal mineral claims totaling about 620 acres, for a total property size of 6,890 acres.
  • The location has good access and is not far from State Highway 93, 120 miles (190 km) north of Phoenix. 
  • The deposits are shallow, occurring at or near the surface, and it has been reported that the overall clay sequence is 70 feet (21 m) thick, containing a hectorite bed with a thickness ranging from 8 to 35 feet (2.4 to 11 m) as a relatively uniform deposit over the area.
  • Ameriwest has completed geological mapping and initial surface sampling.
  • Assay results from 44 surface grab samples, analyzed by Paragon Geochemical (“Paragon”) in Sparks, Nevada, show lithium contents ranging from 15 to 1,670 ppm Li. From the 44 samples submitted for assaying, 27% had lithium contents greater than 500 ppm, and 9% were greater than 1,000 ppm with a mean of 353 ppm Li and standard deviation of 406 ppm Li (see press release dated August 10, 2022).
