    MUDDY MOUNTAIN PROJECT

    ‘The Muddy Mountain Lithium Project was also visited and the target formation, the Horse Spring Formation, was located within the leases. This formation has previously reported lithium assays of up to 5,000ppm (0.5%) lithium derived from the contained mineral hectorite.
    Inspection of the claims has shown beyond doubt that the Muddy Mountain claims have the potential to define a multi-million tonne lithium resource grading in the range 0.3% to 0.5% lithium. Several samples of the formation were taken, results of which will be reported as soon as available. Project infrastructure is fair with the project being situated less than 40 kms northeast of the city of Las Vegas.’

    Beyond doubt is a big call by CAD but I have spent many hours doing my own due diligence on this tenement and I would have to agree BEYOND MY OWN DOUBT that muddy mountain is a company maker.

    GEOCHEMISTRY OF MUDDY THE MUDDY MOUNTAIN AREA:
    The results of spectrographic and atomic-absorption analyses of 135 stream-sediment samples taken
    from within the WSA boundary (Bohannon and Vine, 1982) indicate no significant enrichment in metals, other than lithium. Arsenic, gold, bismuth, cadmium, antimony, tin, tungsten, zinc, and thorium were not detected in any of the samples by either analytic


    MINERAL RESOURCE POTENTIAL
    The Muddy Mountains WSA has a high potential for borate minerals, lithium, and the clays associated
    with them, a moderate to high potential for zeolite minerals, and possibly some oil and gas potential.
    There is apparently little potential for metals other than lithium.
    Mineral Potential Borate minerals are confined to the lower part of the Lovell Wash Member and in some places to the uppermost beds of the Bitter Ridge Limestone Member of the Horse Spring Formation. This part of the stratigraphic section is exposed within the boundary of the WSA in the southern and western parts of White Basin and in the Lovell Wash area (fig. 4). It also occurs within the WSA in the shallow subsurface of western

    White Basin beneath the red sandstone unit. Although nearly all of the production of borate minerals took place just outside, or right on, the WSA boundary, any exposure of the Lovell Wash or uppermost Bitter Ridge Limestone Members is considered herein as a potential source for calcium borate minerals. Apparently, the chief controlling factor that localized mineralization was syndepositional spring activity (Bohannon,
    198Za).
    Ancient centers of spring activity are common in this part of the stratigraphic section, and there is a
    high potential
    . for undiscovered centers of mineralization
    Borate resources at the Anniversary Mine are an estimated 380,000 tons (345,000 t) of low-grade
    reserves and about Z,OOO,OOO tons (1,800,000 t) of inferred reserves averaging 15-ZO percent Bz03•
    Because underground workings were inaccessible, data are insufficient to make estimates for the American Borax Mine in White Basin.
    Reconnaissance sampling and analysis for lithium within the Horse Spring Formation in the Muddy
    Mountainsarea (Bohannon and Meier, 1976; BrennerTourtelot and Glanzman, 1978; and Brenner-Tourtelot, 1979) and similar detailed sampling of the Lovell Wash
    and uppermost Bitter Ridge Limestone Mem hers of that formation in the WSA by the U.S. Geological
    Survey (Bohannon and Vine, 198 Z) and the U.S. Bureau of Mines indicate that the Lovell Wash and upper Bitter Ridge Limestone Members are highly enriched in lithium. The regional reconnaissance sampling
    indicates that other members of the Horse Spring Formation have only limited lithium enrichment in the
    vicinity of the WSA. Lithium content from 18Z samples from the Lovell Wash and uppermost Bitter
    Ridge Limestone Members ranges from 78-2,040 ppm and, of these, only 4 samples have values below ZOO
    ppm. Vine (1980, fig. 4, p. 64a) ranked potential lithium resources in rocks and sediments and suggested that any deposit having a thickness on the order of that of the Lovell Wash Member and average concentrations of 300-1,000 ppm lithium "warrants further search" for lithium resources. He further concluded that a deposit 30 ft (9 m) thick containing concentrations between 1,000 and 3,000 ppm constitutes a "major resource potential." Because the detailed sampling program indicates that beds having lithium contents greater than 1,000 ppm are abundant in the Lovell Wash and uppermost Bitter Ridge Limestone Members, these units are considered herein as having major lithium resource potential, and they are shown so on figure 4. As in the case of borate minerals, a similar potential for lithium minerals exists in the subsurface of western White Basin.
    The lithium values in the Lovell Wash and upper part of the Bitter Ridge (note on historic map below) Limestone Members are anomalously high compared with values reported from other similar deposits in
    other parts of the Basin and Range, and they are
    considerably higher than the backgrot.md lithium values of the southern Nevada region (Bohannon and Meier,
    1976). Techniques for the effective extraction of lithium from sediments and sedimentary rocks are not available to the lithium industry at
    ·present. Nonetheless, future demands on the lithium industry may warrant consideration of the Lovell Wash and uppermost Bitter Ridge Limestone Members within the WSA as targets for lithium exploration and possible production someday.
