Hi Rick,

    Most of the tests of "white buffalo" that I have heard of came back
    as alunite or howlite as you have stated. 

    The Manual of Mineralogy that I am referring to is a standard
    college text after Dana. Chalcosiderite is mentioned in the section
    about the turquoise group, but is not, as you have stated, turquoise. 


    In my opinion, chalcosiderite is not turquoise, it is a separate
    mineral. I am going to collect samples from my claims that come from
    turquoise producing veins and appear white. I have never marketed any
    material as white turquoise (and really don't care to) but I am
    continuously curious about what I find in the field. 

    Finally, about those "clams". I recovered some in the '90's while
    digging variscite in Nevada. Some of them were incredible green with
    black spiderweb. We always considered them to be phosphate
    concretions rather than replacement fossil formations. Have you been
    able to find out who determined them to be clams? Maybe someone at NM
    Tech? These things have become quite collectible lately but I am
    reluctant to sell any as "clams" until I know for sure. They sure are
    cool though.
