The Evans Lou pegmaitite was originally mined from 1939 to 1952 for feldspar, when 25,000 tons were mined. It was mined later for silica when a 20x40 mass wwas mined. A lot of the Rare Earth minerals were thought to come from this quartz mass or near the ...
www.mindat.org/gm/922An attractive aggregate of white caysichite-(Y) crystals ~1 cm long, perched on smoky quartz. This is probably the best specimen and largest crystals known for the species. The specimen is estimated to be 7 cm high and it is in the collection of the Freiberg Bergacademie Museum in Germany. Photographed in the display case through the glass.
www.dakotamatrix.com/products/11457/caysichite-yCaysichite-(Y) - The crystals were difficult to photograph, but the flat portion of matrix is covered with tiny, white acicular crystals less than 0.25mm in size. There is one small open space in which hundreds of free-standing needles occur. It was tested by EDS by a Harvard professor at one time. . This and many more mineral specimens are available for sale at Dakota Matrix Minerals.
