Elcora Advanced Materials Corp. announced completion of the first phase of vanadinite comminution testing. The purpose of these tests was to characterize the mineral suite found within the deposit economic rocks and
determine the liberation sizes to direct later comminution studies. Two samples were tested. Both were composed of porous rocks and loose material. Three investigative tools were undertaken to determine these values: optical and electron microscopy and whole rock assay using ICP. The loose materials, composing approximately 12.5% of the sample. The economic mineral contained within the sample are the vanadium/lead/chloride vanadinite. Primary
gangue minerals are silica, and calcite/dolomite. The ICP information indicates a vanadinite content of 66% of the entire sample whereas the microscopy indicates 62.9% (including the loose materials). ICP indicates minimal volumes of other minerals, other than silica or silicates, with some mica, that occur in cemented zones between the vanadinite crystals. Inclusions within the vanadinite were identified as silica. The CIP whole rock analysis of the samples tested, shown in Table 2, indicates an 8.9% vanadium grade within the vanadinite and associated cementation zones.
