Detailed geological mapping has shown that the marble varies from fine-grained yellow and green to a coarse grained white rock. Reserves in the three deposits mapped amount to 18,500 tons, but only about 20% of this is suitable for slabs because of closely spaced jointing. The marble masses are irregular in shape, but comprise part of a persistent calc-silicate formation. Nephritic jade is confined to the calc-silicate zone, and occurs on the margins of the marble masses. Gem quality material appears to be related to weathering at the ground surface.
