The Porc property covers a series of knobs of medium to coarse-grained syenite to granite of the Eocene Coryell Plutonic Suite. The showing area is accessible via the Bulldog Mountain Forest Service Road.

Two dominant rocks types were located, distinguished primarily by grain size. The coarser grained stone is a dull pink syenite to granite. The composition is 2-5 per cent mafics (hornblende and biotite), 5 per cent 5-10 millimetre smokey quartz eyes, 10-20 per cent anhedral, white to clear plagioclase, and 60-80 per cent pink to brown anhedral K-feldspar. This stone has a "dull" lustre due to chlorite in concentrations to 10 per cent. The K-feldspar also shows a "yellowing" around its rims, which gives the stone a faded look. A medium grained pink syenite to granite is a much more appealing stone. The overall composition is somewhat similar to the coarse-grained stone, except for a 5-10 per cent increase in plagioclase at the expense of K-feldspar. The plagioclase crystals reflect the light giving the

stone a weak "liveliness". The medium-grained stone is from the talus below a large knob of syenite in excess of 100 by 50 metres. This knob has an associated talus slope where 15 per cent of the talus is in excess of 1 metre. The percentage of +1 metre blocks lying in the talus suggest large blocks should be obtainable.

The initial prospecting and mapping of the Porc property in 1993 by R.T. Henneberry has located two distinct phases of the same syenite: a coarser grained and a medium grained dull pink syenite. These stones have a known world comparison in the Italian stone "Amarello Paraiso A".
