The Pacific Rose prospect is located about 31 kilometres west of Summerland.
This site is located in medium to coarse-grained pink and white granite of the Middle Jurassic Pennask batholith. Granite outcrops form an elongate, east-west oriented ridge with bare rock ledges, faces and a granite boulder field on the lower part of the slope. The great size of the boulders and massive outcrops indicates low fracture density. The rock is homogeneous with only occasional dark inclusions.
In 1992 and 1993, Pacific Granistone Ltd. optioned this site and produced a number of blocks which were processed into facing-stone sheets. Under the trade name Pacific Rose granite, this stone was used as floor tile and outside facing in the Jack Davis Building in Victoria. This structure houses the former B.C. Ministry of Energy, Mines and Petroleum Resources, recently amalgamated into the B.C. Ministry of Employment and Investment.
Pacific Rose stone is an attractive medium to coarse grained, pink two-feldspar granite. Major constituents are pink orthoclase, white plagioclase, glassy grey quartz and greenish white microcline. Minor minerals are sphene, apatite, rutile, biotite and magnetite (1-2 per cent). Microcline imparts a faint greenish cast to the otherwise white matrix. The texture and colour are uniform with no fabric present.
The rock is quite fresh with minor sericitization of plagioclase and no alteration of biotite. The rock takes a very good polish (8-9/10) with no iron staining. Grains are well interlocked but there is a lot of intergranular cracking. Some minor pitting occurs on biotite grains or on feldspars where cleavage intersects intragranular cracks.
