Mining/Custom Landscape Materials


The company began production of decorative landscape boulders from its Big Horn quarry under the name of Custom Boulders in July of 1995. A crushing and screening plant was purchased the following year to also produce decorative gravels. In July 1998, the company changed its name to Custom Landscape Materials, L.L.C. to more accurately reflect the nature of its business. On September 5, 2002 West Valley Rock was opened in Buckeye, to provide for the needs of the West Valley consumer. In April 2003 the Belmont Granite quarry began production of “Desert Granite” decorative rock along with State and Mag Spec aggregates. During January of 2005, Fancy Concrete started supplying colored and grey concrete to the local west Maricopa county market. Our latest addition to our product line was the acquisition of a “Redi-Rock” franchise in March 2007 by West Valley Precast.

Property and Location

Custom Landscape Materials’ “Big Horn” property consists of 10 patented mining claims, comprising approximately 209 acres. It is located 80 miles west of downtown Phoenix, north of I-10 about 40 miles about halfway between Aquila and Wickenburg on the Aquila road. (Location Map Attached) The property lies on the North Slope of the eastern Big Horn Mountains in an area of intense geological deformation and alteration. It is the site of a previously mined gold deposit which is the source of the alteration in the immediate area leading to the various coloration’s of the host rocks for the 6 different gravel colors produced at the site.

Custom Landscape Materials’ “Belmont” property consists of B.L.M. mining claims, comprising approximately 100 acres. It is located 60 miles west of downtown Phoenix, north of I-10 about 20 miles on the Wickenburg, Vulture Mine road. (Location Map Attached) The Belmont property is located at the north end of the Belmont Mountains a granitic intrusion. The production of homogeneous light colored granite in all sizes, as well as the harvesting of surface eroded boulders occurs at this site. West Valley Rock, Fancy Concrete And West Valley Precast are all located on a 29 acre parcel northwest of I-10 & Miller Road in Buckeye. The location was chosen for the freeway access and visibility. The central location of the west Maricopa county future development expected over the next decade was also a determining factor of this location.

Production Capacity

Custom Landscape Materials operates a crushing and screening plant at all its Big Horn Pit, Belmont Pit. Capable of producing more than 5000 tons of gravel per day. In addition pit support equipment consisting of eight 6 to 8 yard loaders, 4 smaller front end loaders, 3 excavators, 2 loader backhoes, 5 water trucks, 28 haul trucks, bulldozers, drills, and a complete shop and repair facility are used at each pit in the production process. The company also produces many sizes of riprap ( 1-5”, 3-8”, 8-12”,12”-24”) plus boulders in each of the 12 colors produced. Reserves The Big Horn quarry of Custom Landscape Materials are situated on 10 patented mining claims of approximately 209 acres. Virtually almost the entire property is mineable and hosts rock formations within the six colors being produced at the present time.

  • Arizona Blonde - Pink
  • Desert Spice - Tan with purple green highlights
  • Desert Tan - Light tan
  • Saddleback Brown - Dark brown
  • Jesse Red - Dark red / maroon
  • Sundance Blend - multi-colored

Although a tonnage estimate of reserves is not feasible, the company expects sufficient reserves are available at current production rates for several decades.

The Belmont quarry is situated on a large granitic intrusion. The current outcrop that is being mined is approximately 3 to 5 million cubic yards in size. The potential mining area is approximately 100 times larger on adjacent outcrops of the same granitic material.


All of the gravel produced at the company’s Big Horn quarry is a variably silicified rhyolite or andesite. The rock having a hardness of 14% abrasion loss @ 500 revolutions, based on Los Angeles Abrasion Tests, ASTM C131. (Results available)
