 The key to success as a ground
calcium carbonate supplier is to locate and develop high quality deposits that
consistently offer customers products among the purest and highest brightness
in North America. We continue to explore and search for new deposits to assure
our customers the reliable supply of raw materials for generations to come.
 The Wauconda, Washington Quarry is located about halfway between the towns of
Tonasket and Republic in Northeastern Washington. The area is known as the
Okanogan Highlands and is prized for its excellent fishing and hunting.
Northeast Washington has a rich history of mining, logging, and ranching.
Safety and quality control are the two main priorities at the Wauconda Quarry.
The quarry has five active benches so that stone blending can be performed in
order to achieve constant brightness and CaCO3 content.
 Blast
hole drill fines are carefully evaluated so that the quality of the
stock pile can be controlled. Excavators will occasionally be used to remove
unwanted materials after the blast. The stone is then transported in 30 ton
articulated trucks to the crusher. Shots are never larger than 6,000 tons for
enhanced quality control. Double screening is used to assure removal of small
impurities like clay.
 A telescoping radial stacking conveyer assures that the raw material is
consistently blended onto the stockpile. Trucks are used to transport the raw
material 32 miles from the quarry to our rail loading facility in Janis,
Washington.
CRC's Wauconda, Washington quarry has mineral reserves projected to last more
thatn 200 years. Nonetheless, the identification, exploration and acquisition
of additional mineral reserves with quality and geographic advantages is an
ongoing part of CRC's commitment to its customers.
 The Janis railsite is located 4 miles south of Tonasket on Hwy 97 in the
beautiful Okanogan Valley. The valley is famous for its apple, pear, and cherry
orchards.
The stone received by truck from the Wauconda quarry is stored onto at least two
stockpiles. One of these stockpiles is tarped for use in the winter months,
when road restrictions take effect. As much as 80,000 tons of stone can be
stockpiled at the site.
 Conveyor belts carry the stone from a small receiving hopper to a screening
plant where the material is once more screened to improve quality and purity.
It is then loaded into bottom hopper railcars which are capable of handling up
to 100 tons of material. Each car is carefully and accurately weighed to
ensure
maximum shipping weight and safe use of the railcars.
 Columbia River Carbonates' production facility is located in Woodland,
Washington; a bedroom community situated just 21 miles north of Portland,
Oregon on Interstate-5.
Since its inception more than 23 years ago, Columbia River Carbonates has
committed the resources necessary to assure its customers a reliable source of
ground calcium carbonate powder and slurry products of the highest quality.
Today, the company produces nearly 200,000 tons of product in its $45 million
facility.
