SAND, GRAVEL & QUARRY ROCK

Sand, gravel and quarry rock are significant components of the subsurface estate that Calista Corporation received through ANCSA. These materials generate corporate revenue through sales for commercial and residential development and through grant-funded and capital-funded projects.

Upgrading rural airstrips to meet FAA safety standards and federal funding for transportation projects in Alaska communities provide a continuing demand for sand, gravel and rock. Runway lengthening, widening or relocation requires both embankment and surfacing materials which can be sourced within the Region. Other community infrastructure projects require construction materials to build village water and sewer systems, access roads and docks. Overall regional population growth and the resulting need for additional housing and other facilities increase the demand for sand and gravel for embankments and foundations.

The Nunalista Joint Venture between Calista Corporation and Knik Construction manages several key material extraction sites in the Region, including the Kalskag, Platinum and Goodnews Bay rock quarries, and the Aniak and Platinum gravel pits. These road and barge accessible sites provide several varieties of construction material to the growing Bethel market as well as other villages along the Kuskokwim River and Delta. The Kalskag, Goodnews and Platinum quarries furnish a more durable, high-quality crushed aggregate product that is suitable for road surfacing and airstrip surface courses.

Sand, gravel and crushed rock provide economic resources to communities in the Calista Region through surface disturbance payments to ANCSA village corporations, and Shareholder employment during extraction, hauling, shipping and placement of materials used in local construction projects.
