Quarry work to resume north of Glenwood


GLENWOOD SPRINGS, Colo. – CalX Minerals, LLC, has notified the Bureau of Land Management its intent to conduct quarry work at the Mid-Continent Quarry above Glenwood Springs later this month or in July.

CalX Minerals, a Denver-based company, recently purchased from Pitkin Iron the mining claims and mining permit for the quarry, which is along Transfer Trail. They plan to quarry rock dust, which will be used in regional coal mining operations. Although the quarry has been inactive for the past several years, it has been in operation since the 1950s.

“Mining operations have been authorized by BLM and the State of Colorado on this claim for several decades,” said Glenwood Springs Field Manager Steve Bennett. “Since operations will continue to be confined to the permitted area, no new permits or authorizations are required from BLM for operations to begin.”

Operations will consist of quarrying and grinding rock onsite. All grinding will occur indoors 24-hours-a-day. Mining, crushing and screening will be limited to 7 a.m. to 5 p.m. Monday through Friday. Some blasting will occur between April and December each year, averaging about one blast a month. CalX does not expect the blasting to generate much noise or vibrations. Blasts will be closely monitored by CalX to ensure vibration control.

CalX expects associated truck traffic to be about 20 roundtrips each day. They will provide dust abatement and road maintenance, as well as sign the road and work with the community and other agencies to ensure winter recreationists continue to have safe winter access.

“Because this quarry is located relatively near several regional coal mines, we expect truck trips to the coal mines will be reduced by 1.2 million truck miles per year,” said Ben Miller of CalX. “This would reduce the amount of CO2 emissions by 9.8 million pounds each year.”

Mill facilities will be located onsite and will be designed to contain the majority of noise and dust produced during grinding. There will be two to four grinders with one to four adjacent silos. Facilities will be located behind an existing ridgeline and painted a BLM-approved color to help reduce visual impacts.

“We are looking forward to beginning operations in the Glenwood area and are committed to keeping impacts to the local community to a minimum,” Miller said. For additional questions, please call Ben Miller at 303 761-4770.
