The company overseeing the Horse Creek Rock Quarry northwest of Cheyenne is looking to expand its operations by 585 acres — a plan that was recently announced via letter to nearby landowners.

L.G. Everist Inc. (LGE), a construction material company based in Sioux Falls, South Dakota, owns the existing Horse Creek Rock Quarry, a mine located 31 miles northwest of Cheyenne at 3380 Horse Creek Road.

LGE sent a letter to nearby landowners stating its intention to submit an application for a conditional use permit — class C to expand operation of the mine from a limited mining operation on 15 acres to a large mining operation on 600 acres.

LGE secured its limited mining operation permit in 2023, and production began in 2024.

The mine, which is located along the BNSF Railway mainline, taps into a granite deposit and supplies materials to customers across Wyoming, Nebraska, and northern Colorado.

The mined granite will be crushed and processed on site, then hauled in trucks via Highway 211 to Cheyenne and northern Colorado.

The mine is also located in close proximity to the proposed Laramie Range Wind Farm, which is still in the permitting and approval process.

Matt Noteboom, vice president of LGE’s Mountain Division, said LGE officials made the decision to expand in order to have access to additional reserves.

Noteboom said this decision was only made recently, and was not the plan from the beginning.

“This is relatively new. When we first got the original 15-acre permit, we weren’t sure which direction this quarry was going to go,” Noteboom said.

The 15-acre quarry is situated completely on Farthing Ranch Co. property, owned by Charles Farthing. If the expansion goes forward as planned, Noteboom said it will still be located 100 percent on Farthing property.

“That 600 acres won’t all be mine. That will encompass the roads, all the plant sites, places where they park the equipment. The actual mining permit will be as far as where they’re digging, which will be 200 acres,” Farthing said.

According to the quarry concept plan, the expanded site would be developed in phases until final reclamation is completed in the year 2090.

The initial development phase, which is slated to occur from April 2027 to April 2028, includes commencing primary mining operations on the North Hill deposit, and establishing a new starter pit south of the existing processing plant site.

Development and use of the North Hill Pit would continue until approximately 2059, which is when depletion and reclamation of the pit would begin.

In 2053, LGE would begin switching operations to its South Hill Pit development, which would remain active until approximately 2089.

The North Hill and South Hill pits would be operational concurrently from 2053-59.

The expansion is still in the very early stages of planning, Noteboom said. LGE has not applied for any permits yet, and is in the discussion phase with the Wyoming Department of Environmental Quality and the Laramie County Board of County Commissioners.

The Laramie County Planning Commission will hold a public hearing on the permit application at the Historic Courthouse in Suite 310 on March 26 at 3:30 p.m. County commissioners will hold another public hearing regarding the application April 21 at the same place and time.
