Aggregate Mining

K&M Mining is proud to own and operate our mines and quarries for the benefit of our construction projects as well as those of other construction companies throughout the tri-state area who need high-quality aggregate. Scoria, limestone aggregate, and gravel are among some of the most-consumed raw materials in construction projects ranging from highways to wind farms and from interstate pipelines to local facilities. Our mines produce all three to our customer’s exact specifications in the quantities needed to ensure all projects are finished on time and on budget. Operating our own mines means tailoring our aggregate production process to precisely meet our needs as well as our customer’s needs. Regardless of the scope of your project, we can ensure raw materials are always available at any location throughout Wyoming, North Dakota, and Montana. Cutting out the middleman and reducing the number of contracts needed for the project meets a streamlined process and quality-control through every step.
