Extracting premium-quality raw stone and aggregate materials from certified geological reserves using modern precision methods.
Advanced multi-stage crushing plants processing raw materials into precise, multi-fraction custom sizes for heavy industrial projects.
Rigorous laboratory analysis guaranteeing optimal durability, friction coefficients, and load-bearing capacities for high-stress infrastructure.
Streamlined high-volume material distribution networks delivering critical building blocks directly to commercial and national infrastructure sites.
Project 2: Aggregate
Our Arizona operation showcases our ability to deliver large-scale aggregate production safely, efficiently, and responsibly. Located in a region known for rapid infrastructure growth, the site supplies essential materials for transportation, construction, and energy projects across the Southwest.
The operation integrates advanced processing systems, precise material handling, and progressive water management practices to ensure consistent, high-quality output. Arizona’s aggregate operations reflect our broader commitment to sustainable resource development — balancing performance with long-term environmental and community value.

Understanding RSC’s Work and Approach
RSC is built to take on large-scale mining and construction projects that demand both capacity and precision. Our core expertise lies in mass excavation, custom contract mining, and infrastructure development, where we move more than 100 million tons of material each year using advanced truck-and-shovel fleets. We work across multiple sectors, including frac sand, aggregates, base minerals, and precious metals, and have established ourselves as one of the leading contract miners in the United States.
Beyond mining, RSC delivers comprehensive construction capabilities, from building leach pads, drill pads, and utility trenches to constructing roads, pipelines, and other critical infrastructure. Our integrated approach allows us to manage entire project lifecycles—from site preparation and surveying to material handling, hauling, and final reclamation. With a premier fleet of modern equipment and more than 300 highly trained employees, we bring the scale, efficiency, and safety standards required for today’s most complex industrial and civil projects. Whether supporting mine development, public infrastructure, or large construction initiatives, Rango has the people, equipment, and experience to get the job done right.
At RSC, safety is more than a policy—it is a core value that guides every aspect of our operations. All employees maintain MSHA Part 46 and Part 48 certifications, ensuring they are trained and qualified to work safely in both surface and underground environments. We reinforce this foundation with ongoing safety education, daily site briefings, and frequent audits that keep teams alert and accountable. Our equipment is maintained to the highest standards and outfitted with advanced safety features, reducing risks on the job. Just as important, we foster a culture where every employee is empowered to speak up and stop work if they identify a hazard. This proactive approach ensures our crews, clients, and partners can count on safe, well-managed job sites every time.
RSC is deeply committed to environmental stewardship, understanding that responsible operations today protect the resources and communities of tomorrow. We integrate sustainable construction practices into every project, focusing on minimizing land disturbance, managing water responsibly, and reducing emissions through efficient fleet operations. In mining, we employ advanced techniques that maximize recovery while limiting environmental impact. Beyond production, we take an active role in reclamation, restoring mined land to beneficial use—whether that means returning it to natural habitat, preparing it for future development, or ensuring compliance with regulatory standards. From small-scale projects to complex Superfund initiatives, our dedication to sustainability reflects a long-term respect for the land and the people who depend on it.
RSC operates one of the premier equipment fleets in the industry, designed to handle the full scope of large-scale earthmoving and mining projects. Our lineup includes state-of-the-art Kenworth and Peterbilt tractors paired with a wide variety of trailers, giving us the versatility to transport equipment and materials of nearly any size. In the field, our heavy machinery ranges from high-capacity haul trucks and hydraulic shovels to loaders, dozers, and graders—each maintained to perform reliably under demanding conditions. We continuously invest in technology and equipment upgrades to increase efficiency, reduce downtime, and enhance safety on site. Beyond supporting our own projects, our logistics team provides third-party heavy haul services nationwide, ensuring equipment is relocated securely and on schedule. This combination of fleet strength and logistical expertise allows Rango to take on projects of any scale with confidence and precision.
