About Us

Excellence and Experience in Aggregate Products

An innovative community partner, Allegheny Mineral is recognized as a superior producer of aggregate products, including limestone construction aggregate, industrial mineral filler, and aglime.



We are proud to be locally and nationally recognized for our mining techniques and reclamation projects. We care deeply about our people and the environment, not just the bottom line.


Rocks build America is more than just a tagline. Mined aggregate is needed to build homes, schools, churches, hospitals, and roads. Our goal has always been to supply the lifeblood of infrastructure projects while leaving as small an imprint as possible.


The cement and concrete industries have made bold goals of achieving net zero emissions. We intend to help them get there through collaborative research and development coupled with our products.


Each job in the aggregate industry creates an additional 5 jobs in the local economy. The positive effect of our facilities is both large and diverse.
