Natural Sand Proppant Production

To vertically integrate, Mammoth recently expanded its Natural Sand division through the acquisitions of Taylor Frac and Piranha Proppants (formerly Chieftain Sand). In total, we hold an estimated 75 million tons of sand reserves, all of which are the highest quality raw sand from our Northern White (Jordan and Wonewoc) deposits. Our reserves meet or exceed all API standards and confirm the premium nature of our sand. By year-end 2017 the company will have processing capacity of nearly 4 million tons per year, the majority of which will directly support our pressure pumping crews.   

All three of our facilities are located in Wisconsin with access to all major Class A railroads (see map below). Our mines are configured to produce various grades including the following:

  • 20/40
  • 30/50
  • 40/70
  • 100 Mesh
  • Custom Gradations - Due to the flexibility of our plants, we offer the ability to make any gradations that our customers desire


We own or have access to origin transloads with unit train capabilities on the Canadian National Railway Company (CN), Union Pacific (UP), Burlington Northern Santa Fe (BNSF) and the Canadian Pacific (CP) providing low cost transportation options into all of the major basins in the United States and Canada. We also own or control destination transloads in several basins with unit train capabilities. With more than 1,800 rail cars under lease, and when coupled with our last-mile capabilities, we are able to deliver sand directly from our mines to the well head eliminating the need for any third-party coordination providing savings for our customers.
