HI-CRUSH ONCORE PRONGHORN NEXSTAGE PROPDISPATCH Resources Investors About Careers OnCore Processing offers our clients a unique opportunity to stabilize the cost structure of their sand supply chain. By placing a small, built-for-purpose, and mobile mine on a client’s core acreage (or acreage very near to their core) a dramatic reduction in total mileage required to service their completions is realized. When combined with wet sand and our Pronghorn Last Mile business, Hi-Crush offers a platform of wet sand production and delivery that all but eliminates respirable silica for our collective employees at the wellsite and plant, eliminates unnecessary traffic on the roads of the communities we work in and reduces CO2 emissions all while providing significant savings to our clients.
