A large aggregate producer was concerned that it was running short on available resources at its existing quarry. Unfavorable geologic conditions were appearing in the field, creating uncertainties about the amount of product that could be mined and used at its ready-mix and asphalt facilities. The company hired Barr to develop a geologic model for its existing quarry to estimate the amount of resource available at the quarry and develop a life-of-mine plan that was practical, economical, and safe.

To model the site’s geology, Barr logged previously drilled core samples. The model was then used to develop a set of mine plans that were discussed with the site manager and revised to fit the company’s needs and production goals.

The quarry’s expected life of mine was used to help support permitting efforts for opening a second quarry. Barr was asked to create a geologic model and mine plan for the second quarry, similar to that for the existing operation. The two plans were combined so that company operations could prepare for the transition.
