We’re listening. . .at coffee in London or at an industry meeting in Vienna. As a global mining expert, we’re always gathering valuable information and gaining insights to help our clients.

A world-renowned integrated technology solutions provider with state-of-the-art laboratories, RESPEC’s distinguished team of engineers, scientists, and IT experts works with international clientele to perform reserve analyses and mine design.  Using database validation, geostatistical analysis, block modeling, section plotting, and interactive geological modeling, our culturally attuned professionals are adept at reserve estimation and appraisal.

Founded in 1969, RESPEC has a long history of developing block models to help clients accurately estimate the tonnage and grade of their geological deposits.  We conduct multiple reserve evaluations for surface and underground mining operations. Whether our team is block modeling the overburden geochemistry for identifying toxic strata in a surface coal mine or the limestone chemistry needed to optimize cement plant feed for surface and underground limestone mines, RESPEC’s team facilitates client decision making with clear data that is easy to understand. RESPEC is also experienced in large-scale, coal-reserve modeling assignments, including a 200,000-acre resource review in Tennessee and a 32,000-acre landholding evaluation in West Virginia.
