BIOGRAPHIES AND EXPERTISE
John R. Hellert, CPG, CEO, Senior Geologist. One of the primary focuses of Mr. Hellert’s professional career has been the exploration and development of construction aggregate production. For almost four decades he has been instrumental in the search, evaluation and development of sand, gravel and stone deposits across the globe. As a senior expert in the industry Mr. Hellert is sought out by clients to assist with such things as mergers and acquisitions, the assessment and evaluations of current and future mining costs. Such projects involve the sites geology, the cost of aggregate processing, it’s place in a market’s structure, the deposit’s relationships to transportation, environmental permitting costs. Along with the development of targeted deposits Mr. Hellert has conducted countless drilling campaigns to delineate and quantify reserves, he has developed material testing programs and beneficiation studies, planned mine layouts and sequencing and worked with the operator on equipment selection. Mr. Hellert was instrumental in the concept and development of the only underground aggregate mine in the Northeast. In addition to typical construction materials, Mr. Hellert has explored for cement rock, silica sand, gold, kaolin, black sands and feldspars.
