Rock and Mineral Exploration

More than 200 Rock and Mineral Projects

CES has successfully completed more than 200 mineral and rock prospecting projects in Florida, across the United States, and in the Caribbean, Central America and the Yucatan of Mexico. These projects ranged from file and map reviews to field reconnaissance, sample collection and analysis, and full reserved calculations for limestone, dolomites, granite, Fuller’s earth, kaolin, silica sand and sandstone prospects, and deposits. Prospecting methods include test pits, auger drilling, sonic drilling, traditional coring, wire-line coring, phosphate barrel coring, split-spoon sampling, wash drilling, and air drilling. Rockwares and Surfer modeling are employed as necessary to estimate rock and mineral volumes. Here are just a few of the many projects we have completed.

MFM Industries Fuller’s Earth Prospecting
Central Florida

Identified potential sources of Fuller’s earth using geologic and topographic maps. Accessible sites were prospected using a variety of drilling methods. Including split-spoon sampling, direct push technology, and wire-line coring methods. Undisturbed samples were logged in the filed by a geologist for Fuller’s earth content. Selected samples were analyzed for clay mineralogy by x-ray diffraction (XRD) and for chemical impurities by traditional chemical methods. Samples were tested for bulk density and other physical properties. Isopach and structure contour maps were prepared using Surfer, and reserves were estimated for each site. Project let to the discovery of Fuller’s earth deposits that will greatly extend the life of the mining company.

Meridian Aggregates (now Martin Marietta) Ballast Prospecting
Southwest US

Inspected every igneous rock (granite, rhyolite, basalt, etc.) outcropping within 3 miles of the UP/SP Railroad between Los Angeles, California, and Van Horn, Texas. Outcrops were mapped in GIS using publicly available digital geological maps. Hand samples were collected from outcrops that appeared to display suitable ballast properties. Undisturbed rock samples were collected at selected locations using conventional coring equipment. Core samples were analyzed for Los Angeles (LA) abrasion, mill abrasion, bulk density, specific gravity, absorption, and silica content. Samples from superior deposits were also analyzed petro graphically in thin sections to determine rock type, major and minor mineralogy, ratio of crystalline to glassy matter, crystal size distribution, porosity, mode/degree of cementation, reaction rims, and degree of foliation. Project led to the discovery of a rhyolite deposit near Sierra Blanca, Texas that was leased and put into production and became a favorite ballast source of the UP/SP Railroad.

Schwab Ready Mix (now Preferred Materials) Limestone Prospecting
Lee County, Florida

Provided prospecting services to evaluate limestone aggregate mining potential of 2,100 acre citrus and farming tract. Project completed in 4 stages over 12 month period and consisted of 60 split-spoon mud-rotary borings through the overlying sand and shell and 39 wire-line core borings advanced to 90 feet. Undisturbed limestone samples from the core borings were crushed in the laboratory, graded to make FDOT No. 57 stone, and tested for a variety of properties including Los Angeles (LA) abrasion loss, specific gravity, and absorption. Yields were estimated using the crushing and screening data and reserves were calculated using computer models licensed by Rockwares, Inc. Final report included color three-dimensional block drawings and color cross-sections depicting the various lithological units penetrated by the borings.
