An investigation of an industrial minerals deposit by GSA Resources
includes an evaluation of:
The deposit its land status, location, and
The mining and processing methods and costs. The products and
coproducts their markets,
specifications, and prices.
The transportation shipping
mode, system, and costs.
The potential health hazards their
Consumers of industrial minerals often want to acquire deposits of the
minerals they use. GSA Resources can plan and operate both exploration programs and mining
operations. The professional staff capabilities include:
Planning and operating exploration programs including sampling and drilling operations.
Blocking out and calculating ore reserves.
Computing stripping ratios.
Establishing analytical methods and procedures. Developing sampling, grade and moisture
controls, and blending procedures.
Supervising mining and processing operations.
Determining the most economical system and mode of transportation.
The professional staff has detailed experience with the following
