How much are your reserves worth?
{{image2-a:l-w:200}}Sometimes a better approach than having a thorough reserve estimate is to have the geologist conduct a best case or a worst case scenario. A best case scenario involves preparing an estimate of the potential reserves using the most optimistic values for deposit thickness, quality, extent, overburden and so forth.

Evaluation of the reserve of a granite deposit by fuzzy
This methodology, which was applied to one of the world''s most important deposits, represents an advance on the existing techniques used to estimate ornamental rock reserves, as it leads to a more realistic estimate that is based on considering the exploitation method, deposit anisotropy, and the fuzzy boundaries between commercial quality classes.

Cut-Off Grades For Mineral Resource Reporting: Going The
A cut-off grade (COG) is an industry-accepted standard expression used to determine what part of a mineral deposit to include in a mineral resource estimate (MRE). For MRE reporting, COGs tend to be rounded down to ensure that material of no economic significance is excluded from the resource. To calculate a COG, we can gauge the likely

Gravel Calculator – Square Footage Area
You can calculate the volume of gravel by multiplying area of gravel path by the desired depth: For e.g. 200 ft 2 * 1 ft = 200 ft 3; Purchase enough landscape rock to cover the area. If the area to be covered is 200 cubic feet, for example, each bag of rock covers 4 cubic feet ,so you will need 50 bags of landscape rock to fill the space.
