Mar 24, 2017 Ore Volume Calculation For flat-lying, bedded deposits of uniform thickness, volume computations involve merely scaling or measuring with a planimeter the areas of the different blocks of ore bounded by mine workings and the margins of the ore bodies and multiplying the area of each block by the average thickness of the ore in that block.
Aug 18, 2019 142545 Tonnes. 6.75. The global resource calculated for the Minetechpg copper deposit using triangular method is 142,545 tons extentsize ore at an average grade of 6.75 value Copper. In conclusion, the tonnage and grade determined using the two methods is
Jan 21, 2016 MINERAL ORE RESERVE Case 1. When all holes have positive values, let a, b and c, be the depth of ore in the three holes forming the prism to find the average depth of the ore influenced by any given hole, use the formula d 4a b c6. Then, as one proceeds from hole to hole, b and c should be substituted, thus 4b a c6 and 4c a b6,
Aug 18, 2019 Consider this regular drill pattern spaced 30m by 20m of High Grade at Minetechpg Copper Deposit.There are nine drill holes ranging from DDH 1 to DDH 9. Assuming the surface is flat and faultsdiscontinuities terminate the continuity of the deposit in which the drill holes define the boundary of the orebody, determine as accurately as possible the tonnage and grade of the deposit using Polygon ...
Recoverable coal resources are calculated by subtracting coal resources lost due to previous mining activities, exposure to weathering along outcrops, geological conditions, environmental, land use, or societal restrictions, and mining technology limitations from the total coal resources. ... and calculation of resources and reserves.

They include, but are not limited to, annual and quarterly company reports, press releases, information memoranda, technical papers, website postings and public presentations of Exploration Results, Mineral Resources and Ore Reserves estimates. The JORC Code was first published in 1989, with the most recent revision being published late in 2012.

Underground Mining Published March 1982 Algorithm for the approximate calculation of coal reserves and the distribution of reserves, based on thickness in an extraction field, in the planning of mining work. Yu. K. Pinigin amp V. I. Shtele Soviet Mining volume 18,
Dec 25, 2020 This is where the grade calculation from above is used. In the Kalana Mine feasibility study, the plant throughput rate is 1.5 million tonnes per annum Putting together the reserves estimate from above and the annual throughput rate, we model in our valuation 1.5Mtpa per year until we reach a cap of 19.5Mt. That is for 13 years 19.5 1.5.
