The results of carrying out this method through a complete orebody of a large tonnage seem to justify the labor involved thereinthe tonnage checks with the standard method to within 1014 per centthe standard method showed about 55000 metric tons less copper and the percentage by the standard method was about 00242 per cent less
Before you can calculate the potential mineral deposit value you first need to gather some specific data regarding the ore body and the individual drill results This required data can be found in the mining company’s press releases in which they announce their drill sure that this data is announced according to the guidelines of National Instrument 43101 ie approved by a
The tonnage in each block of ore is of course the volume in cubic feet divided by the cubicfeetperton factor or similar calculations for metric units When it comes to actual mining it often happens that the tonnage is greater and the grade of ore lower than estimated This often is due
