assay of gold ore from transvaal samples in case

Mineral Deposit Value - How to Calculate the .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 results.Make sure that this data is announced according to the guidelines of National Instrument 43-101 (i.e. approved by a ...

MANAGEMENT OF MINING, QUARRYING AND ORE-PROCESSING .management of mining, quarrying and ore-processing waste in the European Union. This project was completed mainly through the use of questionnaire sent to sub- contractors in almost each country of the EU. To assess this information and to extrapolate to the next twenty years, this approach has been reinforced using published estimators1 on the waste quantity from the knowledge of produced ...Using geochemical proxies to model nuggety gold .Gold distribution in vein-hosted hydrothermal ore deposits is commonly nuggety (i.e. occurs as very localised concentrations of gold). In these cases samples for gold assay from diamond drill core may be too small to model the underlying heterogeneity of gold distribution and result in poorly constrained ore body models and underestimated gold resources. Hence, it is common practice to use ...
