The valuation approach to a greenfield project will be substantially different from that applied to a well-drilled, extensively explored mineral property. Furthermore, a valuation exercise may produce different outcomes for the same gold project depending on which method is applied. In order to investigate the variability in valuation methods and

The theory of mine call factor (MCF) compares the sum of metal produced in recovery plus residue to the metal called for by the mines evaluation methods expressed as a percentage. The concept is well known in underground mining scenarios and therefore this article highlights some MCF issues from a ...

Mar 05, 2019· The reason is largely to do with location. Victoria's Dublin Gulch claim block is about 85 kilometers from the Mayo community, and accessible by road year-round. The White Gold property's Golden Saddle and Arc Zone deposits are 95 km south of Dawson City. Goldcorp's Coffee deposit lies 130 km from Dawson.

Computer Aided Ore Body Modelling and Mine Valuation 347 Fig. 1. Mine valuation work flow. 2. Database processes Database is the base of every further study. Health of projects entirely depends on health of samples. GPS records are very crucial to model topography. However, the most concrete data that can be taken from field is drill hole cores.

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 ...

Article written by Sci '14: Travis Dominski, Brett Kolankowski, Andrew Marck, Michal Pasternak, Steve Shamba. Production rate and mine life play a large role in determining the project economics.A higher production rate typically allows for lower operating costs, while the subsequent shorter mine life maximizes the Net Present Value of ore extraction.
