The valuation approach to a greenfield project will be substantially different from that applied to a welldrilled, 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
Methods that can be used for reserve estimation and placer valuation are (1) block method (2) triangle method (3) polygonal method (4) crosssection method (5) method of diamonds SAMPLING. The sampling methods outlined previously vary from simple grab samples on existing exposures to sophisticated drilling methods. The disposition and density ...

The process of exploring for diamonds is actually exploration for the host rock that carried the diamonds to the surface – kimberlite. Kimberlite is a volcanic rock that occurs in diatremes, or narrow volcanic "pipes". It may also occur in vertically oriented narrow sheets, or dikes.
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 yearround. 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.
Prospecting and exploration that is a search for precious metals deposits is not a simple process because big deposits were discovered a long time ago. There are several places with important content of precious metals waiting for skill prospectors. The large mining companies of the world are focused in big deposits and the small deposits are attractive for small miners and perhaps their ...

A method virtually the same as the foregoing has been employed at the WrightHargreaves mine, Kirkland Lake, Ontario. In estimating the grade of a given block of ore or averaging the assays along a section of a drift, all the assays, including the erratic highs at their full value, are first averaged by the dollarfoot method.

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 ...
