(mining engineering)
A method of estimating ore reserves in which it is assumed that each drill hole has an area of influence extending halfway to the neighboring drill holes.

A Table of the JORC Code Inferred Resource is outlined below; TABLE 1 CORELLA BORE / PHM SOUTH INFERRED RESOURCE (KORELLA DEPOSIT) (Computer Generated Polygonal Method Based on Simple Flat to Low Dipping Tabular Body)
Reserves were calculated using the standard polygonal method and geostatistical methods.
The resource was manually calculated using a longitudinal block section method which was duplicated and verified by a polygonal method using "BORSURV" software.
The mineral resources are in addition to the reserves and were estimated by the polygonal method using drill hole data that met the minimum geologic width and cutoff grade as follows:
The resource was calculated using a Plan Polygonal method with a 90-metre radius from each drill hole and a 2-metre maximum waste gap.
Resources were calculated with the Gemcom software for zones B2, BN and P and with the polygonal method on a longitudinal section for the other zones.
5 metres to 50 metres, most commonly 25 metres, and using the polygonal method on vertical longitudinal sections.
E[acute accent]- Mineral resources and reserves were estimated using the polygonal method on vertical longitudinal sections
A conventional polygonal method was used to calculate the volume of mineralized blocks within geologically defined limits on longitudinal section.
The resource calculation was done using a conventional longitudinal polygonal method after performing geological interpretations on cross-sections and longitudinal sections constructed in GEMCOM.
All inferred resources were determined using vertical longitudinal sections, the polygonal method of volume calculation and a specific gravity factor of 2.
These include the mineral resources, as estimated using the polygonal method in the plane of the 2S, 3S, and Intermediate vein, or vein zone structures, within a Discovery Zone that is approximately 150 metres long, 30 metres wide and 75 metres deep.
