The method subdivides the estimated domain on the triangles which are constructed by joining the adjacent drill hole intersections (Fig. 16.1b). Average grade of the mineralisation constrained by a triangle is estimated as a length weighed average of the drill hole intersections forming the vertices of the studied triangle .

3.2.3: Overview of Reserve Estimation Methods. The polygon method is an old and established approach based on a simple geometric algorithm, in which we construct a polygon around each hole to determine an area of influence for that hole; and then the total volume directly beneath the polygon is assigned the same values as the drill hole from …
What Is Placer Gold?: Guide (Types of Gold Placers, Placer …
The Different Types of Placer Gold. Placer gold can be divided into several types depending on where it's found. For instance, gold that has just broken loose from the vein and rests in its vicinity is generally referred to as "residual placers", while gold that has made it into a stream is called "alluvial placer".
How To Find Natural Placer Gold: Ultimate Guide (Nuggets & Small Gold
Most of the natural gold found by prospectors today is the form of fine gold, such as gold dust and flakes of gold. Only 2% of gold found today is in the form of gold nuggets, which really demonstrates their rarity. As a prospector, most of the gold you are going to find will be very fine gold.

Ore Reserve Estimation Method
Ore-reserve estimates include the determination of (1) tonnages of ore and (2) average grade or value per ton. Since the grade or content of valuable metal establishes the difference between rock that may and may not be classed as ore, tonnage cannot be estimated without considering the question of grade. Consideration of grade in …

Reserve Estimation
The triangles are formed by joining three adjacent positive intersections defining a block. The plan area of each block is measured, and multiplied by the average thickness of mineralization, and average Sp. Gr. of ore to get tonnage. The average grade is computed by weighting averaging three corner values of the triangle. 2. Square and rectangle
