The worlds highest grade gold mines
In 2012, two barges carrying highgrade gold ore presumably from Avlayakan mine, capsized and sank in the Okhotsk Sea. With remarkable g/t ore grade, this openpit mine sits first in our ranking.

#0183;#32;3. The geochemical behavior of gold in hydrothermal systems. The occurrence of gold mainly depends on temperature, pressure, pH values, Cl concentration, and fugacity of H 2 S in a hydrothermal system. Gold mostly occurs as AuCl 2 in a system with temperature higher than 400 #176;C (Gammons and WilliamsJones, 1997), and with decreasing temperature being the primary mechanism causing gold
This page is dedicated to the gold thats still attached to quartz, or a host rock. This type of gold is highly desired in the mineral collecting community. Gold/Quartz specimens are in a completely different league of their own. Remember the specific gravity of quartz is times heavier than water, whereas pure gold is times heavier
High Grade Gold Ore From A Quartz Vein Near Alma Colorado. These superrich zones are often the sources of specimengradehighgrade that can be prepared to produce the beautiful gold specimens for which the red lake mine is becoming famoushen geologists encounter the superhighgrade areas, they collect any likely looking goldbearing ore and place it in locked, metal boxes.
Also consider that gold concentrations in ore is never consistent, often occurring in pockets rather than consistently throughout. So a mine that produces some highgrade ore will also process tons of ore with almost no value. To the naked eye, these ores may look exactly the same.

Ore bodies are formed by a variety of geological processes.
Gold mineralization within the Cripple Creek district occurs in two principal styles. Mineralization occurs as (1) broad zones of lowgrade, goldpyrite mineralization which is microfracturecontrolled and disseminated and (2) as fracture zones containing highgrade, goldsilver tellurides.
A highgrade deposit could have gold values ranging from 10 to more than 150 grams per tonne, whereas a lowgrade deposit grades in the range of 1 to 5 grams. Lowgrade deposits may have up to, and possibly more than, 200 million tonnes of rock, whereas a highgrade deposit is frequently smaller.
This gold ore is typical of a great series of deposits extending north and south from near Carlin, Nevada have silver and tellurium mineral. This is very high grade gold ore from the Cripple Creek district in Colorado. Many This ore shows considerable bright and visible metallic gold disbursed through the quartz vein gold ore.
