Limonite often replaces pyrite crystals and other materials.
Limonite (/ ˈ l aɪ m ə n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)· n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and ...
This page is dedicated to the gold that's 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 2.65 times heavier than water, whereas pure gold is 19.3 times heavier ...

Gold Prospectors like to generalize gold deposits into two groups - lode gold (gold which is found in place in outcrop) and placer gold (detrital gold eroded from a nearby lode and deposited in a stream). Both deposits are important, but for the gold prospector, placer gold deposits are most important because many can be worked with smaller resources and less cost that most lode gold deposits.
A similar case was noticed by Mactear in South America, where a limonite ore which only yielded from 35 to 40 per cent, of its gold when treated in Huntington pans, was made to yield between 85 and 90 per cent, by merely subjecting it to a dehydrating calcination before amalgamating it. ... Richard Daintree and Latta found specimens of cubical ...
Many chemically formed ore shoots yield good ore deposits. During vein formation, hot silica (quartz-rich), hydrothermal acidic fluids react with rocks with favorable chemistry; particularly rocks with calcium carbonate (limestone, dolomite). Thus, following a vein that cuts through limestone could lead prospectors to find skarns, replacement deposits, etc for gold and other valuable minerals.
