Geological and structural controls on gold mineralization in …
Gold mineralization in the Tanami district is hosted within moderately northwest dipping turbiditic sedimentary and basaltic volcanic rocks of the Paleoproterozoic Mt. Charles Formation. The gold occurs within a complex sinistral wrench-fault array and associated veins and alteration haloes. The main mineralized faults have a northerly …
Limonite
The streak of pyrite is a blackish color with possibly a little green. The streak color of gold (which you are probably most interested in) is gold. Although finding gold with the limonite is unlikely, as I suspect what you are seeing is pyrite, finding gold with limonite is still possible.

Limonite
Gold bearing limonite gossans were productively mined in the Shasta County, California mining district. Similar deposits were mined near Rio Tinto in Spain and Mount Morgan in Australia. In the Dahlonega gold belt in Lumpkin County, Georgia gold was mined from limonite rich lateritic or saprolite soil.
Remobilization of gold from a chalcopyrite-pyrite
Native gold was formed during the latest, decreasing-temperature phase through remobilization of auriferous pyrite. Microprobe analysis confirmed that gold and copper are relatively enriched in the late pyrite. Identified surface-alteration products include goethite, limonite, gold, carbonates, and sulfates of iron and copper.
Characteristics Evaluation and High Effective Utilization of Limonite
This paper provided an overview of characteristics of limonite ores as well as their influence on sintering performance. Evaluation experiments focusing on basic characteristics, granulation characteristics, and high temperature sintering characteristics had been conducted by using two types of limonite ores, then the principles of high …

How to Separate Gold from Pyrite
Some authorities have contended that the metallic gold is disseminated mechanically through the mass of pyrites, but the action of potassium cyanide, in dissolving the whole of the gold out of comparatively coarsely crushed pyrites, seems to point to the correctness of the view that the interior of the crystal is not auriferous, the deposition ...
