The Superior Craton is a stable crustal block covering Quebec, Ontario, and southeast Manitoba in Canada, and northern Minnesota in the United is the biggest craton among those formed during the Archean period. A craton is a large part of the Earth's crust that has been stable and subjected to very little geological changes over a long time. The size of Superior Craton is about. Most of the gold found in Ontario is found in the so-called Greenstone Belts the largest of which is the Abitibi reaching all the way from Wawa on Lake Superior into Quebec past Val D’or. From this one Greenstone Belt there are more then ,, ounces of gold that have been mined since its discovery in Author: Geotek. Rich Hemlo gold field still churning it out There are just three gold-producing mines in the Schreiber-Hemlo District, but what is lacking in quantity is more than made up for in quality. In million ounces of gold were produced by the David Bell, Golden Giant and Williams mines, all of the Hemlo Gold .

The western portion of B Zone Mineral Reserves includes two or three mineralized zones within the typical host lithology. Internal waste pillars of at least 10 m horizontal thickness separate these zones.
This mineralization represents the fringe of the Hemlo Lithology and as such, continuity of grade and thickness becomes increasingly erratic. Access Description: The Armand Lake gold occurrence is located approximately 33 km south-southeast of Manitouwadge, m north-northeast of the east end of Musher Lake, and m west of the west end of Armand Lake.
The Hemlo gold deposit is located approximately 16 km to the southwest. The area surrounding the occurrence is underlain primarily by a northeasterly-trending sequence of mafic to felsic metavolcanic and lesser metasedimentary rocks which comprise a portion of the the north limb of the Schreiber-Hemlo greenstone belt (MilneMap ; Siragusa and ChiversMap P).
Such remobilization and upgrading of gold are a wellknown phenomenon and have been studied in several gold mineralized deposit types, including gold-rich VHMS (e.g., Wagner et. The Alpala porphyry copper-gold deposit is part of a cluster of mineralised systems in the Cascabel district, ~ km north of Quito, 20 km south of the Colombian border in far northern Ecuador, and ~65 km to the NE of the Llurimagua/Junín deposit (#Location: 0° 45' 13"N, 78°: 19' 54"W).

Gold deposits encompass a wide variety of geological environments. Depending on the deposit type (i.e. epithermal, mesothermal, porphyry-style, disseminated, BIF-hosted, IOCG, skarns, lode, etc.), they are associated with a wide-range of alteration assemblages.
The Carrapateena iron oxide copper-gold deposit, which is located within the Olympic IOCG Province on the eastern rim of the preserved Gawler craton in northern South Australia, is ~ km SSE of Olympic Dam and ~ km north of Port Augusta in South Australia, immediately to the SW of the Carrapateena embayment on the central-western shore of Lake Torrens.
The concentration of gold in the Earth's crust and mantle is extremely low and highly variable, resulting in ore variability in many gold and copper–gold deposits.
More importantly, gold in an ore may occur in two or three forms (i.e., microscopic gold, submicroscopic gold, and surface gold), making gold ore processing extremely challenging. A trail of mineralized boulders, including one that provided a grab sample at g/t Au, was identified inand followed up-ice to the source area, leading to the discovery of the Roberto.
