    And where better to look than in northwestern Ontario, where two such mines are operating. Placer Dome’s Campbell mine has been turning out well over 10 million ounces from ore grading about ounces per ton (oz/t) Au, since Goldcorp’s Red Lake mine started up in and has about 4 million ounces to its credit. The salinity and temperature of ore-forming fluids have wide ranges. Salinities of some ore-forming fluids are lower than sea water, whereas those in fluids forming porphyry deposits can reach 80 wt.% NaCl (Heinrich, ).The salinity and temperature of most hydrothermal fluid decrease during the late-stages of ore formation, suggesting either the attenuation of heat and fluid source or the.

    Comprised of 69 full and partial cells covering 1, ha within the Red Lake Greenstone Belt, the property is located 15 km north of the town of Red Lake and is contiguous with Rubicon Minerals’ Slate Bay gold property (click on maps below to enlarge). Today the Red Lake District is composed of five communities, all built around former or currently operating gold mines. So far, over 21 million ounces of gold have been extracted from deep underneath the many lakes, rocks, and trees that form the landscape of the area. Prospectors are still discovering major high-grade ore deposits, and gold.

    Much of the Gold mined is from large mining operations where the Gold is smeltered for commercial use, and although many commercial gold mines exist, mineral specimens and crystals are hard to come across. China and South Africa have been the worlds two largest Gold producers, but collectors will rarely if ever see a Gold specimen from these countries due to the restrictive nature of the. Distribution of gold resources in orogenic gold deposits, and related placer gold endowment, over geologic time. A. Precambrian gold resources are mainly the product of ore-forming events clustered between and and and Ga. B. Phanerozoic gold resources indicate relatively continuous gold-forming events during orogenic events.

Recent geophysical work by Red Lake Gold Inc. has defined a western extension of the LP Fault structure onto the Whirlwind Jack Gold Project for at least 12km, with the project being contiguous to the Dixie Project being advanced by neighbouring Great Bear Resources Ltd.

Auriferous sedimentary rocks at the Dickenson Mine, Red Lake, are characterized by large enrichments of rare elements (Au, Ag, Pd, As, Sb, B) and metals conventionally considered to be relatively immobile (Ni, W), with negligible concentrations of the abundant and mobile base metals.

The Kirkland Lake-Larder Lake gold belt includes the giant Kirkland Lake and world-class Kerr-Addison-Chesterville gold deposits, along with several smaller deposits and occurrences. It corresponds to an east-trending band of Timiskaming clastic and volcanic rocks that unconformably overlie older volcanic assemblages in the southern Abitibi.

The stratified rocks straddling the Larder Lake-Cadillac Break historically have been subdivided into two volcanic and two sedimentary groups (Wilson, ).The older volcanic unit, composed mainly of ultramafic to mafic rocks with rare felsic units, is termed the Malartic Group in the eastern part of the area, while its equivalent in the western part is referred to as the Larder Lake Group.

Veins are common in greenstone gold deposits, in many cases forming a major portion of the ore, but overprinting it in others (e.g., Tourigny et al., ; Robert, ).Veins, like unconformities and igneous intrusions, are also useful in separating deformation predating their formation from subsequent increments of strain.

The Red Lake Gold District is host to some of the richest gold deposits in the world and has produced 30 million ounces of gold from high grade zones, including 18 million.Mesothermal gold deposits form half way up through the rise of the melt from the deep crust to the surface usually at a depth of less than 10 km but greater than 1 km.

temperatures at these depths are generally somewhere between degrees and degrees Celsius. The term mesothermal veins is really a sack term, referring simply to the depth formation. It pays little attention to the origin.GOLD IN MINERALS AND THE COMPOSITION OF NATIVE GOLD By ROBERT S.
