Mineral Ridge: A Late Cretaceous Orogenic Gold System in the Miocene Silver Peak-Lone Mountain Metamorphic Core Complex
Gold deposits in rocks of the Silver Peak metamorphic core complex in west-central Nevada are contained in highly deformed, sheeted milky quartz veins that cut Neoproterozoic metasedimentary rocks and Cretaceous peraluminous granite and migmatite. Gold production at Mineral Ridge since discovery in …

Genesis and structure of the San Albino orogenic gold deposit, NW Nicaragua with implications for Mesozoic tectonic and metallogenic processes
… the genesis and tectonic framework for orogenic gold deposits is critical for guiding exploration vectoring and understanding the geometry of ore zones within these systems. Thus, structural investigations are needed to establish a holistic deformational framework encompassing the …

Multi-stage orogenic gold mineralization of the Pine Lake greenstone belt: evidence from the Seabee Gold Operation, Trans-Hudson orogen, northern Saskatchewan
The Seabee Gold Operation, located within northern Saskatchewan, Canada, hosts the Seabee and Santoy deposits, as well as important exploration targets, including the Fisher property. These properties occupy the Pine Lake greenstone belt, hosted within the Glennie domain of the larger …

Structural and metamorphic evolution of the Ormsby Zone and relative timing of gold mineralization: a newly defined Archean orogenic gold prospect hosted on the Discovery Property, Yellowknife greenstone belt, Slave Province, Canada
… has produced approximately 14 million ounces of gold, 13 of which came from the well explored southern half of the belt. The northern half of the belt, where the Discovery Property (1 million ounce past producer) is located, is not as well explored, but geologically very similar to the gold …

Gold and Base Metal Mineralization, Hydrothermal Alteration and Vein Paragenesis in the Spring Valley Deposit, Pershing County, Nevada
Spring Valley is a gold-base metal deposit located on the eastern flank of the Humboldt Range in Pershing County, Nevada. Mineralization is primarily hosted within the Feldspar Porphyry, Agglomerate, Welded Tuff, Volcaniclastic Siltstone and Quartz-eye Rhyolite units of the Rochester Formation and …

CHARACTERIZING THE AURIFEROUS SYSTEM AT PORKY LAKE WITHIN THE PINE LAKE GREENSTONE BELT, NORTHERN SASKATCHEWAN, WITH A FOCUS ON PETROGRAPHY AND MINERAL CHEMISTRY
Gold mineralization occurs within the Pine Lake greenstone belt in several known and prospective deposits in northern Saskatchewan, Canada. The mineralization systematics at some of these locations within the Seabee Gold Operation, including the Porky Main and Porky West deposits, are poorly …

Major and trace element characteristics of biotite and chlorite as proxies for gold ore mineralization
… belt in eastern Finland is host to several orogenic gold occurrences. One of these deposits is the Pampalo gold deposit located in Hattu, Ilomantsi. Major and trace element characteristics of biotite and chlorite were analyzed from a representative collection of rock types of different …
