The Golden Ridge gold deposit is located in southwestern New Brunswick, the Canadian Appalachians. Gold mineralization consistently associated with acicular arsenopyrite, and to a lesser degree pyrite, disseminated host rocks, sulphide veinlets, quartz-carbonate veins, breccia matrix. According petrographic-based textural differences, four types of pyrite two arsenopyrite are recognized assembl...

Potentially gold-bearing sediments in buried valleys in the Beauceville area have been sampled and studied using stratigraphic drilling techniques. These investigations show that river orientation transverse to dominant ice $ow directions, the relationships of preglacial and glacial sediments, oxidation at depth, brown colour in till, and distinctive geochemical data for Ni all provide importan...

Archean greenstone belts are renowned for their Au endowment. Gold can be associated with orogenic style of mineralization and diorite-hosted Au-Cu disseminated sulfides interpreted as a porphyry mineralization. The Regnault project, located in the Frotet–Evans belt (Superior craton), is structurally-controlled an unclear metallogenic model. aim this study to evaluate fertility granodiorite-dio...

This study focused on the interpretation of geophysical data collected from Sissedougou prospect which is located at southern end Korhogo-M’Benguebirimian trench. The surveys were carried out two grids with magnetometers and an induced polarisation unit composed a transmitter receiver. magnetic allowed one side mapping basic, intrusive volcanic formations, weakly rocks produced by meta-sediment...

Abstract The paper comprises new analytical data on the nature and occurrence of gold in solid pyrobitumen, closely associated with main gold-bearing sulfide arsenic ores Bakyrchik deposit (Kazakhstan), related to post-collisional magmatic-hydrothermal origin. Gold mineralization occurs mainly form an “invisible” type structures arsenian pyrite arsenopyrite, gold-organic compounds pyrobitumen c...

The results of the study, relationship regional faults with processes formation and mixing gold ore occurrences in Western Uzbekistan are presented. According to researchers, deposits region were formed under influence northwestern transverse northeastern faults. So that their research could serve as search signs predictive criteria, they have not been studied enough date. It is shown analysis ...

The mobility and microbially mediated solubilization of Au and As in regolith materials from two Au mines in Australia, i.e., the Peak Hill Gold Mine in semi-arid New South Wales and the Hit or Miss Gold Mine in tropical northern Queensland, was studied using a combination of geochemical and microbiological techniques. Gold is highly mobile in both environments, the mobility of Au increases wit...
