Abstract The Hishikari high-grade low-sulfidation epithermal gold deposit is located in the Hokusatsu district, about 30 km north of the Kagoshima International Airport, Kagoshima Prefecture (Fig. 1). In early 1981, a narrow (15 cm) but high-grade (290 g/t Au) vein was discovered 200 m below the surface by the Metal Mining Agency of ...

Gold Abundance in Igneous Rocks; bearing on Gold Mineralization
Economic Geology, 1973Review of quantitative data, restricted range in gold content (rarely more than 10 ppb, generally below 5 ppb), mafic rocks have more, so do early crystallizing minerals, no use in exploration, factors other than concentration determine mineralization ...

The Epidemiology of Tuberculosis in Gold Miners with Silicosis
American journal of respiratory and critical care medicine, 1994Abstract The elevated risk of tuberculosis in subjects with silicosis is widely accepted but has not been quantified in a population with a high prevalence of tuberculosis. In this study, a cohort of 1,153 older gold miners with and without silicosis who had not had tuberculosis have been followed for 7 yr by a routine mine ...

Gold mineralization at the Golden Blocks gold field
1978In the Golden Blocks area, vein-type gold and sparse sulphide mineralization occur in slightly metamorphosed, complexly deformed, Lower Ordovician sandstones and mudstones. Primary gold mineralization is associated with quartz veins in deformation zones occurring near the contacts of several carbonaceous mudstones.

Archean Gold Mineralization in Zimbabwe
1989Abstract Historically, and in recent years, most of Zimbabwe’s gold production has been derived from lode deposits, which range from pervasively silicified and sulfidized schistose zones and shear zone vein arrays to ribbon-textured and massive quartz veins.
