Silver Queen mint in central British Columbia, is located approximately 35 kilometres south of Houston and 3 kilometres east of 0wt.n Lake (Figure 2-7-1). Although currently inactive, it was worked briefly in the early 1970s for gold. silver, copper, zinc, lead and cadmium. The deposit is hosted by Cretaceous rocks of the informal Tip Top Hill group (78.322.67 Ma, K-Ar whole rock), with the age...

A variety of regional geoscience datasets from Nova Scotia have been co-registered and analyzed using a geographic information system (GIS). The datasets include bedrock and surficial geological maps, airborne geophysical survey data, geochemistry of lake-sediment samples, and mineral occurrence data. A number of line features, including structural lineaments, fold axes and formation contacts, ...

A bidimensional empirical mode decomposition (BEMD) program on a MATLAB platform was effectively used to handle gravity signals for the Tongshi gold field. This yielded a two-dimensional intrinsic mode function (IMF3) image that meticulously depicts the spatial distribution relationship between various gold deposits and the different geological units of the gold field. By combining the IMF3 ima...

This article investigates the effect of material size on efficiency flotation concentration gold-copperarsenic ores Taror deposit (Republic Tajikistan) and studies dependence gold recovery duration process with purpose developing an alternative technological scheme for processing this ore type. According to X-ray phase analysis, samples consist rock-forming minerals by 92%. Ore mineralization i...

25 26 The Tropicana gold deposit is located adjacent to the margin of the Yilgarn craton in 27 the Albany–Fraser orogen, Western Australia. The deposit is hosted in granulite facies 28 quartzo-feldspathic gneisses of the Archean Tropicana Gneiss. Ore bodies comprise 29 biotite-pyrite alteration concentrated in shear zones that formed during NE-SW 30 shortening in the late Archean, and clearly p...
