The ore body is generally tabular to trough-like in shape and is transversed by veinlets and stringers of an arsenic rich variety of tetrahedrite, tennantite. There is silver, lead and zinc associated with and combined with copper, arsenic, and vanadium rich minerals, rather than the more common association with galena and sphalerite..
Pering Mine is a lead (Galena) and zinc (Sphalerite) mine that is located in the southwestern portion of the North West Province close to the border with the Northern Cape Province. The nearest town, Reivilo is 20 km south west of the mine. Vryburg is 70 km north east of the mine.

Some galena grains are altered to lead sulfate and possibly lead oxide on exposed surfaces and along fractures (Fig. 2). Others are rimmed by fine-grained material which may contain a mixture of plumbojarosite and goethite. According to Jambor (1994), goethite and jarosite are two of …
Galena Group. Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide. It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms.

Lead is a naturally occurring metallic element usually associated with other ore minerals (primarily those of zinc, silver and copper) such as pyrite, sphalerite, quartz and barite.Trace amounts of other elements including gold are sometimes found with lead ore. The most common ore mineral of lead mined in the United States is galena with the chemical symbol PbS.
Galena is a lead sulfide mineral with a chemical composition of PbS. It is the world's primary ore of lead and is mined from a large number of deposits in many countries. It is found in igneous and metamorphic rocks in medium- to low-temperature hydrothermal veins.
Increases in turbidity may lead to higher unfiltered metal concentrations, and since waste disposal facilities invariably have more downgradient than upgradient monitoring wells, the probability of a turbid sample is more likely in a downgradient well than an upgradient well by chance alone.
Specialist consultant to the Nuclear Regulatory Commission on geohydrology, geochemistry, and solute transport aspects of regulation of deep geological disposal of nuclear waste. Founding Vice-President, MidWest Mining Company, Casper, 1986-1989. Technical director and manager of abandoned mined land projects performed in Wyoming.
The study, conducted by a Stanford University team, includes testing of biostimulation techniques and Bromide and TCE transport experiments. The geohydrology of this site consists of interlayered coarse and fine sediments in a shallow, confined aquifer, an alluvial aquifer, and a buried stream channel.
Geography Topography and drainage. Douglas County lies partly within the Dissected Till Plains and partly within the Osage Plains sections of the Central Lowlands physiographic province as defined by Fenneman (1931).
Galena is the standard metal of lead, and structures sparkling silver 3D squares with unnaturally flawless shapes. In spite of the fact that lead is ordinarily greatly adaptable, the sulphur substance of galena makes it phenomenally weak and receptive to compound treatment.
