Geology and genesis of the Mount Skukum tertiary

The Tertiary Mt. Skukum gold - silver epithermal vein deposit occurs 65 km southwest of Whitehorse in the Yukon Territory. Veins are hosted by a sequence of nearly flat-lying Eocene Skukum Group andesitic volcanic rocks of the Mt. Skukum Volcanic Complex, part of the Sloko Volcanic Province which unconformably overlies these intrusive complexes as well as metamorphic rocks of the Yukon Group Get price

The Geology of Burma(Myanmar)

Deposits of silver, lead, zinc, and gold are concentrated in the northern Shan Plateau; tin and tungsten in the Tenasserim region, and barite around the town of Maymyo in the central basin. Copper mining at the town of Monywa began in the early 1980s and has been growing, despite intermittent setbacks caused by shortages of fuel and supplies as well as by economic sanctions imposed by foreign Get price

Technical Resource Document Copper Extraction And

1.4.1.2 Surface Mining Methods As indicated above, most copper is produced by surface mining methods. Surface mining involves the excavation of ore from the surface by removing overburden (nonmineralized soil and rock that cover an ore body) and waste rock (poorly mineralized or very low-grade soil and rock that are within the ore body or surrounding it) to expose higher-grade minerals.

A geochemical exploration program was applied to recognize the anomalous geochemical haloes at the Ravanj lead mine, Delijan, Iran. Sampling of unweathered rocks were undertaken across rock exposures on a 10 10 meter grid (n = 302) as well as the accessible parts of underground mine A (n = 42). First, the threshold values of all elements were determined using the cut-off values used in the Get price
