bonanza grade gold mineralization meaning

Mining terms

Bonanza is used to describe a rich mass or ore found while mining. The word was derived from a Spanish term meaning fair weather and prosperity and became a common word in the mining industry. One of the centres at the beginning of the Klondike Gold Rush in the Yukon Territory was a 32km watercourse that branches off of Klondike River. Get price

One of his categories included deposits related to intrusive and eruptive igneous rocks that form veins at shallow depths that contain open cavity filling textures and that have been a primary source of bonanza grades of gold and silver--the epithermal deposits. Historically, most of the ores in Get price

How to Identify a Gold Bearing Area

Apr 25, 2017Research the geological properties of a particular gold-bearing area of interest. These properties include the rock formations, structure, fault lines and the primary mineral content of the area. Also, study the mineralization process of gold in general to determine which segment of a particular area may yield gold. (See Reference 1.) Get price

Recent Bonanza

Aug 05, 2019The World Gold Council defines a high-quality underground mine as having a gold ore density between 8 and 10 g/t (grams per ton), while a low-quality underground mine has a gold ore density of 1 to 4 g/t. Some view bonanza-grade as more than 34 grams of gold per tonne or more than one troy ounce of gold per ton. Get price

Consequently, targets of their drilling programs are areas of high-grade, bonanza mineralization that may exist within feeder zones underlying this extensive disseminated gold Get price

Continuity in Mineral Resource Estimation

May 04, 2016While geological continuity is important when constructing a mineral deposit model, in most cases it is the continuity of the grade of the mineralization that will determine the economic nature of a deposit. In fact, continuity and quality of mineralization and/or geology ultimately permit mineral deposits to be exploited. Get price

Base Metal

Base metal is a wide-ranging term that refers either to metals inferior in value to those of gold and silver, or alternatively, to metals that are more chemically active than gold, silver, and the platinum metals (AGI, 1957). Accordingly, a review of base-metal mineralogy would encompass much of the world's metal production and geology. Get price

Low Sulphidation Epithermal Gold Deposits

Although they are a product of the same igneous system, low sulfidation epithermals gold deposits are very different from high sulfidation. In low sulfidation the main control for Gold deposition, is fluid boiling – caused by a drop in the confining pressures the fluid approaches the surface. This below is an image of a simple low sulfidation vein system, with all its components preserved Get price
