23-12-2017· Prospecting an near by ore body as well, which has semi and massive sulfides striking through disseminated pyrite and chalcopyrite in the host rock these samples assayed as high as 8g/ton Gold, 33g/ton Silver and up to 1% copper and molybdenum. The ore body is thirty meters away from a quartz vein in the old quarry.
Gold and silver are obtained from a variety of ores, in some of which the gold predominates, in others silver is the primary value, while in still a third class these two metals may be mixed with the base metals, such as lead, copper, zinc, and iron.
A GOLD-PLATINUM-PALLADIUM LODE IN SOUTHERN NEVADA. By ADOLPH KNOPF. INTRODUCTION. The discovery of platinum-bearing gold ore at the Boss mine, in southern Nevada, was brought to the attention of the Geological Survey by Mr. F. A. Hale, jr., in September, 1914. Some samples of the ore were submitted at the same time.
Platinum is the rarest and most expensive of the popular precious metals. It is much rarer then Gold. Due to its rarity and value, it is not readily available to mineral collectors and is seldom represented in in all but the highest-end mineral collections.

Gold. Gold may be used to make watch cases, bezels, bracelets and the most precious parts of the movement. However, gold in its pure state is too malleable, so silver, copper and palladium are alloyed to it to give it the necessary hardness and mechanical resistance.
The modern use of the term white gold usually concerns gold alloyed with any one or a combination of nickel, silver, platinum and palladium to produce a silver-coloured gold. Composition. Electrum consists primarily of gold and silver but is sometimes found with traces of platinum, copper, and other metals.

Gold. Gold may be used to make watch cases, bezels, bracelets and the most precious parts of the movement. However, gold in its pure state is too malleable, so silver, copper and palladium are alloyed to it to give it the necessary hardness and mechanical resistance.
The gold group consists of gold, copper, lead, aluminium, mercury, and silver. The platinum group consists of platinum, iridium, osmium, palladium, rhodium, and ruthenium. Amongst the alloys found in native state have been brass, bronze, pewter, German silver, osmiridium, electrum, white gold, and silver-mercury and gold-mercury amalgam.
Our assay tests reveal this type to gold ore to contain: copper, iron, gold, silver, platinum and rhodium. Associated minerals include Kostovite and Goldfieldite. All the paperwork displayed in the photo, which includes a copy of the assay test from the area of discovery and other valuable information about this piece are also included.
How to Find Gold in Quartz Gold is easy to spot in white quartz. Use your geology hammer and sledge to break open quartz and potential gold-bearing rocks. Place an iron or steel anvil in a large flat pan to prevent loss of rock powder and contained gold.
Gold and silver are obtained from a variety of ores. Most people think of nuggets and such, but the truth is that very little comes from nuggets nearly all newly mined gold comes from ores mined from the natural hard rocks that contain gold in tiny, even microscopic particles.

Bright white quartz with streaks of gray are a good indicator of the presence of silver ore. Inspect each rock carefully since some silver deposits will be barely visible. Some silver runs through its host rock as "spider veins" that streak the interior of the rock and terminate just at the surface.
Veins of gold, such as this one trapped in quartz and granite, may deposit when the high-pressure water in which they were dissolved suddenly vaporises during an earthquake. Scientists have long known that veins of gold are formed by mineral deposition from hot fluids flowing through cracks deep in
Gold in Wyoming. Gold, the intrinsically valuable "royal metal," derives its value from the combination of its rarity and beauty along with its softness (2.5 to 3 on the mohs hardness scale), malleability, ductility, ease of alloying with other metals such as copper and silver, and
Veins of gold, such as this one trapped in quartz and granite, may deposit when the high-pressure water in which they were dissolved suddenly vaporises during an earthquake. Scientists have long known that veins of gold are formed by mineral deposition from hot fluids flowing through cracks deep in

GOLD IN MINERALS AND THE COMPOSITION OF NATIVE GOLD By ROBERT S. JONES and MICHAEL FLEISCHER ABSTRACT Gold occurs in nature mainly as the metal and as various alloys. It forms complete series of solid solu tions with silver, copper, nickel, palladium, and platinum. In association with the platinum metals, gold
Quartz can be transparent, translucent or opaque. If vein quartz contains gold, we get excited. If barren, such as “bull quartz” (a prospectors term for milky white, massive quartz) we may decorate our rock gardens with the rock. Quartz is the most common mineral on the earth's surface.
