The Alaska Juneau lode gold deposit is hosted by a series of polydeformed Permian to Late Triassic volcanic, pelitic, volcaniclastic, and mafic intrusive rocks. Giga-fren Mesothermal lode gold deposits are prominent in the Beardmore–Geraldton camp.

Gold A particularly valuable precious metal. Gold is an element with the atomic number 79. It is used for jewelry, electronics and for other purposes. Historically, gold was used in many cultures as the basis for currency, but this is no longer the case. Investments in gold are often used as a hedge against inflation because it tends to maintain its ...

The process of lode, or hard rock, mining, on the other hand, is the process by which gold is extracted directly from the lode beneath the ground. Lode mining requires the labour of many miners working together to extract the gold from tunnels or massive open pits in the ground.

The MOTHER-LODE is a principal vein, or zone of veins, of gold or silver ore. The term is also used colloquially to refer to the origin of something valuable or in …

Gold is gold, so there isn't necessarily a better type of gold. However, mining for lode gold has many more challenges that mining for placer gold. Placer gold mining is much easier. The gold is already separated from the rock, and gravity has concentrated the gold into creeks and rivers where it is more easily accessible.

The AMC # for the 40 acre placer Free Gold is 405331, Free Gold-A lode is AMC # 405535 and Free Gold-B is AMC # 405536. These claims are part of the old San Marcos Mine workings and the area is saturated with old mine workings, trenches, pits and shafts. A recent rock chip sample taken from a mine dump returned over 1.5 ounces per ton.

Gold mining operations may be carried out by either placer mining or lode mining. Lode mining is also called hard rock mining. Originally, all gold is deposited in a lode or vein filled with mineral in the rock, such as the gold-rich veins discovered in Cow Mountain. When these lodes are disintegrated by natural erosion, such as water flowing over the rock, placer gold is the result - the ...

Intrusive Gold. Intrusive gold is formed in a way vary similar to lode gold. Magma penetrates into solid rock walls carrying the gold within it. When the magma cools it leaves new layers of rock and minerals, including gold, inside of the existing rock. Placer Gold. Placer gold is formed from already existing lode and intrusive gold deposits.

Gold is mainly found in two types of deposits: lode (hard rock veins) and placer (surface). Locating the richest gold bearing areas primarily involves research, planning, dedication and funds. In other words, those who study geological surveys, land formations, rock structures and gold prospecting history prior to prospecting may have a better ...

What is lode gold? Lode is deposit of valuable ore with some definite boundaries, separated from surrounding rock.. Lode gold is the rock found in lodes, usually the original gold, not separated from rocks. This type of gold is majority of gold that is produced by gold mining companies world wide.. Lode gold is not in the state to be bought, it is gold that is located in rocks.

Gold is relatively scarce in the earth, but it occurs in many different kinds of rocks and in many different geological environments. Though scarce, gold is concentrated by geologic processes to form commercial deposits of two principal types: lode (primary) deposits and placer (secondary) deposits.

California Mother Lode. In the United States, Mother Lode is most famously the name given to a long alignment of hard-rock gold deposits stretching northwest-southeast in the Sierra Nevada of California.It was discovered in the early 1850s, during the California gold rush.The California Mother Lode is a zone from 1.5 to 6 kilometres (0.93 to 3.73 mi) wide and 190 kilometres (120 mi) long ...

Lode Gold. Lode gold occurs within the solid rock in which it was deposited. Areas likely to contain valuable lode deposits of gold have been explored so thoroughly that the inexperienced prospector without ample capital has little chance of discovering a new lode worth developing.

Mar 07, 2017· Placer Mining Vs. Lode Mining. There are two kinds of places where a prospector can find gold: the original veins of gold where it was formed in the rock or in deposits where natural actions such as water has eroded pieces of gold away from the original host rock.

What is a Lode Claim? They also include other rock in- place bearing valuable minerals and may be broad zones of mineralized rock. Examples include quartz or other veins bearing gold or other metallic minerals and large volume, but low-grade disseminated gold deposits.

Lode definition, a veinlike deposit, usually metalliferous. See more.

The Mother Lode gold belt carries the most productive and best-known mining districts in California's gold country. Although the entire foothill region of the Sierra Nevada is sometimes loosely termed the "Mother Lode Country," technically the Mother Lode is a 120-mile-long system of linked or en echelon gold-quartz veins and mineralized schist and greenstone that extends from the town of ...

Placer gold and lode gold both come from the same place and are made of the same stuff. Gold is not actually formed on earth it was formed millions of years ago in distant stars. In large stars, much larger than our sun elements are combined together in their cores through the process of nuclear fusion.

'Copper crystals from the conglomerate lode are rare and commonly exhibit the tetrahexahedral form.'

The state's biggest gold rush began with the first major discovery of lode gold at Idaho Springs in 1859 and later a huge strike at Central City Thousands of "fiftyniners" poured in, but the rush faded quickly; by 1861, surface gold was played out.

Sep 12, 2018· Placer gold deposits are usually not far off from where lode gold deposits are.

Prospecting for lode deposits begins with a search for mineralized outcrops, the key to the existence of which may often be found in mineralized float (pieces of rock from the lode that have been loosened by weathering and washed downhill). Geologists now generally agree that most valuable mineral deposits have a magmatic origin and, therefore, that the most promising areas to prospect are in ...
