Prospecting in the context of "Colorado"

Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains a valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.

Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation or restoration of the land after the mine is closed. Mining materials are often obtained from ore bodies, lodes, veins, seams, reefs, or placer deposits. The exploitation of these deposits for raw materials is dependent on investment, labor, energy, refining, and transportation cost.

A hammer is a tool, most often a hand tool, consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nails into wood, to shape metal (as with a forge), or to crush rock. Hammers are used for a wide range of driving, shaping, breaking and non-destructive striking applications. Traditional disciplines include carpentry, blacksmithing, warfare, and percussive musicianship (as with a gong).

Hammering is use of a hammer in its strike capacity, as opposed to prying with a secondary claw or grappling with a secondary hook. Carpentry and blacksmithing hammers are generally wielded from a stationary stance against a stationary target as gripped and propelled with one arm, in a lengthy downward planar arc—downward to add kinetic energy to the impact—pivoting mainly around the shoulder and elbow, with a small but brisk wrist rotation shortly before impact; for extreme impact, concurrent motions of the torso and knee can lower the shoulder joint during the swing to further increase the length of the swing arc (but this is tiring). War hammers are often wielded in non-vertical planes of motion, with a far greater share of energy input provided from the legs and hips, which can also include a lunging motion, especially against moving targets. Small mallets can be swung from the wrists in a smaller motion permitting a much higher cadence of repeated strikes. Use of hammers and heavy mallets for demolition must adapt the hammer stroke to the location and orientation of the target, which can necessitate a clubbing or golfing motion with a two-handed grip.

In Australia, New Zealand and Cornwall, fossicking is prospecting, especially when carried out as a recreational activity. This can be for gold, precious stones, fossils, etc. by sifting through a prospective area. In Australian English and New Zealand English, the term has an extended use meaning to "rummage". Though the term has been argued to come from Cornish, it likely originates from the Latin fossa, meaning “ditch”, “trench”.

In Australia, "fossicking" is protected by a number of laws, which vary from state to state. In Queensland, fossickers must obtain a licence, but no licence is required in New South Wales. In South Australia, fossicking is defined as "the gathering of minerals as (a) a recreation; and (b) without any intention to sell the minerals or to utilise them for a commercial purpose", and these activities are considered as not being affected by the Mining Act.

Boring is drilling a hole, tunnel, or well in the Earth. It is used for various applications in geology, agriculture, hydrology, civil engineering, and mineral exploration. Today, most Earth drilling serves one of the following purposes:

• return samples of the soil and/or rock through which the drill passes
• access rocks from which material can be extracted
• access rocks which can then be measured
• provide access to rock for purposes of providing engineering support

Unlike drilling in other materials where the aim is to create a hole for some purpose, often the case of drilling or coring is to get an understanding of the ground/lithology. This may be done for prospecting to identify and quantify an ore body for mining, or to determining the type of foundations needed for a building or raised structure, or for underground structures, including tunnels and deep basements where an understanding of the ground is vital to determining how to excavate and the support philosophy. Drilling is also used in vertical and inclined shaft construction.

The Klondike Gold Rush was a migration by an estimated 100,000 prospectors to the Klondike region of Yukon in northwestern Canada, between 1896 and 1899. Gold was discovered there by local miners on August 16, 1896; when news reached Seattle and San Francisco the following year, it triggered a stampede of prospectors. Some became wealthy, but the majority went in vain. It has been immortalized in films, literature, and photographs.

To reach the gold fields, most prospectors took the route through the ports of Dyea and Skagway in southeast Alaska. Here, the "Klondikers" could follow either the Chilkoot or White Pass trail to the Yukon River and sail down to the Klondike. The Canadian authorities required each person to bring a year's supply of food in order to prevent starvation. In all, the Klondikers' equipment weighed close to a ton, which most carried themselves in stages. Performing this task and contending with the mountainous terrain and cold climate meant that most of those who persisted did not arrive until the summer of 1898. Once there, they found few opportunities, and many left disappointed.
