mineral prospecting: Prospecting is the physical search for minerals, fossils, precious metals or mineral specimens, and is also known as fossicking.

Prospecting is a small-scale form of mineral exploration which is an organized, large scale effort undertaken by mineral resource companies to find commercially viable ore deposits.

Prospecting is physical labor, involving traversing (traditionally on foot or on horseback), panning, sifting and outcrop investigation, looking for signs of mineralization. A prospector must also make claims, meaning they must erect posts with the appropriate placards on all four corners of a desired land they wish to prospect and register this claim before they may take samples.

 Car dognosis: Verify the fault. This is simply a matter of being sure that you know what the symptoms are before starting work. This is particularly important if you are investigating a fault for someone else, who may not have described it very accurately. Don’t overlook the obvious. For example, if the vehicle won’t start, is there fuel in the tank? (Don’t take anyone else’s word on this particular point, and don’t trust the fuel gauge either!) If an electrical fault is indicated, look for loose or broken wires before digging out the test gear. Cure the disease, not the symptom. Substituting a flat battery with a fully-charged one will get you off the hard shoulder, but if the underlying cause is not attended to, the new battery will go the same way. Similarly, changing oil-fouled spark plugs for a new set will get you moving again, but remember that the reason for the fouling (if it wasn’t simply an incorrect grade of plug) will have to be established and corrected. Don’t take anything for granted. Particularly, don’t forget that a “new” component may itself be defective (especially if it’s been rattling around in the boot for months), and don’t leave components out of a fault diagnosis sequence just because they are new or recently-fitted. When you do finally diagnose a difficult fault, you’ll probably realize that all the evidence was there from the start.
