May 28, 2012· PB: The dogs can find all sorts of sulphide ore, whether it is zinc, copper or nickel, but we discovered they can also find oxide ore. We have just discovered a large deposit of arsenian pyrite, a gold ore, but every week we find they can sense a different type of metal in combination with sulphides.

Underlying physical and chemical processes of formation are common to many metallic and nonmetallic ore deposits. A good deal of data is lacking about the processes of ore formation, ranging from how metals are released from source rocks through transport to deposition and postdeposition alteration.

This does not necessarily mean that you directly see the ore deposit in front of your eyes. Many oreforming systems are accompanied by different kinds of alteration (for example potassic or argillic alteration) that are not too hard to see in the field. Once you see them, there is a possibility that an ore deposit is nearby.

Fortunately for humanity, geologic processes concentrate these minerals into accumulations called ore deposits. Simply put, an ore deposit is an economically significant occurrence of ore. The various kinds of ore deposits differ from each other in terms of which ore minerals they contain and which geologic conditions led to their formation.

Structures of Mineral Deposits

Structures of Mineral Deposits

Mineral deposits formed as a consequence of sedimentary processes. Structural deformation may alter the form and attitude of some of these deposits. Lenticular masses, veins, lodes and zones of disseminated mineralization result from metamorphic processes. Recognition of the environment and existence of potentially economic mineral deposits may be based upon a variety of geological criteria:

Newer mines have produced gold, lead, zinc, magnesium, and aluminum. Currently, Washington has several permitted metal mines, but only one of them is operational—the Buckhorn Mountain gold mine in Okanogan County, managed by Kinross Gold Corporation. The mines shown are by no means all of the metallic mines in Washington.
