Because marine deposits are distributed over large areas unevenly, mining companies utilize different methods to mine them. Some of these methods include shallowwater mining, deep sea operations involving high tech equipment and simple alluvial mining. Like open pit mining, the ore materials are usually transported offsite for further processing.

Gold and arsenic at Macraes gold mine. Pyrite grains at Macraes have had complex growth histories, as the deposit developed under a range of different structural and physical conditions, during uplift and cooling of the schist belt. Gold accompanied several stages of pyrite growth.
Geologic mapping provides many types of information essential both in exploration for new mineral deposits and during subsequent mining. Geologic mapping of outcrops is used to describe the primary lithology and morphology of rock bodies as well as age relationships between rock units.
Mineral exploration is a much more intensive, organized and professional form of mineral prospecting and, though it frequently uses the services of prospecting, the process of mineral exploration on the whole is much more involved. The foremost stage of mining starts with the process of finding and exploration of the mineral deposit.

gold introduced at two different stages; first with quartz and second with sulfides. gold irregularly distributed through vein material in visible particles uncombined with other elements. in some places the vein is richest adjacent to walls; in other places it is richest in center. sulphide rich portions of veins also contain gold.
Three stages have been identified in the Tianger gold deposits. Stage I occurs at a depth of 10 km under conditions of the amphibolite facies. Stage II, as constrained by metamorphic facies, is represented by zoisite amphibolites in mylonitized granite and the reaction of albite + 4 anorthite + 2H 2 O = pargasite + 2 zoisite + 2 quartz. Stage ...
The investment opportunity of a mineral project is evaluated and compared with the cost at different stages of exploration, development, and production with the expected revenue to be earned during the first 10–15 years of mine production. If the benefits are higher than the associated cost, then the opportunity is worth considering.
