Veins generally. In mining: veins, lodes or ore-bodies. They are normally precipitates of metallic compounds.
In Formation was created in 1982.
HudBay Minerals was created in 1996.
Accumulating deposits of sand from wind or water deposition are initially created. The weight from the deposits above cause compaction of the lower deposits. Compaction forces out air and water that exists between the sand grains. Minerals form from the remaining concentrated solutions in a process called precipitation. These minerals act as a cement which binds the particles of sand together, creating sandstone.

Metals, minerals, precious stones were not "obtained" by nature. They were formed along the time, on a very slow process, or many of them have been created together with the initial formation of the Earth, and other planets.
The Philippines has an abundance of large mineral deposits due to its complex geology, which includes various tectonic activities and volcanic eruptions over millions of years. This geological history has created mineral-rich zones that are favorable for the formation of deposits such as gold, copper, nickel, and chromite. Additionally, the country's diverse terrain provides different environments where minerals can accumulate and be mined.
Some mineral deposits found in the United States include gold in Nevada, copper in Arizona, and coal in Wyoming. These deposits are located in specific regions due to geological processes like sedimentation, volcanic activity, or tectonic movement that created conditions favoring the concentration and formation of these minerals. The unique combination of factors in these regions makes them conducive to the formation and accumulation of these deposits.
The Precambrian shield is rich in minerals due to its formation during the Precambrian era, which saw intense volcanic activity and the accumulation of various mineral deposits. The shield's geology, with its complex folding, faulting, and metamorphism, created optimal conditions for mineral formation and concentration over millions of years. Additionally, the erosion of surrounding rocks and the subsequent concentration of mineral deposits in the shield area further contributed to its rich mineral resources.
