Stibnite was a precious trisulfide mineral of antimony and contained 71.69 percent antimony in it. Antimony was a metalloid element that people rarely heard about, but it had wide applications, especially in creating aerospace materials and materials for batteries used to store renewable energy. It also worked as a hardener for alloys, as it possessed the property to increase the hardness when mixed with another metal. This property became the reason for its heavy usage by the military. There was just 0.0001 percent of antimony in the Earth's crust, making it much rarer than tungsten.
In short, the mining and applications of stibnite affected the economic and military developments of the country, making it one of the most precious minerals and a treasure trove of wealth.
