Abstract. K‐Ar age determinations were carried out on vein‐ and rock‐forming minerals from five vein‐type tin‐polymetallic ore deposits of the Oruro mining district in the central part of the Bolivian tin belt.

Three holes were drilled to test outcropping silverleadzinc carbonate veins at the "Vetas" area, a target drilled for the first time in 2018. Highgrade silver intercepts occur with visible 'ruby silver' minerals and associated base metal sulphides in multiple vein structures.

The ancient Greeks used bronze, a mix of tin and copper, for their weapons and tools. Later, iron was used because it produced harder tools and weapons. Athens found a large amount of silver in the mines at Laurium. At its peak, Athens had over 20,000 slaves mining at Laurium.

In fact, it is one of the largest producers of copper in the world. By 1920, it had yielded over 8,000,000,000 pounds of copper, more than 400,000,000 ounces of silver, and 2,000,000 ounces of gold, also much zinc and smaller amounts of arsenic, lead and manganese.

Nov 11, 2013· Prospectors need to focus on finding ore shoots in veins. Nearly all veins in gold districts will have some gold and silver, but the values are alway erradic. Thus if you were able to follow a vein for some distance you will likely find trace amounts of gold at most locations.

Many of the veins are distinguished from the usual type of ore body by the occurrence of abundant tourmaline. The, metals produced are chiefly silver, lead, gold, and zinc, with some copper. The younger veins are essentially preciousmetal deposits. They are mainly fissure veins but include some disseminated deposits of low grade.
