Many pyrite and pyrrhotite minerals contain gold, which is often recovered when extracting copper from lode vein deposits. The purity of gold is stated in terms of fineness and carats (ct). Fineness is defined as the parts per 1000. For example gold with a fineness of 800 means it is 80% pure gold. Alternatively, gold that is pure is 24ct.
These are a real treat for gold prospectors and collectors as well, and are often valued at a premium due to their beauty and rarity. Hard rock mining, also known as lode mining, is obviously the best method for finding gold specimens since you are mining the true source of the gold by following veins of high grade ore into the mountain.
