A potential drawback is that investors are exposed to idiosyncratic risks associated with owning the stock of a particular company.
The principal minerals of silver ores are argentite, pyrargyrite, polybasite, proustite, stephanite, and silverbearing galena. The ores often contain native silver. Silver ore deposits are most closely associated with granitoids, as well as with subvolcanic and volcanic rocks, occurring either in these rocks or in the surrounding rocks.
Silver ore can be mined at level 20 Mining, providing 40 Mining a silver rock is mined, it will take 60 seconds for it to respawn. Smelting silver ore will turn it into a silver bar, giving Smithing experience. The bar can then be crafted into various types of jewellery through the Crafting skill at a furnace, rather than at an anvil like other metallic bars.
