Unprocessed ore typically trades at a discount of 20% - 30% of the LME spot price. Below is a hypothetical example of a 10mt load of cassiterite that contains 60% Sn with the current LME spot price of Tin at $25,000/mt. The purchase price will be a 20% discount on the LME spot price. 10,000kg x 60% = 6,000kg (6mt) Sn (total amount of Sn)
