(2) The difference between what we report as "Metal Production" and "Metal Sold" is attributable to the difference between the quantities of metals contained in the concentrates we produce versus the portion of those metals actually paid for according to the terms of our sales contracts. Differences can also arise from inventory changes related to shipping schedules, or variances in ore grades and recoveries which impact the amount of metals contained in concentrates produced and sold.
