3. Ore Transportation. Ore is transported from the mine pit by haul trucks capable of carrying up to 400 tons to either the Crushing and Grinding section of the mine (Step 5) or directly to the Leach Pad (Step 7). Ore transportation operations can generate particulate matter (i.e., dust) that contains TRI chemicals.
