In order to model the full cradletogate production process for primary zinc, a key assumption is the combination of the zinc mining and concentration sites with the zincsmelting sites. Zinc concentrate is sold as a commodity, so depending on market forces, a zinc smelter may process zinc concentrate from a variety of mines.

Small scale surface mining started in the 1970s until the start of largescale surface mining in 1991, leading eventually to the start in 1994 of the CCV Cresson Project. Today, CCV is a lowgrade, openpit operation. Ore processing. The ore is treated using a valleytype, heapleach process with activated carbon used to recover the gold.
