The above -grade components of the PSE circuit are planned to be constructed in 2012 <br />with subsequent submittal of Technical Revision to the Colorado Division of Reclamation, <br />Mining and Safety ( "DRMS ") that will address specific above - containment issues such as <br />solution type, quantity, chemistry and flow -path. This Technical Revision only addresses the <br />PSE liner containment system. <br />Operations at CC &V include the Arequa Gulch Valley Leach Facility ( "VLF ") and the <br />adsorption, desorption, and recovery ( "ADR ") facility. Both the VLF and ADR are under -lain by <br />synthetic liner systems. Process ( "barren ") solution is applied to the VLF using a network of <br />pipes, distribution tubing and drip emitters. The gold -laden process (or "pregnant ") solution is <br />collected in four discrete internal ponds or Pregnant Solution Storage Areas ( "PSSA's "). Each <br />PSSA services a particular area of the VLF and pregnant solution from each pond is pumped to a <br />
