Unclear prose on my part, strannick let me clarify.  Both statements you quote refer to Galena, not Caladay.  For many years both CDE and HL owned Galena under a JV with Asarco as operator, however the last years when the Galena belonged soley to CDE and CDE was the operator, CDE sucked the marrow from the bone and did not do much of any exploration or sustaining CAPEX, which resulted in the shaft collapse.  Galena's production under CDE was sourced solely from mechanized production of the Cu/Ag 72 vein (4.4mm oz Ag/yr for at least 8-10 years) and no exploraton was done to build reserves beyond the 72.  When USA bought Galena, the 72 on the near side of the fault had been mined out by CDE (like the Silver vein the 72 has a drop down extension of the on the far side of the fault, no doubt USA will locate it in the future just as they located the extension of the Silver Vein) and the only reserves that could be mined were those above the shaft collapse, namely the narrow vein Pb/Ag on the 2400 level.  There was some Cu/Ag reserves on the books too, located below the shaft collapse, however, those stopes could not be opened on account of lack of access and sufficient infrastructure such as hoisting capacity.  Also keep in mind that unlike Drumlummon, in the Silver Valley if a drift is not maintained it collapses in on itself after as little as 4 to 5 years of neglect.  The shaft at Galena was collapsed for over a decade so after fixing it, even though USA knew where certain high grade Cu/Ag stopes were, they couldnt just go in and mine those stopes since extensive infrastructure redevelopment was necessary just to access those stopes as well as for safety reasons.  It is only since November 2010 that USA even had the money to invest in such redevelopment.  This work takes time, and I think we are very close to seeing more of these older Cu/Ag stopes reopened along with the Cu/Ag Silver Vein.
