The reductions in sales, income (loss) from operations,and depreciation, depletion, and amortization at the Lucky Friday segment for 2012  compared to 2011 and 2010 are due to the temporary suspension of production at the Lucky Friday mine during 2012. At the end of 2011, MSHA  began a special impact inspection at the Lucky Friday mine which resulted in an order to remove built-up cementitious material from the Silver Shaft. In  response, we submitted a plan to MSHA and received approval to remove the material, and this work commenced in the first quarter of 2012. In  addition, the plan included removal of unused utilities, construction of a water ring to prevent ice from forming in the winter, the installation of a metal  brattice, repair of shaft steel, and installation of a new power cable, all of which should improve the shaft’s functionality and possibly improve the shaft’s  hoisting capacity. The Silver Shaft work was completed in early 2013, and limited production at the Lucky Friday has recommenced. We anticipate a  ramp-up in mine output during the year, as additional productions areas of the mine come on line, until we return to full production levels in mid-2013.  However, the timing of resuming full production levels may vary from our current estimates. The smelter contracts related to treatment of Lucky Friday  concentrates have been suspended during the care-and-maintenance period based on  force majeure . Once the Silver Shaft work was completed  down to the 4900 foot level, we commenced work on a haulage way bypassing an area at the 5900 level impacted by a rock burst in December 2011,  and the bypass was completed in early 2013. In addition to work on the Silver Shaft, other significant surface and underground capital programs have  been planned, including restart of the #4 Shaft sinking in early 2013 and surface infrastructure and mill upgrades. During 2012, we incurred $25.3  million in non-capitalized expenses, including $6.3 million in depreciation, depletion, and amortization, which is reported in  Lucky Friday suspension- related costs  on the  Consolidated Statements of Operations and Comprehensive Income . The following is sales information by geographic area based on the location of smelters (for concentrate shipments) and the location of parent  companies (for doré sales to metals traders) for the years ended December 31, 2012, 2011 and 2010 (in thousands):  Sales of products for 2012 also include a net loss of $1.3 million on financially-settled forward contracts for lead and zinc contained in our  concentrate sales. 2011 sales included a net gain of $7.1 million and 2010 sales included a net loss of $3.0 million on the contracts. See Note 10 for  more information.
