Segment Reporting Disclosure [Text Block] | Note 6. Business Segments We are currently organized and managed in four segments, which represent our operating units: the Greens Creek unit, the Lucky Friday unit, the Casa Berardi unit, and the San Sebastian unit. General corporate activities not associated with operating units and their various exploration activities, as well as discontinued operations and idle properties, are presented as “other.” Interest expense, interest income and income taxes are considered general corporate items, and are not allocated to our segments. The following tables present information about reportable segments for the three months ended March 31, 2017 and 2016 (in thousands):

The sales and income (loss) from operations amounts reported above include results from our Lucky Friday segment. The Lucky Friday mine is our only operation where some of our employees are subject to a collective bargaining agreement, and the most recent agreement expired on April 30, 2016. On February 19, 2017, the unionized employees voted against our contract offer and on March 13, 2017 went on strike and have been on strike since that time. Production at the Lucky Friday has been suspended since the start of the strike. Costs related to care-and-maintenance of the mine during the strike period are reported in a separate line item on our condensed consolidated statement of operations and totaled $1.6 million in the first quarter of 2017. We cannot predict how long the strike will last or whether an agreement will be reached. As a result of the strike or other events related to labor at the Lucky Friday, operations at Lucky Friday could continue to be disrupted, which could adversely affect our financial condition and results of operations.
