This from Red Chris regarding their silver inclusion...not legacy issues but nontheless just added

Vancouver - February 2, 2012 - Imperial Metals Corporation (III-TSX) reports a tonnage increase of 103% in the Measured and Indicated Resource at its Red Chris copper/gold deposit. The 2012 Technical Report(1) ("2012 Report") includes assay results from 62 diamond drill holes totalling over 69 thousand metres completed since the May 2010 resource update. The Measured and Indicated Resource increased to 8.89 billion pounds copper and 12.90 million ounces gold, while the Inferred Resource increased to 7.44 billion pounds copper and 11.35 million ounces gold, all at a 0.1% copper cut-off.

For the first time the 2012 Report provides a calculation of the significant silver resource contained in the Red Chris deposit. Historic drilling had not been consistently assayed for silver, however drilling completed by Imperial since 2007 was assayed for silver which has provided sufficient data to calculate a silver resource. There are 44.61 million ounces silver in the Measured and Indicated category and 47.04 million ounces silver in the Inferred category, all at a 0.1% copper equivalent cut-off.
