On November 7, 2013, the TSX issued staff notice 2013-0003 providing guidance with respect to the meaning of the “economically interesting grades” requirement for Advanced Properties.  While this is helpful, a question which remains, as per our December 13, 2012 bulletin,  Lack of Infrastructure Impacts TSX Mining Listing Policy,  is whether the availability of infrastructure is a risk factor among many others, and should therefore be a matter of disclosure.  Fasken Martineau adds its views in our recent bulletin,  Commentary on TSX Staff Notice Regarding “Economically Interesting Grades” and “Infrastructure”, to what should be an ongoing discussion of a subject that is of considerable importance to all parties concerned in the development of resources in areas of Canada including the Ring of Fire and northern Quebec.
