National Instrument 43-101 (NI 43-101) is a mineral resource classification scheme used for the public disclosure of information relating to mineral properties in Canada. The NI is a strict guideline for how public companies can disclose scientific and technical information about mineral projects on bourses supervised by the Canadian Securities Administrators. http://en.wikipedia.org/wiki/National_Instrument_43-101
