person must have 5 years experience : The requirement for a Qualified Person in the NI 43-101 is different from that required by the JORC Code, and the SAMREC and SAMVAL Codes, wherein the person must have 5 years experience relevant to the deposit type or style of mineralization but is otherwise similar in terms of who may or may not sign off on such a document. The Qualified Person must declare whether a qualified person has verified the data disclosed, including sampling, analytical and test data underlying the information or opinions contained in the written disclosure; a description of how the data was verified and any limitations on the verification process; and an explanation of any failure to verify the data. http://en.wikipedia.org/wiki/National_Instrument_43-101
