wikepedia The purpose of National Instrument 43-101 is to ensure that misleading, erroneous or fraudulent information relating to mineral properties is not published and promoted to investors on the stock exchanges overseen by the Canadian Securities Authority.
The NI 43-101 was created after the Bre-X scandal to protect investors from unsubstantiated mineral project disclosures.
"The gold reserves at (Bre-X's) Busang were alleged to be 200 million ounces (6,200 t), or up to 8% of the entire world's gold reserves at that time. However, it was a massive fraud and there was no gold. The core samples had been faked by salting them with outside gold. An independent lab later claimed that the faking had been poorly done, including the use of shavings from gold jewelry. In 1997, Bre-X collapsed and its shares became worthless in one of the biggest stock scandals in Canadian history."[2]
The promulgation of a codified reporting scheme makes it more difficult for fraud to occur and reassures investors that the projects have been assessed in a scientific and professional manner. However, even properly and professionally investigated mineral deposits are not necessarily economic, nor does the presence of a NI 43-101-, JORC- or SAMREC and SAMVAL-compliant CPR or QPR necessarily mean that it is a good investment.
Similarly, the publication of a complex technical report with all the inherent jargon, technical wording and abstract geological, metallurgical and economic information may not actually significantly advantage an investor who is not able to fully nor properly understand the content or importance of this information. In this way the NI 43-101 may not serve the interests of those it is designed to protect[dubious – discuss]—the retail investors who may easily misinterpret such information. Because of this, many investors hire independent geology consultants to review the reports for them.
