Talk:National Instrument 43-101

Relevance

The article is tagged with some commentary about relevance, the NI 43-101 was a direct response to incidents such as the Bre-X scandal, and is a key part of the global mining industry; 43-101 and JORC are the de-facto standards to which global mineral property disclosure is measured. News articles discussing this and similar regulatons are as follows: https://www.theglobeandmail.com/report-on-business/the-number-of-canadian-listed-companies-that-operate-in-remote-countries-has-soared-so-has-the-challenge-of-regulating-them/article18140487/

Except for the first line

Except for the first line the article is fairly correct. But NI43-101 is not a resource classification scheme. Many non-technical people misuse the term in print as well as conversation, but it really is a scheme or template of disclosure. Nothing more.

Resource Estimates

Can someone include how resource estimates are calculated as per NI 43-101 standards 66.16.158.235 (talk) 21:08, 9 December 2008 (UTC)

NI 43-101 is not a tool for calculating resource estimates. It is a tool for "qualifying" those estimates. Making a "proper" resource estimate is not straight forward and relys on a lot of commodity specific information and experience. It can be a lengthy process to do properly. This is something that can not be easily addressed here, nor should it. See Mineral resource classification for a bit more info. Turgan ^Talk 15:19, 10 December 2008 (UTC)

i'd also like to point out that NI 43-101 is NOT a resource classification scheme and not equivalent to JORC or SAMREC, it is a scheme of public disclosure. The resource classification scheme as well as how compliant resources are estimated is dictated by The Canadian Institute of Mining, Metallurgy and Petroleum (CIM) —Preceding unsigned comment added by 86.0.3.211 (talk) 08:31, 30 June 2010 (UTC)

Major update March 09

I went and updated this. The comparisons with the JORC code are worthwhile, in my opinion, because the NI 43-101 and JORC Codes are, in practise, quite different beasts. It is also worth considering that the layperson is not actually well served by a 250 page report which is mandated to be published in full on the TSX-V by the company, at the behest of the CSA. Sure, the uglies are all there, but the reader is not likely to become well informed about the economics and the sensibility or otherwise of investing.

We should therefore consider trying to link this in with investing pages as this is basically securities oversight tool, as Turgan says. Rolinator (talk) 08:16, 20 March 2009 (UTC)

Thank you for doing this. It definately needed it. Turgan ^Talk 04:01, 21 March 2009 (UTC)

No problem. Rolinator (talk) 08:00, 27 March 2009 (UTC)

Resources for understanding NI 43-101 and mineral disclosure

There doesn't seem to be a ton of really quickly-available information on this. After looking around, I found a very long powerpoint presentation Mineral Project Disclosure Standards: Understanding NI 43-101. One of my biggest questions is how to approach the cut-off grades, and there's a self-published website article on that. I imagine that ultimately the best information is going to be in books; The mining valuation handbook : mining and energy valuation for investors and management, Mining Explained, and An introduction to cut-off grade estimation look promising.

Proposed rule changes in 2010

In April 2010, the Canadian Securities Administrators announced a press release about their proposed, which is mainly about "whether to keep, modify or eliminate the short form prospectus trigger for technical reports". The proposed rule is BCN2010/18. Martindale has a summary (Proposed Changes to National Instrument 43-101 - Standards of Disclosure for Mineral Projects). The press release says this is the first "major change" since 2001. However, I noticed in the BC Notices that there were a couple updates in 2005 (BCN 2005/59) and BCN 2010/49).

Other important dates should probably be added as well, such as date of proposal.
