Making rare earth element disclosure transparent and compliant: Getting the most out of other organizations’ practices
James Whyte - Feb 2011
When prices for rare earth metals rose sharply over the last five years, we saw junior mining companies take on rare earth projects and seek financing to explore them on the equity markets.

Technical reports: key principles to help avoid common deficiencies
Deborah McCombe and Craig Waldie - Feb 2008
To potentially avoid NI 43-101 compliance issues with technical reports, there are several key principles that should be kept in mind by qualified persons when preparing technical reports.
Reasonable prospects for economic extraction
Greg Gosson and Larry B. Smith - Dec 2007
The important thing is to be reasonable (not conservative, or excessively liberal) in the choice of parameters. The resource estimator should try to identify that material that has “reasonable prospects” but may not be reserves at this time.
Preparing content of a technical report - reasonably relying on others
Greg Gosson - Nov 2007
Item 5: Reliance on Other Experts of the Technical Report Form allows a qualified person to rely on a report, opinion or statement of a legal or other expert, who is not a qualified person, for information concerning legal, environmental, political or other issues and factors relevant to the technical report.
Quality control reporting requirements by the mining industry
Armando Simón and Greg Gosson - Sep 2007
Geological quality control procedures are intended to monitor precision and accuracy of the assay data, as well as possible sample contamination during preparation and assaying.
Deborah McCombe - Aug 2007
The involvement of a Qualified Person (QP) in the preparation of scientific and technical information on a mineral property is a cornerstone of National Instrument 43-101, Standards of Disclosure for Mineral Projects (NI43-101).
Dates in technical reports
Deborah McCombe - Jun 2007
There are a number of important dates that must be disclosed when a Qualified Person (QP) is preparing a technical report for securities purposes. The dates are discussed in NI43-101 and the Form of the Technical Report, NI43-101F1.
Making sense of consents
Greg Gosson and Deborah McCombe - May 2007
Under Canadian Securities law, qualified persons (QPs) are called upon to provide their written consent to the scientific and technical content in disclosure documents being filed by public mining and exploration companies. Most often the consent is provided by the qualified persons that prepared a technical report under NI 43-101 Standards of Disclosure for Mineral Projects. In this article, we explain the different triggers for consents under securities law, the timing for filing, and the required content of the consent.
Is your NI43-101 technical report compliant?
