Client, Strongbow Capital Ltd, has generously agreed to allow the American Institute of Minerals Appraisers and
Ellis International Services to place this report in the public domain for educational purposes.
Particular features of this report include:
- The valuation process and valuation reporting were developed to abide by the International Valuation Standards and the USA's USPAP;
- Analysis of transactions in many countries;
- The Transaction (Sales) Analysis section includes extraction of market discount information;
- The Sales Comparison Adjustment Grid includes adjustments for operating cost and country risk, among its many adjustments;
- Use of probability scenarios with the NPV/DCF method;
- Use of the Stock Market Entity Value Extraction method. (The method is tentatively classified as a Cost Approach Method
in this report. In 2007, the IVSC's Extractive Industries Expert Group proposed that this method be classified as a Sales Comparison Approach method
when used for valuation of the real property component of minerals and petroleum assets. A decision is expected from the Standards Board of the IVSC
in the Extractive Industries Technical Paper in 2008);
- Reconciliation of estimates derived by a number of methods.
