ON EDIT : birchmountain.com Analytical Method Development In March, 1999, Birch Mountain initiated an in-house program to develop analytical methods to resolve inconsistencies between SEM/EMP imaging and precious metals analysis, and to address the problem of repeatability. By adjusting experimental conditions, by carefully recording experimental conditions, and by systematically varying key parameters, Birch Mountain is deliberately striving to identify and control the variables causing the erratic results. We are using Birch Mountain's laboratory, and facilities and analytical instrumentation available in the Department of Geology at the University of Calgary. Significant results from Birch Mountain's recent in-house work are given in Table 5. Atomic absorption measurements carried out by Birch Mountain at the University of Calgary utilized three point standard additions calibration and deuterium arc background correction. Table 5.

We can not yet explain this lack of repeatability. It is unlikely, however, that contamination is responsible because we obtain similar results using different methods and laboratories. Results for sample BJ98-008 are summarized in Table 6. Table 6. Summary of assay and leach results, 1998 bulk sample BJ98-008.
