Quality Control and Quality Assurance Measures
In addition to using field duplicates to monitor the quality of the indicator mineral data obtained from specific projects, ODM performs blind tests to ensure that the recovery rates for all targeted minerals are consistently in the 80% to 90% range. Furthermore, both the quality of the mineral separation and the overall mineralogy of the concentrate are visible at every stage of the concentration process, minimizing the potential for sample mix-ups, indicator mineral carryover between samples, and other potential contamination issues. For example, gold grains, which are the most important indicator mineral on many surveys, are more susceptible to inter-sample carryover than any other indicator mineral due to their very small size, but these grains are physically observed during the first stage of mineral concentration, tabling, and if anomalous concentrations are present, blank samples are tabled and carefully inspected for gold grains before the next project sample is processed.
Rock Sample Analysis

Rock sample analysis (gold by fire assay) was completed at Eastern Analytical Ltd. (Eastern), in Springdale NL. Samples were delivered in sealed bags directly to the lab by Sokoman Minerals' personnel. Eastern is an accredited assay lab that conforms to the requirements of ISO/IEC 17025. Eastern routinely inserts industry-accepted standards and blanks in all sample runs performed as well as completing random duplicate analysis. All core samples submitted for assay were saw cut by Sokoman personnel with one-half submitted for assay and one-half retained for reference. Samples were delivered in sealed bags directly to the lab by Sokoman personnel. Samples with possible visible gold were submitted for total pulp metallics and gravimetric finish. Total pulp metallic analysis includes: the whole sample is crushed to -10 mesh; then pulverized to 95% -150 mesh. The total sample is weighed and screened to 150 mesh; the +150 mesh fraction is fire assayed for Au, and a 30 g subsample of the -150 mesh fraction is fire assayed for Au; with a calculated weighted average of total Au in the sample reported as well. All reported assays are uncut.
