The sample preparation and assay procedure was as follows:• All samples were dried in a locked, heated container, either within the sample bagor on a steel tray. Dried samples were transferred to the sample preparation area.• Each sample was crushed in a jaw crusher to 95% of -10 mesh (<2 mm) and thendivided by a Jones riffle splitter into two one-kilogram samples. The first samplewas preserved as a geological coarse reject that was kept sealed in plasticcontainers; the second sample was passed on for further processing. In 2005, thecrushing procedure was modified to conform to Russian requirements. Thisinvolved the implementation of two crushing stages: In the first stage, the jawcrusher was set to 90-95% passing <2 mm, and for the second stage (secondcrusher) the jaws were set to >85% passing <1 mm.• The sample was pulverized to 90% -150 mesh (.005 mm) in a LM2 bowl and puckpulverizer. The pulverized sample (pulp) was split into four 250 g samples thatwere placed in paper sample envelopes. One pulp sample went for fire assay, onewas kept as a laboratory reject, and two were retained as geology duplicates. Allpulps are stored in locked containers.For each twenty samples, one additional sample was split from both the crusher andpulverizer splits to ensure compliance with laboratory quality control specifications.All equipment was air-washed between samples. A blank silica sample was run as acleaning medium every twenty samples, and after samples with visible gold or strongmineralization.
