No historic data on quality control at Anaconda's analytical laboratory in Yerington was found. The laboratory was not independent of Anaconda Company.
8.4.1 Yerington
Lion CG implemented a quality assurance and quality control assay protocol whereby either one blank or one standard is inserted with every ten samples into the assay stream. Additional check samples were submitted to ALS Minerals Laboratories in Sparks, Nevada. Core duplicates were not used.
Lot failure criteria were established as any standard assaying beyond two standard deviations of the expected value, or any blank assay greater than 0.015 percent TCu.
Geochemical reference standards are listed in Table 8.2. Blanks were also purchased from Moment Exploration Geoservices, two were used: Si.Blank.21.01 and Si.Blank.21.03. The accepted values were 0.005% total copper.
