trace element analysis of rock sample 2004Z233B


236 samples were analyzed for gold on a 30-gram split using Atomic Absorption Spectroscopy after Fire Assay. 6 samples containing greater than 1000 ppb gold wer re-analyzed with a gravimetric finish following fire assay fusion. 46 samples containing greater than 15 ppb gold were assayed for mercury by Cold Vapor Atomic Absorption Spectroscopy after HCl:HNO3 (3:1) acid digestion. 233 samples were analyzed for trace elements by Inductively Coupled Plasma - Atomic Emission Spectroscopy methods following HF-HNO3-HClO4 acid digestion with HCl leach. This method of digestion is possibly incomplete for some elements and may result in lower analytical results for certain elements. Sample 04SAH115A exhibits possible Au nugget effect. 2nd grav [...]
