The Casino copper-gold-molybdenum deposit is located in west-central Yukon.  The Casino deposit is unique in that unlike most of the rest of Canada, the land around it has not been affected by recent continental glaciers. Samples of stream sediment and water were collected at 22 sites in September 2017 from streams near the deposit in order to determine the amount of metal elements present in the sediment and water.  Ten elements are studied in further detail in this report; gold, copper, molybdenum, silver, antimony, arsenic, zinc, lead, bismuth, and manganese.  Using statistics, we determined that Casino samples were similar to stream sediment samples from the same area collected in 1986 and reanalyzed in 2014.  The Casino samples were also analyzed with a portable X-ray fluorescence device and the results compared with other types of analysis.
