Bureau of Mines hard rock mlÏneral pulp samples from the Colville Mining District: ';Vest Kivliktort Mountain (CMD5601; AV91-20110.0) of Howard Pass Quad., 1Cady (CMD4183; AV91-20127.0) of Killik River Quadrangle, 1Cady (CMD5455; A V91-20110.0) of Killik River Quadrangle, and Story Creek (CMD5432; AV91-20109.0) of Howard Pass Quadrangle. Received 1 February 1996 Total of 1 page in report Alaska Geologic Materials Center Data Report No. 264 DATE: January 29, 1996 TO: Dr. John Reeder FROM: Melanie Werdon REGARDING: U. S. Bureau of Mines geochemical samples. The following table shows the analytical results of X-ray fluorescence analyses I ran, compared to the values reported by the U. S. Bureau of Mines by ICP for various elements. The XRF analyses confirm my observation that there was interference between high Zn and Pb with the elements Mo and Bi. The Sb values are similar enough that there is likely no interference problem. Sn values are comparable except for sample 5455. The reason for this is not clear.
