ALASKA 99503 Mr. John Leverson Division of Oil & Gas State of Alaska 3001 Porcupine Drive Anchorage, Alaska 99504 Dear John' Re: Standard Oil Co. of CalifOrnia #1 Nimiuk I took the liberty of having two small chips of core from the interval 6299- 6305 analyzed by Chemical and Geological Laboratories of Alaska, Inc. These chips were a brown translucent mineral which is associated with the dark dOlomites of this core. Test results showed this mineral to be a zinc sulfide containing 56% zinc, 2.1% iron and 20%+ acid insoluble residue which resembled sulfur. Some reations with HCL was noted and was probably from a dolomite portion although sample was not tested for calcium and magnesium~ 'It is my opinion from visual examination and.laboratory test that.this is an impure sphalerite.
