C-81-044: 1996 ANNUAL HYDROLOGY REPORT <br />Dear Mr. Walker: <br />Please find enclosed duplicate copies of the 1996 Annual Hydrology Report for Cyprus Empire <br />Corporation's Eagle No. 5 and No. 6 mines. Figures 2, 11, 12, and 20 are not available at this time and <br />will be submitted as soon as possible under separate cover. These figures reside on the Aulocad system <br />at the Empire mine and scheduling conFlicts havF.to.date not allowed the drafting technician to access this <br />system in order to revise these figures for the 1996 AHR. <br />In responding to questions pertaining to the 1995 Annual Hydrology Report, Mr. James G. Nalven of <br />James G. Nalven Consulting identified a data set for the No. 9 Mine well which contained water quality <br />constituent values markedly atypical as compared to other samples and analyses collected from this site. <br />This data was determined to have been erroneously associated with the No. 9 Mine well. For the 1996 <br />Annual Hydrology Report, this data set has been deleted from the database and is not included in the <br />historical statistical summary provided. The enclosed Table A details the information which has been <br />deleted from the database. <br />Thank you for your cooperation in this matter. Please contact me at (970) 870-2730 if you have any <br />questions or require additional information. <br />CYPRUS EMPIRE CORPORATION <br /> <br />Karl C.
