Figures 1 throuc~ 20 are included <br />at this time. Additional figures, being developed at Orchard Valley, will be <br />provided as they are completed and all will be suLmitted by May 31, 1994. A list <br />of figures will be provided as well once the figures are finalized. The order <br />figures are presented has been changed for the 1993 AHR and is generally in <br />accordance with Table 1 as are the rest of the data presented in the report. <br />'Ihe new database installation purchased by Cyprus remains unavailable to Orchard <br />Valley at this time and therefore, no statistical analyses of 1993 data is <br />included in the report. Water quality data for the 1993 AFQ2 was manually <br />ca~ared to the statistical summaries provided in the 1992 AHR. A consulting <br />firm has been hired to work the remaining bugs out of the database system and <br />this work should be finalized soon. Orchard Valley will share a database <br />installation with the Plateau mine in Utah and will, as soon as the system <br />becmnes available, travel to Utah to input 1993 data and to correct errors and <br />omissions discovered in the 1992 data. Any statistical information required by <br />the Division will be delayed until this process can be arnq~leted. <br />If you have any questions or cononents, please contact me at 303-527-4135. Thank <br />you for your cooperation. <br />CYPRUS ORCf~eRD VALLEY GOAL OORPORATION <br />Karl C.
