CLIMATE INFORMATION EXHIBIT K
The following climate information is presented for Revenue Mine. The data available was from the
Ouray, CO CO -OP weather station operated for the Western Regional Climate Center of the
National Oceanic and Atmospheric Association. The Revenue Mine is located at an average
elevation of 10,680', while the Ouray weather station is at an elevation of 7784'. A analysis of the
temperature maps for Colorado (Figures K -2A through K -2C) shows that the temperatures
measured in Ouray are close enough to those at the mine to use as the mine climate. The same
cannot be same of precipitation.
The annual precipitation of 40" per year was gathered from a map produced by the U.S. Department
of Agriculture Natural Resource Conservation Service and is shown in Fig K -1. The average
monthly precipitation was calculated by a ratio average annual precipitation (40" per year) at
Revenue Mine to the average annual precipitation (23" per year) of the Ouray, CO station
multiplied by the average monthly precipitation for the Ouray, CO station.
