Groundwater Monitoring - New Horizon 2 Mine
In anticipation of the New Horizon Mine's migration to the west - northwest and toward an area not
currently being monitored for groundwater parameters, WFC submitted a minor revision
application (MR41) to DMG for the installation of six groundwater monitoring wells, three up dip
(northeast corner) and three down dip (southwest corner) of the projected future areas of
disturbance. See Map 2.04.7 -1 -A. WFC has also submitted a technical revision applications
(TR -38, TR -47) to revise the hydrological monitoring program as follows:
• Begin monitoring of the six new groundwater wells (GW -N41, GW -N42 and GW -N43 up
dip, and GW -N44, GW -N45 and GW -N46 down dip). Table 2.04.7 -1 shows the frequency
and parameters to be monitored.
