EXHIBIT G WATER INFORMATION(CONT) blue are outside the permit area (which is owned by Cannon Land Company) . Cannon owns 12 wells . Of the 4 highlighted wells not owned by Cannon, one (1) well is a deep well (highlighted dark blue) and three (3) wells are shallow wells drawing water from the surface aquifer (highlighted light blue or green) . The green highlighted well is the only surface residential and the light blue are irrigation wells . Prior to exposing groundwater or installing a slurry wall liner in any Phase, a well survey will be performed on any wells within 200 feet of that Phase not owned by Cannon Land Company. The only well that will not be tested will be the Pacheco well, because it is in excess of 600 feet deep and will not be affected by potential surface impacts due to mining. L.G. Everist will attempt to obtain for each well to be tested the following data, in addition to whatever basic well construction data is currently available: • Total well depth • Depth to static water level, • Depth of pump intake • Conduct pump test to determine well yield (subject to SEO Regulations) • Conduct analytical sampling of all Domestic Drinking Water parameters for any residential wells . Data was collected in June and July 2021 at L.G. Everist' s expense for one McPeak well and two Sakata wells . The data was provided to DRMS and the well owner on September 23, 2021, a copy of the report is provided in the APPENDIX. If a well owner chooses not to allow the permittee access to collect the above data, they will be provided with a form that they can sign and date to document that they have been provided with an opportunity to have their well characterized at the permittee' s expense, but have chosen to decline to participate. L.G. Everist, Inc. has installed 14 piezometers (a.k. a. Monitoring Wells) around the mine. Their locations are shown on the maps and on MAP EXHIBIT G-1 WELL MAP. L.G. Everist started data collection in October 2019 and will do monthly readings throughout the life of the mine. We will provide a summary of the data yearly with the Annual Report . Post Reclamation Any slight groundwater mounding and shadowing associated with the slurry wall sealed portions of the pit are not anticipated to produce any adverse impacts to adjacent L.G.
