designated chemicals sufficient for processing ore exist on the site as no milling occurs. <br /> There is one pallet of hydrated lime used prior to 2021 for dropping out metals and <br /> dissolved solids in the effluent coming from the portals. The only acids on site are one <br /> gallon of sulfuric acid used for recharging batteries and approximately one liter of dilute <br /> hydrochloric acid used by the geologists for identifying carbonate rocks. <br /> 5. Effluent discharge exceedances that occurred during the rehabilitation of the collapsed <br /> portal at the Idaho Tunnel have been mitigated by the treatment system installed at the <br /> end December 2021. This treatment system was designed by Environmental Solutions in <br /> conjunction with Graver Engineers. Black Fox Mining Consultants are monitoring <br /> sampling in an audit capacity for independent reporting to CDPHE. This treatment <br /> system is designed to eliminate total suspended solids (TSS)through filtration to 5 <br /> micron and total dissolved solids (TDS)removal by a cation adsorption media known as <br /> Metsorb. These respective analytical certificates have been provided to CDPHE to <br /> ascertain the success of the treatment system. Additionally, samples collected for a more <br /> comprehensive analytical suite per compliance reporting have had no exceedances to the <br /> metals limitations established in the NDPES permit from January 2022 through February <br /> 2022. Compliance samples for the first half of March have been collected and we are <br /> awaiting lab results. Additionally, wet samples for testing of the flathead minnow and <br /> daphnia are undergoing quarterly testing at this time. With no exceedances during the <br /> last eight weeks (re: weekly treatment system validation) for metals we are confident that <br /> the March 2022 sampling results will follow suit. <br /> 6. Effectually, discharge waters into Coon Track Creek meet the aquatic criteria in the <br /> NPDES permit. Post-mining reclamation will include sealing the portals from future <br /> discharge. With the lack of dissolution of the sulfides due to the high buffering capacity <br /> of the monzonitic host rock, future treatment post-reclamation will not be necessary. <br /> I state under penalty of perjury that the facts set forth above are true and correct. <br /> Further Affiant sayeth naught. <br /> JS N MULLER <br /> Page 2 of 3 <br /> CORG/3522586 0004.173273211 I <br />
