Portions of the facility are subject to provisions of the Utah Department of Environmental Quality, Division of Air Quality (UDAQ) Approval Order (AO) DAQE- AN0103460058-20 and the Title V Operating Permit 3500030004. Testing was conducted to determine the emission rates of sulfuric acid (HzSO+), sulfur dioxide (SO2), ammonia (NH3), hydrogen chloride (HCl), and lead (Pb) at the exhaust of Hydrometallurgical Precious Metals Recovery (REF006). 1.1 Source and Control System Descriptions The RTK Refinery, located near the Smelter, receives anode copper produced at the Smelter and uses an electrolytic process to obtain the high purity cathode copper. The copper anodes from the smelter are submerged in tanks containing an electrolyte solution in batch operations. An electric current is applied to the tank for a l0-day period during which copper ions migrate from the anode to form a cathode of 99.99Yo pure copper. Precious metals (gold and silver) are recovered from the electrolytic refining slimes removed from the tanks in a series of hydrometallurgical operations. The Refinery copper refining process requires steam to maintain electrolyte temperatures and prevent the degradation of the electrolyte tanks as well as support the precious metals process. To supply steam, the Refinery operates a CHP unit as a primary source of steam and maintains two Refinery Boilers (Boilers #l and #2) as back up steam. Boiler #2 has recently been retrofit with an ultra-low NOx burner. Boiler #l will be decommissioned once stack testing is complete on Boiler #2. 1.2 Project Team Personnel involved in this project are identified in the following table. Table l-l: ProjectTeam 1.3 Site-Specific Test Plan & Notification Testing was conducted in accordance with the Site-Specific Test Plan (SSTP) submitted to UDAQ by RTK. 1,4 Test Program Notes As per guidance fiom the Operations Manager, Run I is based on an estimated moisture of 7%o.

Method descriptions are provided below while quality assurance/quality control data is provided in Appendix D. Table 3-1: Source Testing Methodology 3.1 U.S. EPA Reference Test Methods I and 2 - Sampling/Traverse Points and Volumetric Flow Rate The sampling location and number of traverse (sampling) points were selected in accordance with U.S. EPA Reference Test Method L To determine the rninimum number of traverse points, the upstream and downstream distances were equated into equivalent diameters and compared to Figure I - I and Figure 1-2 in U.S. EPA Reference Test Method l. Full velocity traverses were conducted in accordance with U.S. EPA Reference Test Method 2 to determine the average stack gas velocity pressure, static pressure and temperature. The velocity and static pressure measurement system consisted of a pitot tube and inclined manometer. The stack gas temperature was measured with a K-type thermocouple and pyrometer. The Oz and COu concentration were assumed to be ambient for molecular weight and volumetric flow rate calculations. Stack gas velocity pressure and temperature readings were recorded during each test run. The data collected was utilized to calculate the volumetric flow rate in accordance with U.S. EPA Reference Test Method 2. 3.2 U.S. EPA Reference Test Method 12 - Lead The lead (Pb) testing was conducted in accordance with EPA Reference Method 12. The complete sampling system consisted of a stainless steel nozzle, stainless steel probe, probe, heated quartz filter, gas conditioning train, pump, and calibrated dry gas meter. The gas conditioning train consisted of four (4) chilled impingers. The first and second impingers contained 100 mL of 0.1 N HNO:, the third was initially empty and the last impinger contained 200-300 grams of silica gel. The probe liner and filter heating systems were maintained at a temperature of 120 + l4"C (248 +25oF), and the impinger temperature was maintained at 20oC (68"F) or less throughout testing. Following the completion of each test run, the sampling train was leak checked at vacuum pressure greater than or equal to the highest vacuum pressure observed during the run and the contents of the impingers were measured for moisture gain. The quartz filter was carefully removed and placed into container l. The probe and nozzle were rinsed and brushed three (3) times with 0. I N HNO: using a non-metallic brush and these rinses were placed in container 2. The front half of the filter holder was rinsed three (3) times with 0.1 N HNO: and these rinses were added to container 2. The contents of impingers 1,2,and 3 were placed in container 4. Impingers 1,2,and 3 along with the filter supporl, back half of the filter holder and all connecting glassware were triple-rinsed with 0.1 N HNO: Parameter U.S. EPA Reference Test Methods NoteslRemarks Volumetric Flow Rate I &.2 Full Velociw Traverses Lead 12 lsokinetic Sampling Moisture Content / Sulfuric Acid / Sulfur Dioxide / Ammonia / Hvdrosen Chloride 320 FTIR - Continuous Sampling AST-2024- l 032-00 I RTK - Magna, UT Page 3-l pulhrpEr lr lllllO/rl Source Test Reporl Testing Methodolog,t and these rinses were added to container 4. All containers were sealed, labeled, and liquid levels marked for transport to the identified laboratory for analysis. 3.3 U.S. EPA Reference Test Method 320 - Moisture Content / Sulfuric Acid / Sulfur Dioxide / Ammonia / Hydrogen Chloride The concentrations of moisture content, sulfuric acid, sulfur dioxide, ammonia, and hydrogen chloride were determined in accordance with U.S. EPA Reference Test Method 320. Each source gas stream was extracted at a constant rate through a heated probe, heated filter and heated sample line and analyzed with a MKS MultiGas FTIR operated by a portable computer. The computer has FTIR spectra of calibration gases stored on the hard drive. These single component calibration spectra are used to analyze the measured sample specha. The gas components to be measured were selected from the spectra library and incorporated into the analytical method. The signal amplitude, linearity, and signal to noise ratio were measured and recorded to document analyzer performance. A leak check was performed on the sample cell. The instrument path length was verified using ethylene as the Calibration Transfer Standard. Dynamic spiking was performed using a certified standard of the target compound or appropriate surrogate in nitrogen with sulfur hexafluoride blended as a tracer to calculate the dilution factor. All test spectra, interferograms, and analytical method information are recorded and stored with the calculated analy,tical results. The quality control measures are described in Section 3.4. 3.4 Quality Assurance/Quality Control - U.S. EPA Reference Method 320 EPA Protocol 1 Calibration Gases - Cylinder calibration gases used met EPA Protocol 1 (+l- 2%) standards. Copies of all calibration gas certificates can be found in the Quality Assurance/Quality Control Appendix. After providing ample time for the FTIR to reach the desired temperature and to stabilize, zero gas (nitrogen) was introduced directly to the instrument sample port. While flowing nitrogen the signal amplitude was recorded, a background spectra was taken, a linearity check was performed and recorded, the peak to peak noise and the root mean square in the spectral region of interest was measured and a screenshot was recorded. Pollowing the zero gas checks, room air was pulled through the sample chamber and the line width and resolution was verified to be at 1879 cm-1, the peak position was entered and the FWHH was recorded (screenshot). Following these checks, another background spectra was recorded and the calibration transfer standard (CTS) was introduced directly to the instrument sample port. The CTS instrument recovery was recorded and the instrument mechanical response time was measured. Next, stack gas was introduced to the FTIR through the sampling system and several scans were taken until a stable reading was achieved. The native concentration of our surrogate spiking analyte as recorded. Spike gas was introduced to the sampling system at a constant flow rate S 10% of the total sample flow rate and a corresponding dilution ratio was calculated along with a system response time. Matrix spike recovery spectra were recorded and were within the + 30o/o of the calculated value of the spike concentration that the method requires. The matrix spike recovery was conducted once at the beginning of the testing and the CTS recovery procedures were repeated following each test run. The corresponding values were recorded.

Portions of the facility are subject to provisions of the Utah Department of Environmental Quality, Division of Air Quality (UDAQ Approval Order (AO) DAQE- AN0103460058-20 and the Title V Operating Permit 3500030004. Testing was conducted to determine the emission rates of sulfuric acid (HzSOa) and ammonia (NH:) at the exhaust of Hydrometallurgical Silver Production Exhaust Stack (REF007). 1.1 Source and Control System Descriptions The RTK Refinery, located near the Smelter, receives anode copper produced at the Smelter and uses an electrolytic process to obtain the high purity cathode copper. The copper anodes from the smelter are submerged in tanks containing an electrolyte solution in batch operations. An electric current is applied to the tank for a 10-day period during which copper ions migrate from the anode to form a cathode of 99.99Yo pure copper. Precious metals (gold and silver) are recovered from the electrolytic refining slimes removed from the tanks in a series of hydrometallurgical operations. The Refinery copper refining process requires steam to maintain electrolyte temperatures and prevent the degradation of the electrolyte tanks as well as support the precious metals process. To supply steam, the Refinery operates a CHP unit as a primary source of steam and maintains two Refinery Boilers (Boilers #l and #2) as back up steam. Boiler #2 has recently been retrofit with an ultra-low NOx burner. Boiler #l will be decommissioned once stack testing is complete on Boiler #2. 1.2 Project Team Personnel involved in this project are identified in the following table.

Table 3-l: Source Testing Methodology Parameter U.S. EPA Reference Test Methods Notes/Remarks Volumetric Flow Rate 1&2 Full Velocity Traverses Moisture Content / Sulfuric Acid / Ammonia 320 FTIR - Continuous Sampling 3.1 U.S. EPA Reference Test Methods I and 2 - Sampling/Traverse Points and Volumetric Flow Rate The sampling location and number of traverse (sampling) points were selected in accordance with U.S. EPA Reference Test Method l. To determine the minimum number of traverse points, the upstream and downstream distances were equated into equivalent diameters and compared to Figure I -2 in U.S. EPA Reference Test Method I . Full velocity traverses were conducted in accordance with U.S. EPA Reference Test Method 2 to determine the average stack gas velocity pressure, static pressure and temperature. The velocity and static pressure measurement system consisted of a pitot tube and inclined manometer. The stack gas temperature was measured with a K-type thermocouple and pyrometer. The Oz and COz concentration were assumed to be ambient for molecular weight and volumetric flow rate calculations. Stack gas velocity pressure and ternperature readings were recorded during each test run. The data collected was utilized to calculate the volurnetric flow rate in accordance with U.S. EPA Reference Test Method 2. 3.2 U.S. EPA Reference Test Method 320 - Moisture Content / Sulfur Dioxide / Ammonia The concentrations of moisture content, sulfur dioxide, and ammonia were determined in accordance with U.S. EPA Reference Test Method 320. Each source gas stream was extracted at a constant rate through a heated probe, heated filter and heated sample line and analyzed with a MKS MultiGas FTIR operated by a potable computer. The computer has FTIR spectra of calibration gases stored on the hard drive. These single component calibration spectra are used to analyze the measured sample spectra. The gas components to be measured were selected from the spectra library and incorporated into the analytical method. The signal amplitude, lineariry, and signal to noise ratio were measured and recorded to document analyzer perfonnance. A leak check was performed on the sample cell. The instrument path length was verified using ethylene as the Calibration Transfer Standard. Dynamic spiking was performed using a ceftified standard of the target compound or appropriate surrogate in nihogen with sulfur hexafluoride blended as a tracer to calculate the dilution factor. All test spectra, interferograms, and analytical method information are recorded and stored with the calculated analytical results. The quality control measures are described in Section 3.3. 3.3 Quality Assurance/Quality Control - U.S. EPA Reference Method 320 EPA Protocol I Calibration Gases - Cylinder calibration gases used met EPA Protocol 1 (+l- 2%) standards. Copies of all calibration gas certificates can be found in the Quality Assurance/Quality Control Appendix. AST-2024-1032-002 RTK - Magna, UT Page 3-l pill6rpe IECIINICAL GROt]P Source Tesl Report Testins Methodolop After providing ample time for the FTIR to reach the desired temperature and to stabilize, zero gas (nihogen) was introduced directly to the instrument sample port. While flowing nitrogen the signal amplitude was recorded, a background spectrum was taken, a linearity check was performed and recorded, the peak to peak noise and the root mean square in the spectral region of interest was measured and a screenshot was recorded. Following the zero gas checks, room air was pulled through the sample chamber and the line width and resolution was verified to be at 1879 cm-l, the peak position was entered and the FWHH was recorded (screenshot). Following these checks, another background spectra was recorded and the calibration transfer standard (CTS) was introduced directly to the inshument sample port. The CTS instrument recovery was recorded and the instrument mechanical response time was measured. Next, stack gas was introduced to the FTIR through the sampling system and several scans were taken until a stable reading was achieved. The native concenffation of our surrogate spiking analyte as recorded. Spike gas was introduced to the sampling system at a constant flow rate < l0o/o of the total sample flow rate and a corresponding dilution ratio was calculated along with a system response time. Matrix spike recovery spectra were recorded and were within the + 30Yo of the calculated value of the spike concentration that the method requires. The matrix spike recovery was conducted once at the beginning of the testing and the CTS recovery procedures were repeated following each test run. The corresponding values were recorded.

Portions of the facility are subject to provisions of the Utah Department of Environmental Quality, Division of Air Quality (UDAQ) Approval Order (AO) DAQE- AN0103460058-20 and the Title V Operating Permit 3500030004. Testing was conducted to determine the emission rate of particulate matter less than l0 microns (PMl0) at the exhaust of Gold/Silver Recovery Baghouse (REF0l0). Front half PM measurements were considered PMl0 emissions for demonstration with compliance limits. l.l Source and Control System Descriptions The RTK Refinery, located near the Smelter, receives anode copper produced at the Smelter and uses an electrolytic process to obtain the high purity cathode copper. The copper anodes from the smelter are submerged in tanks containing an electrolyte solution in batch operations. An electric current is applied to the tank for a l0-day period during which copper ions migrate from the anode to form a cathode of 99.99o/o pure copper. Precious metals (gold and silver) are recovered from the electrolytic refining slimes removed from the tanks in a series of hydrometallurgical operations. The Refinery copper refining process requires steam to maintain electrolyte temperatures and prevent the degradation of the electrolyte tanks as well as support the precious metals process. To supply steam, the Refinery operates a CHP unit as a primary source of steam and maintains two Refinery Boilers (Boilers #l and #2) as back up steam. Boiler #2 has recently been retrofit with an ultra-low NOx burner. Boiler #l will be decommissioned once stack testing is complete on Boiler #2. 1.2 Project Team Personnel involved in this project are identified in the following table. Table l-1: Project Team 1.3 Site-Specific Test Plan & Notification Testing was conducted in accordance with the Site-Specific Test Plan (SSTP) submitted to UDAQ by RTK.

Method descriptions are provided below while quality assurance/quality control data is provided in Appendix D. Table 3-1: Source Testing Methodology 3.I U.S. EPA Reference Test Methods I and 2 - Sampling/Traverse Points and Volumetric Flow Rate The sampling location and number of traverse (sampling) points were selected in accordance with U.S. EPA Reference Test Method l. To determine the minimum number of traverse points, the upstream and downstream distances were equated into equivalent diameters and compared to Figure I - I in U.S. EPA Reference Test Method I . Full velocity traverses were conducted in accordance with U.S. EPA Reference Test Method 2 to determine the average stack gas velocity pressure, static pressure and temperature. The velocity and static pressure measurement system consisted of a pitot tube and inclined manometer. The stack gas temperature was measured with a K-type thermocouple and pyrometer. The Oz and COz concentration were assumed to be ambient for molecular weight and volumetric flow rate calculations. Stack gas velocity pressure and temperature readings were recorded during each test run. The data collected was utilized to calculate the volurnetric flow rate in accordance with U.S. EPA Reference Test Method 2. 3.2 U.S. EPA Reference Test Method 4 - Moisture Content The stack gas moisture content was determined in accordance with U.S. EPA Reference Test Method 4. The gas conditioning train consisted of a series of chilled impingers. Prior to testing, each impinger was filled with a known quantity of water or silica gel. Each impinger was analyzed gravimetrically before and after each test run on the same analytical balance to determine the amount of moisture condensed. 3.3 U.S. EPA Reference Test Methods 5 and 202 -Total Particulate Matter The total particulate matter (filterable and condensable PM) testing was conducted in accordance with U.S. EPA Reference Test Methods 5 and202. The complete sampling system consisted of a stainless steel nozzle, glass-lined probe, pre-weighed quartz filter, coil condenser, un-weighed Teflon filter, gas conditioning train, pump and calibrated dry gas meter. The gas conditioning train consisted of a coiled condenser and four (4) chilled impingers. The first and second impingers were initially empty, the third contained 100 mL of de-ionized water and the last impinger contained 200-300 grams of silica gel. The un-weighed 90 mm Teflon filter was placed between the second and third impingers. The probe liner heating system was maintained at a temperature of 248+25"F, and the impinger temperature was maintained at 68'F or less throughout testing. The temperature of the Teflon filter was maintained greater than 65oF but less than or equal to 85oF.

Condensate was collected in the first dry impinger, therefore the front-half of the sample train (the nozzle, probe, and heated pre-weighed filter) was removed in order to purge the back-half of the sample train (coil condenser, first and second impingers and CPM filter). A glass bubbler was inserted into the first impinger. If needed, de-ionized ultra-filtered (DIUF) water was added to the first impinger to raise the water level above the bubbler, then the coil condenser was replaced. Zero nitrogen was connected to the condenser, and a 60-minute purge at 14 liters per minute was conducted. After the completion of the nitrogen purge the impinger contents were measured for moisture gain. The pre-weighed quartz filter was carefully removed and placed in container l. The probe, nozzle and front half of the filter holder were rinsed three (3) times with acetone to remove any adhering particulate matter and these rinses were recovered in contain er 2. All containers were sealed, labeled, and liquid levels marked for transport to the identified laboratory for filterable particulate matter analysis. The contents of impingers I and2 were recovered in container CPM Cont. #1. The back half of the filterable PM filter holder, the coil condenser, impingers I and 2 and all connecting glassware were rinsed with DIUF water and then rinsed with acetone, followed by hexane. The water rinses were added to container CPM Cont. #1 while the solvent rinses were recovered in container CPM Cont. #2. The Teflon filter was removed from the filter holder and placed in container CPM Cont. #3. The front half of the condensable PM filter holder was rinsed with DIUF water and then with acetone, followed by hexane. The water rinse was added to container CPM Cont. # I while the solvent rinses were added to container CPM Cont. #2. All containers were sealed, labeled and liquid levels marked for transport to the identified laboratory for condensable particulate matter analysis.

After speaking with Mike Swensen, my silver caster, we recall that we did not have enough sands for a silver cast on 3/15 so we did a "silver melt" in the south furnace to simulate as best we could a silver cast for the baghouse stack test. The actual silver cast, S32, was completed on3lt7.

Can you send me a quick email with a summary of the material that was produced that day? I need this summary for the report that will be submitted. I have included an example that we attached to the report the last time we tested the baghouse.
