### APT Project RMG9362 Test Report – Smoky Valley Mine HCN Testing

page 1 1. Introduction
Air Pollution Testing, Inc. (APT) was contracted by Round Mountain Gold Corporation for source emissions test services conducted at the Smo ky Valley Mine facility near Round Mountain, Nevada.
The purpose of the emissions testing program was to quantify the emission levels of hydrogen cyanide (HCN) from the pregnant and barren tanks (P/B tanks) / carbon kiln stack and the electrowinning (EW) cell stack.
Contact personnel are provided in Table 1.1 below.

2. Methods
The test program was conducted in accordance with t he following U.S. Environmental Protection Agency source emissions test methods ref erenced in 40 CFR Part 60, Appendix A

. Method 1 – Sample and Velocity Traverses for Stati onary Sources
Method 2 – Determination of Stack Gas Velocity and Volumetric Flow Rate
Method 3 – Gas Analysis for the Determination of D ry Molecular Weight

3. Test Program Summary
APT provided all necessary equipment and labor for the determination of all emissions parameters detailed in Table 3.1 below. Integrated samples were collected for off-site analysis to determine the HCN content of the stack gas.
At both units, three 60-minute test runs were condu cted.

### Table 3.1: Sampling and Analytical Methods Summary

4. Test Method Details
Stack gas flow rate, diluent (oxygen and carbon dio xide) and hydrogen cyanide (HCN) emissions were determined in accordance with EPA me thods 1 – 4 and CTM-033 Draft Method XHCN.
Each sampling period consisted of conducting a temp erature and differential pressure traverse of the stack with a K-type thermocouple an d an S-type pitot tube. Concurrently, a gas sample was extracted at an isokinetic flow rate for a sixty minute period. The gas passed through a nozzle, a heated glass probe, acro ss a heated glass fiber filter, through a series of 4 chilled glass impingers, and through a calibrated dry gas meter. Please see Appendix 5 – Schematics for a diagram of the conditional test method sampl ing train. During each sampling run, a stack gas sample was co llected in a clean, leak-free Tedlar

page 3 bag for subsequent diluent analysis using an Orsat instrument.
Prior to sampling, the first two impingers were see ded with 100 milliliters of 0.1N sodium hydroxide (NaOH). The second impinger was empty. T he fourth impinger was seeded with 250 grams of dried silica gel.
The impingers were recovered along with NaOH rinses in a nalgene container for ion specific electrode (ISE) analysis.
As a QA/QC measure, a reagent blank plus a train bl ank at each stack were analyzed and HCN was not detected. Analysis was conducted by AL S Laboratory Group in Salt Lake City, Utah who have current AIHA certification for HCN analysis.

All of the above data were combined to calculate th e stack gas velocity and volumetric flow rate in units of feet per second (ft/sec), actual c ubic feet per minute (acfm), dry standard cubic feet per minute (dscfm), and pounds per hour (lb/hr). The stack gas HCN emissions were calculated in units of parts per million, dry volume basis (ppmvd) and pounds per hour (lb/hr).

5. Results
The results of the testing are presented in Tables 5.1 and 5.2. Any testing parameters not found in the tables may be found in Appendix 1 – Testing Parameters

. °F – temperature, measured in degrees Fahrenheit (° F)
dscfm – dry standard (68°F, 1 atmosphere) cubic fee t per minute

H 2 

### O (%vw) – stack gas water vapor content (wet volume percent)
lb/hr – pounds per hour
ppmvd – parts per million, dry volume basis
