Subject: Study of Waste Rock Slope Stability
Proposed New Waste Rock Depository Olerud Tract
Spruce Pine,North Carolina
Shield Project No. 1130122-04
Dear Mr. Mickleborough:
Shield Engineering has conducted an analysis of the stability of the Olerud Tract proposed waste
rock depository area in Spruce Pine, North Carolina.
PROJECT INFORMATION
The attached Figure I shows the topography for the proposed waste rock depository area under
consideration. The original topographic contours are shown in green on the figure while the
proposed slope contours are shown in blue. Shield Engineering initially chose seven profiles at
various locations for the study of the waste rock slope stability. These are also indicated on Figure
1 as Slope Profile l through 7. From these seven slope profiles. Shield selected Profile 1 for
analysis because it had the steepest proposed slope of 2.02H:1 V and a height differential from the
top of proposed waste rock mound to the top of insitu soils of 42 feet.
ANALYSIS METHODOLOGY
Shield used two different software tools for the analyses: GSTABL7 (Modified Bishop Method)
and STABLPRO (Modified Bishop Method). For each analysis run, Shield analyzed the slope
stability for global and localized failures within each program.
In email communications, with you, Todd Mickleborough, Shield understands that 5 core holes,
or exploratory sites, at the subject property revealed that the existing layer of topsoil was
approximately 4 feet thick and sits atop bedrock in the form of Gneiss. Shield created the slope
profile models in GSTABL7 and STABLEPRO using homogenous strata of waste rock, existing
soils,and bed rock. Figure 2 shows the slope profile where waste rock is in green, existing soils in
yellow, bedrock in blue, and the blue line represents a potential water table.

Quartz Corporation provided Shield with the document listed below for technical review to aid in v
our analysis.Based on our review of that document, Shield notes that the following soil parameters
were used to some degree in our analysis.
1. Slope Stability — West Dump Waste Dump— produced by Golder Associates and dated
May 2009.
a. unit weight,y= 110 pef, friction angle, =35'and cohesion, c' = 100 psf
The above soil parameters from the Golder report were based on laboratory testing results of two
test pits with two samples taken from each pit. The Golder report states that "there are boulders
throughout the matrix" and the soil data summary table indicates that the sample type were bulk
samples.
For the initial sensitivity analysis, Shield used the above soil parameters for the waste rock based
on the laboratory test results in the Golder report. The soil parameters used in the model for the
existing surface soils were tacit weight, y= 110 pef, friction angle, � = 25' and cohesion, c' = 0
psf.The soil parameters used in the model forbedrock were unit weight,y= 150 pef,friction angle.
�=40'and cohesion,c' =0 psf. The results for the initial sensitivity analysis are listed in Table 1
as GSTABL7 Slope Profile 1. GSTABL7 is a 2-dimensional limit equilibrium slope stability
program with the capability of running numerous scenarios on soillrock types and configurations.
Shield used generally conservative parameters and configurations in order to model varying
conditions that might occur.
So/
Shield also performed slope stability analysis with an increased unit weight of y= 130 pef for the
waste material to estimate the waste material with the boulders included. Additionally, Shield
analyzed slope stability with and without a water table parallel to the existing ground surface five
feet into the waste material layer,
CONCLUSIONS
The results of the analyses are attached in Table 1. The results for both programs were the
essentially the same, therefore, only the GSTABL results are shown in Table 1 along with the
output files included as attachments.
Typically,the engineering standard for an acceptable factor of safety of 1.5 is used for steady-state
conditions. The results from the analyses indicate a minimum factor of safety of 1.588 for local
slope stability and 1.681 for global slope stability which are greater than the acceptable minimum.
