EXECUTIVE SUMMARY
A laboratory testing program has been conducted to determine the geotechnical characteristics of the Casino tailings materials. The tailings sample provided by Casino Mining Corporation for testing represents Non Acid Generating (NAG) Whole Tailings. This sample was used to generate representative samples of tailings Cyclone Overflow (fine tailings) and Cyclone Underflow (sand) materials. A sample of Potentially Acid Generating (PAG) tailings (with pyrite) was not available for testing at this time.
The test program included index testing to enable geotechnical classification of the materials, and slurry settling, air drying, consolidation and permeability testing to determine the characteristics of the Whole Tailings and Cyclone Overflow following deposition and for a range of conditions (representative of expected field conditions).
The Whole Tailings material can generally be described as non-plastic sand and silt with trace clay. The particle size distribution of the Whole Tailings sample comprises approximately 58% fine sand, 35% silt and 7% clay. The Cyclone Overflow sample was generated to a target particle size distribution with approximately 75% fines (silt and clay fractions). The resulting cyclone overflow material comprised approximately 23% sand, 69% silt and 8% clay (77% total fines). Similarly, the Cyclone Underflow sample was generated for a target particle size distribution with a maximum of 15% fines. The resulting cyclone underflow material comprised approximately 85% sand, 13% silt and 2% clay (15% total fines).
The specific gravity of the tailings solids was determined to be 2.70 for the Whole Tailings sample, 2.71 for the Cyclone Overflow sample, and 2.80 for the Cyclone Underflow sample.
Undrained settling, drained settling and air drying tests were carried out on slurry samples of the Whole Tailings and Cyclone Overflow. The Whole Tailings slurry was tested at a target solids content of 55%, corresponding to the current design value. The Cyclone Overflow slurry was tested at three solids contents (approximately 25%, 40% and 55%) to provide information on the effect of initial slurry solids content on the settling and permeability characteristics of the material and the effect on water recovery and achieved density. Slurry settling (sedimentation) tests provide an estimate of the density to which the tailings slurry will settle in a sub-aqueous environment, under undrained and drained conditions. These tests provide an indication of the tailings dry density achieved in a storage facility after settling and before any significant consolidation or air drying occurs. Air drying tests were carried out on the tailings samples to determine the effect of air drying after initial slurry settling and removal of supernatant water.
The undrained settled dry density of the Whole Tailings slurry is 1.0 tonnes/m3. The drained settled dry density is 1.09 tonnes/m3. The undrained settled dry density of the Cyclone Overflow varies from 0.8 tonnes/m3 (initial slurry solids content of 25%) to 1.07 tonnes/m3 (initial solids content of 55%). The drained settled dry density varies from 0.95 tonnes/m3 to 1.2 tonnes/m3. The dry densities achieved for drained settling are approximately 10% to 20% higher than those for undrained settling, with the larger increase occurring for Cyclone Overflow slurry with lower initial solids content.
Air drying of the tailings materials produces a significant increase in dry density over those from the undrained and drained settling tests. The highest densities are achieved for slurries with higher initial solids content (dry densities of 1.35 tonnes/m3 for the Whole Tailings and 1.44 tonnes/m3 for

the Cyclone Overflow sample with an initial slurry solids content of 55%). As expected, the amount of water recovered is highest for tailings slurries with lower initial solids content (higher initial water content). Supernatant water recovery from settled Cyclone Overflow with an initial slurry solids content of 25% is expected to be approximately 75%.
Laboratory tests carried out to determine the consolidation and permeability characteristics of the Whole Tailings and Cyclone Overflow included Slurry Consolidometer testing, Low Stress Slurry Consolidation tests and Falling Head Permeability tests (conducted on settled tailings after completion of drained settling tests). Relationships between coefficient of consolidation, void ratio and vertical coefficient of permeability to effective stress have been developed for both of these tailings materials. Calculated coefficients of consolidation for the Whole Tailings range from 100 m2/year at very low stresses to over 1000 m2/year at high stresses. Calculated coefficients of consolidation for the Cyclone Overflow range from 25 m2/year at very low stresses to over 1000 m2/year at high stresses.
Measured vertical permeability values for the Whole Tailings and Cyclone Overflow decrease with increasing effective stress. The permeability of the Whole Tailings ranges from approximately 1 x 10-4 cm/sec at low stresses (representing unconsolidated or fresher tailings near surface) to about 1 x 10-6 cm/sec at high stresses, corresponding to a reduction in void ratio (representing more consolidated or deeper tailings within the deposit). Similarly, the permeability of the Cyclone Overflow ranges from approximately 5 x 10-5 cm/sec at low stresses to about 1 x 10-6 cm/sec at high stresses.
Compaction, shear strength and permeability tests were carried out on the laboratory manufactured Cyclone Underflow sample. The shear strength and permeability tests were carried out over a large range of confining stresses to examine the influence of high confining stresses (corresponding to a large dam height) on the strength and permeability values. The optimum moisture content of the Cyclone Underflow sample was determined to be 16.7% and the maximum dry density was 1,559 kg/m3. The shear strength of the cyclone sand is defined by an average effective friction angle of 36 degrees and zero cohesion. The potential strength characteristics of the cyclone sand over a large stress range have been examined by comparison of the laboratory test data to published information on the non-linear strength characteristics of similar granular materials (angular sands). This information suggests that the effective friction angle of the cyclone sand may be greater than 36 degrees at low confining stresses but potentially lower at very high stresses. However, the laboratory test results for the Cyclone Underflow sample suggest that there is no apparent loss of strength at the higher stresses, over the stress range tested.
Permeability values determined for the Cyclone Underflow show a general trend of reducing permeability with increasing confining stress. This decrease is the result of the decrease in material density and potentially from the generation of finer particles due to particle crushing. However, the results do not appear to indicate a dramatic decrease in permeability at high stresses, which would be indicative of significant particle crushing and changes to the fines content of the material. The permeability of the Cyclone Underflow ranges from approximately 2 x 10-3 cm/sec at lower stresses to about 5 x 10-4 cm/sec at high stresses (approximately 3000 kPa). Extrapolation of these results suggests that the permeability of the Cyclone Underflow will remain greater than 1 x 10-4 cm/sec at very high stresses of about 4000 to 5000 kPa.

INTRODUCTION 1 –
This report presents the details and findings of a laboratory testing program to determine the geotechnical characteristics of the Casino tailings materials. The laboratory testing was carried out at the Knight Piésold laboratory in Denver, Colorado.
A sample of the Casino tailings was provided by Casino Mining Corporation for testing. The tailings sample represents Non Acid Generating (NAG) whole tailings. This sample was used to generate representative samples of Cyclone Overflow (fine tailings) and Cyclone Underflow materials. A sample of Potentially Acid Generating (PAG) tailings (with pyrite) was not available for testing at this time.
The Cyclone Overflow sample was generated to a target particle size distribution with approximately 75% fines (silt and clay fractions). Similarly, the Cyclone Underflow sample was generated for a target particle size distribution with a maximum of 15% fines. The target particle size distributions used for generation of the cyclone overflow and underflow materials were based on the anticipated material products from cycloning of the Casino whole tailings and information provided by cyclone manufacturers.
The laboratory test program included index testing to enable geotechnical classification of the materials, and slurry settling, air drying, consolidation and permeability testing to determine the characteristics of the Whole Tailings and Cyclone Overflow following deposition and for a range of conditions (representative of expected field conditions). The following is a list of the geotechnical tests conducted on the Whole Tailings and Cyclone Overflow samples:
Index Tests
Specific Gravity of solids
Atterberg Limits (Plastic and Liquid Limits), and
Particle size distribution by mechanical sieve and hydrometer.
Slurry Settling and Air Drying Tests
Undrained Settling
Drained Settling (with Falling Head permeability measurement), and
Air drying.
Slurry Consolidation Tests
Slurry Consolidometer Test (with permeability measurement), and
Low Stress Slurry Consolidation (Burette) Test.
The slurry settling (sedimentation) tests provide an estimate of the density to which the tailings slurry will settle in a sub-aqueous environment, under undrained and drained conditions. These tests provide an estimate of expected tailings density in a storage facility after settling and before any significant consolidation or air drying occurs. The air drying test provides the geotechnical characteristics of the tailings for expected conditions on exposed beaches following deposition. The effect of air drying on moisture loss and tailings density is determined by this test.
The slurry consolidometer test is used to determine the consolidation, compressibility and permeability characteristics of the tailings over a wide range of confining pressures (typically corresponding to expected conditions in the field). These parameters can be used to determine the

amount and rate of consolidation, seepage rates, settlement and density increase for the tailings. The slurry consolidation cylinder test provides a measure of the consolidation characteristics of the tailings at very low effective stresses (representing freshly deposited tailings immediately following settling).
The following is a list of the geotechnical tests conducted on the Cyclone Underflow sample:
Index Tests
Specific Gravity of solids, and
Particle size distribution by mechanical sieve and hydrometer.
Strength and Permeability Tests
Compaction (Proctor) Test
Tri-axial Shear Strength, and
Flexible Wall Permeability.
The compaction test provide information on the expected density of the cyclone sand following placement as compacted sand fill for embankment construction. The shear strength test provides information on the strength of the compacted sand over a range of confining stresses, and is used for embankment stability assessment. Similarly, the Flexible Wall permeability test provides information on the expected permeability of the cyclone sand fill over a range of confining stresses. The permeability characteristics of the cyclone sand are an important consideration in the design of free-draining cyclone sand embankment dams.
It is recommended that laboratory testing is also carried out on a representative sample of PAG tailings for future design studies.

INDEX TESTS 2 –
GENERAL 2.1
Index testing was carried out on the tailings solids for the Whole Tailings sample and the laboratory generated Cyclone Overflow (fine tailings) and Cyclone Underflow (cyclone) samples.
The Specific Gravity, Atterberg Limits (Plastic and Liquid Limits), and particle size distribution (screen and hydrometer) of the tailings were determined. These tests provide a measure of the type and condition of the material, specifically the particle density, composition (size and distribution) and plasticity characteristics. The index properties can provide a relationship to material structural properties, including compressibility, permeability and strength.
A summary of the tailings index test results is presented in Table 2.1. Detailed results of the index tests are included in Appendix A.
PARTICLE SIZE DISTRIBUTION 2.2
Mechanical sieve and hydrometer particle size analyses were carried out on each of the tailings samples in accordance with ASTM standard D422 procedures. The hydrometer analysis is used to determine the silt and clay fraction particle sizes.
The particle size distribution of the Whole Tailings sample comprises approximately 58% fine sand, 35% silt and 7% clay. The Cyclone Overflow sample was generated to a target particle size distribution with approximately 75% fines (silt and clay fractions). The resulting cyclone overflow material comprised approximately 23% sand, 69% silt and 8% clay (77% total fines). Similarly, the Cyclone Underflow sample was generated for a target particle size distribution with a maximum of 15% fines. The resulting cyclone underflow material comprised approximately 85% sand, 13% silt and 2% clay (15% total fines).
The particle size distributions of the three tailings samples tested are presented on Figure 2.1.
SPECIFIC GRAVITY 2.3
The specific gravity of the tailings solids was determined in accordance with ASTM standard D854. The measured specific gravity is 2.70 for the Whole Tailings sample, 2.71 for the Cyclone Overflow sample, and 2.80 for the Cyclone Underflow sample.
ATTERBERG LIMITS (PLASTICITY) 2.4
The Atterberg Limits (Plastic and Liquid Limits) of the tailings samples were determined in accordance with the ASTM standard D4318 test procedure. Examination of each of the three sample indicated that the tailings materials are non-plastic. A Liquid Limit (LL) of 24% was determined for the Cyclone Overflow sample. The liquid limit is the moisture content at which a soil material starts to exhibit liquid behaviour.
MATERIAL CLASSIFICATION 2.5
The Whole Tailings material can generally be described as non-plastic Silty Sand with trace Clay, and classifies as SM (sand with non-plastic fines) under the Unified Soil Classification System.

SLURRY SETTLING & AIR DRYING TESTS 3 –
GENERAL 3.1
Undrained Settling, Drained Settling and Air Drying tests were carried out on the Whole Tailings and Cyclone Overflow samples.
The Whole Tailings slurry sample was prepared at an initial target solids content of approximately 55%, corresponding to the current design discharge value for the project. For the Cyclone Overflow the tests were conducted on slurry samples prepared at initial solids contents of approximately 25%, 40% and 55%. The design solids content of the cyclone overflow material was unknown at the time of testing. Testing the slurry at different solids contents provides information on the effect of slurry solids content on the settling and permeability characteristics of the material, and also the effect on water recovery and achieved density.
Slurry settling (sedimentation) tests provide an estimate of the density to which the tailings slurry will settle in a sub-aqueous environment, under undrained and drained conditions. These tests provide an indication of the tailings dry density achieved in a storage facility after settling and before any significant consolidation or air drying occurs. The actual settled density achieved in the field, prior to commencement of consolidation or air-drying, is likely to be within the range bounded by the densities obtained from the Undrained and Drained Settling tests.
Air Drying tests are carried out to determine the effect of air drying after initial slurry settling and removal of supernatant water, thereby simulating expected conditions on exposed tailings beaches following deposition.
Complete results of the slurry settling and air drying tests are included in Appendix A.
UNDRAINED SETTLING TESTS 3.2
The Undrained Settling test estimates the density to which the tailings slurry will settle in an undrained sub-aqueous environment.
Undrained Settling tests were performed by placing the slurry into a one litre graduated cylinder and recording the rate of settling and change in volume of the tailings sample as supernatant water bleeds to the surface. The final dry density of the settled solids is determined once the change in settled volume remains essentially constant.
The Whole Tailings and Cyclone Overflow slurries took one to two days to complete undrained settling. The settled dry densities increase with increasing initial slurry solids content. For the Whole Tailings sample the settled dry density is 1.0 tonnes/m3. The undrained settled dry density of the Cyclone Overflow sample is 0.80 tonnes/m3 for an initial slurry solids content of 25% solids, 0.99 tonnes/m3 for 40% solids, and 1.07 tonnes/m3 for 55% solids.
The initial and final settled dry densities achieved for the Undrained Settling tests are included in Table 3.1. Also included in Table 3.1 are the corresponding initial and final void ratios (ratio of voids volume to volume of solids) and the corresponding total water recovery from the slurry (as a percentage of total water in initial slurry) after settling is complete.

DRAINED SETTLING TESTS 3.3
The Drained Settling test provides an indication of the tailings dry density that will be achieved from settling with free drainage from the base of the sample.
The Drained Settling tests were performed by placing the tailings slurry into a one litre graduated cylinder with provision for bottom drainage and recovery of downward seepage. The rate of settling and change in volume of the sample is recorded with time, as supernatant water bleeds to the surface and drains from the base. Supernatant water is continually decanted from the surface, whenever possible, to minimize development of a vertical seepage gradient across the sample. The final dry density of the settled solids is calculated once the change in settled volume remains constant.
Similar to the Undrained Settling tests, the tailings slurries took one to two days to complete drained settling. For the Whole Tailings sample, the settled dry density is 1.09 tonnes/m3 (initial slurry solids content of 55%). For the Cyclone Overflow sample, the settled dry densities are 0.95 tonnes/m3 for an initial slurry solids content of 25%, 1.13 tonnes/m3 for 40% solids, and 1.20 tonnes/m3 for 55% solids.
The initial and final settled dry densities achieved for the Drained Settling tests are included in Table 3.1. Also included in Table 3.1 are the corresponding initial and final void ratios and the corresponding total water recovery from the slurry after settling is complete.
Permeability measurements of the tailings samples were taken after completion of the Drained Settling tests. Details and results of Falling Head permeability tests conducted on the drained settled samples are provided in Section 4.4.
AIR DRYING TESTS 3.4
The Air Drying tests were conducted by allowing the tailings slurry samples to settle and air dry under monitored conditions in order to investigate the relationship between density, moisture content, and degree of saturation in a drying environment. Partially saturated conditions are achieved as the amount of moisture loss through evaporation exceeds the reduction in volume of the sample. An absolute relationship between dry density and moisture content exists up to a point at which the degree of saturation falls below 100%. At this stage negative pore pressures (suction pressures) develop and act to further consolidate the sample (reducing the volume). Further drying below a limiting moisture content (the shrinkage limit) produces no further consolidation and the dry density at this point represents the maximum that can be achieved by air drying of the material.
The Air Drying tests are performed by introducing a sample of tailings slurry into a one litre container with no underdrainage and allowing the slurry to settle while decanting supernatant water. Routine measurements are taken of sample weight and volume. Once the slurry has completely settled and all surface water has been removed, air drying commences causing moisture loss and consolidation. An evaporation control, subjected to the same drying environment as the slurry sample, is also monitored in order to estimate the rate and amount of evaporation (from a free water surface) applied to the sample. However, in the field, greater evaporation rates and correspondingly faster consolidation rates may occur than in the laboratory due to the effects of wind, advection and solar radiation.

The Whole Tailings and Cyclone Overflow samples required approximately one to two weeks to complete air drying (achieving the shrinkage limit) under laboratory conditions. For the Whole Tailings sample the air dried dry density was 1.35 tonnes/m3 (initial slurry solids content of 55%). For the Cyclone Overflow sample the air dried dry densities achieved were 1.29 tonnes/m3 for an initial slurry solids content of 25%, 1.43 tonnes/m3 for 40% solids, and 1.44 tonnes/m3 for 55% solids.
The dry densities achieved for each of the Air Drying tests are included in Table 3.1. Also included in Table 3.1 are the corresponding initial and final void ratios after settling and air drying is complete.
Complete results of the Air Drying tests are provided in Appendix A, including plots showing the relationship between tailings dry density, volume reduction, moisture content, degree of saturation and evaporation.
SUMMARY OF SETTLING AND AIR DRYING TESTS 3.5
The settled dry density of the Whole Tailings is approximately 1.0 tonnes/m3 for undrained settling and 1.09 tonnes/m3 for drained settling. The dry density achieved for drained settling is approximately 10% higher than for undrained settling. Supernatant water recovery from settled Whole Tailings with an initial slurry solids content of 55% is expected to be approximately 26% for undrained conditions and about 43% for drained settling conditions.
Using the results of the Undrained and Drained Settling tests, the final dry densities and corresponding total water recovery for the Cyclone Overflow slurry are plotted as functions of initial slurry solids content on Figures 3.1 and 3.2, respectively.
Figure 3.1 illustrates the higher dry density for slurries with higher initial solids content, and the increase in dry density for drained settling compared to undrained settling. The undrained settled dry density of the Cyclone Overflow varies from approximately 0.8 to 1.07 tonnes/m3. The drained settled dry density varies from approximately 0.95 tonnes/m3 to 1.2 tonnes/m3. The dry densities achieved for drained settling are approximately 10% to 20% higher than those for undrained settling, with the larger increase occurring for slurries with lower initial solids content.
The final dry densities from the Air Drying tests are also plotted on Figure 3.1. Air drying of the Cyclone Overflow material produces a significant increase in dry density over those from the Undrained and Drained Settling tests. The highest densities are achieved for slurries with higher initial solids content (up to a dry density of about 1.44 tonnes/m3 for an initial slurry solids content of 55%).
Figure 3.2 illustrates the relationship between total water recovery (supernatant water recovered from the tailings slurry) and initial solids content of the Cyclone Overflow slurry. As expected, the amount of water recovered is highest for slurries with lower initial solids content (higher initial water content). Supernatant water recovery from settled Cyclone Overflow with an initial slurry solids content of about 25% is expected to be approximately 75% or higher, depending on actual drainage conditions during settling.

SLURRY CONSOLIDATION AND PERMEABILITY TESTS 4 –
GENERAL 4.1
Laboratory tests have been carried out to determine the consolidation and permeability characteristics of the Whole Tailings and laboratory generated Cyclone Overflow. Material consolidation, compressibility and permeability (hydraulic conductivity) parameters derived from the laboratory testing can be used in design studies to determine the amount and rate of tailings consolidation, to predict seepage rates from and through the tailings, and to predict tailings settlements and density increase with time.
The consolidation and permeability parameters have been provided by Slurry Consolidometer testing, Low Stress Slurry Consolidation tests and Falling Head Permeability tests (conducted on settled tailings after completion of Drained Settling tests).
SLURRY CONSOLIDOMETER TEST 4.2
A specialized slurry consolidometer device was used to determine the consolidation, compressibility and permeability characteristics of the tailings over a range of effective confining stresses. The slurry consolidometer apparatus is designed to evaluate the consolidation characteristics of slurries that initially have high void ratios and high moisture contents at low effective stresses.
The tests were conducted by placing a slurry sample into the consolidometer and allowing the tailings to settle and consolidate under self weight. Confining stresses ranging from very low (about 14 kPa) to over 800 kPa were then applied in incremental loading stages. Routine measurements of settlement with time were recorded during each loading stage. Once settlement ceased or became negligible during loading the confining stress was increased to the next loading stage. The permeability of the tailings was measured at the end of each loading stage. Two-way drainage conditions were facilitated in the test. Detailed results of the testing are provided in Appendix A.
The results of the Slurry Consolidometer test were used to calculate the coefficient of consolidation (cv) for each loading stage. The coefficient of consolidation is a measure of the consolidation characteristics (rate of consolidation) of a material. A high coefficient of consolidation corresponds to a high rate of consolidation while a low value indicates a slow rate of consolidation. The coefficients of consolidation and void ratios determined for the tailings are presented for each loading stage in Table 4.1 for Whole Tailings and Table 4.2 for Cyclone Overflow. Calculated tailings dry densities and measured vertical permeability (kv) values are also included in Tables 4.1 and 4.2.
Coefficients of consolidation determined for the Whole Tailings and Cyclone Overflow are generally similar and increase with increasing effective confining stress, ranging from approximately 200 m2/year at low stresses to over 1000 m2/year at high stresses. Measured void ratios decrease from about 1.0 at low stresses to less than 0.7 at high stresses. Calculated values of the coefficient of consolidation and void ratio for the Whole Tailings are included on Figures 4.1 and 4.2, respectively. Calculated values of the coefficient of consolidation and void ratio for the Cyclone Overflow are included on Figures 4.3 and 4.4, respectively.

The calculated tailings dry density for each loading stage is included in Tables 4.1 and 4.2. The dry density of the tailings materials increases with increasing effective stress, with a value of about 1.6 tonne/m3 achieved at high effective stresses.
Measured vertical permeabilities for the Whole Tailings and Cyclone Overflow are included on Figures 4.5 and 4.6 respectively.
LOW STRESS SLURRY CONSOLIDATION TEST 4.3
The Low Stress Slurry Consolidation (burette) test provides a measure of the consolidation characteristics of the tailings at very low effective stresses (approximately 1 to 2 kPa), representing freshly deposited tailings immediately following initial settling. The test is used to estimate the coefficient of consolidation of the tailings at a very low effective stress (and corresponding high void ratio).
The test is carried out by introducing a pre-measured quantity of the tailings slurry sample into a one litre burette with the bottom stopcock closed. After initial settling (sedimentation) of the slurry, the bottom stopcock is opened to permit drainage and dissipation of pore pressures, causing an increase in the effective stress within the sample. Observations of the decrease in slurry volume (settlement) with time are recorded, and used to estimate the coefficient of consolidation. Estimates of initial and final sample void ratio, dry density, permeability and the corresponding effective stresses (due to the self-weight of the sample) are calculated.
Tests were conducted for both the Whole Tailings and Cyclone Overflow samples. A summary of the Low Stress Slurry Consolidation test results, including calculated values of void ratio, dry density, coefficient of vertical permeability and the coefficient of consolidation are presented in Table 4.3 for both samples. The calculated values of coefficient of consolidation are 100 m2/year for the Whole Tailings and 25 m2/year for the Cyclone Overflow. Calculated permeability values are approximately 2 x 10-4 cm/sec for the Whole Tailings and 3 x 10-5 cm/sec for the Cyclone Overflow.
Detailed results of the testing are included in Appendix A.
FALLING HEAD TESTS ON SETTLED TAILINGS 4.4
Falling Head permeability tests were performed on the settled tailings samples, after completion of each of the drained settling tests (see Section 3.3). This test provides an indication of the vertical permeability of the tailings material at very low effective stresses (approximately 1 kPa) and corresponding low density (high void ratio). In practice, the permeability will decrease as consolidation increases the density and reduces the void ratio.
The test is conducted by applying water to the surface of the settled tailings, imposing a vertical gradient across the sample. The drainage rate and drop in water level were recorded with time to provide a value of vertical permeability (hydraulic conductivity). The test is repeated several times to provide an average permeability value.
The average permeability values provided by the Falling Head tests for each of the drained settling test samples are included in Table 3.1. The average permeability measured for the Whole Tailings is approximately 1 x 10-4 cm/sec. The average permeability measured for the Cyclone Overflow ranges from approximately 3 x 10-5 cm/sec to 6 x 10-5 cm/sec.

Detailed results of the testing are included in Appendix A.
SUMMARY OF CONSOLIDATION AND PERMEABILITY TESTS 4.5
Calculated coefficients of consolidation for the Whole tailings range from about 100 m2/year at very low stresses (representing freshly settled tailings) to over 1000 m2/year at high stresses (representing consolidated tailings at depth within the deposit). This indicates that the rate of tailings consolidation has the potential to increase as effective stress conditions increase with depth, but will be dependent on in situ pore water pressure conditions. The relationship between coefficient of consolidation and effective stress for the Whole Tailings is shown on Figure 4.1, including calculated coefficient of consolidation values provided by the Slurry Consolidometer test and the Low Stress Slurry Consolidation test. Similarly, calculated coefficients of consolidation for the Cyclone Overflow range from about 25 m2/year at very low stresses to over 1000 m2/year at high stresses. The relationship between coefficient of consolidation and effective stress for the Cyclone Overflow is shown on Figure 4.2.
The relationship between tailings void ratio and effective stress is shown for the Whole Tailings and Cyclone Overflow materials on Figures 4.3 and Figure 4.4 respectively. These relationships were developed using calculated void ratios provided by the Slurry Consolidometer tests and the Low Stress Slurry Consolidation tests. The data presented on Figures 4.2 and 4.3 suggests a bilinear relationship between void ratio and effective stress for both materials. At low effective stress levels the steep line is indicative of the large volume change which occurs during the tailings sedimentation and initial consolidation process. The shallower line exhibited for higher stresses is indicative of the consolidation process, whereby smaller volume changes occur under increased loading as the structure of the tailings material becomes more compact. This bilinear relationship is typical for sedimented tailings materials.
The vertical coefficient of permeability of the Whole Tailings is shown as a function of effective stress on Figure 4.5. These relationships were developed using permeability values provided by the Slurry Consolidometer tests, Low Stress Slurry Consolidation tests and Falling Head tests performed on the drained settled samples. As expected, a general trend of decreasing permeability with increasing effective stress (decreasing void ratio) is observed. The relationship presented on Figure 4.5 indicates that the permeability of the Whole Tailings will generally range from approximately 1 x 10-4 cm/sec (representing unconsolidated or fresher tailings near surface) to about 1 x 10-6 cm/sec or less, corresponding to an increase in effective stress and reduction in void ratio (representing more consolidated or deeper tailings within the deposit).
The vertical coefficient of permeability of the Cyclone Overflow is shown as a function of effective stress on Figure 4.6. The relationship presented on Figure 4.6 indicates that the permeability of the Cyclone Overflow will generally range from approximately 5 x 10-5 cm/sec to about 1 x 10-6 cm/sec.

CYCLONE SAND TESTS 5 –
GENERAL 5.1
Compaction, shear strength and permeability tests were carried out on the laboratory manufactured Cyclone Underflow (cyclone sand) sample. The test samples used for shear strength and permeability testing were prepared to target density and moisture content conditions representative of compacted cyclone sand fill material used for embankment construction.
The shear strength and permeability tests were carried out over a large range of confining stresses to examine the influence of a large dam height (and corresponding high confining stress) on the strength and permeability values.
Complete results of the compaction, shear strength and permeability tests are included in Appendix A.
COMPACTION TEST 5.2
The maximum dry density and optimum moisture content of the Cyclone Underflow sample were determined from a Standard Proctor test (ASTM D-698-07 Method A Standard). The optimum moisture content was determined to be 16.7% and the maximum (ultimate) dry density was 1,559 kg/m3. Test samples used for shear strength and permeability testing were prepared to 95% of the maximum dry density.
SHEAR STRENGTH TEST 5.3
Consolidated Undrained triaxial compression tests were carried out on the Cyclone Underflow sample to determine the shear strength of the material over a range of confining stresses. The tests were performed at effective confining stresses of approximately 350 kPa, 700 kPa, 1650 kPa and 2760 kPa.
The effective shear strength of the cyclone sand is defined by the effective friction angle and cohesion. The test results indicate an average effective friction angle of 36 degrees with zero cohesion.
The potential strength characteristics of the cyclone sand over a large stress range has also been examined, including estimation of the shear strength (effective friction angle) at low and very high stresses. The strength of granular materials is typically higher at low stresses due to the dilatant behaviour of the material under shearing, while a lower strength may occur at high stresses due to particle crushing and reduced dilation of the material. The shear strength test results for the Cyclone Underflow have been compared to published information on the strength characteristics of granular materials (rockfill and angular sands) provided by Leps (“Review of Shearing Strength of Rockfill, Journal of the Soil Mechanics and Foundations Division, ASCE, Vol. 96, No. SM4, July 1970). Specifically, a relationship between friction angle and effective stress provided for angular sands has been used for comparison to the Cyclone Underflow test results. This relationship suggests that the effective friction angle of the cyclone sand will be greater than 36 degrees at low confining stresses (approximately 40 degrees for a normal effective stress of 100 kPa), but potentially lower at very high stresses (about 30 degrees for very high effective stresses of about 4000 to 5000 kPa). However, it

is noted that the laboratory test results for the Cyclone Underflow sample suggest that there is no apparent loss of strength at the higher stresses, over the stress range tested. This is an important consideration for stability assessment of large cyclone sand dams where confining stresses can be very high.
PERMEABILITY TEST 5.4
Flexible Wall Permeability tests were carried out at applied confining stresses of approximately 350 kPa, 700 kPa, 1650 kPa and 2760 kPa. The tests were carried out at these confining stresses to investigate the influence of increasing confining stress (and corresponding embankment height) on the permeability of the material.
The permeability values determined for the Cyclone Underflow sample are presented on Figure 5.2, which shows a general trend of reducing permeability with increasing confining stress. This decrease is the result of the increase in material density (decrease in void ratio) and potentially from the generation of finer particles due to particle crushing. However, the results do not appear to indicate a dramatic decrease in permeability at high stresses, which would be indicative of significant particle crushing and changes to the fines content of the material. The particle size distribution of the sample was determined following completion of the permeability test to investigate the potential for increased fines content due to particle crushing. The measured fines content (% passing #200 sieve) of the sample increased by only one percent, from 15% to 16%. This is not enough to suggest any significant particle crushing under the very high confining pressures imposed during the permeability testing.
The relationship presented on Figure 5.2 indicates that the permeability of the Cyclone Underflow will generally range from approximately 2 x 10-3 cm/sec at lower stresses to about 5 x 10-4 cm/sec at higher stresses (approximately 3000 kPa). Extrapolation of these results suggests that the permeability of the Cyclone Underflow will remain greater than 1 x 10-4 cm/sec at very high stresses of about 4000 to 5000 kPa.
