Gauge pressure increment, = MAGP / N_Stage kPa 29 P_INC (use 5 PSI)

Stage duration (consists of 3 equal duration sub-stages) min 15 stage duration (typically 15min, consisting of three 5min substages)

Packer seated in landing ring test

Water drop noted in broken rods either (Y or N)

Drop below top of rods mm NOTE: Fill rods to overflowing prior to test

Test duration min Time taken to drop

Pressure disipation test

Bypass backflow pressure (intantaneous) kPa bypass flow immediately after last test cycle and record instanteous back pressure

Duration to dissipation to zero gauge pressure min Recovery period

(1) If fuild returns via casing during test (indicating bypass /poor seal) , record flow rate during each corresponding test substage. For example: 2min:45secs to fill 22.5L bucket(2) No need to carry out rod leakage tests L2 and L3 if L1 shows no flow (ie. No rod leakage) (not applicable for pneumatic packer)(3) 1 psi = 6.8948 kPa = 0.06895 bar; use kPa if possible(4)

The whole soil was used for these hydrometer tests. As the organic content of the soil was very low, peroxide pretreatment was not carried out. A solid density of 2.65t/m3 was assumed for these hydrometer tests, and is not part of the IANZ endorsement for this report. As per the reporting requirements of NZS4402: 1986: Test 2.1: water content is reported to two significant figures for values below 10%, and to three significant figures for values of 10% or greater. Test 2.8.1: wet sieve & Test 2.8.4: hydrometer, the ‘percentages passing’ and ‘percentages fine than’ are reported to nearest 1%. Please note that the test results relate only to the samples under test. Thank you for the opportunity to carry out this testing. If you have any queries regarding the content of this report, please contact the undersigned at your convenience.

Yours faithfully, Justin Franklin Signatory (Assistant Laboratory Manager) Babbage Geotechnical Laboratory

*These samples were prepared from weakly cemented rock core. The soil was wet up and sieved through a

425µm sieve, with more water added if necessary to obtain the liquid limit. The sample was then dried back to the plastic limit moisture content. As per the reporting requirements of NZS4402: 1986: Test 2.1: water content is reported to two significant figures for values below 10%, and to three significant figures for values of 10% or greater. Test 2.2: liquid limit and test 2.3: plastic limit are reported to the nearest whole number. The whole soil was used for all water content tests (the soils were in a natural state), and for the plastic limit

and liquid limit tests without a diamond beside them. The soil fraction passing a 425µm sieve was used for the plastic limit and liquid limit tests with a diamond (�) beside them. The soil was wet up and dried where required for the plastic limit and liquid limit tests. Please note that the test results relate only to the samples under test.

CONSOLIDATED, UNDRAINED (CU), MULTI-STAGE TRIAXIAL COMPRESSIVE STRENGTH TESTING

Dear Sir,

Re: HACKETT DIVERSION Report Number: 60770#L/CU Triaxial BH08 3.00 – 3.45m

Borehole No: BH08 Sample No: TUBE Depth: 3.00 – 3.45m The following report presents the results of triaxial compressive strength testing of a 54mm diameter undisturbed push-tube soil sample delivered to this laboratory on the 12th of July 2017. The client request was to measure the consolidated, undrained compression of the sample in a triaxial apparatus under known conditions of effective stress, with measurement of porewater pressure. We were instructed to test a single sample at effective pressures of 30kPa, 60kPa, and 120kPa by carrying out a 3-point multi-stage test. Please note that the multi-stage method described below is commonly carried out by soils testing laboratories, but is not part of BS1377:1990: Part 8: Section 7 (in which a number of specimens taken from one soil sample are each tested to failure at different effective pressures). The method described below is therefore a departure from BS1377:1990: Part 8: Section 7. Test standards used were: Water Content: NZS4402: 1986: Test 2.1

Preparation of specimen: BS1377: 1990: Part 8: Section 4

Saturation: BS1377: 1990: Part 8: Section 5

Consolidation: BS1377: 1990: Part 8: Section 6

Consolidated-undrained triaxial compression test with measurement of pore pressure: BS1377: 1990: Part 8: Section 7

Test Procedure The sample was extruded from the push-tube and trimmed to length. The sample was then set up in a triaxial cell & saturation was achieved in distinct stages by 30kPa increments of cell pressure and back pressure, with a differential pressure of 10kPa (cell pressure 10kPa greater than back pressure) in order to maintain a small positive effective stress.

The final saturation stage used a cell pressure of 400kPa and a back pressure of 390kPa. Saturation was then confirmed by increasing the cell pressure to 450kPa, and observing the increase in porewater pressure. A porewater pressure coefficient (B) of 0.99 was achieved, confirming saturation of the sample. The cell pressure was then lowered to 420kPa, and the porewater pressure was allowed to stabilise before the first consolidation cycle was begun. Excess porewater pressure was then dissipated during the first consolidation cycle, resulting in an effective stress of 30kPa. The sample was then compressed at a set rate of 0.010mm per minute (actual rate of 0.009mm per minute) until the deviator stress was close to maximum. Compression was then stopped and the load taken off the sample. Cell pressure was increased to 450kPa and the resulting increased porewater pressure was dissipated in the second consolidation cycle, resulting in an effective pressure of 60kPa acting on the same sample. Once consolidated, the 2nd compression cycle was compressed at a set rate of 0.010mm per minute (actual rate of 0.009mm per minute) until the deviator stress was close to maximum. Compression was again stopped and the load taken off the sample. Cell pressure was increased to 510kPa and the resulting increased porewater pressure was dissipated in the third consolidation cycle, resulting in an effective pressure of 120kPa acting on the same sample. Once consolidated, the 3rd compression cycle was compressed at a set rate of 0.010mm per minute (actual rate of 0.010mm per minute) until complete failure of the sample had occurred. Mohr circle plots for each cycle are presented on page 4 of this report. We leave the determination of the angle of resistance and the cohesion to our clients, but as a guide to this we tabulate each tangent to sets of circles on the graph. This test was carried out in a laboratory in which the temperature is controlled between 18°C and 22°C. Each test result is data obtained at a specific test location. The nature and continuity of subsoil conditions away from the test area could vary from the data recovered during this testing. Thank you for the opportunity to carry out this testing.

CONSOLIDATED, UNDRAINED (CU), MULTI-STAGE TRIAXIAL COMPRESSIVE STRENGTH TESTING

Dear Isabella,

Re: ST MARYS BAY Report Number: 61256#L/CU Triaxial MA01 1.70 – 2.20m

Borehole No: MA01 Sample No: TUBE Depth: 1.70 – 2.20m

The following report presents the results of triaxial compressive strength testing of a core sample delivered to this laboratory on the 13th of February 2018. The client request was to measure the consolidated, undrained compression of the sample in a triaxial apparatus under known conditions of effective stress, with measurement of porewater pressure. We were instructed to test a single sample at effective pressures of 10kPa, 20Pa, and 40kPa by carrying out a 3-point multi-stage test. Based on our experience, however, these pressures were considered far too low to give a reliable test result, so effective stresses of 40kPa, 80kPa and 160kPa were agreed with the client. Please note that the multi-stage method described below is commonly carried out by soils testing laboratories, but is not part of BS1377:1990: Part 8: Section 7 (in which a number of specimens taken from one soil sample are each tested to failure at different effective pressures). The method described below is therefore a departure from BS1377:1990: Part 8: Section 7. Test standards used were: Water Content: NZS4402: 1986: Test 2.1

The final saturation stage used a cell pressure of 400kPa and a back pressure of 390kPa. Saturation was then confirmed by increasing the cell pressure to 430kPa, and observing the increase in porewater pressure. A porewater pressure coefficient (B) of 1.00 was achieved, confirming saturation of the sample. Excess porewater pressure was then dissipated during the first consolidation cycle, resulting in an effective stress of 40kPa. The sample was then compressed at a set rate of 0.015mm per minute (actual rate of 0.015mm per minute) until the stress ratio was close to maximum. Compression was then stopped and the load taken off the sample. Cell pressure was increased to 470kPa and the resulting increased porewater pressure was dissipated in the second consolidation cycle, resulting in an effective pressure of 80kPa acting on the same sample. Once consolidated, the 2nd compression cycle was compressed at a set rate of 0.015mm per minute (actual rate of 0.014mm per minute) until the stress ratio was close to maximum. Compression was again stopped and the load taken off the sample. Cell pressure was increased to 550kPa and the resulting increased porewater pressure was dissipated in the third consolidation cycle, resulting in an effective pressure of 160kPa acting on the same sample. Once consolidated, the 3rd compression cycle was compressed at a set rate of 0.015mm per minute (actual rate of 0.014mm per minute) until complete failure of the sample had occurred. Mohr circle plots for each cycle are presented on page 4 of this report. We leave the determination of the angle of resistance and the cohesion to our clients, but as a guide to this we tabulate each tangent to sets of circles on the graph. This test was carried out in a laboratory in which the temperature is controlled between 18°C and 22°C. Each test result is data obtained at a specific test location.

UNCONSOLIDATED, UNDRAINED, ‘QUICK’ (QU) TRIAXIAL COMPRESSIVE STRENGTH TESTING

Dear Isabella,

Re: ST MARYS BAY Report Number: 61256#L/UU Triaxial The following report presents the results of unconsolidated, undrained, ‘quick’ (QU) triaxial compression testing of a core sample delivered to this laboratory on the 13th of February 2018. Test results are summarised below, with the following pages showing detailed results. The samples were tested in accordance with the following standards:

Water Content: NZS4402:1986:Test 2.1 Determination of the undrained shear strength in triaxial compression without measurement of pore pressure BS1377:1990: Part 7: Section 8 (definitive method): The sample was set up in a triaxial cell with a single covering membrane (having a total thickness of 0.2mm), and the cell was then filled with water. The cell pressure was then raised to the required pressure of 180kPa (as per your instructions) and the axial load applied straight away. The loading machine was set at a rate of compression to induce failure within 5 to 15 minutes. The rate of compression was set at 0.50mm / minute. The load versus strain was measured until failure.
