EXECUTIVE SUMMARY
Queensland Energy & Minerals Pty Ltd (converting to a public company and to be renamed 'QEM Limited') ( QEM ) has engaged Measured Group Pty Ltd ( Measured ) to prepare an Independent Geologist’s Report for the Julia Creek Project situated in north-west Queensland.
The Independent Geologist who has prepared this report is Mr Lyon Barrett, Principal Resource Geologist of Measured Group Pty Ltd. Mr Barrett is the current Competent Person for the Julia Creek vanadium Resource, along with Mr Graham Pope of Measured Group Pty Ltd, who is the current Qualified Evaluator for the Julia Creek Oil Shale Petroleum Resource.
Neither Measured, Mr Barrett or Mr Pope have any material interest in QEM or the Julia Creek Project. Measured is remunerated for this report by way of a professional fee based on a standard schedule of rates, which is not contingent on the outcome of this report.
The target geological horizon for the Julia Creek Project is the Toolebuc Formation, which contains potentially economic quantities of both vanadium and oil from oil shale. The Toolebuc Formation is an early Cretaceous aged (Albian approximately 110 My) sedimentary unit that consists of a lower kerogenous shale (oil shale) and an upper interbedded limestone (coquina) and shale unit.
The vanadium and oil shale resources are hosted by, and co-located within, the Toolebuc Formation. A strong correlation between vanadium and oil grades has been previously established by historical observations and this has been confirmed by analysis of recent drilling results.
At this stage, the vanadium Mineral Resource and oil shale Petroleum Resource stand on their own; as there has been insufficient work completed by QEM to confirm that the vanadium Mineral Resource and oil shale Petroleum Resource can be extracted together. However, QEM is assessing several processing options and technologies to maximise the recovery of both the Mineral and Petroleum Resources.
The Mineral Resource estimate for the Julia Creek Project is summarised in Table 1, while Table 2 summarises the Petroleum Resource estimate. The Mineral Resource is estimated and reported as per the JORC Code, 2012 and the Petroleum Resource is estimated and reported as per the SPE-PRMS, 2011.

Notes:
-
The estimate uses a minimum cut-off oil yield of 40 L/tonne, rounded down to nearest million tonnes.
-
The total resource tonnage reported is rounded to reflect the relative uncertainty in the estimate and component horizons may not sum correctly.
-
There are no 1C or 2C Resources as the current points of observation (drill hole spacing) of the oil shale grade is insufficient to place reliable confidence on both grade and thickness continuity required for 1C or 2C resources.
The Independent Geologist has identified the following issues that may present as potential risks to the Julia Creek Project:
-
Unknown geological structures, such as faults, which have been identified at a regional scale from 2D seismic surveys (Troup et al 2018) but have not yet been identified at a deposit scale. At least one recent drillhole in the project has intersected interpreted faulting, however drillhole spacing is currently insufficient to understand potential fault orientations, and the impact the fault(s) may have on proposed mining operations.
-
Estimates of insitu density and moisture. Data collected thus far has led to an insitu moisture estimate of 6%, which is consistent with observations made by Coxhell and Fehlberg, 2000 for Oil Shales of the Toolebuc Formation and low compared to several other Oil Shale deposits in Queensland. Further work is required to gain a better
v

understanding of the deposit’s moisture for both resource estimation and processing purposes.
-
Environmental and/or social impacts, which have not yet been identified by QEM that may adversely impact on resource recovery or extraction methods.
-
Detailed metallurgical studies will be required to confirm that the vanadium Mineral Resource and oil shale Petroleum Resource can be commercially recovered from the same ore material (i.e. host rock); and to identify the optimum methodology for the recovery of oil and vanadium, in addition to any other potential base metal bi-products (Cu, Mo, Ni and Zn).
Further work, including drilling, sampling and analysis to address items 1 and 2, environmental assessments to address item 3; and further assessment of processing and technology options to address item 4 may mitigate each of these risks.
Further drilling will be required to upgrade the JORC Mineral Resource to Indicated and/or Measured, and the SPE-PRMS Petroleum Resource to 2C and/or 1C.

2.3 Topography, Land Use and Climate
The topography over the Julia Creek Project area is generally flat lying with an average elevation of approximately 145 m above sea level. The highest point within the project area is 154 m above sea level.
The project area consists of flat black soil plains typical of the Eromanga Basin. The land in the region is used primarily for grazing cattle, with agricultural activities being generally reliant upon artesian groundwater bores established during the last hundred years.
Vegetation in the Julia Creek region is typically Mitchell Grass dominated native pasture, with a sparse or absent cover of trees and shrubs as shown in Figure 2-3. Prickly Acacia is common in areas of disturbance around existing road quarries and open bore drains.
The climate is described as semi-arid. It is subject to monsoonal influences from the northwest and easterly influences. Around Julia Creek the mean annual rainfall is about 469 mm, with evaporation exceeding rainfall by a factor of 5. Much of the rainfall (about 80%) falls in the summer months between December and March. Typically, the wettest months are January and February.

3. Regional Geology Setting
3.1 Regional Geology
The Early Cretaceous Toolebuc Formation is the target geological horizon at the Julia Creek Project (Figure 3-1). This stratigraphic unit occurs throughout the Eromanga and Carpentaria Basins in eastern, central and northern Queensland and into portions of the Northern Territory and South Australia.
The Eromanga Basin is a sub-basin of the Great Artesian Basin and consists of several thick sequences of non-marine to marine sedimentary units. The Toolebuc Formation is part of the Wilgunya Subgroup of the Rolling Downs Group of the Eromanga Basin that covers a wide but relatively shallow structural depression in eastern Australia, over an area of 1.5 million km[2] .
Sedimentation in the Eromanga commenced in the early Jurassic period, with the deposition of fluvial sandstones of the Hutton Formation due to down warping of the basement (Exon and Senior, 1976). These non-marine Jurassic sandstones are the main aquifers of the Great Artesian basin. Further fluviatile lacustrine and possibly deltaic sedimentation, continued at the close of the Jurassic. A worldwide marine transgression during the Cretaceous period (Schlanger and

Jenkyns, 1986) was marked in the Eromanga Basin by the deposition of shallow marine and paralic sediments, including the Toolebuc Formation. Following final withdrawal of the sea, lithic sediments were deposited above Toolebuc Formation.

The Toolebuc Formation is an early Cretaceous aged (Albian approximately 110 My) sedimentary unit that consists of a lower kerogenous shale (Oil Shale) and an upper interbedded limestone (coquina) and shale unit (Coxhell and Fehlberg, 2000). The Toolebuc Formation crops out at the margins of the Eromanga and Carpentaria basins or, in the case of the Julia Creek area, where it is draped over an original basement high (the St Elmo Structure) (Figure 3-2). Where the unit crops, it forms low rubbly, topographic highs which have been the source of road building materials.

3.2 Economic Geology
The Toolebuc Formation has been the subject of intermittent exploration by various parties since 1968, originally as a potential target for sedimentary uranium, then as an oil shale and vanadium target and later exclusively as a vanadium target.
Historical exploration activity has confirmed that the continuity of lithological horizons within the Toolebuc Formation is remarkably consistent over wide areas (CR24927 Appendix 1 Pg. 13).
The uppermost unit of the Toolebuc Formation, the St Elmo Coquina, occurs at a minimum depth within the project area of 37.75 m in drillhole 594_712, while the base of the basal Toolebuc Formation unit, the Arrolla Siltstone, is intersected at a maximum depth of 104.42 m in drillhole QEM004.
The Toolebuc Formation at the Julia Creek Project presents as a potential open-cut mining target, with a maximum cumulative strip ratio less than 10 bcm/tonne.
4. Deposit Geology
4.1 Local Geology
Blue-green algae are interpreted to have formed extensive algal mats on an epeiric sea floor during deposition of the Toolebuc Formation. The preservation of dead algal matter can be related to an oxidising-reducing boundary probably situated immediately below the base of the living algal mat layer, the position of which kept pace with the upward growth of the living algal mat.
The kerogen in the Toolebuc Formation are derived from planktonic algae and blue-green benthonic algae (Glikson and Taylor, 1986) with the calcite representing the inorganic component of benthic and planktonic organisms. The detrital component is represented by fine clay and quartz.
The episode of clear water calcareous sedimentation represented by the Toolebuc Formation ended when muddy conditions returned, preventing further growth of the benthonic fauna and leading to widespread deposition of the argillaceous sediments of the Allaru Mudstone (Ramsden, 1983). The Toolebuc is anomalous in a wide range of elements including vanadium, copper, zinc, nickel and molybdenum, fixed from sea water by the living organisms.
Norrish and Patterson, 1976 concluded that the vanadium in Oil Shale at Julia Creek is associated with mixed layered clays and contains approximately 60% of the vanadium present in the fresh Oil Shale. The other 40% occurs within silicates, pyrite and organic compounds.
Mineralogical work completed by Fimiston and others has established that the Oil Shales within the Toolebuc Formation are principally composed of calcite, kerogen, quartz, kaolinite,
Page 9
Julia Creek Project Independent Geologist’s Report, June 2018
==> picture [76 x 43] intentionally omitted <==
smectite and pyrite. Minor minerals identified include mixed layered clays and gypsum. Trace minerals identified include sphalerite, chalcopyrite and galena (Coxhell and Fehlberg, 2000).
More recent work by Troup et al, 2018 used X-ray diffraction ( XRD ) and Hylogger analysis to allow a semi-quantitative assessment of mineral components present in the Toolebuc Formation. The study included samples from GSQ holes throughout the Eromanga and Carpentaria Basins, and included a stratigraphic drillhole called GSQ Julia Creek 1, which is located approximately 45 km to the south-west of the Julia Creek Project area.
Figure 4-1 shows the results for GSQ Julia Creek 1, as presented in Troup et al, 2018. This figure suggests that the mineralogy of the Toolebuc Formation is dominated by Carbonates, with significant Illite, Smectite and Quartz.

The in-situ moisture content of the Julia Creek Oil Shale is estimated to be approximately 6% (Coxhell and Fehlberg, 2000) which is low compared to several other Oil Shale deposits in Queensland. The low moisture content has potential processing benefits when compared to the higher moisture content of Queensland Tertiary Oil Shale deposits.
The vanadium within the Toolebuc Formation is interpreted to have been concentrated by marine organisms, fixing the vanadium from seawater over a long period of time in an anaerobic environment. The vanadium occurs as both organic and inorganic forms suggesting
Page 10
Julia Creek Project Independent Geologist’s Report, June 2018
==> picture [76 x 43] intentionally omitted <==
a unique combination of physical and chemical conditions was necessary for the accumulation of the various vanadium mineral species.
The fossil assemblage and mineralogy of the two main facies of the Toolebuc Formation provide important clues to the depositional environment and possible mechanism for the fixing of the vanadium.
The difference between the upper coquina and lower fine-grained oil shale is related to the amount of oxygen present during deposition, and the possible depth of formation. The lower fine-grained oil shale represents a reducing environment, while the upper laminated coquina represents fluctuating and progressively increased levels of oxygen in the sea suitable for the establishment of specialised low oxygen tolerant large sized benthonic shelly fauna (Ozimic, 1986).
Possible fluctuation in the sea level (and/or in the physio-chemical conditions at the sea floor) sometimes favoured oil shale accumulation, but increasingly favoured formation of the coquina (Ramsden, 1986) (Coxhell and Fehlberg, 2000).
The results of these geological processes are that the vanadium and oil resources found within the Julia Creek Project are hosted by, and co-located within, the Toolebuc Formation. In addition, historical as well as recent drilling and analysis programmes have found a strong correlation between vanadium and oil grade within the target horizons of Toolebuc Formation.
4.2 Stratigraphy
In general, the stratigraphic sequence within the Julia Creek Project area, from the youngest to oldest is as follows:
Surficial Sediments
Around 1 m of brown clay rich to silty soils are intersected at surface across the entire project area.
Allaru Mudstone
The youngest sedimentary units encountered within the project area are the Allaru Mudstones. These are blue to grey massive mudstone units interbedded with occasional 10 cm thick siltstone units. The Allaru Mudstones grade into the underlying St Elmo Coquina.
St Elmo Coquina (Modelled as CQU)
The St Elmo Coquina is composed of interbedded shelly limestone and kerogenous siltstone and claystone bands (Oil Shale) present as thin bands between the limestone units (CR24927). The visible carbonate content of the coquina is over 50%. During correlation and stratigraphic modelling of the recent drilling data within the project area, the St Elmo Coquina has been termed the Coquina Upper unit or CQU.
The Coquina Upper (CQU) is present across the entire Julia Creek Project area, except where it subcrops in EPM 26429. The Coquina Upper averages 4.05 m in thickness in the 10 recent
Page 11
Julia Creek Project Independent Geologist’s Report, June 2018
==> picture [76 x 43] intentionally omitted <==
holes drilled, with the minimum and maximum thicknesses ranging between 2.59 m and 5.02 m respectively.
Willats Crossing Siltstone (Modelled as CQL)
The proportion of Oil Shale bands over limestone increases to over 50% with a gradational transition from the St Elmo Coquina into the underlying Willats Crossing Siltstone. The Willats Crossing Siltstone is comprised of laminated kerogenous siltstone and claystone with up to 50% limestone bands of between 1 mm and 3 cm thick (CR24927) and it is included in the modelled stratigraphic unit called CQL.
Where the underlying Manfred Crossing Siltstone Coquina is present, the proportion of limestone increases towards the basal gradational contact with the Manfred Coquina.
Manfred Coquina (Modelled as CQL)
The Manfred Coquina looks similar to the St Elmo Coquina; however, it is not as laterally persistent as the St Elmo Coquina, and is absent in a number of holes drilled across the project area. Where present, it is characterised by a drop in vanadium content and a spike in Phosphorous content. A distinctive phosphatic band at the base of the Manfred Coquina is an accepted marker band within the Toolebuc Formation (CR24927).
The Manfred Coquina is not always present across the project area and for modelling purposes the two units (Willats Crossing Siltstone and the Manfred Coquina) have been modelled as a single unit called the Coquina Lower or CQL. Due to the gradational contact between the two units and the low level of continuity of the Manfred Coquina, it was deemed to be better from an economic geology perspective to regard these two stratigraphic units as a single unit for the purposes of resource modelling and mining studies.
Combining the two units has the effect of averaging out changes in vanadium content and associated oil yield within the combined unit, lowering the variability and increasing the continuity of vanadium content and oil yield for the combined CQL unit across the deposit.
The CQL is intersected in all holes drilled across the Julia Creek Project area and has an average thickness of 3.14 m in the 10 recent holes drilled by QEM. It reaches a maximum thickness of 5.41 m in drillhole QEM013 and a minimum thickness of 1.29 m in QEM011.
Arrolla Siltstone (Oil Shale) (Modelled as OSU and OSL)
This lowermost oil shale bed consists of finely laminated dark grey pyritic and kerogenous shales. There is normally an increase in clay content in the lower half of the Arrolla Siltstone before a normally sharp contact with the underlying blue grey pyritic mudstones of the Wallumbilla Formation.
The upper portion of the Arrolla Siltstone normally contains the highest oil yield within the succession, with a decrease of oil yield in the lower portion, as clay content increases at the expense of organic matter. For this reason, during correlation and modelling of the Arrolla
Page 12
Julia Creek Project Independent Geologist’s Report, June 2018
==> picture [76 x 43] intentionally omitted <==
Siltstone, the Arrolla Siltstone was sub-divided into two units, namely the Oil Shale Upper (OSU) and the Oil Shale Lower (OSL).
The Oil Shale Upper (OSU) has an average thickness of 1.40 m across the 10 recent holes drilled by QEM. It reaches a maximum thickness of 2.16 m in QEM002 and a minimum thickness of 0.89 m in QEM013. The Oil Shale Lower (OSL) has an average thickness of 1.56 m in the 10 recent holes drilled by QEM. It reaches a maximum thickness of 2.04 m in QEM006 and a minimum thickness of 0.90 m in QEM004.
Wallumbilla Formation
The Wallumbilla Formation is a thick unit (normally +150 m thick) of blue grey pyritic mudstones with minor interbeds of carbonaceous siltstone, fine grained carbonaceous sandstone and concretionary limestone. The uppermost Ranmoor Member of the Wallumbilla Formation is found immediately below the Arrolla Siltstone in the Julia Creek Project area.
5. Exploration History
The earliest drilling within the Julia Creek area was conducted by Australian Aquitaine Petroleum Ltd in the late 1960’s, looking for potential sedimentary uranium targets. Discovery of the extensive oil shales of the Toolebuc Formation led to limited sampling and analysis of the oil shale at the time.
Following this early work, The Oil Shale Corporation ( TOSCO ), CSR Ltd and later CSR Limited explored the area for both open-cut and underground oil shale and vanadium resources between 1970 and 1988.
In the early 1980’s Pacific Coal Pty Ltd held Authority to Prospect ( ATP ) 3144M, the majority of which lies to the north of the current Julia Creek Project area. A small part of ATP 3144M however extended into the current Julia Creek Project, and consequently one hole (OXT003C) was drilled within the current project boundaries. This hole was drilled to the top of the Toolebuc Formation using open-hole methods, then cored, with samples taken across the Toolebuc Formation. The core was analysed for Oil properties, but not vanadium.
Between 1980 and 1981, ESSO undertook drilling of Oil Shales to the south of Julia Creek in order to test the cores for base metal content. ESSO drilled 9 drillholes to the south and west of the current QEM tenements. This work confirmed the base metal anomalism of the Toolebuc Formation in this area. In addition to vanadium grades comparable to those seen to the north (0.35 wt% V2O5 on average) ESSO found anomalous zinc, copper, nickel, uranium and molybdenum.
CRA Exploration Pty Ltd ( CRA ) took up a large tenement position around Julia Creek between 1991 – 1993 and drilled an additional 5 drillholes during that period. CRA compiled a database, completed summary reports on previous oil shale exploration (CR24927) and conducted several technical studies into potential beneficiation options for the oil shale deposit.
Page 13
Julia Creek Project Independent Geologist’s Report, June 2018
==> picture [76 x 43] intentionally omitted <==
At the time CRA concluded that treating Oil Shales for crude oil was not a viable option given that the estimated best case costs of production was AUD42 to AUD48 per barrel, and this was approximately AUD10 to AUD16 above the projected long term oil price at that time.
in the 1980s, CSR Pty Ltd completed 11 drillholes within the area covered by the current QEM tenements. The drilling included open-hole and core drilling, with each drillhole geophysically logged for gamma response using a SIE T450 portable logging unit (CR10671, CR9996).
Oil Shale samples were collected and sent to Australian Laboratory Services ( ALS ) in Brisbane and analysed for:
-
Fischer assay (oil yield);
-
Determination of Specific Gravity of Oil Shale and
-
XRF assay for vanadium, Molybdenum and Uranium. Any sample which assayed over 50 ppm Uranium was analysed for Thorium.
5.1 QEM Drilling (2015)
QEM acquired the tenements for the Julia Creek Project (EPM 25662 and EPM 25681) in early 2015 and completed an exploration programme in August 2015. The programme drilled 996 m in 10 4C (100 mm) core drillholes, with non-core sections drilled using 124 mm PCD bits.
Detailed logging of lithology from chips and core was completed, core loss was documented in the field during logging and sampling of core, all drillholes were geophysically logged and photographs of all 4C core were taken to maintain a complete geological record.
A total of 206 half metre core samples of the Toolebuc Formation were taken from the 10 core holes. All samples were double bagged on site to prevent moisture and volatile losses and were assigned individual sample numbers and accompanied by a sample advice sheet.
Whole cores were delivered to ALS in Townsville, Queensland for weighing, drying, weighing, crushing and splitting prior to assay by ALS in Townsville and Gladstone. ALS maintains a comprehensive sample preparation and assaying procedure to provide quality assurance and quality control ( QAQC ) of assay results. Samples were analysed for the following:
-
Density;
-
Total Moisture;
-
Inherent Moisture;
-
Ash Content;
-
Volatile Matter;
-
ICP AES analysis 33 elements; and
-
Modified Fischer Assay (MFA).
The current Mineral and Petroleum Resource estimates includes all drillholes completed during QEM’s 2015 drilling program in addition to the 6 drillholes completed on the tenements previously by CSR Pty Ltd.

5.1.1 Comparison of QEM 2015 and Historical Drilling
The first 2 holes of the 2015 drilling campaign were located at sites of previously existing drillholes and were drilled with the intention of testing the validity of historical data ( twinned ). Generally, the results of the twinned holes were not an exact match, mostly due to the finer (0.5 m) sampling conducted on the more recent holes. This finer sampling, along with detailed downhole geophysics, has allowed stratigraphic units to defined based on both lithology, oil and vanadium grades.
Figure 5-1 and Figure 5-2 below show a comparison of the twinned QEM 2015 and historic drillholes at the same location. There are clear differences between the data sets, with some of the differences occurring as a result of the coarseness of the samples taken in the historic drillhole.
Although some reasonable vanadium grades have been intersected in the CQU of the QEM 2015 drillholes, it is pod-like and cannot be consistently correlated between drillholes. In addition, the oil yield of the CQU unit is less than 40% and for these reasons, the upper Coquina unit (CQU) was excluded from the resource.
The remaining units in each hole (CQL, OSU and OSL) compare reasonably well overall and provide a reasonable justification for using the historical drillholes to support the current Inferred Mineral Resource classification and estimate.
The twinning of the first two holes of the 2015 drilling campaign has provided further data to confirm and support the interpretation that both the vanadium and oil shale resources are hosted by, and co-located within, the Toolebuc Formation.
In addition, the twinned drillholes provide further support for the interpretation that a strong correlation exists between vanadium and oil grade within the target horizons of the Toolebuc Formation.

6. Resource Estimates
The vanadium Mineral Resource and oil shale Petroleum Resource are hosted by, and colocated within, the Toolebuc Formation and there exists a strong positive correlation between vanadium and oil grade.
At this stage however, there has been insufficient work completed by QEM to confirm that both the vanadium Mineral Resource and oil shale Petroleum Resource can be recovered from the same ore material (i.e. host rock). QEM acknowledges this and is assessing several processing options and technologies to identify the optimum methodology for the recovery of vanadium and oil, in addition to any other potential base metal bi-products (Cu, Mo, Ni and Zn).
As a result, the vanadium Mineral Resource and oil shale Petroleum Resource must stand on their own. Further, it should not be assumed that both resources are currently able to be recovered from the same ore material.
The following summarises the Mineral and Petroleum Resources that are contained within the Julia Creek Project.

6.2 Petroleum Resource Estimate
Within the 1,700 Mt of ore that hosts the vanadium Mineral Resource, a Contingent oil shale Petroleum Resource is estimated at 654 million barrels in-situ (Petroleum Initially in Place) equivalent to a 3C estimate of 589 MMbbls with a 0.9 recovery factor as at 31 March 2018. Table 6-2 below provides a summary of the Petroleum Resource estimate.
There are no 1C or 2C Resources as the current points of observation (drill hole spacing) of the oil shale grade is insufficient to place reliable confidence on both grade and thickness continuity required for 1C or 2C Resources.

6.3 Geology and Geological Interpretation
The main data sources used to support the estimate are the lithological logs, core photographs, down hole geophysical logs and assays for base metals, proximate analysis and oil yield. The correlation of the drillhole data was based on lithological variations, proximate analysis, oil grade and downhole geophysics where available.
Historical data excluded from previous geological models and resource estimates was included back into the current geological models and resource estimates. This was done after the historical drillholes were integrated back into the modelling database and correlated back to the QEM 2015 drillholes. The integration of historical data was further supported by the twinning of two QEM 2015 adjacent to historical drillholes.
Confidence in the sedimentary correlations is considered high as they are based on down holes geophysics, assays and core photographs. A secondary confirmation of the interpretation is the gridded model itself which shows good continuity between data points and this is further supported by geostatistical analysis of drillhole data completed by Measured as part of the resource estimate in 2018.
As a result, the current drilling density and interpreted geological continuity is considered sufficient to support Mineral and Petroleum Resource classifications for orebody thickness, volume, tonnage and grade.
6.4 Vanadium and Oil Grade Correlation
The relationship between vanadium and organic matter was noted by Riley & Saxby (1986) for samples from the Toolebuc Formation over most of the Eromanga Basin, with a strong positive relationship between organic carbon and vanadium and suggested a common source for both the vanadium and the organic matter.
The twinning of the first two holes of the QEM 2015 drilling campaign provided further data to confirm and support the interpretation that both the vanadium and oil shale resources are hosted by, and co-located within, the Toolebuc Formation.
In addition, the twinned drillholes provide further support for the interpretation that a strong correlation exists between vanadium and oil grade. Plots of vanadium and oil grade were
Page 20
Julia Creek Project Independent Geologist’s Report, June 2018
==> picture [76 x 43] intentionally omitted <==
developed for the composited data used in the estimation of oil grade (wt% dry) and vanadium (ppm) (Figure 6-1).
There is a clear relationship between vanadium content and oil grade for each unit within the Toolebuc Formation. The relationship between increasing vanadium and oil grade is more linear for the CQU and CQL units in both QEM and legacy drillholes, while there is more scatter for the OSU and OSL units.
It is noted that the relationship between vanadium content and oil grade for the historical data is offset. The reason for this offset in the historical data for the CQL (relative to the QEM data) is not apparent and will require further investigation.

6.5 Sampling and Sub-sampling Techniques
All QEM core samples were double bagged on site and transported to the laboratory for sample preparation and analysis. Whole cores were delivered to the ALS in Townsville, Queensland for weighing, drying, weighing, crushing and splitting prior to assay by ALS in Townsville and Gladstone.
All samples were prepared using a coarse crush and fine crush. The coarse crush size was - 6mm for 70% of the sample and samples were riffle split into 5 kg portions. One 5 kg portion was stored and the other 5 kg portion was subjected to fine crush. Fine crush was - 2mm for 70% of the sample. The fine crushed 5 kg portion was split into 2.5 kg portions – one for proximate analysis and the other for ICP-AES analysis. No sub-sampling of the core was carried out.
Page 21
Julia Creek Project Independent Geologist’s Report, June 2018
==> picture [76 x 43] intentionally omitted <==
The proximate analysis was completed at ALS Gladstone and the ICP-AES was completed at ALS Townsville. Following proximate analysis, Gladstone used the remaining samples and combined them by length density weighting into sedimentary units as instructed, for Modified Fischer Analysis ( MFA ). ALS maintains a comprehensive sample preparation and assaying procedure to provide quality assurance and quality control ( QAQC ) of assay results.
In each case of the CSR Ltd boreholes the entire core was collected for assay and sent to ALS in Brisbane. The entire core sample was:
-
crushed in a 150 mm jaw crusher set at a nominal 50 mm opening;
-
subsampled by riffling;
-
air dried at 50 degrees centigrade;
-
reduced to minus 2 mm by further crushing in a 50 mm jaw crusher set at a nominal 6 mm opening;
-
riffled down further to about 500 gm sub-sample;
-
homogenised, rolled and dip samples to approximately 100 gm for Fischer Analysis; and
-
the remainder of each sample was stored as a standard sample.
Check assays were carried out by Tosco Laboratories in the USA as well as ACIRL in Rockhampton. All three laboratories used the Modified Fischer Retort Method as outlined in Report R.1. 4477 of the United States Bureau of Mines.
The current Mineral and Petroleum Resource estimates includes all drillholes completed during QEM’s 2015 drilling programme in addition to the 6 drillholes completed on the tenements previously by CSR Pty Ltd.
6.6 Drilling Techniques
QEM’s 2015 drilling programme involved the drilling of 10 drillholes. The drillholes varied in depth from 72 m (QEM002) to 120 m (QEM004). The drilling was completed by rotary core drilling, using 4C (100mm) core and the drill diameter for the chipped section of the hole was 124 mm where PCD bit was used for chipping.
Historically, CSR Ltd drilled 6 drillholes within the area of EPM 25662, and 5 drillholes within EPM26429. Each drillhole was drilled with open hole methods through the Allaru Mudstone at 115 mm diameter. A 65 mm core was then obtained for the remainder of the hole through the Toolebuc Formation and into the Ranmoor shales. Oil shale samples were analysed via a Modified Fischer assay to determine oil yield and specific gravity of oil shale. XRF analysis for vanadium, molybdenum, uranium and thorium was completed for 4 of the drillholes within EPM25662. Additional CSR drillholes were drilled outside of the current tenements, and have been used for geological modelling.
Pacific Coal Pty Ltd drilled one drillhole (OXT003C) within the Julia Creek Project area, and two others (OXT002C and OXT005C) to the north in 1981. These holes were wireline logged

for Gamma as a minimum, but also density and resistivity in some cases. All three drillholes have been used to build the structure model (i.e. supporting stratigraphic unit thickness and RL).
A total of 12 partly cored drillholes were drilled to the north-west and west of the current Julia Creek Project area – all of which intersected the Toolebuc Formation. Vanadium was not analysed in these drillholes, rather Oil Shale related properties. The holes were drilled using open hole methods to the top of the Toolebuc Formation using water injection or air circulation and then cored through the Toolebuc Formation.
6.7 Criteria Used for Resource Classification
Resource classification for Mineral and Petroleum Resources is based on an assessment of the variability of critical variables (vanadium grade, oil grade and sedimentary unit thickness) through statistical analysis, geostatistical analysis and by an assessment of the degree of geological complexity (general dip and structure).
The presence of assay results for vanadium was set as the minimum requirement for a Point of Observation for the estimation of both Mineral Resources and Petroleum Resources.
Insufficient data on the critical variable (vanadium) exists for any meaningful geostatistical study to be conducted and contours of modelled vanadium grades were examined to investigate the variability of this parameter.
The relationship between vanadium grade and oil yield was also examined, and a correlation was found to exist between high vanadium and high oil yield (see Section 6.4). Semivariograms of oil yield and stratigraphic unit thickness were investigated and found to have a range more than 10,000 m in all cases.
Points of Observation for Mineral Resources
The minimum spacing between points of observation was set to 4000 m for the Inferred Mineral Resource category. No attempt was made to classify the resource as an Indicated or Measured Mineral Resource at this stage of the project.
Further acquisition of data (such as infill drilling) will be required to achieve an increased confidence in geological continuity and support an upgraded classification of the vanadium Mineral Resource.
Drillholes intersecting the Toolebuc Formation, with valid oil yield data exist beyond the last line of points of observation. These have been used as supportive data for:
-
structure continuity, as they provide accurate information related to the unit’s thickness; and
-
for grade continuity, based on the relationship between oil yield and vanadium content (see Section 6.4).
Page 23
Julia Creek Project Independent Geologist’s Report, June 2018
==> picture [76 x 43] intentionally omitted <==
Based on these supportive data, the Mineral Resource is classified as 100% Inferred Mineral Resource, of which 0% is extrapolated.
Further information relating to JORC Code, 2012 Mineral Resource estimate is contained within Appendix A.
Points of Observation for Petroleum Resources
Minimum spacing between points of observation was set to 4000 m for the 3C category. No attempt was made to classify the resource at 1C or 2C category at this stage of the project.
Further acquisition of data (such as infill drilling) will be required to achieve an increased confidence in geological continuity and support an upgraded classification of the Oil Shale Petroleum Resource.
Drillholes intersecting the Toolebuc Formation, with valid oil yield data exist beyond the last line of points of observation. These have been used as supportive data for:
-
structure continuity, as they provide accurate information related to the unit’s thickness; and
-
for grade continuity, based on the relationship between oil yield and vanadium content (see Section 6.4).
Based on these supportive data, the Petroleum Resource is classified as 100% 3C, of which 0% is extrapolated. The Petroleum Resource is unrisked.
Figure 6-2 shows the distribution of points of observation and supportive data for the Mineral Resource and Petroleum Resource estimates and the Resource Limits for the Julia Creek Project.
Further information relating to the SPE-PRMS, 2011 Petroleum Resource estimate is contained within Appendix B.
6.8 Sample Analysis Method
All samples taken by QEM in 2015 were analysed according to Australian Standard for proximate analysis to determine Free Moisture %ar, Total Moisture %ar, Inherent Moisture %ad, Ash %ad, Volatile Matter %ad and Fixed Carbon %ad. Relative Density %ad was also determined for each sample.
Oil grade has been determined by modified Fischer Assay (ASTM D3940-90) on 73 core samples representing approximately 244.9 m metres of cored material.
Inductively coupled plasma atomic emission spectroscopy (ICP-AES) has also been conducted on all samples used in the estimate to determine 33 mineral elements including vanadium (ppm).

6.9 Estimation Methodology
A geological model was created for the Julia Creek Project, using grid modelling techniques and ABB’s Minescape software (V5.12).
The FEM (Finite Element Method) interpolator was used for surface elevation, thickness and trend. FEM is a proprietary algorithm that honours individual data points and interpolates between data points. Drillholes within and outside of project boundaries were used for modelling, in order to ensure model continuity across the project area.
The Inverse distance squared interpolator was used for modelling of vanadium and a linear interpolation was used for oil grade estimation. Grid cell sizes of 20 m for the topographic model, 40 m for the structural model and 40 m for the quality model were used. There is no modelling of selective mining units, rather modelling has focussed on stratigraphic units.
Visual validation of all model grids was completed to ensure extreme or outlier values have not influenced any of the grids and estimates. The entire deposit is considered a single domain for each sedimentary unit in terms of stratigraphic unit thickness and grade.
6.10 Cut-off Grade
No minimum stratigraphic thickness cut off was used for estimating resources, and the cumulative thickness of the 3 stratigraphic units which make up the orebody is greater than 4 m throughout the deposit.
A minimum oil yield of 40 l/tonne was used as an oil grade cut-off, and was used to define the CQL, OSU and OSL units. The minimum oil yield effectively excludes the entire CQU unit from the resource but no portion of any of the other three sedimentary units are excluded by applying this cut-off.
No cut-off grade for vanadium was used, however the grade of samples within the modelled resource units rarely drops below a grade of 0.2%.
6.11 Mining and Metallurgical Methods and Parameters
Open-cut mining methods are envisaged for the extraction of the Mineral and/or Petroleum Resources contained within the Julia Creek Project.
Based on an evaluation of the geology and a review of historical work completed to date, a 10 bcm/tonne stripping ratio was identified as a reasonable economic cut-off for resource estimates, albeit preliminary. No portion of the Julia Creek Project area has a modelled strip ratio of more than 10 bcm/tonne, and therefore no areas have been excluded from the resource on this basis.
In 2017 CORE Metallurgy Pty Ltd ( CORE ) investigated and reported on the beneficiation of vanadium only (exclusive of kerogen) from core samples obtained by QEM. Several traditional beneficiation and leaching processes were investigated on two core samples collected in the 2015 drilling campaign (drillholes QEM001 and QEM002). The results of that testwork
Page 26
Julia Creek Project Independent Geologist’s Report, June 2018
==> picture [76 x 43] intentionally omitted <==
confirmed historical reports that the ore consumes high quantities of leachant (acid) due to the presence of gangue minerals (mostly calcite). CORE recommended in their report that "Further vanadium leaching testwork should focus on retorted or ashed material, and could include alternative lixiviants such as hydrochloric acid with regeneration / recycling of acid, or alkaline leaching.” (CORE 2017)
No recent metallurgical studies have been conducted on recovery efficiencies and costs associated with treatment and recovery of both the vanadium Mineral Resource and the oil shale Petroleum Resources. However, QEM is assessing several processing options and technologies to maximise the recovery of both the Mineral and Petroleum Resources, in addition to any other potential base metal biproducts (Cu, Mo, Ni and Zn).
Previously published work by CSR (CR24927) in 1973 indicated that hydrothermal leaching of Oil Shales at 340[o] C recovered about 12% of the vanadium. Hydrothermal leaching at 300[o ] C with additives sodium bicarbonate and sodium carbonate in concentrations equivalent to 5 lbs Na2O per lb V2O5 showed extraction efficiencies up to 90%.
CRA Exploration Pty Ltd took up a large tenement position around Julia Creek during 19911993 and drilled an additional 5 drillholes during that period. CRA compiled a database, completed summary reports on previous oil shale exploration (CR24927) and conducted several technical studies into potential beneficiation options for the oil shale deposit.
At the time CRA concluded that treating Oil Shales for crude oil was not a viable option given that the estimated best-case costs of production was AUD42 to AUD48 per barrel, and this was approximately AUD10 to AUD16 above the projected long-term oil price at that time.
7. Neighbouring Projects
The Julia Creek Project is bordered to the north by EPM 26410 and MLA 100162 (Multicom Resources) and EPMA 26753 (Jorge Resources), to the west and south by EPM 19854 (Quartermain Mining Resources) and to the south by EPMA 26759 (Jorge Resources). In addition, Intermin Resources Limited’s (ASX code IRC, IRCOA) Richmond Vanadium Project is located 10 km north and 45 km north-east of the Julia Creek Project
MLA 100162 is at an advanced stage in its evaluation and an Initial Advice Statement ( IAS ) is available to the public on the Queensland Government Department of Environment and Heritage Protection website.

EPM 26410 is located immediately north of QEM’s EPM 26429, whilst MLA 100162 overlays EPM 26410 but excludes the area south of the Flinders Highway.
Page 27
Julia Creek Project Independent Geologist’s Report, June 2018
==> picture [76 x 43] intentionally omitted <==
A Vanadium Mineral Resource Estimate is described in the St Elmo Vanadium Project Initial Advice Statement ( IAS ) of 546 Mt, consisting of a 15 Mt Measured, 219 Mt Indicated and 313 Mt Inferred Mineral Resource. The resource is contained within fresh and oxidised zones of coquina and oil shale.
Due to commercial sensitivity, Multicom has not included the full geological report (or JORC Table 1) in the IAS, however it does state that the resource is a compliant with the JORC Code, 2012 and was estimated by Resolve Geological, as at March 2017.
The very low strip ratios stated (between surface and 2/1, which is assumed to be 2:1 bcm/tonne) and the presence of oxidised zones suggest that the resource is centred around the subcrop zone of the St Elmo basement high. The same subcrop zone is observed in the Julia Creek Project tenement EPM 26429, indicating that the QEM orebody is a downdip continuation of the same orebody.

7.2 Richmond Vanadium Project (Intermin Resources Pty Ltd)
In March 2018 Intermin Resources Limited announced updated Mineral Resource Estimates for the tenements that make up their Richmond Vanadium Project. The project consists of four separate orebodies, mostly at shallow depths and targeting the vanadium enriched oxide zones.
The Burwood and Manfred orebodies follow a strike parallel to the St Elmo structure, and appear to be the northern extension of the orebody contained in the St Elmo Project (Multicon’s St Elmo Project MLA 100162). The Rothbury and Lilyvale orebodies are located more than 50 km east of the Manfred and Burwood orebodies, and are within the Toolebuc Formation, closer to the eastern basin margin.
The Lilyvale mineralisation is shallow, starting at 5 m from the surface, and occurs in an oxidised limestone/shale unit (likely to be a correlative of the CQU and CQL Coquina units at Julia Creek) and a fine-grained carbonate – clay – Oil Shale unit (likely to be a correlative of the OSU and OSL units at the Julia Creek Project).
The V2O5 grade is significantly higher at Lilyvale than at Julia Creek (0.59% at Lilyvale compared to 0.34% at Julia Creek Project) which is as expected in the oxidised zone, where the oil was leached out and metals enriched.
The total resources reported for the Richmond Project are 2,579 Mt of Inferred Mineral Resource , grading at 0.32% V2O5 at a cut-off of 0.29% V2O5 (per JORC Code, 2102).

8. Planned Exploration
Measured Group understands that QEM intends to conduct an infill drilling programme to provide additional information required to increase geological confidence and provide a basis for QEM to complete feasibility studies.
The drilling programme will be targeted to initially halve the current average distance between points of observation to 2000 m. All drillholes will be cored to acquire samples to analyse for all required minerals (vanadium and Oil Shale).
Given the large amount of supportive data that currently exists (i.e. drillhole intercepts without vanadium assays) and the long ranges currently observed in Variography (for thickness and oil yield) the objective of drilling at this reduced spacing is to convert part of the current Inferred Mineral Resource to Indicated or Measured.
The recent acquisition of EPM 26429, means that the project now has access to sub-cropping Toolebuc Formation and a logical location for a boxcut to establish a lower ratio mining area. Furthermore, it has been observed in nearby projects that vanadium enrichment has occurred in the oxide zones, where the oil was leached out.
Surface mapping and Line of Oxidation (LOX) drilling programmes in the subcrop/outcrop areas are planned to determine a more reliable model of the interface between the mineralised zone and base of weathering. This will also help in identifying any changes in mineralogy as a result of oxidation that occurs above the base of weathering.
The topography surface currently used in the geological model was acquired from SRTM data and displays a consistent offset of 4 m when compared at the surveyed location of drillhole collars. Although this is considered acceptable for an Inferred Mineral Resource, a detailed topography survey is required to allow a more reliable geology model and support future mine planning and feasibility studies. A reliable topography (dataset) will be a pre-requisite for upgrading any future Mineral Resource to a Mineral Reserve (per JORC Code, 2012).
Metallurgical testing is required to investigate costs and recovery factors associated with the recovery of oil, vanadium and any other potential base metal bi-products (such as Cu, Mo, Ni and Zn). Additional testing is planned for future drilling programmes.
Table 8-1 provides a breakdown of the $2.76M Exploration and Studies Budget proposed by QEM for the 2018-2020 period. The budget provides for expenditure to complete works to resolve the issues identified in this section; and appears satisfactory to complete Engineering and Pre-feasibility Studies, Environmental Impact Statement work programmes and other critical compliance related activities.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
Sampling and testing conducted by QEM during the 2015 drilling campaign is described below: Testing took place on the Toolebuc Formation which is the target formation. Cored intersections of the target formation were sampled in 0.5 m sections except where samples were terminated against sharp contacts between sedimentary units. All samples were double bagged on site. Samples were assigned individual sample numbers and accompanied by a sample advice sheet. Half cores were delivered to ALS Coal Division laboratory in Townsville Queensland for weighing, crushing, splitting and testing. Sampling was extensive, with standard tests for all samples including: Total Moisture; Inherent Moisture; Ash Content; Volatile Matter; ICP-AES analysis. ICPAES analysis included a suite of 33 elements, the important ones from the projects prospective being Ca, Cu, Mo and V. Combined samples selected following the above assays: Modified Fischer Assay Industry standard coring (4C) and sampling methods have been used. Sample representivity was ensured by careful observation of the core by a trained geologist during samplinginorderto ensure that samples |

| do not cross unit boundaries and by recording and tracking core recoveries. Sampling and testing of the Oxtown Downs drillholes; OXT002C, OXT003C and OXT005C was conducted in 1981 by Pacific Coal Pty Ltd is described below: In general, all of most of the Toolebuc Formation was sampled as well as the top two meters of the Wallumbilla Formation. Samples of the Allaru Mudstone were also taken in the OXT005C drillhole. All retrieved core was sampled (whole core) on site and packed into polythene bags. Sample divisions were based on lithological variations. Maximum sample length was limited to two meters. Samples from OXT002C and OXT003C were send to ACIRL Rockhampton to be Fischer assayed, while samples from OXT005C were sent to ACIRL at Dinmore. Sampling preparation and analysis carried out by CSR Ltd is described below: Where possible cores were sampled at regular two-metre intervals with sample lengths shorted locally to coincide with lithological contacts. Whole core samples were placed in polythene bags and sent to ALS in Brisbane, where the entire core sample crushed and processed. Left over sample not used in the Fischer Analysis was stored as a standard sample for control purposes. Check assays were carried out by Tosco Laboratories in the USA as well as ACIRL in Rockhampton. All three laboratories used the Modified Fischer Retort Method as outlined in Report R.1. 4477 of the United States Bureau of Mines. |

The most recent drilling programme involved the drilling of 10 drillholes across the tenements. These varied in depth from 72 m (drillhole QEM002) to the deepest hole at 120 m (QEM004), drilled during August 2015. |

| etc). | The drilling was completed by rotary core drilling, using 4C (100mm) core. The drill diameter for the chipped section of the hole was 124 mm where PCD bit was used for chipping. Drilling of the Oxton Downs holes commenced on 28thOctober 1981 and was completed on 18th November the same year. The holes were drilled open to the top of the Toolebuc Formation using water injection or air circulation methods and then cored through the Toolebuc Formation. The weathered section of the Allaru Mudstone was cased off with 125mm diameter PVC. A total of 17 partly cored holes were drilled, all of which intersected the Toolebuc Formation. Prior to this drilling, CSR Ltd drilled 6 holes within the confines of the current extent of EPM 25662, and 5 drillholes within EPM26429. Each borehole was drilled open through the Allaru Mudstone at 115mm diameter. A 65mm core was then obtained for the remainder of the hole through the Toolebuc Formation and into the Ranmoor shales. |

| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
Core loss has been documented in the field during logging and sampling of core. Calculations have been performed to accumulate total core loss over the sampled interval. The core recovery from the entire Julia Creek Project is >90%. Detailed records have been kept of core recoveries which have allowed for analysis of the influence of core recovery on quality during resource estimation. |
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. The total length and percentage of the relevant intersections logged. |
Detailed logging of chips and core was conducted. Chips and core photographs were taken as well. All cores were geologically logged, marked and photographed. Final drill logs include information on detailed lithological logging of the drill core, geophysical logging, core recoveries, quality and the initial interpretation in terms of stratigraphy. All drillhole logs were corrected to down hole geophysics. |

Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. |
No sub-sampling of the core has been carried out. All QEM core samples were double bagged on site and transported to the laboratory for testing. The lab, ALS, complies with Australian Standards for sample preparation and sub-sampling. All samples were subjected to a coarse crush and fine crush. The coarse crush size was -6mm for 70% of the sample. Samples were riffle split into 5 kg portions. One 5 kg portion was stored and the other 5 kg portion was subjected to fine crush. Fine crush was -2mm for 70% of the sample. The fine crushed 5 kg portion was split into 2.5 kg portions - one for the proximate analysis and the other for ICP-AES analysis. The proximate analysis was done at ALS Gladstone division and ICP-AES done at Townsville division. Following proximate analysis, Gladstone used remaining sample, combined by length density weighting into sedimentary units as instructed by QEM contractors, for Modified Fischer Analysis (MFA). In each case of the CSR Ltd boreholes the entire core was collected for assay and sent to ALS in Brisbane. The entire core sample was: crushed in a 150 mm jaw crusher set at a nominal 50 mm opening subsampled by riffling air dried at 50 degrees centigrade reduced to minus 2 mm by further crushing in a 50 mm jaw crusher set at a nominal 6 mm opening riffled down further to about 500 gm sub-sample homogenised, rolled and dip samples to approximately 100 gm for Fischer Analysis |

| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
ALS Minerals and Geochemistry Laboratory (ALS Townsville and ALS Gladstone laboratory in Queensland) adheres to internal QAQC and inter-laboratory QAQC checks. All determinations performed adhere to the American Society for Testing and Materials (ASTM) guidelines. ALS complies with ASTM standards for all ore quality tests and is certified by the National Association of Testing Authorities Australia (NATA). ALS laboratories are regularly benchmarked by external auditors against the highest professional laboratory standard – ISO 17025. Accreditation to this standard provides assurance that the laboratory systems are robust and maintained at world-class level. Weatherford Wireline Services performed all downhole geophysical logging. Down hole sample spacing for all tools is 1 cm. Density, gamma, calliper, sonic, verticality and resistivity tools were run. Weatherford wire line services is ISO9001 certified and uses numerous Quality Control procedures, from the set-up and calibration of down hole tools to the final delivery of client data. |
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. |
Verification of assay data was performed by means histograms of sedimentary unit composites constructed to check for outliers. No outliers were found. Once imported into MineScape gridded assay values were visually inspected to check for anomalies. The first two 2015 holes drilled (QEM001 and QEM002) were drilled adjacent to old CSR holes (597.8_709.9 and 596_710). Intersection depths for the top of the Coquina agreed with CSR holes to within 1 m. Although,total thickness of the Toolebuc did differ bybetween 10% |

| and 20%, when the CQU unit is discarded (as it is from the resource) the remaining thickness of the Toolebuc Formation matched the historical holes to within an acceptable margin. All results received from ALS were supplied in elemental format (ppm). As the vanadium price is quoted according to the concentration of the oxide (V2O5), assay data in V ppm was converted to wt% oxide prior to importing into MineScape. The ppm value was firstly divided by 10 000 to convert to wt%. The wt% of the element (V) was then multiplied by 1.7852 to convert to wt%V2O5. |

|---|---|---|
| Location of data points |
Accuracy and quality of surveys used to locate drillholes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
A differential GPS survey of all collars has been conducted upon completion of drilling by registered surveyors, M.H.Lodewyk Pty Ltd. The grid system used is MGA 94 Zone 54. Old drillhole coordinates are in AMG 84/66 Zone 54 and were transformed into MGA 94 Zone 54 prior to importing into MineScape. The topography surface was generated from SRTM Worldwide Elevation Data (3-arc-second or 90 m resolution). Although the absolute resolution of the elevation data is low, it is internally consistent, i.e. the degree of departure of elevation from the true elevation within a given area is consistent throughout the data set. This provides an opportunity to calibrate the SRTM data with the more accurate surveyed collar positions. It was noted that the SRTM data shows a consistent +4 m bias compared to the elevation of the surveyed collar position at the 10 drillhole locations. To correct for this bias the SRTM xyz data was adjusted by subtracting 4 m from each SRTM data point z coordinate. |
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. |
Data spacing is sufficient to establish continuity in both thickness and quality. Sedimentary unit composites of quality have been used in resource estimation. |

| Whether sample compositing has been applied. | ||
|---|---|---|
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Composites used, therefore orientation of sampling not seen to introduce bias as all drilling is sub-vertical and sediments gently dipping. No bias introduced by orientation of drillholes – MineScape, the 3D modelling software used, takes into account the orientation of the layers in relation to the drilling and determines both true and vertical thickness. |
| Sample security |
The measures taken to ensure sample security. | Sample security was ensured under a chain of custody between QEM contract personnel on site and the ALS lab. |
| Audits or reviews |
The results of any audits or reviews of sampling techniques and data. |
No audits of sampling etc. done however comprehensive set of internal company procedures exist and are adhered to by all QEM contract staff. |
Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | JORC Code explanation | Commentary |

| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. | In 1981 CSR Ltd. drilled a series of exploration holes within the current QEM’s Julia Creek project for the measurement of oil yield and vanadium content from the Toolebuc Formation. The drillholes reached a total depth of between 65 m and 101.36 m, intersecting the Toolebuc Formation between 16.8 m to 84.39 m. |
|---|---|---|
| Geology | Deposit type, geological setting and style of mineralisation. | The Julia Creek Oil Shale deposit was deposited as the basal layer to the Early Cretaceous Toolebuc Formation. The Oil Shale is described as consisting of fine grained carbonate-clay-Oil Shale (Coxhell and Fehlberg, 2000). The top part of the Toolebuc Formation consists of coarse limestone rich clay-oil-shale termed as the Coquina Limestone (Coxhell and Fehlberg, 2000). The Toolebuc Formation forms part of the greater Eromanga Basin, which covers a wide structural depression within central and northern Queensland. Up to 100m of Late Cretaceous age Allaru mudstones overlie the Coquina Limestone (also part of the Eromanga Basin). Weathered mudstones and topsoil overly the fresh Allaru mudstones. |
| Drillhole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drillholes: o easting and northing of the drillhole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drillhole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |

| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated. |
Sample results have been composited over full sedimentary unit thickness using length and density weighting. No metal equivalents have been used. |
|---|---|---|
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drillhole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
The orientation of drilling/sampling (sub-vertical) is not seen to introduce any bias as all drilling is vertical and sediments mostly gently dipping. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drillhole collar locations and appropriate sectional views. |
See Appendices |
| Balanced reporting |
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
All exploration results pertaining to holes drilled during 2015 drilling at Julia Creek Project have been fully documented in this report. Holes drilled previously have been reported in QDEX reports by CSR Ltd. And others. |
| Other substantive exploration data |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
Lithological logging, sampling and assay testing of the Toolebuc Formation, down hole geophysics where available in historic holes and for all new (2015) holes. |

Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
Additional detailed exploration work inclusive of additional drilling will be required to increase confidence in local estimates of tonnes and grade. Ground geophysical surveys required to assess potential faulting. |

Section 3 Estimation and Reporting of Mineral Resources
(Criteria listed in section 1, and where relevant in section 2, also apply to this section.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Database integrity |
Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. Data validation procedures used. |
All data relevant to previous resource estimates was provided to Measured by QEM. This data was provided in the form of Minescape tables and design files, plus a series of Excel spreadsheets, las files etc. Measured Group have created a GDB database and loaded all relevant data into that database. GDB is a proprietary database platform, provided by ABB. It includes a standard set of data validation checks which are tested during the data loading process. Any data which fails the validation checks cannot be loaded into the database. In addition to data used for previous resource estimates, a large amount of historical and regional data was also capture, loaded to the database, and validated in a similar manner. |
Page 46
Julia Creek Project
Independent Geologist’s Report, June 2018
==> picture [76 x 43] intentionally omitted <==
| Having a reliable database as the central repository for all relevant drillhole data is a much more efficient and secure way to store and access relevant data. |
||
|---|---|---|
| Site visits | Comment on any site visits undertaken by the Competent Person and the outcome of those visits. If no site visits have been undertaken indicate why this is the case. |
To date, no site visits have been conducted by the competent person, however a visit is planned to coincide with the start of the next planned drilling programme. The competent person is however very familiar with the regional geology, having worked on many projects throughout North and Central Queensland over the previous 20 years. |
| Geological interpretation |
Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral deposit. Nature of the data used and of any assumptions made. The effect, if any, of alternative interpretations on Mineral Resource estimation. The use of geology in guiding and controlling Mineral Resource estimation. The factors affecting continuity both of grade and geology. |
The main data sources used in the estimate are the lithological logs/core photographs, down hole geophysical logging, and assays for both base metals, proximate analysis and oil yield. Confidence in the sedimentary correlations is considered high as they are based on down holes geophysics, assays and core photographs. A secondary confirmation of the interpretation is the gridded model itself which shows good continuity between data points. Therefore, the current drilling density is considered sufficient for seam thickness and quality and has been confirmed with geostatistics for the resource classification assigned i.e. Inferred. Closer spaced drilling will be required to upgrade the degree of resource confidence. Historical data previously excluded from the model has been included in this estimate. Historical data was identified as adequate after correlations were made to the 2015 holes. Correlations were based on lithological variations, proximate analysis, oil grade and downhole geophysics where available. |
| Dimensions | The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource. |
See figures in appendices. Target for the Resource (Toolebuc Formation) extends over a strike length or around 11 km in the NNE direction across theproject area. |

| Across strike width is around 12 km at its widest point. Target horizon (Toolebuc) found at depths of between 46 m and 104 m below surface. |
||
|---|---|---|
| Estimation and modelling techniques |
The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. The assumptions made regarding recovery of by-products. Estimation of deleterious elements or other non-grade variables of economic significance (eg sulphur for acid mine drainage characterisation). In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed. Any assumptions behind modelling of selective mining units. Any assumptions about correlation between variables. Description of how the geological interpretation was used to control the resource estimates. Discussion of basis for using or not using grade cutting or capping. The process of validation, the checking process used, the comparison of model data to drillhole data, and use of reconciliation data if available. |
The FEM interpolator used for surface elevation, thickness and trend. The Inverse distance squared interpolator used for quality throughout. Linear interpolation was used for oil grade parameter grid estimation. Based on experience, the FEM interpolator is considered to be the most appropriate for structure and inverse distance the most appropriate for quality. Grid cell sizes of 20 m for the topographic model, 40 m for the structural model and 40 m for the quality model were used. No assumptions made regarding correlation or selective mining units. Visual validation of all model grids performed to ensure no extreme values have not influenced any of the grids. The entire deposit is considered a single domain for each sedimentary unit in terms of unit thickness and grade. The previous resource estimate did not include any of the historical holes in the area, therefore the current estimate has included an extra 31 holes. The previous estimate has stated that historical holes were excluded due to inconsistencies between thicknesses of units picked from recent drilling and those picked in historic drilling. These perceived inconsistencies have been resolved through detailed examination of historical logs from company reports, and subsequent re-correlation of units in historical drillholes. |
| Moisture | Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content. |
All tonnages have been adjusted to insitu density. 6% insitu moisture has been assumed, based on values for total moisture obtained from recent drilling, and documentation from historical reports (Coxhell and Fehlberg, 2000). |

| Cut-off parameters |
The basis of the adopted cut-off grade(s) or quality parameters applied. |
The Mineral Resources contained in this report are confined within the concession boundaries. No minimum thickness cut off was used for calculating resources. A minimum oil yield of 40 L/tonne was used as an oil grade cut-off. This effectively excludes the entire CQU from the resource but no portion of any of the other three sedimentary units are excluded by applying this cut-off. |
|---|---|---|
| Mining factors or assumptions |
Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made. |
Open-cut mining methods are envisaged for the extraction of the Mineral and/or Petroleum Resources contained within the Julia Creek Project. Based on an evaluation of the geology and a review of historical work completed to date, a 10 bcm/tonne stripping ratio was identified as a cut-off for resource estimates, which appears to be a reasonable economic limit for resource estimates. No portion of the Julia Creek Project area has a modelled strip ratio of more than 10 bcm/tonne, and therefore no areas have been excluded from the resource on this basis. |
| Metallurgical factors or assumptions |
The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made. |
No recent metallurgical studies have been conducted on recovery efficiencies and costs associated with treatment and recovery of both the vanadium Mineral Resource and the oil shale Petroleum Resources. Previously published work by CSR (CR24927) in 1973 indicated that hydrothermal leaching of Oil Shales at 340oC recovered about 12% of the vanadium. Hydrothermal leaching at 300oC with additives sodium bicarbonate and sodium carbonate in concentrations equivalent to 5 lbs Na2O per lbV2O5showed extraction efficiencies up to 90%. CRA took up a large tenement position around Julia Creek between 1991 and 1993. CRA drilled an additional 5 holes, compiled a database and summary report on previous Oil Shale exploration (CR24927) and conducted several technical studies into potential beneficiation options for the Oil Shale deposit. CRA concluded that treating the Oil Shales for crude oil was at that stage not a viable optiongiven that estimated |

| best case costs of between AUD 42 – AUD 48 per barrel were around AUD 10 – AUD 16 above the then projected long term oil price at the time. In determining a break-even strip ratio, a 90% recovery factor (in addition to the laboratory determined oil yield) for oil and 50% for vanadium have been used by Measured in this estimate. Detailed metallurgical studies will be required to identify the optimum treatment methodology for the recovery of oil and vanadium in addition to any other potential base metal biproducts (Cu, Mo, Ni and Zn). |
||
|---|---|---|
| Environmental factors or assumptions |
Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made. |
Measured has not conducted any environmental assessment in the concession area. |
| Bulk density | Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit. Discuss assumptions for bulk density estimates used in the evaluation process of the different materials. |
All tonnages have been adjusted to insitu density. 6% insitu moisture has been assumed, based on values for total moisture obtained from recent drilling, and documentation from historical reports(Coxhell and Fehlberg, 2000). |
Page 50
Julia Creek Project
Independent Geologist’s Report, June 2018
==> picture [76 x 43] intentionally omitted <==
| Classification | The basis for the classification of the Mineral Resources into varying confidence categories. Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data). Whether the result appropriately reflects the Competent Person’s view of the deposit. |
Resource classification is based on an assessment of the variability of critical variables (vanadium grade, oil grade and sedimentary unit thickness) through statistical analysis, geostatistical analysis and by an assessment of the degree of geological complexity (general dip and structure). The presence of assay results for vanadium has been set as the minimum requirement for a point of observation. Insufficient data on the critical variable (vanadium) exists for any meaningful geostatistical study to be conducted. Contours of modelled vanadium grade were therefore examined to investigate the spacial variability. Semi-variograms of Oil Shale Yield and unit thickness were investigated and found to have a range in excess of 10,000m in all cases. Minimum spacing between points of observation has been set to 4000m for the inferred category. No attempt has been made to classify the resource at indicated or measured status, at this stage of the project. Further acquisition of data (infill drilling) will be required to obtain an upgrade in confidence of the vanadium Resource. |
|---|---|---|
| Audits or reviews |
The results of any audits or reviews of Mineral Resource estimates. |
No audits or reviews of this estimate have been done to date. |
| Discussion of relative accuracy/ confidence |
Where appropriate a statement of the relative accuracy and confidence level in the Mineral Resource estimate using an approach or procedure deemed appropriate by the Competent Person. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could affect the relative accuracy and confidence of the estimate. The statement should specify whether it relates to global or local estimates, and,if local, state therelevant tonnages,whichshould |
The resource classification is considered to address the level of confidence in thickness and base metal/oil yield variability across the deposit on a global basis. In addition, the potential exists for geological loss due to the presence of faults which are not easily identified by the current drillhole spacing. |

Summary of SPE-PRMS Petroleum Resource Estimate
(Extracts from Measured Group Geology and Resource Estimate Report, 2018)
Note:
The Petroleum Resource found in the Julia Creek Project is unconventional as it is hosted as a solid hydrocarbon (kerogen) in the Toolebuc Formation oil shales. This type of Petroleum Resource is not evaluated in the same way as conventional oil and gas, and methods used to explore and estimate this style of Petroleum Resource are similar to that of a 'hard rock' Mineral Resource. Hence, the methodology for assessment and reporting the geology, exploration results of an unconventional Petroleum Resource is more akin to JORC Code, 2012, when compared to conventional oil and gas reporting.

There are no 1C or 2C resources as the points of observation (drill hole spacing) of the Oil Shale grade is insufficient to place reliable confidence on both grade and thickness continuity required for 1C or 2C resources.
The Petroleum Resource estimate is unrisked.
The SPE-PRMS report for the Julia Creek Oil Shale deposit was issued in May 2018.
The estimate of Mineral Resources for the Julia Creek Project, contained within EPM 25622, EPM 25681 and EPM 26429, and presented in this report have been carried out in accordance with the Guidelines for Application of the Petroleum Resources Management System (2011 Edition).
No portion of the Julia Creek Project area has an in-situ vertical stripping ratio that exceeds 10:1 BCM/tonne (waste/ore), and all ore with a stripping ratio less than 10:1 is considered to have reasonable prospects for eventual economic extraction.

Petroleum Resource Estimation
The Petroleum Resource found in the Julia Creek Project is unconventional as it is hosted as a solid hydrocarbon (kerogen) in the Toolebuc Formation oil shales. This type of Petroleum Resource is not evaluated in the same way as conventional oil and gas, and methods used to explore and estimate this style of Petroleum Resource are similar to that of a 'hard rock' Mineral Resource. Hence, the methodology for assessment and reporting the geology, exploration results of an unconventional Petroleum Resource is more akin to JORC Code, 2012, when compared to conventional oil and gas reporting.
The Petroleum Resource estimate is based on the discovered Petroleum Initially in Place (PIIP), which is estimated using a stratigraphic grid model.
The estimate is based on the following constraints and data:
-
The estimation methodology used is deterministic. The estimation is based on grids constructed for unit structure, thickness and oil grade parameters.
-
Interpretation of intersected stratigraphy is based on 41 pre-collared cored drill holes drilled to a maximum depth of 166.59 metres below surface for an aggregate of 3,473.32 metres.
-
Interpolation of oil grade parameters is based on composite results in 26 pre-collared cored drill holes drilled to a maximum depth of 151 metres below surface for an aggregate of 1,389 metres.
Page 55

Oil grade has been determined by modified Fischer Assay (ASTM D3940-90) on 73 core samples representing approximately 244.9m metres of cored material.
-
An in-situ grade cut-off of 40 litres per tonne on an air-dried basis (40L/tonne) has been applied.
-
The resource is contained within an elongate surface area of 115.8 square kilometres within Exploration Permits for Minerals 25622, 25681 and 26429.
-
A recovery factor of 0.9 has been applied to the in-situ estimate based on published recovery data from a number of conventional retort technologies both operating and under development.
-
The total estimate as at 30 May 2018 are entirely 3C resources. The exploration drilling density or points of observation is not sufficient define 1C or 2C resources.
-
The 3C estimate is unrisked.
All drilling data used to develop geological interpretations, develop an understanding of the geological continuity and build structural and grade models for the Julia Creek Project are contained in Appendix C of this report.
The Petroleum Resource estimate for the Julia Creek Project is summarised in the table below is estimated and reported as per the SPE-PRMS, 2011.

Notes:
-
The estimate uses a minimum cut-off oil yield of 40 L/tonne, rounded down to nearest million tonnes.
-
The total resource tonnage reported is rounded to reflect the relative uncertainty in the estimate and component horizons may not sum correctly.
-
There are no 1C or 2C Resources as the current points of observation (drill hole spacing) of the oil shale grade is insufficient to place reliable confidence on both grade and thickness continuity required for 1C or 2C resources.

Contingent Petroleum Resource Classification
Contingent Resources are those quantities of petroleum estimated, as of this report date, to be potentially recoverable from known accumulations using established technology or technology under development.
Commercial recovery of oil from Julia Creek shale has not been established and as such the Contingent Petroleum Resources cannot be classified as Petroleum Reserves. At Julia Creek, resource development is considered unclarified or not viable based on the current immature state of knowledge of commercial recovery due to one or more of the following contingencies:
-
Development requires the application and grant of a mining lease and environmental approvals from the Queensland Government based on a commercial mine and processing proposal; i.e. legal, environmental, social and governmental factors for development have not been either established or approved.
-
A commercial mine and processing development has not at this time been assessed against any current and forecast economic conditions to support commercial viability.
-
Commercial recovery is dependent on the suitability of Julia Creek Oil Shale to be processed in current retorting technology or technology under development.
-
Oil shale similar to those found at Julia Creek are currently mined and processed by long running retort processes in Estonia (Eesti-Energia/Enerfit) and Brazil (Petrobras/Petrosix) but have not been tested by QEM for suitability of recovery by these processes.
Geology and Geological Interpretation
Confidence in the sedimentary correlations is considered high as they are based on down holes geophysics, assays and core photographs. A secondary confirmation of the interpretation is the gridded model itself which shows good continuity between data points.
As a result, the current drilling density, interpreted geological and oil grade continuity subunit composites (CQL, OSU and OSL) is considered sufficient for the resource classification assigned (3C Resources). Closer spaced drilling will be required to upgrade the degree of resource confidence to quantify 1C and 2C resources.
This aspect is further described in Section 6.3 of the body of this Independent Geologist’s Report.
Sampling and Sub-sampling Techniques
This aspect is described in Section 6.5 of the body of this Independent Geologist’s Report.

Criteria Used for Resource Classification
Minimum spacing between points of observation was set to 4000 m for the 3C category. No attempt was made to classify the resource at 1C or 2C category at this stage of the project.
Further acquisition of data (such as infill drilling) will be required to achieve an increased confidence in geological continuity and support an upgraded classification of the Oil Shale Petroleum Resource.
Drillholes intersecting the Toolebuc Formation, with valid oil yield data exist beyond the last line of points of observation. These have been used as supportive data for:
-
structure continuity, as they provide accurate information related to the unit’s thickness; and
-
for grade continuity (see Section 6.4).
Based on these supportive data, the Petroleum Resource is classified as 100% 3C, of which 0% is extrapolated. The Petroleum Resource is unrisked.
The following figure shows the distribution of points of observation and supportive data for the Mineral Resource and Petroleum Resource estimates and the Resource Limits for the Julia Creek Project.
This aspect is described in Section 6.7 of the body of this Independent Geologist’s Report.
