MARKET RELEASE For Immediate Release 30 November 2018
HIGH-GRADE GRAPHITE MINERALISATION CONTINUITY CONFIRMED AT ULEY
Assay Results Highlights
-
Assay results confirm continuity of high-grade flake graphite mineralisation
-
Very high-grade near-surface mineralisation within the Uley Pit 2 area
-
Very high grades of graphite including grade exceeding 55% gC
Uley 2 Extensional Drilling Campaign
Quantum Graphite Limited (QGL) is pleased to announce final results from the extensional drilling campaign at the Company’s Uley Graphite Mine (refer previous announcements dated 24 August 2015 and 30 October 2015) conducted in 2014 and 2015.
The extensional drilling campaign focused on the Uley Pit 2 area and was designed to confirm the dip and strike continuity of the mineralisation and provide supporting data for feasibility studies in respect of Uley mine expansion.
These assay results confirm that the very-high grade graphite mineralisation is continuous and remains open in a southerly direction and importantly, confirm the results in the earlier announcements referred to above. The drill holes were collared along strike from the proposed Uley Pit 2 and in accordance with the Company’s interpretation of the Transient Electro Magnetic (TEM) geophysical signature (Figure 4 below) which provides the basis for its exploration model and long-term development strategy.

APPENDIX 2
JORC Code, 2012 Edition Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria JORC Code explanation |
Criteria JORC Code explanation |
Commentary |
|---|---|---|
| Sampling techniques Nature and quality of sampling (e.g. 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 (e.g. ‘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 (e.g. submarine nodules) may warrant disclosure of detailed information. |
Triple tube Diamond (HQ3) drilling was employed to generate core for logging and sampling. Mineralised samples were submitted for assay on typically one metre intervals. Duplicate and standard samples were inserted typically every 20th sample. Diamond core was cut in half using a diamond impregnated blade on a core saw and half-core samples were sent to ALS Global for assay. |
|
| Drilling techniques Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so,bywhat method,etc.). |
Drill holes were drilled at -60-degree dip on a 090 azimuth. Diamond drilling was undertaken using triple tube HQ3 (61mm diameter) core from collar to End of Hole. |
|
| 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 recovery was recorded at the drill site and during core logging and measured for every core run. Sample recovery is deemed to be adequate for resource estimation purposes. |

|---|---|---|
| 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. |
100% of the drill holes were geologically and geotechnically logged by qualified geologists, recording relevant data to a set database structure. All logging included lithological features, mineral assemblages, mineralisation percentage estimates and geotechnical information suitable for the development of geology models and pit slope design criteria. |
|
| Sub-sampling techniques and sample preparation If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. 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 beingsampled. |
Sample preparation is consistent with industry best practice. Field QC procedures involved the use of certified reference material assay standards, blanks and duplicates for Company QC measures, and laboratory standards, replicate sampling and barren washes for laboratory QC measures. The insertion rate of each of these QAQC measures averaged 1:20. Half-diamond core samples averaged 1m in length, and are deemed appropriate for the material and analysis method. |
|
| 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 (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
The samples were prepared at ALS Global (Adelaide), including crushing entire sample >70% -6mm, splitting and retention of 50% sample weight, and pulverising. The prepared samples were sent to ALS global (Brisbane) for analytical procedures C-IR18, C- CAL15, CIR17 and C-IR07 by LECO analyser to determine graphitic carbon, inorganic carbon by difference, organic carbon and total carbon. The detection limits and precision for graphitic carbon analysis are considered to be adequate for the purpose of future resource estimations. The laboratory procedures are considered to be appropriate for reporting purposes. Company QAQC samples inserted at 5% representivity demonstrate the accuracy and precision of the graphitic carbon to be satisfactory. |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaininga licence to operate in the area. |
The Company owns 100% interest in the EL4778 tenement. The tenement is in good standing and there are no known significant impediments to exploration in the area. |
| Exploration done by other parties |

No other parties were involved in this exploration program. |
| Geology | Deposit type, geological setting and style of mineralisation. |
The Uley graphite deposit is a high-grade coarse-flake mineralised envelope within the broader “Mikkira" graphite resource. Uley graphite mineralisation is hosted by the Cook Gap Schist, a partially migmatised medium grained biotite+/-garnet+/-muscovite+/- sillimanite-quartzofeldspathic schist/gneiss with leucocraticpegmatite sweats. |
| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill holecollar o elevation or RL (Reduced Level –elevation above sea level in metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interceptiondepth 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 (e.g. 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 clearlystated. |
No top cuts have been applied to the results reported in this announcement. A nominal 10% graphitic carbon lower cut-off has been applied in the determination of significant intercepts. High grade intercepts within broader low-grade intervals have been separated as "including" results. No metal equivalent values are used in this report. |
| 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 drill hole 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 (e.g. ‘down hole length, true width not known’). |
Drill holes intersected mineralisation at near perpendicular to the strike orientation of the host lithologies. All drill holes were orientated at -60 degrees on a bearing of 090. |
| 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 drill hole collar locations and appropriate sectional views. |
See figures in release |
| 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 reportingof Exploration Results. |
Representative reporting of significant intercepts has been affected within this report. |
| 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 contaminatingsubstances. |
The Company has previously reported a Mineral Resource in accordance with JORC (2012) guidelines at the Uley 2 deposit. |
