ASX RELEASE 10 August 2015
Tick Hill Surface Gold Project RESULTS – TAILINGS DRILLING PROGRAM
-
Analytical results from the first stage of the tailings drilling program received.
-
Better than expected gold grades justify a second stage drilling program to further define and delineate a potential gold resource within the tailings storage facility.
-
Average grades of 1.04 g/t Au for the tailings dam (overall), 1.42 g/t Au for the eastern paddock and 0.73 g/t Au for the western paddock.
-
Tailings Dam covers approx. 8 ha and could contain between 600,000-650,000t of tailings material, based on historical records.
-
A second stage follow-up program planned to commence during late August 2015.
Superior Resources Limited ( ASX Code: SPQ ) ( Superior or the Company ) is pleased to confirm that assay results from a 24 hole tailings reconnaissance drilling program have been received. The results of the initial program are encouraging with some intercepts returning better than expected gold grades.
The program also included a series of drill holes in the Tailings Decant Pond and over a soil geochemical anomaly located within an area of alluvium. A summary of the drilling program is detailed in Table 1.

Superior Resources Limited
The reconnaissance drilling program was conducted by Superior together with joint venture partner Diatreme Resources Limited ( DRX ) during the period 17 July 2015 to 20 July 2015. The program utilised a DRX-owned air-core drill rig and DRX staff.
Tailings Dam Morphology
The original Tick Hill Gold Mine processing plant comprised crushing and milling circuits feeding into a carbon-in-leach (CIL) gold recovery circuit. Tailings material from the plant was discharged into the tailings dam, which comprises two “paddocks” of a “turkeys nest” construction. A perimeter embankment with a clay core retains the tailings. Wall heights range from 6m to 10.5m. A Tailings Decant pond designed to receive overflow water is located adjacent to the northern wall of the Tailings Dam (Figure 1). Since decommissioning the surface of the Tailings Dam and Tailings decant Pond have been capped and seeded.

Estimated Tonnage
The total reported historical production at Tick Hill was 705,000t for 15,900kg Au at 97% recovery.
Tailings Dam Drill Results
The reconnaissance drilling program on the Tailings Dam was designed as an “orientation” program to provide an initial indication of the nature of the tailings deposit. The drilling was conducted on a 50m x 50m spaced grid over the two Tailings Dam paddocks.
Superior considers the results to be significant and encouraging. A summary of the results is set out in Table 2.

An overall grade of 1.04 g/t Au was achieved from a total of 173 samples. The samples showed minor variability and all tailings material is mineralised.
The eastern tailings paddock returned an average grade of 1.42 g/t Au from 78 samples, whilst the western tailings dam which has been filled to a slightly higher elevation, returned 0.73 g/t Au from 91 samples. Tailings material from the decant pond was also mineralised, with an average grade of 0.46 g/t Au returned from the 7 holes sampled (11 samples).
A summary of the drill hole details and average gold grades are set out in Table 3. Drill hole locations are diagrammatically shown in Figures 2 and 3.

Further Work – Tailings Dam
The positive results from the reconnaissance drilling program warrants the planning of a second stage follow-up drilling program. The second stage program will include infill drilling and the collection of samples for metallurgical test work to enable the assessment of potential gold processing and recovery options. Consideration will also be given to determine the most appropriate method for drilling of the tailings in order to ensure consistent and accurate recovery of sample material.
Alluvium Soil Geochemical Anomaly
ASX Release – 10 August 2015 - Page 3 of 12
Superior Resources Limited
Results from the reconnaissance drilling of a historical soil gold geochemical anomaly NW of the open pit to assess the alluvial/eluvial potential were generally disappointing, with only one significant assay returned from the upper section of one hole. Weathered bedrock was encountered at generally shallow depths (between 1m and 2m) and it appears that there is insufficient mineralisation and volume of alluvium to warrant further investigation at this location.
Technical details concerning the deposit, exploration drilling program and the exploration results are presented in Appendix 1 (JORC Table 1).

Section 1 Sampling Techniques and Data
| 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. |
Air core drilling was used to obtain 1m samples from which ~3kg was pulverized to produce a 50g charge for fire assay. Samples are 1m down hole intervals of air-core drill cuttings collected from rig-mounted cyclone, the entire sample was collected and submitted to the laboratory, with riffle splitting of those samples >3.2kg in weight prior to pulverising. 1m sample intervals are considered appropriate for first pass drilling of mineralised tailings. |
| Drilling techniques |
Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). |
Vertical NQ air-core drilling utilizing blade bit, 3m drill runs. Drilling technique was continually adjusted to suit the prevailing drilling conditions (e.g. dry, moist, wet with variable clay content). |

Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. The total length and percentage of the relevant intersections logged. |
Geological logging of the total hole by field geologist, with retention of sample in chip trays to allow subsequent re-logging / re-interpretation of data. Tailings dam is capped by ~0.6m rock and topsoil, with a clay base – both were readily identifiable from the tailings material. Qualitative logging includes material lithology and colour. Logging data stored in both hardcopy and digital format. |
| 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 being sampled. |
No sub-sampling on site, entire sample submitted to ALS laboratory in Townsville for sample preparation. Sample was dried, weighed, riffle split if >3.2kg, and pulverised. 50g sub-sample for assay is riffle split from homogenized pulverised sample. No field duplicates were submitted from this exploration program. Sample size is considered appropriate for the material sampled. |

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. Whether sample compositing has been applied. |
Drill holes spaced at 50m x 50m. Drill spacing and distribution is sufficient to allow reporting of exploration results. Downhole sample compositing has been applied for reporting of exploration results as a total hole intersection. |
| 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. |
Vertical drill holes are considered appropriate for unbiased sampling of the target mineralisation. Exploration drilling has been completed on a regular 50m x 50m within each paddock of the tailings dam. The dam was filled from the southern end, with tailings and water flowing north along the natural slope of the ground surface. There are no comprehensive records of the utilisation of the tailings dam. |

||
| 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. |
Exploration results are reported as a length weighted average of the total hole intercept, as the basal sample was truncated at the intersection of the clay base and is typically <1m. No minimum or maximum grade truncations have been applied. |
| Relationship between mineralisatio n 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 (eg ‘down hole length, true width not known’). |
As the mineralization is associated with tailings fill a maximum beaching slope of 2° can be assumed. All drilling is vertical, hence the drill intersection is essentially equivalent to the true width of mineralization. However, the geometry and controls of grade distribution within the tailings are unknown at this time. |
| 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. |
A map of the drill collar locations and the tailings dam is attached. |
| 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. |
Not applicable, all results have been reported. |
