Further Drilling Success Beneath the Mt Boppy pit
Highlights:
-
Following on from the exceptional extension drilling announced on 24 August (MBGC0042: 10 m @ 34.48 g/t Au, and MBGC0043: 14 m @ 14.51 g/t Au) this again confirms the existence of exciting grades of ore below the current pit shell.
-
Assays from an additional 2 holes from MKR’s surface drill program have been received and a geological interpretation of the results completed.
-
Best intercepts from two southernmost holes targeted at down-dip and along strike extensions of previously reported intercepts and adjusted for stope dilution:
oHole MBRC016: 10 m @ 4.05 g/t Au from 158 m downhole depthoHole MBGC017: 18 m @ 6.24 g/t Au from 166 m downhole depth -
Intercepts are ~10-30m below the current planned pit floor confirming the existence of ore grade mineralisation outside the current pit shell
-
3D geological modelling and structural interpretation of the wider Mt Boppy mining camp area has defined areas for shallow drill testing identifying an additional 13,500m shallow drill program planned to commence in October to test the prospective Baledmund Formation where it is cross-cut by north-trending structures
-
Resource in-fill drilling to upgrade the Wonawinta 52moz Ag Inferred Resources continues to plan, with almost 50% of the program now complete
Resource extension at the Mt Boppy gold resource is ongoing and the surface drilling results have contributed to a better understanding of the controls and likely extent of high grade mineralisation at and below the current design pit floor. Three drill holes collared at surface on the western side of the pit have now been completed with significant results following:
MBRC016 158 m-173 m (15 m) average 3.33 g/t Au (stope fill 168 m-173 m) OR 10 m @ 4.05 g/t Au adjusted for stope fill dilution;
MBRC017 166 m-186 m (20 m) average 5.89 g/t Au (stope fill 184 m- 186m) OR 18 m @ 6.24 g/t Au adjusted for stope fill dilution.

These two intercepts are approximately 10 m to 30 m beneath the current planned pit floor. Following the exceptional extension drilling announced on 24 August (MBGC0042: 10 m @ 34.48 g/t Au, and MBGC0043: 14 m @ 14.51 g/t Au) this again confirms the existence of exciting grades of ore below the current pit shell.
MBRC018 was planned to intersect the mineralised zone some 35 m north of MBRC017 but deviated significantly in dip and azimuth such that it passed to the north and underneath the downdip limit of mineralisation.
The Company undertook to develop three-dimensional modelling of the wider Mt Boppy camp and neighbouring tenements and is well advanced in this direction. This interpretation of the wider area around Mt Boppy has highlighted areas of no previous drill testing or other exploration where prospective Baledmund Formation is cross-cut by north-trending structures. These areas are largely covered by alluvium and present targets for shallow (RAB or aircore) drilling. Preparations are underway to complete statutory approvals for these drill programs during September, with the programs (comprising circa 13,500 metres of drilling) planned to commence in October.
Technical detail
The reported drill holes were part of a program designed to follow up previously reported high grade intercepts in the hangingwall (west side) of back-filled stopes in the Mount Boppy gold deposit. High grade zones were encountered in historic drilling and mining higher in the deposit, associated with dip and strike flexures of the Mount Boppy Main Lode.
Holes in this drill program were collared on the 280 m RL (natural topographic surface) and drilled to the east to intersect steeply west dipping mineralisation at a high angle. All drilling utilized the Reverse Circulation technique to obtain samples every metre downhole. Sub-samples for analysis were split from the primary sample using a riffle splitter attached to the drill rig. Samples were assayed for gold at the ALS laboratory in Orange by Fire Assay. Full details of drill hole sample results for reported holes are given in Table 3.
Figure 1 shows a long section view looking east of the Mount Boppy deposit in the vicinity of reported drill hole intercepts. The grey shaded background is a surface representing the western margin of stoping that occurred when Mount Boppy operated as an underground mine from 19001923. During underground mining these stopes were backfilled with tailings sands that contain significant gold grades and form part of the Mount Boppy resource. Figure 2 shows the location of reported drill holes, located on the 280 m RL on the western edge of the Mount Boppy pit. Figure 3 and Figure 4 show east-west oriented cross sections through the reported drill holes, with the current design pit shell and backfilled stope volumes indicated.
The bold dashed lines on Figure 1, Figure 3 and Figure 4 show the interpreted extent of high grade mineralisation in the hangingwall of stoping based on drilling results so far. This zone corresponds with a strike and dip flexure of stopped mineralisation, reflecting a strong structural control on veining. In-pit RC drilling will further define the extents of high grade mineralisation in this area and test the preliminary geological model presented here.

Manuka’s Executive Chairman Dennis Karp said: “We are naturally very pleased to continue to see high grade gold intercepts outside the existing pit shell at Mt Boppy. This augers well for growing the existing resources there, one of the key priorities of the Company’s three-stage exploration program. The 3-D modelling we have now completed of the wider Mt Boppy camp and neighbouring tenements has delivered highly encouraging results which we will commence drilling in the very near term with a large, shallow RC program and could further transform our understanding of the prospectivity of the Mt Boppy region.”

JORC CODE, 2012 EDITION – TABLE 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | |
|---|---|---|
| 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. |
• Reverse Circulation (RC) drilling was used to collect samples from 1 m intervals downhole. • Sampling utilised a rig-mounted cyclone and riffle splitter to obtain 1 m samples weighing 1.5 kg to 3.0 kg that was pulversised and split to produced a 50g charge for fire assay. • Samples were collected from MBRC016 and MBRC017 starting at a downhole depth of 99 m and continuing to the end-of-hole. Sampling of MBRC018 started at 123 m downhole until the end-of-hole. Historical drilling results and geological understanding was sufficient to be confident that there was no mineralisation in the unsampled parts of the drill holes. |
| 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). _ |
• RC drilling using a 5½ inch face-sampling bit was utilized for all RC drill holes. |
| 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. |
• Sample recoveries were visually assessed from chip pile sizes and split sample weights and classified as ‘good’ or ‘poor’. Where backfilled stope material and strongly broken zones were sampled, sample loss was commonly noted. • There is no relationship between sub-sample weights and grade. • All samples were recovered dry and there is no noted sample bias from loss/gain of fines. |
| 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. |
• Lithology, quartz veining percent, alteration style and intensity and presence/estimated amount of sulphides was recorded on a per metre basis for the entire drill hole. • Note was also made from drillers’ remarks and drill plods on encountering water or voids. |
| 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. |
• Sub-samples were obtained from a riffle splitter on the drill rig. • Off-siders regularly inspected and cleaned the splitter. The splitter was removed during hole cleaning and returned to position upon commencement of drilling. • One duplicate sample within each drill hole was collected. • Gold is finely disseminated and associated with sulphides in quartz veins and the RC sub-sample size is considered appropriate. |
| Quality of assay data and |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • Forgeophysical tools, spectrometers, handheld XRF |
• All samples were analysed at ALS Laboratories Orange using Fire Assay with a 50g charge. Fire Assay is considered a ‘total’ technique for non-coarse gold. • Blank and standard samples were included in batches sent |

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) andprecision have been established. |
to ALS at a rate of 1 standard and one blank for every 30 routine samples. No issues were noted with blank and standard analysis. • ALS laboratories undertake internal QC checks including standards, blanks and duplicates. |
| 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. |
• Significant intersections have been verified by other company personnel and consultants. • RC holes from this programme are not twin holes. • Samples were collected in pre-numbered bags with sample numbers assigned to the appropriate intervals and entered into a relational database (MS Access). Assay results were received from laboratories in digital format and matched to sampled intervals using database queries. • No adjustments have been made to assay data. |
| Location of data points |
• Accuracy and quality of surveys used to locate drill holes (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. |
• Drill collars were located using Total Station surveying to an accuracy of less than 1cm in X, Y and Z using Map Grid of Australia zone 55 coordinate system. • Collar azimuth and dip were determined at time of rig setup using a compass-clinometer. • Downhole dip surveys were taken within rods every 30 m- 50 m during drilling to check the hole path. • Downhole surveys for azimuth and dip were undertaken at the end of the hole every 30 m downhole using a Reflex EZ-Trac single shot tool. |
| 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. • Whether sample compositing has been applied. |
• Reported drill holes were part of an RC program designed to test the depth extent of high-grade areas intersected during previous in-pit RC drilling. The spacing is considered sufficient for definition of Indicated to Measured resources. • No 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. |
• Drilling was oriented perpendicular to the strike of mineralisation and at an angle of approximately 50° to the dip. • Sampling orientation is considered to have achieved unbiased sampling. |
| Sample security |
• The measures taken to ensure sample security. |
• Samples dispatched to ALS in Orange were bagged in larger polyweave sacks secured with zip ties and delivered by a local freight company. Sample numbers received by ALS were checked again dispatched numbers. |
| Audits or reviews |
• The results of any audits or reviews of sampling techniques and data. |
• No audits/reviews of sampling techniques and data have been undertaken on this drill program |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | JORC Code explanation | |
|---|---|---|
| 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 obtaining a licence to operate in the area. |
• ML1681, ML311, MPL 240, GL 3255, GL 5836, GL 5848, and GL5898 and exploration licence EL 5842 are all held by Mt Boppy Resources Pty Ltd. (wholly owned by MKR) • The property on which the Mount Boppy mine situated is Crown Land. • A Native Title Agreement is in place with the traditional owners. • The Company notes that no land within the licence area may be classified as sensitive land. No further approvals other than those required under the Mining Act 1992 are required. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• The deposit was first discovered in 1896 and mined by underground methods up to 1923. • Various companies have conducted exploration activities around Mt Boppy since the 1960s, with treatment of tailings and openpit miningupuntil 2015. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The Mount Boppy deposit is located in the northern part of Devonian Canbelego-Mineral Hill Rift Zone, flanked by the Kopyje Shelf, on the far eastern side of the Cobar Basin. • Mineralisation occurs in brecciated and silicified sediments and quartz veining developed along a west-dipping fault that down- throws Devonian aged Baledmund Formation rocks on its western side against Orodovician age Girilambone Group rocks on it eastern side. • The Main Lode strikes approximately north-south and dips at approximately 70-80° west. • The best mineralisation in wall rocks occurs within the Baledmund Formation rocks on the western side of the Main Lode where the lode has a shallower dip. • Historical underground workings were supported with timber and back-filled with tailings sands from processing. Sand fill samples grade between 0.05 g/t Au and 38 g/t Au with an average of 3.5 g/t Au. • Mineralisation is predominantly gold, associated with grey quartz veins and minor pyrite. |
| 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 hole collaro elevation or RL (Reduced Level – elevation abovesea level in metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interception deptho 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. |
• Drill hole information is included in tabulated form in the body of the announcement. |
| 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. |
• Reported drill hole intercepts have been averaged according to sample length: since all RC sample intervals are the same length the reported average grade is the arithmetic average of all samples in the interval. • Aggregate intercepts define mineralisation above a cut-off of 1 g/t Au with a maximum of 2m of internal dilution. |

www.manukaresources.com.au
| Criteria | JORC Code explanation | |
|---|---|---|
| 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 _(eg ‘down hole length, true width not known’). _ |
• True widths are estimated to be 75% of the down-hole intercept width. |
| 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. |
• Diagrams and tabulations of intercepts are included in the body of the report. |
| 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. |
• The drill hole intercepts reported represent a high grade portion of the Mount Boppy gold deposit and are not representative of the entire dip and strike extent of mineralisation. • Cross sections of entire drill hole results are provided in the body of the 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 contaminating substances. |
• Boppy mineralisation is processed at MKR’s Wonawinta plant, which uses a carbon-in-leach (CIL) process to extract gold, generally achieving recoveries of between 75% and 80%. |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
• RC drilling from within the pit will be planned to better define the extent of identified higher grade hangingwall mineralisation within the area indicated on Figure 1 of this announcement. |
