- Drilling continues at Boda and Boda Two, testing extensions and adding definition to the identified mineralised systems. An air-core drilling rig and one high-capacity RC drilling rig will be mobilised onsite next month supporting the ongoing diamond core drilling at Boda, Boda Two, as well as regional targets within the NMPP. Further assay results are expected to be released when available.
Alkane Resources Limited (ASX: ALK) (‘Alkane’ or ‘the Company’) announces the intersection of further high-grade mineralisation at the Company’s Boda Prospect in Central New South Wales. Boda is a landmark porphyry gold-copper system, within the Northern Molong Porphyry Project (‘NMPP’), which Alkane believes has the potential to be a large, tier one gold-copper project.
Alkane Managing Director, Nic Earner, said: “These latest results give further insight into both the high-grade brecciated zone and the sheer size of the Boda complex and adjacent complexes within the Northern Molong Porphyry Project.
“Our drilling program continues with the aim of both in-filling and expanding the mineralised system. We expect that the ongoing drilling program will validate the Company’s growing confidence in the scale of the high-grade zone at Boda.
“Along with the Company’s nearby Tomingley Gold Operations (‘TGO’), Alkane is actively working towards its stated ambition of becoming Australia’s next multi-mine gold producer.”
Alkane’s Technical Director, Ian Chalmers, is providing a detailed update on Boda, and Alkane’s ongoing exploration program, at the NSW Mining Exploration and Tenures Forum on 3 May 2021. The presentation, while technical in nature, will be lodged on the ASX platform. The Company looks forward to providing further insight and drilling results from Boda in the coming weeks and months.

Northern Molong Porphyry Project (NMPP) Alkane Resources Ltd 100%
The Project is located at the northern end of the Molong Volcanic Belt, within the Eastern Lachlan Orogen (Macquarie Arc) in Central West of NSW and is considered highly prospective for large scale porphyry and epithermal gold-copper deposits.
Exploration in the NMPP has identified five discrete magnetic/intrusive complexes – Kaiser, Boda, Comobella, Driell Creek and Finns Crossing – within a 15km northwest trending corridor. The corridor is defined by monzonite intrusives, extensive alteration and widespread, low-grade, gold-copper mineralisation.
==> picture [427 x 369] intentionally omitted <==
A major RC and diamond core drilling program for approximately 30,000 metres commenced in July 2020. The program was designed to test the dimensions and extensions to the large low-grade mineralised envelope as well as any internal high-grade zones at Boda. In addition, the drilling is testing other known gold-copper mineralisation occurrences and co-incident IP anomalies within the 15km monzonite intrusive corridor that extends from Boda to Finns Crossing.
Assays received from the current drilling program at Boda and Boda Two comprised of seven diamond core holes for a total of 10,091 metres testing the strike and depth extensions of the gold-copper porphyry mineralisation at the Boda prospect (discovery hole KSDD003 - 502m @ 0.48g/t Au, 0.20% Cu from 211 metres; ASX Announcement 9 September 2019 and Boda Two conductive anomaly KSDD022 - 292m @ 0.66g/t Au from 867 metres; ASX Announcement 11 November 2020 ).

Boda Prospect
Two diamond core holes (KSDD029 and KSDD031) spaced 150m part and collared northeast, were planned to test the strike and down plunge extension to the sulphide cemented breccia zone intersected initially by KSDD007 (96.8m grading 3.97g/t Au, 1.52% Cu from 768 metres - ASX Announcement 23 March 2020). KSDD029 swung acutely to the south finishing approximately 200m off target and missing the breccia. KSDD031 intersected the down dip extension of the sulphide cemented breccia zone with significant intercepts of:
KSDD031 13m grading 0.44g/t Au, 0.35% Cu from 645m and 383.2m grading 0.80g/t Au, 0.31% Cu from 775m incl 204m grading 1.40g/t Au, 0.51% Cu from 776m incl 101m grading 2.47g/t Au, 0.83% Cu from 824m incl 70m grading 3.04g/t Au, 0.92% Cu from 829m
KSDD031 has determined an approximate 100m down dip extension below previous drilling to the steeply northeast plunging sulphide cemented breccia. The breccia is hosted within shallow dipping stratigraphy comprising of mafic to intermediate lavas, sills and volcaniclastics with intense calc-potassic alteration. Approximately 100m down hole from the breccia is an equigranular feldspar-hornblende monzonite intrusive (1,100m – 1,220m down hole) that is variable mineralised hosting sheeted quartz veins with chalcopyrite – pyrite ± molybdenum. The timing of the monzonite with the breccia mineralisation is uncertain and is being resolved.
The breccia shows apparent sulphide zonation with the upper intercepts more pyrite rich, zoning towards the centre to more chalcopyrite rich with increasing Au-Cu grades. The breccia has now been intersected by drill holes KSDD007, KSDD011, KSDD012, KSDD028, KSDD031 and KSRC033D and at this early stage indicates that the breccia is approximately 50m in true width, thickening up plunge. The breccia is open along strike to the northwest, and down dip. Diamond core drilling is underway testing down plunge and RC drilling planned to commence in June 2021 to test its shallow expression up plunge.

All three drill holes intersected extensive gold-copper porphyry mineralisation hosted in strongly calcpotassic altered mafic to andesitic volcanics. KSDD015 intersected a similar pyrite-magnetite-calciteactinolite breccia with an intercept of 113m grading 0.39g/t Au, 0.16% Cu from 764m. The breccia is observed as texturally and mineralogically very similar to the high-grade breccia intersected by KSDD031 and is either a lateral displacement of the same breccia or a separate breccia zone within Boda. Significant molybdenum (Mo), copper and gold mineralisation were intersected by KSDD016 including 42m grading 0.56g/t Au, 0.54% Cu, 130ppm Mo from 764m in northern margin of Boda. This zonation of metals suggests a possible proximal magmatic source to the Boda system.
Boda Two Prospect
An electrical geophysics survey (3D-IP) previous completed over a 6km long north-south target corridor of Boda volcanic stratigraphy identified a strongly conductive target at the Boda Two prospect (ASX Announcement 19 May 2020). The anomaly was drill tested with KSDD022 intersecting strong pyrite mineralisation with impressive gold grades of 292m @ 0.66g/t Au from 867 metres ( ASX Announcement 11 November 2020 ). Two follow up diamond core holes (KSDD023 and KSDD030) were completed at Boda Two.
KSDD023 collared 100m north of KSDD022 and above the conductive IP feature, intersected strong

disseminated pyrite mineralisation with gold enrichment similar to the pyrite rich zone positioned on the eastern shoulder of the Boda mineralisation with significant results of:
KSDD023 520m grading 0.24g/t Au, 0.03% Cu from 645m Incl 24m grading 0.43g/t Au, 0.12% Cu from 935m
KSDD030 collared 200m west of KSDD022 and drilled immediately west of the IP conductive anomaly, intersected a large package of volcanic stratigraphy comprising of intermediate-mafic composition lavas and sills with extensive alteration. The substantial gold-copper mineralised intercept shows intense calcpotassic alteration with zones of magnetite-calcite brecciation and calcite - chalcopyrite ± bornite veining, with significant results of:
KSDD030 1,483m grading 0.15g/t Au, 0.10% Cu from 241m incl 16m grading 0.64g/t Au, 0.24% Cu, 15ppm Mo from 382m also 41m grading 0.32g/t Au, 0.21% Cu from 377m
The drilling at Boda Two has identified a broad zone of low-grade gold-copper porphyry mineralisation with a gold enriched pyrite zone of mineralisation positioned on its eastern margin. Further drilling is planned to continue to define the extensions to the mineralisation and to identify high-grade zones focused within breccias and intrusions.

The following tables are provided to ensure compliance with the JORC Code (2012) edition requirements for the reporting of exploration results.
JORC Code, 2012 Edition – Table 1 NORTHERN MOLONG PORPHYRY PROJECT – Boda, Boda Two May 2021 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. |
• Diamond core drilling was undertaken by Ophir Drilling Pty Ltd • DD sample intervals were defined by geologist during logging to honour geological boundaries, cut in half by diamond saw, with half core sent to ALS Laboratories • RC drilling was undertaken by Strike Drilling Pty Ltd • RC samples are collected at one metre intervals via a cyclone on the rig. The cyclone is cleaned regularly to minimise any contamination |
| • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
• Sampling and QAQC procedures are carried out using Alkane protocols as per industry best practice |
|
| • 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. |
• Core was laid out in suitably labelled core trays. A core marker (core block) was placed at the end of each drilled run (nominally 3m) and labelled with the hole number, down hole depth, length of drill run. Core was aligned and measured by tape, comparing back to this down hole depth consistent with industry standards. Half core is sampled with a Corewise automatic core saw. • RC Drilling – the total sample (~20-30kg) is delivered via cyclone into a large plastic bag which is retained for future use if required. A sub-sample of approximately 1kg is spear sampled from each plastic bag and composited to make a 3 metres sample interval. If strong mineralisation is observed by the site geologist this is sampled as a final 1m interval instead. The 1m intervals forming composite samples assaying ≥0.10 g/t Au or ≥0.10 % Cu are resplit using a cone splitter on the rig into a separate calico at the time of drilling and re-submitted to the laboratory for re-assay. • Gold was determined by fire assay fusion of a 50g charge with an AAS analytical finish • A multi-element suite was determined using a multi-acid digest with a ICP Atomic Emission Spectrometry or ICP Mass Spectrometry analytical finish. |
|
| 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). |
• Reverse circulation (RC) drilling using 110mm rods 144mm face sampling hammer • Triple tube diamond drilling with PQ3/HQ3 wireline bit producing 83mm diameter (PQ3) and 61.1mm diameter (HQ3) sized oriented core. |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. |
• DD - core loss was identified by drillers and calculated by geologists when logging. Generally ≥99% was recovered with any loss usually in portions of the oxide zone |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| • Triple tube coring was used at all times to maximise core recovery with larger diameter (PQ3) core or RC precollars used in the oxide zones. • RC sample quality is assessed by the sampler by visual approximation of sample recovery and if the sample is dry, damp or wet. |
||
| • Measures taken to maximise sample recovery and ensure representative nature of the samples. |
• Sample quality is qualitatively logged • Core drilling completed using HQ triple tube to maximise core recovery • A high capacity RC rig was used to enable dry samples collected. Drill cyclone is cleaned between rod changes and after each hole to minimise cross-hole contamination. |
|
| • 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. |
• There is no known relationship between sample recovery and grade |
|
| 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. |
• Each one metre interval is geologically logged for characteristics such as lithology, weathering, alteration (type, character and intensity), veining (type, character and intensity) and mineralisation (type, character and volume percentage) |
| • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography |
• Mostly logging was qualitative with visual estimates of the various characteristics. In addition, magnetic susceptibility data (quantitative) was collected as an aid for logging • All drill holes were geologically logged into Geobank Mobile, followed by validation before importing into Alkane’s central Geobank database • All drill holes were logged by qualified and experienced geologists |
|
| • The total length and percentage of the relevant intersections logged |
• All drill holes were logged in full |
|
| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. |
• Core sawn with half core samples submitted for analysis |
| • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. |
• Each one metre interval is spear sampled with 3m composite samples collected in a calico sample bag and forwarded to the laboratory. Where strong mineralisation is observed by the site geologist, instead of compositing, this is individually sampled from the cone splitter on the RC rig as a 1 metre interval into a calico bag and forwarded to the laboratory. • The 1m intervals forming composite samples assaying ≥0.10 g/t Au or ≥0.10 % Cu are resplit using a cone splitter on the rig during the time of drilling and re-submitted to the laboratory for re-assay. |

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. |
• All four licences (EL4022, EL6209, EL8261 and EL8887) in the Northern Molong Porphyry Project are owned 100% by Alkane. |
| • 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. |
• All exploration licences are in good standing. EL4022 expires on 13 August 2026. EL6209 expires on 11 March 2023. EL8887 expires on 6 February 2026. EL8261 expires on 30 April 2023. |
|
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Significant historical drilling activity has been conducted within the bounds of EL4022. • BODA PROSPECT: CRA Exploration/Rio Tinto completed a small IP survey and several reconnaissance RC holes in the Boda Prospect area in 1995. The results identified sporadic, shallow low-grade intervals of gold mineralisation hosted within a sequence of monzonites, diorites and intermediate volcanics. Sampling was performed by collecting spear composites from 3m drill runs, assayed by aqua regia digest and fire assay-AAS and ICP finishes. Amax Mining Inc/Woodsreef Mines grid sampled the residual soil profile and analysed for Cu, Pb and Zn. A coherent +250 ppm Cu soil anomaly was outlined with a strike length of over 1000m and a maximum of 1.25% Cu, in the -80-mesh sieve fraction. Grid based rock chip sampling produced up to 5.4% Cu and 42ppm Au. • Within EL6209 records show 14 AC (170m), 78 RC (7591m) and 45 DD holes (7833m) = 15,594m. • KAISER PROSPECT: Under-reporting of historical exploration drill results from the Kaiser Prospect is suggested by preliminary metallurgical test work by previous explorers and is supported by a drill hole (KSRC001) completed by Alkane. This can be partly explained by the partial digests and analogue equipment commonly used in the 1970s |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The area is located at the northern extent of the Molong Volcanic Belt, a geological region considered highly prospective for and host to several economically important examples of porphyry Au-Cu mineralisation e.g. Cadia Valley alkalic porphyry cluster. |
| 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: oeasting and northing of the drill hole collar oelevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar odip and azimuth of the hole odown hole length and interception depth ohole length. |
• See body of announcement |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| • 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. |
• All drill holes have been reported in this 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. |
• Exploration results reported for uncut gold grades, grades calculated by length weighted average |
| • 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. |
• Reported intercepts are calculated using a broad lower cut of 0.1g/t Au and/or 0.05% Cu although grades lower than this may be present internally (internal dilution). Internal dilution can be significant because of the type of bulk mining techniques used to extract this style of mineralisation but are limited to <24% for the purpose of calculation. • No top cut has been used. • Short intervals of high grades that have a material impact on overall intersection are reported as separate (included) intervals |
|
| 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’). |
• It is apparent on the sections and the report descriptions that the overall geometry of the porphyry mineralisation at Boda prospect is subvertical. • True intervals are likely to be ~50% of downhole lengths |
| 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. |
• Plans showing geology with drill collars are included in the body of the announcement. |
| 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. |
• Comprehensive reporting has been undertaken with all holes listed in the included table. |
| 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. |
• No other exploration data is available to assist in interpretation. |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). |
• It is recommended that further drilling at Boda prospect to define its resource potential. Other drilling work targeting the IP anomalies will be undertaken within the licence. |
| • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive |
• See figures included in the announcement. |
