Tomingley Gold Project (TGP)
Alkane Resources Ltd 100%
The Tomingley Gold Project (TGP) covers an area of approximately 440 km[2 ] stretching 60 km north-south along the Newell Highway from Tomingley in the north, through Peak Hill and almost to Parkes in the south. The TGP contains Alkane’s currently operating Tomingley Gold Operations (TGO), an open pit mine and underground operation with a 1 Mtpa processing facility.
Over the past four years Alkane has conducted an extensive regional exploration program that led to the definition of Mineral Resources at the Roswell and San Antonio deposits (ASX Announcement 2 May 2022 and ASX Announcement 16 February 2021), separate to the established resources and reserves at Tomingley. Roswell and San Antonio form part of the Tomingley Gold Extension Project (TGEP).
Alkane has completed an exploration drive from the Wyoming One open cut to Roswell, a distance of about 3km. The TGEP was approved by the New South Wales Minister for Planning (ASX Announcement 22 February 2023) and the Company is progressing its Environmental Protection Licence and Mining Lease applications.
Regional exploration drilling recommenced in the region in early 2023 focusing on McLeans, Roswell North, Plains, El Paso and Allendale prospects that are all located within 7 km of the TGO processing facility. Drilling was also conducted from the underground exploration drive on the McLeans prospect for the purposes of estimating an initial Inferred Mineral Resource.
As part of the recent exploration drilling, assay results were received from 142 air-core (AC) drill holes for a total of 15,321 metres; 18 reverse circulation (RC) drill holes for a total of 5,212 metres; and 4 diamond core (DD) for a total of 1,481 metres of core.
The exploration undertaken:
-
Targeted the strike of the andesite hosting the mineralisation at the McLeans Prospect and infilling previously intersected mineralisation with 5 RC holes and 4 underground DD holes;
-
Targeted a northern extension to the Roswell Deposit with 1 RC hole;
-
Tested the strike extensions, the width and depth of mineralisation at the Plains Prospect located 1 km southeast of the Roswell Deposit with 47 AC holes and 6 RC holes;
-
Tested around the mineralised Roswell-type andesite in the southern section of the El Paso prospect with 6 RC holes; and
-
Tested the covered Narromine Igneous Complex west of the Parkes Thrust for copper-gold mineralisation with 95 AC holes at Ellendale.

McLeans Prospect
McLeans Prospect is located 500 metres northeast of the Roswell Deposit and adjacent to the exploration drive from Wyoming One. In 2021, a deep RC drill hole (MCP092) discovered the McLeans andesite (correlates with the andesites that host the gold resources at the Roswell and San Antonio deposits) approximately 100 metres below surface, intersecting 34m @ 1.80g/t Au from 178m and 19m @ 1.25g/t Au from 242m (ASX Announcement 16 September 2021). The gold mineralisation is associated with either sheeted quartz veins or as pyrite-silica cemented breccias, hosted within and along the contacts of the andesite host.
The McLeans host andesite strike length was recently tested by five step-out RC drill holes for a total of 1,886 metres. The drilling intersected weakly mineralised volcaniclastic sediments, defining the host rock has a maximum strike length of 300 metres. Four underground diamond core drill holes for a total of 1,481 metres, were designed to infill the previous drilling of the mineralised andesite. Significant gold intercepts from the underground drilling include:
5.1 metres grading 1.45g/t Au from 126.4 metres; incl 2.5 metres grading 2.62g/t Au from 129 metres; and 11.3 metres grading 3.72g/t Au from 310 metres; incl 1 metre grading 10.5g/t Au from 316 metres; also 0.7 metres grading 14.8g/t Au from 319.3 metres. MCLUG003D 5.8 metres grading 0.88g/t Au from 275.9 metres; 6.1 metres grading 0.87g/t Au from 303.4 metres; incl 1.2 metres grading 2.88g/t Au from 308.3 metres. MCLUG001D 7.2 metres grading 0.91g/t Au from 305.1 metres; incl 1.3 metres grading 2.66g/t Au from 305.1 metres.
Diamond core drill hole MCLUG004D intersected the northern end of the andesite where it thins from 70 metres to 20 metres in width. The andesite also thins at its upper contact. Stockwork high grade gold mineralisation appears to favour the thinned northern and upper contact of the andesite forming as carapace-focused mineralisation. This zone is open at depth along the northern contact. A new, ~20metre-thick andesite unit with minor Au mineralisation was intersected from around 100 metres downhole (east) of the underground drilling platform. This mineralised andesite is open to the north, south and at depth. A maiden underground Inferred Mineral Resource estimation for McLeans is underway and is expected to be completed in the current calendar year.
El Paso Prospect
Exploration drilling focused on the southern and less covered (under 30 metres) section of the El Paso Prospect, where significant gold mineralisation has been intersected previously (EPP012 – 12m @ 4.99g/t Au from 108 m, 21m @ 2.38g/t Au from 141m, and 6m @ 10.65g/t Au from 168m – ASX Announcement 17 May 2019). This mineralisation is hosted in an andesite similar in nature to the San Antonio volcanics that host the gold resource 1 km to the north.
Six RC drill holes for a total of 1,146 metres were completed at El Paso with the sandy alluvial overburden continuing to make the drilling conditions difficult and only four were completed to target depth. Significant gold mineralisation intersected by three of the RC drill holes include intercepts of:
EPP046 42 metres grading 1.68g/t Au from 42 metres; incl 6 metres grading 2.98g/t Au from 51 metres;

| also | 3 | metres grading | 4.66g/t Au from | 69 metres; |
|---|---|---|---|---|
| incl | 3 | metres grading | 3.21g/t Au from | 81 metres. |
| EPP047 | 30 | metres grading | 0.56g/t Au from | 267 metres; |
| incl | 6 | metres grading | 2.00g/t Au from | 285 metres. |
| EPP049 | 9 | metres grading | 2.30g/t Au from | 108 metres. |
The strong gold mineralisation is hosted in andesite that strikes northeast, dips southeast and is controlled within southeast plunging shoots. High-resolution airborne magnetics is planned to improve definition of the andesite hosts and significant structures at the prospect. Drilling targets generated by the survey in addition to follow up drilling of targets generated by these recent results are proposed for Q1 2024.
Plains Prospect
Further air-core drilling was conducted to test the strike extents of the previously defined zone of anomalous gold mineralisation with approximate dimensions of 500 metres x 200 metres, that strikes northeast associated with a magnetic low along the western margin of a basaltic-andesite body. Two 150 metre-spaced air-core drill hole traverses were completed to extend previous traverses east across the northeast-trending zone of mineralisation. Two 100 metre-spaced traverses south of the gold zone were also completed transecting across the 500 metre-thick basaltic-andesite. A total of 47 drill holes for 3,886 metres were completed intersecting significant gold results of:
RWAC477 3 metres grading 2.08g/t Au from 90 metres. 6 metres grading 0.83g/t Au from 78 metres.
Six RC drill holes totalling 1,732 metres further tested the northeast striking mineralisation and its depth potential. The mineralisation forms as sheeted quartz-arsenopyrite-pyrite veins hosted in predominantly phyllic-altered basaltic andesite. Significant gold mineralisation from the drilling includes:
| RWRC477 | 8 | metres grading 0.97g/t Au from 134 metres; |
|---|---|---|
| incl | 2 | metres grading 2.02g/t Au from 136 metres. |
| RWRC478 | 4 | metres grading 1.54g/t Au from 183 metres; |
| incl | 1 | metre grading 5.54g/t Au from 183 metres. |
| RWRC479 | 6 | metres grading 0.84g/t Au from 164 metres; |
| incl | 3 | metres grading 1.48g/t Au from 167 metres. |
The Plains Prospect is located approximately 1 km southeast of the Roswell Deposit in a structurally favourable corridor, sharing the same northwest trending structural zone that hosts the Roswell gold deposit. Further drilling is planned for early 2024.
Allendale (Gold-Copper) Prospect
The Allendale prospect area lies approximately 5 km north-west of Tomingley on the western side of the Parkes Thrust. The Parkes Thrust is a principal regional structure that separates the largely undeformed andesitic volcanics (Narromine Igneous Complex) similar to those that host the Northparkes copper-gold porphyry deposits to the west from the highly deformed and faulted volcanics and volcaniclastics to the east that are host to the orogenic gold mineralisation at Tomingley. The entire prospect area is covered by 30 - 80 metres of alluvial quartz-rich sands and clays of the Gunnedah Basin and any previous exploration is limited to air-core drilling with three holes diamond core tailed.

Ninety-five air-core drill holes for a total of 11,435 metres were drilled at 100 metre collar spacing along seven traverses spaced nominally 1 kilometre apart. The drilling was generally angled west along the traverses and drilled to refusal at fresh bedrock. Bottom of hole litho-geochemistry sampling was conducted to map the Ordovician basement and the weathered bedrock beneath the cover was sampled as 3-metre composites for copper and gold. Numerous zones of anomalous gold and copper intersected by the drilling were mostly hosted in volcanics shown on the following plan. Significant gold and/or copper results include:
| clude: | ||
|---|---|---|
| ALAC090 | 33 | metres grading 0.08% Cu, 0.05g/t Au from 33 metres; |
| incl | 3 | metres grading 0.45g/t Au, 0.06% Cu from 54 metres. |
| ALAC092 | 12 | metres grading 0.52g/t Au, 0.02% Cu from 57 metres. |
| ALAC093 | 3 | metres grading 0.60g/t Au from 57 metres. |
| ALAC132 | 1 | metre grading 0.15% Cu from 131 metres to end of hole. |
| ALAC147 | 21 | metres grading 0.11% Cu from 93 metres. |
| ALAC176 | 13 | metres grading 0.99g/t Au, 0.03% Cu from 127 metres to end of hole; |
| incl | 3 | metres grading 3.03g/t Au, 0.02% Cu from 133 metres. |
Drilling of the northernmost traverse and 300 metres south of the Exploration Licence 6085 boundary intersected significant gold mineralisation with drill hole ALAC176 (13 metres grading 0.99g/t Au, 0.03% Cu from 127 metres to end of hole, including 3 metres grading 3.03g/t Au, 0.02% Cu from 133 metres). The mineralisation is associated with goethite-stained quartz veining hosted in a weathered andesite and the drill hole terminated in 0.19g/t Au.
The ground immediately north of EL6085 was recently pegged by Alkane Resources (ELA6625) and covers an additional 3 km strike length of these host volcanics, that has previously undergone only limited drilling. An airborne gravity survey is planned for November 2023 over Allendale and the Narromine Igneous Complex. Infill air-core drilling is planned for 2024.

ABOUT ALKANE ‐ www.alkane.com.au ‐ ASX: ALK
Alkane Resources intends to grow to become one of Australia’s multi-mine gold and copper producers.
The Company’s current gold production is from the Tomingley Gold Operations in Central West New South Wales, where it has been operating since 2014 and is currently expediting a development pathway to extend the mine’s life beyond 2030.
Alkane has an enviable exploration track record and controls several highly prospective gold and copper tenements. Its most advanced exploration projects are in the tenement area between Tomingley and Peak Hill, which have the potential to provide additional ore for Tomingley’s operations.
Alkane’s exploration success includes the landmark porphyry gold-copper mineralisation discovery at Boda in 2019. With drilling ongoing adjacent to the initial resources identified at Boda and Kaiser, Alkane is confident of further consolidating Central West New South Wales’ reputation as a significant gold production region.
Alkane’s gold interests extend throughout Australia, with strategic investments in other gold exploration and aspiring mining companies, including ~9.0% of Calidus Resources (ASX: CAI).

JORC Code, 2012 Edition – Table 1 TOMINGLEY GOLD PROJECT – Regional Exploration July 2023
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 (DD) was undertaken by HMR Drilling Services 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 • Air-core (AC) drilling was undertaken by Drillit Pty Ltd • RC and AC 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 and AC 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 ≥0.20 g/t Au are resplit using a cone splitter on the RC rig or a riffle splitter for AC sample 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 either aqua regia or 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 • Diamond drilling was HQ wireline bit producing 63.5mm diameter sized orientated core. • Air-core (AC) drilling using 89mm rods and bit to refusal. |
| 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. • RC and AC 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 • 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. • A high capacity AC rig was used to maximise penetration through the clays to refusal on fresh bedrock. Drill cyclone was cleaned 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 |
|

• 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 ≥0.20 g/t Au are re-split using a cone splitter on the RC rig during the time of drilling or re-split using a riffle splitter for AC composites and re-submitted to the laboratory for re-assay. • Laboratory Preparation – the entire sample (~3kg) is dried and pulverised in an LM5 (or equivalent) to ≥85% passing 75µm. Bulk rejects for all samples are discarded. A pulp sample (±100g) is stored for future reference. |

• Significant exploration has been completed in the area by Alkane since 2001 and the Tomingley Gold Mine was commissioned in 2014. • Minor work was completed by previous companies in EL5675 area covered by this announcement but many holes did not penetrate the cover sequence. • Work completed within EL6085 at the Allendale Prospect can be summarised as: Climax (in JV with Newcrest, Transit, MPI Gold) (1989-2003) – Tenement-wide heli- magnetics, MMI soils (no anomalism as deep cover was prohibitive); 70x air-core drill holes for 7,458m over magnetic targets intersecting broad zones of Au-Cu anomalism. Follow up 3x diamond core tails off air-core pre-collars for 764m with a petrology study. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• Mineralisation at Tomingley is associated with quartz veining and alteration focused within porphyritic sub-volcanic andesite sills and adjacent volcaniclastic sediments. The deposits appear to have formed as the result of a competency contrast between the porphyritic sub-volcanic sills and the surrounding volcaniclastic sediments, with the sills showing brittle fracture and the sediments ductile deformation and have many similarities to well documented orogenic - lode-style gold deposits. • Geological nature of the Tomingley Deposits is well documented elsewhere. • Geological nature of Peak Hill is well documented elsewhere. • Geological nature of Glen Isla is fine grained low-sulfidation epithermal Au mineralisation that was discovered in Middle Devonian continental felsic volcanic sequences (Dulladery Volcanics) in the Young Zone. The gold prospective Dulladerry Volcanics host a number of low sulfidation epithermal occurrences including the Mt Aubrey gold deposit (120,000 t @ 3.3 g/t Au) and are broadly similar in age (~370Ma) to dates published (~350 - 360 Ma) for volcanic units that host well known Drummond Basin epithermal Au deposits in north Queensland. DulladerryVolcanics include flow banded rhyolites andquartz |

| 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 |
| • 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 RC and DD drill holes have been reported in this announcement. • Only AC drill holes with significant assays of ≥0.2g/t Au have been reported for Tomingley and assays of >0.1g/t Au and/or >0.05% Cu for Allendale. Impractical to list all holes completed. |
|
| 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 (>0.2g/t Au) are calculated using a broad lower cut of 0.2g/t Au although grades lower than this may be present internally (internal dilution). • 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’). |
• The mineralisation is structurally complex and the majority of drilling is reconnaissance in nature. Down hole lengths reported – true widths estimated to be 60% of the down hole lengths at El Paso, Roswell North and Allendale. At Plains Prospect it is early stage exploration but true width is estimated at 80%. Underground diamond drilling at McLeans intercepts are estimates as 90% - 100% true 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. |
• 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 DD and RC 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 considered meaningful for reporting. |
| 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 is undertaken at these prospects to continue to define targets. McLeans has an appropriate drilling density for the purpose of a maiden resource estimation. |
| • 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. |
