Tomingley Drilling Discovers New Mineralisation at McLeans

  • Underground core drilling at Tomingley is focused on defining extensions to resources as well as improving confidence of Inferred Resources at McLeans and the Western Monzodiorite domain at Roswell. Both McLeans and the Western Monzodiorite are immediately adjacent to existing underground infrastructure.   
  • Underground drilling comprising of 9 diamond holes for a total of 3,247 metres was completed to improve the confidence of the Inferred Resource at McLeans. This drilling discovered a second andesite with significant gold mineralisation, located approximately 150m to the west of the current resource. Significant gold intercepts hosted by the western andesite include:

PERTH, Australia, Nov. 02, 2025 (GLOBE NEWSWIRE) -- Alkane Resources Limited (ASX:ALK; TSX:ALK; OTCQX:ALKEF) (‘Alkane’ or ‘the Company’) is pleased to announce the latest results for underground expansion and pre-mine grade control drilling around the existing resources at the Company’s Tomingley Gold Operations (‘Tomingley’) in Central New South Wales.

Alkane Managing Director Nic Earner said: “Most of Tomingley’s deposits are open at depth and along strike. This drilling further demonstrates not only the significant resource expansion potential across the mine site but the potential to discover other deposits.

“Our underground and surface drill programs throughout Tomingley continue. We look forward to continuing to add further resources and mine life.”

Tomingley

Alkane Resources Ltd 100%

Tomingley is an open pit and underground mining development with a 1Mtpa processing facility in operation since 2014. The development is located near the village of Tomingley, approximately 50 kilometres southwest of Dubbo in Central West New South Wales. Tomingley Gold Operations Pty Ltd is a wholly owned subsidiary of Alkane.

Development at Tomingley has been based on the Wyoming One, Wyoming Three, Caloma, Caloma Two and Roswell gold deposits. To date, mining occurred underground at Wyoming One, Caloma, Caloma Two and Roswell deposits. Roswell stope ore production came on stream in April 2024 (See ASX Announcement dated 22 April 2024 and titled ‘Production Ore Extraction Commences at Roswell’) via an approximately 3 km decline from the Wyoming One open cut.

The Tomingley deposits are located within a tightly folded Ordovician volcano-sedimentary sequence that has been altered to a sericite-carbonate-albite-quartz-pyrite-arsenopyrite assemblage that is typical of orogenic lode-style gold deposits. Mineralised fluids are interpreted to have been focused by differential strain in and around andesitic volcanics due to the rheological competency contrast between the volcanics and the bounding volcaniclastic sediments. The brittle nature of the volcanics often leads to the development of shear-hosted sheeted quartz vein and breccia deposits within and adjacent to the andesitic bodies. Separately, thin carbonaceous mudstone strata appear to have been a focus for shearing and a chemical trap for gold.

Since underground mining commenced in 2018, extensive underground drilling has been employed to define ore reserves for extraction and maintain exploration to define additional resources. The most recent Reserves and Resources were summarised in the ASX Announcement dated 15 October 2025 and titled ‘NSW Resources and Reserves Statements FY25’.

The exploration focus at Tomingley is to define additional underground resources that lie outside the existing Resources and Reserves for the operation.

McLeans

The Inferred Resource at McLeans was estimated at 0.87 million tonnes grading 2.51g/t gold for 70,000oz (See ASX Announcement dated 2 May 2022 and titled ‘Roswell Mineral Resource up 37%’). The deposit is primarily hosted by one ‘brittle’ andesite with similar texture and geochemistry as the andesite that is host to most of the mineralisation at the Roswell deposit. The host andesite begins approximately 130m below the surface, is approximately 250m in strike length and remains open at depth. The andesite averages a thickness of 60m but thins to 25m along its upper and northern margins forming a ‘keel’. The mineralisation was interpreted to form three subvertical en échelon sheeted lodes. With high-grade ore shoots focused along the ‘keel’ that remains open at depth along the northern edge of the andesite.

In September, an underground drilling program comprising of 9 holes for a total of 3,247 metres was completed to improve the confidence at the McLeans Inferred Resource by infilling the drilling pattern to 40m x 60m. This drilling has discovered a second ‘western’ andesite with significant gold mineralisation that is located 150 metres west of the current McLeans resource estimation. Significant intercepts hosted by the Western Andesite include:

MCLUG013D
incl
  26 metres grading 4.36g/t Au from 112 metres;
3.3 metres grading 22.8g/t Au from 112.7 metres.

MCLUG006D
incl
  7.8 metres grading 3.46g/t Au from 120 metres;
1.0 metres grading 10.1g/t Au from 126 metres.

The nominal drilling pattern was reduced from 80m x 80m that the Inferred Resource was based on to 40m  x 60m to help improve the confidence in the estimation at McLeans. Significant intercepts into the Eastern Andesite and the Inferred Resource include:

Roswell

A significant portion of the Roswell underground Inferred Resources (408 kt grading 1.9 g/t Au see ASX Announcement dated 15 October 2025 and titled ‘NSW Resources and Reserves Statement FY25’) is hosted in the Western Monzodiorite domain. An intensive underground diamond core drilling program targeting the Western Monzodiorite resource and its open extensions is in progress at Roswell. The drilling will improve the confidence of the Mineral Resource Estimation (MRE) and provide a basis for conversion to Ore Reserves.

Results have been received from 89 holes totalling 18,064 metres that are focused within the mid-portion of the monzodiorite domain infilling existing drilling to a nominal 15m x 20m grid spacing for the purpose of converting to an Indicated Resource.

ABOUT ALKANE alkres.com ASX:ALK | TSX: ALK | OTCQX: ALKEF

Alkane Resources (ASX:ALK; TSX:ALK; OTCQX:ALKEF) is an Australia-based gold and antimony producer with a portfolio of three operating mines across Australia and Sweden. The Company has a strong balance sheet and is positioned for further growth.

Alkane’s wholly owned producing assets are the Tomingley open pit and underground gold mine southwest of Dubbo in Central West New South Wales, the Costerfield gold and antimony underground mining operation northeast of Heathcote in Central Victoria, and the Björkdal underground gold mine northwest of Skellefteå in Sweden (approximately 750km north of Stockholm). Ongoing near-mine regional exploration continues to grow resources at all three operations.

Alkane also owns the very large gold-copper porphyry Boda-Kaiser Project in Central West New South Wales and has outlined an economic development pathway in a Scoping Study. The Company has ongoing exploration within the surrounding Northern Molong Porphyry Project and is confident of further enhancing eastern Australia’s reputation as a significant gold, copper and antimony production region.

APPENDIX 1

JORC Code, 2012 Edition – Table 1 report – Roswell and McLeans October 2025
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.
Resource infill and extension drilling has been undertaken at the McLeans and Roswell Western MZD Inferred Resources as part of mine development underground drilling. This drilling was NQ2 core at Roswell and HQ2 at McLeans.

DD sample intervals were defined by site geologists during logging to honour geological boundaries with whole core sampled on intervals defined by the geologist.
  • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
Core was laid out in suitably labelled core trays. A core marker (core block) was placed at the end of each drilled run 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.
  • 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.
Diamond core sample intervals were defined by geologists during logging to honour geological boundaries and cut in half with a saw if HQ2 (at McLeans). NQ2 diamond core drilling conducted at Roswell was whole core sampled.

All samples sent to the laboratory were crushed and/or pulverised to produce a ~100g pulp for assay process.

All samples are fire assayed using a 50g charge.
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).
Diamond core holes at Roswell were drilled NQ2 and at McLeans were drilled HQ2.
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.
  • Measures taken to maximise sample recovery and ensure representative nature of the samples.
All NQ2 core was whole sampled to ensure representativity of sampling. Larger diameter HQ2 was half sampled.
  • 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.
DD - all core was laid out in core trays and 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). A brief geotechnical log was also undertaken collecting parameters such as core recovery, RQD, fracture count, and fracture type and orientation.
  • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.
All logging was qualitative with visual estimates of the various characteristics. .

DD - Core was photographed and any unsampled core is retained for reference purposes.
  • The total length and percentage of the relevant intersections logged.
All DD core samples have been geologically and geotechnically logged by qualified geologists.
Sub-sampling techniques and sample preparation









  • If core, whether cut or sawn and whether quarter, half or all core taken.
HQ2 core sawn with half core samples submitted for analysis. NQ2 core whole sampled and submitted for analysis.
  • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.
Not applicable – no ‘non core’ sub sampling techniques or sample preparation used.
  • For all sample types, the nature, quality and appropriateness of the sample preparation technique.
Samples were delivered to ALS Minerals Laboratory, Orange NSW. Crushed with 70% <2mm (ALS code CRU-31), split by riffle splitter (ALS code SPL-21), and pulverised 1000grm to 85% <75um (ALS code PUL-32). Crushers and pulverisers are washed with QAQC tests undertaken (ALS codes CRU-QC, PUL-QC).
  • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.
Internal QAQC system in place to determine accuracy and precision of assays.
  • 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.
Entire core sampling was undertaken for NQ2. Non-biased core cutting for HQ2 using an orientation line marked on the core.
  • Whether sample sizes are appropriate to the grain size of the material being sampled.
Sample sizes are industry standard and considered appropriate.
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.
Gold was determined using a 50g charge fused at approximately 1100°C with alkaline fluxes, including lead oxide. The resultant prill was dissolved in aqua regia and gold determined by flame AAS
  • 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.
Not applicable to this report or deposit as no geophysical tools, spectrometers, handheld XRF instruments were used.
  • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.
Commercially prepared Certified Reference Materials (CRM) and blanks were inserted at 1 in 50 samples. CRM’s were not identifiable to the laboratory.

Laboratory QAQC sampling includes insertion of CRM samples, internal duplicates and screen tests. This data was reported for each sample submission.
Verification of sampling and assaying





  • The verification of significant intersections by either independent or alternative company personnel.
Drill data was compiled and collated and reviewed by senior staff. External consultants do not routinely verify data until resource estimation procedures are deemed necessary
  • The use of twinned holes.
Twinned holes have not been used for this drilling.
  • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.
All drilling data at Tomingley is stored in a “Datashed” Microsoft SQL database.

All primary assay data was received from the laboratory as electronic data files which were imported into sampling database with verification procedures in place. QAQC analysis was undertaken for each laboratory report.

Digital copies of Certificates of Analysis (COA) are stored in a central database with regular (daily) backup. Original survey data is stored on site.

Data was also verified on import into mining related software.
  • Discuss any adjustment to assay data.
No assay data was adjusted.
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.
Drill holes were laid out by underground survey.

DD holes were surveyed during drilling to maintain drilling direction and then at 6m intervals on retrieval of rod string using a multi shot electronic camera.
  • Specification of the grid system used.
Drill holes laid out in MGA.
  • Quality and adequacy of topographic control.
The area is very flat. A site based digital terrain model was developed from accurate (± 0.1m) survey control by licenced surveyors.
Data spacing and distribution



  • Data spacing for reporting of Exploration Results.
Infill drilling at the Roswell Western MZD is completed on a pattern of 10m x 15m pattern when combined with exploration drill holes. Infill resource drilling at McLeans was completed on nominal 20m x 20m spacing when combined with previous exploration drill holes.

The drill hole spacing is similar to that used at the other Tomingley deposits and has been determined as sufficient.
  • 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.
The mineralisation domains tested by this drilling is classified as Inferred based on its data distribution and hosted in the same monzodiorite or andesite domain. All the new drilling intersected the monzodiorite or andesite host and their spacing and distribution will be sufficient to further inform this Inferred resource mineralisation domain.
  • Whether sample compositing has been applied.
Samples are diamond core and intervals are based on geological logging, and are simple intervals as described earlier in the table.
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.
Much care was given to attempt to intersect mineralisation at an optimal angle but location of drill drives is the major determination of intersection angle. Most holes are 80% of true thickness.
  • 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.
It is not thought that drilling direction will bias assay data.
Sample security
  • The measures taken to ensure sample security.
All samples were bagged in tied numbered calico bags, grouped into larger tied polyweave bags and transported to the laboratory in Orange by courier. Sample submission sheets were delivered with the samples and also emailed to the laboratory. All sample submissions were documented via ALS tracking system and all assays were reported via email.

Sample pulps were returned to site and were stored for an appropriate length of time (minimum 3 years).

The Company has in place protocols to ensure data security.
Audits or reviews
  • The results of any audits or reviews of sampling techniques and data.
The Company does not routinely have external consultants verify exploration data until resource estimation procedures are deemed necessary.

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 three Tomingley mining licences are held in the name of Tomingley Gold Operations Pty Ltd (TGO), a wholly owned subsidiary of Alkane Resources Ltd. The Roswell and McLeans deposits are within ML 1858.  
  • 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.
ML1684 and ML 1821 expire on 11 February 2034. ML 1858 expires on 19 July 2044.
Exploration done by other parties
  • Acknowledgment and appraisal of exploration by other parties.
All reported drilling has been completed by TGO.
Geology
  • Deposit type, geological setting and style of mineralisation.
Geological nature of the Tomingley Deposits is well documented elsewhere.

Mineralisation is associated with quartz veining and alteration focused within sub-volcanic basaltic-andesite sills and adjacent volcaniclastic sediments. The deposits appear to have formed as the result of a rheological 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.
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:
    • easting and northing of the drill hole collar
    • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar
    • dip and azimuth of the hole
    • down hole length and interception depth
    • hole 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 drill holes (detailing significant assay results of >1.3g/t Au) are reported. Exclusion of assay data from below this cut-off will not detract from the understanding of this report. All drill data has been previously reported.
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.
Reported results have been –
  • For uncut gold grades;
  • Intercepts were defined (bounded) by 1.0g/t gold outer limit and may contain some internal waste (<1.0g/t);
  • Only intervals grading ≥1.3 g/t gold are reported;
  • Grades were 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.
Exploration results are reported as length weighted average grades with internal high-grade intercepts reported separately.
  • The assumptions used for any reporting of metal equivalent values should be clearly stated.
No metal equivalents are reported.
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’).
Reported results include the drilled width and an estimate of true width.

At Roswell and McLeans the true width is approximately 80% of the drilled 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.
Cross sections and plans showing drilling with 3D geological modelling are included in the body of this 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 drill 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).
See body of announcement. Further underground drilling will be undertaken to improve resource classification from Inferred to Indicated at Roswell and McLeans. Further drilling will delineate a resource for the recently discovered western andesite at McLeans.
  • 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.
