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 echelon 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 26 metres grading 4.36g/t Au from 112 metres;
incl 3.3 metres grading 22.8g/t Au from 112.7 metres.
MCLUG012D 10.7 metres grading 2.09g/t Au from 105 metres.
MCLUG011D 8 metres grading 2.33g/t Au from 113 metres;
incl 0.8 metres grading 14.4g/t Au from 118 metres.
MCLUG007D 5.2 metres grading 1.62g/t Au from 99.9 metres;
and 6.1 metres grading 2.65g/t Au from 113 metres.
MCLUG006D 7.8 metres grading 3.46g/t Au from 120 metres;
incl 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:
MCLUG012D 10 metres grading 1.31g/t Au from 284 metres;
and 3.7 metres grading 1.66g/t Au from 314.1 metres.
MCLUG010D 0.5 metres grading 38.9g/t Au from 332.5 metres.
MCLUG009D 8 metres grading 1.85g/t Au from 301 metres.
MCLUG007D 8 metres grading 2.67g/t Au from 293.2 metres;
incl 3.1 metres grading 4.52g/t Au from 298.1 metres;
and 8 metres grading 4.38g/t Au from 320 metres;
incl 2 metres grading 12.6g/t Au from 320 metres.
MCLUG005D 10 metres grading 1.54g/t Au from 276 metres.
Further drilling is planned to test both the Eastern and Western Andesite hosts at McLeans and to include the discovered Western Andesite into the McLeans Resource Estimation.
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. The drilling confirmed multiple wide, high-grade gold intercepts within the 30 m thick monzodiorite. The results received are a large part of the current drill program within the Western Monzodiorite and include best intercepts of:
ROSGT001D 9.3 metres grading 3.88 g/t Au from 157.9 metres;
incl 1.1 metres grading 10.5 g/t Au from 157.9 metres;

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 Bjorkdal underground gold mine northwest of Skelleftea 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.

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.
