Greatland Resources Limited reported strong progress across its December 2025 quarter exploration programme, drilling 54,204 metres at Telfer and lifting total metres drilled in the first half of FY26 to a record 106,766.
Results from the West Dome Underground project were particularly encouraging, including an outstanding intercept of 55.3 metres grading 7.4 g/t gold and 0.43% copper, the highest-grade result recorded at the project to date. The company is targeting a maiden Mineral Resource estimate for West Dome Underground in the March 2026 quarter.
Ongoing resource growth and conversion drilling at West Dome Open Pit and Main Dome Underground continue to improve geological confidence. More than 100,000 metres of new drilling will underpin the forthcoming Telfer Mineral Resource update.
Regional exploration also delivered positive results, highlighted by an intercept of 8 metres at 1.30 g/t gold at the Teague prospect, supporting the broader exploration upside across the Telfer tenure.

Greatland Managing Director, Shaun Day, commented:
“Our record 240,000m annual drilling program at Telfer has continued to deliver very promising results in the December quarter, which strongly support the potential for multi-year Telfer life of mine extension from both open pit and underground opportunities.
“The high-grade West Dome Underground project is particularly exciting, returning the highest gram-metre intercept to date of 55.3m at 7.4 g/t gold and 0.43 % copper (411 gram-metres gold). Encouragingly, this result is the southern most assay returned to date, and the mineral system is increasing in size towards the south which remains open. Three diamond drill rigs are now operating at the project and a maiden Mineral Resource estimate is targeted in the March 2026 quarter.
“Resource growth and conversion drilling in the West Dome Open Pit and Main Dome Underground continue to enhance our geological confidence in near term mining areas and longer-term extension opportunities. In total, over 100,000 metres of new resource growth drilling will inform our next Telfer Mineral Resource update in the March 2026 quarter.
“The quarter’s regional exploration results are encouraging, both in the Paterson and at our Ernest Giles project, an Archean greenstone in the Yilgarn region.”
Overview
Greatland Resources Limited (Greatland) is pleased to provide this update on resource development and exploration activities.
Telfer Resource Development
Greatland remains on track to complete the largest annual drilling program in Telfer’s operating history, with ~240,000 metres total drilling planned in FY26, comprising ~150,000m of resource growth drilling and ~90,000m of resource conversion drilling.
First half (June to December 2025) drilling of 106,766m has now been completed, in line with the planned delivery schedule.
Figure 1: Telfer historic and planned FY26 drilling
The objective of the planned drilling is expansion and conversion of Telfer Mineral Resources to support targeted further multi-year mine life extensions. Three key extension opportunities are presently targeted, the West Dome Open Pit (WDO), Main Dome Underground (MDU) and West Dome Underground (WDU).
Figure 2: Telfer planned Resource Development drilling by area
A total of 54,204m was drilled during the quarter, comprising:
§ Conversion: 565 holes for 19,183m; and
§ Growth: 190 holes for 34,863m.
A fifth underground diamond drill (DD) rig was mobilised during the quarter, and the decision has been made to add a sixth underground DD rig based on the continued success in the WDU drilling program. The sixth underground rig is expected to arrive in February 2026 to enable testing of the expanse of the WDU mineralisation (extension drilling).
Three reverse circulation (RC) rigs continued drilling throughout the quarter with a relatively even split between growth and conversion drilling. Conversion drilling in FY26 H1 has now provided increased geological confidence across all active mining areas, allowing increased growth drilling focus for the remainder of FY26.
West Dome Open Pit (WDO)
Drilling for the December quarter remained focused on two priority cutback opportunities:
§ Stage 7 Extension: Extension of the existing Stage 7 cutback towards the north (refer Figure 3), which is expected to provide Telfer’s baseload ore feed for FY27 and FY28.
§ Stage 2 Extension: Extension of the current Stage 2 towards the south, east and west. The area being targeted with drilling is substantial and has the potential to support multi-year extension of the Telfer open pit mine life beyond FY28.
Stage 7 Extension drilling was completed during the quarter, with drill capacity shifting to predominately concentrate on the southern Stage 2 Extension which will remain a focus for much of the March 2026 quarter.
Figure 3: West Dome Open Pit – December 2025 Quarter (Q2 FY2026) Drilling
Drilling in the West Dome continues to increase our confidence in the geological model that underpins the Mineral Resource, with a combination of reef hosted and wide stockwork domains intercept to date.
The following significant results were returned during the quarter, with the full list of results in Table 1.
Stage 7 Extension
A total of 28 resource growth holes for 5,857 metres was completed in the quarter, with the following significant results:
§ 35m @ 4.8 g/t Au & 0.30 % Cu (167 gm) from 273m (WR28748)
§ 45m @ 0.9 g/t Au & 0.07 % Cu (41 gm) from 147m (WR39551)
§ 41m @ 1.0 g/t Au & 0.02 % Cu (41 gm) from 121m (WR39552)
§ 42m @ 0.8 g/t Au & 0.21 % Cu (35 gm) from 159m (WR39219)
§ 36m @ 1.0 g/t Au & 0.24 % Cu (36 gm) from 166m (WR40079)
§ 20m @ 1.6 g/t Au & 0.07 % Cu (24 gm) from 58m (WR39554)
§ 42m @ 0.6 g/t Au & 0.02 % Cu (25 gm) from 168m (WR40737)
All results have been received and the Mineral Resource update is in progress.
Stage 2 Extension
A total of 63 resource growth holes for 14,804 metres was completed during the quarter, with the following significant results:
§ 22m @ 2.9 g/t Au & 0.33 % Cu (65 gm) from 168m (WR24227)
§ 49m @ 0.9 g/t Au & 0.09 % Cu (47 gm) from 10m (WR27230)
§ 38m @ 1.1 g/t Au & 0.27 % Cu (42 gm) from 146m (WR24226)
§ 11m @ 3.2 g/t Au & 0.10 % Cu (36 gm) from 403m (WR25707)
§ 38m @ 0.6 g/t Au & 0.07 % Cu (24 gm) from 28m (WR27595)
§ 21m @ 0.9 g/t Au & 0.06 % Cu (20 gm) from 58m (WR33156)
With the completion of most of the growth drilling in the active mining areas during the December quarter, drilling will now shift to testing from both the eastern and western sides of the Stage 2 southern extension.
Main Dome Underground (MDU)
The first half of FY26 drilling campaign in the MDU has been focused on near term extension opportunities, and has successfully confirmed multiple near mine extensions such as A Reef, Tarkin (LLU), Rey extensions and the Eastern Stockwork Corridor (ESC) that have been drilled to a mine ready status and delivered to the operations team.
The focus of the second half of FY26 drilling is longer term growth opportunities, such as the ESC extensions, VSC, Kylo and A Reef North, which have the potential to provide significant mine life extension and are all adjacent to the existing underground infrastructure.
December quarter drilling in the MDU comprised 86 holes for 7,606 metres focused on the A Reef & ESC, with resource conversion and resource growth drilling at the Kylo target completed during the quarter.
Following the September quarter’s impressive results at Kylo, additional results were received in the December quarter (Figure 4) confirming the presence of significant mineralisation. Drilling has delineated both narrow high grade reef style and broader stockwork style mineralisation, with the technical review underway to direct future drilling and extraction options.
The following significant results were received from Kylo drilling during the quarter:
§ 17m @ 3.1 g/t Au & 0.09 % Cu (60 gm) from 28m (MUC4540093)
§ 4.0m @ 8.9 g/t Au & 0.59 % Cu (36 gm) from 34m (MUC4540090)
§ 7.7m @ 2.7 g/t Au & 0.38 % Cu (21 gm) from 26.3m (MUC4540094)
§ 22.1m @ 1.8 g/t Au & 0.31 % Cu (39 gm) from 28m (MUC4540096)
§ 49.8m @ 1.2 g/t Au & 0.07 % Cu (60 gm) from 49m (MUC4540086)

West Dome Underground (WDU)
Greatland’s announcement on 27 November 2025 “West Dome Underground Project Update” included assay results from a further 9 new holes that were received prior to that announcement.
Increasing drill density has improved understanding of the WDU, with three mineralised domains now confirmed: a broad sub-vertical Western Stockwork Corridor (WSC), flanked by the extensive Western Limb and Eastern Limb high grade shoots hosted within the Lower Limey Unit (LLU), an important geological horizon for gold-copper mineralisation at Telfer.
Western Stockwork Corridor (WSC)
The WSC mineralisation is located within the hinge of the WDU fold (Figure 5) and consists of a broad zone of concordant and discordant stockwork/sheeted and breccia veins, containing chalcopyrite, pyrite, white & pink dolomite, quartz and galena. There is also a notable overprinting of albite alteration.
The potential of this domain was first identified during the maiden underground drilling campaign, which although focused on the high-grade Western Limb also intercepted several broad zones of stockwork mineralisation within the hinge of the fold.
Recent drilling to the south (Figure 5) has return multiple intercepts of broad higher-grade mineralisation within the WSC during the quarter, with the following significant results returned during the quarter:
§ 55.3m @ 7.4 g/t Au & 0.43 % Cu (411 gm) from 426.7m (WUC4550104)
§ 29m @ 2.0 g/t Au & 0.01 % Cu from (58 gm) 405m (WUC4550102)
§ 56.6m @ 2.2 g/t Au & 1.26% Cu (127gm) from 337m (WUC4550083) – previously announced2
§ 82.2 @ 1.9 g/t Au & 0.31% Cu (156gm) from 360.7m (WUC4550092) – previously announced2
§ 66.5m @ 1.18 g/t Au & 0.16% Cu (78gm) from 334m (WUC4550085) – previously announced2
§ 24.0m @ 1.18 g/t Au & 0.10% Cu (28gm) from 309m (WUC4550081) – previously announced2
The drilling to date confirms continuous WSC mineralisation over 700m of strike, averaging approximately 40m wide (true width) x 150m dip extent (height), and remains open along strike, and up and down dip. These recent results indicate higher grade and increased width to the south of the Phase 1 drilling.
The WSC is considered comparable to the Vertical Stockwork Corridor or ‘VSC’ domain that was one of the dominant domains targeted by the Sub-Level Cave (SLC) at the Telfer Main Dome Underground from 2008 to 2019 (mining approximately 5Mtpa on average) and is a key extension opportunity currently under assessment.
Western Limb
The Western Limb of LLU mineralisation has returned some of the highest grade WDU results to date and this continues to be the case. Mineralisation has been confirmed over 700m in strike, averaging 10m wide and over 100m down dip to date, and remains open to the north and south.
The following significant results were returned during the quarter:
§ 27.0m @ 9.3 g/t Au & 0.15 % Cu (250 gm) from 495m (WUC4550104)
§ 27.1m @ 3.2 g/t Au & 0.95 % Cu (88 gm) from 323m (WUC4550068)
§ 15.8m @ 5.0 g/t Au & 0.23 % Cu (79 gm) from 332m (WUC4550087)
§ 28.9m @ 2.4g/t Au & 0.24% Cu (68 gm) from 430m (WUC4550105)
§ 30.1m @ 1.6 g/t Au & 0.48 % Cu (49 gm) from 368m (WUC4550084)
§ 28m @ 1.8 g/t Au & 0.34% Cu (52gm) from 366m (WUC4550081) – previously announced2
§ 5.5m @ 3.6 g/t Au & 0.29% Cu (20gm) from 389m (WUC4550083) – previously announced2
§ 7.15m @ 2.3 g/t Au & 0.13% Cu (17gm) from 416m (WUC4550085) – previously announced2
§ 6.84m @ 2.28g/t Au & 0.25% Cu (16gm) from 447m (WUC4550092) – previously announced2
Eastern Limb
The Eastern Limb mineralisation is hosted with the same LLU unit that has hosted the Western Limb and has been defined over 500m in strike, 100m dip extents and averaging 10m true width (Figure 5).
Increased mineralisation is now being identified in the Eastern Limb, with recent results returning similar grades to those seen in the Western Limb.
The following significant results were returned during the quarter:
§ 50.2m @ 2.8 g/t Au & 0.36 % Cu (140 gm) from 262.53m (WUC4550105)
§ 8.5m @ 3.0 g/t Au & 0.16 % Cu (26 gm) from 213.85m (WUC4550104)
§ 6.6m @ 1.9 g/t Au & 0.39% Cu (12gm) from 154m (WUC4550083) – previously announced2
§ 3.85m @ 4.1 g/t Au & 0.38% Cu (16gm) from 168m (WUC4550092) – previously announced2
§ 4.75m @ 1.7 g/t Au & 0.13% Cu (8gm) from 155m (WUC4550081) – previously announced2
§ 12.6m @ 1.4 g/t Au & 0.13% Cu (17.5gm) from 209.4m (WUC4550102) – previously announced2
Note (2): Result reported in the announcement “West Dome Underground Project Update” on 27 November 2025.

Regional Exploration
Greatland holds a significant portfolio of precious and base metals focused exploration and development projects in Western Australia, the focus of which is the Paterson region surrounding Telfer and Havieron.
Figure 7: Paterson region projects
In H1 FY26 Greatland advanced extension drilling at several known satellite deposits on mining leases, within trucking distance of the Telfer processing plant, and considers them to have potential to provide ore feed to Telfer.
The main targets tested to date are the South-East Hub, Thomsons deposit 16km NE of the mill, Camp Dome deposit, ~16km north of the mill and the O’Callaghans tungsten-copper polymetallic skarn deposit (Figure 7).
Work has also been completed targeting prospects within the Paterson South project (the subject of a farm-in and joint venture arrangement between Greatland Paterson South Pty Ltd and Rio Tinto Exploration Pty Limited (RTX), under which Greatland is earning up to a 75% interest).
South-East Hub (SE Hub)
The SE Hub is located approximately 25km south-east of the Telfer Mine Site and hosts a cluster of three known deposits (Big Tree, Dolphy and Ironclad) that were historically reported as Mineral Resources by Telfer’s previous owner Newcrest Mining Limited, but have not been declared as Mineral Resources by Greatland until adequate technical evaluation is conducted.
Drilling during the quarter has focused on testing for extensions down dip and along strike of the Big Tree deposit (Figure 8). Three of six planned diamond holes have been completed and one is in progress, for a total of 1,197m drilling. Assay results have been received for two holes and partial results for one.
Encouragingly, two holes drilled to the northeast and along strike of the historic resource intersected shallow mineralisation down dip from historic drilling. The program is planned to recommence in the June 2026 quarter.
Highlights to date include:
§ 5.38m @ 1.60g/t Au from 110.62m, including 0.25m @ 33.2g/t Au from 112.65m (BT25DD001)
§ 25m @ 0.24g/t Au from 124m (BT25DD002)

Figure 10: Oblique section B showing partial results from hole BT25DD002 and historic drilling.
Thomsons
Thomsons is an historic deposit located approximately 14km northwest of Telfer on the western limb of a tight overturned anticlinal structure with mineralisation hosted in reef and stockworks analogous to Telfer Main and West Dome deposits. In September 2025, Greatland completed a seven hole drill program aimed at testing for Telfer style stacked reef and stockwork mineralisation beneath and along strike of shallow (<100m) historical mineralisation.
Assay results for the remaining three drillholes of the program have been received. The program has demonstrated potential for additional shallow mineralisation along strike and down dip of historic drilling and has identified a new high-grade east west oriented vein set that remains open along strike and down dip. The potential for stacked reef mineralisation at depth has been downgraded. These results will be used to refine the geological interpretation to guide future exploration targeting.
Highlights from new results include:
§ 0.6m @ 35.06g/t Au & 0.04% Cu from 478m (THO25RCD014)
§ 2.9m @ 2.35g/t Au & 0.06% Cu from 318.4m (THO25DD013)

Figure 12: Oblique section A showing results from hole THO25RCD014 and historic drilling
O’Callaghans (Tungsten-Copper Deposit)
The O’Callaghan’s deposit is a tungsten, copper, lead, and zinc sulphide deposit located approximately 10km south-southeast of the Telfer mine and a globally significant high grade tungsten deposit outside of China, and has historically been listed as both a Reserve and Mineral Resource by Telfer’s previous owner, but was not declared as either a Reserve or a Mineral Resource by Greatland in its March 2025 update (four months post-acquisition of Telfer) as technical evaluations to support such classifications had not been completed at that time.
A 1,200m diamond drill hole was completed to advance the understanding of the structural architecture and geology beneath the deposit. The hole was co-funded through the WA Government Exploration Incentive Scheme (EIS) and was designed to test modelled magnetic anomalies and seismic reflectors beneath the mineralised skarn. The drilling has provided valuable geological and structural information that will support ongoing interpretation and exploration work. Assay results from the program are pending.
Camp Dome
The Camp Dome prospect is a satellite copper-only oxide deposit located approximately 20km north of the Telfer mine. The deposit was historically reported as a Mineral Resource by Telfer’s previous owner Newcrest Mining Limited, but has not been declared as a Mineral Resource by Greatland until adequate technical evaluation is conducted.
Drilling has commenced testing for extensions to primary copper mineralisation below the oxide deposit. Two diamond holes and two pre-collars have been completed for a total of 1,430m, partial assay results have received for two holes.
Highlights to date include:
§ 44.4 m @ 0.32% Cu & 0.01g/t Au from 412m (CD25RCD003)
§ 7m @ 0.81% Cu & 0.02g/t Au from 106m (CD25DD002)
§ 19.8m @ 0.32% Cu & 0.01g/t Au from 147.8m CD25DD002
Although preliminary, results to date have confirmed grade continuity through the supergene and primary mineralisation models, a full review will be conducted when remaining assay results have been received. The program has been temporary placed on hold until the end of the wet season, and it is anticipated to resume in the June 2026 quarter.

Figure 15: Oblique section B showing results from hole CD25RCD003, historic drilling and copper mineralisation interpretations
Pinnacles
The Pinnacles prospect is located approximately 1km southeast of the West Dome open pit, along the trend of the West Dome anticline structure (Figure 7).
Drilling is currently underway targeting the western limb of the Lower Limey Unit (LLU) unit, host to multiple ore bodies at Telfer’s West Dome and Main Dome open pits and undergrounds, 1km along strike from previous drilling.
Paterson South Farm-In & Joint Venture
The Paterson South Project consists of seven exploration tenements which cover a combined area of 1,080km2 (shown in Figure 7).
The Paterson South Project is the subject of a farm-in and joint venture arrangement between Greatland Paterson South Pty Ltd and Rio Tinto Exploration Pty Limited (RTX), a subsidiary of Rio Tinto Limited (ASX/LSE:RIO), to accelerate exploration across the tenure in the Paterson region
Farm-In milestone
During the December quarter, Greatland completed the Stage 1 Farm-In by spending $7.1 million and completing drilling of at least 7,500m in aggregate, earning a 51% interest in the Paterson South Project tenements and forming an unincorporated joint venture with RTX over that project (Greatland 51% : RTX 49%). Greatland is the joint venture manager.
RTX is currently considering whether to exercise its right to contribute to its 51% share of future joint venture expenditure. If RTX does not exercise this right, Greatland intends to sole fund the Stage 2 Farm-In requirements, allowing Greatland to earn up to a 75% joint venture interest.
Teague
RC and diamond drill (DD) testing of geological, magnetic and structural targets at the Teague prospect (Figure 16) was completed, with 3 holes drilled for 1,240.1m.
Drilling targeted an interpreted anticlinal fold structure which hosts mineralisation further along strike to the northwest at the Triangle prospect (Figure 16). Three drill holes were completed in late 2024. Holes TRS002RCD and TRS004RCD intersected zones of variably anomalous Au, Cu, Bi and As mineralisation associated with brecciated, reef style quartz veining and associated sericite, hematite and carbonate alteration. Three RC pre-collared DD tailed holes were drilled to follow up this mineralisation.
Figure 16: Teague prospect, Triangle South; completed holes on reduced to pole 1st vertical derivative aeromagnetic image, with drill section lines in pink
Drilling successfully intersected similar style Au – Cu – As – Bi mineralisation, associated with zones of massive to semi-massive pyrite rich sulphide, with traces of arsenopyrite and chalcopyrite, observed within sericite-carbonate altered, brecciated, stockwork quartz veined fine grained sandstones.
Mineralised intercepts received to date include:
§ 8m @ 1.30g/t Au from 241m (incl. 3m @ 3.11 g/t Au from 241m) (TRS007RCD)
§ 15m @ 0.40g/t Au from 150m (incl. 4m @ 0.98g/t Au from 161m) (TRS007RCD)
§ 3m @ 0.65g/t Au from 385m (incl. 1m @ 1.58g/t Au from 385m) (TRS005RCD)
Results from drillhole TRS006RCD are pending.
Further detailed interpretation of the lithogeochemistry, pathfinder anomalism, geology and structure will be completed once all assays are returned.
Follow up work will be planned for testing of the continuity and orientation of the mineralised zones intersected to date, with over 500m of strike between the two drill lines completed at Teague by Greatland (Figure 16). Mineralisation is open down and up dip, and along strike to the northwest and southeast.
(Figure 16). Mineralisation is open down and up dip, and along strike to the northwest and southeast.

Ernest Giles Project
Greatland’s 100% owned Ernest Giles project (Figure 18) is located in the Eastern Goldfields region of Western Australia, 250km northeast of Laverton.
Figure 18: Ernest Giles Project and Yamarna Belt location
Exploration work completed in 2025 was focused on the Meadows target area situated in the south-east end of the Ernest Giles Greenstone belt. The diamond drilling component of the program was completed during the quarter, with 11 holes for 2,195.8m, giving a total of 20 RC and RCD holes for 7,479.1m over several target areas, within the Meadows prospect.
Encouraging anomalous gold intersections have been returned from the recently completed DD tails and are being analysed. Results include:
§ 9m @ 0.72g/t Au from 349m (EGD009) including;
– 3m @ 1.30 g/t Au from 349m; and
– 1m @ 2.43 g/t Au from 354m
Results for the last seven diamond core tails are still pending.
Mineralisation appears to be stratabound within ironstones (BIF) which dip at ~65o toward 025o, matching the long axis of the IP anomaly and approximating the magnetic trend (Figure 19).
It is likely that the drill line to the north did not intersect the mineralised zone, as the zone is cut off by the younger cover sequence in hole EGD011 on that line (Figure 19). The zone is open up-dip and to the north and south. Follow up drill plans will be confirmed once all assays have been returned and interpreted.
