Develop Global Limited (ASX: DVP) is pleased to announce strong progress across all its divisions in the December quarter.

As a result, the Company is set to reach its target of steady-state production at Woodlawn in the March quarter and is on track to make a final investment decision at its Sulphur Springs project in the June-26 quarter.

Develop Managing Director Bill Beament said: “It was a pivotal quarter for Develop which has set up the company for rapid growth in copper, zinc and silver/gold production.

“The impact of what will be a rapidly increasing production profile on our cashflow, particularly given the surge in commodity prices and the sharp falls in treatment costs, will be significant and more far-reaching than some in the market are expecting.

“Our five-year business plan targets annual production of 50,000t of copper-equivalent metal. The strong rampup at Woodlawn and the progress at Sulphur Springs puts us tracking well to our schedule.

“Securing the OceanaGold contract means our Mining Services division now has two third-party contracts as targeted in the five-year plan. And the revival in the lithium price gives us a pathway to meeting the goal of producing 200,000tpa of lithium spodumene concentrate, or the equivalent via DSO.

“At Woodlawn, the commissioning process has progressed extremely well, with both throughput and recoveries meeting or exceeding our forecasts.

“The success of the ramp-up was shown by the record throughput of 59,000t in the December. We are set to hit name-plate capacity of 850,000tpa this quarter.

“Given these strong results, we have started moving into higher-grade areas of the mine as part of our strategy to hit steady-state production in the coming quarter.

“With the mine already extensively developed thanks to our ‘bottom-up’ strategy, we have lots of flexibility and options to draw on as required during the ramp-up and beyond.

“At Sulphur Springs, the decline is progressing rapidly. This will serve several key purposes, including far better drilling access and ultimately forming part of a similar bottom-up mining approach to that at Woodlawn. This also significantly derisks the production execution of the mine plan for financiers.

“As well as zinc and copper, Sulphur Springs has a significant silver component. With the silver price at record highs, we look forward to advancing funding and offtake discussions ahead of a FID later this year.

“During the quarter, our Mining Services division secured a A$200m contract from OceanaGold to establish its Waihi North Project in New Zealand.

“This outstanding result is a testament to the skills of our people and the depth of our talent pool. I would like to congratulate them on winning this contract and thank OceanaGold for entrusting us to deliver their project.

“Since securing this contract, we have received many inquiries regarding our mining services, including from New Zealand projects.

“The quarter and subsequent to also saw a sharp increase in lithium prices, opening the door to a potentially significant opportunity at our Pioneer Dome lithium project in WA.

“We are assessing all the options at Pioneer Dome, which include a low capital cost production scenario such as a DSO operation, toll treating ore and building our own processing facility”.

Occupational Health, Safety, Environmental and Social

Group lost time injury frequency rate “LTIFR” was 0.0 (injuries per million work hours), National metalliferous mining average is 5.6.

There has been no material environmental or heritage incidents in the past quarter and Develop received no stakeholder complaints or grievances.

WOODLAWN COPPER-ZINC MINE

Develop’s Woodlawn Copper-Zinc Mine is in the world class Lachlan Fold belt in NSW. The project hosts a highgrade resource of 11.3Mt @ 1.8% Cu, 5.8% Zn, 2.1% Pb, 46gpt Ag & 0.5gpt Au and Reserves of 6.0Mt @ 1.5% Cu, 3.6% Zn, 1.3% Pb, 29gpt Ag & 0.4gpt Au.

Processing

The processing plant continued the commissioning and ramp-up process. Several planned, shut-downs early in the quarter were undertaken as an opportunity to execute key projects designed to increase throughput, recovery and concentrate grades in the longer term:

  • 9,472 tonnes of concentrate produced for the quarter

  • 141,009 tonnes of ore milled (record milled tonnage achieved in December, 59,000t)

  • First bulk shipments of both copper and zinc completed

  • Total concentrate produced increased 19% compared to the September quarter; copper 36%, zinc 43% and lead -29%

  • Metallurgy saw continued recovery increases, particularly within the copper circuit, October also achieved the highest recoveries of zinc since the restart of operations

During the quarter several optimisation projects were also completed:

  • Commenced using high chrome media 60mm/80mm blend into ball mill

  • Installation and commissioning of new Atomic Absorption Spectrophotometer (AAS) to produce gold assay onsite

  • Installation of new flotation machine to enable on-site metallurgical test work

  • Review of pumping process constraints and installation of equipment to match increased plant throughput

Revenue from Woodlawn concentrates sale in the December quarter was A$39.1M, up 98.5% from the prior quarter.

Exploration and Growth

In-mine grade control and resource definition drilling continued at Woodlawn with 9,772m completed.

Drilling focus was on grade-control and resource definition activities within the D, I, N and M lens’s, along with expansion and growth at the HWL and J lens.

Assays results received during the quarter identify thick, high-grade copper-zinc-lead-silver-gold mineralisation within the I, D and N lens’s, with a significant number of these hosted outside the current resource shapes. The N lens results are particularly meaningful, with this newly discovered lens expected to be able to provide an additional mining area within the next 3 to 6 months.

Significant intersections include:

SUPLHUR SPINRGS ZINC-COPPER MINE

The Sulphur Springs Project is located 144km south-east of Port Hedland in Western Australia’s Pilbara region. The project’s Mineral Resource stands at 17.4Mt at 5.8% Zn, 1.0% Cu, 0.3% Pb, 21gpt Ag & 0.2gpt Au.

During the quarter significant earthmoving activities were undertaken in preparation for a final investment decision (FID) in Q4 2026.

Works included reinstating access routes, clearing of the mining and processing infrastructure footprints, and mining of the underground access Boxcut and twin declines. All works have been carried out in collaboration and support from the Traditional Owners Group Nyamal.

The twin underground declines are well advanced with 543m of single-jumbo development completed during the

quarter.

Develop also announced the results of an Updated Definitive Feasibility Study (DFS) on the Project (see ASX announcement 09 October 2025). A summary is show below in table 2.

Project Revenue A$3.4 billion Up 18%
Free Cash-Flow(pre-tax real) A$1.5 billion Up 96%
Pre-Production Capital A$329 million Up 11%
Pre-Tax NPV8% A$921 million Up 76%
Internal Rate of Return(pre-tax) 59% Up 74%
Average Annual Pre-tax Cash flow (excludes capital
construction)
~A$252M Up 71%

Table 1 - Sulphur Springs DFS Summary

The results highlight Sulphur Springs’ exceptionally low cash operating costs, robust margins and outstanding economic returns based on an updated 1.5 million tonne per annum (“Mtpa”) underground mine. This allowed Develop to commence in the December quarter project off-take arrangements, project financing and predevelopment activities prior to a Final Investment Decision (FID).

The DFS indicates that Sulphur Springs will produce average annual recovered metal for years three to seven of

79ktpa of zinc and 11.5ktpa of copper.

The Project is forecast to generate life-of-mine (“LOM”) revenue of A$3.42 billion and LOM Project free cashflow of ~A$1.5 billion over an estimated 8-year mine life. Key DFS outcomes are shown in Table 3 below:

Exploration and Growth

A combined geotechnical, metallurgical and exploration drilling program was completed during the quarter, with 404.7m of diamond drilling completed.

Metallurgical drillhole 25SSMT002 was designed to drill down-plunge through mineralisation, optimising the amount of mineralised sample for metallurgical testwork. Assay results received recognise significant zones of high-grade copper-zinc-silver, including a new zone of footwall hosted, extremely high-grade copper-zinc-silver. Significant intersection include:

  • 203.9m @ 1.8% Cu, 0.6% Pb, 6.2% Zn, 21.0gpt Ag & 0.1gpt Au from 82.5m

  • Inc. 13.5m @ 2.4% Cu , 0.4% Pb, 13.1% Zn , 40.5gpt Ag & 0.2gpt Au from 82.5m

  • Inc. 15.4m @ 6.4% Cu & 11.6gpt Ag from 148.1m

  • Inc. 49.3m @ 1.8% Cu, 1.8% Pb, 15.2% Zn, 41.8gpt Ag & 0.2gpt Au from 193.7m o Including 3.2m @ 1.2% Cu , 50.9% Zn , 22.1gpt Ag & 0.2gpt Au from 213.7m

  • Inc. 17.6m @ 5.5% Cu , 1.3% Zn & 24.6gpt Ag from 247.5m

Geochemical analysis of the metallurgical assays identifies that mineralisation at Sulphur Springs is composed of two main phases divided into (1) copper and zinc rich massive sulphide horizons and (2) a late, extremely highgrade zinc/barium phase which overprints and upgrades the phase 1 mineralisation.

Notably, the extremely high-grade copper-zinc-silver mineralisation intersected within the footwall (49.3m @ 1.8% Cu, 1.8% Pb, 15.2% Zn, 41.8gpt Ag from 193.7m) is located outside the current resource shapes, at significantly elevated grades. Additional exploration drilling scheduled for later in 2026 will target extensions to this mineralisation.

Drillcore from this drilling will also be utilised for final metallurgical characterisations test work, design optimisation, and marketing.

PIONEER DOME LITHIUM PROJECT

The Pioneer Dome Project is located within Western Australia’s ‘lithium corridor’ in the Eastern Goldfields, approximately 130km South of Kalgoorlie. The Projects Mineral Resources stands at 11.2Mt @ 1.2% Li2O.

A significant increase in the spodumene price to ~US$2500/t SC6 and the re-emergence of the Direct Ship Ore (DSO) market has created an outstanding financial opportunity at this project.

In response to the escalating lithium pricing the company has recommenced commercial discussions regarding potential mine gate sales, toll treatment options and/or build its own processing plant for the 8.1Mt @ 1.2% Li2O production target (see ASX announcement 07 May 2024).

At US$2,000/t for SC6 spodumene, the scoping study where Develop built is own plant showed a pre-tax NPV8% of A$1 billion across a seven-year mine life while producing ~200,000t per annum of spodumene concentrate.

The project is fully permitted and would take less than 6 months to deliver first DSO ore at just A$35-40m capital cost if the Company goes down this pathway.

DEVELOP UNDERGROUND MINING SERVICES DIVISION

External revenue for the quarter was A$55.5 million, another excellent result.

At Bellevue, production activities were completed to schedule. Development was affected for 5 days due to an incident and subsequent investigation during December although achievement was still above target.

Key Physicals Achieved Q2 - 2026
Development Advance (Metres) 4,160
Total Ore Mined (Tonnes) 306,769

During the quarter Develop was awarded a 5-year ~A$200M tunnelling contract with Oceana Gold at its Waihi North project in New Zealand, due to commence June quarter 2026 (see ASX announcement 19 December 2025).

Develop is also currently in discussions with several companies regarding mining services tenders.

CORPORATE

Develop is rapidly establishing itself as the pre-eminent copper/base metals company on the ASX with unique capability to develop and unlock opportunities. Develop is engaged in ongoing discussions with various companies regarding business and partnerships opportunities.

The December quarter marks the second anniversary of Develop’s five-year business plan, under which it is targeting 50,000t per annum of copper-equivalent metal production. Based on progress to date, Develop believes it is tracking well compared to the schedule. The plan also targets two to three Mining Services contracts, Develop now has two.

High credentialled mining executives Duncan Bradford, Nathan Stoitis and Fraser Perry join the board and senior management team to bolster the skill and expertise of the Company during this extensive growth phase. Mr Bradford has a mining engineering background and was a former Mining Executive for the Gold/Base Metals Division of the US$75B Mining Conglomerate Ma’aden.

Mr Stoitis has a metallurgical engineering background and was a leading metallurgical consultant for the global hard rock extractive industry. He joined as Develop’s General Manager of Processing and Metallurgy. Mr Perry has a mining engineering/private equity background and was a former executive with the large Resource Private Equity company RCF. He joined as Develop’s General Manager of Business Development.

The funding process for the Sulphur Springs project commenced in the December quarter, with strong interest and engagement from domestic and international banks, resource credit funds, and global commodity traders. The offtake process will be run in parallel to the funding process, with both aiming to be complete to allow for final investment decision (FID) in the June quarter of 2026.

Notes:

  1. Ore Reserve figures are reported using cut-off grades or NSR calculation best suited to each deposit.

  2. Tonnages are dry metric tonnes. Minor discrepancies may occur due to rounding.

Cut-off Grades

Mineral Resources and Ore Reserves are reported using a block value filed (Net Smelter Return (NSR) $/t) after consideration of the contained metal, payability, concentrate transport cost, and state government, traditional owner and third-party royalties. Cut-off grades are calculated as a dollar per ore tonne, based on the forecast operating costs in the financial model. Economic analysis, including Stope Optimiser (SO) is carried out for each planned stope and only economically positive stopes are included in the Ore Reserve.

Section 1: Sampling Techniques and Data

Criteria JORC Code explanation Commentary
**Sampling techniques **
Nature and quality of sampling (e.g. 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.

Include reference to measures taken to ensure sample
representivity and the appropriate calibration of any measurement
tools or systems used.

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 (e.g. ‘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
(e.g. submarine nodules) may warrant disclosure of detailed
information.
Woodlawn & Sulphur Springs

Diamond Core drilling were used to obtain samples for geological
logging and assaying.

Core was nominally sampled 5m either side of logged
mineralisation.

Diamond core was cut and sampled at nominal 1m intervals, or
intervals determined by geological contacts.

The company used industry standard practices to measure and
sample the drill core.

0.3m to 1.1m half-core samples weighing nominally between 1.0 -
4.0kgs were submitted to the laboratory for multi-element analysis.
Drilling techniques
Drill type (e.g. core, reverse circulation, open-hole hammer, rotary
air blast, auger, Bangka, sonic, etc.) and details (e.g. 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.).
Woodlawn

Underground drilling was conducted by NQ2 core size.

Diamond coring was undertaken with an underground drill rig and
industry recognised quality contractor.

No was core orientation was completed due to ground condition
and limitations with obtaining continuous orientations lines.
Sulphur Springs

Surface drilling was conducted by HQ3 core size.

Diamond coring was undertaken with an track-mounted surface
drill rig and industry recognised quality contractor.

All drill core was orientation subject to obtaining continuous
orientations lines.
Drill sample recovery
Method of recording and assessing core and chip sample
recoveries and results assessed.

Measures taken to maximise sample recovery and ensure
representative nature of the samples.

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.
Woodlawn & Sulphur Springs

Sample condition, including estimated recovery and moisture
content were recorded for each sample by a geologist or
technician.

Core recoveries are recorded by the drillers in the field at the time
of drilling and checked by a geologist or technician.

When poor sample recovery was encountered during drilling, the
geologist and driller have endeavoured to rectify the problem to
ensure maximum sample recovery.

Insufficient data is available at present to determine if a
relationship exists between recovery and grade.
Logging
Whether core and chip samples have been geologically and
geotechnically logged to a level of detail to support appropriate

Woodlawn & Sulphur Springs

Samples from the current drilling program were assayed by
Australian Laboratory Services Pty. Ltd Orange/Brisbane/Perth.

Diamond Core samples were prepared and analysed by the
following methods:

Samples weighed, crushed and pulverised with the coarse residue
retained in vacuum seal bags (LOG-22, WEI-21, PREP-31Y).

48 elements are analysed by method ME-MS61 utilising 4 acid
digest, ICP-MS and ICP-AES; Over-limit/Ore-Grade samples are
analysed by method (ME-OG62). Au are analysed by fire assay
method Au AA23.

The company included certified reference material and blanks
within the at a minimum frequency on 1:20. Field Duplicated were
selected in zones of significant mineralisation at a frequency on
1:20.

In addition to Develop’s QA/QC methods (duplicates, standards
and blanks), the laboratory has additional checks.
Verification of sampling and assaying

locations used in Mineral Resource estimation.

Specification of the grid system used.

Quality and adequacy of topographic control.
Woodlawn

Underground drill hole collars are set-out and surveyed by a
qualified Mine Surveyor using a Total Station System.

Down-hole surveys are conducted by the drill contractors using a
north-seeking Reflex gyroscopic tool with readings every 10-30m
as the hole is drilled, and a continuous survey at the end of hole.

Grid systems used are the Woodlawn Local Grid (WMG).
Sulphur Springs

Drill hole collars are initially surveyed using a handheld GPS
operated by company personnel; at programme completion all
collars are located by qualified surveyors using a DGPS.

Down-hole surveys are conducted by the drill contractors using a
north-seeking Reflex gyroscopic tool with readings every 10-30m
as the hole is drilled, and a continuous survey at the end of hole.

Grid system used is MGA 94 (Zone 51).
Data spacing and distribution
Data spacing for reporting of Exploration Results.

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.

Whether sample compositing has been applied.
Woodlawn & Sulphur Springs

Data/drill hole spacing are variable and appropriate to the
geology and historical drilling spacing.

No compositing has been applied
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.

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.
Woodlawn

Drill holes at Woodlawn are designed to test mineralisation and
potential extension as near to perpendicular as possible (subject
to collar access with the exploration drill-drive); holes are drilled at
an angle between +40.0 to -76.4 and azimuth of 030 - 307 degrees
(WMG.

Drillhole designs are considered appropriate for the geometry of
the host sequence.
Sulphur Springs

Metallurgical drill holes at Sulphur Springs are designed to
optimise the amount of mineralised sample, therefore these are
drilled as near to parallel as possible (subject to collar positioning
and local topography).

Due to the sub-parallel intersection angles calculation of true width
and sampling bias are not possible.

Details of the drill holes are provided in Tables 1 & 2 within the
appendices of this report.
Data aggregation methods
In reporting Exploration Results, weighting averaging techniques,
maximum and/or minimum grade truncations (e.g. cutting of high
grades) and cut-off grades are usually Material and should be stated.

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.

The assumptions used for any reporting of metal equivalent values
should be clearly stated.
Woodlawn & Sulphur Springs

Results reported are determined by ALS Laboratories using
method ME-OG 62, ME-MS61 (over limit samples) and fire assay
AyAA-23.

All results are reported on a length weighting interval,

No top - cuts have been applied.

Any zones of cavity/no sample are assigned a grade of zero.
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 (e.g. ‘down hole length,
true width not known’).
Woodlawn

The geometry of mineralisation is well known and tested at this
deposit via DD drilling (and historical mining at Woodlawn). Across
the drillhole dataset angles to mineralisation are considered to
represent a drill intercept perpendicular to lens strike orientation.
With increasing depth the drillhole intercept angle to lens
decreases, however drilling from underground locations has
assisted in mitigating this issue for Measured and Indicated Mineral
Resources.

Drillholes are designed to intersect the orebodies at a nominal 90
degrees, however the local access, including mine design and
topography required all drillholes to be designed taking these
limitations into consideration to intersect the mineralisation.

True widths are estimated to be 75-95% of the downhole width
unless otherwise indicated.
Sulphur Springs

Metallurgical drilling at Sulphur Springs are designed to optimise
the amount of mineralised sample, therefore these are drilled as
near to parallel as possible (subject to collar positioning and local
topography).

Due to the sub-parallel intersection angles calculation of true width

Refer to Figures in the body of text within 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.
