Develop Global Limited (ASX: DVP) (Develop) is pleased to report on a highly successful March quarter, during which the company declared commercial production at its Woodlawn copper mine, progressed its Sulphur Springs copper-silver-zinc project towards a final investment decision and started preparations for a DSO lithium mine.
Develop Managing Director, Bill Beament said: “It was pivotal quarter for Develop as we made huge progress across our three mining projects, setting up the Company for rapid growth.
“Woodlawn has met and exceeded our targets, culminating in the start of commercial production during the quarter. We are now set to increase cashflow generation as mining moves into higher-grades, coupled with historically low treatment charges.
“We have developed the mine well ahead of the schedule, reducing the risk and giving us lots of flexibility, putting this project in a very strong operational and financial position.
“We are adopting the same approach at Sulphur Springs, where the underground decline is well ahead of schedule and long-lead items have been ordered for the processing plant.
“There is very strong interest from third parties wanting to play a role in project financing and offtake and we are on track for a final investment decision in the current quarter.
“At the same time, we are examining ways to capitalise on the resurgent lithium price at our Pioneer Dome project where grade control drilling is underway with the aim of establishing a high-margin direct shipping ore operation.
“Again, we are in discussions concerning funding and offtake and we will compile full tenders to supply key services for the execution of the project in the current quarter.
“These projects are progressing rapidly in parallel with our growing mining services division, which will see us lodge tenders for A$2.5b of work in this quarter.
“The market for our services is extremely favourable and we are confident that we will, continue to grow revenue in this part of our business”.
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.

Mining
Mine development and ore tonnes achieved steady-state production:
-
181,973 of ore mined from development and stoping sources, of which 80,510 was in the month of March
-
Mining production rates were successfully stressed tested at 960ktpa – above the current 850ktpa
-
Ore stoping continued in the Kate, G, H & I lenses; with additional development ore from H, I, D & N lenses
-
Kate Lens contributed 59% of ore tonnes for the quarter
-
1,874.1 development was completed
-
Decline advanced down to the 221RL (590 metres below surface)
-
Priority headings were the South Decline, 2425 I & D Access and 2270 Drill Drive/EXD, which is a critical drilling platform for project DM15 (extending the mine life from 10 years to 15 years)
-
Additional accesses completed at 2440 & 2490 (Kate lens) 2255, 2275, 2285 (I & D lenses) to improve stope availability and schedule flexibility (Figure 1)
-
Paste fill infrastructure installation continued for the I and D lenses
-
Grade-control and resource definition continued within the I, D and N lenses
Mined grades are expected to increase and be closer to LOM Reserve grades in the June Quarter with the highgrade core of Kate lens scheduled to come online (Figure 2).

Processing
The concentrator achieved nameplate processing rate in March, reaching steady-state production. Plant utilisation was at 94.6% for the quarter, including an exceptional 99.4% in March.
A total of 176,550 tonnes of ore was milled for the quarter, with a monthly record of 77,741 tonnes processed in March. Milled rates were also successfully stressed tested at 930ktpa – above the target of 850ktpa.
14,119 tonnes of concentrate was produced for the quarter, marking a 50% increase compared to the December quarter. This included a 101% increase in copper and a 30% rise in zinc production. Lead production was down 10%, driven by periods of low lead feed grades, where no lead concentrate was produced.
All metal concentrates were within contractual specifications.
Processing recoveries were lower than the definitive feasibility study metrics, which was expected, due to the lower ore feed grades into the plant especially the lead feed.
Mined ore grades for the March quarter improved by 41% from the December quarter and are expected to be closer to the LOM Reserve grades in the June quarter which should result in further improvements in recoveries. Significant progress on both grades and recoveries has been seen in the month of April.
Surface ore stockpiles totalled 15,000t at the end of March (up 1,000% from Dec-Qtr), with additional underground broken ore stocks of 13,000t. Unsold concentrate stocks totalled 11,845t (~A$33M) (up 180% from Dec-Qtr), majority of these stocks were shipped in April with revenue to be realised in the June Quarter.
Optimisation of the concentrator continues, with focus on improving metal recoveries across the board given the better understanding the polymetallic ore zones and plant operating parameters, recent advancements include:
-
An ore blending strategy has been implemented to stabilise feed presented to the concentrator. This has helped optimise throughput, concentrate quality and metal recovery through steady operation
-
Continued work on geo-metallurgy to gain insights into the performance of future ore zones across the different lenses
-
Modifications to the copper flotation circuit to improve residence time and further increase processing capacity
-
• Improvements in the zinc concentrate grade with changes to the reagent scheme and plant water quality pretreatment processes
Additional operational projects were also completed:
-
Upgraded the copper concentrate thickener underflow pump to facilitate higher concentrate production
-
Onsite laboratory capabilities have been broadened to allow testing for both volume and a wider assay suite, including precious metals
-
Received approval for stages 2 and 3 dam lifts for tailings disposal

Exploration and Growth
In-mine grade control and resource definition drilling continued at Woodlawn with 14,539m completed. Drilling focus was on grade-control and resource definition activities within the D, G, Kate and N lenses.
Assays results received during the quarter identify thick, high-grade copper-zinc-lead-silver-gold mineralisation within the G, I, D and N lenses, with a significant number of these hosted outside the current resource shapes.
Significantly, the extremely high-grade mineralisation intersected within the G lens (5.3m @ 0.7% Cu, 12.3% Pb, 16.6% Zn, 845.7gpt Ag & 7.8gpt Au) is hosted in an area that was previously thought to be barren; additional assays are expected this quarter to help define the geometry and size of this bonanza zone.
Significant intersections include:

During the quarter the company also commenced an exploration drilling program at the nearby Currawang Prospect located approximately 10km northeast of Woodlawn.
The Currawang deposit was previously mined in the early 1990’s producing 0.5Mt @ 1.2% Cu, 2.2% Pb, 13.0% Zn & 33pgt Ag. Following closure and rehabilitation in 1996 only minimal exploration has been completed. The current program is designed to test for extensions to mineralisation below these historic mining areas.
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 continued in preparation for a final investment decision (FID) in the June quarter 2026. Off-take negotiations, project financing and pre-development activities progressing well.
Works included continued clearing of the mining and processing infrastructure footprints, and mining of the underground declines. The underground declines are 15% ahead of schedule with 887m of single-jumbo development completed during the quarter (Figure 3 ).
GR Engineering Services is contracted to deliver the final engineering drawings. Long lead items for the processing plant have been ordered with deposits paid.
The General Manager for the mine has been recruited and commenced in the role.

PIONEER DOME LITHIUM PROJECT
The Pioneer Dome Project is located in Western Australia’s Eastern Goldfields, approximately 130km south of Kalgoorlie, and hosts a Mineral Resource Estimate of 11.2Mt at 1.2% Li2O. The project is fully permitted and shovel ready, with the potential to be Australia's next lithium operation.
Following the recent recovery in the lithium market, Develop has moved rapidly to commence evaluation of Pioneer Dome as a Direct Shipping Ore "DSO" project with a view to near-term development. Improved market conditions have restored demand for alternative sources of lithium supply, including spodumene DSO, with strong inbound interest from both end-users and commodity trading groups for Pioneer Dome’s DSO product and attractive pricing indications.
Develop engaged with a broad group of potential offtakers during the quarter, receiving eleven non-binding indicative proposals before shortlisting four groups to progress towards binding offtake agreements covering the initial 12 months of DSO production. All shortlisted proposals include price hedging provisions for up to 12 months, limiting price risk and providing near-term revenue certainty.
In parallel with the offtake process, Develop commenced a fast-tracked Definitive Feasibility Study “DFS” on the DSO pathway, alongside early works, with a Final Investment Decision “FID” targeted for the June 2026 quarter. DFS workstreams are advancing rapidly, with execution-level mine designs and production schedules finalised, budget pricing secured for key operational components including open pit mining, mobile crushing and pit-to-port haulage, and full-form tenders issued to prospective contractors.
Early works activities initiated included the acquisition of a 40-person mobile accommodation facility, appointment of a dedicated Mining Manager and commencement of recruitment for other key operational roles.
Exploration and Growth
A combined infill and exploration drilling program commenced at the Cade Lithium-Tantalum Deposit in late March with 33 holes (3288m) of Reverse-Circulation (RC) drilling completed.
The ~20,000m program is designed to improve confidence in the expected geometry and grade distribution of the orebody for the proposed starter pit along with providing operation coverage for potential future pit and/or underground expansion scenarios (Figure 5).
Drilling results to date have intersected thicker than modelled mineralised spodumene pegmatite throughout the drilling target, with numerous intersections of >40m widths. The mineralization style is also highly encouraging, with high-grade, spodumene-only intersections with no accessory lithium-bearing micas identified. Initial interpretations also include the identification of a potential third pegmatite located withing the proposed Cade pit.

A$12.4m was spent on early decline development and pre-construction works at the Group’s Sulphur Springs copper, silver and zinc project in the Pilbara. This early decline development work continues to derisk the project by ensuring that the mine plan will have as much flexibility as possible when production starts and will also allow the existing ore body to drilled out and extended from underground prior to production. The pre-construction works including site clearing and engineering and flow sheet design, will enable construction to start as soon as possible after the final investment decision.
-
The Group started to mobilise equipment, inventory, and people to New Zealand for the commencement of its new mining services contract with Oceana Gold at the Waihi project. The cash spend on this mobilisation during the quarter was A$12.1m, of which A$6.0m will be recovered through financing of equipment purchased for in cash and refunding of GST paid on equipment and goods as they entered New Zealand.
-
With ship availability delayed due to the issues in the Middle East, shipments of ~5,000 WMT of copper concentrate and ~5,700 WMT of zinc concentrate were pushed from March to early-April. These two shipments were valued at A$28.9m. As a result, operationally Woodlawn had negative cash flow of A$16.2m for the March quarter, with A$11.6m also spent on growth capital.

Copper Equivalent ('CuEq') estimates for FY26 are calculated based on the following average forward commodity prices for FY26 as at 30 June 2025: Cu US$9,871/DMT, Zn US$2,795/DMT, Pb US$2,067/DMT, Ag US$37/oz, Au US$3,307/oz. Copper Equivalent is calculated using the following formula: Copper metal tonnes + Zn metal tonnes x (Zn price/Cu price) + Pb metal tonnes x (Pb price/Cu price) + Ag metal ounces x (Ag price/Cu price) + Au metal ounces x (Au price/Cu price).
-
Gold assay capability was installed at Woodlawn during the March 2026 quarter. No gold recoveries or contained gold have been reported for prior periods.
-
Recovery figures represent the percentage of each metal recovered from all ore sources into all concentrates during the period.
-
Realised prices represent the weighted average prices received for each metal, based on the revenue credits attributable to each metal in from Copper, Zinc and Lead concentrate sales during the period.
-
Stockpiles include Run-of-Mine ('ROM') stockpiles and crushed ore stockpiles. The balance shown is the closing stockpile balance at the end of the quarter.

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. |
• 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.). |
• 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. • |
| 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. |
• 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 Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. • The total length and percentage of the relevant intersections logged. |
• All diamond core were geologically logged for the total length of the hole. Logging routinely recorded weathering, lithology, mineralogy, mineralisation, structure, alteration and veining. • Logs are coded using the company geological coding legend and entered directly into the company database. • The following quantitative descriptions were used when logging, amongst others: oTrace less than 1% sulphides.oStringer 1-20% sulphides.oDisseminated 20-60% sulphides.oMassive sulphides greater 60%. |

| Sub-sampling techniques and sample preparation | • If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • 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. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
Grade control drill core are sampled as whole core and submitted for analysis • Exploration drill core are cut with an automated core-saw with half core samples submitted for analysis and the other half retained on site for future reference. • The majority of samples were dry, with good to excellent recoveries. • The sample size of 1.0-7.0kg is considered appropriate and representative for the grain size and style of mineralisation |
|
| 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. • 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. • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
• 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).

| 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. |
• 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 +47.0 to -76.4 and azimuth of 034 - 320 degrees (GDA2020). • Drillhole designs are considered appropriate for the geometry of the host sequence. |

| 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 security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
• Tarago Operations Pty Ltd (Tarago Operations), a wholly owned subsidiary of Develop Global Ltd, has held Special (Crown & Private Lands) Lease No. 20 [S(C&PL)L20] since March 2014. The lease was renewed on 21 January 2015 for a further 15 years and expires on 16 November 2029. • In November 2000, Collex Pty Ltd obtained development consent to operate a waste bioreactor on the old Woodlawn mine site using the open cut void.

| • dip and azimuth of the hole • down hole length and interception depth • hole length. • 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. |
||
| 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. |
• 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’). |
• 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 60-95% of the downhole width unless otherwise indicated. |
| 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. |
• 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. |
• Tables 1 & 2 present assays data for the current batch of drill holes. |
| 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. |
• Given this is a mature stage project with historical mining and regularised resource and grade control drilling underpinning Mineral Resources, no substantive exploration data has been recently collected at the project. • Geotechnical, metallurgical, bulk density, rock characteristic testwork was completed to feasibility study level of detail in 2016 by Heron. • |
| Further work | • The nature and scale of planned further work (e.g. tests for lateral _extensions or depth extensions or large-scale step-out drilling). _ |
