JUNE 2023 QUARTERLY REPORT
Strong growth on all fronts positions Develop for energy transition boom
Outstanding exploration results at Woodlawn; Resource and Reserve increases and DFS completed at Sulphur Springs; Agreement to acquire lithium company Essential
Key Points
-
Develop enjoyed a highly successful quarter, generating strong growth in all areas of its energy transition metals business
-
At the Woodlawn zinc-copper project in NSW, drilling returned exceptional results of up to 10% copper and 4.2% zinc from outside the Resource. The drilling included the thickestever intersection at Woodlawn of 75m at 2.1% copper and 3.1% zinc (true thickness ~62m)
-
Rapid progress was made on site in preparation for a potential mine re-start; New Woodlawn life of mine plan set for release in the September quarter
-
At the Sulphur Springs zinc-copper project in WA, the fresh material in the Resource increased 32% and delivered a robust Underground Ore Reserve of 8.8Mt at 1.05% copper and 5.6% zinc
-
Updated DFS shows Sulphur Springs has pre-tax NPV of A$523m and is set to generate strong financial returns
-
On the 03 July 2023, Develop entered into a binding Scheme Implementation Deed with emerging WA lithium developer Essential Metals; Essential’s largest shareholder Mineral Resources has agreed to vote its 19.55% shareholding in favour of the Scheme
-
Develop launched a fully underwritten A$50m capital raising comprising of a $30m share placement and $20m entitlement offer; all major shareholders took up their full entitlements
-
• Develop formed a contracting joint venture with Tjiwarl Contracting Services. The agreement is aimed at securing contracts on Tjiwarl country
-
In the mining services division, Develop continued to exceed all the key targets in its underground mining contract at the Bellevue Gold Mine
-
The division completed ~3km of underground development at Bellevue, a 13% increase from the March quarter. This exceptional performance generated A$23M in contract revenue, a 20% increase on the March quarter
-
In light of this strong growth in all areas of its business and the Essential transaction, after the end of the quarter Develop advised Liontown Resources that it would not participate in the second-round tender for the underground contract at Kathleen Valley
Develop (ASX: DVP) is pleased to report on a highly successful quarter marked by strong growth across its portfolio of energy transition metal assets.
Develop grew the metal inventories at its Woodlawn and Sulphur Springs projects while advancing both towards production.
It also undertook due diligence on emerging lithium developer Essential Metals, culminating in the companies announcing a binding Scheme Implementation Deed under which Develop will acquire 100 per cent of Essential.
Develop Managing Director Bill Beament said: “We made huge progress towards our strategic goal of becoming a significant supplier of metals for the energy transition.
“Woodlawn gets better with every hole we drill. The results from drilling outside the resource were absolutely outstanding and highlight the huge upside at this project.
“We also changed the whole strategy and outlook for Sulphur Springs. By starting with an underground mine rather than an open pit, we have completely re-written the financial forecasts while significantly de-risking the project.
“And we moved to add lithium to our stable of energy transition metals with the Essential agreement. This is aimed at using Develop’s technical, operational and financial strengths to unlock the value of the Pioneer Dome lithium project in WA”.
Occupational Health, Safety and Environmental
Group lost time injury frequency rate “LTIFR” was 0.0 (injuries per million work hours), National metalliferous mining average is 2.4.
Group total restricted work injury frequency rate “RWIFR” is 2.7. This is the result of a single recordable injury for the quarter. WA metalliferous mining average is 6.8.
There has been no major or reportable environmental or heritage incidents in the past quarter.
Woodlawn Zinc Copper Mine
Develop’s Woodlawn Zinc-Copper Mine is in the world class Lachlan Fold belt in NSW, 250km south-west of Sydney. Historically, the Mine operated from 1978 to 1998 and was Australia’s second highest grade zinc equivalent mine at this time, processing 13.8Mt @ 9.1% Zn, 1.6% Cu, 3.6% Pb, 74gpt Ag and 0.5gpt Au. The projects current mineral resources total 7.3Mt @ 5.7% Zn, 1.8% Cu, 2.0% Pb, 44.9gpt Ag & 0.6gpt Au (see Mineral Resource Statements below).
Exploration
During the quarter, Develop completed a total of 19,186m of underground exploration drilling, finalising the company’s maiden 70-hole (~35,000m) exploration and resource drilling campaign. The program was designed to convert Inferred Resources to Indicated, extend the mineralised lenses at depth and along strike and drill-test highly prospective exploration targets.
Results received during the quarter from the exploration programme contained additional high-grade copper-zinc massive sulphide intersections across multiple horizons, including the thickest (continuous) sulphide intersection in the project’s history (see ASX release 16 May 2023):
-
75.0m @ 2.1% Cu, 3.1% Zn and 8.9gpt Ag from 351.0m (23WNUD00011) – B lens
oAnd 12.0m @ 1.0% Cu, 6.2% Zn, 3.9%Pb and 36.3gpt Ag from 20.0m – G LensoAnd 9.3m @ 0.4% Cu, 5.6% Zn, 2.8% Pb, and 18.0gpt Ag from 285.7m – A Lens -
2.1m @ 4.1% Cu , 1.0% Zn and 44.7gpt Ag from 103.8m (22WNUD0005) – G Lens
oAnd 5.7m @ 1.3% Cu from 497.0m – J Lens -
14.5m @ 1.4% Zn from 679.5m (23WNUD0001) – C lens
-
14.2m @ 0.7% Cu, 4.2% Zn, 2.6%Pb and 25.9gpt Ag from 11.1m (23WNUD0006) – G lens
oAnd 6.8m @ 2.9% Cu and 8.6gpt Ag from 471.1m – J lens
*The true widths of the intercepts reported are estimated to be approximately 65-90% of the downhole widths.
The extremely thick, copper-zinc intersection of 75.0m @ 2.1% Cu and 3.1% Zn (true with of approximately 62m) within 23WNUD0011 represents the thickest-ever continuously mineralised intersection in the project’s history. Importantly this mineralisation is located adjacent to the current life of mine plan (LOM) and can be easily incorporated into the mine schedule.
The copper-rich intersections from 23WNUD0006 (6.8m @ 2.9% Cu) and 22WNUD0005 (5.7m @ 1.3% Cu) follow on from and expand the previously reported high-grade mineralisation within the current program (see ASX release 05 April 2023), 20.0m @ 5.5% Cu (including 9.9m @ 7.9% Cu and 4.3m @ 6.8% Cu) and 8.8m @ 7.6% Cu. The style and tenor of mineralisation in this newly identified section of J Lens is extremely encouraging and suggested proximity to a high-grade feeder structure.
Exploration drilling targeting extensions to the north of the Woodlawn Resource has also intersected a series of stacked massive and stinger sulphide lenses located between 80m and 180m to the north of the current resource margin. Drillholes 23WNUD0062 & 23WNUD0064 intersected mineralisation up to 7.1m thick in downhole length (see Table 1 for details).
The lenses are interpreted to represent significant extensions to the Woodlawn deposit in an area that has not previously been tested with drilling, with the mineralisation open in all directions. Core samples have been submitted for laboratory analysis, and results are expected to be available in the September quarter.

Cautionary Statement: Visual estimates of sulphide mineral abundance should never be considered a proxy or substitute for laboratory analyses where metal concentrations or grades are the factor of principal economic interest. In addition, visual estimates also potentially provide no information regarding potential impurities or deleterious physical properties relevant to valuations.
Due to the success of the maiden exploration programme, Develop has elected to commence a follow-up infill and exploration programme immediately. A significant review of near-mine exploration targets within the Woodlawn Zinc-Copper Mine, along with regional targets, is also ongoing, with the aim of resuming both near mine and regional exploration activities in 2023.

Operations
The existing Woodlawn LOM is being redesigned and all operating costs are being updated. An updated LOM will be released in the September quarter. The restart costs for the processing plant are being finalised by GR Engineering and will be incorporated into the updated LOM.
An updated Ore Reserve will follow on from the completion of the updated mineral resource, due late this calendar year.
The diamond drilling contractor completed the initial exploration program on the 28[th] of June and one of the two rigs was demobilised. The continuation of the drill campaign will be designed to grow Resource confidence levels so Reserves can be increased and follow up the exploration success on near-mine targets identified in the recently completed program.
Excellent underground development rates have been achieved with month-on-month improvements culminating in site records in April, May and June of 323m, 327m and 388m respectively. This capital development is substantially de-risking a restart of the operation and will enable high ore production productivities to be achieved.
Sulphur Springs Zinc Copper Project
The Sulphur Springs Project is located in the world class Pilbara district in WA. The project hosts a Mineral Resource of 17.4Mt @ 5.8% Zn, 1.0% Cu, 21.0gpt Ag & 0.2gpt Au (see Mineral Resources Statements below).
During the quarter, the company released an updated Definitive Feasibility Study ‘DFS’ (see ASX release 30 June 2023). The DFS demonstrates a technically and economically robust project with a Pre-Tax NPV5% of A$523 million.
Updated DFS significantly de-risks Sulphur Springs:
-
All major project approvals have been granted (Ministerial environmental approval, Mining Proposal and Mine Closure plan)
-
The planned open pit in oxide and transitional material and satellite Kangaroo Caves deposit, which were in the 2018 DFS, have been removed from the Updated DFS; this reduces mineral inventory tonnages by 23% but improves the economics of the project
-
New mine plan is based on underground mining first, which reduces the upfront mining capital required and enables the metallurgically-superior fresh material in the Reserve to be accessed earlier
-
Reserves now account for ~91% of the mineral inventory underpinning the DFS compared with ~67% in the 2018 DFS
-
Capital and operating parameters re-costed in line with latest industry-wide inputs. This process utilised Develop’s in-depth understanding of underground costs due to its mining services division and extensive operating experience, as well leading independent consultants
-
Processing and surface infrastructure costings provided by industry specialist GR Engineering
-
Processing plant now includes a paste fill plant, which added A$34M to the upfront capital cost
Key findings of the updated DFS are highlighted below:
-
Significant value increase per tonne mined: 9% increase in revenue and 10% in NPV generated from 23% fewer tonnes mined
-
Average annual production for years one to four of 80.8kt of zinc metal and 16.4kt of copper metal in payable streams. Life of mine payable metal of 490kt zinc and 83kt copper
-
Zinc concentrate grade of 52% and copper concentrate grade of 23%
-
Only 135,000 tonnes of zinc metal is subject to an offtake agreement. There is no offtake agreement for the copper metal. This situation makes Sulphur Springs a highly desirable offtake partner for both metals
-
• Ore Reserve increased to 8.8Mt at 1.05% copper and 5.6% zinc
-
Mine life of 8 years post construction. Over the life of the mine it averages A$147M per year of pre-tax cashflow, before taking into account the initial construction capital costs
-
Project shows very strong economics in a current inflationary market
-
Upfront capital requirement of A$296M including:
-
A$234M for an improved 1.25Mtpa processing plant and other site infrastructure
-
oA$62M for mining pre-production, tailings dam construction, site access and accommodation -
Timing of clean energy transition metals and project timeline enables significant financial leverage from commodity price rises
-
Further opportunities to add value through exploration and increasing plant capacity
-
Kangaroo Caves deposit (3.8Mt at 0.8% Cu and 6.0% Zn) and the open pit at Sulphur Springs have not been considered in this updated DFS
Metallurgical Update
Following a review of historical and recent metallurgical test work, a refined definition of transitional and fresh geometallurgical domains has been identified at the Sulphur Springs deposit. This work has indicated that approximately 1.75Mt of material previously classified within the Mineral Resource Estimate (MRE) as transitional resources can be reclassified as fresh resources (see ASX release 2 June 2023).

Table 3: Key changes 2022 MRE Vs 2023 MRE
The MRE is reported at a A$80/t NSR cut-off. Tonnages are dry metric tonnes. Minor discrepancies may occur due to rounding.
Key changes to MRE due to the reclassification of Transitional to Fresh material in the 2023 block model update:
-
1,714kt less Transitional material
-
1,752kt more Fresh material (32% increase)
-
Net increase of 38kt from 2022 to 2023
The reclassification of transitional material to primary material is characterised by cleanly producing separate copper and zinc concentrates in a sequential flow sheet. This was based on a review of the historical work completed. Drill core intervals for the reclassified tests are bound in a 3-dimensional shape to minimise overstatement of the reclassification area. In total 16 tests, some of which were multiple tests on the same drill core, are indicative of material being primary ore.
These achieved improved zinc concentrate grade and recovery.

Table 4: Metallurgical performance of retested Transitional Zinc Ore
The updated metallurgy outcomes are exceptional and produce a marketable product via a simple conventional flowsheet with many potential cost (operating and capital) and environmental benefits.
The Sulphur Springs processing flowsheet has also been optimised from prior studies to reduce complexity and improve stability and quality. Additional metallurgical test work has identified opportunities that include;
-
Process plant design criteria weighted towards the treatment of fresh UG material, whereby historical design was developed on processing transitional and oxide material.
-
Change from SABC comminution circuit to 3-stage crushing with single Ball mill.
-
Simplified cleaner flotation circuits allowing reduction of internal recirculating loads.
-
Inclusion of a Pb removal stage to improve Cu and Zn concentrate quality. As Pb grades increase deeper in the ore body a saleable Pb concentrate will be produced.
-
Incorporation of paste fill via plant tailings will reduce tailings storage facility volumes.
Exploration
As previously announced (see ASX release 19 January 2023), Develop completed a 15-hole (5,584m) reversecirculation exploration drilling programme at the Sulphur Springs deposit. The programme was designed to test extensions to open mineralisation identified at the Trouser Leg and Eastern Lens targets during the updated 2022 Sulphur Springs Mineral Resource Estimate (MRE).
Assay results were received from the programme during the quarter (see ASX release 02 June 2023), including an exceptionally thick zone of high-grade zinc mineralisation within the Sulphur Springs Eastern Lens. Drillhole SSR013, which tested the down-plunge continuation of the Eastern Lens Exploration Target, returned an outstanding high-grade zinc intercept of 19m @ 20% Zn. The results from SSR013, when combined with historical drillhole data highlights an extremely thick, high-grade Zn core which remains open down plunge. Additional zones of low-grade mineralisation are also intersected within the Sulphur Springs Western Lens.
Significant exploration intersections include:
-
19m @ 20.0% Zn, 0.6% Cu, 0.7% Pb, 23.3gpt Ag & 0.5gpt Au from 387m (SSR013)
-
And 4m @ 3.3% Zn, 0.3% Cu, 4.7gpt Ag from 412m (SSR013)
-
• 4m @ 4.0% Zn from 264m (SSR021)
-
4m @ 2.9% Zn from 406m (SSR017)
SSR014 was abandoned prior to reaching target depth, no significant intersections were recorded in exploration holes SSR015 and SSR019, although both holes intersected very thick zones of pyrite-rich massive sulphide.

Develop Underground Mining Services Division
Develop continues to ramp up activities at the Bellevue Gold Project in Western Australia. The development contract to date has allowed for production activities to commence.
During the quarter, the division completed 2,964m of underground development at Bellevue Gold, a 13% increase from the March quarter. This exceptional performance produced A$23.0M in contract revenue, a 20% increase from the March quarter.
The fourth development crew commenced late in June and resulted in an instant ramp up in development advance. Month on month increases are anticipated as the fourth drill productivity is maximised.
Production work continues to build with substantial production drilling activities occurring throughout the quarter. Revenues continue to increase with the associated increased in mining physicals.
Elsewhere, Develop has withdrawn from the tender process for the underground contract at Liontown’s Kathleen
Valley project. The decision reflects:
-
The increased volume of work which will flow from a successful completion of the proposed Essential acquisition
-
The forecast labour requirements at our own mines, particularly given the rapid progress being made at both projects
-
The significant expansion in the scope of the Liontown contract between the first and second rounds of the tender, including the increased workforce requirement. This expanded scope did not fit Develop’s mining services business model
-
The strong inbound inquiries from potential mining services clients. Discussions are progressing with several potential clients in respect to projects scheduled to start in late 2023/early 2024.
Whim Creek Join Venture (20% free carried)
Develop has a 20% free carried interest with Anax Metals (ASX: ANX) in the Whim Creek Base Metal Joint Venture Project located 115km southwest of Port Hedland in Western Australia.
During the quarter project partner Anax was notified that the Department of Water and Environmental Regulation (DWER) has revoked the Environmental Protection Notice (EPN) issued in 2019.
Following the revoking of the EPN, DWER subsequently granted a Works Approval for the Whim Creek Copper Project. The securing of the Works Approval now completes all DWER approvals required for the commencement of construction activities at Whim Creek Copper Project.
Develop will continue to update shareholders as further results are released.
Evelyn Project [E47/1209]
No new work completed during the quarter.
Corporate
Highly experienced resources executive and chartered accountant Justine Magee was appointed as a Nonexecutive Director, effective 9 May 2023. Ms Magee has more than 30 years’ experience in the mining sector.
Elle Farris was appointed as General Counsel effective 12 June 2023. Ms Farris was previously Senior Corporate Counsel and External Relations for Newmont, the world’s largest gold mining company. In this role, Ms Farris has advised on strategies for both surface and underground mines, as well as major M&A transactions.
After the end of the quarter, on the 3rd of July 2023, Develop and Essential Metals Limited entered into a binding Scheme Implementation Deed under which Develop proposes to acquire 100 per cent of the issued shares in Essential by way of a Scheme of Arrangement (Scheme). The Scheme consideration is one new Develop share for every 6.18 Essential shares held, implying a fully diluted equity value for Essential of ~A$152.6 million and A$0.56 per share based on the closing price for Develop shares of A$3.46 per share on the 30 June 2023
An indicative timetable for the Scheme is set out below:

Also on the 3rd July 2023, Develop launched a fully underwritten A$50m capital raising comprised of a share placement to raise A$30m and 1-for-29 accelerated non-renounceable entitlement offer to raise a further A$20m (together, the Capital Raising). All major shareholders took up their full entitlements including Managing Director Bill Beament who contributed A$3.9m to the raise.
The capital raising offer price of A$3.20 per share represents a 7.5% discount to Develop’s last traded price on 30 June 2023 of A$3.46 and a 3.5% discount to the 5-day VWAP as at that date.
The proceeds of the Capital Raising will be used to:
-
Accelerate the development of Pioneer Dome (subject to successful completion of the Scheme), including drilling, metallurgical tests, approvals and updated economic and mining studies;
-
Payment of stamp duty and associated costs for the proposed transaction;
-
Prepare for the resumption of production at Woodlawn, including ongoing underground capital development which will significantly de-risk the production re-start;
-
Undertake further drilling at Woodlawn to follow-up on the recent significant exploration success and continue growing the mineral inventory for the life-of-mine plan

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. • 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 th laboratory for multi-element analysis. |

• Details of the drill holes are provided in Table 1 within the body 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 usedfor any reporting of metal equivalent values should be clearly stated. |
• Assay 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 |

statement to this effect (e.g. ‘down hole length, true width not known’). | 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. |
• Laboratory assay results are required to determine the widths and grade of the visible mineralisation reported in preliminary geological logging. The Company will update the market when laboratory analytical results become available for pending drillholes. |
| 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. |
