ASX Announcement 27 October 2023
- Woodlawn Copper Zinc Project, NSW
Numerous hits of +10% CuEq[1] show Woodlawn set for more growth in inventory and financial returns

Potential major extension to the high-grade Kate Lens:
-
1.7m @ 4.4% CuEq[1 ] intersected ~440m down plunge from Kate Lens
-
Results will be included in a further Resource and Reserve update scheduled for the March Quarter 2024; This will feed into a new mine plan
-
Underground ore development in the lowest level of Kate Lens has yielded significantly thicker mineralisation than modelled, potentially increasing production volumes
Develop (ASX: DVP) is pleased to announce outstanding assays which reveal the presence of many more zones of high-grade copper and zinc mineralisation at its Woodlawn copper-zinc mine in NSW.
Develop Managing Director Bill Beament said: “These exceptional results reveal additional high-grade mineralisation within the existing Resource and also extend the known mineralisation outside the Resource.
“This paves the way for further growth in the Resource and Reserve, which will in turn underpin another update in the mine plan.
“But they are also very important at the macro level because they add to a growing picture which shows Woodlawn is a significantly bigger mineralised system than has long been understood to be the case.
“This could have significant ramifications for production rates, mine life and what are already exceptional financial returns as forecast in our recently update mine plan.
“The potential is demonstrated by the several new lenses of mineralisation which have been identified in this drilling program as well as additional mineralised positions within the Resource.
"We have already established that Woodlawn is a substantial orebody with a plus-10-year mine life. But it is fast becoming clear that it could be significantly bigger”.
Woodlawn Project
Develop’s Woodlawn Copper-Zinc Mine is in the world-class Lachlan Fold belt in NSW. Historically, the Woodlawn Mine operated from 1978 to 1998 and processed 13.8Mt grading 9.1% Zn, 1.6% Cu, 3.6% Pb, 74g/t Ag and 0.5g/t Au. It was Australia’s second highest grade base metal mine at the time.
Following the mine acquisition in mid-2022 Develop has undertaken an aggressive growth focussed drilling programme that resulted in an updated Mineral Resource Estimate of 10.3Mt at 1.8% Cu, 6.1% Zn, 2.2% Pb, 47.2gpt Ag & 0.5gpt Au[2] (4.8% CuEq[1] ) (refer to ASX announcement titled “Woodlawn Resource increases by 40%” dated 11 October 2023).
Drill Programme Details
Develop’s maiden exploration and resource drilling campaign at Woodlawn commenced in late CY2022 from a purpose built underground drill drive. Due to the success of the initial programme, Develop immediately commence a follow-up programme. The current programme is designed to target extensions to, and infill the high-grade mineralisation intersected within the previous programme, including at the newly discovered copper rich J Lens where drilling intersected 9.9m @ 7.9% Cu and 4.2% Zn and 8.8m @ 7.6% Cu and 1.6% Zn (refer to ASX announcement titled “Woodlawn Drilling 10% copper, 4.2% zinc outside Resource” dated 05 May 2023).
Resource Infill
Assays results from resource infill and extensional drilling designed to increase the resource confidence level have continued to return thick, high-grade copper-zinc-lead-silver-gold mineralisation in multiple lenses. Significant intersections include:
-
10.6m @ 13.3% CuEq[1] (1.3% Cu, 22.5% Zn, 9.8% Pb, 137gpt Ag and 0.8gpt Au) from 303.9m (23WNUD0057; D Lens)

Several of the reported infill intersection are located fully or partially outside of the current resource boundaries. True widths of the intercepts reported are estimated to be approximately 75-90% of the downhole widths.
Assays results from drilling intersections located significantly outside of the recently updated October 2023 Resource have also returned significant high-grade copper-zinc-lead-silver intersections across several horizons, including the potential extension to the high-grade Kate Lens. Drillhole 23WNUD0044 intersected 1.7m of high-grade copper mineralisation (4.4% Cu and 18gpt Ag) located approximate 440m down plunge of the main Kate Lens. This intersection remains open down-plunge and along strike. A significant copper intersection into newly discovered B Lens – Northern Lens was also recorded:
-
1.7m @ 4.4% CuEq[1] (4.4% Cu and 17.9gpt Ag) from 386.5m (23WNUD0044; New Lens)
-
3.0m @ 3.7% CuEq[1] (3.2% Cu, 11.8gpt Ag) from 366.0m (23WNUD0065; B Lens North - New Lens)
Resource Infill – Historic Drilling
As previously reported (see ASX announcement 31 August 2023), following a review of the geological database and coreyard inventory, a number of unsampled resource infill drillholes completed by Heron Resources immediately prior to entering administration was identified. Additional results from this sampling have returned high-grade copper-zinclead-silver-gold massive sulphide intersections within the G Lenses, including:
-
2.8m @ 3.8% CuEq[1] (1.4% Cu, 4.6% Zn, 2.2% Pb, 15gpt Ag and 0.2gpt Au) from 29.9m (WNDD0243; G Lens)
-
15.1m @ 3.6% CuEq[1] (2.4% Cu, 1.5% Zn, 28gpt Ag and 0.6gpt Au) from 19.9m (WNDD0259A; G Lens)

Project Update
Recently completed capital development into the lowest planned production level (2410RL) established into the highgrade Kate Lens (1.2Mt @ 4.5% CuEq[1] ) has identified that mineralisation is significantly thicker (+10m) than modelled. Due to this Develop are currently assessing potential extension to the mine pan is this area.

1. Reported intercepts are determined using averages of length weighted contiguous mineralisation downhole. The lower cut-offs for are 1.0% for copper, lead and/or zinc. Significant intercepts may include samples below the cut-off values if the interval is continuous throughout a geological unit. Totals may not balance due to rounding.

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. |

Section 2: Reporting of Exploration Results
Criteria listed in the preceding section also apply to this section.
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| 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. The waste facility was within S(C&PL)L20 and is now operated by Veolia Energy Services Australia Pty Ltd. |
| Exploration done by other parties | • Acknowledgment and appraisal of exploration by other parties. |
• Previous exploration has been undertaken by a number of parties going back over 45 years. Modern exploration has been undertaken by TriAusMin and Herron Resources. • Several drillholes reported in this announcement were completed by previous owners Heron Resources. These holes were not previously logged or sampled. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The Woodlawn Deposits and associated targets are related to Volcanogenic Massive Sulphide systems. |
| Drill hole Information | • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: |
• Details of the drill holes are provided in Tables 1 & 2 within the body of this report. |
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • 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. • The copper equivalent grades for Woodlawn (Cu Eq) are based on copper, lead, zinc, silver and gold prices of US$8330t Copper, US$2160/t Lead, US$2315/t Zinc and US$23.5/oz Silver, and US$1926/oz Gold (price deck based on LME spot as 10/10/2023), with metallurgical metal recoveries of 89% Cu, 85% Pb, 92% Zn, 78% Ag and 43% Au respectively based on historical recoveries at Woodlawn and supported by metallurgical test work undertaken. The copper equivalent calculation is as follows: Cu Eq = (Cu grade % * Cu recovery %) + ((Pb grade % * Pb recovery % (Pb price $/t/Cu price$/t)) + ( Zn grade% * Zn recovery (Zn price $/t/Cu price$/t)) + (Ag grade g/t /31.103 * Ag recovery % * (Ag price $/oz/Cu price $/t)) + (Au grade g/t /31.103 * Au recovery %* (Au price $/oz/Cu price $/t)) |
| 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 75-95% 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 |
• Tables 1 & 2 present assays status for the current batch of drill holes. |

| 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. |
| 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). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive |
• Results from the current programme are planned to be used to produce an update to the Woodlawn Resource, along with providing geometallurgical data. • Future drilling programmes (including DHEM) are also being planned to target the depth/plunge extensions to mineralisation intersect in the current drilling. |
