CSIRO RESEARCH ENHANCES UPSIDE AT WEBBS CONSOL SILVER PROJECT
Australia’s national science agency, CSIRO, has completed a research study at Lode Resources’ Webbs Consol Silver Project in New South Wales, funded through the Entrepreneurs’ Programme Innovation Connections Grant (ICG002410).
CSIRO Research Highlights:
-
Structural analysis and 3D modelling of Tangoa West, Main Shaft and other prospects has identified the potential for lateral extensions to mineralisation. This has significant implications for estimating size of deposits and greatly assists drill target planning.
-
The relative depth of the differing styles of alteration appears constant at all prospects suggesting very limited rotation or block faulting indicating likely preservation of mineralisation around the entire perimeter of the Webbs Consol Leucogranite. To date exploration has focused only on a relatively small area.
-
A comprehensive understanding of mineral deposit genesis has been gained by integrating structural, geochemical, mineralogical, and mineral‐chemical data. This enables comparison with other similar deposits.
-
Through 3D models and the use of innovative geochemical indicators, validated by mineralogical and mineral‐chemical analyses, CSIRO have suggested distinct mineralisation styles and ore zones, thereby providing essential knowledge for improved mineral exploration at Webbs Consol.
Please note that this ASX release only broadly summarises the work completed by CSIRO as numerous specific findings are considered proprietary property of LDR and thus remain confidential.

Findings Summary:
-
A comprehensive understanding of mineral deposit genesis has been gained by integrating structural, geochemical, mineralogical, and mineral‐chemical data. This enables the direct comparison with other similar deposits.
-
Through 3D models and the use of innovative geochemical indicators, validated by thorough mineralogical and mineral‐chemical analyses, CSIRO have successfully discerned distinct mineralisation styles and ore zones, thereby providing essential knowledge for improved mineral exploration at Webbs Consol.
-
The successful outcomes of this research underscores the significance of multi‐scale and multi‐analytical techniques to constrain deposit parameters essential for mineral exploration.
-
The relative depth of the differing styles of alteration appears constant at all prospects suggesting very limited rotation and likely preservation of mineralisation around the entire perimeter of the Webbs Consol Leucogranite.
-
Structural analysis of Tangoa West and other prospects suggests potential areas for lateral extensions to mineralisation.
In 2023, CSIRO, funded through the Entrepreneurs Programme Innovation Connections Grant (ICG002410), was engaged to undertake a collaborative research project to achieve a comprehensive understanding of the characteristics of hydrothermal Zn‐Ag‐Pb sulphide mineralisation linked to the ca. 256 Ma Webbs Consol Leucogranite in the New England Fold Belt (NEFB). CSIRO produced a comprehensive 79-page research report titled “Webbs Consol silver and base metal deposit characterisation, New England Fold Belt, NSW”.

The project included mapping of structures in drill core and the field, covering prospects throughout the research area, including Copy Cat, Castlereagh, Mount Galena, Lucky Lucy, Lucky Lucy North, Main Shaft, and Tangoa West. The findings were integrated with existing structural information provided by Lode Resources, allowing the creation of 3D models that support the multi ‐ scale structurally ‐ controlled nature of mineralisation.
To constrain hydrothermal alteration styles (chloritisation and sericitisation) and mineralisation processes, CSIRO conducted whole ‐ rock geochemical analyses and micro ‐ analytical characterisations on unaltered granite and mineralised samples from a number of prospects (Tangoa West, Main Shaft, Castlereagh, and Lucky Lucy ‐ North). The results were integrated with whole rock assay data supplied by Lode Resources to geochemically classify the granitic intrusions and discriminate alteration and mineralisation zones.
A robust correlation between alteration styles and metal endowment was established through the integration of geochemical data, hyperspectral (FTIR) core logging results, petrophysical data, as well as micro ‐ XRF elemental mapping and mineralogical/mineral ‐ chemical characterisations of drill core samples.
The chloritised mineralisation are characterised by ‐ high Zn concentrations, with Fe rich sphalerite containing numerous chalcopyrite inclusions (chalcopyrite disease). The sericitised zones exhibit ‘ordinary’ sphalerite but enrichments in Pb and As, primarily manifesting as galena and arsenopyrite together with blebby chalcopyrite. Furthermore, the sericitised samples prominently feature Ag ‐ rich sulphide grains bound to galena ‐ chalcopyrite ± arsenopyrite assemblages. Similar Ag concentrations were observed in chloritized ‐ samples, but Ag rich sulphide grains are rare. This discrepancy may be attributed to the preferential uptake of Ag by sphalerite, or by the microscopic inclusions of chalcopyrite enclosed within the sphalerite.

By understanding the alteration style and mineralisation process at each prospect a consistent trend of hydrothermal alteration patterns and ore zones relative to elevation across the entire Webbs Consol mineral system can be observed.
Using a threshold elevation of 700 meters above sea level, consistent patterns are summarised as:
-
i. The lower ore zones (characterised Ag and Fe ‐ bearing Zn ‐ rich mineralisation) at Tangoa West and Main ‐
-
Shaft are consistently found at greater depths, below the 700 meter threshold, and;
-
ii. The upper ore zones (characterised by an assembly of Ag ‐ Zn ‐ Pb ‐ Cu mineralization) throughout the Webbs Consol mineral system predominantly appear at elevations exceeding 700 meters.
This observation suggests very limited rotation and likely preservation of mineralisation around the entire perimeter of the Webbs Consol Leucogranite.
At Tangoa West, zinc data from drillholes support steep ESE and ENE anisotropic fields (Figure 1), further suggesting that the mineralisation, regardless of whether genetic/structural connections between the two ore zones exist, are steeply plunging and overall linear.

The results of this research constrained ore genesis and comparisons with potentially similar vein/pipe ‐ like Zn ‐ Ag ‐ Pb deposits within the NEFB and on a global scale. The observation of chloritised Fe ‐ rich sphalerite mineralisation prevailing at greater depths, while sericitised Zn ‐ Pb ‐ As ‐ rich mineralisation occur at shallower levels, aligns with earlier reports of a vertical zonation pattern of metals at Webbs Consol. We interpret that the ‐ lower, deeper chloritised Zn rich zones have formed closer to hot fluid sources, perhaps at temperatures of up to 400 °C, resembling mesothermal mineralisation styles. In contrast, the upper ore zones may have formed under cooler conditions, promoting sericitisation in the 200 ‐ 300 ° C range.
Overall, we note similarities in terms of deposit geometry and mineralisation style compared to certain deposits associated with the Gilgai Granitic suites in the NEFB, such as the Conrad Mine. Additionally, similarities are noted with the Devonian Zeehan and Dundas Pb ‐ Zn ‐ Ag ore fields in Tasmania and several world ‐ class deposits located in orogenic belts of Central/Eastern Asia and Northern America.

Zinc Equivalent Grades
Since the commencement of drilling at the Webbs Consol Silver Project it was deemed that silver was the appropriate metal for equivalent metal calculations as silver is the most common metal to all mineralisation zones. This is still the case however zinc is becoming increasing dominant with depth and therefore LDR has decided to calculate both silver and zinc equivalent grades to demonstrate overall grades. Metal equivalent figures are a simple way to demonstrate overall grade with a single figure thus making comparisons easier for investors. All assumptions and formulae are outlined in the JORC Code, 2012 Edition - Table 1 located in the Appendix of LDR announcement dated 19 February 2024 and titled “Drilling at Webbs Consol North Delivers Solid Silver-Zinc Intercepts” and are repeated in the Appendix of this announcement.
Webbs Consol Project Overview
Located 16km west-south-west of Emmaville, Webbs Consol was discovered in 1890 with intermittent mining up to the mid-1950s. The Webbs Consol Project (EL8933) contains several small, high-grade, silver-lead-zinc-gold deposits hosted by the Webbs Consol Leucogranite, which has intruded the Late Permian Emmaville Volcanics and undifferentiated Early Permian sediments.
Several mine shafts were worked for the high-grade galena and silver content only, with high-grade zinc mineralisation discarded. Mineral concentration was via basic Chilean milling techniques and sluicing, with some subsequent rough flotation of galena carried out, however no attempt to recover sphalerite.
Ore mineralogy includes galena, sphalerite, marmatite, arsenopyrite, pyrite, chalcopyrite, minor bismuth, and gold. Chief minerals are generally disseminated but also high-grade “bungs” where emplacement is a combination of fracture infilling and country rock replacement. Gangue mineralogy includes quartz, chlorite and sericite with quartz occurring as veins and granular relicts.
Historical sampling shows potential for high-grade silver and zinc mineralisation at Webbs Consol, and it was reported that 12 spot samples taken from the lowest level of the main Webbs Consol shaft (“205’ Level” or 60m depth) averaged 210g/t silver, 22.6% zinc and 2.74% lead. Epithermal style mineralisation occurs in ‘en échelon’ vertical pipe like bodies at the intersection of main north-south shear and secondary northeast-southwest fractures. No leaching or secondary enrichment has been identified.

Commentary |
Commentary |
|---|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg 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 (eg ‘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 (eg submarine nodules) may warrant disclosure ofdetailedinformation. |
• • • • |
No new drilling has been carried out at the Webbs Consol Silver Project. All drill hole core assays have been previously reported. The CSIRO collected a total of 45 quartered core sub-samples from 8 previously assayed and reported drill holes (WCS006, WCS009, WCS012, WCS020, WCS023, WCS031, WCS045 and WCS047) forqualitative analyses only. All core sub-samples (45) collected by the CSIRO where subjected to whole‐rock chemical analysis and XRD analysis for mineralogical characterisation. Selected core slabs (13) were polished for elemental mapping. Subsequently, polished thin sections were prepared at CSIRO’s micro‐analytical facilities. |
| Drilling techniques |
• Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). |
• | No new drilling has been carried out at the Webbs Consol Silver Project. |
| 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. |
• | No new drilling has been carried out at the Webbs Consol Silver Project. |

No new drilling has been carried out at the Webbs Consol Silver Project. All drill hole core assays have been previously reported. The CSIRO collected a total of 45 quartered core sub-samples from 8 previously assayed and reported drill holes (WCS006, WCS009, WCS012, WCS020, WCS023, WCS031, WCS045 and WCS047)for qualitative analyses only. All core sub-samples (45) collected by the CSIRO where subjected to whole‐rock chemical analysis and XRD analysis for mineralogical characterisation. Selected core slabs (13) were polished for elemental mapping. Subsequently, polished thin sections were prepared at CSIRO’s micro‐analytical facilities. |

Whole ‐ rock geochemistry
Whole ‐ rock chemical analyses (45 samples) were carried at LabWest Minerals Analysis Pty Ltd. (Perth, Australia). Alkaline fusion method on major (Al2O3, CaO, Fe, K2O, MgO, MnO, Na2O, P2O5, SiO2, TiO2, and LOI (loss on ignition) and resistive trace elements (Ba, Ce, Cr, Dy, Er, Eu, Gd, Hf, Ho, La, Lu, Nb, Nd, Pr, Sc, ‐ Sm, Sn, Ta, Tb, Th, Tm, U, W, Y, Yb and Zr) were analysed using the in house AF02 method, which involves fusion of the powdered sediments at 1000 °C using a lithium borate flux. The resultant glass bead is then dissolved in 5% nitric acid. Whole rock multi ‐ acid geochemistry for Ag, Al, As, Au, B, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Fe, Ga, Gd, Ge, Hf, Hg, Ho, In, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, P, Pb, Pd, Pr, Pt, Rb, Re, S, Sb, Sc, Se, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn, Zr was performed ‐ ‐ by LabWest Minerals Analysis using their in house method, MMA 04. This method gives total recovery of all but the most resistate minerals. All elements are presented at ppm concentration, apart from Re which was measured at ppb level. 0.1 g of sample is digested in a mixture of hydrofluoric, nitric, and hydrochloric acid in ‐ sealed digestion vessels for 60 minutes, using an Anton Paar MW3000 microwave digestion system. The digestion takes place at a temperature of approximately 160°C and 16 bar pressure. After addition of boric acid to neutralise remaining hydrofluoric acid, the solutions are made to volume with deionised water. Internal standards are added to the solutions at the digestion stage. The solutions are then presented to ICP ‐ Mass ‐ ‐ ‐ Spectrometry (Perkin Elmer Nexion 300Q) and ICP Emission Spectrometry (Perkin Elmer Optima 7300DV) for determination of the desired analytes.
XRD analysis
The whole ‐ rock mineralogy of 45 samples was determined using a Bruker D4 XRD, which is equipped with a Co tube and an Fe filter, as well as a Lynxeye position sensitive detector. Analysis was performed using 5 ‐ 90° 2 ‐ theta range, 0.02° step size, 1° divergence slit, and a total analysis time of 60 minutes per sample. Minerals were identified using the Xplot software.
Microscopy
Polished thin sections were characterised at CSIRO’s micro ‐ analytical facilities in Perth. Thin section plane polarised, cross polarised, and reflected light images with a resolution of 2.5 m per pixel were acquired using ‐ a Zeiss AxioImager semi automated petrographic microscope.

1Since the commencement of drilling at Webbs Consol Silver Project it was deemed that silver was the appropriate metal for equivalent calculations as silver is the most common metal to all mineralisation zones. This is still the case however zinc is becoming increasing dominant with depth and therefore LDR has decided to calculated both silver and zinc equivalent grades to demonstrate overall grades. Webbs Consol silver and zinc equivalent grades are based on assumptions: AgEq(g/t)=Ag(g/t)+32.3Zn(%)+27.5Pb(%)+107Cu(%)+87.1Au(g/t) & ZnEq(g/t)=0.031Ag(g/t)+Zn(%)+0.850Pb(%)+0.2.694Cu(%)+2.57Au(g/t) calculated from 12 February 2024 (previously 29 August 2022) spot metal prices of US$22.7/oz silver, US$2325/t zinc, US$2060/t lead, US$8100/t copper, US$2020/oz gold and metallurgical recoveries of 97.3% silver, 98.7%, zinc, 94.7% lead, 76.3% copper and 90.8% gold which is the 4th stage rougher cumulative recoveries in test work commissioned by Lode and reported in LDR announcement 14 December 2021 titled “High Metal Recoveries in Preliminary Flotation Test work on Webbs Consol Mineralisation”. It is Lode’s opinion that all the elements included in the metal equivalents calculation have a reasonable potential to be recovered and sold.
