In addition factors contributing to the estimated break-even cut-off grade in Table 4 were altered even though the resultant cut-off grade remained constant at $140/t AgEq. These were a reduced silver price to be more consistent with that used in MRE equivalent metal calculations, lower mining costs assuming owner operated sub level cave mining, lower exchange rate to be more consistent with lower commodity prices used and increased mining recovery to reflect a more bulk style mining technique. These revised assumptions used for the mine gate break even costs and resulting cutoff grade are within the range of similar sulphide floatation underground operations in Australia and are considered to be reasonable for justifying Clause 20 of the JORC Code, Realistic Prospects of Eventual Economic extraction. The assumptions made are also considered reasonable and reflected in the category of Mineral Resource.
This announcement has been approved by Lode’s Board of Directors.

WEBBS CONSOL HIGH GRADE RESOURCE
Lode Resources Limited (ASX:LDR, Lode Resources or the Company) is pleased to announce a maiden Mineral Resource Estimate ( MRE ) for 100% owned Webbs Consol precious and base metals project located in the New England Fold Belt in northeastern New South Wales. The MRE, classified according to the 2012 edition of the JORC Code as Inferred and Indicated Resources at a 140g/t AgEq lower cutoff, contains:
1.6 Mt @ 636g/t AgEq[1] g/t for 32 M Ounces AgEq[1-4]
Webbs Consol is a historical mining centre which is known for historic high-grade silver-base metal-bearing lodes. The maiden MRE is a culmination of Lodes ‘s collation of exploration data from a number of recent drill campaigns carried out by Lode Resources. All of the information used for this MRE was derived from Lodes’s exploration and prospect scale drilling campaigns over the last 4 years listed at the end of this report.
The result marks a significant advancement in the Company’s understanding of the Ag ‐ Zn-Pb sulphide mineralisation associated with the Webbs Consol Leucogranite in the New England Fold Belt of New South Wales. The MRE confirms the scale and quality of the Webbs Consol Ag-Zn-Pb lodes. Development of a Mineral Resource Target as well as further resource definition and extension drilling on Webbs Consol and adjacent mineralisation is under active consideration.

2 Previous Mining and Exploration
Webbs Consol was discovered in 1884 and worked intermittently until the 1970s. Several mine shafts were worked for high-grade galena and silver.
Modern exploration commenced with CRA on historic EL1079 Exploration between 1978 and 1984. Silver Mines Ltd continued exploration on EL6239 between 2004 and 2014.
3 Geology
==> picture [6 x 6] intentionally omitted <==
The Webbs Consol Project hosts several high-grade, silver-zinc-lead mineralised pipes located over a 2km strike length within the margins of the Permian Webbs Consol Leucogranite (See Figure 2).

Figure 2. Webbs Consol project geology, mineralised lode locations and 97 drill collar positions
Mineralisation is hosted in silica-sericite-chlorite altered pipes solely within the Webbs Consol Leucogranite. Mineralised and altered pipes are aligned along a north trending lineament subparallel to the western granite-volcanic/sediment contact. Six mineralised pipes have been delineated by Lode Resources. A similar lineament is potentially located on the eastern margin.
Mineralogy consists of disseminated and blebby style silver-rich galena, sphalerite, pyrite, chalcopyrite and tetrahedrite. The mineralised pipes are approximately circular of 20-50m diameter in plan view with a steep elongate plunge. The mineralised pipes have been drill defined up to 350m depth and remain open at depth (See Figure 3). There is a likely hood of extensions and additional mineralisation with ongoing exploration.

4 Sampling and Subsampling Techniques
All data used for the Webbs Consol MRE was derived from drilling totalling 97 holes for 11,199m. This is made up of mostly diamond drilling (70 holes for 8,919m), and limited reverse circulation (RC) drilling (27 holes for 2,280m). Mineralised core samples were derived from NQ2 diamond drill core. Due to the steep orientation of the mineralised pipes and drill access, drill spacing and orientation is variable with spacing between 20m and 80m. Drill spacing and orientation is reflected in the classification of the MRE.
All drill collars were located by differential GPS. Downhole surveys were completed on all diamond drill holes.
Drill core was reconstituted, measured for recovery and RQD, and then logged and sampled by experienced geological staff at Lode’s core storage facility in Armidale. Drill core sub sampling consisted of half NQ2 prepared using a core saw. Samples of 2-3kg were bagged on a 1m basis while respecting geological boundaries.
RC holes were drilled with a 5-inch hammer with sub samples collected in a three-way cone splitter. Samples of 2-3kg were obtained on 1m downhole intervals under the supervision of Lode’s geological staff.
QAQC procedures involved industry standard insertion of certified reference material (CRM), blanks and duplicates at the rate of 1 in 20 samples.
All samples were bagged and sealed in plastic bags before transportation to ALS laboratories in Brisbane by a licenced courier.
Tables of relevant announcements regarding drill holes previously released by Lode are listed in the appendices of this report.

5 Sampling and Assaying
All Lode drill core was analysed at the ALS laboratory in Brisbane. Sample preparation comprised drying weighing, crushing to 70% passing 2mm, riffle splitting 1.5kg sample and pulverising to 85% passing 75um (PREP32). Multi element analysis of a 25g sub sample involved four acid digest followed by ICP-AES analysis (ME-ICP61) with Au analysed by 30g fire assay (Au-AA30). Both fire assay and four acid ICP are considered industry standard total assay methods.
6 Quality Assurance Quality Control
Routine QAQC involved the insertion of Certified Reference Materials (CRM) and blanks for >5% of samples. Analyses of CRM reported within accepted limits.
7 Bulk Density
Bulk density determinations were made on 1,066 samples of diamond drill core using the Archimedes method. Samples form a mildly skewed distribution. No assessment of grade-density relationship was investigated. Bulk density values were interpolated into the resource block model using an Inverse Distance Weighted Squared (IDW²) interpolation. Blocks lacking direct sample support were assigned the mean bulk density of 2.86.
8 Modelling and Resource Estimation
Interpolation and modelling of the Webbs Consols MRE has been based entirely on diamond drill holes with the exception of a short program of RC drill holes which contributed to the delineation of the North Webbs Consol lode. Geology solid models used for the MRE were digitised using Micromine[TM] software on plan view flitches constrained by 50 g/t AgEq geochemistry (prior to 140g/t AgEq cut-off grade) and drill hole geological observations (See Figure 5). Grade interpolation was constrained within wireframe models.
==> picture [389 x 328] intentionally omitted <==
Figure 5. Oblique view of Tangoa West illustrating flitch modelling controlling digital models.
6
==> picture [185 x 41] intentionally omitted <==
Drillhole assays within solid models were composited on a 1m basis, consistent with the majority of the drill hole sampling. Zero values were inserted into the drilling database for un-assayed lengths of core. Composited data exhibited a skewed distribution with a mean value of 380 g/t AgEq and a median of 159 g/t AgEq. No top cuts were applied to the composited data used for interpolation. No variogram modelling was attempted.
A north-south oriented block model was created in Micromine[TM] . Model parameters are listed in Table 2.

Z 500 1,000 2 251
----- End of picture text -----
Grades were interpolated into the block model using inverse distance squared (ID²) weighting constrained by mineralised solid models. Block percentage factors were applied to accurately account for blocks that lie partially within the wireframes, ensuring a more precise estimation of volume and tonnage. Simple anisotropic search ellipsoids were used to populate the model on two passes to ensure all blocks within the mineralised solids were interpolated (See Table 3).

|---|---|---|---|---|---|
| 1 | 15 | 20 | 10 | 6 | 2 |
| 2 | 30 | 40 | 20 | 8 | 1 |
The estimate was validated by making visual checks of block grades and input data and global histograms of input composites v estimated blocks (See Figure 4).

9 Classification
The majority of the resource has been classified as Inferred Resource with a small portion classified as Indicated Resource according to the guidelines of the 2012 edition of the JORC Code. Confidence in the geology model, data quality and interpolation where drill spacing was less than 25m has been classified as Indicated Resource.
10 Mining and Metallurgical Modifying Factors
Preliminary metallurgical testwork was completed by ALS Metallurgical Services in Perth (ASX:LDR 14 December 2021). Preliminary flotation testwork performed on a composite sample of mineralisation resulted in the production of saleable Ag-Zn-Pb bulk concentrate. Metallurgical recoveries of 97.3% silver, 98.7%, zinc, 94.7% lead, 76.3% copper and 90.8% gold. It is Lode’s opinion that all the elements recovered to concentrates have a reasonable potential to be sold.
No mining studies have been completed for the Webbs Consol project other than preliminary assessment by the Competent Person. The morphology of the mineralised pipes suggests the majority of the resource is amenable to an underground bulk mining method such as sub-level open stope or sub-level cave mining. The top 70-100m of some of the lodes may be amenable to open cut mining at significantly lower mining costs.
The cost break even grade assumptions include industry mining and milling costs for similar scale operations, industry average payability, 2022 metal prices and recoveries approximated from Lode’s metallurgical test work (Table 4).
