Updated High-grade copper intercepts extend Europa
29Metals Limited (‘ 29Metals ’ or, the ‘ Company ’) refers to its announcement earlier today in relation to results from Resource Conversion and Resource Extension drilling at Golden Grove. This updated release includes a new Appendix 3 setting out the relevant 2023 Mineral Resources Estimates summary table and relevant confirmations. The drilling results reported in this release have been prepared and are reported in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (2012 Edition) (the ‘ JORC Code ’).
Highlights[1] :
-
Resource Extension drilling intercepted high-grade copper mineralisation approximately 100 metres below existing Europa Mineral Resource estimates[2] , results included: - G24/159A: 43.9m @ 3.0% Cu, 0.4g/t Au, 18g/t Ag, from 955.1m
-
- G24/159A: 32.6m @ 2.7% Cu, 0.4g/t Au, 16g/t Ag, from 1,009.4m
-
- G24/162: 16.6m @ 4.9% Cu, 0.5g/t Au, 30g/t Ag, from 937.5m
-
Europa Resource Conversion drilling returned high grade copper intercepts, including: - G24/162: 25.8m @ 6.9% Cu, 0.6g/t Au, 42g/t Ag, from 864.5m
-
Europa is a future planned ore source at Golden Grove, within approximately 155 metres of the existing Xantho Extended decline.
-
Europa Mineral Resources[2] remains open down dip and along strike. Potential mining cost synergies exist between Xantho Extended and Europa, by progression of the Xantho Extended decline between the Xantho Extended foot wall and Europa hanging wall.
-
Xantho Extended Resource Conversion drilling confirmed high grade zones, results included: - G24/162: 19.8m @ 22% Zn, 0.2% Cu, 0.5g/t Au, 50g/t Ag, 1.6% Pb, from 490.1m
-
- G24/160: 21.4m @ 10.5% Zn, 0.3% Cu, 1.0g/t Au, 22g/t Ag, 0.4% Pb, from 455.9m
-
The results reported today are not included in 29Metals’ 2023 Mineral Resources & Ore Reserves estimates[2] at 31 December 2023 (reported on 23 February 2024). Commenting on the drilling results, Chief Executive Officer, James Palmer, said: “As a high-grade, copper dominant mineralised zone, today’s results highlight Europa’s potential to add even more copper weighting to Golden Grove’s future production mix. These results build on a long history of successful Resource Extension drilling at Golden Grove, which has progressively expanded the Gossan Hill and Scuddles mine lives since first production over 30 years ago. With results like the ones today from an existing mining front, and the potential for establishment and expansion of a new mining front at Gossan Valley, we see a lot of opportunity to build on this history of successful mine life extensions at Golden Grove.”

ASX Announcement High-grade copper intercepts extend Europa
Background
The Europa mineralised zone is one of 29Metal’s in-mine growth focus areas, located in the lower Golden Grove formation in the footwall of Xantho Extended. Historic drilling at Europa is limited as recent exploration activity has focused primarily on extensions of Xantho Extended, which is currently Golden Grove’s highest value ore source.
The results reported in this release are from a 3-hole program designed to test down plunge extensions of Europa along with testing the continuity and orientation of the mineralisation within the current Mineral Resource estimates[2] . An underground drill platform within the existing Xantho Extended development was used for the drill program, resulting in drill holes passing through existing Xantho Extended Mineral Resources estimates[2] en route to the Resource Extension target areas. Hence, drill holes reported in this release are classified across Resource Conversion, and Resource Extension drilling categories.
Figure 1 shows a long-section of Golden Grove, illustrating the boundary of 29Metals’ Mineral Resources estimates[2] , and highlights the target area for the drilling results reported in this release. December 2023 Mineral Resource estimates[2] for Xantho Extended and Europa is 9.6Mt @ 2.0% Cu, 6.7% Zn, 0.8g/t Au, 32g/t Ag, and 0.3% Pb, for 195kt Cu, 640kt Zn, 241koz Au, 9,724koz Ag, and 29kt Pb[3] .

Results
Exploration drilling results from the recent 3-hole drill program intersected broad zones of copper mineralisation below the existing Europa mineralised zone, made up of massive to semi-massive pyrite and chalcopyrite. The most significant Resource Extension interval was 43.9m @ 3.0% Cu, 0.4g/t Au, 18g/t Ag[1] .
The drilling expands the potential mineralised area of Europa down plunge of existing Mineral Resource estimates[2] , which presents a sizable exploration opportunity. Europa mineralised zone remains open down dip and along strike, and is approximately 155 metres from the existing Xantho Extended decline.
Europa Resource Conversion drilling intersected copper-rich lenses of massive to semi-massive pyrite and chalcopyrite. The most significant Europa Resource Conversion interval was 25.8m @ 6.9% Cu, 0.6g/t Au, 42g/t Ag[1] . The relationships between the mineralisation zones and between Xantho Extended and Europa orebodies are shown in Figure 2.

Resource Conversion drilling intercepted zinc and copper mineralisation within the Xantho Extended Mineral Resource[2] and copper mineralisation to the east of Xantho Extended within the Europa Mineral Resource[2] . Xantho Extended mineralisation intersected zinc-rich lenses made up of massive to semi-massive pyrite and sphalerite stratigraphically adjacent to copper rich lenses made up of massive to semi-massive pyrite and chalcopyrite. Some mixing of these zones is observed.
Full details of the reported drilling results are included in Appendix 1 and JORC Code Table 1 disclosures are set out in Appendix 2.

Section 1 - Sampling Techniques and Data
| CRITERIA | COMMENTARY | COMMENTARY |
|---|---|---|
| Sampling techniques |
|
Samples have been collected through diamond drilling (“DD”), from underground. Sample length is preferentially set to 1m and ranges from 0.5m to 1.0m of half core. Sample intervals do not cross geological boundaries; this ensures |
| samples were representative of the lithological unit without mixing of grade at lithological boundaries. There is no limit for shortest sample interval in the | ||
| database controls currently, though Geologists are recommended to not sample intervals shorter than 0.5m. | ||
| | Entire half core samples are crushed and pulverised to 85% passing 75µm. | |
| | Measures taken to ensure sample representativity include the collection and analysis of field and coarse crush duplicates. | |
| Drilling techniques |
|
DD diameter drilled NQ2, The Reflex Act II™ tool is used for core orientation marks on all DD holes. |
| Drill sample | | Recoveries of DD core are recorded as percentages calculated from measured core versus drilled metres. The intervals are logged and recorded in the |
| recovery | database. | |
| | The rocks are very competent, and recoveries are very high with average core recovery greater than 99.5% for both mineralised and non-mineralised material. | |
| | Drilling process was controlled by the drill crew and geological supervision provides a means for maximising sample recovery and ensures suitable core | |
| presentation. Drilled core is reconstructed into a continuous run on an angled iron cradle for orientation marking. Depth is checked against depth provided on | ||
| core blocks. No other measures are taken to maximise core recovery. | ||
| Logging | |
All (100%) drill core are logged geologically using codes set up for direct computer input into the Micromine Geobank™ database software package. All (100%) DD cores are geotechnically logged to record recovery, RQD, Structural logging is recorded for all oriented core. DD cores are photographed wet. |
| | Logging is both qualitative and quantitative (percentage of sulphide minerals present). | |
| | Underground drill holes (100%) are logged in full detail from start to finish using laptop computers directly into the drillhole (Geobank) database. | |
| | Standard mineralised rock codes used. Standard weathering, alteration and appropriate geological comments entered. | |
| Sub-sampling techniques and |
| All DD core is half-cut onsite using an automatic core saw with samples always taken from the same side. Half core is used for routine sampling and quarter core for field duplicates. Current sample length ranges between 0.5 and 1m (historically this can have been from 0.2m to 1.5m) and is adjusted to geological |
| sample | boundaries. | |
| preparation | | The sample preparation DD core adheres to industry best practice. A commercial laboratory is used which involves: |
| - Weighing |
||
| - Oven drying at 90º C |
||
| - Coarse crushing to 6mm |
||
| - Pulverising in an LM5 to a grind size of 85% passing 75µm. |
||
| - Samples > 3kgcrushed to 2mm and split usinga rotarysplitter(this represents < 0.01% of total sample used for Mineral Resource estimation). |

| - Collection of 400g pulp from each sample; rejects kept or discarded depending on drilling programme. |
||
| | Duplicates are taken after coarse crushing and pulverisation at a rate of 1:20 alternating between the two. These are subject to the same assay process as | |
| routine samples. | ||
| Quality of assay data and |
| A four acid “near-total” digestion is used to determine concentrations for silver, copper, iron, lead, sulphur and zinc. This method underwent a change in October 2014 after extensive test work was conducted. Previously it used a 0.4g sample in a HF-HNO3-HClO4 digestion, with HCl leach and finished using |
| laboratory tests | ICP-AES. Since October 2014, the sample charge weight is 0.2g in the same acid digestion maintaining the sample/solution ratio as the previous method. | |
| There is no material impact as a result of this change and is an ore grade method suitable for use in VHMS deposits. | ||
| | A 30g fire assay with ICP-AES finish is used to determine the gold concentration DD core samples. This method was considered most suitable for determining | |
| gold concentrations in rock with sulphide rich material and is a total digest method. Grades above 10g/t are then determined using AAS. | ||
| | No geophysical tools, spectrometers or handheld XRF instruments have been used. | |
| | Matrix-matched certified reference materials (sourced from Golden Grove and prepared by Ore Research Pty. Ltd.) with a wide range of values are inserted at | |
| a rate of 1:20 into every RC and DD to assess laboratory accuracy, precision and possible contamination. A certified blank is inserted at a rate of 1:50. Four | ||
| Quartz flushes are inserted at the end of any significant ore horizon. | ||
| | QAQC data returned are checked against pass/fail limits once the results have been loaded into the database. QAQC data is reported quarterly and | |
| demonstrates sufficient levels of accuracy and precision. | ||
| | Sizing tests ensure the grind size of 85% passing 75µm is achieved. | |
| | The laboratory performs internal QC including standards, blanks, repeats and checks. | |
| Verification of | | Significant intersections are reviewed by a senior geologist and other site geologists. |
| sampling and | | No specific twinned holes have been drilled as a part of this program, as all core is diamond and has been orientated. However nearby drill holes show |
| assaying | compatible geology and results. | |
| | Assay data is retained in text files (.SIF) and stored once loaded into the database. | |
| | All drill core is stored for posterity at the onsite core farm. | |
| | The database has grown as each previous owner added data to it. During the 1990’s the database was in Explorer III, a Microsoft Access™-based application. | |
| In 2008 the data was migrated to a Micromine Geobank™ database. Validation of data has been performed during each migration and is periodically reviewed | ||
| against hardcopy records. | ||
| | An additional field in the results table is used to ensure all data is displayed in the appropriate units. This allows comparison of the data in standard units and | |
| aids in calculating Mineral Resource models. | ||
| | All re-assayed data will replace original results that failed QAQC; both results are retained in the database, with the results that failed QC being excluded from | |
| general use and export. | ||
| | Use of both DD and RC Historically indicates there is no significant bias between drilling methods. | |
| | All assaydata remains in its original state and has not been adjusted. | |
| Location of data | | All underground drillhole collars are picked up by 29Metals surveyors using a Leica TS-15 (total station) with an expected accuracy of 10mm. Surface |

CRITERIA COMMENTARY
-
Before 2016 all drillholes were down hole surveyed gyroscopically by the drilling companies (currently Swick) once each drillhole was completed. This was tied into a starting azimuth and dip picked up off the rod string by our onsite survey department while the rig was drilling. Surveys were also carried out every 30m using an Eastman single shot camera while the hole is in progress in order to track deviation.
-
From 2016 to March 2023 the Champ and Reflex north seeking tools have been utilised for both our rig alignment and surveying. Holes outside of 20 degrees dip are surveyed every 12m using the north seeking function while holes inside +/- 20 degrees are surveyed using the gyroscopic components of the tool every 30m while drilling and then at end of hole every 10m.
-
Post March 2023 rig alignments have been conducted using the Minnovaire Azimuth Aligner, whilst surveying the hole has been conducted using Reflex north seeking gyro tool. Holes are surveyed using the gyroscopic components of the tool every 30m while drilling and then at end of hole every 3m.
-
The accuracy and quality of historic surveys is generally unknown.
-
A local grid system (GGMINE) is used. It is rotated 52.4 degrees west of MGA94 zone 50. The two-point conversion is as follows: - 10,000m is added to elevation in order to obtain Local RL

Topographic measurement on most of the leases is by 1m contour generated from aerial photography, however topographic measurement within the active mine areas is by GPS with surface control point with an accuracy of 10mm.
-
Data spacing and The diamond drill hole spacing for the exploration results in this release is variable, given the early stage of resource extension drilling which is the subject of distribution this release. Further exploration drilling is required to reduce data spacing and increase geological confidence and grade continuity.
-
Drill data spacing ranges from less than 10m x 10m in the active mining areas to greater 80m x 80m in exploration areas.

| Exploration done by other parties |
|
Original definition and exploration drilling was performed by Joshua Pitt, of Aztec Exploration, in 1971. From 1971 until 1992 multiple joint ventures continued the definition of the Mineral Resource, with highlights being the Scuddles, A Panel Zn, B Panel Zn, C |
| Panel Zn and Cu discoveries. Parties involved include Amax Exploration, Esso Exploration, Australian Consolidated Minerals and Exxon. | ||
| | Exploration and drilling within the Golden Grove leases has been conducted on a near-continuous basis since 1991 by successive owners of Golden Grove | |
| Operations Pty Ltd – including, Newmont, Normandy, Oxiana, OZ Minerals, MMG, EMR Capital, and, most recently, 29Metals. | ||
| | Exploration of the Golden Grove Tenements is ongoing and being conducted by Golden Grove Operation Pty Ltd (a wholly owned subsidiary of 29Metals | |
| Limited). | ||
| Geology | |
The mineralisation style is volcanogenic hosted massive sulphide (VHMS) which occurs as sub-vertical lenses within layered sediments and volcanics. The Golden Grove deposits are located in the Murchison Province in the north-western part of the Achaean Yilgarn Craton in Western Australia, within the |
| Yalgoo Greenstone Belt. Mineralisation occurs at the base of the Warriedar Fold Belt (“WFB”) within a sequence of felsic to intermediate volcaniclastic | ||
| sediments, lavas and associated autoclastic breccias. | ||
| | The Golden Grove Domain that hosts the Gossan Hill and Scuddles deposits lies along the northeast flank of the WFB. The Mougooderra Fault (west), | |
| recrystallised monzogranite (east) and post folding granites (north and south) bound the domain. The current interpretation of the structure places the | ||
| Golden Grove Domain on the eastern limb of a syncline. The stratigraphyhas a westerly youngingdirection and dips steeplywest. | ||
| Drill hole | | Complete table of drill hole information for this announcement is listed in appendix 1 of this document. |
| Information | ||
| Data aggregation methods |
| Assay results are exported from the Geobank Database by Senior Geologists. The results are pasted into a weighted average excel spreadsheet to generate downhole grade intervals. General guidelines for weighted averages as follows: |
| - Copper intersections |
||
oTrigger value: 0.4% Cu |
||
oMinimum Interval length 4m |
||
oMinimum grade of final composite 1.5% Cu |
||
oMaximum total length of waste 3m |
||
oMaximum consecutive length of waste 3m |
||
oShort high-grade intervals can only be included if they exceed a minimum grade x length of 6%m |
||
| - Zinc intersections |
||
oTrigger value: 2% Zn |
||
oMinimum Interval length 4m |
||
oMinimum grade of final composite 5% Zn |
||
oMaximum total length of waste 3m |
||
oMaximum consecutive length of waste 3m |
||
oShort high-grade intervals can only be included if they exceed a minimum grade x length of 20%m |
||
| | Intervals with lower minimum final grades may be included in the results should they contain other base metals or precious metals in significant quantity. | |
| | No top-cut value has been applied to any element. |

| Relationship between |
|
All drilling reported as downhole length, true widths are estimated to range between 35-60% of down hole lengths. Host horizons are well understood with two underground mines in operation. |
| mineralisation | | District drilling confirms mineralisation is hosted within the same stratigraphic sequence as the operating mines and no fundamental change has occurred to |
| widths and | the structural framework of the host sequence. | |
| intercept lengths | | Orebodies tend to strike between 0-10 degrees in mine local grid and dip between 70-90 degrees to local grid west. |
| Diagrams | | See diagrams within the body of this report |
| Balanced reporting | | All drilling results for activities covered in this announcement have been reported without exception within Appendix 1. |
| Other substantive | | Geological framework for the broader leases has been developed through applying the geological model of the active mining areas along with surface |
| exploration data | mapping, and systematic diamond drilling. | |
| | Sedimentary facies south of the active mines are consistent with the Golden Grove stratigraphy present at Gossan Hill and Scuddles Mines. | |
| Further work | | Future work will entail continued diamond drilling across all areas discussed in this report. |
