Notes to Editors
Alien Metals Ltd is a mining exploration and development company listed on the AIM market of the London Stock Exchange (AIM: UFO). The Company's focus is on delivering a profitable direct shipping iron ore operation from its 90% Hancock iron ore project in the central Pilbara region of Western Australia. The Hancock tenements currently contain a JORC-compliant resource of 8.4Mt iron ore @ 60% Fe and offers significant exploration upside which is targeted to deliver a mining operation of 2Mtpa for 10 years.
These Hancock Project tenements have direct access to the Great Northern Highway, which provides an essential export route to export facilities at Port Hedland, from where more than 500Mt of iron ore is exported annually (30% of global production). The Company also has an interest in two iron ore exploration projects Brockman and Vivash, located in the West Pilbara.
The Company owns one of Australia's largest PGM deposits, Munni Munni which hosts a deposit containing a historic resource of 2.2Moz PGM (Palladium, Platinum, and Rhodium) and Gold. The Company has recently entered into a joint venture with West Coast Silver Limited (formerly Errawarra Resources Limited) for the development of the Elizabeth Hill Silver Project, located near Karratha in the Pilbara, which consists of the Elizabeth Hill Mining Lease and exploration tenements surrounding the historical silver mine which has produced some of Australia's highest-grade silver ore during the late 1990s.

Appendix A - ASX:WCE ANNOUNCEMENT
Accelerated Phase 2 Drilling campaign commences at Elizabeth Hill
Highlights
· Phase 2 diamond drilling to commence on 10 October 2025 at the high-grade Elizabeth Hill Silver Project (Pilbara, WA)
· Follows multiple bonanza-grade intercepts from Phase 1 (Aug-Sep 2025)
· Program aims to test near-surface high-grade mineralisation, and prospective areas down plunge of the historical workings with mineralisation open at depth
· Additional ~3,000m air core program scheduled to begin early November, targeting near-mine anomalies defined by recent geophysics
· Geophysics in progress: Transient Electromagnetic (TEM) and drone magnetic surveys continuing to refine targets along the Munni Munni Fault and parallel structures
· Drilling Contractor and WCE personnel have commenced mobilisation activities to site
West Coast Silver Limited (ASX: WCE) (West Coast Silver or the Company) is pleased to advise that the second phase of diamond drilling will commence ahead of schedule, on 10 October 2025, at the high-grade Elizabeth Hill Silver Project in the Pilbara region of Western Australia (Elizabeth Hill) (Figure 1, Figure 2, Figure 6).
The program has a dual focus: (1) to confirm and define the shallow, very high-grade silver immediately adjacent to the historic workings; and (2) to test a potential for deeper continuation to the south where the mineralisation remains open at depth.
The Phase 2 drilling program will consist of approximately 14 diamond drill holes (~1,300 metres). This will be expanded as required based on the success of the program. Drilling will be undertaken by Wallis Drilling Pty Ltd.
In addition, geophysical surveys have commenced to provide additional high-quality data for refinement of the proposed air core programs commencing in November (Figure 3, Figure 4, Figure 5).
Commenting, Executive Chairman Bruce Garlick said:
"We're back on the ground and moving quickly to build on the outstanding grades from our initial campaign. Phase 2 is designed to do two things: demonstrate near-surface continuity in the oxide zone and test a deeper target that could represent a down-plunge repeat of the Elizabeth Hill system.

Down Plunge Exploration Targets
Further evaluation of historical underground and surface drilling geology logs and geochemistry has reinforced the prospectivity of the down plunge target as a potential extension of the Elizabeth Hill Mine sequence (Figure 2).
Underground diamond drill hole UGD084 intersected 2m @ 1,995g/t Ag within an interval of 6m @ 705g/t Ag (Figure 1 ,Figure 2, Appendices 1-2). Drill logs at the time also describe native silver mineralisation within the 2m high grade interval, similar to that recorded in the Elizabeth Hill Deposit (WAMEX Report A62365).
Underground diamond drill hole UGD085 intersected 23,304 ppm Ni, 6,013 ppm Cu, 1,078 ppm Pb, 4,104 ppm Zn and 50 ppm Ag (Figure 1, Figure 2). The drill log describes complex textures with calcite brecciation reflecting similar geology to the Elizabeth Hill mine sequence (WAMEX Report A62365).
These drill holes combined with drill hole AG33 (Figure 1, Figure 2) previously reported, provide confidence in targeting the down plunge extension of the Elizabeth Hill mineralisation.

Geophysical Programs
Drone magnetic and Loupe TEM programs are currently being conducted on site. The Drone Magnetic survey is being flown at 20m line spacing to refine the targeting for planned air core programs, as well as defining further potential Elizabeth Hill style targets on the Munni Munni fault (Figure 3, Figure 4).

The Elizabeth Hill Project
· Elizabeth Hill is one of Australia's high-grade silver projects and has a proven production history outlined below:
· High grades enabled low processing tonnes: 1.2Moz of silver was produced from just 16,830t of ore at a head grade of 2,194g/t (70.5 oz/t Ag)[2].
· Previous mining operation ceased in 2000: because of low silver prices (US$5)[3].
· Simplistic historical processing technique: native silver was recovered via low-cost gravity separation techniques.
· Untapped potential remains in ground with deposit open at depth and recent consolidation of land package offers potential to discover more Elizabeth Hill style deposits.
· Tier 1 Mining Jurisdiction located on a mining lease with potential processing option at the nearby Radio Hill site.
Figure 6: Tenement Location
Through the consolidation of the surrounding land packages into a single contiguous 180km2 package, significant exploration and growth potential exists both near mine and regionally. The land package holds a significant portion of the Munni Munni fault system, and other fault systems subparallel to the Munni Munni fault system, which are considered prospective for Elizabeth Hill look-a-like silver deposits.
The upcoming Phase 2 program represents the next step in defining near-surface continuity and testing deeper repeat potential within this proven high-grade system.

JORC Code (2012) - Table 1 - Elizabeth Hill Silver Project, Western Australia
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)

Criteria |
JORC Code explanation |
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 of detailed information. |
· The historical exploration activities mentioned in this release have been obtained from open file data (WAMEX reports) extracted by Alien Metals, and other historical databases that Alien Metals has used to compile a master database. · The Competent Person (CP) confirms that sufficient spot checks of data in the Alien Metals master database, for selected historical drill holes, have been performed with the original WAMEX reports to verify the data extracted or captured in digital format, is as presented. The CP considers the data is fit for purpose for planning further exploration. · Data including procedure documentation have been obtained from Alien Metals. · West Coast Silver is undertaking a full validation of the nature and quality of the historical drilling and sampling undertaken. · West Coast Silver has however done sufficient verification of the sampling techniques, and in the CP's opinion it provides sufficient confidence that sampling was performed to adequate industry standards and is fit for the purpose of planning exploration programmes and generating targets for further investigation. · All references to historical mineralisation are taken from reports and documents prepared by previous explorers that have been reviewed by West Coast Silver and considered to be fit for purpose. · The CP concludes the results highlighted by West Coast Silver are anomalous and warrant further investigation, based on his experience in the areas of the Company's Project.
Drilling: Pre-2002 Historical Underground Diamond Drilling · Underground extensional exploration drilling consisted of diamond core drilling. Very limited information on sampling of underground holes (UGD001, 019, 021-22, 082-087) mentioned in the announcement and drilled by East Coast Minerals NL and Legend Mining Ltd in the early 2000's, is documented in the historical reports. However, sampling was undertaken on one or two metre intervals. · Laboratory protocols are not available to determine the laboratory sample size. · The historical reports mention a variety of methods and techniques for analysing the drill core. · The CP is unable to verify historical sampling work but considers they provide an indication of mineralisation and are sufficient to plan further exploration. |
|
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). |
Pre-2002 Historical Underground Diamond Drilling · Underground diamond drilling used either a Kempe Bazooka rig or LTK TT46 rig (~35mm core diameter). · The historical reports contain very limited information on drilling details and are not considered material to supporting the assessment of prospectivity and further exploration. |
|
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. |
Pre-2002 Historical Underground Diamond Drilling · West Coast Silver is undertaking validation of the historical data to determine whether this information has been collected in full. Only limited information is available in the open file reports addressing this criterion. However, for further exploration purposes, the CP regards this lack of information is not considered material. · These criteria will be partially validated within the Elizabeth Hill historical mine environment with twinning of some historical drill holes. |
|
Logging |
· Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. · Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. · The total length and percentage of the relevant intersections logged. |
Pre-2002 Historical Underground Diamond Drilling · Underground historical drill holes were geologically logged to various degrees of detail. · West Coast Silver is undertaking verification of the quality and level of detail of the geological logging data. · The historical reports show very limited and selective core photos of variable quality. No other details are known about the core photography. · West Coast Silver has done sufficient verification of the data, in the CP's opinion to provide sufficient confidence the logging was performed to adequate industry standards and is fit for the purpose of planning exploration programmes and generating targets for investigation. |
|
Sub-sampling techniques and sample preparation |
· If core, whether cut or sawn and whether quarter, half or all core taken. · If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. · For all sample types, the nature, quality and appropriateness of the sample preparation technique. · Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. · Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. · Whether sample sizes are appropriate to the grain size of the material being sampled. |
Pre-2002 Historical Underground Diamond Drilling · The CP can confirm the diamond core for UGD001 was cut and a quarter core sample was collected for assaying, while UGD019, 021-22, 082-087 were cut and half core samples taken for assaying. · Information on sample preparation is not available in historical reports. · Information for quality control procedures is not available in the historical reports. · Information on duplicates is available in the historical reports. · Sample sizes have not been described in the historical reports, except for UGD001 were it was mentioned "the small sample size may have been a contributing factor to problems recorded in obtaining correlation between lab results and core logging." · The CP can't verify if all the sample sizes were appropriate for the geology and style of mineralisation being investigated. However, the CP notes that for this style of mineralisation it is general industry standard to cut and collect half core drill samples for assaying. |
|
Quality of assay data and laboratory tests |
· The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. · For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. · Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
Pre-2002 Historical Underground Diamond Drilling · Assaying and laboratory procedures are not available for most historical drilling. However, where available this information is described as below. · Underground samples submitted to Analabs were analysed by A103, Al04, A140 A119, F641W, F660, GA101 and Screen methods. Those submitted to Genalysis were analysed by AX/AAS, FA/AAS, FA/GRA and SFA/GRA methods. Intervals with visible silver were generally analysed by screen fire methods. · The CP cannot independently verify the QAQC of these analyses. · West Coast Silver has done sufficient verification of the assay data, and in the CP's opinion it provides sufficient confidence the assaying was appropriate for the mineralisation present and is fit for the purpose of planning exploration programmes and generating targets for investigation. |
|
Verification of sampling and assaying |
· The verification of significant intersections by either independent or alternative company personnel. · The use of twinned holes. · Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. · Discuss any adjustment to assay data. |
Pre-2002 Historical Underground Diamond Drilling · Significant intersections have been taken from previous databases. The CP completed several spot checks of the source data and did not identify any issues with the reported intersections. · West Coast Silver has done sufficient verification of the data, and in the CP's opinion it provides sufficient confidence that data entry, data verification, and data storage was performed to adequate industry standards and is fit for the purpose of planning exploration programmes and generating targets for investigation. · No adjustments have been made to any assay data. |
|
Location of data points |
· Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. · Specification of the grid system used. · Quality and adequacy of topographic control. |
Pre-2002 Historical Underground Diamond Drilling · Historical underground drill holes were recorded in AMG co-ordinates, and an adequate number of surface and underground survey control points were established. Previous data in AGD 1984 AMG Zone 50 have been converted to MGA 94 Zone 50. · Drill hole pick-ups were conducted by a licensed underground survey contractor. Shaft plumbs of both the main and vent shafts were carried out to ensure correct orientation of underground headings. · Down hole surveys in historical underground drill holes were regularly taken using Eastman single shot camera surveys for measurement of hole trace. The CP cannot confirm how the dip was determined down the hole. · A Mineral Resource or Ore Reserve is not determined. · West Coast Silver has done sufficient verification of the data; and in the CP's opinion it provides sufficient confidence in the accuracy and quality of survey data and that it is fit for the purpose of planning exploration programmes and generating targets for investigation. |
|
Data spacing and distribution |
· Data spacing for reporting of Exploration Results. · Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. · Whether sample compositing has been applied. |
Pre-2002 Historical Underground Diamond Drilling · The underground diamond holes (UGD001, 019, 021-22, 082-087) mentioned in the announcement were drilled from within the historical Elizabeth Hill mine to test the prospective mineralised zone down plunge from the known silver deposit. · Drill spacing is variable. · No Mineral Resource or Ore Reserve are reported. · Sample compositing in the historical drilling is variable and ranges from 1m to 2m. |
|
Orientation of data in relation to geological structure |
· Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. · If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Pre-2002 Historical Underground Diamond Drilling · The local stratigraphy and contained mineralisation comprising the Elizabeth Hill silver deposit has a northerly trend and a near vertical dip. · The underground diamond holes mentioned in this announcement were generally drilled in fans of holes, with variable azimuths and dips, from a single underground position, and orientated from the east to the west. · The true orientation of mineralised bodies in this area is generally known and no bias is indicated through the drill orientation. |
|
Sample security |
· The measures taken to ensure sample security. |
Pre-2002 Historical Underground Diamond Drilling · Due to the historical nature of the data, this has not and may not be determinable. West Coast Silver believes that none of the historical samples have been preserved. |
|
Audits or reviews |
· The results of any audits or reviews of sampling techniques and data. |
· No audits or complete reviews of the sampling techniques and data has been undertaken by West Coast Silver or any independent parties. |
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. |
· The results reported in this announcement refer to drill holes wholly on M47/342. · The tenement lies within the Ngarluma Native Title claim. · The tenement is in good standing with no known impediments. |
|
Exploration done by other parties |
· Acknowledgment and appraisal of exploration by other parties. |
· The Elizabeth Hill deposit and adjoining area has been explored for Ni, Cu, PGM, base metals, Li and Ag mineralisation since 1968 when US Steel International Inc explored the area for base metals and nickel. · Massive silver was discovered in ~1994-1995 by Legend mining NL in a percussion drilling program. Further drilling followed, and in 1997 an exploration shaft and drive were sunk by East Coast Minerals NL. · Underground mining at Elizabeth Hill was conducted in 1999-2000 with additional drilling completed by East Coast Minerals NL, until the project was sold to Global Strategic Metals NL in 2012. Alien Metals Ltd purchased lease M47/342 in early 2020. · Considerable exploration for Ni, Cu, PGM was conducted by Hunter Resources dating back to the 1980s. · Helix Resources acquired the Munni Munni Project in the late 1990's and undertook a number of scoping studies. · In 2002, a SRK Mineral Resource estimate for PGE and Au was published in accordance with the JORC code. · Subsequently, Platina Resources undertook mining studies and two scoping studies for the PGE and Au mineralisation. · West Coast Silver Limited is in the process of verifying and collating all historical data. |
|
Geology |
· Deposit type, geological setting and style of mineralisation. |
· The Elizabeth Hill silver mineralisation is structurally controlled and is located on the eastern boundary of the north-south trending Munni Munni Fault. Mineralisation has been intersected over a 100m north-south zone along the boundary of the Munni Munni Fault, plunging south along the granite contact. The zone has an east-west width of 15-20m with the high-grade core restricted to around 3m width in the region of the underground workings. The mineralised zone is separated into several pods and occurs within a quartz carbonate chalcedonic silica breccia that shows veining. The silver occurs in fine disseminations, needles, veins, nuggets and platelets up to several centimetres in diameter. |
|
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: o easting and northing of the drill hole collar o elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o 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. |
· The historical drill collar location information relevant to this announcement has been provided in Appendix 1. |
|
Data aggregation methods |
· In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg 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. |
Pre-2002 Historical Underground Diamond Drilling · Assays reported are based on historical data in open file reports, and upon review have been treated at face value. · Since these are underground exploration results, there has been no top cutting, and all data are presented, either graphically or in tables in this announcement. · Drill core intersections reported in this announcement have been calculated using a 25g/t Ag cut-off and are length weighted. · No metal equivalent values are reported. |
|
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 (eg 'down hole length, true width not known'). |
Pre-2002 Historical Underground Diamond Drilling · Historical underground drilling has been undertaken on various drill orientations and thus does not represent true width intersections. Future work by West Coast Silver will involve validation and reinterpretation of previous results and the drilling of additional holes to determine the orientation of mineralisation and thus true widths. · The criteria of the geometry of the mineralisation with respect to drill hole angle is not applicable, as the geometry of the mineralisation with respect to the drill angles has yet to be verified. · The intercepts reported are downhole length and the true width is not known. |
|
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. |
· Appropriate plans and figures have been included in 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. |
· All relevant and material exploration data to highlight the target areas discussed have been reported or referenced. · The five elements Ag, Cu, Ni, Pb and Zn have been reported as this reflects what was only analysed for in the mineralised zones of the historical underground diamond drill holes (Appendix 2). · Drill assay information for the West Coast Silver drilling has been released in previous ASX announcements. Significant drill assay information for the historical surface drilling in this release has been released in previous ASX announcements. |
