FREE MILLING HIGH GOLD RECOVERIES CONFIRMED AT HIGH-GRADE WAGTAIL DEPOSIT
Exceptional gold recoveries of up to 97.2% confirm Wagtail as a free-milling, high-grade gold deposit as drilling advances at Mt Fisher
HIGHLIGHTS
- Metallurgical test work on composite samples from the Wagtail Gold Deposit has returned excellent overall gold extractions of up to 98.7%, equating to ~97.2% recovery.
- Results confirm Wagtail mineralisation is free-milling and non-refractory, amenable to conventional gravity and cyanide processing.
- Key metallurgical characteristics include:
- Rapid leach kinetics, with essentially all cyanide-recoverable gold extracted within 8 hours.
- Low cyanide and lime consumption across all grind sizes tested.
- Limited grind sensitivity, with extractions remaining high from P₈₀ 180μm through to 75μm.
- Results indicate potential for processing at a coarser grind size, which may support improved mill throughput and lower operating costs.
- RC drilling continues at Mt Fisher, with 17 holes completed for 3,068m of the planned 5,000m program.
- Metallurgical and drilling results continue to support ongoing mining, toll-treatment and development studies being undertaken in partnership with SSH Group.
High-Tech Metals Ltd (ASX: HTM) ("High-Tech", "HTM" or "the Company") is pleased to report highly encouraging metallurgical test-work results from the Wagtail Gold Deposit, part of the Company's Mt Fisher Gold Project in Western Australia.
The metallurgical program was completed on a master composite sample generated from recent drilling at Wagtail and confirms the deposit hosts free-milling, non-refractory gold mineralisation suitable for conventional gravity and cyanide leach processing.
Test work returned excellent gold recoveries across a range of grind sizes, with overall extraction ranging from 96.8% at P₈₀ 180μm to 98.7% at P₈₀ 75μm.
Importantly, recoveries remained consistently high at coarser grind sizes, indicating strong processing flexibility and the potential for improved plant throughput in a conventional milling circuit.

High-Tech's Chief Executive Officer, James Merrillees, commented:
"These metallurgical results are an outstanding outcome for Wagtail and represent another major step forward in advancing the deposit toward potential near-term production.
"Recoveries over 97%, combined with rapid leach kinetics, low reagent consumption and moderate gravity recovery, confirm that Wagtail hosts exceptionally clean, free-milling gold mineralisation amenable to conventional processing methods.
"Importantly, the strong recoveries achieved at relatively coarse grind sizes could translate into lower processing costs and improved mill throughput in a production scenario.
"Combined with the recent drilling results, visible gold observations and the existing mining lease, these outcomes continue to strengthen our confidence in the broader Mt Fisher development strategy.
"At the same time, drilling at Mt Fisher is progressing well, with more than 3,000 metres now completed. We expect the first batch of assay results from that program within the coming weeks and look forward to updating shareholders as results are received."
SSH Mining COO Sam Baker Commented:
"We view these metallurgical results as a very positive outcome for the project and another encouraging milestone in the ongoing advancement of Wagtail.
"Achieving gold recoveries of up to 92.7% provides further confidence in the project's development potential and supports the technical work currently being undertaken by SSH and High-Tech Metals as we continue to assess pathways toward future mining operations."

These results have confirmed that Wagtail mineralisation is free-milling and suitable for conventional gravity and CIL/CIP processing routes commonly utilised in Western Australian gold operations.
Key conclusions from this work included:
- Devoid of deleterious elements and hazardous and heavy metals, including Asbestiform Fibres and Naturally Occurring Radioactive Material (NORM)
- Overall gold recoveries were consistently high across all grind sizes tested, ranging from 95.3% to 97.2%.
- Gravity recoverable gold averaged approximately 45%, indicating a significant proportion of gold may be recoverable via gravity concentration prior to cyanidation.
- Leach kinetics were rapid, with test work indicating essentially all cyanide-recoverable gold was extracted within the first 8 hours.
- No preg-robbing or preg-borrowing was observed
- Cyanide and lime consumption remained low throughout the test program, supporting favourable processing characteristics.
- Minimal grind sensitivity was observed, with recoveries remaining robust even at coarser grind sizes.
- No mixing, filtration or settling issues were reported during the grind establishments (60% solids) or leach testwork (45% solids) in site water.
- The P₈₀ 75μm leach residue is not acid mine forming with a Neutralisation Potential Ratio of 15.3²
MT FISHER RC DRILLING UPDATE
RC drilling at the Mt Fisher Project is continuing as part of the Company's broader strategy to expand the current Mineral Resource Estimate and support ongoing development studies across the Mt Fisher-Wagtail project area.
The current 5,000m RC program is targeting extensions to known mineralisation along strike and down plunge of the existing Mt Fisher Mineral Resource, which currently stands at 464kt @ 2.32g/t Au for 35koz Au³.
To date, 17 holes have been completed for a total of 3,068m, with drilling progressing efficiently following mobilisation of Strike Drilling.
All completed drill samples collected to date representing approximately half of the total program will be dispatched to the laboratory this week for analysis, with assay results anticipated within approximately 2-3 weeks of submission.
The Company will continue to provide updates as drilling progresses and analytical results become available.

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 downhole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. | Samples for metallurgical testwork were obtained from Reverse Circulation (RC) drilling previously completed and reported in HTM's ASX announcements dated 12^{th} January and 16th February 2026. |
Metallurgical Composites
A total of 163.78 kg of Reverse Circulation (RC Chip) were delivered to Bureau Veritas (BV) in Canning Vale for metallurgical testwork. These comprised the following intervals, for which the gold grade was previously determined via FA50.
- 25WTRC003 8 = 25.99kg
- 25WTRC008 3-4m = 11.53kg
- 25WTRC0011 36 = 28.36kg
- 25WTRC012 54 = 19.64kg
- 25WTRC023 21-22m = 3.90kg
- 25WTRC025 33-34m = 26.85kg
- 25WTRC030 40-41m = 32.53kg
- 25WTRC030 41-42m = 15.09kg
Each interval was low-temperature dried, crushed to -3.35 mm, homogenised three times through a rotary splitter, split out, and then blended to generate a single Master Composite intended to be representative of future mill feed. Unused crushed samples were placed in sealed and labelled bags. |
| | • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. | • Metallurgical samples for metallurgical testwork were obtained from Reverse Circulation (RC) drilling reported in HTM's ASX announcements dated 12^{th} January and 16th February 2026. |
| | • 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. | • Metallurgical samples for metallurgical testwork were obtained from Reverse Circulation (RC) drilling reported in HTM's ASX announcement dated 12^{th} January and 16th February 2026. |

| Exploration done by other parties | • Acknowledgment and appraisal of exploration by other parties. | Several companies have completed exploration for base metals and gold within the regional Mt Fisher area. These companies include Minops Pty Ltd (1968 to 1971), Tenneco Australia (1971 to 1973), Sundowner (1985 to 1989), ACM Gold Ltd (1988 to 1992), Aztec Mining Company Ltd (1993 to 1994) and Pegasus Gold Australia Pty Ltd (1994 to 1996). |
| Work conducted included aeromagnetic surveys, ground magnetic surveys, regional mapping, rock chip sampling, soil geochemistry (including BLEG and stream sediment sampling) and rotary air blast (RAB) drilling. | ||
| The Mt Fisher deposit was first discovered in 1936 and mining between 1937 and 1949 produced approximately 4,500 tonnes of ore at 28 g/t gold (Powell, 1990). In 1980, a small deposit was defined by percussion drilling around the historical workings. Further drilling from 1984 to 1986 defined a larger deposit to the south of the old workings with Sundowner acquiring a 100% interest in the project in January 1986. | ||
| Sundowner completed a historic estimate of 252,000 tonnes at 5.4 g/t gold to a pit depth of 100 m. | ||
| Following a period of study, a 250,000 tpa carbon-in-pulp treatment plant was built with completion in September 1987. Open pit mining commenced in April 1987 and continued through to September 1988, and processing finished in late November 1988. Total production from the Mt Fisher open pit was reportedly 218,000 tonnes at 4.3 g/t gold. | ||
| Following completion of treatment, the plant was dismantled and moved to Sundowner’s Darlot mine 140 km to the south (Leandri P.S., 1989. Mt Fisher Mt Fisher Mine Eod of Operations Report. March 1989. Sundowner Minerals NL). (Bright, D.V., 1990. Mt Fisher MLS3/127. Annual Technical Report. July 1989 – June 1990. Sundowner Minerals NL). | ||
| Norgold Ltd and BHP Ltd (BHP) conducted gold exploration in the same area in the 1980s and exploration included rock chip sampling and mapping. BHP followed up with RAB and RC drilling reporting several gold anomalies in what was later named the Dam prospect. | ||
| From 1993 to 1997, CRAE completed extensive exploration with work largely focusing on the Dam prospect where gold anomalous was identified over a 7 km by 1 km area. Work completed included |

| RAB and aircore (AC) drilling with a small amount of RC and diamond drilling follow-up. Delta acquired the Project in 1998 and explored it until 2001. They completed additional RAB, AC, RC and diamond drilling. CRAE and Delta defined extensive regolith gold anomalies but were unable to identify any substantial bedrock sources to gold mineralisation. | ||
| From 1996, Cullen Resources NL (Cullen) in joint venture with Newmont Mining Corporation (Newmont) conducted exploration in the Mt Eureka area for gold and were also involved in a nickel joint venture with BHP. | ||
| Avoca Resources Ltd (Avoca) acquired the Mt Fisher Gold Project in 2004 and completed geological mapping and soil and rock chip sampling over much of the tenement area. Drilling was focused on defining further mineralisation along the Dam- Damsel-Dirk gold corridor and extending known mineralisation at Moray Reef, with the internal reporting of Mineral Resources for both the Dam and Moray Reef prospects. From 2004 to 2011, Avoca completed a total of 158 RAB/AC drill holes for 9,111 m and 64 shallow RC drill holes for 5,188 m. | ||
| Geology | • Deposit type, geological setting and style of mineralisation. | • The geological setting is Archean greenstone-hosted gold, with host rocks and structures related to mesothermal orogenic gold mineralisation typical to that found throughout the Yilgarn Craton of Western Australia. |
| Drillhole information | • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drillholes: | |
| • easting and northing of the drillhole collar | ||
| • elevation or RL (Reduced Level – elevation above sea level in metres) of the drillhole collar | ||
| • dip and azimuth of the hole | ||
| • downhole 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. | No information is excluded and full details of the Reverse Circulation (RC) drilling from which metallurgical samples were collected is reported in HTM’s ASX announcements dated 12th January and 16th February 2026. | |
| 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. | • N/A no exploration results reported |

| • The assumptions used for any reporting of metal equivalent values should be clearly stated. | ||
| 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 drillhole angle is known, its nature should be reported. | ||
| • If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (e.g. ‘downhole length, true width not known’). | • N/A no exploration results reported | |
| 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 drillhole collar locations and appropriate sectional views. | Refer to Figures and Tables in the text. |
| 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. | • N/A no exploration results reported |
| 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. | All meaningful and material information has been included in the body of the announcement. |
| 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. | Further work including systematic follow-up metallurgical test work defining metallurgical domains and assessing a scope of work to define representative sampling of the mineralised zone is planned. |
