Vertex Minerals Ltd Quarterly Activities Report - June 2026 Page 2 of 26 Overview Vertex Minerals Limited (“Vertex” or “the Company”) is pleased to present its Quarterly Activities Report for the quarter ended 30 June 2026. The June 2026 quarter was a period of underground development and decline rehabilitation for Vertex, alongside a number of significant corporate developments. Consistent with the current Reward mine plan1, the Company prioritised the rehabilitation of Declines 1, 2 and 3 to open access to the lower levels, from which bottom-up long hole stoping is scheduled to commence in October 2026. On the corporate front, the Company appointed Bruce McInnes as Executive Chairman, settled the $9 million convertible loan facility, and after quarter end, launched a share purchase plan. Gold production during the June 2026 quarter was lower than the March 2026 quarter, consistent with the current mine plan, as ore feed was sourced predominantly from development material and airleg stope ore, ahead of the commencement of long hole stoping. The quarterly production information is shown as follows: Quarter Ended (unaudited) Gold Produced (oz) Gold Sold (oz) December 2025 123 118 March 2026 284 245 June 2026 195 217 Table 1: Gold production results from the Reward Mine, per quarter, rounded to the nearest ounce. Vertex Minerals Executive Chairman, Bruce McInnes, commented: “Since joining Vertex as Executive Chairman during the quarter, my focus has been on supporting the team as the Reward Gold Mine works through a development-intensive phase of its transition to a mechanised, long hole stoping operation. The quarter was, by design, targeted towards underground development and rehabilitation rather than production, as the Company advances the declines to the lower levels ahead of the planned commencement of long hole stoping in October 2026." "During the quarter the Company continued to open and advance multiple mining fronts, with airleg stoping progressing on the Paxtons Reef across the 671 and 677 levels, Decline 3 flatback Lift 2 completed, and the second Aramine tele-remote loader coming into operation." 1 (ASX:VTX) announcement dated 3 January 2024, ‘Reward Gold Project PFS demonstrates strong economics and a robust base for future growth’. Vertex Minerals Ltd Quarterly Activities Report - June 2026 Page 3 of 26 "The rehabilitation of the declines remains the critical path to production. The underground workings have been submerged for approximately 14 years and, when dewatered, required extensive ground support. The team continues to prioritise rehabilitation of Declines 1, 2 and 3, which will progressively deliver higher-grade ore to the plant as stoping ramps up." "On the corporate front, the $9 million convertible loan facility announced in March was completed during the quarter, and after quarter end, the Company launched a Share Purchase Plan. These initiatives strengthen Vertex’s balance sheet and support the continued development of the Reward Gold Mine." "Looking ahead, the focus is on completing decline rehabilitation, commencing the first trial of long hole open stoping and progressing the updated Mineral Resource estimate. We also await the determination of our development consent modification from the Bathurst regional council, which is expected in mid-August 2026. I look forward to working with the other board members and the team to deliver the next phase of Vertex's growth." Operations Reward Gold Mine (Hill End, NSW) Background The Hill End Gold Project is located in the Central Tablelands of New South Wales, approximately 50 kilometres south of Mudgee, within the highly prospective Eastern Lachlan Fold Belt (Image 1). Vertex holds 155 km² of tenure across five exploration licences, one gold lease (GL 5846) and ten mining leases (ML 49, 50, 315, 316, 317, 913, 914, 915, 1116 and 1541). The district has a rich gold mining history, with more than four million ounces historically produced. Vertex’s ground position spans the Hill End corridor and includes several historic high-grade mines. Mineralisation within the district is hosted within multiple laminated quartz vein systems, with the Lady Belmore Reef and the adjacent Mica vein systems forming the principal structures currently being developed. The cornerstone of the Company’s development strategy is the Reward Gold Mine (Image 2), a high-grade underground operation accessed via the existing 640 Level portal. The Reward Gold Mine benefits from substantial existing infrastructure - a permitted processing plant site, established portal, ventilation and services, permitted residue storage, and road access. Together, these features provide a strong platform for Vertex’s transition from explorer to producer.

Ore feed during the quarter was predominantly sourced from development material, consistent with the current mine plan. Development activities During the quarter, development activities focused on the rehabilitation of Declines 1, 2 and 3, which will form the basis for production at the Reward Gold Mine over the coming years. Development advanced 78 metres in April, 88 metres in May and 57 metres in June. In addition, 42 metres (April), 33 metres (May) and 52 metres (June) of decline rehabilitation was completed, comprising cutting, meshing and bolting of the decline backs and walls. The mine also continued to advance airleg development and stoping. Airleg stoping targeting the high-grade Paxtons Reef advanced across the 671 and 677 levels, with stopes identified both to the north and south of the Reward shaft. The expansion of available mining fronts remains a critical component of the Company's strategy to increase overall production rates and reduce reliance on any single working area. During the quarter, development also advanced on the remaining cuts required to break through at the 677 Paxtons South Block and the 677 & 683 Paxtons North Block, with a potential extension identified at the North Block. As a result of the progress made during the quarter, Decline 1 had approximately 100 metres of rehabilitation remaining at quarter end, and Decline 2 reached full rehabilitation (Image 3(a)). The second lift of the Decline 3 mining front was also completed, including rehabilitation and backfilling. The area is now being prepared for cable bolting, with an air- leg slot rise to be mined on the Mica 1 lens only, ahead of the first trial of long hole open stoping. A modified jumbo will carry out the long hole drilling in the interim, until the dedicated Muki long hole rig arrives (expected in October 2026) (Image 3(b)).

Image 3b: Planned mining activity for July, including airleg stoping of the 671 and 677 levels. Operational and Strategic Changes During the quarter, Vertex continued to implement a series of operational initiatives at the Reward Gold Mine that are designed to increase development grades, expand mining fronts and progress the transition to mechanised long hole stoping. Vertex Minerals Ltd Quarterly Activities Report - June 2026 Page 7 of 26 The following key initiatives were progressed during the quarter: • Increase to monthly development As part of its ongoing strategy to increase development grades and reduce dilution when mining the narrow, high-grade gold veins, the Company reduced development drive dimensions at the Reward Gold Mine by approximately 20% during the quarter. By adjusting the drive profile to more closely match the width of the veins, less waste material is excavated per metre of advance, so that the material mined more accurately reflects the true grade of the vein. To support the narrower profile, new Muki jumbo rails were delivered during the quarter and are being fitted to the Company's existing Epiroc T1D and Atlas Copco H104 jumbo drills, with fitting to be completed in July 2026 by a specialist fitter from Peru. Permitted firing times were also modified during the quarter, with blasting moved to the end of shift to provide additional available mining time per shift. Fleet capacity at the Reward Gold Mine was also increased to match the growing number of active mining fronts. The second Aramine tele-remote loader arrived on site during the quarter and is fully operational, and a second Bird underground truck is in transit from South Africa, with delivery expected in late August 2026 to remove haulage bottlenecks. Vertex has also ordered a Muki LHBP narrow vein long hole production drilling rig from Resemin, which will provide accurate blast hole drilling within the new smaller drive dimensions and target stoping widths of approximately 1.2 metres, similar to the current airleg mining. Construction of the rig is scheduled for completion in mid- September 2026, and it remains on track to be on site and available for stoping in October 2026 (Image 4). Image 4: Muki Production Drilling Rig, to be used at the Reward Gold Mine Vertex Minerals Ltd Quarterly Activities Report - June 2026 Page 8 of 26 • Increasing Mining Grade Alterations to the mine schedule continued to focus on improving development grades. The Company advanced its airleg mining strategy during the quarter, operating multiple airleggers targeting high-grade gold stopes on the Paxtons Reef across the 671 and 677 levels, both north and south of the Reward shaft. A further high-grade airleg stope on the 677 sublevel is scheduled to come into production in July 2026, adding another high-grade mining front and contributing higher-grade ore to the processing plant. Airleg activities experienced some delays during June 2026 while platforms were established around scrapers and passes on level; however, both airleg production stope fronts were subsequently brought into full production in early July 2026. • Processing Plant Optimisation The gravity-only processing plant continued to operate on underground ore during the quarter. No material changes to the processing flowsheet occurred during the June 2026 quarter. • Mine Planning and Scheduling Improvements The Company's mine planning team continued to optimise development, mine grades, mining techniques, backfill strategies and production scheduling, incorporating the new structural geology model completed during the quarter. Scheduling improvements continued during the quarter, increasing the number of production mining fronts available in the Life of Mine plan and providing greater operational flexibility. These included a centre retreat mining sequence accessed from Decline 2 on the 600 Level, which establishes access for mining below the current known resource. • Work and Blasting Hours - Development Application Modification The current restrictions around work hours and blasting times have been identified as significant factors limiting available underground working hours at the Reward Gold Mine. The Company's DA modification to vary the working and blasting hours for the Reward Gold Mine, submitted during the March 2026 quarter, remains before Bathurst Regional Council, with a determination expected in mid-August 2026. Approval of this DA modification would materially increase available underground mining time at the Reward Gold Mine and accelerate the production ramp-up trajectory toward the mine's nameplate capacity. Processing and Gold Production Gold production at the Reward Gold Mine was lower during the June 2026 quarter than prior quarters, which is consistent with the current mine plan as ore feed was sourced predominantly from development ore and airleg stope ore, ahead of the commencement of long hole stoping. Vertex Minerals Ltd Quarterly Activities Report - June 2026 Page 9 of 26 The following table summarises gold production and sales performance for the June 2026 quarter: Month (unaudited) Gold Produced (oz) Gold Sold (oz) Gross Revenue ($) Gold on Hand (oz) April 2026 39 53 354,912 29 May 2026 63 51 326,136 41 June 2026 93 113 674,151 21 QUARTER TOTAL 195 217 1,355,199 Table 2: Gold production results from the Reward Mine during the June 2026 quarter, by month April 2026 During April 2026, all ore processed was sourced from development ore, with no airleg or jumbo flatback stopes online during the month, consistent with the current mine plan. Production was therefore lower than March, as expected. Gold sold in April 2026 was 53 oz, with 29 oz of gold on hand and available for sale at the end of the month. Development remained the focus during the month, with 78 metres of advance development and a further 42 metres of development rehabilitation completed. Decline 3 flatback Lift 2 commenced, with ore to begin processing in July (Image 5). Development of two new airleg stopes targeting the high-grade Paxtons Reef on the 671 and 677 levels also commenced during April, and the second Aramine tele-remote loader arrived on site and was commissioned underground. Image 5: Long section through the Decline 3 flatbacks Vertex Minerals Ltd Quarterly Activities Report - June 2026 Page 10 of 26 May 2026 Gold sold in May 2026 was 51 oz, with 41 oz of gold on hand and available for sale at the end of the month. Production during May was lower, as expected under the current mine plan, with higher-grade ore from airleg stopes beginning to be processed towards the end of the month. Development remained the focus during May, with 88 metres of advance development and a further 33 metres of development rehabilitation completed. Rehabilitation of the declines continued, with Decline 1 having 115 metres of rehabilitation remaining, Decline 2 having approximately 50 metres remaining, and Decline 3 having approximately 6 metres of flatback development remaining, before the first full trial of long hole open stoping could commence. June 2026 Production during June 2026 continued to be sourced from development ore and airleg stope ore, reflecting the planned emphasis on decline rehabilitation and development ahead of the commencement of long hole stoping. Gold produced in June 2026 was 93 oz and gold sold was 113 oz, a monthly record for Vertex, generating gross revenue of approximately $674,151 for the month. Mill recovery improved to 82% during June 2026, which was a positive result given that the plant continued to process lower-grade development ore. Processing and Underground Mining The Reward gravity-only processing plant continued to operate on underground ore throughout the June 2026 quarter, with feed comprising predominantly lower-grade development material. While the plant is capable of gold recoveries of up to 95%, recoveries during the quarter reflected the lower-grade feed profile. Daily operational time at the plant was maintained at approximately 11 hours, following the extension from 9 to 11 hours implemented in the prior quarter through engineered start-up and shutdown procedures. This continues to support greater utilisation of plant capacity. Plant Operational Hours During the March 2026 quarter, the Company submitted an application to Bathurst Regional Council to vary the approved working and blasting hours at the Reward Gold Mine, which if approved would materially increase available underground mining time. During the June 2026 quarter, there was no change to the status of the application, which remained under assessment by Bathurst Regional Council. Vertex Minerals Ltd Quarterly Activities Report - June 2026 Page 11 of 26 Hargraves Gold Project (Hill End, NSW) Background The Hargraves Project is located approximately 35 kilometres north of Hill End in the Central Tablelands of New South Wales, within the highly prospective Eastern Lachlan Fold Belt. The project comprises two granted exploration licences (EL 6996 and EL 9485) covering the historical Hargraves Goldfield. The area has a rich mining history, with more than 1.4 million ounces of gold historically produced from reef and alluvial workings. Hargraves hosts a JORC-compliant Mineral Resource of 2.3 million tonnes at 2.4 g/t Au for 178,000 ounces (refer page 18 of this report). Its proximity to Hill End positions Hargraves as a logical potential satellite ore source, supporting the Company’s strategy of developing Hill End as a centralised processing hub. Work completed during the quarter No work was completed during the quarter for the Hargraves Gold Project. Taylor Rock Project Background The Taylor Rock Project (E63/2058) lies on the southeastern margin of the Lake Johnston Greenstone Belt in Western Australia, approximately 190 km southwest of Kalgoorlie. The geological setting is highly prospective, with historic drilling identifying pegmatite swarms that may host lithium-bearing spodumene, as well as nickel sulphide potential from past exploration campaigns by Norilsk Nickel. Image 6: Map of the Taylor Rock Project Work completed during the quarter No work was completed during the quarter for the Taylor Rock Project. Vertex Minerals Ltd Quarterly Activities Report - June 2026 Page 12 of 26 Pride of Elvire Project Background The Pride of Elvire Project (E77/2651, ~51 km²) is located in the Mt.
