Group Eleven drills 6.2 m of 312 g/t Ag, 0.95% Cu at PG

Mr. Bart Jaworski reports GROUP ELEVEN DRILLS 6.2M OF 312 G/T AG AND 0.95% CU, INCL. 2.8M OF 549 G/T AG AND 1.77% CU IN A 90M STEPOUT, FURTHER SUPPORTING DEEPER CU-AG TARGET AT BALLYWIRE Group Eleven Resources Corp. has released the latest three stepout drill holes from the discovery horizon at its Ballywire discovery at the 100-per-cent-owned PG West project, Republic of Ireland. Drilling at Ballywire's deeper, Cu-Ag (copper-silver) target (100 to 200 metres below discovery horizon) is in progress (to be reported as soon as possible). Highlights: 25-3552-37 (90 m stepout northeast of 25-3552-35, hosting widest intercept to date; announced July 2, 2025) intersected intermittent mineralization over a 185-metre-long interval, including: Cu-Ag intercept (hosted in Ballysteen limestone, beneath Waulsortian limestone): 6.2 m of 312 g/t Ag and 0.95 per cent Cu (starting from 303.9 m down hole), including; 2.8 m of 549 g/t Ag and 1.77 per cent Cu, including; 0.3 m (30 centimetres) of 2,470 g/t Ag and 5.87 per cent Cu. Zn-Pb-Ag (zinc-lead-silver) intercepts (hosted within Waulsortian limestone): 4.9 m of 5.2 per cent Zn plus Pb (4.0 per cent Zn and 1.2 per cent Pb), 45 g/t Ag (starting from 125.9 m), including; 0.1 m (14 cm) of 65.1 per cent Zn plus Pb (46.4 per cent Zn and 18.7 per cent Pb), 654 g/t Ag. 25-3552-36 (90 m stepout southeast of the above hole), intersected intermittent mineralization over a 38 m long interval, including: 2.8 m of 231 g/t Ag and 0.85 per cent Cu, including; 0.2 m (16 cm) of 3,820 g/t Ag and 12.60 per cent Cu (among highest Ag/Cu assays in Ireland). 25-3552-34 (35 m stepout north-northwest of the above hole), intersected intermittent mineralization over 16 m long interval, including 1.9 m of 59 g/t Ag and 0.75 per cent Cu; These results extend the strike length of Ballywire's main discovery corridor by 135 m from 1,300 m to 1,435 m, while further emphasizing Cu-Ag potential at depth; This corridor is hosted within a larger 2.6 km long trend of robust mineralization pierced by drilling to date at Ballywire, along a prospective trend of over six kilometres (defined by four regional gravity-high anomalies, only one of which has been systematically drill tested to date); The company's deeper Cu-Ag target (100 to 200 m below the Zn-Pb-Ag horizon) is currently being drill tested with two holes completed and a third hole in progress; Three rigs are turning at Ballywire with approximately 5,700 m of drilling completed year to date; Group Eleven aims to complete a further approximately 25,000 m of drilling by end of 2026 (fully financed). "Today's results expand our main discovery corridor by 135 m and add to growing evidence suggesting a deeper Cu-Ag horizon one to two hundred metres below Ballywire's current discovery horizon," stated Bart Jaworski, chief executive officer. "This deeper target is currently being drilled, with two holes finished and a third started. We look forward to releasing these results as soon as assays are available. With three rigs turning each on excellent targets at Ballywire, a fourth rig likely to be added soon and a recently announced strengthened cash position now totalling $8.4-million, Group Eleven is poised to keep generating shareholder value through the drill bit for the foreseeable future." Ballywire drill update The Ballywire prospect at the company's 100-per-cent-owned PG West project in Republic of Ireland, represents the most significant mineral discovery in Ireland in over a decade. First announced in September, 2022, the discovery has 56 holes drilled and reported by Group Eleven to date, including the most recent three holes (25-3552-34, -36 and -37) reported today. Today's results add further evidence that the mineralized trend at Ballywire continues farther east toward G11-3552-08. One of the company's three rigs is now drilling a fence of holes collared 200 m east of this hole, testing for the further continuation of the mineralized trend. A second rig is drilling a fence of holes testing for the deeper Cu-Ag target (within the Lower limestone shale) with two holes completed and the third recently started. A third rig is drilling along the section of holes containing G11-468-01 and 00-468-5 to test for a southwest continuation of high-grade mineralization. The company plans to soon add a fourth rig at Ballywire, geared toward reconnaissance drilling further outboard of the current mineralized corridor. Meanwhile, two holes located 1.3 km to the east-northeast (near gravity anomaly D) were recently completed (assays pending), with follow-up drilling planned upon receipt of a second drill permit (recently submitted) which would allow for more flexibility on drill locations further to the northeast. Assays from today's drill holes are summarized above. Mineralization consists predominantly of sphalerite, galena and pyrite, with the Cu-Ag bearing zones also containing chalcopyrite and suspected tennantite-tetrahedrite. Substantial Cu-Ag mineralization in 25-3552-37 is located within the Ballysteen limestone, in contrast to 25-3552-35, where a strong Cu-Ag interval occurs at the base of the Waulsortian limestone. Varying lithologies hosting Cu-Ag mineralization suggest a dynamic and potentially robust mineralizing system with respect to copper and silver. Drilling at Ballywire continues with three rigs. Currently, 12 new holes are completed or near completed (and in the process of being logged, sampled and assayed). Qualified person Technical information in this news release has been approved by Prof. Garth Earls, EurGeol, PGeo, FSEG, geological consultant at IGS (International Geoscience Services) Ltd., and independent qualified person as defined under Canadian National Instrument 43-101. Sampling and analytical procedures All core drilled at Ballywire is NQ (47.6 millimetres) and is cut using a rock saw. Sample intervals vary between 0.10 m to 1.28 m with an average (over 285 samples) of 0.91 m. The half core samples are bagged, labelled and sealed at Group Eleven's core store facility in Limerick, Ireland. Selected sample bags are examined by the qualified person. Transport is via an accredited courier service and/or by Group Eleven staff to ALS Laboratories in Loughrea Co. Galway, Ireland. Sample preparation at the ALS facility comprises fine crushing 70 per cent less than two millimetres, riffle splitter, pulverize up to 250 g 85 per cent less than 75 um. Analytical procedures are 34-element four-acid ICP-AES (codes ME-ICP61 and ME-OG62). Other than paying for a professional analytical service, Group Eleven has no relationship with ALS. Quality assurance/quality control (QA/QC) information Group Eleven inserts certified reference materials as well as blank material, to its sample stream as part of its industry-standard QA/QC program. The QC results have been reviewed by the qualified person, who is satisfied that all the results are within acceptable parameters. The qualified person has validated the sampling and chain of custody protocols used by Group Eleven. About Group Eleven Resources Corp.
