NewsfileVancouver, British Columbia--(Newsfile Corp. - June 11, 2026) - Group Eleven Resources Corp. (TSXV: ZNG) (OTCQB: GRLVF) (FSE: 3GE) ("Group Eleven" or the "Company") is pleased to announce new assay results from drill hole 26-3552-57 at its Ballywire discovery ("Ballywire") at the 100%-owned PG West Project ("PG West"), Republic of Ireland.Highlights:26-3552-57 - Drilled 80m SW of 25-3552-51 (which intersected 52.3m of 10.3% Zn+Pb, 330 g/t Ag and 0.40% Cu; announced 25-Feb-2026):62.5m of 5.6% Zn+Pb and 25 g/t Ag (at the base of the Waulsortian Limestone; starting from 329m downhole; announced 28-May-2026), including 11.8m of 13.4% Zn+Pb and 45 g/t AgToday announced new assays showing nine (9) zones of mineralization from the Deeper Cu-Ag target (starting from 400m downhole), with highlights as follows:14.9m of 53 g/t Ag and 0.08% Cu, incl.2.8m of 143 g/t Ag, 0.31% Cu, incl.0.9m of 371 g/t Ag, 0.82% Cu and 0.10% Sb; and6.6m of 83 g/t Ag, 1.60% Cu and 0.19% Sb, incl.1.0m of 279 g/t Ag, 5.62% Cu and 0.78% Sb and2.8m of 110 g/t Ag, 5.09% Cu and 0.44% Sb, incl.0.6m of 506 g/t Ag, 23.60% Cu and 2.04% SbFour rigs continue to be active at Ballywire with an additional rig active at the adjacent 77.64%-interest Stonepark Project"Today's 23.60% Cu result represents some of the highest copper grades attained by any operator over the last 60 years of modern mineral exploration history in Ireland," stated Bart Jaworski, CEO. "This high-grade intercept, accompanied by 506 g/t Ag and 2.04% Sb, is one of nine zones of mineralization, some of which also attained grades of up to 5.62% Cu, 371 g/t Ag and 0.78% Sb.""Today's results also represent the seventh drill hole and the fourth drill fence at Ballywire to intersect Deeper Cu-Ag mineralization thus far. Not including the 720m step-out announced in our last news release (28-May-2026) showing what appears to be the beginning of new zone of Deeper Cu-Ag mineralization, the three highest grading Cu-Ag drill fences drilled thus far now represent an impressive strike-length of 430m. This new evidence provides us with growing conviction that Deeper Cu-Ag mineralization may extend across the entire Ballywire Zn-Pb-Ag discovery, which is currently known to span approx. 3.2km along prospective trend of 6km. With a robust treasury and our most ambitious drill campaign to date - bolstered by our $12m financing in March, allowing go-forward funded drilling to increase from 20,000m to approx. 67,000-75,000m - we are poised to continue unlocking this discovery's full potential."Exhibit 1.

https://images.newsfilecorp.com/files/5685/301020_7ec66efd04d34ace_004full.jpgMineralization reported today consists predominantly of Cu-Ag bearing zones containing chalcopyrite and suspected tennantite-tetrahedrite, with minor sphalerite, galena and pyrite. Four rigs continue to be actively drilling at Ballywire. Currently, fifteen (15) new holes are completed (and in the process of being logged, sampled and assayed) or in the process of being drilled. These are shown in Exhibits 1, 2 and 5.Given the Company's recent C$12.0m financing (closed 11-Mar-2026), the go-forward funded drill program has increased from 20,000m to between 67,000m and 75,000m (subject to detailed planning), largely earmarked for Ballywire, with the remainder at Stonepark.Notes to Exhibit 6: (a) Pallas Green MRE is owned by Glencore (see Glencore's Resources and Reserves Report dated December 31, 2025); (b) Stonepark MRE: see the 'NI 43-101 Independent Report on the Zinc-Lead Exploration Project at Stonepark, County Limerick, Ireland', by Gordon, Kelly and van Lente, with an effective date of April 26, 2018, as found on SEDAR+; and (c) the historic estimate at Denison was reported by Westland Exploration Limited in 'Report on Prospecting Licence 464' by Dermot Hughes dated May, 1988; the historic estimate at Gortdrum was reported in 'The Geology and Genesis of the Gortdrum Cu-Ag-Hg Orebody' by G.M. Steed dated 1986; and the historic estimate at Tullacondra was first reported by Munster Base Metals Ltd in 'Report on Mallow Property' by David Wilbur, dated December 1973; and later summarized in 'Cu-Ag Mineralization at Tullacondra, Mallow, Co. Cork' by Wilbur and Carter in 1986; the above three historic estimates have not been verified as current mineral resources; none of the key assumptions, parameters and methods used to prepare the historic estimates were reported and no resource categories were used; significant data compilation, re-drilling and data verification may be required by a Qualified Person before the historic estimates can be verified and upgraded to be compliant with current NI 43-101 standards; a Qualified Person has not done sufficient work to classify them as a current mineral resource and the Company is not treating the historic estimates as current mineral resources. 'Rathdowney Trend' is the south-westerly projection of the Rathdowney Trend, hosting the historic Lisheen and Galmoy mines.Exhibit 6.

"With significant Cu-Ag bearing fault structures now pierced by five holes along two drill fences located 350m apart, we have increasing conviction that Deeper Cu-Ag mineralization may extend across the entire discovery to date. Extending the mineralized strike length of the discovery by 600m to 3.2km bodes well for our ongoing drilling along our 6km prospective trend. Today's impressive Waulsortian-hosted mineralization is also very encouraging. With a robust treasury and our most ambitious drill campaign to date – recently bolstered by our $12m financing allowing go-forward funded drilling to increase from 20,000m to approx. 67,000-75,000m, we are poised to continue unlocking this discovery's full potential."Exhibit 1.

First announced in Sept-2022, the discovery has 77 holes drilled and reported by Group Eleven to date, including the most recent two new holes (25-3552-53 and -52) reported today. Today's results from 25-3552-51 are in addition to partial assays announced on 19-Jan-2026 and 25-Feb-2026. All of today's results are summarized above and below (see Exhibits 1 to 5).Mineralization reported today consists predominantly of sphalerite, galena and pyrite, with Cu-Ag bearing zones also containing chalcopyrite and locally, suspected tennantite-tetrahedrite. Hole 25-3552-52 was a significant step-out hole drilled approx. 350m ENE of its nearest drill hole (see Exhibit 2), on the far east portion of the Ballywire discovery. This hole returned robust mineralization totalling 2.8m of 3.3% Zn+Pb (3.2% Zn and 0.1% Pb) and 16 g/t Ag, including 1.0m of 7.7% Zn+Pb (7.4% Zn and 0.3% Pb) and 38 g/t Ag (see Exhibits 2 and 3). Relative to the nearest significantly mineralized hole (G11-3552-08), this hole expands the strike-length of mineralization intercepted to date at Ballywire by approx. 600m from 2.6km to 3.2km (see Exhibit 2).Exhibit 4.

Currently, eleven (11) new holes are completed (and in the process of being logged, sampled and assayed) or in the process of being drilled. These are shown in Exhibits 2 and 5, including: (i) three holes collared on a fence at the SW extent of the discovery; (ii) two holes stepping out approx. 100m SW from today's drill fence; (iii) three holes drilled in a fan pattern immediately SW of G11-3552-08; (iv) one hole testing 300m NE of today's 25-3552-52, testing the 'D' gravity-high anomaly; (v) one hole testing for parallel zones of mineralization approx. 100m NNE of G11-3552-08 and (vi) one hole testing the 'A' gravity-high anomaly.Exhibit 6.

Steed dated 1986; and the historic estimate at Tullacondra was first reported by Munster Base Metals Ltd in 'Report on Mallow Property' by David Wilbur, dated December 1973; and later summarized in 'Cu-Ag Mineralization at Tullacondra, Mallow, Co. Cork' by Wilbur and Carter in 1986; the above three historic estimates have not been verified as current mineral resources; none of the key assumptions, parameters and methods used to prepare the historic estimates were reported and no resource categories were used; significant data compilation, re-drilling and data verification may be required by a Qualified Person before the historic estimates can be verified and upgraded to be compliant with current NI 43-101 standards; a Qualified Person has not done sufficient work to classify them as a current mineral resource and the Company is not treating the historic estimates as current mineral resources. 'Rathdowney Trend' is the south-westerly projection of the Rathdowney Trend, hosting the historic Lisheen and Galmoy mines.Stonepark UpdateAt the Stonepark Project (77.64% Group Eleven, 22.36% Arkle Resources plc), located contiguous to the PG West Project, one hole (25-449-04) was drilled late last year at the Bruff prospect (see background information on Bruff and Kilteely prospects in news release dated 16-Jun-2025). Drilled to a depth of 480m, this hole tested the base of the Waulsortian Limestone near a suspected fault structure. A significant zone of blocky calcite was intersected from 194m to 200m with a brecciated lower contact, while minor disseminated pyrite was observed in the 10m above the base of the Waulsortian Limestone at 445m. While assays (recently received) did not return anomalous grades, the hole is encouraging as it shows a geological environment prospective for Irish-type zinc mineralization (i.e. calcite zones, brecciation and sulphides). Building on the above geological observations, the Company is mobilizing a rig to Stonepark this week, supplementing the four rigs operating at Ballywire. A four-hole drill program totalling 2,700m is planned, comprising: one hole at the Stonepark deposit testing beneath known Zn-Pb mineralization for possible Cu mineralization; one hole at the Kilteely prospect; and two holes at or near the Bruff prospect. Arkle Resources has elected not to participate in funding this program, with its interest in the Project estimated to decrease from 22.36% to 21.38% (subject to cost actuals after fieldwork completion). The Company aims to provide further information on this program later this year. Qualified PersonTechnical information in this news release has been approved by Professor Garth Earls, Eur Geol, P.Geo, FSEG, geological consultant at IGS (International Geoscience Services) Limited, and independent 'Qualified Person' as defined under Canadian National Instrument 43-101.Sampling and Analytical ProceduresAll core drilled at Ballywire is NQ (47.6mm) and is cut using a rock saw. Sample intervals vary between 0.20m to 1.45m with an average (over 326 samples) of 0.93m. 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% < 2mm, riffle splitter, pulverise up to 250g 85% < 75um. 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) InformationGroup Eleven inserts certified reference materials ("CRMs" or "Standards") as well as blank material, to its sample stream as part of its industry-standard QA/QC programme.
