Vancouver, Canada, June 11, 2026 - Group Eleven Resources Corp. (TSX-V: ZNG; OTCQB: GRLVF; FRA:
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 Ag
• Today 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; and
• 6.6m 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 and
• 2.8m 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% Sb
• Four 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.”

Ballywire Drill Update
The Ballywire prospect at the Company’s 100% -owned PG West Project in Republic of Ireland,
represents the most significant mineral discovery in Ireland in over a decade. First announced in Sept-
2022, the discovery has 79 holes drilled and reported by Group Eleven to date, including today’s
results from 2 6-3552-57 which are in addition to partial assays announced on 28-May-2026. All of
today’s results are summarized above and below (see Exhibits 1 to 5).

Exhibit 5. Regional Gravity Map Showing 6km Long Prospective Trend at Ballywire
Note: Of the four gravity-high anomalies above, only the ‘C’ anomaly has been systematically drilled to date
Mineralization 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 resour ce categories were used; significant data
5
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.

independent ‘Qualified Person’ as defined under Canadian National Instrument 43-101.
Sampling and Analytical Procedures
All core drilled at Ballywire is NQ (47.6mm) and is cut using a rock saw. Sample intervals vary between
0.34m to 0.99m with an average (over 157 samples) of 0.92m. 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, r iffle 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) Information
Group 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. T he 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. Drill data (dip, azimuth and depth) for today’s release will be posted on Group Eleven’s
website in due course.
