Group Eleven Announces $2.2 million in Early Warrant and Option

Exercises and Provides Update on Carrickittle West ‘Pallas Green

Lookalike’ Target

Vancouver, Canada, June 16, 2025 - Group Eleven Resources Corp. (TSX-V: ZNG; OTCQB: GRLVF; FRA:

3GE) (“Group Eleven” or the “ Company”) is pleased to announce funding from early warrant and

option exercise and provide an update on the Company’s Carrickittle West prospect, spanning 77.64%-

owned Stonepark Project (“Stonepark”) and 100%-owned PG West Project (“PG West”), Republic of

Ireland. Drilling continues with three rigs at the Ballywire discovery (“Ballywire”) at PG West.

Highlights:

• Early warrant and option exercises totalling proceeds of $2,206,752 received since C$2.5 mln

placement closed Feb-28-2025 (including $1,852,902 since publication of Q1 2025 financials)

• Extra proceeds provide flexibility to ramp-up 2025 drilling and/or extend drilling well into 2026

• At Carrickittle West, four holes were completed late 2024 and early 2025 (three holes located at

Stonepark and one hole located at PG West)

• Most significant target to emerge from this drilling is the Kilteely Prospect (large breccia body

spanning at least 1.5km in strike)

o G11-2840-30 (365m step-out) intersected numerous zones of weak breccia with pyrite

over narrow intervals throughout the Waulsortian Limestone; some breccias returned

anomalous Zn-Pb and Cu levels, with the base of the Waulsortian Limestone (key target

horizon) hosting minor disseminated pyrite and trace sphalerite

o Several occurrences of trace sphalerite are present in the hole, potentially suggesting

increasing proximity to stronger mineralization relative to previous drilling at Kilteely

• Three other target areas have also emerged at Carrickittle West, including the Bruff Prospect

o G11-449-03 (315m step -out), targeting part of the >50km long Coonagh Castle Fault ,

intersected extensively dolomitized Waulsortian Limestone and a very prominent zone of

calcite extending over 35m (from 294m), similar to Ballywire

o Base of Waulsortian is highly dolomitized over a 25m interval with similarities to ‘ fault

dolomite’ observed at Ballywire, which i ndicates intense hydrothermal fluid flow and

close proximity to a major fault; follow up drilling is highly warranted

“Carrickittle West continues to be one the best drill target s in Ireland,” stated Bart Jaworski, CEO.

“Being within only a few kilometres of 45 and 5 million tonnes of mineralization from Glencore’s Pallas

Green1 and our Stonepark 2 deposits, respectively, this prospect has a real chance at hosting the

southern half ‘mirror-image’ of the mineralizing system operating at the northern side of the Limerick

Volcanic Complex. Today’s drill results demonstrate the presence of key attributes – brecciation,

faulting, hydrothermal fluids and significant pyrite. The fact we’re also starting to pick up sphalerite

locally in some of the drilling suggests we may be getting close to the high-grade. We look forward to

follow-up drilling. Meanwhile, three rigs are turning at our Ballywire discovery and we anticipate the

next drill results over the coming few weeks.”

1 Pallas Green MRE is 45.4 million tonnes of 8.4% Zn+Pb (7.2% Zn + 1.2% Pb), Inferred (Glencore, Dec -31-2024)

2 Stonepark MRE is 5.1 million tonnes of 11.3% Zn+Pb (8.7% Zn and 2.6% Pb), Inferred (Apr -17-2018)

Ballywire Drill Update

Drilling at Ballywire continues with three rigs. Currently, nine (9) new holes are completed (and in the

process of being logged, sampled and assayed). Seven of these holes are shown in Exhibit 1, with two

other holes near gravity-high anomaly ‘D’ (located 1.3km to the ENE). Additional funding described

above, nearly equal to Group Eleven’s most recent private placement, increases the Company’s cash

to approx. C$4.3 mln (as at 13-Jun-2025). This strengthened financial position provides Group Eleven

flexibility to either ramp-up drilling in 2025 and/or extend its runway for drilling well into 2026.

New Step-Out Holes at Carrickittle West Target Area

The Carrickittle West target area spans the Company’s 77.64%-owned Stonepark Project and 100% -

owned PG West Project . In addition to holes G11 -2840-30 and G11-449-03 summarized above (and

shown in Exhibits 2-4), the following is a summary of the remaining two holes drilled (see Exhibit 2).

• G11-450-04 (570m step-out from previous drilling in area)

o Planned to test the hanging wall (north side) of the Kilteely Fault but intersected the

footwall (south side) instead

o The base of the Waulsortian Limestone comprises a fine -grained dolomite, similar to

Ballywire, with a series of breccias similar to black matrix breccia (“BMB”, host alteration

to Zn-Pb mineralization at Lisheen, Galmoy, Silvermines and Pallas Green)

o Pyrite is extensive in breccias with anomalous levels of base metals

o Colloform semi-massive pyrite is present from 265.27m to 265.73m and at 267.5m

o Future drilling will target base of Waulsortian on the hanging wall of the Kilteely Fault

• G11-2531-02 (710m step-out from previous drilling in area)

o Planned to test the hanging wall of Coonagh Castle Fault, but intersected the footwall

instead

o Waulsortian is dolomitized throughout and contains extensive zones of pyritic

brecciation at the top and base of the Waulsortian Limestone

o Breccias have vague similarity to Stonepark-style BMB

A follow up drill program is being designed, with one hole planned at Stonepark later this year and the

remainder of holes to be drilled in 2026.

Notes to Exhibit 5: (a) Pallas Green MRE is owned by Glencore (see Glencore’s Resources and Reserves

Report dated December 31, 2024); (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.

Sampling and Analytical Procedures

All core drilled at Carrickittle West is NQ (47.6mm) and is cut using a rock saw. Sample intervals vary

between 0.32m to 1. 4m with the majority of samples in the 0. 80m to 1.00m range. 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) 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.
