Group Eleven Drills New Mineralized Zone South of Main Discovery
Trend at Ballywire, Returning 7.3m of 5.2% Zn+Pb, 10 g/t Ag (from
326m), Incl. 3.8m of 7.3% Zn+Pb, 14 g/t Ag
Vancouver, Canada, December 02, 2025 - Group Eleven Resources Corp. (TSX-V: ZNG; OTCQB: GRLVF;
FRA: 3GE) (“ Group Eleven” or the “ Company”) is pleased to announce the latest two step-out drill
holes from its Ballywire discovery (“ Ballywire”) at the 100%-owned PG West Project (“PG West”),
Republic of Ireland.
Highlights:
• 25-3552-47 (approx. 100m step-out SSE of 25-3552-40, initial test of the Deeper Cu -Ag target;
announced 22-Sep-25) intersected four zones of mineralization, including:
o New Mineralized Zone (South) - Waulsortian Hosted (starting from 313.1m downhole)
o 20.3m of 2.6% Zn+Pb (1.5% Zn and 1.1% Pb), 6 g/t Ag, including
o 7.3m of 5.2% Zn+Pb (2.5% Zn and 2.7% Pb), 10 g/t Ag, including
o 3.8m of 7.3% Zn+Pb (3.7% Zn and 3.6% Pb), 14 g/t Ag, including
o 1.9m of 10.7% Zn+Pb (5.7% Zn and 5.0% Pb), 19 g/t Ag
o New Mineralized Zone (South) - Base of Waulsortian (starting from 355.9m downhole)
o 2.6m of 2.7% Zn+Pb (0.1% Zn and 2.5% Pb) and 19 g/t Ag, including
o 0.8m of 6.7% Zn+Pb (0.3% Zn and 6.5% Pb) and 37 g/t Ag
o Deeper Cu-Ag Zone (starting from 490.7m downhole)
o 11.3m of 0.26% Cu and 8 g/t Ag, including
o 4.7m of 0.46% Cu and 14 g/t Ag, including
o 1.8m of 0.83% Cu and 24 g/t Ag
o Deeper Cu-Ag Zone (starting from 616.6m downhole)
o 9.4m of 0.25% Cu and 7 g/t Ag, including
o 3.7m of 0.32% Cu and 8 g/t Ag, including
o 0.8m of 0.62% Cu and 16 g/t Ag
“Today’s re sults represent a positive surprise given we were not expecting robust Zn -Pb-Ag
mineralization south of the main discovery trend at this particular location,” stated Bart Jaworski, CEO.
“In addition to successfully extending significant Deeper Cu-Ag mineralization down dip by over 200m
from previous drilling , today’s hole intersected strong Zn -Pb-Ag mineralization in a new part of the
discovery. Long theorized, new zones of mineralization parallel to the main discovery trend at
Ballywire were evidenced this September by hole 25-3552-44 which discovered a new Cu-Ag bearing
feeder structure to the north of the main discovery. Today’s results show a similar situation , but to
the south, enhancing the potential for at least two additional mineralized zones. If borne out, this
greatly expands Ballywire’s tonnage potential.”
“Driven by new zones of mineralization, growing momentum at our Deeper Cu -Ag zone and the fact
that the majority of our 6km long prospective trend is yet to be drilled, Ballywire’s exploration upside
continues to ramp up. With a robust treasury and our most ambitious drilling campaign to date — four
rigs turning in Ireland — we are poised to continue unlocking Ballywire’s full potential over the coming
months.”

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 64 holes drilled and reported by Group Eleven to date, including the most
recent two holes (25-3552-45 and -47) reported today (see Exhibits 1 to 6).
Assays from today’s drill holes are summarized above and below (and in Exhibits 4 and 5).
Mineralization consists predominantly of sphalerite, galena and pyrite, with the Cu-Ag bearing zones
also containing chalcopyrite and suspected tennantite-tetrahedrite.
In addition to results from 25 -3552-47, described above, hole 25 -3552-45 intersected two zones of
significant mineralization along a fault structure (see Exhibits 3 and 5 ). Strong exploration upside
remains further to the NNW and SSE along this section.

Notes to Exhibit 7: (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 esti mate 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 Prop erty’ 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 ke y 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 res ources. ‘Rathdowney Trend’ is the south -
westerly projection of the Rathdowney Trend, hosting the historic Lisheen and Galmoy mines.

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.
