Deeper Cu-Ag (Sb) Mineralization at Ballywire
Vancouver, Canada, September 22, 2025 - Group Eleven Resources Corp. (TSX-V: ZNG; OTCQB: GRLVF;
FRA: 3GE) (“Group Eleven” or the “Company”) is pleased to announce results from its first hole testing
the ‘Deeper Cu-Ag Target’ at its Ballywire discovery (“Ballywire”) at the 100%-owned PG West Project
(“PG West”), Republic of Ireland.
Highlights:
• 25-3552-40 (filling a 160m gap in previous drilling, while testing the discovery horizon at the base
of the Waulsortian Limestone and 250m below it ) intersected intermittent mineralization over
240m, including:
o Cu-Ag Intercept (hosted within the base of the Waulsortian Limestone)
o 11.4m of 139 g/t Ag and 0.23% Cu (starting from 340.0m downhole), including
o 6.5m of 217 g/t Ag and 0.34% Cu, including
o 0.7m of 654 g/t Ag and 0.96% Cu and
o 0.7m of 1,165 g/t Ag and 1.89% Cu
o Cu-Ag Intercepts (at the ‘Deeper Cu-Ag Target,’ below the Waulsortian Limestone)
o 2.8m of 26 g/t Ag and 0.39% Cu, (from 441.3m downhole), including
o 1.8m of 34 g/t Ag and 0.53% Cu, including
o 0.2m (17cm) of 148 g/t Ag and 2.59% Cu, and
o 17.9m of 10 g/t Ag and 0.37% Cu, (from 516.9m downhole), including
o 4.7m of 13 g/t Ag, 0.71% Cu and 0.09% Sb, including
o 2.6m of 19 g/t Ag, 1.07% Cu and 0.14% Sb
• Results confirm presence of Cu-Ag (Sb) mineralization in the ‘Deeper Cu-Ag Target’ below the base
of the Waulsortian Limestone, in line with Group Eleven’s exploration model
• Two follow-up holes, to the NNW and SSE of the above hole, respectively, are underway
• Cu-Ag (and locally Sb) mineralization consists of chalcopyrite and suspected tennantite -
tetrahedrite occurring as disseminated mineralization and/or within calcite veins; mineralization
appears to be related to a south -dipping fault zone (pierced by today’s drill hole) which is
associated with Zn-Pb-Ag mineralization stratigraphically higher up (at the base of the Waulsortian
Limestone)
“This is the first test of our hypothesized ‘Deeper Cu -Ag Target’ and we are thrilled that it has borne
fruit,” stated Bart Jaworski, CEO. “With a viable new Cu-Ag target below our existing Zn-Pb-Ag horizon,
our exploration potential has essentially doubled. We are gearing up to expand on this deeper
discovery not only up and down dip, but also along our 2.6km -long strike-length of robust zinc
mineralization pierced by drilling to date. As per our nearby geological analogues at Gortdrum,
Denison and Tullacondra, fault -controlled Cu-Ag mineralization tends to strengthen with increased
shattering along the structure. Further drilling at the ‘Deeper Cu-Ag Target’ will aim to identify these
features. With three rigs turning each on excellent targets at Ballywire, a fourth rig likely to be added
soon and a recently bolstered cash position, 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% -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 5 9 holes drilled and reported by Group Eleven to date, including the most
3
recent three holes (25-3552-38, -40 and -41) reported today (see Exhibits 1 to 4). Drilling to date at
Ballywire has pierced robust mineralization over a 2.6km strike-length, along a prospective trend of
over 6km (defined by four regional gravity-high anomalies, only one of which has been systematically
drill tested to date; see Exhibit 4).
Today’s results from hole 25-3552-40 confirm that Cu-Ag mineralization exists below the base of the
Waulsortian Limestone, in line with Group Eleven’s ‘Deeper Cu-Ag Target’ exploration model. Assay
results are summarized in Exhibit 3. In addition to the description above, it is noteworthy that at least
one large (19cm wide) tennantite-tetrahedrite-bearing calcite vein is bedding parallel, whereas other
similar but narrower veins tend to be more irregular in orientation.
Two additional holes have been released today. Holes 25-3552-38 and -41, drilled 1.3km to the NE,
near gravity-high anomaly ‘D’ (see Exhibits 2 and 4), also returned significant results.
Hole 25-3552-41 intersected what is interpreted as oxidized massive sulphide mineralization within a
fault zone. Despite being highly weathered, the interval returned highly anomalous metal
concentrations: (i) 7.9m of 0.74% Zn+Pb (0.57% Zn and 0.17% Pb) an d 7.4 g/t Ag (starting at 229.5m
downhole), including 0.9m of 2.87% Zn+Pb (2.43% Zn and 0.44% Pb) and 35.9 g/t Ag; and (ii) 12.0m
of 0.13% Zn+Pb (0.06% Zn and 0.07% Pb) and 3.3 g/t Ag (starting at 258.2m downhole), including 1.1m
of 0.55% Zn+Pb (0.21% Zn and 0.34% Pb) and 18.6 g/t Ag. These intervals (7.9m and 12.0m) contained
weathered-out cavities totalling 19% and 40% of the ir respective downhole lengths (assumed ‘nil’
grade in the above weighted-average calculations). It is possible that these cavities represent evidence
of preferential weathering due to original high levels of mineralization (e.g. massive sulphide). Hole
25-3552-38 returned trace sphalerite and galena (from approx. 231-244m downhole) near the base of
the Waulsortian Limestone, also suggesting proximity to higher-grade mineralization.
Follow up drilling will resume at this locality once drill permits are received for the adjacent area,
allowing more flexibility to systematically test the entire ‘Anomaly D’ target. This is the Company’s
first test of this target area and given the above results, exploration potential has been confirmed.
Today’s results, combined with: (a) mineralized historic hole 99-3352-5, (b) two shallow historic holes
with abundant calcite (similar to calcite bodies associated with the massive sulphide at the discovery
trend) and (c) the presence of the ‘D’ gravity anomaly itself (see Exhibit 4), add significantly to the
prospectivity of this target.
Overall, three rigs are currently drilling at Ballywire, with a fourth rig expected soon. One rig continues
to drill a fence of holes collared 200m east of hole G11-3552-08 (see Exhibit 2), testing for the easterly
continuation of the mineralized trend. The second and third rigs are drilling along the section of holes
containing G11 -468-01 and 00 -468-5 (see Exhibit 2) to test for a SW continuation of high -grade
mineralization towards gravity-high anomaly ‘B’ . Depending on results, the next fence of drilling
testing the ‘Deeper Cu-Ag Target’ may be from this section. The fourth rig is likely to be geared towards
reconnaissance drilling further outboard of the current mineralized corridor.
Currently, twelve (12) new holes are completed or nearly completed (and in the process of being
logged, sampled and assayed) as shown in Exhibit 2 (specifically, two holes near 25 -3552-40; three
holes near hole G11-3552-19; four holes collared approx. 200m NNW of G11-3552-08; and three holes
on the drill fence hosting G11-468-01).

Eleven staff to ALS Laboratories in Loughrea Co. Galway, Ireland. Sample preparation at the ALS facility
comprises fine crushing 70% < 2mm, ri ffle 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.
