Group Eleven Resources Corp. (TSX-V: ZNG) (OTCQB: GRLVF) (FSE: 3GE) is pleased to announce additional assays from 25-3552-51 (initial assays announced 19-Jan-2026), plus results from two other holes drilled at its Ballywire discovery at the 100%-owned PG West Project, Republic of Ireland.

Highlights:

• 25-3552-51 – Extends previous interval announced on 19-Jan-2026, totalling 29.9m of 15.3% Zn+Pb, 552 g/t Ag and 0.67% Cu (from 338m downhole, at base of Waulsortian Limestone), to:
  • 52.3m of 10.3% Zn+Pb (5.8% Zn and 4.5% Pb), 330 g/t Ag, 0.40% Cu, including today’s new assays from immediately below base of Waulsortian Limestone:
  • 22.4m of 3.8% Zn+Pb (0.6% Zn and 3.2% Pb), 33 g/t Ag (from 368m), incl.
    • 16.8m of 4.8% Zn+Pb (0.8% Zn and 4.0% Pb), 42 g/t Ag, incl.
    • 7.5m of 8.1% Zn+Pb (0.9% Zn and 7.2% Pb), 61 g/t Ag, incl.
    • 2.8m of 10.6% Zn+Pb (0.9% Zn and 9.7% Pb), 99 g/t Ag, 0.15% Cu
• Deeper in the same hole, three new and significant Cu-Ag zones encountered, representing 350m step-out SW of previous test of Deeper Cu-Ag target:
  • 8.4m of 5.7% Zn+Pb (0.1% Zn and 5.6% Pb), 132 g/t Ag, 0.52% Cu (from 401m), incl.
    • 3.7m of 2.7% Zn+Pb (0.1% Zn and 2.5% Pb), 225 g/t Ag, 1.03% Cu, 0.07% Sb, incl.
    • 1.0m of 10.3% Zn+Pb (0.5% Zn and 9.8% Pb), 601 g/t Ag, 3.19% Cu, 0.19% Sb
  • 9.3m of 17 g/t Ag, 0.17% Cu (from 415m) incl.
    • 2.7m of 35 g/t Ag, 0.36% Cu
  • 11.1m of 12 g/t Ag, 0.42% Cu (from 560m), incl.
    • 2.7m of 26 g/t Ag, 1.10% Cu
• Cu-Ag mineralization associated with steeply south-dipping fault zones, interpreted to be continuation of Cu-Ag bearing fault zones intersected 350m to the NE (in holes 25-3552-40, -44 and -47, announced last year)
• This adds strong evidence supporting hypothesis that Cu-Ag bearing fault zones may extend along the strike length of the entire Ballywire discovery
• One remaining batch of assays is pending from today’s hole, including from another fault zone

“Today’s results represent a major step forward in our understanding of the Deeper Cu-Ag target at Ballywire,” stated Bart Jaworski, CEO. “With significant Cu-Ag bearing fault structures now pierced along two drill fences located 350m apart, we have much higher conviction that Deeper Cu-Ag mineralization may extend across the entire discovery to date. This may also help us vector towards more mineralization beyond the current discovery footprint. It is also highly encouraging that today’s results immediately below the Waulsortian Limestone add up to our best hit to date – over 50m of strong zinc-lead and silver mineralization with significant copper grades. Overall, today’s intercepts demonstrate that Ballywire’s exploration upside continues to accelerate. With a robust treasury and our most ambitious drill campaign to date – four rigs turning at Ballywire – we are poised to continue unlocking this discovery’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 75 holes drilled and reported by Group Eleven to date, including the most recent two holes (25-468-18, 25-3552-50) reported today. Today’s results from 25-3552-51 are in addition to partial assays announced on 19-Jan-2026. A third and final batch of results from this hole is pending and expected to be released over the coming weeks. Today’s results are summarized above and below (see Exhibits 1 to 6).

Mineralization reported today consists predominantly of sphalerite, galena and pyrite, with Cu-Ag bearing zones also containing chalcopyrite and suspected tennantite-tetrahedrite. Germanium (and gallium) assays were run for a key portion of the intercept announced 19-Jan-2026 from hole 25-3552-51. The results totalled 28.9m of 7.3 g/t Ge and 5.5 g/t Ga (plus 15.6% Zn+Pb, 570 g/t Ag, 0.69% Cu, 0.06% Sb), including (a) 3.8m (from 339.8m) of 16.0 g/t Ge, 5.6 g/t Ga (plus 27.9% Zn+Pb, 82 g/t Ag); (b) 6.6m (from 350.0m) of 4.8 g/t Ge and 8.9 g/t Ga (plus 15.9% Zn+Pb, 83 g/t Ag); and (c) 7.8m (from 360.3m) of 9.9 g/t Ge and 6.2 g/t Ga (plus 20.5% Zn+Pb, 1586 g/t Ag, 1.89% Cu and 0.17% Sb).

Note: Of the four gravity-high anomalies above, only the ‘C’ anomaly has been systematically drilled to date; “Anom. Minz” means anomalous mineralization (see text for details)

Hole 25-468-18 was drilled on the SW portion of the Ballywire discovery, filling in an approximate 100m long gap (see Exhibit 2) between holes 25-468-17 (see news release dated 19-Jan-2026) and G11-468-01 (see news release dated 07-Sep-2021). The hole returned 14.2m of 0.31% Zn+Pb (0.17% Zn and 0.14% Pb) and 2.2 g/t Ag (from 301m downhole), including 0.9m of 1.43% Zn+Pb (1.14% Zn and 0.29% Pb) and 5.7 g/t Ag. This demonstrates continuity of the mineralizing system at this locality, justifying follow-up drilling further up-dip (planned later this year) and down dip (ongoing) along this section.

Hole 25-3552-50 was drilled approx. 400m ESE of its nearest drill hole (25-3552-49), on the far east portion of the Ballywire discovery (see Exhibit 2 and 6), approx. halfway towards gravity anomaly D (currently being drill tested). This hole returned anomalous mineralization totalling 2.9m of 0.04% Zn+Pb (0.04% Zn and 0.01% Pb) (from 406m downhole), adding confidence in vectoring towards anomaly D.

Four rigs are currently drilling at Ballywire, with the aim of completing over 20,000m in Ireland in 2026 (approx. 85% of which is planned at Ballywire). Currently, ten (10) new holes are completed (and in the process of being logged, sampled and assayed), in progress and/or about to be drilled. These are shown in Exhibit 2, including: (i) three holes collared on the fence hosting today’s 25-468-18 results; (ii) one hole testing down-dip of today’s 25-3552-51 results; (iii) one hole testing approx. 100m SW of today’s 25-3552-51; (iv) three holes planned in a fan pattern immediately SW of G11-3552-08; (v) one hole drilling immediately up-dip of today’s hole 25-3552-50; and (vi) one hole testing 300m NE of the above drilling, testing the ‘D’ gravity-high anomaly (see Exhibit 2 and 6).

Notes to Exhibit 7: (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
