Vancouver, British Columbia--(Newsfile Corp. - January 19, 2026) - Group Eleven Resources Corp. (TSXV: ZNG) (OTCQB: GRLVF) (FSE: 3GE) ("Group Eleven" or the "Company") is pleased to announce the latest nine drill holes from its Ballywire discovery ("Ballywire") at the 100%-owned PG West Project ("PG West"), Republic of Ireland.

Highlights:

• 25-3552-51 - 80m step-out SW of massive sulphide zone, within the Ballywire discovery:

  • 29.9m of 15.3% Zn+Pb (9.7% Zn and 5.5% Pb), 552 g/t Ag and 0.67% Cu (from 339m downhole depth); including

  • 3.8m of 27.9% Zn+Pb (23.5% Zn and 4.4% Pb), 82 g/t Ag; and

  • 8.4m of 18.2% Zn+Pb (10.4% Zn and 7.8% Pb), 1776 g/t Ag, 2.21% Cu, 0.18% Sb, incl.

  • 1.3m of 23.0% Zn+Pb (12.4% Zn and 10.6% Pb), 4260 g/t Ag and 4.58% Cu, 0.46% Sb

• 25-468-19 - new significantly mineralized zone in a 400m gap between two previously drilled holes along a drill fence at the SW portion of the Ballywire discovery:

  • 32.3m of 3.0% Zn+Pb (2.4% Zn, 0.5% Pb), 11 g/t Ag (from 446m downhole), including

  • 2.9m of 6.7% Zn+Pb (5.3% Zn, 1.3% Pb), 55 g/t Ag; and

  • 2.8m of 6.0% Zn+Pb (4.0% Zn, 2.0% Pb), 23 g/t Ag; and

  • 2.8m of 7.3% Zn+Pb (6.6% Zn, 0.7% Pb), 7 g/t Ag; and

  • 2.7m of 5.2% Zn+Pb (4.4% Zn, 0.8% Pb), 10 g/t Ag

"Today's results represent our best hole to date since inception of the Company back in 2015," stated Bart Jaworski, CEO. "Hole 25-3552-51 intersected nearly 30m of excellent zinc and lead grades, including over eight metres of spectacular silver numbers, up to 4,260 g/t, coincident with very strong copper and antimony concentrations. The interval is hosted within a bedding-parallel massive sulphide zone interpreted to be close to true width. Importantly, this hole surprised to the upside, showing a previously unexpected 80m extension of the massive sulphide zone towards the SW, opening new expansion potential in this area. Importantly, this hole continues further down to test the Deeper Cu-Ag target below today's interval. That work is ongoing with assays pending."

"Today's other key development is the discovery of a significant new zone at the SW-end of the current discovery. Hole 25-468-19 intersected over 32m of mineralization, hosting four intervals, each nearly three metres thick, grading robust zinc-lead and silver. This new zone is 295m SSE of previously intersected high-grade mineralization, adding evidence of significant mineralization south of, and potentially parallel to, the current discovery trend. Follow-up drilling here is underway."

"Overall, significant expansion of massive sulphide lenses plus new zones of mineralization to the SW, demonstrate that Ballywire's exploration upside continues to ramp up. With a robust treasury and our most ambitious drilling 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 73 holes drilled and reported by Group Eleven to date, including the most recent nine holes (25-468-17, -19, -20, -21; 25-3552-43, -46, -48, -49 and -51) reported today (see Exhibits 1 to 6).

Assays from today's drill holes are summarized above and below. Today's results from 25-3552-51 are partial and limited to only high-grade mineralization within the Waulsortian Limestone, however, samples from above and below today's results, are in progress with assays pending. Mineralization reported today consists predominantly of sphalerite, galena and pyrite, with the Cu-Ag bearing zones also containing chalcopyrite and suspected tennantite-tetrahedrite.

Exhibit 5. Summary of Assays from 25-468-17, -19, -20 and -21 at Ballywire

In addition to the above descriptions, note that 25-468-17, -20 and -21 have successfully intersected mineralization approximately 230m NNE of previously known mineralization (see G11-468-01 in Exhibit 4). This shows that mineralization has now been intercepted over a down-dip distance of greater than 1,050m along this section. Given the large step-out distances between holes, it is possible that high-grade zones of massive sulphide remain to be discovered. Hence, closer spaced drilling along this section is now ongoing.

Almost two kilometres to the NE of the drill holes reported above, a fence of four holes was drilled approximately 200m NE of previous drilling (see Exhibit 2), each intersecting visible mineralization:

• 25-3552-43 - 3.2m of 0.06% Zn+Pb (0.05% Zn and 0.01% Pb) (from 207m downhole), including 1.2m of 0.11% Zn+Pb (0.10% Zn and 0.01% Pb)

• 25-3552-46 - 2.9m of 0.22% Zn+Pb (0.17% Zn and 0.05% Pb) (from 261m downhole), including 1.0m of 0.35% Zn+Pb (0.27% Zn and 0.08% Pb)

• 25-3552-48 - 23.5m of 0.18% (0.08% Zn and 0.10% Pb), 1.4 g/t Ag (from 294m downhole), including 1.8m of 0.39% Zn+Pb (0.03% Zn and 0.36% Pb), 8.7 g/t Ag and 1.8m of 0.65% Zn+Pb (0.61% Zn and 0.04% Pb), 0.7 g/t Ag

• 25-3552-49 - 4.7m of 0.22% Zn+Pb (0.11% Zn and 0.11% Pb), 0.9 g/t Ag (from 365m downhole), including 0.9m of 0.49% Zn+Pb (0.21% Zn and 0.28% Pb) and 1.9 g/t Ag

Drilling at Ballywire re-started in early January after the Christmas break. 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, eleven (11) 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) four holes collared on the fence hosting today's 25-468-19 results; (ii) one hole testing down-dip of today's 25-3552-51 results; (iii) three holes planned in a fan pattern immediately SE of 25-3552-39; (iv) two holes drilling approx. 400m SE of 25-3552-49; and (v) 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, 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.
