Group Eleven Extends Strike at Ballywire to 2.6km and Intersects High-Grade Silver and Copper, Including 4.4m of 304 g/t Ag and 0.73% Cu

VANCOUVER, April 4, 2024 - Group Eleven Resources Corp. (TSXV: ZNG) (OTCBB: GRLVF) (FRA: 3GE) ("Group Eleven" or the "Company") is pleased to announce results from the first four holes of the 2024 drill program at the Company's 100%-owned Ballywire zinc-lead-silver discovery ("Ballywire"), PG West Project ("PG West"), Republic of Ireland.

Highlights

• Mineralization intersected in all four step-out holes testing the previously undrilled C2 and C3 gravity-high anomalies (located 530m and 930m east of the Ballywire discovery area)
• Key intersections include:
  • 4.6m of 5.2% Zn+Pb (4.4% Zn and 0.9% Pb) and 15 g/t Ag (from 288.9m down hole), including 1.9m of 6.9% Zn+Pb (5.5% Zn and 1.4% Pb) and 22 g/t Ag within a 59.7m package of intermittent mineralization (not yet fully assayed) in G11-3552-08, a 930m step-out (testing Anomaly C3)
  • 2.7m of 4.3% Zn+Pb (1.1% Zn and 3.2% Pb) and 7 g/t Ag, including 0.6m of 12.9% Zn+Pb (1.5% Zn and 11.4% Pb) and 16 g/t Ag (from 291.5m down hole) within a 22.5m wide zone of mineralization in G11-3552-06, approx. 100m south of the above hole; and
  • 4.4m of 304 g/t Ag, 0.73% Cu and 1.0% Zn+Pb (0.9% Zn and 0.1% Pb) (starting at 331.6m down hole), including 0.6m of 1,440 g/t Ag, 3.03% Cu and 1.6% Zn+Pb (1.5% Zn and 0.2% Pb), the highest silver value ever intersected by the Company, within a 91.9m package of intermittent mineralization in G11-3552-07, a 530m step-out (Anomaly C2)
• The above results combined with the projection of the high-grade trend at the discovery area, suggest that the strength of the system is increasing to the north of the C2 and C3 anomalies
• Drilling continues with two rigs, testing further north on Anomaly C3 and in between the discovery area and Anomaly C2, respectively

"We are very pleased that robust mineralization at Ballywire has now been intersected over a strike length of over 2.6km, up from 1.7km previously," stated Bart Jaworski, CEO. "This extended breadth includes 710m at the discovery area, a historic intercept 1km to the west and now step-out drilling up to 930m to the east. The fact that gravity-high anomalies C2 and C3 are spatially associated with mineralization bodes well for the rest of our prospective trend which is defined by gravity-high anomalies over a strike-length of 6km. We look forward to systematically drill testing these anomalies over the coming weeks and months. With a 2.6km-long footprint, a 6km-long prospective trend and some of the highest silver values ever attained in Ireland, Ballywire is increasingly showing signs of a major zinc-lead-silver discovery."

First Four Holes from 2024 Drill Campaign at Ballywire Discovery

The Ballywire prospect at the Company's 100%-owned PG West Project in Republic of Ireland, is a new zinc-lead-silver discovery (first announced Sept-2022). In addition to 21 holes drilled and reported by Group Eleven to date, the next four step-out holes (G11-3552-05 to -08) of the 2024 program are reported today (see Exhibits 1 to 6). Holes G11-3552-09 to -11 are in-progress.

Mineralization occurs as sphalerite, galena, pyrite, chalcopyrite and suspected tennantite- tetrahedrite, and is bedding parallel along and close to the base of the Waulsortian limestone. Notably, significant volumes of dark grey, dolomitic breccias are present in hole G11-3552-08 (see Exhibit 4). Today's drill results combined with the projection of the high-grade trend at the discovery area (see Exhibits 1 and 2), suggest that the strength of the mineralizing system is increasing to the north of the C2 and C3 gravity-high anomalies.

Notes to Exhibit 8: (a) Pallas Green MRE is owned by Glencore (see Glencore's Resources and Reserves Report dated December 31, 2023); (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.

Planning is underway for a drilling program at the Company's 76.56%-owned Stonepark Project later in 2024. This will include follow-up on drilling at the Carrickittle West target in 2022, which resulted in the first intersection by Group Eleven of a major fault in the Limerick basin. The Company expects to drill a series of widely spaced holes to examine mineralization, brecciation and Waulsortian thickness variations in the area to improve understanding of the best area of potential for a major discovery. This incremental follow-up on the target reduces the risk associated with a single, deep hole and follows the exploration model that successfully resulted in the Ballywire discovery in 2022. In addition, other prospective targets across the Stonepark Project will be drill tested during the course of the program. Further details on the program will be provided in due course.

Technical information in this news release has been approved by Professor Garth Earls, Eur Geol, P.Geo, FSEG, geological consultant at IGS (International Geoscience Services) Limited, and independent 'Qualified Person' as defined under Canadian National Instrument 43-101.

The 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.
