Group Eleven Drills Best Hole Yet at Ballywire Discovery: 29.6m of 10.6% Zn+Pb and 78 g/t Ag

VANCOUVER, June 11, 2024 - Group Eleven Resources Corp. (TSXV: ZNG) (OTCBB: GRLVF) (FRA: 3GE) ("Group Eleven" or the "Company") is pleased to announce results from the most recent 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

• Best intersection to date at Ballywire: 29.6m of 10.6% Zn+Pb (4.0% Zn and 6.6% Pb), 78 g/t Ag and 0.15% Cu (from 283.4m down hole), in G11-3552-12, a 180m step-out from the discovery area, including:
  • 12.9m of 16.6% Zn+Pb (5.8% Zn and 10.8% Pb), 123 g/t Ag and 0.19% Cu, including
    • 5.2m of 24.1% Zn+Pb (2.8% Zn and 21.3% Pb), 76 g/t Ag and 0.10% Cu and
    • 6.8m of 12.6% Zn+Pb (8.5% Zn and 4.1% Pb), 172 g/t Ag and 0.29% Cu
  • Mineralization consists predominantly of massive and semi-massive sulphide, as well as disseminated and vein hosted sulphide mineralization
• G11-3552-12 was drilled approximately 50m up-dip of hole G11-3552-09 which returned a 21.8m zone of mineralization, including 2.8m of 4.1% Zn+Pb (3.4% Zn and 0.8% Pb) and 5 g/t Ag, suggesting mineralization was strengthening up-dip and to the north
• Mineralization intersected in all four step-out holes
• Drilling continues with two rigs, testing 50m up-dip and to the north of G11-3552-12 and testing gravity anomaly B, respectively; with further holes planned for follow-up drilling at gravity anomaly C2

"With an intercept of over 29 metres of high-grade mineralization, G11-3552-12 is by far our best hole to date at Ballywire," stated Bart Jaworski, CEO. "We are excited that high-grade mineralization over a strike of 710m at the discovery area has now been extended by 180m, or 25%, to a new total of 890m. We are also pleased to see record widths of high-grade mineralization in this hole potentially indicating that we may be vectoring in towards a higher grade and more robust part of the system. To date, we have intersected robust mineralization at Ballywire over a strike length of 2.6km, from an historic high-grade intercept 1km west of the discovery area, through the 890m strike of the discovery area to the large step-out holes announced in April 2024. Our prospective trend, informed by gravity-high anomalies along the Waulsortian Limestone has a strike-length of over 6km. We look forward to continuing to systematically drill testing these anomalies. With a 2.6km-long footprint, a 6km-long prospective trend and increasingly robust intervals of massive sulphide, Ballywire is increasingly showing signs of a major zinc-lead-silver discovery."

Most Recent 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 25 holes drilled and reported by Group Eleven to date, the most recent four step-out holes (G11-3552-09, to -12) of the 2024 program are reported today (see Exhibits 1 to 6).

Exhibit 3. Summary of Assays from G11-3552-12 at Ballywire

High-grade mineralization in G11-3552-12 consists predominantly of massive and semi-massive sulphide (sphalerite, galena, pyrite, chalcopyrite and suspected tennantite-tetrahedrite), as well as, disseminated and vein hosted sulphide mineralization. Mineralization occurs along and/or close to the base of the Waulsortian limestone (see Exhibit 4).

Today's drill results extend known high-grade massive sulphide mineralization by 180m or 25%, from a strike length 710m to 890m (see Exhibits 1 and 2). G11-3552-12 represents the strongest mineralization to date at Ballywire, adding to an already strong set of previous intercepts (e.g. 11.2m of 8.9% Zn+Pb and 83 g/t Ag in G11-3552-03; and 10.8m of 10.0% Zn+Pb and 109 g/t Ag in G11-468-03, etc, (see Exhibit 1).

The extensive envelope of massive and semi-massive sulphide mineralization in G11-3552-12 justifies further drilling eastwards, especially towards hole G11-3552-07 (360m away) which intersected very high grades of silver and copper (see Group Eleven's news release dated 04-Apr-2024) suggesting proximity to a feeder structure.

Elevated germanium levels are correlated with high zinc concentrations in previous holes at Ballywire. Germanium will be assayed in G11-3552-12 in due course.

G11-3552-10 and -11, located 50m and 100m north of G11-3552-08, respectively, returned weak mineralization (see Exhibit 5) along or near the base of the Waulsortian Limestone.

Notes to Exhibit 7: (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.
