• G11-3552-16 (a 100m step-out to the NE): 24.7m of 3.7% Zn+Pb (2.9% Zn and 0.7% Pb) and 12 g/t Ag (starting from 254m), including:

• Two-rig drill program at Ballywire continues on schedule with the next assay results expected over the coming few weeks (three holes are currently completed with assays pending)

"We are excited that the high-grade footprint of the Ballywire discovery has leapt forward again," stated Bart Jaworski, CEO. "Today's drill results extend known high-grade mineralization at Ballywire by 360m along strike from 890m to 1,250m, and provide compelling evidence that mineralization is intensifying towards the shallower, northeastern portion of the discovery area. The 108.5m intercept announced today is particularly notable given high-grade zones occur throughout the interval."

"Together with historic hole 97-468-2 and our larger step-outs earlier this year, robust mineralization pierced by drilling at Ballywire extends over 2.6km, along a prospective trend of over 6km. Given today's additional intervals of significant massive sulphide, Ballywire is again showing signs of a major zinc-lead-silver discovery. With two rigs turning, we look forward to providing further drill results over the coming few weeks."

Exhibit 5. Summary of Assays from G11-3552-17 at Ballywire

Note: True width of the overall mineralized package above is estimated at approx. 80-100% of the intersected interval; mineralized intercepts from approx. 143m to 200m consist predominantly of a series of steep north-dipping veins, whereas mineralization from approx. 200m to 250m is dominated by flat-lying layers of sphalerite-dominate massive sulphide

Exhibit 6. Summary of Assays from G11-3552-14, -15 and -16 at Ballywire

Note: True width (as a % of the intersected interval) of the overall mineralized package is approx. 90-100% for G11-3552-14, 80-100% for G11-3552-15, 90-100% for G11-3552-16 and 90-100% for G11-2654-03

Most Recent Five 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 31 holes drilled and reported by Group Eleven to date, the most recent five (5) step-out holes (G11-3552-14, -15, -16, -17, and G11-2654-03) of the 2024 program are reported today (see Exhibits 1 to 6).

High-grade mineralization from the above drill holes 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 1).

In addition to the above, G11-2654-03 (testing the 'B' gravity anomaly) extended known mineralization approximately 370m to the southwest from the southwestern edge of the discovery area (see Exhibit 2). The hole returned anomalous mineralization along or near the base of the Waulsortian Limestone. This information coupled with a growing set of structural (fault location) data (see Exhibit 2), suggest mineralization may be faulted southwards in this portion of the Ballywire prospect. Further drilling to the south is warranted and planned for future campaigns.

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.
