Group Eleven Resources Corp. (TSXV: ZNG) (OTC Pink: GRLVF) (FSE: 3GE) ("Group Eleven" or the "Company") is pleased to announce assay results from four new holes (and additional assays from a previously announced hole) from the ongoing drill program at the Company's 100%-owned Ballywire zinc-lead-silver discovery ("Ballywire"), PG West Project ("PG West"), Republic of Ireland.

Highlights:

• G11-3552-29 intersected (from 189.3m):
  • 130.7m of 2.3% Zn+Pb (2.0% Zn and 0.3% Pb) and 13 g/t Ag, including
  • 7.5m of 20.1% Zn+Pb (19.1% Zn and 1.0% Pb) and 51 g/t Ag, including
  • 5.7m of 24.1% Zn+Pb (23.2% Zn and 1.0% Pb) and 60 g/t Ag, including
  • 2.2m of 37.5% Zn+Pb (36.9% Zn and 0.7% Pb) and 72 g/t Ag
  • Represents a 55m step-out down-dip from G11-3552-27
• G11-3552-27¹ intersected (from 201.5m):
  • 70.5m of 3.4% Zn+Pb (2.2% Zn and 1.2% Pb) and 41 g/t Ag, including
  • 25.7m of 7.9% Zn+Pb (5.7% Zn and 2.2% Pb), 78 g/t Ag and 0.12% Cu and
  • 4.2m of 2.0% Zn+Pb (0.4% Zn and 1.6% Pb), 172 g/t Ag and 0.66% Cu, including
  • 0.9m of 3.6% Zn+Pb (0.9% Zn and 2.6% Pb), 511 g/t Ag and 2.01% Cu
  • Located 50m down-dip from G11-3552-25 (announced 06-Feb-2025)
• G11-3552-29 expands the footprint of the recently announced 360m long, flat-lying zone of zinc-rich massive sulphide lenses by at least 50m down-dip, to a total of at least 125m down-dip
• Drilling continues at Ballywire with two rigs testing further down-dip of the two holes released today, plus the NE extension; assay results are expected in due course
• In several weeks, drilling will also begin testing (a) a Cu-Ag target below the Zn-Pb-Ag discovery horizon; and (b) a step-out target 1.3km to the ENE of the Ballywire discovery testing in the vicinity of the prospective 'D' gravity-high anomaly, at a locality with abundant calcite similar to the calcite typically observed immediately above high-grade mineralization along the discovery trend

"We are very pleased to see the NE massive sulphide zone expanded by a ninth consecutive high-grade hole," stated Bart Jaworski, CEO. "Additional excellent Ag and Cu values also continue to point to a stratigraphically deeper Cu-Ag horizon, which we are aiming to start drill testing for the very first time over the next few weeks. We also look forward to stepping out 1.3km ENE towards a very prospective area near the 'D' gravity high anomaly. This locality hosts abundant calcite bodies, commonly seen above high-grade mineralization at Ballywire. A nearby historic hole is also mineralized. With the Cu-Ag target, continued drilling to the NE and larger step outs along our prospective 6km trend, 2025 promises to be an exciting year of exploration for Group Eleven."

New Step-Out Holes at Ballywire Discovery

The Ballywire prospect at the Company's 100%-owned PG West Project in Republic of Ireland, is a relatively new zinc-lead-silver discovery (first announced Sept-2022). In addition to 44 holes drilled and reported by Group Eleven to date, the most recent four holes (G11-3552-24, -26, -28, and -29) and additional assays for previously announced hole, G11-3552-27, are reported today (see Exhibits 1 to 7).

High-grade mineralization from G11-3552-27 and -29 (see Page 1 and Exhibits 1 to 4) 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).

Exhibit 3. Summary of Assays from G11-3552-24, -26, -27, -28 and -29 at Ballywire

Note: True width of the intervals above as a percentage of the intersected interval is 90% (G11-3552-27), 80-90% (G11-3552-29), 90-100% (G11-3552-24), 80-90% (G11-3552-26) and 90-100% (G11-3552-28)

Holes drilled as 300m step-outs to the NE (G11-3552-24, -26 and -28; see Exhibit 2) returned zones of mineralization narrower and weaker than those at the main discovery trend (see Exhibit 3). Disseminated copper mineralization, as well as, mineralized veins and fractures, however, are strengthening towards the north, suggesting massive sulphide mineralization may be present further north (see northern-most projected mineralized trend in Exhibit 4). A second mineralized trend is also emerging to the south where the interpreted Cu-Ag rich 'feeder' fault pierced by drilled along the main discovery trend (see solid purple line in Exhibits 2 and 4) appears to correlate with mineralization intersected in G11-3552-08 (see Exhibit 2). More drilling is ongoing in the NE area to test the above targets.

Key 2025 Exploration Targets at Ballywire Discovery

Copper-Silver Target

As drilling progresses at Ballywire, it is increasingly evident that there exists an interpreted Cu-Ag 'feeder' fault parallel to and spatially associated with the main Zn-Pb-Ag discovery at Ballywire (see Exhibit 2). This 'feeder' fault hosts mineralization with up to 5.90% Cu and 1,440 g/t Ag, interpreted to have been transported by mineralizing fluids from below by vertical to steeply-dipping structures (see Exhibit 5). Today's results provide further evidence, with grades up to 2.01% Cu and 511 g/t Ag (see Exhibit 3). Meanwhile, the stratigraphy of the region suggests that approximately 100-200m below the discovery horizon (base of the Waulsortian Limestone), is the Lower Limestone Shale horizon, which hosts four well known Cu-Ag historic occurrences in the surrounding area (see Denison, Oola, Gortdrum and Tullacondra in Exhibit 8, located approx. 5km, 9km, 10km and 45km away from Ballywire, respectively).

These historic Cu-Ag occurrences can be interpreted as the eroded remnants of originally more vertically extensive mineralizing systems, likely representing the roots of stratigraphically higher Zn-Pb-Ag mineralization. At Ballywire, there is a chance the mineralizing system is much larger than at the neighbouring deposits (based on relatively large footprint to date), and if it is there, any Cu-Ag mineralization would notionally be intact below the existing Zn-Pb-Ag mineralization.

Given the compelling nature of the above exploration model, Group Eleven aims to begin drilling this deeper Cu-Ag target over the coming several weeks.

Calcite Body Vectors

As drilling progresses at Ballywire, it is increasingly evident that high-grade Zn-Pb-Ag mineralization at Ballywire is spatially associated with steeply dipping bodies of calcite (see Exhibit 6), interpreted to represent the 'exhaust' from the mineralization process below (i.e. dissolved limestone at the mineralized horizon is re-precipitated as calcite bodies immediately above). These calcite bodies may prove to be a strong exploration vector along the undrilled remainder of Ballywire's prospective 6km trend.

Two shallow historic holes, located 1.3km ENE from the current boundary of the Ballywire discovery, intercepted such calcite bodies (see Exhibits 4 and 7), yet were never followed up. This locality is also near the prospective 'D' gravity high anomaly and historic hole, 99-3352-05 (see Exhibit 7), which intersected mineralization of a tenor typically seen peripheral to massive sulphide zones at the discovery trend. Group Eleven aim to test this locality in the coming weeks.

Separately, two historic holes approx. 300m and 600m to the WSW, respectively, from the current boundary of the Ballywire discovery, also intercepted abundant calcite zones (see Exhibits 4 and 7) and were never followed up. Group Eleven aims to test these locations in due course.

Looking forward, six (6) drill holes (G11-3552-30 to -35; see Exhibit 2) are in progress with results expected in due course. Exhibit 2 shows drilling to date across 1.25km of the overall 2.6km long trend (see Exhibit 4) of significantly mineralized drill intercepts. This in turn is hosted within a 6km long prospective trend defined by four gravity high anomalies, only one of which (anomaly 'C') is systematically drilled to date (see Exhibit 7).

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.
