Group Eleven Announces Uplisting to OTCQB Market

Group Eleven Resources Corp. (TSXV: ZNG) (OTCQB: GRLVF) (FSE: 3GE) ("Group Eleven" or the "Company") is pleased to announce the latest step-out drill results from the Zn-Pb-Ag horizon at its Ballywire discovery ("Ballywire") at the 100%-owned PG West Project ("PG West"), Republic of Ireland. Drilling at Ballywire's deeper, Cu-Ag target is in progress (to be reported in due course).

Highlights:

•  25-3552-35 (a 50m step-out to the NE from previous drilling, along the Zn-Pb-Ag horizon) intersected:
  • 53.9m of 7.9% Zn+Pb (4.7% Zn and 3.2% Pb), 99 g/t Ag and 0.20% Cu, including
   
  •  39.7m of 9.5% Zn+Pb (5.6% Zn and 3.9% Pb), 131 g/t Ag and 0.27% Cu, including
   
  • 18.3m of 16.1% Zn+Pb (8.9% Zn and 7.2% Pb), 233 g/t Ag and 0.42% Cu, including
   
  • 5.6m of 16.6% Zn+Pb (8.0% Zn and 8.5% Pb), 370 g/t Ag and 0.86% Cu
   
  • True thickness is estimated to be 90-100% of the intervals noted above and below
   
 
• Three Cu-Ag enriched zones were also intersected below the above intercept in the same hole:
  • 5.5m of 3.2% Zn+Pb (0.9% Zn and 2.2% Pb), 209 g/t Ag and 0.49% Cu, including
    • 0.9m of 2.1% Zn+Pb (1.5% Zn and 0.6% Pb), 831 g/t Ag and 2.46% Cu and
   
  • 0.9m of 195 g/t Ag and 0.21% Cu and
   
  • 3.5m of 7.1% Zn+Pb (3.5% Zn and 3.6% Pb), 134 g/t Ag and 0.34% Cu, including
    • 0.9m of 3.5% Zn+Pb (0.5% Zn and 3.0% Pb), 224 g/t Ag and 0.63% Cu 
   
 
• These results extend the strike length of the immediate Ballywire discovery corridor from 1,250m to 1,300m, while demonstrating much thicker mineralization than previously encountered
 
• This corridor is hosted within a larger 2.6km long trend of robust mineralization pierced by drilling at Ballywire to date, along a prospective trend of over 6km (defined by four regional gravity-high anomalies, only one of which has been systematically drill tested to date)
 
• Today's elevated Cu-Ag values further substantiate the Company's 'deeper Cu-Ag' target (100-200m below the Zn-Pb-Ag horizon), currently being drill tested (second hole in progress)
 
• Three rigs are turning at Ballywire with over 4,000m of drilling completed year-to-date; Group Eleven aims to complete 8,000-10,000m in 2025 (fully funded)
 

"Today's hole represents our thickest intercept yet at the Ballywire discovery, surpassing our 29.6 metres of 10.6% Zn+Pb, 78 g/t Ag and 0.15% Cu announced in June 2024," stated Bart Jaworski, CEO. "Not only does this intercept extend strike and show exceptional mineralized thickness but also demonstrates zones of strong copper-silver values. This adds to growing evidence suggesting a deeper Cu-Ag horizon one to two hundred metres below the main Ballywire discovery horizon. This deeper target is currently being drilled, with one hole finished and a second started. We look forward to releasing these results as soon as assays are available. With three rigs turning each on excellent targets at Ballywire and a recently announced strengthened cash position of C$4.3 million, Group Eleven is poised to keep generating shareholder value through the drill bit for the foreseeable future."

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 53 holes drilled and reported by Group Eleven to date, including the most recent hole (25-3552-35) reported today (see Exhibits 1 to 3).

Drilling at Ballywire continues with three rigs. Currently, eight (8) new holes are completed (and in the process of being logged, sampled and assayed). Six of these holes are shown in Exhibit 1, with two other holes near gravity-high anomaly 'D' (located 1.3km to the ENE). Recently strengthened financial position provides Group Eleven flexibility to either ramp-up drilling in 2025 and/or extend its runway for drilling well into 2026.

Assays from 25-3552-35 are summarized below (see Exhibit 3). Strong mineralization starts to occur within the Waulsortian Limestone at 120.6m downhole and continues intermittently until 187.9m, at which point, mineralization becomes more consistent through to near the base of the Waulsortian Limestone at 242.9m. Below the Waulsortian Limestone, several horizons of elevated copper-silver occur. Mineralization consists predominantly of sphalerite, galena and pyrite, with the copper-silver bearing zones also containing chalcopyrite and suspected tennantite-tetrahedrite.

Group Eleven Resources Corp. (TSXV: ZNG) (OTCQB: GRLVF) (FSE: 3GE) ("Group Eleven" or the "Company") is pleased to announce funding from early warrant and option exercise and provide an update on the Company's Carrickittle West prospect, spanning 77.64%-owned Stonepark Project ("Stonepark") and 100%-owned PG West Project ("PG West"), Republic of Ireland. Drilling continues with three rigs at the Ballywire discovery ("Ballywire") at PG West.

Highlights:

• Early warrant and option exercises totalling proceeds of $2,206,752 received since C$2.5 mln placement closed Feb-28-2025 (including $1,852,902 since publication of Q1 2025 financials)
• Extra proceeds provide flexibility to ramp-up 2025 drilling and/or extend drilling well into 2026
• At Carrickittle West, four holes were completed late 2024 and early 2025 (three holes located at Stonepark and one hole located at PG West)
• Most significant target to emerge from this drilling is the Kilteely Prospect (large breccia body spanning at least 1.5km in strike)
  • G11-2840-30 (365m step-out) intersected numerous zones of weak breccia with pyrite over narrow intervals throughout the Waulsortian Limestone; some breccias returned anomalous Zn-Pb and Cu levels, with the base of the Waulsortian Limestone (key target horizon) hosting minor disseminated pyrite and trace sphalerite
  • Several occurrences of trace sphalerite are present in the hole, potentially suggesting increasing proximity to stronger mineralization relative to previous drilling at Kilteely
• Three other target areas have also emerged at Carrickittle West, including the Bruff Prospect
  • G11-449-03 (315m step-out), targeting part of the >50km long Coonagh Castle Fault, intersected extensively dolomitized Waulsortian Limestone and a very prominent zone of calcite extending over 35m (from 294m), similar to Ballywire
  • Base of Waulsortian is highly dolomitized over a 25m interval with similarities to 'fault dolomite' observed at Ballywire, which indicates intense hydrothermal fluid flow and close proximity to a major fault; follow-up drilling is highly warranted

"Carrickittle West continues to be one the best drill targets in Ireland," stated Bart Jaworski, CEO. "Being within only a few kilometres of 45 and 5 million tonnes of mineralization from Glencore's Pallas Green¹ and our Stonepark² deposits, respectively, this prospect has a real chance at hosting the southern half 'mirror-image' of the mineralizing system operating at the northern side of the Limerick Volcanic Complex. Today's drill results demonstrate the presence of key attributes – brecciation, faulting, hydrothermal fluids and significant pyrite. The fact we're also starting to pick up sphalerite locally in some of the drilling suggests we may be getting close to the high-grade. We look forward to follow-up drilling. Meanwhile, three rigs are turning at our Ballywire discovery and we anticipate the next drill results over the coming few weeks."

Ballywire Drill Update

Drilling at Ballywire continues with three rigs. Currently, nine (9) new holes are completed (and in the process of being logged, sampled and assayed). Seven of these holes are shown in Exhibit 1, with two other holes near gravity-high anomaly 'D' (located 1.3km to the ENE). Additional funding described above, nearly equal to Group Eleven's most recent private placement, increases the Company's cash to approx. C$4.3 mln (as at 13-Jun-2025). This strengthened financial position provides Group Eleven flexibility to either ramp-up drilling in 2025 and/or extend its runway for drilling well into 2026.

New Step-Out Holes at Carrickittle West Target Area

The Carrickittle West target area spans the Company's 77.64%-owned Stonepark Project and 100%-owned PG West Project. In addition to holes G11-2840-30 and G11-449-03 summarized above (and shown in Exhibits 2-4), the following is a summary of the remaining two holes drilled (see Exhibit 2).

• G11-450-04 (570m step-out from previous drilling in area)
  • Planned to test the hanging wall (north side) of the Kilteely Fault but intersected the footwall (south side) instead
  • The base of the Waulsortian Limestone comprises a fine-grained dolomite, similar to Ballywire, with a series of breccias similar to black matrix breccia ("BMB", host alteration to Zn-Pb mineralization at Lisheen, Galmoy, Silvermines and Pallas Green)
  • Pyrite is extensive in breccias with anomalous levels of base metals
  • Colloform semi-massive pyrite is present from 265.27m to 265.73m and at 267.5m
  • Future drilling will target base of Waulsortian on the hanging wall of the Kilteely Fault
• G11-2531-02 (710m step-out from previous drilling in area)
  • Planned to test the hanging wall of Coonagh Castle Fault, but intersected the footwall instead
  • Waulsortian is dolomitized throughout and contains extensive zones of pyritic brecciation at the top and base of the Waulsortian Limestone
  • Breccias have vague similarity to Stonepark-style BMB

A follow up drill program is being designed, with one hole planned at Stonepark later this year and the remainder of holes to be drilled in 2026.

Group Eleven Resources Corp. (TSXV: ZNG) (OTC Pink: GRLVF) (FSE: 3GE) ("Group Eleven" or the "Company") is pleased to invite investors and other interested parties to attend the Company's upcoming interview with Radius Research.

CEO Bart Jaworski is providing an update on ZNG's Ballywire high-grade zinc-lead-silver (+/- germanium, +/- copper) discovery in the Republic of Ireland.

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 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:

•  25-3552-31, a 65m step-out hole, intersected two strongly mineralized horizons:
  •  Cu-Ag horizon (starting at 348.7m downhole)
    • 19.9m of 1.46% Cu and 356 g/t Ag, including
     
    • 12.0m of 2.30% Cu and 560 g/t Ag, including
     
    • 6.4m of 3.72% Cu and 838 g/t Ag
     
   
  •  Zn-Pb-Ag horizon (starting at 297.0m downhole)
    • 47.1m of 4.5% Zn+Pb (3.1% Zn and 1.4% Pb) and 22 g/t Ag, including
     
    • 25.9m of 7.4% Zn+Pb (5.1% Zn and 2.3% Pb) and 35 g/t Ag, including
     
    •  12.9m of 11.0% Zn+Pb (7.7% Zn and 3.2% Pb) and 57 g/t Ag, including
     
    • 3.7m of 20.4% Zn+Pb (15.8% Zn and 4.6% Pb) and 151 g/t Ag
     
   
 
• Up to 10.45% Cu (over 0.80m) and up to 1,880 g/t Ag (over 0.86m) intersected in the Cu-Ag horizon; to the Company's knowledge, this represents the highest-grade Ag intercept in Ireland over the last >60 years (by any operator) and similarly, one of the highest-grade Cu intercepts
 
• Cu-Ag horizon consists of replacement-style mineralization along the base of the Waulsortian Limestone in proximity to a fault structure; mineralization appears to consist mostly of tennantite-tetrahedrite (detailed mineralogy work to be undertaken in due course)
 
• Noteworthy is the presence of elevated antimony in the Cu-Ag zone, grading 0.27% Sb within the above 6.4m interval (including 0.80m of 10.45% Cu, 1215 g/t Ag and 0.83% Sb)
 
• This hole expands the footprint of the 2.6km long discovery trend by at least 65m down-dip, to a total of at least 170m down-dip along this section (and remains open further down-dip)
 
• Drilling continues at Ballywire with two rigs testing (i) the NE extension and (ii) 1.3km ENE of the Ballywire discovery in the vicinity of the prospective 'D' gravity-high anomaly; a third rig was added this week, testing the deeper Cu-Ag target (below the Waulsortian Limestone)
 

"Intersecting spectacular copper-silver grades over significant thicknesses is a pivotal moment for the Ballywire discovery," stated Bart Jaworski, CEO. "These results not only strongly point to a stratigraphically deeper Cu-Ag horizon but also represent a proof of concept that substantial grades and thicknesses of copper and silver exist at the discovery, in addition to excellent grades of Zn-Pb. The growing presence of critical minerals at Ballywire, namely, copper, germanium and now potentially antimony, highlights the rising strategic importance of this discovery for Ireland, the EU and our shareholders. With today's Cu-Ag milestone, continued drilling to the NE and along our prospective 6km trend, plus the start of drilling with our third rig, we are poised to further grow shareholder value as the year progresses."

New Step-Out Holes at Ballywire Discovery

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 52 holes drilled and reported by Group Eleven to date, including the most recent four holes (25-3552-30, -31, -32, and -33) reported today (see Exhibits 1 to 7).

High-grade Zn-Pb mineralization from 25-3552-31 (see Page 1 and Exhibits 1 to 4) consists predominantly of sphalerite, galena and pyrite. High-grade Cu-Ag mineralization in this hole consists of suspected tennantite/tetrahedrite, chalcopyrite, sphalerite, galena and pyrite along and/or close to the base of the Waulsortian Limestone (see Exhibit 1). Noteworthy is the presence of elevated antimony within the Cu-Ag zone. For example, the 6.39m interval below, grading 3.72% Cu and 838 g/t Ag, also grades 0.27% Sb (including 0.80m of 10.45% Cu, 1215 g/t Ag and 0.83% Sb).

Exhibit 3. Summary of Assays from 25-3552-31 at Ballywire

Note: True width of the mineralized interval in hole 25-3552-31, as a percentage of the down-hole interval, is estimated to be 50-70%; for photographs of Cu-Ag rich core, see Appendix and www.groupelevenresources.com.

Three other holes released today were drilled in a 150m gap to the NE of 25-3552-31 (25-3552-30, -32 and -33; see Exhibit 2). Hole 25-3552-30 returned nil mineralization, 25-3552-32 returned three intervals of mineralization up to 0.94m of 2.4% Zn+Pb (0.9% Zn and 1.5% Pb) and 8 g/t Ag, and 25-3552-33 returned three intervals of mineralization up to 0.82m of 2.9% Zn+Pb (1.1% Zn and 1.8% Pb) and 7 g/t Ag. These zones of mineralization are narrower and weaker than those at the main discovery trend but generally in line with recent holes drilled further to the ENE (see holes G11-3552-24, -26 and 28 in news release dated 25-Mar-2025). Disseminated copper mineralization, as well as, mineralized veins and fractures, is strengthening towards the north, suggesting massive sulphide mineralization may be present further north (see northern-most purple line in Exhibit 4). A second mineralized trend is also emerging to the south where the interpreted Cu-Ag rich 'feeder' fault pierced by drilling along the main discovery trend appears to correlate with mineralization approx. 350m along strike to the ENE, intersected in G11-3552-08 (see solid and dashed purple lines in Exhibit 4). Drilling is ongoing in the NE area to test the above targets.

Copper-Silver Target

Today's results add to a growing body of evidence that support the interpretation of a Cu-Ag 'feeder' fault parallel to and spatially associated with the main Zn-Pb-Ag discovery at Ballywire (see Exhibit 4). With up to 10.45% Cu and 1,880 g/t Ag in a mineralized horizon near a steeply dipping structure, mineralizing fluids are interpreted to have emanated from deeper in the sedimentary sequence (see Exhibit 5). Meanwhile, the stratigraphy of the region suggests that the Lower Limestone Shale horizon exists approximately 100-200m below the discovery horizon (base of the Waulsortian Limestone). This horizon 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, the mineralizing system has the potential to be much larger than its neighbouring occurrences (based on a relatively larger footprint to date); additionally, any Cu-Ag mineralization would notionally be intact below the existing Zn-Pb-Ag mineralization.

Given the compelling nature of this exploration model, Group Eleven added a third rig and began drilling this deeper Cu-Ag target this week.
