Group Eleven Drills Best Hole Yet At Ballywire: 39.7M Of 9.5% Zn+Pb, 131 G/T Ag And 0.27% Cu, Incl. 5.6M Of 16.6% Zn+Pb, 370 G/T Ag And 0.86% Cu

(MENAFN- Newsfile Corp) Vancouver, British Columbia--(Newsfile Corp. - July 2, 2025) - 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.
