Group Eleven Cuts Deeper Cu-Ag Mineralization in 710m Step-Out; Drills 3.7m of 7.7% Zn+Pb, 418 g/t Ag and 1.02% Cu in a Wider 17.6m Interval; Returns Mineralization in First Hole at 'Anomaly A'
Rhea-AI Summary
Group Eleven Resources (OTCQB: GRLVF) reported new assay results from four holes at its 100%-owned Ballywire Zn-Pb-Ag-Cu discovery at the PG West Project in Ireland. Hole 26-3552-56 at the NE end intersected 17.6m grading 4.1% Zn+Pb, 111 g/t Ag and 0.27% Cu, including 3.7m of 7.7% Zn+Pb, 418 g/t Ag and 1.02% Cu within Waulsortian Limestone.
Deeper Cu-Ag mineralization was expanded by step-outs: hole 26-468-24, 710m from the nearest similar test, cut 3.6m of 345 g/t Ag and 0.75% Cu, including 0.6m of 2,120 g/t Ag and 4.50% Cu. Hole 26-3552-60 returned intervals up to 0.19m of 1,355 g/t Ag and 11.00% Cu and a broader 15.4m of 39 g/t Ag and 0.82% Cu. First drilling at gravity-high ‘Anomaly A’ (26-468-25), 2km SW, encountered multiple intervals with base- and precious-metal minerals, indicating a mineralizing system further SW. Four rigs are active, with 13 additional holes in progress and a March $12m financing supporting an increase in funded drilling to approximately 67,000–75,000m.
Positive
- High-grade Waulsortian intercept: 17.6m of 4.1% Zn+Pb, 111 g/t Ag and 0.27% Cu in 26-3552-56, including 3.7m of 7.7% Zn+Pb and 418 g/t Ag.
- Deeper Cu-Ag system extended: 26-468-24 hit 3.6m of 345 g/t Ag and 0.75% Cu, including 0.6m of 2,120 g/t Ag and 4.50% Cu, 710m from prior similar drilling.
- Very high-grade Cu-Ag-Sb intervals: 26-3552-60 intersected 0.19m of 1,355 g/t Ag, 11.00% Cu and 1.30% Sb and 0.74m of 643 g/t Ag and 13.95% Cu within broader mineralized zones.
- New mineralized area at Anomaly A: first hole 26-468-25, 2km SW, shows multiple intervals with malachite, chalcopyrite, tennantite-tetrahedrite, sphalerite and galena, suggesting a mineralizing system further along trend.
- Strongly funded drill program: According to Group Eleven, a $12m March financing supports an increase in funded drilling from 20,000m to approximately 67,000–75,000m at Ballywire.
Negative
- None.

"Today's results represent significant progress on several fronts at Ballywire," stated Bart Jaworski, CEO. "First, we have demonstrated high-grades of Cu-Ag-Sb along the SW end of the currently defined discovery area, 710m away from the nearest such test. Second, a wide zone of Cu-Ag (with Zn+Pb) mineralization was intercepted at the NE end of the discovery area, relatively shallow and within the Waulsortian Limestone. Third, significant Deeper Cu-Ag mineralization was drilled in an 80m step-out returning up to 1355 g/t Ag,

Ballywire Drill Update
The Ballywire prospect at the Company's
Mineralization reported today consists predominantly of sphalerite, galena and pyrite, with Cu-Ag bearing zones containing malachite, chalcopyrite and suspected tennantite-tetrahedrite. Today's results represent some of the strongest Cu-Ag intervals achieved at Ballywire to date. In addition to the above description, note that 26-468-25 at 'Anomaly A' returned strongly anomalous assay values (see Exhibit 7 and 8), including 1.0m of 15 g/t Ag and
Potential for a parallel trend (as illustrated by red question marks in Exhibit 2), began to emerge earlier this year with several recently announced holes (including 25-468-19 and 26-468-23), as further exemplified by today's results from 26-468-24. This hole also adds further evidence that Deeper Cu-Ag mineralization may extend across the entire Ballywire Zn-Pb-Ag discovery, currently known to span 3.2km along a prospective trend of 6km.
Four rigs continue to be actively drilling at Ballywire. Currently, thirteen (13) new holes are completed (and in the process of being logged, sampled and assayed) or in the process of being drilled. These are shown in Exhibits 2 to 4. The Company has a robust treasury bolstered by a

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. Mineralization and resource estimates relating to nearby properties are not necessarily indicative of the mineralization on the Company's assets.
