Group Eleven Drills 130.1m of 0.50% Cu and 20.8 g/t Ag, Including New Zone of 13.2m of 0.37% Cu and 16.3 g/t Ag at Tullacondra Cu-Ag Prospect, Near PG West Project, Ireland
Vancouver, Canada, May 5th, 2022 - Group Eleven Resources Corp. (TSX-V: ZNG; OTC: GRLVF; FRA: 3GE) (“Group Eleven” or the “Company”) is pleased to report assay results from the Company’s maiden drill hole recently completed at the Tullacondra copper-silver historic estimate1 (“Tullacondra”), 20km south of the Company’s PG West project (“PG West”), Ireland. Separately, follow-up drilling at the Company’s Ballywire zinc prospect, PG West, Ireland, has now begun.
Highlights:
- G11-3535-01 intersected 130.1m of 0.50% Cu and 20.8 g/t Ag (from 5.0m downhole depth; true width 60-90%), including 65.1m of 0.64% Cu and 29.5 g/t Ag, representing the best hole drilled to date at the prospect (versus 106.4m of 0.56% Cu and 24.2 g/t Ag, historically)
- A silver-rich portion of the interval measured 3.95m of 143.7 g/t Ag and 1.24% Cu (from 97.6m; true width 80%), including 0.20m of 639.0 g/t Ag and 4.54% Cu, representing the highest silver grade attained to date at the prospect (versus 426.1 g/t Ag, historically)
- A newly-identified zone of 13.2m grading 0.37% Cu and 16.3 g/t Ag (true width 80%) was intersected from 121.9m downhole, including a silver and copper-rich horizon of 0.40m of 303.0 g/t Ag and 5.37% Cu (highest copper grade to date at the prospect, versus 1.78% Cu, historically)
- Mineralization in G11-3535-01: (a) is significantly wider than in the two closest historic holes collared 50m to the north and south (64.1m of 0.71% Cu and 25.6 g/t Ag; and 10.1m of 0.38% Cu and 10.1 g/t Ag, respectively); and (b) confirms the continuity of robust Cu-Ag mineralization intersected in historic holes drilled over 50m to the east and west, respectively
- Overall, the historic estimate1 at Tullacondra remains open in most directions and potential exists to find look-alike bodies elsewhere on the property (e.g. two historic holes drilled 470m apart and over 300m to the south interested 42.7m of 0.14% Cu and 9.2m of 0.17% Cu, respectively)
- Zinc potential also exists at Tullacondra within the Waulsortian Limestone which is preserved on the property and underlain by stratigraphically-lower, copper-bearing horizons
- Follow-up drilling at Tullacondra is strongly warranted and the Company aims to provide an update over the near-medium term on the potential next phase of exploration at the project
“We are excited to see such robust numbers coming from Tullacondra, especially with grades over 5% copper and 600 g/t silver,” stated Bart Jaworski, CEO. “It is significant that a previously unknown zone of mineralization, now representing the strongest zone of copper on the property, has been discovered within the Old Red Sandstone – a lithological unit not typically the focus of much attention in Ireland. Tullacondra is trucking distance from our key zinc and copper-silver prospects at the nearby PG West and Stonepark Projects and we look forward to unlocking further shareholder value as our ongoing 2022 drill program (over 6,000m and two rigs) progresses and now transitions to include Ballywire.”
Location of Tullacondra Prospect near PG West Project (100% interest), Ireland
The Tullacondra Cu-Ag prospect is located approx. 20km south of the Company’s PG West Project (100%-interest), located in SW Ireland (see Exhibit 1). The prospect is also located approx. 45km from the Company’s Stonepark zinc deposit2 and Glencore’s Pallas Green zinc deposit3, as well as, 40-50km from the Company’s Denison and Gortdrum Cu-Ag prospects.

Notes to Exhibit 1: (a) Pallas Green MRE is owned by Glencore (see Glencore’s Resources and Reserves Report dated Dec 31, 2021); (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, which consists of two adjacent and distinct historic estimates of (i) 3.6 million tonnes of 0.7% copper and 28 g/t silver (“copper-rich zone”) and (ii) 0.6 million tonnes of 150 g/t silver and 0.6% copper (“silver-rich zone”) 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 1985; 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.

Recent Drilling at Tullacondra by Group Eleven, near PG West Project, Ireland
The Company recently completed its maiden drill hole G11-3535-01 at Tullacondra (totalling 145.5m, collar azimuth of 170° and dip -60°) located within the area of the historic estimate1, drilled between two historic holes collared approximately 100m apart north-south (see Exhibit 3 and 5).
The hole intersected 130.1m of 0.50% Cu and 20.8 g/t Ag (from 5.0m downhole depth; true width 60-90%), including 65.1m of 0.64% Cu and 29.5 g/t Ag (see Exhibit 4 and 6), representing the best hole drilled to date at the prospect (versus 106.4m of 0.56% Cu and 24.2 g/t Ag, historically; see Exhibit 7). A silver-rich portion of the interval measured 3.95m of 143.7 g/t Ag and 1.24% Cu (from 97.6m; true width 80%), including 0.20m of 639.0 g/t Ag and 4.54% Cu, representing the highest silver grade attained to date at the prospect (versus 426.1 g/t Ag, historically). A newly-identified zone of 13.2m grading 0.37% Cu and 16.3 g/t Ag (true width 80%) was intersected from 121.9m downhole, including a silver and copper-rich horizon of 0.40m of 303.0 g/t Ag and 5.37% Cu (highest copper grade to date at the prospect, versus 1.78% Cu, historically).
Bornite and chalcocite-tennantite dominate the centre of mineralized interval yielding the highest grades; whereas, the margins are dominated by chalcopyrite (see Exhibit 5). Most of the mineralisation is within bedding-parallel veins, albeit, some veins are cross-cutting at nearly right angles. The average dip of the main veins is estimated at 60°. Separately, weakly anomalous levels of cobalt were also returned in the assay results, assumed to be of little significance at this time.

Exploration Potential at Tullacondra Prospect, Near PG West Project, Ireland
Although historic intercepts at the currently defined edges of the historic estimate1 at Tullacondra appear to show the mineralizing system waning, the mineralized body nevertheless remains open in most directions (see Exhibit 3). Strong potential also exists to find look-alike bodies elsewhere on the property, especially in areas of similarly intense east-west faulting.
The mineralized body at Tullacondra is predominantly hosted within the Lower Limestone Shales and the Ballysteen Limestones (see Exhibit 5), however, the newly identified zone (13.2m of 0.37% Cu and 16.3 g/t Ag) occurs within the typically less explored Old Red Sandstone (“ORS”) horizon. While other intercepts of ORS-hosted Cu-Ag mineralization exist on the property, they are rare (only a few) and weaker than the above intercept. This opens the possibility that (a) much of the historic drilling was not drilled sufficiently deep to intersect this target (see hypothesized mineralization in Exhibit 5); and (b) further underexplored potential exists elsewhere on the property to discover ORS-hosted mineralization, proximal to faulting. Interestingly, two historic holes drilled 470m apart and over 300m to the south of the southern edge of the mineralized body interested 42.7m of 0.14% Cu (M-73-23) and 9.2m of 0.17% Cu (M-73-25), respectively. Both of these intercepts were hosted within the ORS and increasingly proximal to the east-west axis of the Tullacondra antiform (see Exhibit 2).
Zinc potential also exists at Tullacondra within the Waulsortian Limestone which is preserved on the property (see Exhibit 2) and underlain by stratigraphically-lower, copper-bearing horizons. Overall, follow-up drilling at Tullacondra is strongly warranted. The Company aims to provide an update over the near-medium term on the potential next phase of exploration at the project.
