Group Eleven Intersects 3.30 metres of 13.6% ZnEq in 220-metre step-out hole at Ballywire Zinc Prospect, PG West Project, Ireland
Vancouver, Canada, September 07, 2021 - Group Eleven Resources Corp. (TSX-V: ZNG; OTC: GRLVF; FRA: 3GE) (“Group Eleven” or the “Company”) is pleased to announce that a recent 220-metre step-out hole drilled at the Ballywire zinc prospect (“Ballywire”) at its 100%-owned PG West project (“PG West”), Ireland, intersected 3.30 metres of 13.6% zinc-equivalent (“ZnEq”) within a wider (>36-metre) mineralized intercept. This hole represents by far the best results to date at Ballywire and suggests immediate exploration potential over several kilometres in all directions, most notably to the north and west.
- G11-468-1 intersected 3.30 metres of 10.1% zinc, 2.4% lead (12.5% combined) and 48.3 g/t silver (13.6% ZnEq), including massive sulphides, starting at 312-metres downhole, within a wider (>36-metre) mineralized interval at the base of the Waulsortian limestone (true width is estimated at 83%)
- This intercept represents a 220-metre step-out to the NNW from historic drilling
- Mineralization is open for several kilometres in all directions, most notably to the north and west
- Significant zinc mineralization is now intersected in four consecutive holes defining a 900-metre long down-dip extent along the base of the Waulsortian limestone, along an NNW direction
- Importantly, the next nearest hole testing the target horizon is located over one kilometre to the WNW of G11-468-1 and hosts the second-best intercept at Ballywire (2.50 metres of 6.2% ZnEq, including 0.50 metres of 20.3% ZnEq), identifying the intervening area as highly prospective and warranting immediate follow-up
- Regionally, Ballywire is at the intersection of the Rathdowney Trend (which hosts Lisheen and Galmoy historic zinc mines1) and the Pallas Green Corridor (hosting Glencore’s Pallas Green zinc deposit2)
- The Company’s Carrickittle prospect is located approximately 10 kilometres to the NW of Ballywire, along the Pallas Green Corridor
“This is a significant breakthrough in the Company’s comprehensive search for a new zinc deposit in Ireland,” stated Bart Jaworski, CEO. “The above results demonstrate that significant mineralization exists at Ballywire and that scant historic drilling which managed to intersect mineralization, could now be interpreted as potentially being on the margins of a larger, more robust system. Mineralization is now consistently observed over 900 metres down-dip and is open in all directions. The next nearest hole testing the target horizon is located one kilometre to the WNW of today’s intercept and is strongly mineralized. This suggests a very prospective intervening area towards the shallowest part of the system. Today’s results catapult Ballywire into the same league as our Carrickittle prospect in terms of exploration potential, warranting immediate follow-up.”
Drill Results from Ballywire Zinc Prospect at PG West Project, Ireland
G11-468-1 (azimuth of 360°, dip of -80°, total depth of 361.0 metres) intersected 3.30 metres of 10.1% zinc, 2.4% lead (12.5% combined) and 48.3 g/t silver (13.6% ZnEq), starting at 312-metres downhole, at the base of the Waulsortian limestone (true width is estimated at 83%; see Exhibit 1). The intercept consists of semi-massive to massive sulphides (predominantly sphalerite, galena and pyrite).
Exhibit 1. High-Grade Drill Results from G11-468-1 at Ballywire Zinc Prospect, PG West Project, Ireland
|From||Int||Zn||Pb||Zn+Pb||Ag||Cu||ZnEq||% x m||Lithology|
|312.70||0.80||13.55||3.27||16.82||67.8||0.02||18.37||14.7||Semi- to massive sx|
|315.25||0.30||13.20||4.47||17.67||59.5||0.04||19.09||5.7||Semi- to massive sx|
Note: As a percent of the drilled interval, true thicknesses are estimated to be 83%; “ZnEq” combines Zn, Pb, Ag and Cu into a single number and is calculated from metal prices (US$) as follows: $1.00/lb Zn, $1.00/lb Pb, $15.00/oz Ag and $3.00/lb Cu; “sx” means sulphide;
The above intercept was hosted within a wider, lower-grade interval totalling 36.65 metres of 1.75% ZnEq, including 7.07 metres of 6.76% ZnEq (see Exhibit 2). The wider interval starts 33.25 metres above the base of the Waulsortian limestone and extends 3.40 metres below the base.

Note: As a percent of the drilled interval, true thicknesses are estimated to be 83%; “ZnEq” combines Zn, Pb, Ag and Cu into a single number and is calculated from metal prices (US$) as follows: $1.00/lb Zn, $1.00/lb Pb, $15.00/oz Ag and $3.00/lb Cu;
G11-468-01 represents a 220-metre step-out to the NNW from historic drill hole 00-468-5, which intersected up to 430 g/t silver and 1.89% copper over narrow widths within a wider, lower grade interval (see Exhibit 3, 4 and 5). Together with FM-2654-1 and the Company’s prior hole G11-2654-01 (announced on May 7th, 2019), the above holes define a 900-metre down-dip extent of significant mineralization (see Exhibit 3 and 4).
Five historic holes to the immediate west of the above were drilled over a number of years (from 1973 to 2000), but each encountered poor ground conditions and was not successful in reaching the target horizon. Hence, this area remains prospective and untested. Two holes further to the west and NW (97-468-2 and 98-468-3) were successful in reaching the target horizon and attained significant mineralization – most notably 97-468-2 which intersected 2.5 metres of 6.2% ZnEq (incl. 0.50 metres of 20.3% ZnEq) (see Exhibit 3, 4 and 5). The vicinity of this area, especially towards G11-468-1, is now deemed very prospective and warrants immediate follow-up.

Location and Importance of Rathdowney Trend
Ballywire is located at the Company’s 100%-owned PG West project (“PG West”), within the Limerick region of south-western Ireland and is situated at the intersection of the Pallas Green Corridor (NW-oriented) and the Rathdowney Trend (WSW-oriented; (see Exhibit 6). The Rathdowney Trend hosts the Lisheen1 and Galmoy2 zinc mines (both mined out in 2015 and 2012, respectively), located approximately 55 km and 65 kilometres towards the NE along trend from Ballywire.

Notes to Exhibit 6: (a) Pallas Green MRE is owned by Glencore; (b) Stonepark MRE: please refer to the NI 43-101 Independent Report on the Zinc-Lead Exploration Project at Stonepark, County Limerick, Ireland, with an effective date of April 26, 2018, as found on SEDAR; (c) the historic estimate at Denison was reported by Westland Exploration Limited in 1988, the historic estimate at Tullacondra was reported by Munster Base Metals Ltd in 1973 and the historic estimate at Gortdrum was reported by G.M. Steed in 1986; these 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.
Update on Carrickittle and Other Exploration
Drilling and the ground magnetic survey at Carrickittle are progressing on schedule. The Company aims to provide an update on Carrickittle over the coming few weeks. Drilling at Oola and Denison (both at PG West) is now complete with results to be published upon receipt of assays and geological interpretation.

Quality Assurance/Quality Control (QA/QC) Information
Drill-core samples were prepared and assayed in the ALS Minerals Laboratory in Loughrea, Ireland. Samples were fine-crushed (CRU-31) to 70% < 2mm and pulverized and riffle-split to 85% < 75 µm. Zinc, lead and silver assays were obtained by multi-acid (4-acid) digestion/ICP-MS Package (48 Elements), with ore-grade samples analysed using multi-acid ICP-AES. Analytical accuracy and precision are monitored by the submission of 2 standards and 2 blanks inserted into the sample train of 57 samples by Group Eleven personnel. ALS analysed 4 blanks, 7 duplicates and 14 standards as part of their internal QC procedures.
