Group Eleven Commences Drilling at Carrickittle West

Vancouver, September 12, 2024 - Group Eleven Resources Corp. (TSXV: ZNG) (OTC Pink: GRLVF) (FSE: 3GE) ("Group Eleven" or the "Company") is pleased to announce that it has commenced drilling at the Carrickittle West Prospect ("Carrickittle West"), Republic of Ireland. The prospect spans across the Company's 76.56%-owned Stonepark Project ("Stonepark") and the Company's contiguous 100%-owned PG West Project ("PG West"). The Company also provides an update on its Ballywire discovery.

Stonepark - Targeting Another Significant Zinc Discovery at Carrickittle West

• Drill program of 4-5 holes at Carrickittle West totalling approx. 1,700m (hole depths of 350m to 550m) testing the southern margin of the Limerick Volcanic Complex ("LVC"), a prospective area of approximately 11km in strike-length
• Targets include areas of brecciation and mineralization seen in previous drilling, the Kilteely volcanic centre and the SW extensions of the Coonagh Castle Fault (first intersected by Group Eleven, see news release dated 16-Jun-2022)
• Volcanic centre at Kilteely, covering 2km x 6km, is the focus of renewed attention by the Company given its potential association with zinc mineralization - the only other interpreted volcanic centre in the LVC is located adjacent to the Pallas Green deposit¹ (only 5km north of Carrickittle West)

Ballywire - Next Drill Results Imminent on Growing Zinc-Lead-Silver Discovery

• The two-rig drill program at the Ballywire discovery at PG West is progressing well
• Ballywire drilling this year now totals 5,880m (including 3,475m reported to date and eight holes pending assay results), with the total for the year expected to range from 7,000m to 8,000m
• Next assay results are expected to include three holes from NE step-outs (G11-3552-15, -16 and 17) and one hole from a SW step-out (testing the 'B' gravity anomaly; G11-2654-03)

"We are excited to start our long-awaited follow-up drill program at the Carrickittle West prospect," stated Bart Jaworski, CEO. "This program aims to provide us with critical information needed to further unlock value on this 'Pallas Green lookalike' target and hopefully make another discovery. At Ballywire, we look forward to providing the market with new drill results shortly. As stated previously, work announced to date suggests Ballywire is increasingly showing signs of a major zinc-lead-silver discovery."

Notes to Exhibit 3: (a) Pallas Green MRE is owned by Glencore (see Glencore's Resources and Reserves Report dated December 31, 2023); (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 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.
