Drill Results

Group Eleven Drills 23.5m of 12.3% Zn+Pb and 46 g/t Ag,

Further Confirms Deeper Cu-Ag Mineralization and

Extends Mineralized Strike by 600m to 3.2km

Vancouver, Canada, April 16, 2026 - Group Eleven Resources Corp. (TSX-V: ZNG; OTCQB: GRLVF; FRA:

3GE) (“Group Eleven” or the “Company”) is pleased to announce new assay results from its Ballywire

discovery (“Ballywire”) at the 100%-owned PG West Project (“PG West”), Republic of Ireland.

Highlights:

• 25-3552-53 – Extends previous interval from 25-3552-51 announced on 19-Jan-2026, totalling

29.9m of 15.3% Zn+Pb, 552 g/t Ag and 0.67% Cu (from 338m downhole, at base of Waulsortian

Limestone), downdip and to the SE along two zones:

▪ Waulsortian Limestone hosted (40m extension from 25-3552-51)

▪ 57.3m of 6.2% Zn+Pb (3.4% Zn and 2.8% Pb), 35 g/t Ag (from 322m downhole), incl.

▪ 23.5m of 12.3% Zn+Pb (6.2% Zn and 6.1% Pb), 46 g/t Ag, incl.

• 11.3m of 17.6% Zn+Pb (8.2% Zn and 9.4% Pb), 60 g/t Ag, incl.

• 4.7m of 27.6% Zn+Pb (15.7% Zn and 11.9% Pb), 92 g/t Ag, incl.

• 1.0m of 47.0% Zn+Pb (27.0% Zn and 20% Pb), 171 g/t Ag

• Deeper Cu-Ag Zone (70m extension from 25-3552-51)

• 7.5m of 22 g/t Ag and 0.79% Cu (starting from 582m downhole), incl.

• 3.5m of 35 g/t Ag and 1.28% Cu

• Assays from downhole intervals 379m to 579m and 593m to 609m are pending

• 25-3552-51 – Remaining assays from this hole returned three zones of mineralization from the

Deeper Cu-Ag target (starting from 434m downhole)

▪ 1.9m of 17 g/t Ag, 0.28% Cu and

▪ 1.8m of 59 g/t Ag, 0.61% Cu, 0.14% Sb and

▪ 2.8m of 30 g/t Ag, 0.72% Cu (incl. 1.0m of 78 g/t Ag, 1.91% Cu, 0.16% Sb)

• Cu-Ag mineralization announced today provides additional evidence of steeply south-dipping fault

zones, interpreted to be continuation of Cu-Ag bearing fault zones intersected 350m to the NE (in

holes 25 -3552-40, -44 and -47, announced in 2025 ), adding support to hypothesis that Cu -Ag

bearing fault zones may extend along strike length of entire Ballywire discovery

• 25-3552-52 – Extends mineralized strike length of the Ballywire discovery by approx. 600m from

2.6km to 3.2km, by intersecting 22m of mineralization hosting 2.8m of 3.3% Zn+Pb (3.2% Zn and

0.1% Pb), 16 g/t Ag, including 1.0m of 7.7% Zn+Pb (7.4% Zn and 0.3% Pb) and 38 g/t Ag

“Today’s results represent another major step forward in our understanding of the Deeper Cu -Ag

target at Ballywire,” stated Bart Jaworski, CEO. “ With significant Cu-Ag bearing fault structures now

pierced by five holes along two drill fences located 350m apart, we have increasing conviction that

Deeper Cu -Ag mineralization may extend across the entire discovery to date . Extending the

mineralized strike length of the discovery by 600m to 3.2km bodes well for our ongoing drilling along

our 6km prospective trend. Today’s impressive Waulsortian-hosted mineralization is also very

encouraging. With a robust treasury and our most ambitious drill campaign to date – recently

bolstered by our $12m financing allowing go -forward funded drilling to increase from 20,000m to

approx. 67,000-75,000m, we are poised to continue unlocking this discovery’s full potential.”

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 77 holes drilled and reported by Group Eleven to date, including the most

recent two new holes (25-3552-53 and -52) reported today. Today’s results from 25 -3552-51 are in

addition to partial assays announced on 19 -Jan-2026 and 25 -Feb-2026. All of today’s results are

summarized above and below (see Exhibits 1 to 5).

Mineralization reported today consists predominantly of sphalerite, galena and pyrite, with Cu -Ag

bearing zones also containing chalcopyrite and locally, suspected tennantite-tetrahedrite.

Hole 25-3552-52 was a significant step-out hole drilled approx. 350m ENE of its nearest drill hole (see

Exhibit 2), on the far east portion of the Ballywire discovery. This hole returned robust mineralization

totalling 2.8m of 3.3% Zn+Pb (3.2% Zn and 0.1% Pb) and 16 g/t Ag, including 1.0m of 7.7% Zn+Pb (7.4%

Zn and 0.3% Pb) and 38 g/t Ag (see Exhibits 2 and 3). Relative to the nearest significantly mineralized

hole (G11 -3552-08), this hole expands the strike-length of mineralization intercepted to date at

Ballywire by approx. 600m from 2.6km to 3.2km (see Exhibit 2).

Exhibit 5. Regional Gravity Map Showing 6km Long Prospective Trend at Ballywire

Note: Of the four gravity-high anomalies above, only the ‘C’ anomaly has been systematically drilled to date

Given the Company’s recent C$12.0m financing (closed 11 -Mar-2026), the go -forward funded drill

program has increased from 20,000m to between 67 ,000m and 75,000m (subject to detailed

planning), largely earmarked for Ballywire, with the remainder at Stonepark.

Four rigs continue to be actively drilling at Ballywire. Currently, eleven (11) 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 and 5, including: (i) three holes collared on a fence at the SW extent of the

discovery; (ii) two holes stepping out approx. 100m SW from today’s drill fence; (iii) three holes drilled

in a fan pattern immediately S W of G11-3552-08; (iv) one hole testing 300m NE of today’s 25-3552-

52, testing the ‘D’ gravity -high anomaly ; (v) one hole testing for parallel zones of mineralization

approx. 100m NNE of G11-3552-08 and (vi) one hole testing the ‘A’ gravity-high anomaly.

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 resour ce 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.

Stonepark Update

At the Stonepark Project (77.64% Group Eleven, 22.36% Arkle Resources plc), located contiguous to

the PG West Project, one hole (25 -449-04) was drilled late last year at the Bruff prospect (see

background information on Bruff and Kilteely prospects in news release dated 16 -Jun-2025). Drilled

to a depth of 480m , this hole tested the base of the Waulsortian Limestone near a suspected fault

structure. A significant zone of blocky calcite was intersected from 194m to 200m with a brecciated

lower contact , while minor disseminated pyrite was observed in the 10m above the base of the

Waulsortian Limestone at 445m. While assays (recently received) did not return anomalous grades,

the hole is encouraging as it shows a geological environment prospective for Irish-type zinc

mineralization (i.e. calcite zones, brecciation and sulphides).

Building on the above geological observations, the Company is mobilizing a rig to Stonepark this week,

supplementing the four rigs operating at Ballywire. A four -hole drill program totalling 2,700m is

planned, comprising: one hole at the Stonepark deposit testing beneath known Zn-Pb mineralization

for possible Cu mineralization; one hole at the Kilteely prospect; and two holes at or near the Bruff

prospect. Arkle Resources has elected not to participate in funding this program, with its interest in

the P roject estimated to decrease from 22.36% to 21.38% ( subject to cost actuals after fieldwork

completion). The Company aims to provide further information on this program later this year.
