GROUP ELEVEN REPORTS 94% HIGHER GERMANIUM GRADES, UP TO 155 G/T GE, AT BALLYWIRE WITH IMPROVED ACCURACY ASSAY METHOD

Group Eleven Resources Corp. has released results from a second batch of drill hole intervals reanalyzed using a new, higher-accuracy germanium assay method at its Ballywire discovery, part of the 100-per-cent-owned PG West project in Ireland. These results follow the company's related news release dated Sept. 17, 2026.

Highlights:

• What is germanium: Germanium (Ge) is a semiconductor used across several industries, including AI-related (artificial intelligence) infrastructure and fibre optics. Outside China, it currently trades at about $235 (U.S.) per ounce, up approximately 50 per cent from September, 2025, and up over 500 per cent since January, 2023. In the Earth's crust, elevated Ge grades typically occur only in some coal deposits and certain zinc deposits.
• New assay method: Over the past few years, 330 drill core samples from Ballywire were submitted for Ge analysis at ALS Laboratories in Ireland, using lithium borate fusion (old method), the most accurate assay method for Ge at the time. After recent discussions with ALS, it was recommended to try sodium peroxide fusion (new method) to increase digestion and minimize Ge loss to volatiles during the assay process, resulting in higher accuracy.
• New results: In addition to 220 samples (from five drill holes) announced on Sept. 17, 2026, a second batch of 110 samples has now been reanalyzed with the new method, returning Ge grades 94 per cent higher on average compared with the old method; results are as follows (note old-method results were previously published):
  • G11-3552-12 -- zinc-plus-lead and silver results announced June 11, 2024, with today's Ge results:
    • 2.8 metres of 9.8 per cent Zn+Pb, 24 grams per tonne Ag and 27 g/t Ge (previously 18 g/t Ge);
  • G11-3552-17 -- Zn+Pb and Ag results announced Sept. 24, 2024, with today's Ge results as follows:
    • 1.4 m of 14.4 per cent Zn+Pb, 29 g/t Ag and 60 g/t Ge (previously 12 g/t Ge);
  • G11-3552-19 -- Zn+Pb and Ag results announced Nov. 14, 2024, with today's Ge results as follows:
    • 8.7 m of 23.9 per cent Zn+Pb, 85 g/t Ag and 43 g/t Ge (previously 15 g/t Ge);
  • G11-468-01 -- Zn+Pb and Ag results announced Sept. 7, 2021, with today's Ge results as follows:
    • 3.3 m of 12.5 per cent Zn+Pb, 48 g/t Ag and 44 g/t Ge (previously 27 g/t Ge);
  • G11-468-03 -- Zn+Pb and Ag results announced Sept. 6, 2022, with today's Ge results as follows:
    • 6.9 m of 15.4 per cent Zn+Pb, 160 g/t Ag and 38 g/t Ge (previously 19 g/t Ge);
    • 2.1 m of 40.8 per cent Zn+Pb, 385 g/t Ag and 93 g/t Ge (previously 48 g/t Ge);
  • G11-468-06 -- Zn+Pb and Ag results announced March 2, 2023, with today's Ge results as follows:
    • 2.5 m of 29.2 per cent Zn+Pb, 160 g/t Ag and 27 g/t Ge (previously 19 g/t Ge).

"Today's results represent more accurate and significantly improved germanium grades at Ballywire, reinforcing one of the discovery's key value drivers," stated Bart Jaworski, chief executive officer. "With several triple-digit g/t Ge values, up to 155 g/t Ge and typical ranges of 20 to 50 g/t Ge over wider intervals, coincident with high grades of zinc and associated metals, today's results are stronger than our recent updated Ge assays from September. Four rigs continue to be active at Ballywire. With a robust treasury and our most ambitious drill campaign to date totalling over 67,000 m fully funded, we are poised to continue unlocking this discovery's full potential."

Ballywire drill update

The Ballywire prospect at the company's 100-per-cent-owned PG West project in the Republic of Ireland represents the most significant mineral discovery in Ireland in over a decade. First announced in September, 2022, the discovery has 91 holes drilled (totalling 35,402 m) and reported by Group Eleven to date, including today's results from 12 previously released holes (reporting reassayed Ge grades). All of today's results are summarized above.

As noted above, 330 Ballywire drill core samples were previously analyzed for Ge by ALS Laboratories in Ireland using the old method. Of these, 220 samples announced on Sept. 17, 2026, comprised largely continuous sequences selected to assess wider intervals. Today's remaining 110 samples were collected during the earliest phase of Ge testing at Ballywire and were used mainly for spot testing. Hence, further Ge analysis is required across the remaining untested intervals of strong zinc mineralization.

Note, as with all metals reported to date at Ballywire, metallurgical test work has yet to be completed, and, therefore, metallurgical recoveries are not yet known. Globally, Ge is known to have a close chemical association with sphalerite (zinc-bearing mineral) and this appears to be corroborated at Ballywire with high Ge grades well correlated with high Zn grades.

Four rigs continue to be actively drilling at Ballywire. Currently, 18 new holes are completed (and in the process of being logged, sampled and assayed) or in the process of being drilled. The company has a robust treasury bolstered by a $12-million financing in March, 2026, fully financing a drill program totalling approximately 67,000 m (including approximately 51,500 m at PG West).

Sampling and analytical procedures

All core drilled at Ballywire is NQ (47.6 millimetres) and is cut using a rock saw. Sample intervals vary between 0.08 m to 1.19 m, with an average (over 110 samples) of 0.63 m. The half-core samples are bagged, labelled and sealed at Group Eleven's core store facility in Limerick, Ireland. Selected sample bags are examined by the qualified person. Transport is by an accredited courier service and/or by Group Eleven staff to ALS Laboratories in Loughrea, County Galway, Ireland. Sample preparation at the ALS facility comprises fine crushing 70 per cent less than two millimetres, riffle splitting and pulverizing up to 250 grams 85 per cent less than 75 micrometres. Analytical procedures are 34-element four-acid ICP-AES (codes ME-ICP61 and ME-OG62). For germanium, in the past, the company used the lithium borate fusion (ME-MS81) assay method but, as of this news release, switched to sodium peroxide fusion (ME-MS89L). Other than paying for a professional analytical service, Group Eleven has no relationship with ALS.

Quality assurance/quality control (QA/QC) information

Group Eleven inserts certified reference materials (CRMs or standards) as well as blank material to its sample stream as part of its industry-standard QA/QC program. The QC results have been reviewed by the qualified person, who is satisfied that all the results are within acceptable parameters. The qualified person has validated the sampling and chain-of-custody protocols used by Group Eleven. Drill data (dip, azimuth and depth) for today's release will be posted on Group Eleven's website in due course.
