Berliner Tageblatt - Juno's Vespa Critical Minerals Discovery Expands to Include Heavy Rare Earth Magnet Metals

TORONTO, ON / ACCESS Newswire / May 19, 2026 / Juno Corp. ("Juno" or the "Company") today announced the discovery of heavy rare earth elements - including the magnet metals essential to defence, aerospace, electric vehicles and clean energy - within its Vespa critical minerals system in Ontario's Ring of Fire. The discovery sits within the same geological system as Juno's previously announced high-grade iron, titanium, vanadium, scandium and gallium intercepts at Vespa, broadening the critical minerals discoveries.

"Rare earth magnet metals are the materials that build modern defence systems, fighter jets, electric vehicles and clean energy infrastructure. Global supply is dominated by a single country that has shown its willingness to use export controls as a tool of geopolitical leverage - making secure, allied sources of these metals a national priority for Canada, the United States and our partners," said Robert Cudney, Founder, Director and CEO of Juno Corp. "We believe that the Ring of Fire can be the cornerstone of the future of mining in Canada. This discovery places Juno's potential at the centre of that strategic opportunity."

"This is a major broadening of what Vespa is," said Jeremy Niemi, Chief Strategy Officer of Juno Corp. "We have identified the rare earth magnet metals the world is competing for, hosted in garnets sitting directly alongside our high-grade iron, titanium and vanadium discoveries. We believe that there is the strategic opportunity to recover these rare earths as a by-product of a future Vespa operation - there could be multiple critical metals from a single deposit."

Summary of Results:

• Heavy rare earth elements discovered within Juno's Vespa critical minerals system in the Ring of Fire

• Discovery includes the four key magnet metals - neodymium, praseodymium, dysprosium and terbium, as well as yttrium and other critical rare earths - essential to defence systems, aerospace, electric vehicles, wind turbines and robotics

• Initial rush assays returned a continuous 87-metre interval within a 200+ metre mineralized corridor, with 27% of total rare earths comprised of high-value heavy rare earths - an exceptional ratio

• Discovery is hosted within Juno's Vespa mineral complex, with potential to recover rare earths as a by-product of Vespa's iron, titanium, vanadium, scandium and gallium production - confirming Vespa as a true polymetallic critical minerals system

• Additional sampling, assays and metallurgical work are underway as part of Juno's fully funded 2026 Vespa drill program

To date, these results are the only results received at the Vespa project for 2026 drilling. VES-26-025 is the first hole drilled on Vespa in the 2026 program.

"TREO (Total Rare Earth Oxides) is calculated by multiplying the elemental concentration of each REE by its specific stoichiometric conversion factor. The conversion factors used are: La2O3 (1.1728), CeO2 (1.2284), Pr6O11 (1.2082), Nd2O3 (1.1664), Sm2O3 (1.1596), Eu2O3 (1.1579), Gd2O3 (1.1526), Tb4O7 (1.1762), Dy2O3 (1.1477), Ho2O3 (1.1455), Er2O3 (1.1435), Tm2O3 (1.1421), Yb2O3 (1.1387), Lu2O3 (1.1371), and Y2O3 (1.2699)."

Technical Notes

Assays referenced in this news release are initial rush assays from 76 samples and remain subject to confirmation by completion of the full assay program. Drill core was logged and sampled at Juno's Oval Lake Camp in the Ring of Fire. Blanks and Certified Reference Materials were inserted into the sample stream at appropriate intervals according to CIM Best Practices. Sampled core was split and sent to ALS Canada Ltd. Preparatory Lab in Thunder Bay. Core samples were crushed, pulverized, and split before being sent for assay determination. Samples were sent to ALS Vancouver for Multi-element Mass Spectrometer analysis (Code ME-MS81). ALS is independent of Juno. True widths of the reported intercepts are unknown at this time. For further details on previously reported Vespa drilling, please refer to the Company's press releases dated January 29, 2025 and March 5, 2026.
