Juno Corp. Commences Large Drilling Program in the Ring of Fire – Ontario Recognizes High-Purity Iron as a Critical Mineral

Press Release

Toronto, Ontario – March 5, 2026 – Juno Corp. (“Juno” or the “Company”), the largest mineral claimholder and most active explorer in Ontario’s Ring of Fire, is pleased to announce that drilling has officially commenced on the Company’s 2026 exploration program – what Juno believes to be the largest drilling campaign in the Ring of Fire in over a decade. The Company also acknowledges the Ontario government’s decision to add high-purity iron and aluminum to Ontario’s Critical Minerals List, a significant development that directly aligns with Juno’s Vespa critical minerals discovery.

“This is a transformational moment for Juno and for the Ring of Fire,” said Robert Cudney, Founder, Director & CEO of Juno Corp. “With drills now turning on what we believe to be the largest exploration program this region has seen in decades, we are building on the exceptional discoveries at Big Thunder and Vespa. The simultaneous advancement of a district-scale gold system and a uniquely enriched critical minerals complex is rare in exploration – and we are just getting started.

The inclusion of high-purity iron on Ontario’s Critical Minerals list is a bold and forward-thinking step that underscores its vital role in clean steel production, advanced manufacturing and next-generation technologies. Discoveries such as Juno’s Vespa system demonstrate the potential of the Ring of Fire to anchor secure, made-in-Ontario supply chains for iron, titanium, vanadium, scandium and gallium — the very materials that will drive innovation, strengthen our industrial competitiveness, and power Ontario’s economy for generations,” said Robert Cudney.

Highlights:

⦁ Drilling has commenced on Juno’s fully funded 2026 exploration program, with a minimum budget of $20 million dedicated to advancing two flagship district-scale discoveries: Big Thunder (high-grade gold) and Vespa (high-grade critical minerals)

⦁ 100 drill holes planned across ~28,000 metres – 50 holes at Vespa (~13,000m) and 50 holes at Big Thunder (~15,000m)

⦁ Ontario adds high-purity iron and aluminum to its Critical Minerals List, which supports the strategic significance of Juno’s Vespa V-Ti-Fe-Sc-Ga discovery in the central Ring of Fire

⦁ Winter road is now open and Juno has successfully mobilized equipment and personnel to its Ring of Fire operations

⦁ Vespa maiden mineral resource targeted with 44 mineral resource-definition holes and 6 exploration holes planned;

⦁ Ring of Fire development momentum accelerating – Wyloo’s Eagle’s Nest nickel project cleared a major federal regulatory milestone, and road infrastructure continues to advance with Webequie and Marten Falls First Nations

⦁ Juno’s land position now totals 29,956 claims covering approximately 5,796 km² – the size of the Greater Toronto Area – making Juno the largest mineral claimholder in the Ring of Fire

Drilling Commenced – 2026 Program Underway

Following the Company’s January 19, 2026 announcement detailing its fully funded 2026 exploration program, Juno is pleased to confirm that drilling operations have now commenced. The winter road into the Ring of Fire is open and Juno has successfully mobilized drill rigs, equipment, fuel, and personnel to its operational base at Oval Lake Camp.

Three drill rigs are planned for deployment between Big Thunder (gold) and Vespa (critical minerals).

At Big Thunder, the Company plans 50 holes totalling approximately 15,000 metres across the Pluto and North Edge, areas. Priority targets have been defined using a combination of previous drill results, AI and geochemistry-based soil targets, ground IP survey results, and structural analysis. Previous Big Thunder drill results include:

Big Thunder Gold District:*

⦁ PLU-24-001: 78.9 g/t Au over 3.9m from 104m depth including 370.0 g/t Au over 0.6m from 105m depth

⦁ PLU-24-007: 3.9 g/t Au over 16.0m from 297m depth including 15.8 g/t Au over 4.0m from 297m depth

⦁ NDG-24-002: 25.9 g/t Au over 2.3m from 19.5m depth including 72.9 g/t Au over 0.8m from 19.5m depth

At Vespa, the Company plans 50 holes totaling approximately 13,000 metres, including 44 mineral resource-definition holes and 6 exploration holes targeting AI-identified soil anomalies and magnetic inversion priority targets. Drilling is focused on the highest-confidence area with the objective of supporting calculation of a maiden mineral resource estimate.

Vespa Critical Minerals:*

⦁ VES-24-003: 103.0m grading 22.0% Fe, 4.33% TiO₂, 0.49% V₂O₅ from 62.0m, including 25.1m grading 48.7% Fe, 10.9% TiO₂, 1.23% V₂O₅ from 74.7m

⦁ VES-24-015: 71.8m grading 35.7% Fe, 8.22% TiO₂, 0.75% V₂O₅ from 12.2m, including 55.1m grading 43.3% Fe, 10.2% TiO₂, 0.93% V₂O₅ from 15.6m

⦁ Metallurgical testing confirmed 64–67% Fe concentrates with ~1.8% V₂O₅ and near-70% TiO₂ concentrates

Discovers Extensive Critical Minerals in the Ring of Fire” and “Juno Corp.

Ontario Recognizes High-Purity Iron as a Critical Mineral

The Company acknowledges the Ontario government’s announcement to add high-purity iron and aluminum to Ontario’s Critical Minerals List as part of the renewal of the Province’s Critical Minerals Strategy. This recognition directly aligns with Juno’s Vespa discovery, which hosts high-grade high-purity iron alongside vanadium, titanium, scandium, and gallium – minerals essential to clean steel production, aerospace manufacturing, battery technologies, and next-generation industries.

This addition follows the Government of Canada’s inclusion of high-purity iron on the federal Critical Minerals List in 2024, further reinforcing the strategic importance of secure, domestic supply chains for these materials.

Ring of Fire Development Momentum

The Ring of Fire continues to gain significant momentum as a nationally strategic mineral district. On February 24, 2026, it was reported that the federal Impact Assessment Agency of Canada decided not to designate Wyloo’s Eagle’s Nest nickel project for a federal impact assessment, clearing a major regulatory hurdle for the proposed mine. Wyloo has indicated its feasibility study is substantially complete.

Road infrastructure into the Ring of Fire continues to advance, with Webequie First Nation and Marten Falls First Nation having both submitted provincial environmental assessments for access roads connecting their communities to the Ring of Fire and Ontario’s highway system. Webequie is targeting construction commencement as early as April 2026.

Winter Road Mobilization and Operational Readiness

Juno has also continued to work alongside experienced infrastructure and logistics providers to support operational readiness in the region. During the current winter road season, heavy equipment, supplies, and materials have been successfully mobilized to the Ring of Fire to support exploration activities and regional development. The

participation of Green Infrastructure Partners Inc. (GIP), recognized for their expertise in large-scale civil infrastructure and remote logistics, reflects the growing alignment between industry and infrastructure capacity as development momentum in the region accelerates.
