Rick Van Nieuwenhuyse, Chief Executive Officer, stated: “Our latest drilling at Lucky Shot has exceeded expectations, providing a better understanding of the system’s continuity and productivity. The presence of visible gold in multiple intervals is a powerful indicator of the high-grade nature of this deposit. By confirming these multiple vein structures, we have significantly expanded the underground footprint while continuing to de-risk the project. This is not just additional drill and assay data; it is a roadmap to expansion. These assays provide the critical momentum we need to accelerate our technical work and unlock the substantial scale we see inherent in this project.”

Acquisition of Underlying Lucky Shot Lease and Royalty

On May 4, 2026 the Company entered into a purchase and sale agreement (the “Purchase Agreement”) with Alaska Hardrock Inc. (the “Seller” or “AHI”) to acquire 100% ownership of its Lucky Shot project by purchasing from AHI the underlying real property, mining claims and mining equipment and extinguishing the outstanding 2% net smelter returns royalty (the “NSR Royalty”) held by AHI. The consideration totaled $16,074,000, comprised of the following:

  • Cash deposit of $300,000 (paid)
  • Cash payment of $1,709,250 due on signing of the Purchase Agreement (paid)
  • Cash payable of $4,064,750 due on closing, which is expected to occur no later than July 1, 2026 (the “Closing Date”)
  • Promissory note of $10 million:
    • 5% annual interest rate compounding monthly, payable annually
    • Principal repayments of $2,000,000 on the second and third anniversary dates of the Closing Date with the remaining principal balance due on the fourth anniversary of the Closing Date
    • Secured by real property, mining claims, and other assets acquired

Highlights of this transaction:

  • Restores full value and control of the Lucky Shot project

“Contango has successfully consolidated the royalty interests at Lucky Shot, a move that significantly enhances the project’s overall value,” said Rick Van Nieuwenhuyse, CEO. “It is a rare and exciting milestone for an operator to acquire the surface and subsurface royalty interests, effectively streamlining our cost structure. This investment allows us to move into the feasibility stage with a highly efficient operating profile, keeping the project’s full potential firmly in the hands of our investors.” 

Closing of the transaction is subject to customary closing conditions.

Detailed Discussion of Drill Results

The Lucky Shot 2025/2026 underground drilling program began in November 2025. To date, the Company has completed 65 HQ diamond drill holes totaling 6,020 meters from ten underground drill stations located along the West Drift (Figure 1). Drilling was completed from existing underground infrastructure, allowing for accurate targeting of known vein structures and improved drill orientation control. The program is focused on the historically mined Lucky Shot Vein (L2 Vein) and the associated L1b, L1c, and L1d veins, which remain historically undeveloped. This release follows the Company’s initial drill results announced on March 2, 2026, titled “Contango Ore Intersects 60.22 g/t Gold over 5.92 meters, including 294.77 g/t Gold over 1.16 meters from Underground Drilling Program at the Lucky Shot Project, Alaska, USA.” This release includes the next group of assays received from four additional drill stations and 20 drill holes.

Program Highlights

  • Safe and successful continuation of underground drilling through Alaskan winter operating conditions.
  • Completion of 6,020 meters in 65 HQ diamond drill holes from ten underground drill stations.
  • Confirmation and extension of mineralization within the Lucky Shot vein system, including the L2, L1b, L1c, and L1d veins.
  • Identification and drill confirmation of previously unmodeled mineralized structures now designated as the L1e and CK veins.
  • Identification and interpretation of a post-mineralization structure, designated the Intersection Fault, that offsets portions of the Lucky Shot vein system.

Drill Results

Drilling continued eastward along the West Drift through successive underground drill stations (Figure 1). Drill fans were designed to test the down-dip and along-strike continuity of the historically mined L2 Vein (Lucky Shot Vein), while also testing the underlying L1b, L1c, and L1d veins. These underlying veins were included in the Company’s May 2023 S-K 1300 Technical Report Summary but remained more loosely constrained by drilling and had not been demonstrated to be laterally continuous at resource-model confidence.  This program was intended, in part, to test the continuity of these other subparallel veins.

Figure 1. Map showing the completed and planned underground drilling of the Lucky Shot (L2) Vein from the West Drift underground development.

Drill stations 489, 514, 538, and 563 tested areas of the L2 Vein that were not previously modeled due to limited drill coverage. This portion of the program successfully intercepted the projected L2 Vein position down dip of historical workings and extended interpreted lateral continuity eastward along strike. Drill highlights from the L2 Vein include:

  • LSU26069: 0.88 m averaging 6.69 g/t Au from 68.23 m depth
  • LSU26063: 1.15 m averaging 16.47 g/t Au from 96.90 m depth
  • LSU26064: 1.28 m averaging 27.86 g/t Au from 72.10 m depth

In addition to testing the modeled L2 Vein, drilling evaluated the lateral continuity of subparallel and related vein structures previously identified as the L1b, L1c, and L1d veins. Current geologic modeling suggests that the L1c and L1d veins are subparallel to the primary L2 structure. The L1b vein and newly modeled L1e vein are interpreted as lower-angle relay or ramp structures developed between the L2 and L1c veins (Figure 2). Gold mineralization is persistent across several of these structures, and visible gold was observed during core logging in multiple intervals.

Detailed underground mapping and core logging identified an additional gold-mineralized structure now designated as the CK Vein. The CK Vein was recognized near the intersection of the West Drift and the Enserch Tunnel and has a similar east-west strike and shallow northerly dip to the Lucky Shot system. Underground grab samples returned gold values including 6.5 g/t gold over 1.5 meters. The CK Vein was intercepted in most holes from these four drill stations, with visible gold observed in several logged intervals.

The additional drilling materially improves the Company’s understanding of the structural architecture and vein stacking within the Lucky Shot system. Detailed structural logging and underground mapping have identified a high-angle, post-mineralization structure designated as the Intersection Fault (Figure 2). This fault cuts the Lucky Shot vein system and is interpreted as a normal fault that down-drops the northwest block; the amount and sense of any lateral displacement remain under evaluation. The Intersection Fault was not encountered in the first four drill stations previously reported but was prevalent in the four drill stations reported in this release. The presence of multiple stacked and relay-oriented mineralized structures, together with the previously announced KM veins and the modeled Intersection Fault, supports additional exploration potential within the underground footprint. Future drilling (approximately 12,000 meters) will focus on refining structural orientations, continuity, and grade distribution across these emerging targets.

* Visible gold observations are qualitative geological observations made during core logging. The presence of visible gold does not necessarily indicate higher gold grades, mineral continuity, metallurgical performance, or economic significance. Gold assay results are derived from laboratory analysis and are the only quantitative measure of gold content. All drill core was systematically logged for visible gold; blank entries indicate no visible gold observed. Note: Reported intervals are downhole core lengths. True widths are not known at this time and may vary depending on vein orientation and drill-hole geometry.  Unless otherwise stated, no grade capping has been applied.

Quality Assurance and Quality Control

Contango’s drilling and sampling programs are conducted in accordance with industry’s best practices and applicable SEC S-K 1300 requirements. All drill core is systematically logged, photographed, and sampled under the supervision of the Company’s Qualified Person.

Quality assurance and quality control (“QA/QC”) procedures include the regular insertion of certified reference materials, blanks, and duplicate samples into the analytical stream at a frequency of approximately one QA/QC sample per ten samples. Mineralized intervals are sampled as whole core, with half-core shoulder samples extending approximately 5 meters on either side of mineralized zones. Samples are sealed and transported under documented chain-of-custody procedures to the laboratory.

Analytical testing was performed by Bureau Veritas North America, with sample preparation conducted in Fairbanks, Alaska. Gold analyses for mineralized intervals were completed using a two-cycle PhotonAssay™ method by Paragon Geochemical in Vancouver, British Columbia. The published lower limit of detection for the two-cycle PhotonAssay method is 0.015 g/t Au. All samples also undergo multi-element ICP-MS analysis (Bureau Veritas analytical code MA200) to quantify minor and trace element associations.

Upcoming Underground Exploration Development Work at Lucky Shot

With the successful completion of the initial phase of underground drilling at the Lucky Shot Project, Contango is now preparing to advance the next major phase of work: additional underground development. This development program represents an important operational step in advancing Lucky Shot, as it will provide the underground access and drill platforms required to continue testing and expanding the known mineralized system.

The planned development program consists of approximately 800 linear meters of underground excavation. Contango has selected GMS Mine Repair & Maintenance, Inc. (“GMS”) as the mining contractor for this work. GMS is a leading mining and tunneling contractor with more than 40 years of experience serving underground mining operations across North America.

The underground exploration development program is expected to commence in mid-May 2026 and is currently anticipated to take approximately five months to complete. As shown in Figure 3, the development has been designed to provide strategic underground access for the next phase of approximately 12,000 meters of drilling. This work is considered critical to the Company’s ongoing exploration and technical-study strategy to support completion of a Feasibility Study at Lucky Shot in H1 2027, as it will allow Contango to follow up on encouraging initial drill results, test additional priority targets, and continue advancing the geological model of the Lucky Shot mineralized system.
