[8-K] Contango Silver & Gold Inc. Reports Material Event

Rhea-AI Filing Summary

Contango Silver & Gold Inc. entered a purchase and sale agreement to acquire 100% ownership of the Lucky Shot project in Alaska and effectively eliminate a 2% net smelter returns royalty. Total consideration is $16,074,000, including a $10 million promissory note.

The cash component includes a $300,000 deposit, $1,709,250 paid at signing, and $4,064,750 due at closing expected by July 1, 2026. The secured note bears 5% annual interest, with $2 million principal payments on the second and third anniversaries of closing and the balance due by May 4, 2030.

Contango also reported high‑grade underground drill results from the 2025/2026 program at Lucky Shot, with intervals such as 2.89 meters grading 16.06 g/t gold and 0.50 meters at 74.20 g/t gold. To date, 6,020 meters in 65 holes have been completed, with about 12,000 meters of additional drilling and 800 meters of new underground development planned to support a resource update and feasibility study targeted for the first half of 2027.

Insights

Mining equity analyst

Contango expands control of Lucky Shot and reports high-grade gold drilling.

Contango Silver & Gold is consolidating its interest in the Lucky Shot project by purchasing the underlying real property, mining claims, equipment, and the lease from Alaska Hardrock Inc., effectively removing a 2% net smelter returns royalty burden.

The $16,074,000 consideration blends near-term cash outlays with a $10M note at 5% interest, amortizing with $2M installments in years two and three and a final payment by May 4, 2030. This structure staggers cash commitments while securing long-term project control.

Drilling results from 6,020 meters in 65 holes include multiple high-grade intercepts, such as 2.89 meters at 16.06 g/t gold and 0.50 meters at 74.20 g/t. Planned 12,000 meters of further drilling, 800 meters of underground development, and a feasibility study targeted for H1 2027 indicate an intensive de-risking and evaluation phase, though future economics will depend on subsequent technical work and market conditions.

Key Terms

6 terms

net smelter returns royalty financial

"includes a 2% net smelter returns royalty (the “NSR Royalty”) payable to AHI"

A net smelter returns (NSR) royalty is a contractual right to receive a percentage of the revenue generated from mined minerals after the ore has been processed and sold, with common deductions for refining, smelting and transport costs. Think of it like a landlord taking a slice of a tenant’s monthly sales after the tenant pays basic operating bills. Investors care because an NSR affects the future cash flow and valuation of a mining project and shifts some upside and downside risk away from the operator to the royalty holder.

Promissory Note financial

"executed a promissory note (the “Promissory Note”) with Alaska Hardrock Inc."

A promissory note is a written IOU in which one party promises to pay a specific sum, often with interest, to another party by a set date or on demand. Investors care because it functions like a loan: it creates a legal claim on future cash flows, carries credit and timing risk, and can affect valuation or liquidity—think of it as a formal, tradable promise to be repaid that can be assessed like any other debt investment.

PhotonAssay technical

"Gold analyses for mineralized intervals were completed using a two-cycle PhotonAssay™ method"

Photonassay is a laboratory method that measures metal concentrations by bombarding a rock or ore sample with high-energy photons and detecting the characteristic radiation the sample emits in response. For investors, it offers a faster, non-destructive way to estimate metal grades on bulk samples—like using a CT scan instead of slicing a loaf—helping produce more representative resource estimates, though results depend on proper calibration and the specific metals tested.

Qualified Person regulatory

"reviewed and approved by Dave Larimer, CPG, Vice President, Exploration for Contango, who is a Qualified Person"

A qualified person is someone with specialized knowledge, experience, and training in a particular field, allowing them to accurately assess and verify information or work. Their expertise helps ensure that reports, evaluations, or decisions are trustworthy and meet required standards. For investors, a qualified person provides confidence that the information they rely on is credible and properly validated.

Feasibility Study financial

"advance technical studies in support of a mineral resource update and feasibility study targeted for H1 2027"

A feasibility study is an assessment that evaluates whether a proposed project or idea is practical and likely to succeed before investing significant time and resources. It considers factors like costs, potential benefits, and challenges, helping stakeholders decide if moving forward makes sense. Think of it as a detailed plan that gauges if a new venture is worth pursuing.

Regulation S-K 1300 regulatory

"conducted in accordance with industry’s best practices and applicable SEC S-K 1300 requirements"

A U.S. securities regulation that sets clear standards for how mining companies must describe exploration results, mineral resources and mineral reserves in public filings. It requires consistent categories, supporting data and professional qualifications so investors can compare projects reliably, much like a standardized report card that reduces the risk of overstated claims and helps assess the value and uncertainty of a mining asset.

Item 1.01 Entry into a Material Definitive Agreement.

On May 4, 2026, Contango Lucky Shot Alaska, LLC (“LSA”), a wholly-owned subsidiary of Contango Silver & Gold Inc. (“Contango” or the “Company”), entered into a purchase and sale agreement (the “Purchase Agreement”) and executed a promissory note (the “Promissory Note”) with Alaska Hardrock Inc. (“AHI”) to acquire 100% ownership of the Company’s Lucky Shot project, located in the Willow Mining District about 75 miles north of Anchorage, Alaska (“Lucky Shot”). Pursuant to the Purchase Agreement, the Company purchased from AHI the underlying real property, mining claims and mining equipment. 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”); and

•Promissory Note of $10 million.

The Company is required to pay interest on the outstanding principal balance of the Promissory Note annually on the anniversary of the Closing Date at a rate of 5%, compounded monthly. Principal repayments of $2,000,000 are due on the second and third anniversaries of the Closing Date, with the remaining principal balance due on the fourth anniversary of the Closing Date, or May 4, 2030. The Promissory Note is secured by real property, mining claims, and other assets acquired by LSA from AHI.

As additional consideration of the Purchase Agreement, AHI assigned its rights as the lessor under the Lucky Shot lease agreement (the “Lease Agreement”), which includes a 2% net smelter returns royalty (the “NSR Royalty”) payable to AHI, to LSA. Post-assignment, LSA will be both the lessor and the lessee under the Lease Agreement. Thus, although the Lease Agreement was not terminated (due to remedies available to AHI in an event of default as defined in the Promissory Note), the 2% NSR Royalty contained in the Lease Agreement was effectively terminated from an economic perspective.

Exhibit 99.1

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

Exhibit 99.1

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 . 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.

Exhibit 99.1

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

Exhibit 99.1

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.
