High-grade Lucky Shot gold hit as Contango (NYSE: CTGO) ramps underground work
Rhea-AI Filing Summary
Contango Silver & Gold Inc. reported final assay results from the initial phase of its 2025/2026 underground diamond drilling program at the Lucky Shot project in Alaska and outlined the next phase of underground development work.
The completed first phase comprised 65 HQ drill holes totaling about 6,020 meters within a planned 18,000-meter underground and surface campaign. Results include several high-grade gold intercepts, highlighted by 0.17 meters grading 972.10 g/t gold in hole LSU26091 from the L1d Vein, plus additional strong intervals from the L1c, CK, L2 and other veins. Updated cross-sections and models show a more detailed and complex interpretation of the Lucky Shot vein system.
Contango has restarted underground exploration development with contractor GMS Mine Repair & Maintenance, which has advanced 43 meters toward a planned 800 meters of excavation over roughly five months. This work is intended to create access and drill platforms for about 12,000 meters of further underground drilling, supporting ongoing technical studies and work intended to inform a Feasibility Study at Lucky Shot targeted for H1 2027.

Negative
- None.
Insights
High-grade Lucky Shot intercepts advance Contango’s geological model and set up the next drilling phase.
Contango reports completion of 6,020 meters of underground drilling at Lucky Shot within a larger 18,000‑meter plan. Assays such as 0.17 meters at 972.10 g/t Au and multi-meter intercepts in several veins refine the understanding of this structurally controlled system.
Updated vein models and cross-sections suggest improved confidence in the geometry and continuity of key structures like the L2, L1c, L1d and CK veins. The company emphasizes that reported intervals are downhole lengths and true widths are not yet known, so economic implications remain uncertain based on this information alone.
Underground development of about 800 meters, with 43 meters already advanced, aims to position roughly 12,000 meters of follow-up drilling and support technical work intended to inform a Feasibility Study targeted for H1 2027. Actual project outcomes will depend on future drilling results, permitting, contractor performance and market conditions.

NEWS RELEASE
CONTANGO SILVER & GOLD
Contango Silver & Gold Intersects 972.10 g/t Gold at Lucky Shot and Continues Underground Exploration Development Program
FAIRBANKS, AK - (June 16, 2026) - Contango Silver and Gold Inc. (“Contango” or the “Company”) (NYSE American / TSX: CTGO) is pleased to announce final assay results from the initial phase of the Company’s 2025/2026 underground diamond drilling program at the Lucky Shot Project in Alaska. These results complete the initial underground drilling phase of Contango’s planned multi-phase 18,000-meter underground and surface exploration campaign at Lucky Shot.
The final assay results include several significant gold intercepts from the Lucky Shot vein system, highlighted by 0.17 meters grading 972.10 grams per tonne (“g/t”) gold (“Au”) in drill hole LSU26091, which intercepted the L1d Vein and included visible gold observed during core logging. The Company also announces that underground exploration development work has re-commenced at Lucky Shot, with our contract miner, GMS Mine Repair & Maintenance, Inc. (“GMS”) mobilized to site and is currently advancing exploration access and future underground drill platforms.
Select highlights from the final assay results include:
Rick Van Nieuwenhuyse, Chief Executive Officer of Contango, stated: “These assays complete the first phase of underground drilling at Lucky Shot and continue to highlight the high-grade potential and structural complexity of the system. The 972.10 g/t gold intercept in LSU26091 is an exceptional result and reinforces what our team has been seeing in core: visible gold, multiple mineralized vein structures, and a geologic model that continues to improve as drilling advances eastward toward the Enserch Tunnel. Just as importantly, we have now re-started underground exploration development, which is a critical step in establishing the access and drill platforms needed for the next phase of drilling and technical studies. I am particularly excited to continue to explore and test the very high grade KM vein, which intersected
approximately 6 meters grading 60 g/t encountered at the very end of the West Drift. By extending the West Drift 100 meters we will be able to test the extent and continuity of this very exciting new discovery.”
Final Assay Results Complete Initial Underground Drilling Phase
The 2025/2026 underground diamond drilling program was initiated in November 2025 from existing underground infrastructure along the West Drift. The initial phase of drilling is now complete and consists of 65 HQ diamond drill holes totaling approximately 6,020 meters. This phase was designed to test and refine the Company’s understanding of the Lucky Shot vein system, including the historically mined Lucky Shot Vein, also referred to as the L2 Vein, and multiple subparallel vein structures including the L1b, L1c, L1d, L1e, CK and KM veins (see figure 1).
Figure 1. Plan view of the Lucky Shot underground exploration development with completed drill holes from the initial phase of Underground drilling. Highlighted in red are the drill station with results in this release.
The final drill holes reported in this release completed fan drilling from the 587 and 612 drill stations and continued definition drilling across the Lucky Shot vein system eastward toward the Enserch Tunnel. The cross-sections shown in Figures 2 and 3 illustrate the Company’s updated interpretation of the Lucky Shot vein architecture across these drill stations and highlight the improved understanding of the complex, structurally controlled vein system. By tracking mineralized intercepts through successive drill fans from the previously reported drill stations into the current 587 and 612 drill stations, Contango has been able to
model the principal vein structures with improved geological confidence and better constrain their relative positions within the broader shear-vein system.

This work has improved the interpreted continuity and geometry of the Lucky Shot L2 Vein and several underlying subparallel vein structures, including the L1c, L1d and CK veins. The updated cross-sectional interpretation also supports a more coherent kinematic model for the vein system, helping to explain the spatial relationship between the historically mined Lucky Shot Vein, newly modeled vein structures, and observed high-grade gold intercepts. Detailed geological logging continued to identify visible gold in multiple intercepts, while updated modeling has refined the Company’s understanding of vein architecture, structural controls on mineralization, and follow-up target areas for the next phase of underground drilling.

Figure 4. Geological model comparison before this phase of drilling and current geologic understanding after. Figure 4a and B show the initial understanding of the Lucky Shot vein system at the end of 2023. Figure 4C and D are updated geologic vein models based on this program drilling.
Figure 4 provides a comparison of the Company’s prior model to the updated geological interpretation of the Lucky Shot vein system. Figures 4A and 4B show the earlier interpretation of the Lucky Shot vein model, which was constrained by a more limited drilling dataset and relied on broader correlation of vein intercepts across areas with less underground drill density. The narrow black lines shown in Figures 4A and 4B represent the previous interpreted vein surfaces supported by the drilling available at that time. Following completion of the initial phase of underground drilling, Figures 4C and 4D show the updated vein model, which incorporates the additional drill information collected from the West Drift program and reflects a more detailed interpretation of the structurally controlled mineralized system. The updated model better defines the geometry and relative position of the Lucky Shot L2 Vein and associated subparallel vein structures, while also highlighting the increased complexity of the vein architecture identified through this phase of drilling. This before-and-after comparison demonstrates how the additional drilling has improved the Company’s geological framework, increased confidence in the interpreted position of key vein structures, and provides a more robust basis for planning the next phase of underground drilling and exploration development.
The Company cautions that drill intercept lengths reported in this release are downhole core lengths. True widths are not yet known and may be materially different from reported interval lengths. Visible gold observations are qualitative geological observations made during core logging and do not necessarily correlate with 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.
Quality Assurance and Quality Control
Contango’s drilling and sampling programs are conducted in accordance with industry best practices and applicable SEC S-K 1300 requirements. All drill cores are systematically logged, photographed and sampled under the supervision of the Company’s Qualified Person.
Quality assurance and quality control procedures include the regular insertion of certified reference materials, blanks and duplicate samples into the analytical stream. Mineralized intervals are sampled as whole core, with shoulder samples extending beyond mineralized zones where appropriate. 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, and the upper detection limit is 355 g/t Au. Samples returning gold values above the upper detection limit are re-assayed using a 50-gram charge fire assay with gravimetric finish through Bureau Veritas. Samples also undergo multi-element ICP-MS analysis to quantify minor and trace element associations.
Commencement of Underground Exploration Development Work
Contango has commenced the next phase of work at Lucky Shot: underground exploration development designed to establish access and drill platforms for continued exploration of the Lucky Shot vein system. GMS mobilized to site on May 27, 2026, and has completed 43m of lateral advancement.
Contango selected GMS Mine Repair & Maintenance, Inc. as the mining contractor for the underground exploration development program. GMS is a leading mining and tunneling contractor with more than 40 years of experience serving underground mining operations across North America.

The planned underground exploration development program consists of approximately 800 linear meters of underground excavation and is currently anticipated to take approximately five months to complete. The work has been designed to provide strategic underground access for the next phase of approximately 12,000 meters of underground drilling. This work is expected to support the Company’s ongoing exploration and technical-study program, including work intended to inform a Feasibility Study at Lucky Shot assuming a Direct Shipping Ore approach targeted for H1 2027.
Initial priorities for the underground exploration development program include the West Drift extension to further explore the KM vein, where multiple hits of multi-ounce gold have been intersected and sampled (reference appropriate press release). The KM vein is at right angles to the Lucky Shot vein series and opens up another dimension to exploring the Lucky Shot mine area as well as the entire Willow district. After the West Drift extension is extended approximately 100 meters, underground development will start on the 2070 East Drift (see Figure 6). These workings are expected to facilitate new drill platforms for the next phase of underground drilling, which is currently expected to commence in mid-August 2026. Subsequent exploration development is expected to include extension of the Enserch Tunnel and development of the 2208 West and 2300 East drifts, subject to operational progress, contractor availability, permitting, technical priorities and ongoing exploration results.
