- Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.
- The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.
- The Mineral Resources in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council.
- The Mineral Resource Estimate was prepared for a potential open pit scenario using a constrained pit shell (with 45-degree slopes) at a 0.7 g/t gold equivalent cut-off grade and an underground mining scenario using a 0.75 g/t gold equivalent cut-off grade. Cut-off grades were derived from US$ 1,850/oz gold, US$ 21/oz silver, US$ 3.75/lb copper, CAD:USD of 0.77, C$ 2.50/tonne open pit and C$8.50 underground mining cost, C$ 48.25/tonne milled processing costs for the Copper Belle, 300H, R66, DS5 and 300-N domains, and C$ 28.50/tonne milled processing costs for the CS-600 domain, and a C$ 1.50/tonne G&A cost. Process recoveries of 90% for gold, 80% for copper, and 80% for silver were used for the CS-600 domain and 90% for gold and 80% for silver with no copper for all other mineral domains
- AuEq g/t = Au g/t + (Ag g/t*0.01009) + (Cu ppm*0.0001236)
- A mineral estimate of the material within the defined pit that exists outside of the outlined mineral domains was completed and is included within the Inferred Mineral Resource.

Mineral Resource by Domain – Combined Pit and Underground
The Goldstorm Deposit consists of six mineral domains with unique geological characteristics. Five of the domains are gold-dominant with lesser proportions of silver and copper. Domain CS-600 is dominantly gold and copper rich, with lesser silver. The CS-600 hosts the majority of the copper at the Goldstorm Deposit and consists of a well-defined intrusive porphyry system. Table 6 summarizes the Indicated and Inferred Mineral Resources for each mineral domain.

The initial mineral resource estimate for the Goldstorm Deposit represents a very large structurally controlled gold-silver-copper porphyry mineralizing system that is open to further expansion with drilling. In addition to the Goldstorm Deposit, the Treaty Creek Property also includes many additional zones and showings of hydrothermal alteration and gold with or without base metals that have formed in porphyry and epithermal settings. The Eureka, Calm Before the Storm (CBS), and Perfectstorm zones are considered to be early-stage to advanced-stage exploration targets.
Future exploration will target the Goldstorm and Copper Belle Resource, in particular the limits of the 300 Horizon, the CS-600, and the DS-5 domains within the Goldstorm Deposit. Definition drilling within the current resource will target converting Inferred Mineral Resources to the Measured and Indicated Mineral Resource classifications where possible. Future exploration drilling programs will continue to define the Perfectstorm, Eureka and CBS zones. The overarching goal of future exploration programs is to increase the size of the current Treaty Creek Property mineral resource and to make new significant discoveries, as well as outline the economic potential of the Goldstorm Deposit.
The Treaty Creek Property has a long history of intermittent exploration dating back to the initial discovery of the Treaty Gossan in 1928 by prospectors Charles Knipple and Tim Williams. Consolidated Mining & Smelting Company of Canada Ltd. (Cominco) completed exploration activities on the Property from 1929-1931; however, these exploration results were not published, and the Property was subsequently abandoned. Occasional prospecting activity was undertaken by several exploration companies between 1953 and 1980, with no significant results reported. More complete records of exploration activity date back to 1980 when Ed Kruchkowski staked the Treaty Creek Property. In 1984, Teuton Resources acquired the claims and since then several option agreements have been executed with several mineralized zones being discovered.
The discovery of the Copper Belle Zone, which now exists as the southernmost domain in the Goldstorm Deposit, occurred in 2007 by American Creek Resources. In 2016, Tudor Gold commenced an option agreement to explore Treaty Creek. Exploration drilling to the north of Copper Belle lead to the delineation of the larger, Goldstorm Deposit. The Deposit consists of several unique, large, mineralized domains and currently remains open to further discovery.
In August of 2016, a magnetotelluric geophysical (“MT”) survey was completed in the Copper Belle area and extending to the northeast and southwest. In 2022 a Helicopter-Borne High Resolution Aeromagnetic VLF-EM Survey was completed. The survey targeted the Goldstorm Deposit as well as targets to the north and south. The purpose of the survey was to delineate major magnetic subsurface structures corresponding to monzonite and diorite intrusive stocks within the Goldstorm Deposit and surrounding areas.
Exploration success at the Goldstorm Deposit has been largely dependent on HQ/NQ sized diamond drilling. A total of 190,217 meters of drilling in 261 drill holes have been completed at Treaty Creek by Tudor Gold to date. A summary of drill production by year is provided in Table 1-1 seen below.
In 2016, three holes were drilled at the Copper Bell Zone. Highlights included CB-16-03 which was collared 550 meters northeast of the historic Copper Belle Zone and intersected 338 meters of 0.70 g/t Au from 88 meters.
In 2017 a more extensive drilling delineation program was employed. Several drill holes intersected long intervals of Gold, Silver and Copper mineralization up to depths of approximately 500 meters, using 50 meter step-out spacing where possible. In 2018 Tudor followed up on encouraging drill results to the northeast of Copper Belle, by concentrating in a zone that was newly named the Goldstorm Zone, formerly Copper Belle. A total of 12 drill holes were completed with increased drill spacing from 100 to 150 meters, and down hole depths as great as 700 meters. The northeastern most drillhole drilled at the end of the exploration season, CB-18-39, intercepted 563.8 meters of 0.98 g/t Au.
In 2019, Tudor Gold continued to expand the Goldstorm Zone with step-out drilling to the east and northeast (300 meters) based off the promising results returned from drill hole CB-18-39. Long continuous Gold mineralization was encountered, such as hole GS-19-42 that intercepted 0.68 g/t Au over 780 meters, including 1.27 g/t Au over 252 meters, and drill hole GS-19-52 that intercepted 1.00 g/t Au over 336 meters, including 2.01 g/t Au over 87 meters.
In 2020, extensive drilling allowed the delineation of three large, separate mineral domains; 300H, CS-600 and DS5. Drill hole GS-20-65 yielded 1.07 g/t Au over 930 meters from 34.5 meters in the 300H domain, including 348 meters of 2.04 g/t Au. The most north-eastern hole targeting the DS5 domain, GS-20-64, returned 550.5 meters of 0.90 g/t Au, including 154.5 meters of 1.39 g/t Au. Following the March 2021 Mineral Resource Estimate, extensive drilling campaigns in 2021 and 2022 significantly expanded the CS-600 domain as well as higher grade mineralization within DS5. Infill drilling was also performed at the 300H domain and two new domains, Route 66 and NS Stockwork (NS STK), were discovered. The CS-600 is an intrusive related porphyry that hosts the majority of the deposits Copper, along with substantial Gold grades and intercepts. Drill hole GS-21-113 returned an intercept of 405 meters of 0.65 g/t Au, and 0.62% Cu, and drill hole GS-22-159 returned 180 meters of 0.92 g/t Au and 0.61% Cu. Higher grade intervals have been encountered in further north and northeast step out drilling, such as drill hole GS-22-134, which returned a 25.5 meter long intercept of 9.66 g/t Au and 0.24% Cu, including 4.5 meters of 20.61 g/t Au and 0.20% Cu, starting from 1474.5 meters downhole.
In March 2023, an updated Mineral Resource Estimate was published increasing the Goldstorm deposits indicated Gold grade by 38% (from 0.66 g/t to 0.91 g/t), and total pounds of Copper by 98% (from 1.1 Blbs to 2.2 Blbs). These significant advancements are due to the success of the 2021 and 2022 drilling campaigns which delineated higher grade zones of the 300H domain and continued expanding the CS-600 and DS5 domains to the northeast and at depth. To date, the deposit remains open in all directions.

The Treaty Creek Property contains the Goldstorm Deposit and is hosted in Early Jurassic intrusions within surrounding Late Triassic and Early Jurassic volcano-sedimentary rocks that are part of the Stikine volcanic island-arc terrane. Arc magmatism across Stikinia and Quesnellia led to a multi-episodic, Late Triassic to Early Jurassic metallogenic event that generated porphyry intrusion-related mineral deposits, regionally. The Treaty Creek Property and Goldstorm Deposit are situated both spatially and temporally relative to the unconformable contact between Upper Triassic Stuhini Group and Jurassic Hazelton Group. The Hazelton Group consists primarily of andesitic to basaltic volcanics and volcaniclastic with a range of fine to coarse clastic sediments. In some cases, basal Hazelton units include granitoid-cobble conglomerate and interbedded quartz-rich arkose, derived from exhumed Triassic plutons. The lower Hazelton Group is a latest- Triassic to Toarcian arc-related andesitic sequence with local felsic centres. The associated Tatogga and Texas Creek Suite intrusions are key mineralizing agents for porphyry copper, gold, and volcanogenic massive sulphide (VMS) deposit formation in northwestern Stikinia.
In the Treaty Creek Property area, the Hazelton Group consists of the Jack, Betty Creek and Salmon River Formations. Jack Formation rocks consist of clast supported granitoid pebble and boulder conglomerate and are present along the west central part of the Property. Overlying the Jack Formation, farther to the east, the Betty Creek Formation is composed of the Unuk River and Treaty Ridge Members. At the toe of the Treaty Glacier, undifferentiated andesite and epiclastic rocks belong to the Unuk River Member.
Large hydrothermal alteration haloes are developed around the intrusive complexes in the Mitchell and Sulphurets Deposits areas. Similar alteration is present at the Treaty Creek Property and surround several of the mineral zones on the Property including the Goldstorm Deposit. Potassic alteration is closely associated with copper and gold mineralization in the Mitchell intrusions and adjacent Stuhini and Hazelton Group Rocks. The potassium alteration zones are overprinted by propylitic and chlorite-sericite alteration and surrounded by widely developed quartz-sericite pyrite (sericitic) alteration zones.
Major structural features in the Treaty Creek Property area are regional scale contractional faults along with associated local dilational faulting, formed within the Cretaceous Skeena Fold Belt. The west side of the Treaty Creek Property area lies primarily on the upper block of the Sulphurets Thrust Fault. The Sulphurets Thrust is an east-vergent thrust fault formed during Cretaceous transpression and is the immediate hanging wall to the porphyry deposits at Seabridge’s KSM Property. This structure extends to the northeast of the Sulphurets district onto the Treaty Creek Property and along with the interaction of other local thrust faulting, is considered to be a control on formation of the porphyry-style gold mineralization. Local to the Goldstorm Deposit, compressional deformation is taken up by regional thrust faulting named Treaty Thrust Fault 1 (TTF1) and Treaty Thust Fault 2 (TTF2). These local to regional scale thrust faults represent the hangingwall (TTF1) and footwall (TTF2) contacts of the deposit. The Goldstorm mineralized system is comprised of six distinct mineralized domains including Copper Belle, 300H, CS-600, Deep Stockwork 5 (DS5), Route 66 (R66), and North-South Stockwork (NS STK). The Copper Belle domain exists at the southwest end of the Goldstorm Deposit and represents a gold-dominant, shear hosted mineralized system. The 300H, CS-600, and DS5 domains comprising the Goldstorm mineral system are tabular bodies dipping 45 to 50 degrees to the northwest. The near surface 300H domain hosts pervasively disseminated auriferous-pyrite and fine gold-bearing pyrite veinlets and stringers. The CS-600 domain underlies the 300H domain and gold-copper dominant mineralization is associated with quartz veinlet stockworks, hydrothermal breccias, and porphyritic diorite intrusive stocks. Beneath the 300H and CS-600 domains are the DS5 domain which is a gold-dominant quartz-pyrite veinlet stockwork zone that carries minor silver values. Additionally, the R66 and NS STK domains represent narrow 20 – 50 m corridors of north south striking, high-grade gold dominant, quartz stockwork mineralization.
