About Titanium
Titanium (Ti) is as strong as steel, but much less dense. It is therefore important as an alloying agent with many metals, including aluminum, molybdenum and iron. These alloys are mainly used in aircraft and spacecraft because of their low density and ability to withstand extreme temperatures. They are also used in sports equipment, laptops, bicycles and medical prostheses. Recently, this metal has been used in some battery components.

Sun Summit Minerals Corp. (TSXV: SMN) (OTCQB: SMREF) (“Sun Summit” or the “Company”) is pleased to report the results of its inaugural Mineral Resource Estimate (“MRE”) for the Company’s 100% owned Buck Project in central British Columbia.

Highlights:

• Indicated Mineral Resources at Buck Main are estimated to include 19,100 gold equivalent ounces1 (oz AuEq) (18,300 oz gold and 158,000 oz silver) at a grade of 0.519 g/t gold equivalent1 (g/t AuEq) (0.496 g/t Au, 4.3 g/t Ag) contained within 1.15 million tonnes (Mt).
• Inferred Mineral Resources at Buck Main are estimated to include 820,400 oz AuEq1 (775,500 oz gold and 8,435,000 oz silver) at a grade of 0.489 g/t AuEq1 (0.462 g/t Au, 5.0 g/t Ag) contained within 52.2 Mt.
• The near-surface Mineral Resource at Buck Main is constrained within an optimized open-pit shell using a 0.25 g/t AuEq cutoff, ensuring reasonable prospects for economic extraction.
• Additional upside at Buck Main as the deposit remains open for expansion in most directions and at depth.
• Effective discovery with average drill costs of CAD $18 per ounce of AuEq included in the MRE.

Notes:
1. Gold Equivalent (AuEq) grade is based on AuEq = Au + 0.0053*Ag (see notes to Table 1 below)

Niel Marotta, Sun Summit CEO commented: “This initial resource is a major milestone for Sun Summit and demonstrates the significant gold-silver potential of the Buck Main deposit. Sound and aggressive infill drilling programs over the past three seasons have successfully achieved our goal of demonstrating the continuity of the resource in the central, high-grade area of the deposit. The deposit remains largely open at depth and along strike and future drilling will examine these areas for further expansion. The scale, grade, and potential economic viability of the Buck Main deposit provides a strong foundation for further expansion and reinforces the Company’s strategy of advancing this district-scale gold-silver asset in British Columbia.”

Buck Main Mineral Resource Estimate

Table 1. Summary of Indicated and Inferred Mineral Resources for the Buck Main deposit

Notes to the 2025 Resource Table:

1. Resources are reported using the 2014 CIM Definition Standards and were estimated using the 2019 CIM Best Practices Guidelines, as required National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”)
2. The base case Mineral Resource has been confined by “reasonable prospects of eventual economic extraction” shape using the following assumptions:

• Metal prices of US$2250/oz Gold, US$26/oz Silver
• Metallurgical recovery of 79% Gold and 38% Silver
• Payable metal of 95% Silver, 99% Gold in dore
• Forex of 0.72 $US:$CDN
• Offsite costs (transport, smelter treatment and refining) of CDN$8.50/oz Gold and CDN$0.25/oz Silver.
• Processing Costs of CDN$12/tonne milled and General & Administrative (G&A) costs of CDN$ 2.50/ tonne milled
• Mining cost of CDN$2.56 / tonne for mineralized material and CDN$2.50/tonne for waste
• 45-degree pit slopes
• The 120% price case pit shell is used for the confining shape

1. The resulting net smelter return (NSR) for the purpose of the AuEq calculation = Au*CDN$98.60/g*79% recovery rate + Ag*CDN$1.08/g*38% recovery rate
2. The resulting AuEq = Au + 0.0053*Ag
3. Numbers may not add due to rounding
4. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the estimated mineral resources will be converted into mineral reserves.

The Mineral Resources for the Buck Main deposit has been estimated using a 0.25 g/t AuEq cutoff determined using assumptions listed in the footnotes of Table 1. These assumptions satisfy the requirements of reasonable prospects for eventual economic extraction. Table 2 shows cutoff sensitivities at different grades.

The Buck MRE is centered on the Buck Main deposit, 12 km south of Houston, BC. The road accessible deposit comprises a broad, 800 metre striking zone of intermediate-sulfidation epithermal-related gold-silver mineralization hosted in intermediate to felsic volcanics and intrusions. The MRE is based on 42,440 metres of drilling in 161 holes, of which 34,386 metres in 98 holes were completed by Sun Summit between 2020 and 2023 (Figure 1, Figure 2, Table 3).

The effective date of the MRE, completed by Moose Mountain Technical Services is January 28, 2025. The Company will file a National Instrument 43-101 (NI 43-101) technical report on SEDAR+ within the mandated 45-day period following the date of this press release.

Gold and silver mineral resources were estimated as follows:

• Wireframing of overburden and mineralized domains based on geology.
• Assay capping based on Cumulative Probability Plots (CPPs).
• Compositing of assays to 3m lengths based on the domains.
• Variography to determine the anisotropy of the Au and Ag within each domain.
• Block model interpolations by inverse distance cubed (ID3).
• Classification of the resource to Indicated and Inferred based on the variography.
• Creation of confining pit shape based on industry standard prices and comparable costs.

Discovery Metrics

Sun Summit has efficiently delineated the Buck Main deposit with a total drilling cost of approximately CAD$18 per AuEq ounce included in the MRE. Since 2020, the Company has completed 98 drill holes at Buck Main, totaling over 36,400 meters. The MRE was informed by assay results from 123 drillholes and 27,034 metres of assayed intervals. The Company incurred CAD $15 million in drilling expenditures since 2020.

The low discovery cost reflects the efficiency of Sun Summit’s exploration strategy, which included systematic targeting using advanced geological modeling, geophysical surveys, and geochemical analysis. This exploration success underscores the strong potential for further resource growth, as the deposit remains open in multiple directions.

Next Steps

• Additional metallurgical testing will be initiated to optimize metal recoveries and evaluate potential byproduct elements, ensuring the economic viability of future mining operations.
• Further drilling designed to investigate the extents of the Buck Main deposit is recommended. Areas open to the north, west, and east will be targeted in future drill programs.
