Cassiar Gold Corp. (TSX-V: GLDC) (OTCQX: CGLCF) is pleased to announce results from the final 5,243 meters over eleven diamond drill holes of the 2025 exploration program at the Cassiar Gold project, located in northern British Columbia. The 2025 drill program comprised 7,308 m over 20 drill holes and concluded in early October, for which nine drill holes were previously reported. Results reported here identified a new higher grade, visible gold-bearing structure, and significantly extended known mineralization at the Newcoast prospect. These drill holes demonstrate potential for ongoing expansion of mineralization along key structural trends and identification of new mineralized areas with visible gold-bearing veins within extensive untested areas at the Cassiar Gold property.

Highlights:

Drill holes reported here are from the Newcoast Prospect, which is located 2 kilometers southeast of the Taurus deposit (Figure 1). All drill holes at Newcoast encountered broad intercepts of mineralization above 0.4 grams per tonnes gold in 2025 and successfully expanded an extensive, sparsely tested mineralized zone initially encountered during the 2023 drill program. A higher-grade intercept with visible gold was encountered in a newly identified mineralized structure while targeting discrete, previously untested chargeability anomalies along the Newcoast target corridor.

Drilling intercepts represent apparent widths of mineralized zones. A full summary of the latest results can be found in Table 1, and include:

• Drill hole 25NC-017 identified an area of new quartz veining with visible gold, returning:
  • 15.7 m of 3.80 g/t Au from 249.1 m downhole, including:
    • 176.50 g/t Au over 0.3 m 
• Drill hole 25NC-019:
  • 22.5 m of 3.52 g/t Au from 420.9 m downhole, including:
    • 42.41 g/t Au over 1.6 m, with
    • 51.68 g/t Au over 1.2 m 
• Drill hole 25NC-010:
  • 89.2 m of 0.71 g/t Au from 217.3 m downhole, including
    • 43.5 m of 1.12 g/t Au with 0.4 m of 5.59 g/t Au 
• Drill hole 25NC-013:
  • 167.5 m of 0.42 g/t Au from 499.4 m downhole

“We are pleased with the final results of the 2025 drill program. Intercepts at Newcoast further validate our belief that the Cassiar Gold property continues to offer considerable untapped regional potential,” stated Marco Roque, President and Chief Executive Officer of Cassiar Gold. “From a business perspective, as we continue to advance our priority exploration targets, we are looking forward to broadening our focus in 2026 to highlight our project’s unique advantages amid record gold prices, including established infrastructure and valuable optionality from past-producing high-grade mines.”

Cassiar North project area – Newcoast prospect

The Newcoast prospect is located roughly 2 kilometers southeast of the Taurus Deposit near the Stewart-Cassiar Highway (Figure1). Newcoast is host to numerous gold-bearing quartz veins and mineralized showings over 4 km in east-west lateral extent which has previously been subject to limited field work and sparse, widely spaced drilling, including nine holes completed during recent drill programs.

The drilling results reported in this news release are from eleven drill holes totaling 5,243 m (Figure 1,4) which tested the ongoing expansion potential and continuity of an extensive network of alteration, quartz veining and sulphide mineralization identified and extended in previous programs (see NEWS RELEASE, January 22, 2025), as well as evaluated new prospective chargeability anomalies recently identified in 2024 induced polarization survey results (see NEWS RELEASE, May 22, 2025).

Newcoast East: drill holes 25NC-017, -018, -016

Drill holes 25NC-017 and 25NC-018 (north-oriented), aimed to evaluate a previously untested area coincident with a series of discrete, parallel, linear chargeability highs along strike to the east of mineralized veining encountered in outcrop during the 2024 season, which yielded grab samples up to 25.60 g/t Au (see NEWS RELEASE, April 16, 2025). Drill hole 25NC-016 (south-oriented) was designed to undercut a historical drill hole 85 m to the south.

This set of holes identified a new series of quartz veins with visible gold and mineralized alteration halo, highlighting an ongoing potential for additional discovery along northeast trending lineaments in the Newcoast target corridor. Results include (Table 1; Figures 2,3,4):

• Drill hole 25NC-017 encountered multiple specks of visible gold, returning:
  • 176.50 g/t Au over 0.3 m, within 15.7 m of 3.80 g/t Au from 249.1 m downhole

• 17.20 g/t Au over 0.3 m, within 5.1 m of 1.36 g/t Au from 112.7 m downhole in hole 25NC-018

Drill holes 25NC-019, -010, -020

Drill hole 25NC-019 (southwest-oriented) was designed to test the potential for new near-surface mineralization northeast of the broader mineralized corridor, as well as infill within a 250 m gap in previous drilling. Drill holes 25NC-010 and 25NC-020 (northeast/north-oriented) served to reduce drill hole spacing within the same gap to within 50-100 m.

Mineralization was encountered along the interpreted continuation of prospective trends within the 250 m gap between Phase 1 and 2 series drill holes at Newcoast. Results include (Table 1; Figure 4,5,6):

• Multiple intercepts returned in hole 25NC-019:
  • 22.1 m of 1.52 g/t Au from 377.1 m downhole, including
    • 0.5 m of 36.00 g/t Au;
  • 22.5 m of 3.52 g/t Au from 420.9 m downhole, including
    • 42.41 g/t Au over 1.6 m, with 51.68 g/t Au over 1.2 m 
• 89.2 m of 0.71 g/t Au from 217.3 m downhole, including 43.5 m of 1.12 g/t Au in hole 25NC-010

Newcoast – expansion: drill holes 25NC-011 through 25NC-015

Drill holes 25NC-013 (northeast-oriented), 25NC-014 and 25NC-015 (southwest and south-oriented, respectively) were designed to step out to the northwest toward the Taurus deposit, as well as below the known extent of the mineralization, and at relatively shallow depth to the northeast.

All of these drill holes returned gold-mineralized intercepts, including 25NC-013 which encountered a broad intercept of intermittent quartz veining and pyrite mineralization, hosted in altered mafic volcanic rocks at greater depths than encountered in any previous drilling at Newcoast. Results include (Table 1; Figure 4):

• Drill hole 25NC-013:
  • 73.4 m of 0.45 g/t Au from 309.3 m downhole, including 0.4 m of 34.10 g/t Au, 0.4 m of 6.36 g/t Au, and 0.4 m of 5.12 g/t Au
  • 167.5 m of 0.42 g/t Au from 499.4 m downhole

Summary

Drilling at the Newcoast prospect continues to demonstrate clear potential for ongoing expansion of broad intervals of mineralization. These have strong similarities to the Taurus deposit and reinforce the prospectivity of the underexplored greater land package at the Cassiar Gold District. As we look forward to the upcoming field season, the technical team is actively integrating 2025 program outcomes into program planning to guide 2026 exploration efforts, including field-based investigations and drill targeting as we concurrently expand our focus to include assessment of additional opportunities inherent to the project.

Corporate Update

Metallurgical work for the Taurus deposit, which hosts the property’s foundational mineral resource estimate, is currently underway and results remain pending. Concurrent to, and in support of, planning 2026 exploration programming the Company is preparing to initiate an assessment of unmined higher-grade mineralization associated with past-producing small-scale vein systems at the Cassiar South project area, which could potentially be processed at the existing on-site permitted milling facility. Historical underground mines in the Cassiar South area have yielded approximately 315,000 ounces of gold at average head grades of between 10 and 20 grams per tonne ^[1]. In addition, the Company plans to undertake an evaluation of previous testing programs at a historical tailings management facility at Cassiar South. The evaluation will support further metallurgical testing to establish gold recovery.

Table 1. Significant 2025 drilling results from the Newcoast prospect based on a >0.4 g/t Au cutoff. While true thickness has not been established, drill holes are designed to cross at high to moderate angles within known corridors of mineralization based on orientations of mineralized areas defined by previous drilling and structural data from oriented drill core and outcropping veins.
