Cassiar Gold files tech report, updates drill campaign

Mr. Marco Roque reports CASSIAR GOLD PROVIDES 2025 EXPLORATION CAMPAIGN UPDATE & FILES NEW NI43-101 TECHNICAL REPORT ON THE CASSIAR GOLD PROPERTY Cassiar Gold Corp. has filed its independent National Instrument 43-101 technical report on its 100-per-cent-owned flagship Cassiar gold property located in Northern British Columbia, Canada, and has provided an update on the 2025 exploration activities. The NI 43-101 report, with an effective date of June 8, 2025, is titled "National Instrument 43-101 Technical Report on the Cassiar Gold Property," can be viewed on Cassiar Gold's website and has been filed under the company's profile on SEDAR+. The NI 43-101 report was authored by Scott Zelligan, PGeo, and Chantal Jolette, PGeo, both whom are independent qualified persons in accordance with National Instrument 43-101 and the companion Policy 43-101CP. The 2025 season's 7,000-metre drill campaign is in progress; expanded beyond its initial 5,000 m scope. 5,211 m of drilling has been completed at the Cassiar North project area to date, including: 2,080 m completed at the Taurus deposit; 3,131 m completed at the Newcoast target; drilling remains in progress. At the Newcoast target the company has drilled its deepest hole to date (720 m) with encouraging visual observations including evidence of widespread hydrothermal alteration. NI 43-101 report filing: The NI 43-101 report contains updated resources at a 0.4 g/t (gram per tonne) Au (gold) cut-off and $2,400 (U.S.)/ounce gold price comprise: Indicated mineral resource: 8.8 million tonnes (Mt) at 1.43 g/t Au for 410,000 ounces; with an additional; Inferred mineral resource: 63.2 Mt at 0.95 g/t Au for 1.93 million ounces. The updated mineral resource estimate extends from surface to a maximum pit depth of 307 m, with 91 per cent of the resource occurring within 150 m of surface. This resource holds strong potential for expansion in most directions with several areas of mineralization identified beyond the extent of the current pit shell model and sparse drill data between mineralized areas. "I am grateful for the tremendous efforts made by our technical team in completing this new pit-constrained NI 43-101-compliant technical report at the Taurus deposit," stated Marco Roque, president and chief executive officer of Cassiar Gold. "The new MRE outlines an expanded, robust, near-surface, pit-constrained asset with great access. We are now excited to complete our 7,000 m drill program across the Cassiar gold property that will include drilling at the Taurus deposit and Newcoast, which we believe to have a similar potential to Taurus." 2025 drill program overview The company's 2025 drill campaign commenced on June 20 and continues with drilling at the Newcoast target in the Cassiar North project area. The program is progressing ahead of schedule with an expanded scope and is projected to conclude in the fall. The program scope will consist of approximately 7,000 m over roughly 20 drill holes at the Cassiar North project area at both deposit-based and regional targets within the 59,000-hectare land package. To date during the 2025 season, 5,211 m have been completed over 15 drill holes. Cassiar North project area -- Taurus deposit To date a total of nine drill holes totalling 2,080 metres have been completed at the Taurus deposit in 2025. Drilling at Taurus consists of a series of stepout holes designed to expand the deposit laterally beyond the known mineralized footprint. Cassiar North project area -- Newcoast target A total of 3,131 m over six drill holes has been completed in 2025 at the Newcoast target, which is located south of the Taurus deposit near the Stewart-Cassiar Highway. The Newcoast prospect is host to numerous gold-bearing quartz veins and mineralized showings over four kilometres in east-west lateral extent which has been explored previously by limited fieldwork and sparse, widely spaced drilling, including nine holes completed during phase 1 and phase 2 drill programs in 2023 and 2024, respectively. The target area is situated along a 15 km northwest trend of past-producing gold deposits which include the Taurus deposit, prospects and past-producing high-grade veins across the property. The trend is associated with the development of gently dipping stacked shear zones between basal units that are host to mineralization. Drilling conducted at Newcoast in 2023 and 2024 encountered a broad series of sheeted quartz veins with extensive alteration and disseminated sulphide mineralization similar to the Taurus deposit in multiple drill holes, returning 141.4 m of 0.89 gram per tonne (g/t) gold (Au) from 143.1 m down hole (see news release Jan. 22, 2025). This season's drilling is designed to test continuity and expansion potential of mineralization encountered during the 2023 and 2024 drill campaigns and field programs (see news release April 16, 2025), as well as evaluate prospective chargeability anomalies identified in 2024 induced polarization survey results. Preliminary highlights from this season's Newcoast drilling completed to date includes an extensive network of alteration, quartz veining and sulphide mineralization encountered in infill drill hole 25NC-010 designed to test the continuity of mineralization within a 250 m wide gap in drill data from recent exploration campaigns. Another notable intercept -- encountered in drill hole 25NC-013 -- comprises a broad intercept of intermittent quartz veining and pyrite mineralization hosted in altered mafic volcanic rocks at greater depths than encountered in any previous drill hole at Newcoast, immediately overlying an argillite unit at depth. Style is similar to parts of the Taurus deposit. This interval of sulphide-mineralized quartz veining in basalt host, overlying deep water sediments, provides support for a regional interpretation of stratigraphic repetition attributable to thrust stacking across the Cassiar gold property. Elsewhere on the district-scale property, at higher elevations (in example, the past-producing Main mine at the Cassiar South project area), direct evidence of stacking of mafic volcanic panels known to host mineralized quartz veins, occurring between stacked shear zones localized along sedimentary and ultramafic units demonstrates the potential for gold-bearing quartz veins to occur at multiple levels within a broader package of mafic volcanic flows. Initial observations from Newcoast drill hole 25NC-013 highlight the potential for additional Taurus-style mineralization to occur within such extensive untested areas at different levels in the Cassiar North project area. Effective today Sept. 9, 2025, the company has awarded 350,000 restricted share units (RSUs) to certain advisers of the company pursuant to its fixed RSU/DSU (deferred share unit) plan (RSU/DSU plan). The RSUs will vest with two-thirds of the RSUs vesting in 12 months from the date of the grant, and the remaining one-third of the RSUs and DSUs vesting in 24 months from the date of grant. Each vested RSU will be satisfied for one full paid and non-assessable common share issued from treasury at a price based on the closing price of the common shares on Sept. 8, 2025. The stock option plan and the RSU/DSU plan provides for awards of no more than 14,665,930 common Shares. Qualified person Jill Maxwell, PGeo, Cassiar Gold's vice-president of exploration, who is a qualified person as defined by National Instrument 43-101 has verified and approved the technical information in this press release. About Cassiar Gold Corp. Cassiar Gold is a Canadian gold exploration company holding a 100-per-cent interest in its flagship Cassiar gold property located in British Columbia, Canada. The Cassiar gold property spans 590 square kilometres and consists of two main project areas: Cassiar North, which hosts an updated mineral resource estimate (MRE) for the Taurus deposit prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards incorporated by reference in NI 43-101. The pit-constrained MRE contains indicated mineral resources of 8.8 million tonnes (Mt) at 1.43 grams per tonne gold (g/t Au) for 410,000 ounces of gold in addition to inferred mineral resources of 63.2 Mt at 0.95 g/t Au for 1.93 million ounces (Moz) of gold using a 0.4 g/t Au cut-off grade; 91 per cent of ounces occur within 150 m of surface (see NI 43-101 Technical Report titled "National Instrument 43-101 Technical Report on the Cassiar Gold Property," prepared by Mr. Zelligan, PGeo, and Ms. Jolette, PGeo, and dated effective June 8, 2025); Cassiar South, which hosts numerous gold showings, historical workings and exploration prospects. Historical underground mines in the Cassiar South area have yielded over 315,000 oz of Au at average head grades of between 10 and 20 g/t Au (NI 43-101 technical report titled "National Instrument 43-101 Technical Report on the Cassiar Gold Property," prepared by Mr. Zelligan, PGeo, and Ms. Jolette, PGeo, and dated effective June 8, 2025), underscoring the high potential for further discovery and expansion of high-grade orogenic gold veins. The company also holds a 100-per-cent interest in properties covering most of the Sheep Creek gold camp located near Salmo, B.C., Canada. The Sheep Creek gold district ranks as the third-largest past-producing orogenic gold district in British Columbia with historical gold production of 742,000 ounces gold at an average grade of 14.7 g/t gold from 1900 to 1951. Minimal exploration work has been conducted since the 1950s. We seek Safe Harbor.
