Thunderbird Strengthens Argo Project with Promising Exploration Targets

Thunderbird Minerals Corp. (“Thunderbird” or the “Company”) has revealed a 39% increase in its land holdings at the Argo Copper-Gold Project (the “Project”). The Argo Property now covers 10,147.42 hectares (ha), incorporating additional areas with prospective for epithermal and porphyry-style copper-gold mineralization, including the historic York mineral occurrence.

Highlights from the York Mineral Occurrence

• The York mineral occurrence is situated at the junction of interpreted fault structures, which likely enabled the movement of hydrothermal fluids linked to regional magmatic activity.
• Historical exploration at the site has involved rock, soil, and stream geochemical sampling, trenching, airborne magnetic geophysical surveys, and drilling, with a primary focus on gold mineralization.
• Previous sampling identified a NW-SE trending geochemical anomaly for gold (Au), copper (Cu), and molybdenum (Mo), which aligns with several magnetic geophysical anomalies. Soil assays returned values up to 194 ppb Au, and rock samples from outcrops assayed up to 2.55 g/t Au.
• Trenching revealed a variety of rock types, including gneisses, schists, hornfelsed zones, and graphitic sediments of the Nicola Group, intruded by biotite granodiorite and monzonite. Some contacts display skarn alteration, and shear zones, reaching up to 18 m in width, exhibit limonitic alteration and contain anomalous levels of Au, Cu, As, Ag, and Sb.
• Historical drilling programs included shallow reverse-circulation/percussion drilling in 1982 (457.2 m across 7 holes) and 1988 (919 m across 10 holes), as well as a diamond drilling program in 1983 (809.07 m across 13 holes). All drill holes encountered anomalous gold values, including 5.7 g/t Au over 0.3 m, 2.8 g/t Au over 5.1 m, and 1.18 g/t Au over 10.15 m. Drilling also returned a 71.32 m intercept with 164 ppm Cu and 200 ppm Mo, indicating the potential for both epithermal gold and porphyry-style Cu-Mo mineralization.
• Gold mineralization is primarily found in arsenopyrite-bearing quartz veins and shear zones containing calcite and quartz veins, which may have overprinted an earlier porphyry system. Metasomatic minerals such as pyrite, chalcopyrite, sphalerite, and molybdenite are present at the granodiorite-hornfels contacts.
• The York target displays geological, geochemical, and geophysical anomalies that resemble those found in other alkalic copper-gold porphyry and intrusion-related gold systems (IRGS) within the Quesnel Trough. Notable deposits in the region include Taseko’s Gibraltar Mine, situated approximately 90 km to the southeast. The Gibraltar Mine is Canada’s second-largest copper mine, with reserves of 1.1 billion tons at 0.25% Cu and 0.007% Mo.

The 100% owned Argo Project is situated about 20 km northwest of Quesnel, British Columbia, Canada. The project is strategically located near key transportation and utility corridors, including Highway 97 and nearby electric transmission lines. The Argo Project lies within the Quesnel Trough, a region known for hosting some of British Columbia’s most productive copper mines, such as Copper Mountain, Gibraltar, Mount Polley, and Highland Valley.

The expansion of our Argo Copper-Gold Project further enhances our strategic position within the prolific Quesnel Trough, a region known for hosting some of British Columbia’s most productive copper mines. The additional claims not only increase our footprint by nearly 40%, but they also encompass prospective ground with potential for significant epithermal and porphyry-style mineralization.

John Newell adds, “This new territory provides exciting exploration upside as we advance the Argo Project. The favorable geological setting, historical work, and strategic location close to infrastructure underscore the Project’s potential to be developed into a significant copper-gold asset within Thunderbird’s growing portfolio.”
