Tribeca Resources Provides Update on Activities Across its Expanded Chilean Copper Exploration Portfolio

The most recent news release from Tribeca Resources Corporation (TRBC) on December 15, 2025, provides an update on its exploration activities across its Chilean copper portfolio. Key points include: - Jiguata Property: Fieldwork has commenced on the Jiguata porphyry copper-molybdenum property in the Tarapacá region of northern Chile. This work includes mapping, surface sampling, and planned geophysical surveys. The CEO, Dr. Paul Gow, expressed optimism that this work will lead to "compelling drill targets" for testing later in 2026. This follows the signing of a definitive purchase option agreement for Jiguata in late October. - La Higuera IOCG Project: A Phase 3 drill program is planned for the Chirsposo Sur Target at the La Higuera IOCG Project in the Coquimbo Region in Q1 2026. This target has not been previously drilled by Tribeca and is noted for its geophysical similarities to the company's Gaby IOCG discovery, located four kilometers to the north. The objective is to find similar breccia-hosted copper-gold mineralization. - The release references historic drilling results from Gaby (268m at 0.66% Cu, 0.14 g/t Au) and Chirsposo (167m at 0.21% Cu, 0.06 g/t Au) targets within the La Higuera project.

This news is a routine positive update. It confirms the company's progress in executing its exploration strategy, particularly following the successful C$6.5 million private placement closed on October 23, 2025, and the definitive option agreement for the Jiguata property signed on October 29, 2025. - Positive: The commencement of fieldwork at Jiguata demonstrates tangible progress on a newly acquired, large-scale porphyry target. The planned Phase 3 drill program at La Higuera's Chirsposo Sur target in Q1 2026 is a significant step, as this is a new, undrilled target for Tribeca with favorable geophysical signatures. It indicates that the company is actively deploying its recently raised capital for exploration. - Neutral: The news does not contain new assay results or a discovery. It is an operational update that reiterates previously communicated intentions and timelines, especially concerning the Jiguata property. The market may have already factored in these planned activities following the financing and option agreement news. - Negative: No negative impacts are discernible from this news release.

Overall, the news reinforces the company's commitment to advancing its projects and provides clear upcoming milestones. While not a game-changer, it is an essential piece of information for investors monitoring the company's progress and the efficient use of its raised capital.

• Flagship Project(s):
  • La Higuera IOCG Project (Coquimbo Region, Chile): This is described as the company's cornerstone asset. Previous drilling has led to the Gaby IOCG discovery. The company plans a Phase 3 drill program at the Chirsposo Sur Target in Q1 2026, which is an undrilled target for Tribeca, presenting potential for new discoveries. The property is subject to a 1% Net Smelter Return (NSR) royalty on the Caballo Blanco concessions and a 1% NSR on the Benja and Blanco concessions.
  • Jiguata Porphyry Copper-Molybdenum Property (Tarapacá, Chile): Tribeca recently secured a 5-year option to acquire a 100% interest in this 10,000-hectare property (October 2025). It is strategically located 120 km north of major copper mines like Collahuasi and Quebrada Blanca. The company has commenced fieldwork (mapping, sampling, geophysics) with an aim to define drill targets for late 2026. This property is subject to a 2.0% NSR royalty, with an option to repurchase 100% of the royalty for US$20 million.
  • Chiricuto Property (Atacama Region, Chile): A 570-hectare property in the Mantoverde district. The company completed a maiden 1,586-meter drill program in May 2025, intersecting porphyry-style mineralization with encouraging gold values. Evaluation of all drill results is ongoing to determine the next steps. This property is subject to a 0.5% NSR royalty retained by the vendors.
