TRIBECA RESOURCES PROVIDES UPDATE ON FIELD ACTIVITIES IN CHILE AND ENGAGES TORREY HILLS CAPITAL

Fieldwork is progressing at Tribeca Resources Corp.'s Jiguata porphyry copper exploration project. This is running in parallel with preparations to commence drilling on the Chirsposo Sur target at the La Higuera project.

Highlights:

• Predrilling exploration activities are partially completed at the Jiguata property, with data and results now pending.
• Preparations are being undertaken for phase 3 drilling at the cornerstone La Higuera IOCG (iron oxide copper-gold) project, following the signing of an access agreement over the Chirsposo Sur target area.
• San Diego Torrey Hills Capital Inc. (Torrey Hills) has been engaged to provide market awareness and investor relations services.
• Stock options have been granted to Global Ore Discovery Pty. Ltd., which is advising on exploration work at the Jiguata property, or to an entity controlled by the principals of Global Ore.

Tribeca Resources chief executive officer, Dr. Paul Gow commented: "We are very pleased with the rapid start to the extensive field program at the exciting Jiguata property. Information coming in from the geological mapping and preliminary satellite data interpretation confirms the presence of multiple large alteration systems, importantly with a variety of alteration assemblages commonly associated with high-sulphidation epithermal environments.

"In tandem, we are moving ahead rapidly with preparations for drill testing of the Chirsposo Sur target at the La Higuera IOCG project. We intend to commence drilling in March and are eager to see what the drill core yields in this compelling target that displays coincident anomalies in multiple geophysical data sets and sitting just below shallow gravel cover."

Jiguata porphyry copper-molybdenum property

The Jiguata property is a 10,000-hectare property located in the Tarapaca region in northern Chile. It is situated in the northern extension of the prolific Palaeocene and Eocene-Oligocene porphyry copper belts, where it is overprinted by the younger Miocene belt of magmatism that hosts recent large-scale, high-sulphidation epithermal gold and porphyry copper-gold discoveries farther to the south, including Vendaval copper-gold porphyry (First Quantum) and Salares Norte gold-silver high-sulphidation epithermal (Goldfields).

Geological mapping

Tribeca's first field program since signing the Jiguata property option agreement (on Oct. 28, 2025), commenced in December, 2025, and significant progress continues to be made. Geological mapping to date has been focused on the four large alteration systems identified from satellite imagery and historic mapping. Mineral assemblages commonly associated with high-sulphidation epithermal alteration are present, including broad zones of quartz-alunite alteration and localized vuggy silica zones. Lesser propylitic and phyllic alteration, which can be associated with deeper or more distal portions of porphyry high-sulphidation systems, has also been mapped within the most northwestern alteration system.

Preliminary mapping also indicates the presence of potential porphyry-related quartz-dominated veins, typically termed B-type or D-type veins in the central project area. Multiple hydrothermal breccias, commonly with the matrix replaced by quartz-alunite, have been mapped, as has at least one dacitic dome complex. Mapping is continuing, with a focus on providing more detail within the zones considered as prospective based on the initial mapping.

In general, the mapping appears to indicate that faults of northeast and northwest orientations are predominant. This accords with historic mapping and with the apparent regional control on the alteration zones delineated in the Worldview3 data.

Sampling

Rock and soil sampling has been continuing, with approximately 370 soil samples and 50 rock samples collected to date. The soil sampling to date has been focused within the exposed central alteration zone on 200-metre-by-200-metre or 200-metre-by-100-metre staggered grids. Laboratory results are awaited, but analysis undertaken on the samples by pXRF (portable X-ray fluorescence) provides a preliminary outline of elemental distribution, with data still being processed. The pXRF results are preliminary in nature and are used for screening purposes; laboratory results are pending and will be reported once received.

Worldview3 satellite data acquisition and processing

Approximately 100 square kilometres of Worldview 3 high-resolution multispectral satellite imagery was tasked and acquired in December, 2025, with cloud-free data received in early January, 2026. The resulting high-resolution imagery is being utilized by the mapping team for fact and interpretation maps. False-colour images produced have highlighted four alteration centres aligning along regional northwest and crosscutting northeast structures. Initial interpretation indicates that these centres are displaying advanced argillic to intermediate argillic alteration colouring with coincident areas of strong iron oxides (gossanous) and potentially jarosite, which are consistent with the upper parts of a high-sulphidation epithermal and the tops of porphyry deposits elsewhere in the Andes.

These satellite-derived alteration interpretations are preliminary in nature and require further field confirmation.

Ground magnetic surveying

The field collection component of a ground magnetic survey by Argali Geofisica Chile EIRL was completed on Jan. 19, 2026. Most of the project area was covered with 200-metre-spaced east-west lines. In general, the young, flat-lying volcanics are moderately magnetic, which produces significant near-surface noise. Where the overlying unit has been eroded or is not present, the magnetic intensity is significantly lower. Final products, including a 3-D inversion, are awaited. The results will be integrated with the geological mapping and other data to aid interpretation.

La Higuera IOCG project

The Chirsposo Sur target is one of five discrete targets on the La Higuera IOCG project. It comprises an interpreted strong hydrothermal magnetite alteration system under thin gravel cover in the southern project area. Inversion of the ground magnetic data indicates the system comprises a steeply dipping north-south-oriented magnetite alteration system of 1.2-kilometre strike length. The interpreted body is also coincident with an intense (greater than 30 millivolts per volt) north-south IP (induced polarization) chargeability trend that stretches over 2.4 kilometres, along with a broadly coincident 0.5-to-1.0-milligal residual gravity anomaly.

Two historic vertical diamond holes at the Chirsposo Sur target, drilled approximately 200 metres to the west of the body, intersected IOCG-style alteration with weak copper mineralization (eight metres at 0.23 per cent copper from 38 metres in hole CB-02), as reported in the National Instrument 43-101 technical report filed by Tribeca Resources on Oct. 24, 2022, and demonstrate strong magnetite alteration with a coarse-grained, pyrite-dominated sulphide assemblage.

For additional information, including comments on the relevance and reliability of the foregoing estimates and the key assumptions, parameters and methods used to prepare such estimates, please refer to the La Higuera technical report.

The planned drill program comprises three diamond holes for approximately 1,050 metres, with two holes to test discrete magnetic highs within the target and one hole to test a rare resistivity-low anomaly in the IP data.

Engagement of Torrey Hills

Further, Tribeca announces that it has engaged Torrey Hills, an investor relations firm based in Rancho Santa Fe, Calif., to provide market awareness and investor relations services to the company, subject to acceptance by the TSX Venture Exchange.
