Tribeca Resources Provides Update on Field Activities in Chile and Engages Torrey Hills Capital

(TheNewswire)

12 FEBRUARY, 2026 |VANCOUVER, BC – TheNewswire- Tribeca ResourcesCorporation (TSXV: TRBC) (OTCQB: TRRCF)(“TribecaResources”, the “Company”) ispleased to report that fieldwork is progressing at the Jiguataporphyry copper exploration project (the “Jiguata Property”). Thisis running in parallel with preparations to commence drilling on theChirsposo Sur target (the “Chirsposo Sur Target”) at the LaHiguera project (the “La Higuera IOCG Project”).

Highlights:

• Pre-drilling exploration activities are partiallycompleted at the Jiguata Property, with data and results now pending 

• Preparations are being undertaken for Phase 3 drillingat the cornerstone La Higuera IOCG Project, following the signing ofan access agreement over the Chirsposo Sur Target area 

• Torrey Hills Capital has been engaged to provide marketawareness and investor relations services  

• Stock options granted to Global Ore Discovery Pty Ltd(“GlobalOre”), which is advising on exploration work at theJiguata Property, or to an entity controlled by the principals ofGlobalOre 

Tribeca Resources CEO, Dr. Paul Gowcommented:

“We are very pleased with therapid start to the extensive field program at the exciting JiguataProperty. Information coming in from the geological mapping andpreliminary satellite data interpretation confirms the presence ofmultiple large alteration systems, importantly with a variety ofalteration assemblages commonly associated with high sulphidationepithermal environments.”

“In tandem we are moving aheadrapidly with preparations for drill testing of the Chirsposo SurTarget at the La Higuera IOCGProject. We intend tocommence drilling in March, and are eager to see what the drill coreyields in this compelling target that displays coincident anomalies inmultiple geophysical datasets and sitting just below shallow gravelcover.”

Jiguata Porphyry Copper-MolybdenumProperty

The Jiguata Property is a 10,000 hectare propertylocated in the Tarapacá region in northern Chile. It is situated inthe northern extension of the prolific Palaeocene and Eocene-Oligoceneporphyry copper belts where it is overprinted by the younger MioceneBelt of magmatism that hosts recent large scale high sulphidationepithermal gold and porphyry copper-gold discoveries further to thesouth, including Vendaval Cu-Au Porphyry (First Quantum) and SalaresNorte Au-Ag High Sulphidation Epithermal (Goldfields) (Figure1).

Geological Mapping

Tribeca’s first field program since signing theJiguata Property option agreement (on 28 October, 2025), commenced inDecember 2025 and significant progress continues to be made.Geological mapping to date has been focused on the four largealteration systems identified from satellite imagery and historicmapping (Figure 2).  Mineral assemblages commonly associated withhigh sulphidation epithermal alteration are present, including broadzones of quartz-alunite alteration and localized vuggy silica zones.Lesser propylitic and phyllic alteration, which can be associated withdeeper 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 ofpotential porphyry-related quartz-dominated veins, typically termed‘B’ or ‘D’-type veins in the central project area. Multiplehydrothermal breccias, commonly with the matrix replaced byquartz-alunite have been mapped, as has at least one dacitic domecomplex. Mapping is ongoing, with a focus on providing more detailwithin the zones considered as prospective based on the initialmapping.

In general, the mapping appears to indicate that faultsof northeast and northwest orientations are predominant. This accordswith historic mapping and with the apparent regional control on thealteration zones delineated in the Worldview3 data (Figure 3).

Sampling

Rock and soil sampling has been ongoing, withapproximately 370 soil (Figure 2) and 50 rock samples collected todate. The soil sampling to date has been focused within the exposedcentral alteration zone on 200m x 200m or 200m x 100m staggered grids.Laboratory results are awaited, but analysis undertaken on the samplesvia pXRF provides a preliminary outline of elemental distribution,with data still being processed. The pXRFresults are preliminary in nature and are used for screening purposes;laboratory results are pending and will be reported once received.

Worldview3 satellite dataacquisition and processing

Approximately 100 square kms of Worldview 3 highresolution multispectral satellite imagery was tasked and acquired inDecember 2025 with cloud free data received in early January 2026. Theresulting high-resolution imagery is being utilised by the mappingteam for fact and interpretation maps. False colour images producedhave highlighted four alteration centres aligning along regional NWand crosscutting NE structures. Initial interpretation indicates thatthese centres are displaying advanced argillic to intermediateargillic alteration colouring with coincident areas of strong ironoxides (gossanous), and potentially jarosite, which are consistentwith the upper parts of a high sulphidation epithermal and the tops ofporphyry deposits elsewhere in the Andes.These satellite?derived alterationinterpretations are preliminary in nature and require further fieldconfirmation.

Ground Magnetic Surveying

The field collection component of a ground magneticsurvey by Argali Geofísica Chile E.I.R.L was completed on 19 January2026. Most of the project area was covered with 200m-spaced east-westlines. In general, the young flat lying volcanics are moderatelymagnetic, which produces significant near surface noise. Where theoverlying unit has been eroded or is not present the magneticintensity is significantly lower. Final products, including a 3Dinversion, are awaited. The results will be integrated with thegeological mapping and other data to aid interpretation.

La Higuera IOCG Project

The Chirsposo Sur Target is one of five discretetargets on the La Higuera IOCG Project. It comprises an interpretedstrong hydrothermal magnetite alteration system under thin gravelcover in the southern project area. Inversion of the ground magneticdata indicates the system comprises a steeply-dipping north-southoriented magnetite alteration system of 1.2 km strike length. Theinterpreted body is also coincident with an intense (>30 mV/V)north-south IP chargeability trend that stretches over 2.4km, alongwith a broadly coincident 0.5-1.0 mGal residual gravityanomaly.

Two historic vertical diamond holes at the ChirsposoSur Target, drilled approximately 200m to the west of the bodyintersected IOCG-style alteration with weak copper mineralisation (8m@ 0.23% Cu from 38m in hole CB-02), as reported in the NI 43-101technical report filed by Tribeca Resources on October 24, 2022 (the“La Higuera Technical Report”), and demonstrate strong magnetitealteration with a coarse-grained pyrite-dominated sulphide assemblage.For additional information, including commentson the relevance and reliability of the foregoing estimates and thekey assumptions, parameters and methods used to prepare suchestimates, please refer to the La Higuera Technical Report.

The planned drill program comprises three diamond holesfor approximately 1,050m, with two holes to test discrete magnetichighs within the target, and one hole to test a rare resistivity lowanomaly in the IP data.
