Tribeca Resources Signs Definitive Option Agreement to Acquire the Jiguata Porphyry Copper Property in Northern Chile

Tribeca Resources Corporation (TSXV: TRBC) (OTCQB: TRRCF) (“Tribeca Resources” or the “Company”) is pleased to announce that, further to the Company's news release dated June 19, 2025, it has entered into a definitive option agreement dated October 28, 2025 (“Option Agreement”) with private arm’s length vendors (the “Project Vendors”) to acquire a 100% interest in the 10,000 hectare Jiguata Porphyry Copper property (the “Jiguata Property”) over a period of 5 years (the “Purchase Option”).

The Jiguata Property, located in northern Chile, 120km north of the major mining company controlled Collahuasi and Quebrada Blanca mines (Figure 1), will be progressed in parallel with the Company’s two existing projects: La Higuera (the “La Higuera Property”) and Chiricuto (the “Chiricuto Property”), both located in the Chilean Coastal IOCG Belt.

Highlights:

Large epithermal and interpreted porphyry alteration system in the northern extension of the prolific Chilean porphyry-bearing Eocene-Oligocene Belt, with partial overprint and cover by younger Miocene age rocks
Drive-up access via paved Collahuasi road, nearby accommodation and associated infrastructure
Soil sampling, historic drilling, geological mapping and geophysics highlight a large 5km x 3km exploration target zone, with two existing discrete near drill-ready targets
Under the Option Agreement, during the first two years, Tribeca will make staged cash payments totalling US$ 100,000 and undertake a minimum of 3,000 meters of drilling
Pre-drilling activities at the Jiguata Property will be undertaken in parallel with further drilling at the Company’s flagship La Higuera Property

Tribeca Resources CEO, Dr. Paul Gow commented:

“We are very pleased to have now signed the definitive Option Agreement for this exciting porphyry copper exploration opportunity at Jiguata. Following the successful financing last week, preparations now are underway to commence fieldwork at Jiguata in the coming weeks.”

“The next twelve months will be a period of high activity for Tribeca, with drilling planned at our cornerstone La Higuera Property as well as at the Jiguata Property. Our now expanded portfolio of three high potential Chilean copper projects positions Tribeca Resources to capitalise on growing interest in quality copper exploration.”

The Jiguata Property option agreement

Tribeca has entered into a 5-year Option Agreement, giving it the right, but not the obligation, to acquire a 100% interest in the Jiguata Property. Tribeca has made a payment to the vendors of US$25,000 in connection with signing of the definitive Option Agreement, and will reimburse the Project Vendors approximately US$44,000 for the 2025 licence fee already paid by them. Under the terms of the Option Agreement, the total consideration and required work commitments, as applicable, will be as follows on a yearly basis:

1) If the Purchase Option is maintained 2) If the Purchase Option is exercised

Upon exercise of the Purchase Option (which remains at the sole discretion of the Company), the Project Vendors will retain a 2.0% net smelter return royalty (the “NSR Royalty”) over the Jiguata Property. Tribeca will have a right to repurchase 100% of the NSR royalty for US$20 million.

For more information regarding the terms of the Option Agreement, please see the Company’s press release dated June 19, 2025.

The Jiguata Property (see Figure 1 below) comprises 34 exploration concessions covering 10,000 hectares and is located in the northern extension of the Eocene-Oligocene metallogenic belt of northern Chile (Figure 1), where it has been overprinted by the Miocene magmatic belt. The prolific Eocene-Oligocene Belt hosts the giant Collahuasi, Chuquicamata and Escondida deposits.

Tribeca Resources plans to extend the historic mapping and surface sampling and undertake additional geophysics prior to proceeding with drilling at the Jiguata Property. Tribeca Resources will be the operator of the project.

Tribeca Resources Closes Upsized C$6.5 Million Non-Brokered Private Placement Offering

Tribeca Resources Corporation (TSXV: TRBC) (OTCQB: TRRCF) (“Tribeca Resources” or the “Company”) is pleased to announce that it has closed its previously announced non-brokered private placement offering of units of the Company (“Units”), pursuant to which the Company issued 30,903,183 Units at a price of $0.21 per Unit for aggregate gross proceeds of $6,489,668.43 (the “Offering”).

Tribeca Resources CEO, Dr. Paul Gow commented:

"The overwhelming and global interest, which led to a significant oversubscription of this Offering, is a strong validation of our growth strategy and the exceptional potential of our growing portfolio of Chilean copper exploration assets. As well as strong support from our current shareholder base, we are extremely pleased to welcome a diverse, international group of new shareholders who share our vision for the Company.

“Closing this financing with such momentum puts us in an excellent position to pursue aggressive exploration and drilling programs with the objective of delivering for all stakeholders.”

Each Unit comprises one common share of the Company (each, a “Share”) and one-half of one common share purchase warrant (each whole warrant, a “Warrant”). Each Warrant is exercisable by the holder thereof to acquire one additional Share (each, a “Warrant Share”, and together with the Units, Shares and Warrants, the “Securities") at an exercise price of $0.30 if exercised within the first 12 months following the Closing Date and $0.40 if exercised within the subsequent 12-month period, for a total exercise period of 24 months from the Closing Date; provided that: (i) the Warrants shall not be exercisable within the initial 60-day period following the Closing Date, and (ii) the Company will have the right to accelerate the expiry of the Warrants in the event the Shares trade on the TSX Venture Exchange (the “TSXV”) (or any such other stock exchange in Canada as the Shares may trade at the applicable time) at a volume weighted average trading price ("VWAP") of $0.50 or more per Share for a ten (10) consecutive trading day period.

The Units issued under the Offering were offered to purchasers pursuant to the listed issuer financing exemption (LIFE) under Part 5A of National Instrument 45-106 – Prospectus Exemptions and in reliance on Coordinated Blanket Order 45-935 – Exemptions from Certain Conditions of the Listed Issuer Financing Exemption and therefore the Securities issued under the Offering are not subject to a hold period pursuant to applicable Canadian securities laws. There is an amended and restated offering document (the “Offering Document”) related to this Offering that can be accessed under the Company’s profile at www.sedarplus.ca and on the Company’s website at www.tribecaresources.com.

The proceeds from the Offering will be primarily used to advance the Company’s La Higuera IOCG project (the “La Higuera Project”), with additional funds allocated to the planned initial exploration and drilling activities at the exciting new Jiguata Project. The Jiguata Purchase Option (as defined below) remains under review by the TSXV and there is no certainty that the Company will obtain the necessary regulatory approvals, including approval of the TSXV, in respect of the Jiguata Purchase Option.

Tribeca Resources intends to use the net proceeds from the Offering as follows:

Description of intended use of available funds	Estimated allocation of funds
Expenditures relating to exploration activities at the La Higuera Project⁽¹⁾	$1,868,000
Exploration activities at the Jiguata project (the “Jiguata Project”)⁽²⁾	$1,573,000
Reserved for results-dependent follow-up drilling at the La Higuera Project / the Jiguata Project⁽²⁾	$1,331,000
Business development	$181,000
General and administrative	$894,000
Unallocated working capital	$382,000
TOTAL:	$6,229,000

(1) The Company does not currently intend to use the available funds to complete its option to acquire the Gaby target, as more fully described in the Offering Document (the “Gaby Acquisition”). Any decision to pursue the Gaby Acquisition is at the Company’s sole discretion and will require the Company to make a final one-time payment of US$1,550,000.00 on September 15, 2026 (the “Gaby Option Payment Date”) subject to (i) any further negotiation between the Company and the vendor party participating in the Gaby Acquisition (the “Vendor”) for the purpose of extending the Gaby Option Payment Date; and (ii) the Company obtaining additional financing (in addition to the Offering) to complete the Gaby Acquisition. The Vendor is not an insider, associate or affiliate of the Company.
(2) The Company only intends to use the part of the available funds as detailed above for exploration activities at the Jiguata Project if it obtains the necessary regulatory approvals, including approval of the TSXV, to enter into the option to purchase 100% of the Jiguata Project (the “Jiguata Purchase Option”), as more particularly set forth in the Offering Document. In the event that the Company does not obtain all necessary regulatory approvals or approval from the TSXV, the Company will use certain proceeds currently contemplated for the Jiguata Project for other purposes as set out herein and in the Offering Document. The Jiguata Purchase Option remains under review by the TSXV and there is no certainty that the Company will obtain the necessary regulatory approvals, including approval of the TSXV, in respect of the Jiguata Purchase Option. The Company confirms that it has obtained and retained all required consents from purchasers in the Offering in respect of the Jiguata Purchase Option.

In connection with the Offering, the Company paid an aggregate of approximately $248,694 and issued finder’s warrants to acquire up to an aggregate of 1,184,257 Shares (the “Finder’s Warrants”) as finder's fees to certain eligible finders in consideration for introducing certain purchasers to the Company. Each Finder’s Warrant entitles the holder to acquire one Share at a price of $0.21 per Share for a period of twenty-four months. The Finder’s Warrants, and Shares issuable upon exercise of the Finder’s Warrants, are subject to a statutory four-month hold period pursuant to applicable Canadian securities laws.

The Offering remains subject to the final approval of the TSXV.

Related Party Disclosure

Certain insiders of the Company subscribed for approximately $936,046 worth of Units in the Offering. This participation by insiders constitutes a “related party transaction” within the meaning of Multilateral Instrument 61-101 – Protection of Minority Shareholders in Special Transactions (“MI 61-101”). The Company has relied on applicable exemptions from the formal valuation and minority approval requirements in Sections 5.5(a), 5.5(b) and 5.7(1)(a), respectively, of MI 61-101. No new insiders were created, nor has there been any change of control, as a result of the Offering. The Company did not file a material change report with respect to the insiders’ participation more than 21 days before the expected closing of the Offering, as the details and amounts of the insider participation were not finalized until closer to the closing and the Company wished to close the Offering as soon as practicable for sound business reasons.

Wildeboer Dellelce LLP acted as legal counsel to Tribeca in connection with the Offering.

Tribeca Resources to Acquire Option Over Jiguata Porphyry Copper Project in Chile

Tribeca Resources Corporation (TSXV: TRBC) (OTCQB: TRRCF) (“Tribeca Resources”, the “Company”) is pleased to announce it has entered into a letter of intent (“the LOI”) with private vendors (the “Project Vendors”) to acquire a 100% interest in a 10,000 hectare property (the “Jiguata Property”) over a period of 5 years. The Jiguata property, located in northern Chile, 120km north of the major mining company controlled Collahuasi and Quebrada Blanca mines (Figure 1), will be progressed in parallel with the Company’s two existing projects: La Higuera and Chiricuto.

Highlights:

Property
- Large epithermal and interpreted porphyry alteration system in the northern extension of the prolific Chilean porphyry-bearing Eocene-Oligocene Belt. Overprinted and partly covered by rocks of the younger Miocene Belt
- Soil sampling, historic drilling, geological mapping and geophysics highlight a large 5km x 3km exploration target, with two existing discrete near drill-ready targets
- Located 120km north of Collahuasi (Anglo-Glencore-Mitsui) and Quebrada Blanca (Teck-Codelco-Mitsui) at an altitude of 4,200-4,600 meters. Drive-up access via paved Collahuasi road and nearby accommodation
Proposed work
- The agreement allows for a thorough testing with expenditure going into the ground to advance towards a discovery
- Pre-drilling activities at the Jiguata Property will be undertaken in parallel with planned further drilling at the Company’s flagship La Higuera Project
Proposed transaction
- Letter of intent entered to acquire a 100% interest in the Jiguata Property
- US$15 million purchase price over a 5-year option period; including US$14.45 million bullet payment upon option exercise
- Parties will work to enter into a definitive agreement within 90 days of the date of the LOI

Tribeca Resources CEO, Dr. Paul Gow commented:

“We are delighted to be acquiring this significant landholding of 10,000 hectares, which hosts two near drill-ready targets, and extensive blue sky potential that has only been lightly explored. This is an extensive alteration system in northern Chile, a district that hosts truly world-class porphyry copper deposits. The system is exposed through an erosional window in the thin overlying younger Miocene volcanics, whose presence is part of the reason, we believe, that this part of the northern extension of the Chilean Eocene-Oligocene Belt has not been adequately explored. While the project is at an altitude of approximately 4400m, the excellent access and infrastructure and the relatively benign winter at this far northern latitude makes for exploration access much of the year.”

“The pre-existing geoscience database at the project fits with the Tribeca strategy of seeking projects with recognised indications of a potential mineralized system and a well populated database so that drill targets can be firmed up in short order. We look forward to working from this LOI to complete the acquisition over the coming months and commence fieldwork.”

The Jiguata Property

Highlights

34 exploration concessions covering 10,000 hectares
Situated in the northern extension of the prolific Eocene-Oligocene porphyry copper belt of northern Chile, approximately 120km north of the Collahuasi and Quebrada Blanca copper-molybdenum deposits.
Pre-existing geological mapping, soil and rock geochemistry and Induced Polarization (IP) survey and limited historic drill data outline two drill targets, with additional earlier stage targets elsewhere on the property remaining to be detailed with additional field work.
Excellent existing access to the area via a maintained road that passes through the property.

The Jiguata Property is located in the northern extension of the Eocene-Oligocene metallogenic belt of northern Chile (Figure 1), where it has been overprinted by the Miocene magmatic belt. The prolific Eocene-Oligocene Belt hosts the giant Collahuasi, Chuquicamata and Escondida deposits, while the Miocene Belt, further to the south, hosts many of the current crop of high-profile Chilean-Argentine porphyry copper projects including Filo del Sol, Valeriano, Encierro and Altar.

The project area encompasses a large advanced argillic alteration zone (25 square km) hosted within a volcanic tuffaceous unit under a thin blanketing cover of fresh unaltered Miocene dacitic volcanic rocks dated at approximately 9-5 Ma (Figure 2). The alteration zone has been exposed via an erosional window in the overlying Miocene volcanic rocks. The age of the tuffaceous unit hosting the alteration is unknown age but likely Eocene-Oligocene or Miocene. Within the alteration zone, previously unmapped feldspar-biotite-(hornblende) bearing porphyritic units are recognised. The alteration zone is representative of a lithocap and dominated by epithermal mineralogy and textures (e.g. extensive quartz-alunite alteration and the presence of steam-heated, chalcedonic silica and quartz ledges), although porphyry-style veins are present at surface and propylitic alteration and quartz stockwork is recorded from shallow historic drilling. The historic drilling comprised two reverse circulation (RC) drill holes that were completed in 1993 to depths of 250m and 300m. The drill holes appear to have been targeted at silica ‘ledges’ within a large soil molybdenum anomaly (to 867ppm Mo in soils) in the incised valley. Highly anomalous Mo was recorded in the drill holes (e.g. 248m @ 255ppm Mo in drill hole 3546), with copper above background at 250 ppm. Various copper or molybdenum sulphide minerals have been reported from the drilling, including chalcopyrite, bornite, chalcocite and molybdenite.

Figure 2. Oblique view to the NE of the incised advanced argillic alteration system at Jiguata (pale rocks) hosting mapped porphyritic units (in red). A thin cover of Miocene volcanic rocks (dark sub-horizontal unit) cover this alteration zone. The two historic RC drill holes from Codelco (250m and 300m depth) are shown in the southern valley floor.

IP surveying was completed on six one kilometer-spaced lines over part of the project area in 2014, delineating two large chargeability anomalies which coalesce to form a zone of 1.5km x 5km at >20 mV/V (Figure 3), with associated high- and low-resistivity zones, which comprise high-priority near-term drill targets.

The project area is traversed by an existing good quality maintained road (97-B) which is partly asphalted, allowing for rapid access within 3 ½ hours (220km) from the port city of Iquique via the Collahuasi access road (highway 65). The altitude in the project area generally ranges between 4200m-4600m, but the northerly latitude of the project provides only short interruptions to access for exploration activities, with a variably short snow season in July-August and a rainy period (“Bolivian winter”) in January-February. Other companies holding exploration tenure in the general area include, Vale, Codelco, BHP, Teck, Glencore and Antofagasta Minerals.

Tribeca Resources plans to undertake further mapping, surface sampling and additional geophysics prior to proceeding with drilling at the Jiguata Property.

The modelled chargeability sections are shown for lines 5000N and 6000N, which host two high chargeability drill targets. The deep purple colors on the sections represent chargeability values of approximately 30 mV/V.

Chiricuto Project final drill results

Assay results were reported from the first three holes (CHR001 TO CHR003) at the Chiricuto project in the northern Atacama region on 7 May 2025, and included the intersection in CHR001 of a thick (>400m) interval of porphyry-style veining and alteration with a strong sulphide component and three 10-12m intervals of 0.10-0.12% copper with gold up to 0.53 g/t. Final assay results have now been received from the final two holes at Chiricuto (CHR004 and CHR005). The holes tested the weaker southern portion of the IP anomaly drilled by CHR001. Both holes intersected altered andesite and monzodiorite with lesser sulphide and copper mineralization, with the best copper-bearing intervals being:

8m @ 0.14% Cu, 0.06ppm Au, 76ppm Co and 6.4% Fe from 144m in CHR004
6m @ 0.16% Cu, 0.37ppm Au, 31ppm Co and 5.8% Fe from 212m in CHR004

This final data is now being integrated to understand if potential for higher grade copper mineralization exists related to the porphyry-style alteration system intersected in holes CHR001, CHR004 and CHR005.

More detailed information including drilling location maps and drill hole collar details can be found in the news release from Tribeca dated 7 May 2025.

La Higuera Project update

Tribeca intends to recommence drilling at the La Higuera Project in 2H 2025. Targets have been identified from geophysical data and historic drilling under gravel cover on the flanks of the Chirsposo Sur target system, and as follow-up drilling from the 2024 Phase 2 drill program at the Gaby IOCG discovery. Further information on these proposed programs will be released as available.

Tribeca Resources Maiden Drill Program Intersects Porphyry-style Mineralization with Encouraging Gold Values at the Chiricuto Property in the Atacama Region of Chile

Tribeca Resources Corporation (TSXV: TRBC) (OTCQB: TRRCF) (“Tribeca Resources”, the “Company”) is pleased to report the completion of a maiden drill program at the Company’s previously undrilled Chiricuto Property (“Chiricuto”) in the Atacama region of northern Chile. Since acquiring an option to purchase a 100% interest in the property in March 2024, Tribeca systematically completed geological mapping, IP-MT geophysical surveying and soil sampling ahead of the now completed drill program.

Highlights:

5 holes drilled: two targets tested with a combined 1,586m of diamond drilling. Assay data received for the first three holes (CHR001-CHR003)
Copper-gold porphyry-style mineralization intersected at IP-MT target: Hole CHR001, drilled into the northern strong coincident IP chargeability - MT anomaly, intersected a strong sulphide system over most of the hole length (456m) associated with porphyry-style veins and breccias. The pyrite-chalcopyrite sulphide assemblage in the hole is dominated by pyrite, and hosts significant gold values, with the best of several 10-16m thick mineralised zones recording 10m @ 0.12% Cu, 0.47 g/t Au.
Magnetic target tested: The two drill holes (CHR002, CHR003) tested the magnetic target and intersected an IOCG-style magnetite alteration system hosted by breccias and veins. Chalcopyrite is locally present in the drill holes with a maximum individual assay of 0.16% Cu. One zone of semi-massive iron mineralization yielded 18m @ 26.1% Fe (from 102m in CHR003).

The results from the drilling expand our understanding of the copper mineralization in the area. The intersection of copper-gold porphyry-style mineralization was unexpected and provides a new target style that has not previously been the focus of exploration in the area. Next steps will be determined once all drill results are received and integrated and the data from the property can be reviewed in the context of this new geological model.

Tribeca Resources CEO, Dr. Paul Gow commented:

“Drilling at Chiricuto has intersected a strong sulphide system associated with breccias and porphyry-style veins. Sulphide is present nearly all the way down the 456m of hole CHR001, and pleasingly with locally high gold values. We now await the assays from the final two holes of the program, which tested southern extensions of the IP/MT target into which hole CHR001 was drilled, to further refine our understanding of the property's mineralization potential."

Chiricuto Property drilling program

The Chiricuto Property is a 570 hectare property located in the established Mantoverde district of the Chilean Coastal Belt, 15 km and 21 km from Capstone Copper Corporation’s Mantoverde mine and Santo Domingo development project, respectively. These two deposits combined host over 1.5Bt of copper-gold mineral resources (Figure 1). The Mantoverde mine produced 35,000 tonnes of copper cathode per in 2024, with a recently completed expansion to process sulphide ores set to increase total production in 2025 to between 97,000 tonnes and 112,000 tonnes of copper.

Tribeca completed a drilling program at Chiricuto that tested two key geophysical targets for copper-gold mineralization. The program comprised five drill holes for 1,586m, with hole depths ranging from 250m to 456m.

IP/MT Target: The first target is characterized by a significant 1.2km-long gradient array Induced Polarization (IP) chargeability anomaly in the northwest of the property (Figure 2). The northern end of the target has a magneto-telluric (MT) low-resistivity anomaly (<200 ohm-m) present from close-to-surface to +500m depth. This zone is coincident with strong gold anomalism in soil (to 0.127 g/t Au) and mapped chlorite-epidote and chlorite-silica alteration at surface.

The target was tested by three 400m-spaced drillholes (CHR001 – 456m, CHR004 – 323m, CHR005 – 250m). Assay results have been received from CHR001, with the best copper intervals provided in Table 1. CHR001 intersected significant porphyry-style veins and lesser stockwork associated with hydrothermal breccias within an andesite host rock intruded by diorite, monzonite and andesitic dikes (Figure 3a). The vein mineralogy is dominated by quartz or quartz-pyrite, locally with K-feldspar haloes. Actinolite-chlorite-silica alteration is strongly developed, and tourmaline is variably present in the hydrothermal breccias. Chalcopyrite is locally present both disseminated and in veins, commonly with carbonate (Figure 3c). The sulphide system is strong, with sulphide visible throughout much of the 456m in CHR001. Assay results indicate an average sulphide content of approximately 3.8% consistently distributed throughout the entire hole, albeit strongly pyrite-dominated. This strong sulphide system encountered in CHR001 is consistent with the MT low resistivity anomaly present in the 3D inversion in this area. Copper is present in much of the hole at levels of ~600ppm, with three zones of >0.1% Cu (Table 1). Molybdenum and cobalt are variably anomalous and not strongly correlated with copper or gold, but are locally anomalous with maximum individual 2m assay results of 96ppm Mo (from 8m) and 252ppm Co (from 44m), indicating potential for a multi-element mineralization system. Strong iron oxide alteration is not common in CHR001, with only local bands or veins of magnetite or specularite, commonly with pyrite (Figure 3b).

Table 1. Summary of significant copper mineralized intersections in drill hole CHR001

HoleID	From (m)	To (m)	Downhole Interval (m)	Copper (%)	Gold (g/t)	CuEq (%)	Cobalt (ppm)	Molybdenum (ppm)
CHR001	76	86	10	0.12	0.47	0.46	55	16
CHR001	244	260	16	0.10	0.03	0.12	19	15
CHR001	434	446	12	0.11	0.53	0.50	30	<1

Note: Intervals compiled at an approximate 0.1% Cu cut-off. Copper equivalent (“CuEq”) values are calculated using metals reported in situ (100% basis) and only including copper and gold values. Assumptions include metals prices of US$4.00/lb for copper and US$2000/oz for gold. No metallurgical data is available so there are no discounts for recovery. The formula used is as follows: CuEq% = Cu% + 0.72 x Au g/t

Magnetic Target: The second target comprises a large (800m by 400m) and intense (3500nT) ground magnetic anomaly interpreted as sourced by a magnetite alteration system (Figure 2). Two holes (CHR002 and CHR003) were drilled to depths of 260m and 296m, respectively, to test this system. Both holes intersected significant magnetite-actinolite-albite alteration. Copper sulphide (chalcopyrite) is present at trace levels in CHR002 and CHR003, most commonly within, and as haloes to, carbonate veins. Specularite is also locally present in these veins. The highest individual copper assay was 0.16% Cu in a 2-metre sample from 272m in CHR003, with the maximum iron assay for an individual 2-metre sample being 38.3% Fe within an interval of 18m @ 26.1% Fe from 102m in CHR003 (Figure 3d), demonstrating notable iron mineralization.

The collar information for all five holes is provided in Table 2.

Plans for 2025

Tribeca is actively finalizing plans for a Phase 3 drill program at its cornerstone La Higuera IOCG Project, demonstrating its commitment to advancing its key assets. Concurrently, the company is aggressively pursuing business development initiatives, both near its existing two projects and in Chile more broadly. The company is currently evaluating all available data from the Chiricuto program to determine the best path forward for the property, including potential partnerships and alternative exploration strategies. This comprehensive approach is intended to ensure that Tribeca maximizes the value of its assets while maintaining a disciplined and strategic focus.

Notes on sampling and assaying

Analytical samples were produced using ½ HQ core and sent to the Activation Geological Services (AGS) Lab in La Serena, Chile. Preparation included crushing the core samples to 70% < 2.5mm and pulverizing 500g of crushed material to better than 95% < 105 microns. All samples are assayed using 30g nominal weight fire assay with AAS finish (Au-FA30) and a multi-element four acid digest ICP-OES method (OES-TD36). The QA/QC procedure for this drilling program utilizes field duplicates, standards and blanks that comprise approximately 10% of the total samples submitted.

Tribeca Resources Commences Maiden Drill Program at Chiricuto Property in Atacama Region of Chile

Tribeca Resources Corporation (TSXV: TRBC) (OTCQB: TRRCF) (“Tribeca Resources”, the “Company”) is pleased to report that drilling has commenced on the Company’s Chiricuto Property (“Chiricuto”) in the Atacama region of northern Chile. This follows systematic completion of geological mapping, geophysics and soil sampling since Tribeca Resources acquired an option to purchase a 100% interest in the property in March 2024.

Highlights:

Untapped Potential: Chiricuto is home to one of the few remaining large iron oxide alteration systems in the Capstone Copper dominated Mantoverde copper district, that has not yet been explored through drilling
Commencement of Drilling: Drilling under way to investigate two targets validated through a combination of geochemical, geological, and geophysical surveys
Planned Drilling: Approximately 1,500 meters of planned diamond drilling to be executed across five strategically proposed drill holes. This program aims to thoroughly assess the mineral potential

Drilling activities at the Chiricuto Property will be undertaken in parallel with preparation for further drilling at the Company’s flagship La Higuera Project.

Tribeca Resources CEO, Dr. Paul Gow commented:

“Since Tribeca Resources’ acquisition of a 100% purchase option over the Chiricuto Property ten months ago, our team has worked to systematically complete three streams of pre-drilling activities and has successfully advanced the Chiricuto Property towards this significant milestone. We are excited to now test these exciting combined geophysical-geochemical targets in this growing copper district that is dominated by Capstone Copper’s significant copper-gold projects.“

Chiricuto Property drilling program

The Chiricuto Property is a 570 hectare property located in the established Mantoverde district of the Chilean Coastal Belt, 15 km and 21 km from Capstone Copper Corporation’s Mantoverde mine and Santo Domingo development project, respectively. These two deposits combined host over 1.5Bt of copper-gold mineral resources (Figure 1). The Mantoverde mine currently produces 35,000 tonnes of copper cathode per annum, with a recently completed expansion to process sulphide ores set to increase total production in 2025 to between 97,000 tonnes and 112,000 tonnes of copper.

Geochemical-geophysical targets, coincident with mapped alteration, at the Chiricuto Property will be tested by an approximate 1,500m diamond drilling program expected to include five drill holes, the first of which has been collared. The objective of this maiden drill programme is to test for significant iron oxide copper-gold (IOCG) mineralization associated with one of the few remaining large iron oxide alteration systems in the district yet to be drill tested.

The two key targets to be tested for copper-gold mineralization comprise i) a large magnetic anomaly in the west of the property, which is expected to be associated with magnetite alteration, and ii) a significant IP chargeability anomaly in the northwest of the property that is generally non-magnetic and is interpreted as potentially associated with hematite alteration.

Pre-drilling activities completed at Chiricuto

The pre-drilling activities undertaken during 2024, to identify these targets at Chiricuto, included:

Geological mapping that identified extensive alteration zones, predominantly focused in the northwest of the property (Figure 2)
Gradient-array Induced polarization (IP) and magneto-telluric (MT) geophysical surveying that identified a 1.2km long chargeable zone in the northwest of the property (see Tribeca’s news release dated 29 October 2024)
Systematic soil sampling over the area covering both the IP and ground magnetic anomalies, which returned the two highest copper samples over the two key geophysical anomalies, along with highly elevated gold up to 0.127 g/t Au (see Tribeca’s news release dated 15 January 2025)

Figure 2. Summary soil geochemistry copper/gold results. The key gradient array IP anomaly in the northwest of the property displays coincident copper and gold anomalism in the soil data. Copper anomalism (to 935 ppm Cu) is also coincident with the strong magnetic anomaly in the central-west area.

Tribeca Resources announces encouraging soil geochemistry results coincident with geophysical targets ahead of drilling at Chiricuto

Tribeca Resources Corporation (TSXV: TRBC) (OTCQB: TRRCF) (“Tribeca Resources”, the “Company”) is pleased to announce results from a systematic soil geochemical survey over the geophysical targets at the Chiricuto IOCG Property ("Chiricuto Property") in the Atacama region of northern Chile. Strong copper and gold soil anomalism is present and is associated with Induced Polarization (IP) and ground magnetic targets that are proposed for drilling in the coming months.

Highlights:

Highly anomalous copper and gold soil samples with values up to 935 ppm copper and 0.127 g/t gold
Two highest copper samples located directly over the two most significant geophysical anomalies: one over the intense ground magnetic anomaly, one over a coincident gradient array IP chargeability and magneto-telluric (MT) low-resistivity anomaly
Documentation for the upcoming drilling program submitted to the appropriate authority (Sernageomin), with drilling expected to commence in February

Drilling activities at the Chiricuto Property will be undertaken in parallel with preparation for further drilling at the Company’s flagship La Higuera Project.

Tribeca Resources CEO, Dr. Paul Gow commented:

“Integration of the new soil geochemistry data with our recently reported geophysical survey results reinforces our proposed drill targets at Chiricuto. These now represent exciting combined geophysical-geochemical targets in this growing copper district, dominated by Capstone Copper Corp. The very strong gold soil results accompanying the anomalous copper are highly encouraging, and consistent with the metals commonly present in IOCG systems. We look forward to commencing drilling at Chiricuto in the coming month.”

Chiricuto Project overview

The project is located within the andesite-dominated lower unit of the Middle-Upper Jurassic La Negra Formation, which is the same rock unit that hosts the Mantoverde deposit (approximately 1 Billion tonnes of oxide and sulphide copper resource, Capstone Copper MRE dated 31 December 2022 - Measured and Indicated categories). The rocks are in the hanging-wall to a major east-vergent thrust, parallel to, but located between, the regional Atacama and Chivato Fault Systems.

Much of the Chiricuto Property area is located under interpreted thin alluvial or colluvial gravel cover, however outcrop is locally present and hosts several small copper or iron workings and pits.

The Chiricuto soil sampling program

A systematic 200m x 200m spaced grid soil sampling program was completed over the previously announced geophysical targets at the Chiricuto Property (see Tribeca’s news release dated 29 October, 2024). The objective of the soil survey was to delineate zones of higher copper-gold within the extensive geophysical target area in order to prioritize and refine drill targets for the upcoming drill program. The survey spanned approximately 2.5km x 200m-1,000m of outcropping to sub-cropping area in the northwest of the property (Figure 2). The sampling comprised collection of a 200 gram sample of material finer than 180 microns (-80#) from 30 cm depth. The samples were analyzed at ALS laboratories for a multi-element package plus super-trace gold (ALS code AuME-ST43).

The maximum gold and copper values returned were 935 ppm Cu and 0.127 g/t Au. The maximum copper value was returned from over the intense >3,000 nT magnetic anomaly in the central-west of the property. The second highest copper anomaly was returned from the northwest of the property coincident with a prominent gradient array chargeability anomaly and magneto-telluric (MT) low-resistivity anomaly (Figure 2). Importantly, this zone of copper anomalism also hosts a 400m x 300m zone of gold in soil of >50 ppb Au (0.05 g/t Au), with two samples above 0.1 g/t Au.

Upcoming drilling program

These coincident geochemical-geophysical targets at the Chiricuto Property are planned to be tested by an approximate 1,500m diamond drilling program expected to commence in February. The requisite documentation has been submitted to the appropriate authority (Sernageomin) and the drilling contractor has been appointed.
