Tribeca Resources extends IP anomaly north of the

Gaby discovery at the La Higuera IOCG project

Tribeca Resources Corporation (TSXV: TRBC) (OTCQB: TRRCF) (“ Tribeca Resources”, the

“Company”) is pleased to announce results from extension geophysical surveying (Induced

Polarization - IP) at the Gaby discovery, which is part of the La Higuera IOCG project in

northern Chile. The results provide new chargeability anomalies that significantly extend

the chargeable zone at Gaby to the north, providing encouragement that recently

intersected mineralization continues beyond the limits of current drilling.

Highlights:

 Two lines of extension IP geophysical surveying at the northern end of the Gaby

IOCG target have returned significant IP chargeability anomalism, up to 26 mV/V in

inverted data, consistent with the presence of disseminated sulphide minerals. The

new data extends the chargeable zone at Gaby by an additional 600m to the north.

 The eastern line (1400E) also identified a promising coincident low resistivity – high

chargeability anomaly at its southern end, which presents a strong drill target, and

is located in the vicinity of small historic pits hosting both oxide and chalcopyrite

copper mineralization.

This IP survey was designed to test the area to the north of the Gaby discovery, where

ground magnetic and gravity anomalism are present, but not coincident. Chargeability

anomalism consistent with sulphide mineralization has been recorded adjacent to the

previously reported 1mGal gravity anomaly. This data is supportive of mineralization

intersected in the northernmost hole of the last program (e.g. 264m @ 0.31% Cu, 0.06 g/t

Au in GBY007) continuing further to the north.

Tribeca Resources CEO, Dr Paul Gow commented:

“These are excellent results from the extension IP surveying at Gaby, which significantly

extend the one-kilometre-long chargeability anomaly we have been successfully drilling.

Off the back of our recently announced financing, we are now preparing for the Phase 2 drill

program in which we will drill further north under cover and attempt to expand the known

size of this copper-gold system.”

IP Geophysical Survey

The IP survey comprised two lines, for 4.4 line-kilometres, located approximately 650

metres apart (Figure 1). The survey lines were configured in a NNE orientation (025°),

slightly oblique to the north-south lines historically surveyed in the area, in order to avoid

additional infrastructure (a road upgrade and new transmission powerline) erected in the

area since the original surveying in 2004-2008.

The survey used a 100m pole-dipole array and utilized a n=1 to 20 configuration that

nominally represents a greater depth penetration than previous surveying at the target in

2004-2008, which utilized a n=1 to 6 configuration. The survey was undertaken by the same

contractor that completed the original survey.

Line 750E

 Line 750E hosts an 800m long +20 mV/V chargeability anomaly, peaking at 26 mV/V

in the inverted data. The resistivity inversion indicates a resistive basement in this

zone, beneath a highly conductive horizontal layer that represents the gravel cover

and weathered top of basement.

 Importantly, this line indicates that the 20 mV/V chargeable anomalism defined in

the historical surveying continues to the north. The two drillholes that have pierced

this cross-section (GBY006 and GBY007) are on the flank of and within the southern

portion of the anomaly, with both intersecting significant copper-gold

mineralization.

 This chargeability anomaly represents a strong drill target and given the NNE

orientation of the survey line there is also potential that the mineralization drilled to

date may also expand, or trend, towards the east off the current north-south zone

drilled to date.

Line 1400E

 Line 1400E hosts a strong coincident chargeability and low resistivity anomaly at its

southern end. The geometry of the anomaly suggests a potentially north-dipping

low resistivity zone. Drilling in the two holes to the west, 30-60m off-section,

encountered intervals of copper mineralization towards the end of the holes (e.g.

22m @ 0.15% Cu in RCH-LH-12 and 14m @ 0.24% Cu in RCH-LH-10). These

coincident chargeability and low resistivity anomalies represent a new drill target

well east of Tribeca’s drilling to date.

 The northern end of Line 1400E hosts a chargeability anomaly of 17-19 mV/V

amplitude (Error! Reference source not found.), evident over approximately 450m

length of the line. It is not known if this is related to the highly chargeable zone in

the northern end of Line 750E.

Together the two new lines of IP data provide strong encouragement for the extension of

mineralization to the north of current drilling and provide an additional target to the east of

the main Gaby trend.

Notes on geophysical surveying

The Induced Polarization (IP) surveying reported here was completed by Argali Geofisica

E.I.R.L., which is a longstanding and reputable Chilean geophysical contracting and

consulting company. The IP data were acquired with the pole-dipole array and a dipole

spacing of 100 m expanded through 20 separations (n= 1 to 20). A time-domain waveform

with a frequency of 0.125 Hz was employed. Survey location was determined by handheld

GPS using the Prov. S. America 1956 (mean) datum, which has been converted by the

Company to the WGS84 datum.

developing assets in the Coastal IOCG Belt of northern Chile. The Company’s management

team, whose members are significant shareholders of the Company, have world-leading

expertise and a discovery history with iron oxide copper-gold deposits in the world’s great

IOCG Belts of the Carajás district in Brazil and the Gawler and Cloncurry provinces of

Australia.

Tribeca Resources’ objective is to provide the mineral resources for the next generation of

copper mines in Chile. It is focused on building a portfolio of projects, with emphasis on

mid to advanced-stage copper exploration and resource development projects. To this

end, mineral targets are regularly assessed in pursuit of acquisition, strategic exploration

and significant discovery.

Tribeca Resources’ flagship property is the La Higuera IOCG project that comprises 4,147

hectares of granted mining and exploration licences and is located towards the southern

end of the Chilean Coastal IOCG Belt in the Coquimbo Region of northern Chile. The 822

hectare Gaby concession area is held under a purchase option (5% Exploration Levy on

expenditure incurred during the option period; a US$2 million final payment due March

2024; with a 1% NSR Royalty granted to the owner), with the remainder of the concessions

being outright owned (100%) by Tribeca Resources. Further information about the project
