Tribeca Resources Extends Gaby Discovery Strike Length by 400 Meters and Intersects 105 Meter Wide Mineralized Interval at its La Higuera Copper-Gold Project in Northern Chile

Tribeca Resources Corporation (TSXV: TRBC) (OTCQB: TRRCF) (“Tribeca Resources”, the “Company”) is pleased to announce the extension of the mineralized system at the Company’s La Higuera Project (“the Project”) in the Coastal Iron Oxide Copper-Gold (IOCG) Belt of northern Chile. Drill hole GBY013, which intersected broad mineralization over 105 meters downhole depth, has added approximately 400 meters strike length to what is now a 1,400 metre long system at the Gaby discovery.

Highlights:

• Drill hole GBY013, a 400 meter step-out from drill holes GBY007 and GBY0012, intersected 105 metres at 0.18% copper and 0.04 g/t gold from 331 meters downhole within strong magnetite breccias.
• This intersection expands the known strike extent of mineralization from 1 kilometer to 1.4 kilometers.
• Drilling of the final three holes in the drill phase, sited to test two geophysical anomalies (gravity and IP) to the east of the main mineralized trend and to test the undrilled 400m strike length between GBY007 and GBY013, has been completed with the holes being logged and processed.

The two holes reported here were designed to test continuity of the currently known mineralized system to the north of its existing 1km strike length.

Drilling for this Phase 2 program has now concluded, with 10 drill holes completed for a total of 3,806 meters. Assay results are awaited from the final three holes.

Tribeca Resources CEO, Dr Paul Gow commented:

“With these latest results we have significantly grown what is now a meaningful shallowly covered copper-gold system in a great location and jurisdiction, near abundant existing infrastructure and located only 10 kilometers from the coast.”

“The data from this drill phase has added a further approximately 40% to the strike length of the known system. It is currently being integrated with existing datasets in order to clearly understand the controls on mineralization and plan for further drilling at this emerging discovery.”

Table 1. Summary of significant mineralized intersections in drill hole GBY013.

Note: Apart from the summary intersections in GBY013 (331-436m), the grade intersections are calculated over intervals >0.20% Cu with maximum internal dilution of 10m @ 0.05% Cu and a minimum interval width of 10m. CuEq (%) grades have been calculated using recoveries from metallurgical test work undertaken in 2006 on drill core from the Project, which are 90% for copper, 65% for gold and 50% for cobalt. Metal prices utilised were US$3.50/lb copper, US$1,900/oz gold and US$15.88/lb cobalt.

Drill holes GBY013 and GBY014 discussion

Drill hole GBY013 comprised a 375 metre step-out to the north (Figure 1) from drill holes GBY007 (264m @ 0.31% copper, 0.06 g/t Au) and GBY012 (172m @ 0.23% copper, 0.05 g/t gold). Drill hole GBY013 penetrated 56m of gravel before hitting moderately-altered andesites. The drill hole intersected a strong magnetite alteration system, including magnetic breccias, with a significant mineralized section from 331m to 436m downhole depth. The intersection yielded 105m @ 0.18% copper, 0.04 g/t gold in a chalcopyrite-pyrite-magnetite-amphibole-quartz-scapolite assemblage. The mineralization is dominantly hosted in vein networks, with the higher grades (the maximum individual 1 metre assay returned 1.2% copper) associated with zones of magnetite breccia.

Drill hole GBY014 was a further 200m step-out to the north from hole GBY013 (Figure 1). GBY014 penetrated 67m of gravel followed by weakly altered andesite. The hole did not intersect significant mineralization, with a maximum 2m interval of 0.18% copper.

The intersection of magnetite breccia-related copper-gold mineralization in GBY013 means that this structurally-controlled alteration and breccia system, with attendant mineralization, has been intersected over approximately 1,400m of north-south strike length. The additional drill data suggests the broad envelope to the mineralized breccia system is trending to approximately 350° (Figure 1). Alteration was present in GBY014, but weaker than seen elsewhere in other holes drilled into the system, suggesting the system has weakened or potentially been displaced laterally or vertically.

The 60° dip of the drillholes and the interpreted vertical orientation of the mineralized body suggest true thicknesses will be approximately 50% of the downhole thickness.

Notes on sampling and assaying

Analytical samples were produced using ½ HQ core and sent to ALS Lab in La Serena, Chile for preparation and then to ALS Labs in Santiago, Chile and Lima, Peru for analysis. Preparation included crushing the core samples to 70% < 2mm and pulverizing 1000g of crushed material to better than 85% < 75 microns. All samples are assayed using 30g nominal weight fire assay with AAS finish (Au-AA23) and a multi-element four acid digest ICP-AES method (ME-ICP61). Where the ME-ICP61 results were greater than 10,000 ppm Cu the assays were repeated with ore grade four acid digest method (Cu-OG62). The QA/QC procedure for this drilling program utilizes field duplicates, standards and blanks that comprise approximately 10% of the total samples submitted. The QAQC results indicate good accuracy and precision in the assaying program.
