Tribeca Resources Corporation (TSXV: TRBC) (“Tribeca Resources”, the “Company”) is pleased to announce results from two 250m step-out drill holes, adding 500m of additional strike length for a total of 1 km to this discovery at the Gaby target. This new discovery is part of the Company’s La Higuera iron oxide copper-gold (IOCG) project, located in the Coquimbo region of northern Chile.
The two holes reported here have intersected an interpreted approximately 130m-wide NNW-trending sub-vertical zone of magnetite-related IOCG-style copper sulphide mineralization.
Tribeca Resources CEO, Dr Paul Gow commented:
“These drill results are highly encouraging and further validate our approach of aggressively stepping out to drill well-reasoned geophysical targets under thin gravel cover.”
“Located at just 450 metres above sea-level, and 10 km from the coast, the La Higuera project benefits from extremely favourable access to infrastructure and the possibility of year-round drilling. We look forward to continuing our efforts to increase the known size of this mineralized system during 2023.”
Table 1. Summary of significant mineralized intersections in drill holes GBY006 and GBY007.
Note: Apart from the summary intersections (from 26-262.7m in GBY006 and 88-352m in GBY007) the grade intersections are calculated over intervals >0.2% 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$4.10/lb copper, US$1,965.80/oz gold and US$15.84/lb cobalt (based on 30 March 2023 closing spot prices).
The presence of an approximately 130m-wide NNW-trending sub-vertical mineralized envelope has been interpreted at the Gaby target. It has now been intersected in four drill holes (RCH-LH-07, GBY001, GBY006 and GBY007) on four drill sections over a 650m strike length. Together with thinner, but consistent intersections on the southern end of the zone (RCH-LH-03, RCH-LH-09 and RCH-LH-11) this provides a known strike length of 1km. The mineralization is typically present from the base of thin gravel cover that ranges in thickness from 0 to 76m.
Details of the two new drill holes reported here are as follows:
The holes reported here were drilled at an angle of 60°, such that if the body is vertical as interpreted the true thickness will be approximately half of the downhole thickness.
Figure 2 provides an overview of the gravity and additional ground magnetic data collected in Q4 2022 at the Gaby target. The interpretation of magnetic susceptibility data conducted on the project has yielded valuable insights, and the magnetite-associated mineralization drilled to date shows a strong spatial correlation with moderate intensity magnetic anomalism (approximately 1000 nT). The moderate magnetic trend continues to at least 400m north of drill hole GBY007.
A strong gravity anomaly of approximately 1 mGal intensity is present 400m to the east of drill hole GBY007, and is coincident with a small copper showing on sporadic outcrop. This provides an additional significant exploration target.
Analytical samples were collected using 1/8 of the material from each 2m interval for the reverse circulation drilling or ½ HQ core for the diamond drilling and sent to the ALS Laboratory in La Serena, Chile for preparation and then to ALS in Santiago, Chile and Lima, Peru for analysis. Preparation included crushing the RC and 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 an ore grade four acid digest method (Cu-OG62). The QA/QC procedure for this drilling program utilizes field duplicates, certified reference standards and blanks that comprise approximately 10% of the total samples submitted. The QA/QC results indicate appropriate accuracy and precision in the assaying program.

Tribeca Resources is a copper exploration company focused on discovering and developing assets in the Coastal IOCG Belt of northern Chile. The company’s management team, whose members are significant shareholders of the Company, has 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’s flagship property is the La Higuera IOCG project that comprises 4,047 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 can be found in the NI 43-101 Technical Report lodged by Tribeca on SEDAR on 24 October 2022.
