Tribeca Resources Drills 82 metres of 0.41% Copper Within 224 metres of 0.31% Copper 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 results from the first diamond hole of the Phase 2 drilling program at the Company’s La Higuera Project (“the Project”) in the Coastal Iron Oxide Copper-Gold (IOCG) Belt of northern Chile. Drill hole GBY008 intersected a thick interval of copper-gold mineralization from the base of shallow gravel cover.


  • Drill hole GBY008 intersected an interval of 82 metres at 0.41% copper, 0.07 g/t gold. within 224m @ 0.31% copper, 0.06 g/t gold in IOCG-style mineralization from the base of gravel cover at 50m down hole depth
  • Two additional holes, GBY009 and GBY010, have been completed and are currently being logged and sampled
  • Drilling continues with a key objective of the programme being to test approximately 650 metres of additional strike length at the northern end of the 1km long mineralized Gaby copper-gold discovery

Drill hole GBY008 was a 50m step-back from the previously reported GBY001 and has confirmed the significant thickness of mineralization and provided important constraints for the geological model. In particular, the hole provided information on the potential geometry and distribution of the magnetite breccias that are the main hosts for the copper-gold mineralization.

The assay results from the current and upcoming holes in this 10-hole program of approximately 4,000 metres are planned to be released progressively as they are received, with drilling expected to continue until February 2024.

Tribeca Resources CEO, Dr Paul Gow commented:

“The first hole in this new drilling program intersected a zone of strong magnetite breccia hosting well developed copper-gold mineralization. The thickness and relatively shallow depth of the intersection in this hole underscores the significance of our recent IOCG discovery at Gaby.”

“We look forward to releasing further results from the program over the coming months as we test both strike extensions to the north and new geophysical targets.”

Table 1. Summary of significant mineralized intersections in drill hole GBY008.

HoleID From (m) To (m) Downhole
Interval (m)
Co (ppm) CuEq
GBY008 50 274 224 0.31 0.06 208 0.36
incl. 50 56 6 0.82 0.17 147 0.85
incl. 90 116 26 0.42 0.10 99 0.45

incl. 190 272 82 0.41 0.07 409 0.50

Note: Apart from the summary intersection (from 50-274m) and the interval from 50-56m, 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$3.50/lb copper, US$1,900/oz gold and US$15.88/lb cobalt.

Drill hole GBY008 discussion

Drill hole GBY008 was designed as a 50m step-back from drill hole GBY001 on Section 4270N (Figures 1 and 2) with the objective of testing the mineralised system to the east and providing constraints on the geometry of the mineralized breccias. The hole was terminated at 445.5m depth. The drill hole lifted more than expected and at depth is within 13m of GBY001. It intersected the same diorite body near the base of the hole as that seen in GBY001.

As previously reported in results from drill hole GBY001 (news release dated 30 January 2023), which intersected 268m @ 0.66% Cu and 0.14 g/t Au, the mineralization is dominated by veins and breccias comprising a magnetite-pyrite-chalcopyrite assemblage, commonly associated with combinations of quartz, actinolite, scapolite, albite, and epidote.

The mineralized interval, from the base of cover at 50m to 274m downhole depth, appears to be terminated or offset by a fault at 272-274m, which needs further investigation. The orientation of this fault is not currently known, but it may be a steep fault with horizontal displacement. Magnetite breccias are present below this fault but are less well mineralised (Figure 1). Several late dikes (<5m thick) were also intersected, which crosscut the breccia but are weakly mineralized suggesting a late-mineralization timing. These are not shown on Figure 1. This thick mineralised interval intersected by GBY008 provides significant encouragement as drilling continues to expand the known mineralized zone within this target.

Figure 1. Cross-section 4270N with the location of GBY008 shown. Drill hole GBY010, drilled back from the west, has been completed with logging and sampling in progress. The orientation of the faults as shown is unconstrained. The histogram bars showing copper grade in GBY001 have been top-cut at 2% Cu.

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 4,147 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.
