Libero Copper & Gold Corporation reported assay results for the five hole, 1,743 metre drill program at the Big Bulk porphyry copper project in British Columbia'sGolden Triangle. Results suggest the presence of a large mineralizing system, with new drill results confirming a greater than two kilometre strike length. Libero Copper's first drill program on Big Bulk tested a new geological model derived from recent mapping by the British Columbia Geological Survey which indicates the target is a much larger calc-alkaline porphyry system with similarities to KSM.

The targeted intrusive phase (Phase 2 – quartz-chalcopyrite veined hornblende diorite) of the Big Bulk porphyry was intersected in multiple holes. Drill hole 1 intersected 37.44 metres of 0.42% CuEq (0.3% Cu, 0.59 g/t Ag, 0.15 g/t Au) including 9.5 metres of 0.59 CuEq (0.43% Cu, 0.79 g/t Ag, 0.2 g/t Au). Drill hole 5 intersected 97 metres of 0.34% CuEq (0.19% Cu, 0.97 g/t Ag, 0.18 g/t Au) including 17.5 metres of 0.47% CuEq (0.28% Cu, 1.29 g/t Ag, 0.23 g/t Au).

The Big Bulk porphyry copper-gold project is a multiphase late Triassic intrusion hosted in Hazelton and Stuhini volcanic and sedimentary rocks analogous to the district which hosts the KSM and Brucejack deposits. Big Bulk is located 20 kilometres north of Kitsault, BC, and borders Dolly Varden Silver's Big Bulk project and Hecla Mining's Kinskuch project. The project was initially explored by Teck and Canadian Empire from 2001 to 2003.

Drilling in 2003 intercepted 21 metres of 1.35% CuEq (0.86% Cu, 0.64 g/t Au) and 53 metres of 0.46% CuEq (0.31% Cu, 0.2 g/t Au) which was not followed up on. New interpretations based on recent geologic mapping by the British Columbia Geological Survey indicate that the target is a much larger calc-alkaline porphyry system tilted on its side with higher grade mineralization in a discreet mineralized phase that was not targeted by historic drilling. Exploration work during the 2021 field season consisted of an initial detailed mapping program which helped substantiate the recent geological model proposed by the British Columbia Geological Survey (BCGS) that describes the spatial distribution and timing of the multiphase Big Bulk porphyry.

The mapping was used to refine the proposed drill targets and determine areas suitable for construction of drill pads. The initial mapping confirmed wide zones of high-grade copper mineralization (primarily occurring as chalcopyrite) at surface, as well as a historic showing hosting visible gold. The drill program was designed to test the model of an east-west striking tabular body that partially outcrops and dips moderately to the south.

Drilling in 2021 tested the strike length of the Phase 2 diorite over 2 kilometres. The drilling tested the location of the Phase 2 intrusion in 5 separate large fault blocks that are bounded by late north-south oriented structures. Drilling successfully intersected moderate to strong mineralization in drill holes 1 and 5, where the mineralized intervals exhibited many of the characteristics of the Phase 2 diorite.

Alteration in hole 1 occurs as pervasive propylitic alteration, mineralization is subtle, largely consisting of very fine-grained chalcopyrite. Mineralization in hole 5 occurs as blebby vein pyrite and local coarse chalcopyrite that is associated with strong phyllic and argillic alteration overprinting weal propylitic and local potassic alteration. Holes 2 and 3 exhibit short zones of anomalous copper mineralization, as well as wide zones of propylitic alteration, locally exhibiting an argillic overprint.
