Projects

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 0.86% Cu, 0.64 gpt Au and 53 metres of 0.31% Cu, 0.2 gpt Au which was not followed up on. New interpretations based on recent geologic mapping by the British Columbia Geological Survey (BCSC) 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.

In 2021, Libero completed an initial detailed mapping program which helped substantiate the recent geological model proposed by the BCGS that describes the spatial distribution and timing of the multiphase Big Bulk porphyry. The mapping was used to refine 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 2021 drill campaign consisted of 5 diamond drill holes totalling 1,743 meters. The drill program was successful at targeting an east-west striking tabular body of mineralized phase 2 diorite (quartz-chalcopyrite veined) that partially outcrops and dips moderately to the south. Drill hole BB-21-01 intersected 37.44 metres of 0.3% Cu, 0.59 gpt Ag, 0.15 gpt Au) including 9.5 metres of 0.43% Cu, 0.79 gpt Ag, 0.2 gpt Au. Drill hole BB-21-05 intersected 97 metres of 0.19% Cu, 0.97 gpt Ag, 0.18 gpt Au including 17.5 metres of 0.28% Cu, 1.29 gpt Ag, 0.23 gpt Au. The target remains open 200 metres below surface.

Big Bulk is fully permitted and drill-ready with a 2,000-metre diamond drill program planned for the future.

Quality Assurance / Quality Control on Sample Collection, Security and Assaying

Libero Copper operates according to rigorous Quality Assurance and Quality Control (QA/QC) protocols consistent with industry best practices. All sample assay results have been monitored through a quality control/quality assurance (QA/QC) programme including the insertion of blind standards, coarse blanks, and duplicate samples. Monitoring of the QA/QC programme has determined that the analytical results are of acceptable quality. Assay samples are securely transported to ALS Global's sample preparation facilities in Terrace, BC and Langley, BC. Sample pulps are analysed in North Vancouver, British Columbia for gold by fire assay using a 30-gram charge with atomic absorption spectroscopy (AAS) finish. Samples which exceed 9 g/t gold trigger a 30-gram fire assay with a gravimetric finish. Copper and silver contents are determined by four-acid digestion with ICP-AES finish. ALS Global is an independent laboratory. Libero Copper is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data.

Quality Assurance / Quality Control and Sample Data Validation (historic data)

The company has incorporated materials from previous Assessment Reports that are filed for the claims covering the Big Bulk property. These reports include details related to sample locations, sample procedures, protocols, assay results, assay lab details, assay procedures, etc. The company has resampled and mapped historic locations that contain elevated mineralization to further validate and evaluate the economic potential of previous sample results.
