VANCOUVER, BC, Nov. 6, 2024
/CNW/ - Libero Copper & Gold
Corporation (TSXV: LBC) (OTCQB: LBCMF) (DE: 29H)
("Libero Copper" or the
"Company") is pleased to announce the details of its
ongoing 14,000-metre exploration program at the Mocoa porphyry
copper-molybdenum project. The extensive program, which combines
infill, step-out, and regional drilling, is designed to expand the
resource, enhance geological understanding, and test new target
areas as part of Libero Copper's
commitment to advancing Mocoa. The flagship Mocoa porphyry
Copper-Molybdenum deposit is Libero
Copper's flagship asset, located within the prolific
Jurassic Copper Belt, in Colombia
near the town of Mocoa, Putumayo.
Highlights
- Significant Resource Expansion Potential with 14,000 Metres
of Drilling: This program increases the total historical
drilling at Mocoa by nearly 50%, with a focus on infill and
step-out drilling. Targeted zones aim to expand high-grade copper
(Cu) and molybdenum (Mo) areas, designed at enhancing the
understanding of the overall resource potential.
- Exploration of New Target Areas: This program targets
new prospective areas—including Silencio, Neblina, and
Piedralisa—where initial soil anomalies indicate promising
mineralization. Extensive groundwork is underway to refine these
areas for potential discoveries.
- Strategic Growth Based on Comprehensive Analysis: This
14,000-metre program builds on two years of extensive groundwork,
including re-logging, geological modelling, geophysical analysis,
and geochemistry of soils and rocks. Designed to address key
questions around Mocoa's potential, the program reflects a
systematic approach to understanding and expanding the resource's
scale.
"This program, adding 50% more drilling than all previous work
at Mocoa, is a major step forward for the project," said
Ian Harris, President and CEO. "This
achievement reflects the dedication of our team working
hand-in-hand with local partners and the backing of Frank Giustra's Fiore Group. Together, we're
advancing Mocoa at the scale and with the care it deserves."

Harris, President & CEO about the ongoing 14,000 metre
exploration program.
14,000-metre Drill Plan
The 14,000-metre drill program at the Mocoa project (see Table
1) is designed to refine the understanding of high-grade copper and
molybdenum distribution while potentially expanding the resource
through targeted infill and step-out drilling. This comprehensive
program not only aims to deepen insights into the deposit's
high-grade cores but also extends to newly identified areas with
significant resource potential, such as Piedralisa and Neblina.
In parallel, the program will follow up on Cu-Mo-Zn-Pb soil
anomalies at Silencio, Neblina, and Piedralisa. These high-priority
targets were identified through extensive fieldwork and recent
airborne geophysical surveys, underscoring the potential for
additional mineralization outside the known deposit area. (refer to
the new releases May 03, 2022,
November 15, 2022 and February 7, 2023).
This multi-purpose exploration strategy integrates drilling on
the back of extensive geologic, geophysical, and geochemical
groundwork, reflecting Libero
Copper's commitment to advancing Mocoa as a premier copper
asset.
Expansion of the Mocoa system
Libero Copper is advancing its
resource expansion activities at the Mocoa porphyry Cu-Mo deposit,
as previously announced (refer to the news release October 16, 2024). The team has planned
approximately 14,000 metres of drilling (see Figure 1) to confirm
the extension of high-grade cores and to explore potential areas
for resource expansion. This plan relies on the update of the
geological model for alteration and lithologies based on the
detailed relogging of 8,126 metres of drilling conducted between
2008 and 2022, alongside extensive fieldwork and airborne (refer to
new releases May 03,
2022, November 15,
2022 and February 7,
2023).
At Mocoa, 25,198 metres of drilling have been completed along a
north-south strike length of over 1,000 metres, spanning a
west-east distance of 600 metres, and reaching a depth of 900
metres. This historical drilling has intercepted high-grade copper
and molybdenum cores, though with wide drill spacing. The in-fill
drilling (see Table 1) is designed to refine the understanding the
Cu and Mo grade distribution in areas of wide-space drilling, and
to test the deeper sections of the porphyry system below the
existing pit-constrained initial Inferred mineral resource
estimate1 at Mocoa. A detailed review of
available drill cores and the interpretation of high-grade Cu-Mo
distribution indicate that the Mocoa deposit remains open for
potential expansion in all directions. The proposed drill holes are
strategically targeted to extend and confirm historically
identified high-grade zones.
Step-out drilling (table 1) is planned to strategically extend
the overall mineral resource of the Mocoa project to the north and
northeast, aligning with the identified plunge of the high-grade
cores. This targeted drilling approach aims to explore and define
additional mineralization that may exist beyond the current
resource boundaries, offering the potential to increase the size
and grade of the Mocoa deposit.
Additionally, existing drill pads will be utilized to minimize
surface disturbance and preserve the surrounding environment. This
approach not only reduces the environmental impact of drilling
operations but also streamlines the logistical aspects of the
drilling program. Furthermore, the project has implemented a
comprehensive rainwater collection system that secures water use
for drilling, consumption, and sanitation purposes. This innovative
system eliminates dependence on external water sources, enhancing
the sustainability of the operation while ensuring a reliable
supply of water throughout the drilling process. By integrating
these practices, the project demonstrates a commitment to
environmental stewardship and resource efficiency.

MD-044 Update
Hole MD-044 is the first hole in the 14,000-metre drill program
at the Mocoa deposit. As of November 5,
2024, the hole has reached a depth of 615 metres, advancing
toward its target depth of 1,200 metres. The hole was designed to
test the continuity of high-grade mineralization plunging to the
northeast of the deposit, extending below the existing
pit-constrained inferred resource estimate
estimate1 (refer to news release October 16, 2024).
Detailed Anaconda logging reveals that argillic alteration and
iron oxides (after D-type veinlets) dominate the initial 100
metres, with sericite present throughout, overprinting earlier
potassic alteration characterized by A-type (truncated) and
potassium feldspar (K-feldspar) veinlets. Late D-type veinlets,
partially or completely altered to iron oxides, are frequently
observed within this interval. Copper mineralization appears as
quartz veinlets containing chalcopyrite, chalcocite, and minor
bornite, while molybdenum mineralization is present as molybdenite
within B-type veinlets cross-cutting the earlier A-type and K-spar
veinlets.
Surface Exploration
Exploration work completed up to date (refer to new releases
May 03, 2022, November 15, 2022 and February 7, 2023) shows four highly prospective
areas close to the Mocoa Cu-Mo porphyry deposit. Surface
exploration planned for the 2024-2025 season is designed to
follow-up the Neblina, Piedralisa and Silencio areas (figure 2).
200 metres x 50 metres spacing soil grid is planned to fully cover
the Silencio zone and the northwestern sector of Neblina area.
Additionally, comprehensive Anaconda mapping of the main creeks in
these target areas is planned.
- Neblina zone (formerly target 8 and 6) is a prospective area
located to the north-northeast of Mocoa deposits. This area has two
zones of prospection interest named: west and east Neblina
respectively. Neblina West is located 2km to the north of Mocoa
deposit and is associated with a 3D radial symmetric isosurface
intrusion (interpreted as porphyries bodies), analytical signal
magnetics (AS) highs and demagnetized zone. Neblina East is located
3km to the northeast of Mocoa deposit and is associated with a 3D
radial symmetric isosurface intrusion (interpreted as porphyries
bodies) with locally elevated Mo rock values.
- Piedralisa zone (formerly target 5) is a priority target,
located 3km to the southeast of the Mocoa deposit, where previously
was identified and mapped leached cap outcrops consistent with
leached cap related to the upper portion of the Mocoa deposit
(refer to news release February 7,
2023). Furthermore, Piedralisa zone is associated 3D radial
symmetric isosurface intrusion (porphyry) with large 2,500 metres x
1,500 metres Zn-Pb±Cu soil anomaly and elevated Cu-Mo values in
rock samples (refer to the new releases May
03, 2022, November 15, 2022
and February 7, 2023).
- Silencio (formerly target 7) zone is located 3km to the north
of the Mocoa deposit and is related to AS highs, 3D radial
symmetric isosurface intrusions (interpreted as porphyries bodies)
with moderate K-alteration index and locally elevated Cu values.
200 metres x 50-metre space soil grid is planned to cover this area
to extend the Cu soil anomaly previously identified (refer to the
news release February 7, 2023).

prices of Cu - US$3.00/lb, Mo -
US$10.00/lb. Metal recoveries
utilized for the resource model are 90% for Cu and 75% for Mo.
Mineralized zones at Mocoa are bulk porphyry-style zones and
drilled widths are interpreted to be very close to true widths.
Libero Copper operates according
to a rigorous Quality Assurance and Quality Control (QA/QC)
protocol consistent with industry best practices. Primary sample
collection involves secure transport from Libero Copper's core logging facilities in
Mocoa, Colombia to the ActLabs
certified sample preparation facility in Medellin, Colombia. Samples are processed in
the Medellin facilities where they
are analyzed for copper and molybdenum by 4-Acid digest AA
analysis. The sample pulps are air freighted from Medellin to the ActLabs certified laboratory
in Guadalajara, Mexico, where they
are analyzed using 4-Acid digest ICP multi element analysis. In
order to monitor the ongoing quality of assay data and the
database, Libero Copper has
implemented QA/QC protocols which include standard sampling
methodologies, the insertion of certified standard materials,
blanks and field duplicates and ongoing monitoring of data entry,
QA/QC reporting and data validation. No material QA/QC issues have
been identified with respect to sample collection, security and
assaying.
About the Mocoa Porphyry Copper-Molybdenum
Deposit
The Mocoa deposit is located in the department of Putumayo, 10
kilometres from the town of Mocoa. Libero
Copper's district scale holdings cover over 1,000 km2
through titles and applications, encompassing most of the Jurassic
porphyry belt in southern Colombia. Mocoa was discovered in 1973 when
the United Nations and the Colombian government conducted a
regional stream sediment geochemical survey. Between 1978 and 1983,
an exploration program was carried out that consisted of geological
mapping, surface sampling, ground geophysics (IP, magnetics), 31
diamond drill holes totaling 18,321 metres and metallurgical test
work B2Gold subsequently executed diamond drill programs in 2008
and 2012. Libero Copper drilled
Mocoa in 2022 and intercepted notable results of 0.58% CuEq* (0.42%
Cu and 0.047% Mo) over 1,228.5 metres, including a higher-grade
interval of 840.3 metres at 0.72% CuEq* (0.52% Cu and 0.062% Mo)
(see the news release April 26,
2022).
The Mocoa deposit appears to be open in both directions along
strike and at depth. Current work on the property has identified
additional porphyry targets including the possible expansion of
known mineralization. The Mocoa deposit is situated in the Central
Cordillera of Colombia, a
30-kilometre-wide tectonic belt underlain by volcano-sedimentary,
sedimentary and intrusive rocks that range in age from
Triassic-Jurassic to Quaternary and by remnants of Paleozoic
metasediments and metamorphic rocks of Precambrian age. This belt
hosts several other porphyry-copper deposits in Ecuador, such as Mirador, San Carlos, Panantza and Solaris' Warintza.
Copper-molybdenum mineralization is associated with dacite porphyry
intrusions of the Middle Jurassic age that are emplaced into
andesitic and dacitic volcanics. The Mocoa porphyry system exhibits
a classical zonal pattern of hydrothermal alteration and
mineralization, with a deeper central core of potassic alteration
overlain by sericitization and surrounded by propylitization.
Mineralization consists of disseminated chalcopyrite, molybdenite
and local bornite and chalcocite associated with multiphase veins,
stockwork and hydrothermal breccias. The Mocoa deposit is roughly
cylindrical, with a 600-metre diameter. High-grade
copper-molybdenum mineralization continues to depths in excess of
1,000 metres.
