/CNW/ -
Libero Copper
& Gold Corporation
(TSXV: LBC) (OTCQB: LBCMF) (FRA: 29H) ("
Libero Copper
" or the
"
Company
") is pleased to announce that hole MD-046 is underway. It is the third hole of its 14,000-metre resource expansion drilling program at the Mocoa
porphyry copper-molybdenum deposit in Putumayo,
Colombia
.
Highlights
Building on the results from holes MD-043
(refer to news released dated
April 26, 2022
)
, MD-044
(refer to news release dated
January 6, 2025
)
and MD-
045 (
refer to new release dated
February 26, 2025
)
, hole MD-046 is strategically designed as a step-out drill hole to test mineralization beyond previously
drilled areas. This hole is part of
Libero Copper's
ongoing resource expansion program at the Mocoa deposit.
MD-046 is designed to evaluate the continuity of copper and molybdenum mineralization within areas previously modeled as "waste" in the current pit-
constrained resource. This step-out hole is built off the strong results of MD-044 and will test mineralized extensions beyond previous drilling, including
Mc08DH037 (2008) and MC12DH041A (2021).
"Our team is excited to move eastward with MD
–
046, building confidence built off MD-044. This step-out hole is a direct response to the consistent zones
we've encountered, and it exemplifies our commitment to methodically expand Mocoa's footprint,"
stated
Ian Harris President
& CEO,
each new metre drilled
reaffirms Mocoa's standing as one of
Colombia's
most significant copper-molybdenum systems."
Hole MD-046
Libero Copper
continues to advance its 14,000-metre resource expansion drilling program at the Mocoa porphyry deposit with the start of hole MD-046, the third
hole of the campaign and a key step-out to the east. As of
March 12, 2025
, MD-046 has reached a depth of 650 metres and is currently advancing beyond this
point. MD-046 is strategically designed to extend mineralization beyond previously drilled areas (figure 1) and assess the continuity of the deposit within the pit-
constrained resource model. Positioned at an azimuth of 40 degrees with a -65-degree dip, this step-out hole targets areas at depth and laterally, including zones
previously modeled as waste. It is the first hole designed to drilled test the copper and molybdenum grades in the East valley (figure 2).

This eastern expansion is a critical component of
Libero Copper's
resource growth strategy, aiming to unlock additional copper-molybdenum potential and further
define the scale of the Mocoa deposit. Results from MD-046, along with recent released results from holes MD-044
(refer to news release dated
January 6, 2025
)
and MD-045 (
refer to new release dated
February 26, 2025
)
, will contribute to defining the scale and continuity of
the Mocoa porphyry deposit.

The first 90 meters of MD-046 intersected a strongly argillized dacite porphyry with multiple generations of D-veinlets, locally altered to iron oxides. Below this
depth, the hole intercepted an early potassic-altered (K-feldspar) porphyry, hosting well-developed A-type veinlets and disseminated chalcopyrite and molybdenite
mineralization. As drilling continues, MD-046 is advancing through an intermineral porphyry unit, locally brecciated, exhibiting strong sericite alteration. This unit
contains multiple C-type (chalcopyrite-dominant) veinlets cross-cutting earlier B-type (molybdenite-dominant) veinlets, indicating a prolonged and complex
mineralizing event. MD-046 is advancing beyond the conceptual resource pit depth and continues to intersect mineralization, with visible chalcopyrite and
molybdenite. This is particularly significant as MD-046 represents the first step-out to the East into areas previously modeled as waste.

Libero Copper
, is the designated Qualified Person within the meaning of National Instrument 43-101 and has

*Copper equivalent (CuEq) for drill hole interceptions is calculated as: CuEq (%) = Cu (%) + 4.2 × Mo (%), utilizing metal prices of Cu -
US$4.00
/lb, Mo -
US$20.00
/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. Core diameter is
a mix of HQ and NQ depending on the depth of the drill hole. Diamond drill core boxes were photographed, sawed, sampled and tagged in maximum 2-metre
intervals, stopping in geological boundaries. Samples were bagged, tagged and packaged for shipment by truck from
Libero Copper's
core logging facilities in
Mocoa,
Colombia
to the Actlabs certified sample preparation facility in
Medellin, Colombia
. ActLabs is an accredited laboratory independent of the Company.
Samples are processed in the
Medellin
facilities where they are analyzed for copper and molybdenum by 4-Acid digest Atomic Absorption (AA) analysis. The
sample pulps are air freighted from
Medellin
to the ActLabs certified laboratory in
Guadalajara, Mexico
, where they are analyzed for a suite of 57 elements using
4-Acid digest and ICP-MS. 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 copper and molybdenum standard materials, blanks, duplicates (field, preparation and analysis)
randomly inserted into the sampling sequence. QA/QC program also include the 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
km
2
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.
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.
