NEWS RELEASE
Luca intersects 136 metres of 1.6 g/t Gold, 77 g/t Silver, 0.9% copper and
1.6% zinc at largo Norte Zone, Campo Morado Mine
Vancouver, B.C., February 17, 2026: Luca Mining Corp. (“Luca” or the “Company”) (TSX-V: LUCA; OTCQX:
LUCMF; Frankfurt: Z68) is pleased to announce new underground drill results from its ongoing exploration
program at the Campo Morado polymetallic VMS mine in Guerrero State, Mexico.
Highlights
• On-going success defining high-grade, gold and silver- rich VMS mineralization in areas
immediately adjacent to active underground workings at Campo Morado
• Underground drillhole CMUG-25-36 intersected 135.7 metres (“m”) of 1.58 g/t Au, 77.10 g/t Ag,
0.88% Cu, 0.40% Pb and 1.61% Zn from 87.7m, defining new mineralization at an unmined zone
and extending mineralization approximately 20m from the previously defined extents of the Largo
Norte Zone
• Underground drillhole CMUG -25-33 intersected 14.3m of 1.50 g/t Au, 75.81 g/t Ag, 1. 01% Cu,
0.46% Pb and 2.81% Zn from 167.6m, defining new mineralization within the Fish Zone
• Based on the results of CMUG-25-36, follow-up drilling of the Largo Norte Zone has commenced
with a focus on the definition of additional mineral resources
• Drilling is ongoing at Campo Morado with two surface drill rigs and one underground drill rig
Paul D. Gray, Luca’s VP of Exploration, commented:
"The Largo Norte Zone remains largely unmined; CMUG-25-36 targeted an area just west of the existing
bounds of the mineralized body and was designed to expand mineralization in this under-drilled area of
the Campo Morado Mine . This drillhole intersected a long, consistent interval of massive sulphide
mineralization beyond known mineralization extents. The Largo Norte Zone represents a large, consistent
mineralized VMS body that dips shallowly to the south and ranges from 20 to 60 meters in thickness. Based
on the strength of the mineralization intersected in CMUG-25-36, follow-up drilling has been initiated with
a view to further expand mineralization to the west.”
Near-Mine Underground Drilling
Underground drillhole CMUG-25-36 targeted areas immediately adjacent to the previously defined
western extent of the Largo Norte Zone and successfully intersected mineralization from these unmined
areas, including:
• CMUG-25-36:
o 135.7m of 1.58 g/t Au, 77.10 g/t Ag, 0.88% Cu, 0.40% Pb and 1.61% Zn from 87.7m
Including 101.5m of 1.92 g/t Au, 98.59 g/t Ag, 0.88% Cu, 0.5 2% Pb and 2.14% Zn from
121.9m with a high grade section of 16.0m of 3.20 g/t Au, 191.84 g/t Ag, 0.99% Cu, 1.29%
Pb and 5.03% Zn from 207.4m

Underground drillholes CMUG-25-27 and CMUG-25-28 targeted extensions of the C-227 mineralized
zone, both currently under mine development, and successfully intersected mineralization from
unmined areas, including:
3
• CMUG-25-28:
o 6.6m of 0.54 g/t Au, 67.62 g/t Ag, 1.05% Cu, 0.65% Pb and 3.26% Zn, from 261.7m in a
zone located within approximately 40m of existing underground workings
Underground drillholes CMUG-25-29 and CMUG-25-30 targeted extensions of the A8 mineralized zone,
and successfully intersected mineralization from unmined areas, including:
4
• CMUG-25-30:
o 1.5m of 0.46 g/t Au, 36.00 g/t Ag, 1.55% Cu, 0.33% Pb and 2.57% Zn from 151.9m
Underground drillhole CMUG-25-33 targeted extensions of the Fish mineralized zone, and successfully
intersected mineralization from unmined areas, including:
5
• CMUG-25-33:
o 14.3m of 1.50 g/t Au, 75.81 g/t Ag, 1.01% Cu, 0.46% Pb and 2.81% Zn from 167.6m

These recent intersections underscore the multiple opportunities to add additional mineable resources
proximal to current development headings, existing infrastructure and expand previously defined mineral
resources.
Drilling continues at Reforma and El Rey, in conjunction with on-going underground drilling planned to
target the Largo, Largo Norte, Naranjo and Fish deposits, which all contribute to the 2026–2028 mine
plans.

mineralized body which ranges from 20 to 60m in thickness.

About Campo Morado Exploration Program
8
The current Campo Morado drill campaign represents the first meaningful exploration program conducted
on the property since 2014 and is designed to support the addition of mineral resources to the near- and
medium-term mine plan.
To date, 38 underground diamond drillholes totaling 9,043m have been completed at the Campo Morado
mine using “HQ” and/or “NQ” sized diamond drill core. These underground drillholes are focused on the
definition of mineable resources proximal to existing underground workings, as well as testing new zones
interpreted to host extensions of known mineralization based on the property’s extensive historical
drilling database.
In addition, 8,682m have been drilled from 2 9 surface drillholes at the Reforma, El Rey , Reforma Deeps
and Zapata targets using “HQ” and/or “PQ” sized diamond drill core. These surface drillholes are designed
to confirm and expand existing mineral resources at the Reforma and El Rey deposits, collect material for
additional metallurgical test work, and support the potential inclusion of these deposits into an improved
Campo Morado mine plan.
Previous exploration at Campo Morado has generated an extensive, high -quality proprietary geological
database, including more than 600,000 m of underground and surface drilling, property -wide geological
and structural mapping, approximately 30,000 geochemical soil samples, and a range of airborne and
ground-based geophysical surveys, including gravity, magnetics, electromagnetics and induced
polarization. Interpretation of these datasets —particularly gravity surveys —has directly contributed to
the discovery and definition of mineralized zones on the property and will continue to guide future
exploration. Luca is currently compiling, cleaning and reinterpreting this geophysical database to prioritize
the more than 38 exploration targets identified across the Campo Morado concession package.
