The principal conclusions from the drill results are summarized
as follows, see Figures 1 and 2 for drillhole locations:
- Drillhole CB-204 intersected 317.5 m of hypogene copper mineralization grading
0.56% Cueq below the current limits of the South Pit, including
113 m of a porphyry stock, with
95.0 m grading 0.44% Cu, 0.45 g/t Au,
3.13 g/t Ag (0.83% Cueq) and 44.0 m
averaging 0.38% Cu, 0.38 g/t Au, 2.71 g/t Ag (0.71% Cueq)
- Drillhole CB-205 at the North Pit was terminated at
a shallow depth of 122.9 m due to
water flow from the drillhole, the drillhole intersected
79.2 m averaging 0.65% Cu, 0.44 g/t
Au, 5.19 g/t Ag (1.05% Cueq) of hypogene copper mineralization, the
hole will be recollared and drilled to the east
- Drillhole CB-206 delineated the extension of the
high-grade zone to near surface at the west side of the North Pit,
intersecting 341.7 m of primary
copper sulphides averaging 0.56% Cu, 0.40 g/t Au, 2.75 g/t Ag,
(0.91% Cueq) related to multiple porphyry dikes, including
115.6 m averaging 2.02% Cueq and
68.6 m with 2.93% Cueq
- Drillhole CB-207 results delineate 290.2 m of hypogene copper mineralization in the
North Pit averaging 0.55% Cueq, including intervals of 153.6 m grading 0.69% Cueq, 89.7 m averaging 1.01% Cueq and 35.7m grading 1.50% Cueq, centered on a porphyry
stock exposed in this section with 87
m width
- Drillhole CB-208 intersected 404.0 m of hypogene copper mineralization below
the existing limits of the South Pit, averaging 0.48% Cueq,
including intervals of 66.5 m grading
0.44% Cu, 0.54 g/t Au, 3.68 g/t Ag (0.91% Cueq), and 122.8 m averaging 0.37% Cu, 0.27 g/t Au, 2.42 g/t
Ag (0.61% Cueq), hosted in a porphyry stock of 321 m width of quartz monzonite composition, that
still open at depth.
Luquman Shaheen, CEO of Panoro Minerals states, "The drill
results continue to fortify the potential for increasing the size
of the high-grade zone at both the North and South Pit. The
drilling indicates continuity at depth to below the limits of the
pit shells while local structure controls and correlation to
geophysics results are serving as a good tool to trace the
mineralization along strike. Mineralization intercepts from
100 m to over 300 m with grades ranging from 0.91% Cueq to
2.02% Cueq reflect well on the high-grade potential. The
high-grade zone at the south pit is now traced to over 550 depth,
well below the PEA pit shell and the porphyry is increasing
significantly in thickness with depth. We look forward to
announcing additional results as they are received and
analyzed."
DISCUSSION OF RESULTS
The purpose of Holes CB-205, CB-206 and CB-207 was to infill the
area of high grade inferred resources targeting and upgrade to
indicated category in the high-grade zone located in the south area
of the North Pit. The continuity of this high-grade zone
remains open at depth and along strike to the south (see Figure
1).
The goal of the CB-204 and CB-208 was to step out the high-grade
Cu-Au mineralization to the south, south-east and at depth at the
South Pit. Each hole was stepped out approximately
100m from previous drillholes
targeting the addition of indicated resources (see Figure
2).
The more significant mineralization intercepts from the five
drillholes are summarized in the table below.

SOUTH PEA PIT
Drillhole CB-204 delineates the continuity of the
high-grade zone to a depth of 200 m
to 400 m below the high-grade zone
intercepted CB-198 previously announced in the section 5W and to
below the limits of the PEA South Pit. After crossing the diorite
and andesite in the hanging wall, the drillhole intersected from
depths of 277.8 m to 595.3 m the hypogene copper mineralization, or
317.5 m averaging 0.30% Cu, 0.30 g/t
Au, 2.31 g/t Ag (0.56% Cueq), including two intervals of
95.0 m grading 0.44% Cu, 0.45 g/t Au,
3.13 g/t Ag (0.83% Cueq.) and 44.0 m
averaging 0.38% Cu, 0.38 g/t Au, 2.71 g/t Ag (0.71% Cueq). The
quartz stockwork containing chalcopyrite with minor pyrite is
centered by a porphyry stock of 113 m
width, developing the mineralization to the hanging and foot walls,
with potassic alteration, and composed of orthoclase, secondary
biotite, chlorite, and magnetite assembly. See cross section in
Figure 3.
Drillhole CB-208 delineated mineralization at the PEA
life of mine average grade, some 100
m to 300 m below the CB-63 and
below the PEA pit limits and also 100
m to the northeast of CB-204, in the section 4W. This hole
identified 321 m of the porphyry
stock of quart monzonite composition intruding the diorite host
rock, intersecting 404.0 m averaging
0.27% Cu. 0.24 g/t Au, 2.20 g/t Ag (0.48% Cueq), of which almost
95% is hosted in the porphyry stock. The intersection includes two
intervals of 66.5 m grading 0.44% Cu,
0.54 g/t Au, 3.68 g/t Ag (0.91% Cueq), and 122.8 m averaging 0.37% Cu, 0.27 g/t Au, 2.42 g/t
Ag (0.61% Cueq), both located inside the porphyry stock domain. The
hole was terminated in the porphyry domain, so the limits of the
stock still undefined. See cross section in Figure 4.
The drillholes CB-204 and CB-208 are defining the continuity of
the high grade zone to over 550 m
depth to below the PEA pit limit and extending to the current
resources pit-shell. The results confirm a plunge of the high grade
and the principal porphyry in south-southeast direction, where the
drilling exploration is still in progress.
NORTH PEA PIT
Drillhole CB-205 was terminated at a depth of
122.9 m due to water flow. The
drillhole was recollared to the east, CB-214, where the target
mineralization was recently crossed and assaying is in progress.
CB-205 intersected 42 m of the
porphyry stock hosting and expanding to the hanging wall containing
79.2 m of primary copper sulphide
grading 0.65% Cu, 0.44 g/t Au, 5.19 g/t Ag (1.05% Cueq) including,
inside the porphyry, 45.3 m averaging 0.90% Cu, 0.57 g/t Au,
5.46 g/t Ag (1.41%Cueq). See the cross section in Figure
5.
Drillhole CB-206 located 200m to the northwest of the drillhole CB-205, at
the same cross section 8E. This infill hole provides better
definition of the high-grade distribution to the west side of the
North Pit, intersecting 342m length
of primary copper sulphide averaging 0.56% Cu, 0.40 g/t Au, 2.75
g/t Ag, (0.91% Cueq) related to a swarm of porphyry dikes of quartz
monzonite composition intruding the diorite host rock. The
intersection includes 42.6 m of
copper oxides and mixed mineralization averaging 0.63% Cu, 0.63 g/t
Au, 4.94 g/t Ag (1.18% Cueq), underlain by 221.5 m of primary copper sulphides grading 0.71%
Cu, 0.49 g/t Au, 2.97 g/t Ag (1.13% Cueq) including two intervals
of 115.6 m averaging 1.25% Cu, 0.90
g/t Au, 5.03 g/t Ag (2.02% Cueq) and 68.6
m grading 1.80% Cu, 1.32 g/t Au, 6.93 g/t Ag (2.93% Cueq).
See the cross section in Figure 5.
Drillhole CB-207, an infill drillhole located
100 m to the northeast of the hole
CB-205. The hole delineated copper mineralization 450 m below the surface in the North Pit. The
results from CB-207 delineate 290.2 m
of mixed and hypogene copper averaging 0.34% Cu, 0.23 g/t Au, 2.97
g/t Ag (0.55% Cueq) including intervals of 153.6 m of primary copper sulphides grading 0.39%
Cu, 0.33 g/t Au, 3.18 g/t Ag (0.69% Cueq), including 35.7 m averaging 0.79% Cu, 0.82 g/t Au and 4.88
g/t Ag (1.50% Cueq), overall centered by a porphyry stock exposed
with 87m width in the section 9E. See
cross section in Figure 6.
EXPLORATION MODEL
In the North and South pits the high-grades of Cu-Au
intersections are typically centered by the quartz-monzonite
porphyry in contact with the diorite host rock and following the
local structural controls striking north-northeast to north-south,
over an area of approximately 3 km by 1.8 km. The
mineralization is composed of a swarm of porphyry dikes typically
when the porphyry stock is nearby or below, as shown by some
drillholes along the cross sections.
The drilling at the South Pit is confirming the geophysics
signatures delineating the north and south extensions of the
mineralization. A preferential plunge of the hypogene
mineralization is observed and controlled by staggered
gravitational faulting.
The Company continues with the infill drilling program in the
North Pit and the step out drilling program in the South Pit, to
incorporate new high grade mineral resources and upgrade inferred
resources to indicated category. In parallel, the re-logging of
drillholes and updates of the geologic modelling are progressing
towards a more robust revision of the exploration model. The
drilling campaign started in April
2022 and to date has accumulated over 10,000 m of a plan of the planned 16,970 m, distributed in 4,731 m in the North Pit and 5,300 m in the South Pit.
Finally, Panoro is preparing a group of platforms for start the
exploration drilling in a Cu-Au Skarn target located near to North
Pit.
SOCIAL ENGAGEMENT
Also, Panoro is pleased to announce our Christmas celebrations
in the communities of Cochapata, Ccalla, Ccarancca, Guaclle and in
the Cotabambas district with the schoolchildren of Santa Rita, San Martin, Angelitos de Jesus and
Cunamas Schools. Panoro continues to advance social programs in
harmony with the local communities. The company will
remobilize the drilling program in early January following the
cessation for the Christmas and New Year's break.
