VANCOUVER, BC , Nov. 21,
2022 /CNW/ - Panoro Minerals Ltd. (TSXV:
PML) (Lima: PML) (Frankfurt: PZM) (OTCQB: POROF) ("Panoro",
the "Company") is pleased to announce results of additional drill
holes from its 16,970 m drill program, the aim of which is to
expand the total resource with emphasis on the high-grade component
and upgrade the inferred category resources to indicated category
at the Company's Cotabambas Cu/Au/Ag Project in southern
Peru. The principal conclusion
from the results of Drillholes CB-201, CB-202 and CB-203 are
summarized as follows, see Figure 1 for drillhole locations:

- Drillhole CB-201 results delineate the continuity of
mineralization approximately 150 m to
the north of the South Pit in the gap area between the two pits as
well as extending mineralization continuity from approximately
200 m depth to near surface;
- Drillhole CB-202 results delineate the extension to
approximately 250 m depth of
previously intersected mineralization and extends mineralization to
the south of the current South Pit limits. The mineralization is
open at depth with the potential for increasing grades at depth and
proximity to the porphyry stock; and
- Drillhole CB-203 extends mineralization to approximately
500 m depth and extends
mineralization to the eastern limit of the South Pit.
Discussion of Results
The purpose of drillholes CB-202 and CB-203 was to add new
mineral resources to the south-eastern and north-eastern extremes
of the South Pit, respectively and at depth. The scope of CB-201
was to explore the possible connection between the South and North
pits. See locations of the holes on the map in Figure 1. The
principal mineralization intersections are listed in the table
below.

Drillhole CB-201 is a step out hole executed to explore
the western and near surface continuity of the mineralization
previously intersected by CB-05 (106.5
m averaging 0.44% Cueq, including 68.5m averaging 0.62% Cueq). The hole CB-201
intersected 22.9 m of mixed
mineralization grading 0.40% Cueq suggesting the higher grades may
be expanded at depth and below CB-05. The plan is to complete a new
drillhole from platform S-17 to explore the mineral continuity
below CB-05. This battery of drillholes is targeting the expansion
of the mineral resources to join the South and the North Pits. See
Figure 2.
Drillhole CB-202 was a step out hole directed to explore
the high-grade continuity at depth, targeting the area 100 m below the mineralization intersected in
previous hole CB-20. The hole intersected copper primary
mineralization along 237.6 m
averaging 0.25% Cu, 0.20 g/t Au and 1.65 g/t Ag (0.43% Cueq)
including 108.35 m grading 0.36% Cu,
0.31 g/t Au and 2.50 g/t Ag (0.63% Cueq), and including also
52.8 m averaging 0.48% Cu, 0.44 g/t
Ag, 3.50 g/t Ag (0.87% Cueq). The mineralization in both drillholes
is developed into a quartz monzonite dike of 35 m width and extending into the diorite in the
footwall host rock. The potassic alteration is developed also in
both lithologic domains. The primary mineralization is composed of
chalcopyrite and minor pyrite into a pervasive quartz stockwork.
Figure 3 shows the copper and gold grades increasing at
depth. A new step out hole is planned from the platform S-5,
targeting the cupula of the porphyry stock and potential for wide
high-grade zones of mineralization. CB-202 represents the furthest
south drillhole in the South Pit, intersecting new mineralization,
the extension of which will be tested with additional drilling.
Drillhole CB-203 is a step out hole located 100 m to the east of the previously executed
CB-196. and represents the northern most mineralization intersected
in the north extreme of the South Pit. The hole CB-203 intersected
a copper primary mineralization within the diorite host rock from
depths of 112.6 m to 706.4 m, including an interval of almost
190 m averaging 0.29% Cu, 0.23 g/t
Au, 1,72 g/t Ag (0.49% Cueq). The higher copper and gold grades
were intersected within the diorite located near the cupula of the
quartz monzonite porphyry stock and intersected at depth with
chalcopyrite stockwork and potassic alteration. See Figure
4.
The bottom of the PEA South Pit is located between 230 and
300 m below ground surface. Drilling
to date indicated the potential to incorporate new mineral
resources at depth and along strike related with the structurally
controlled porphyry mineralization. The intersections shown in
Figure 2 and Figure 3 extend to the north and southern extremes of
the South Pit. The previously intersected mineralization in the
area was at elevations between 3400 m
and 3500 m whereas CB-203, shown in
Figure 4, intersected mineralization down to elevations of
3100 m. The results are confirming
the interpretations in the current exploration model indicating the
potential to expand the resource at depth and along strike. The
South pit is interpreted as an early and different porphyry pulse
of Cu-Ag mineralization rich in gold, as suggested by geochronology
studies and the lower copper:gold and silver:gold ratios
than in the North pit.
The Company started the 2022 campaign in April and continues
drilling in the South and North pits with three drill rigs,
targeting the addition of new mineral resources and the upgrade of
inferred resources to indicated category. The re-logging for the
geologic modelling update and the expansion of the South pit still
in progress.

PEAs are considered preliminary in nature and include Inferred
Mineral Resources that are considered too speculative to have the
economic considerations applied that would enable classification as
Mineral Reserves. There is no certainty that the conclusions within
the PEAs will be realized. Mineral Resources are not Mineral
Reserves and do not have demonstrated economic viability.
