VANCOUVER, BC, June 7, 2022
/CNW/ - Panoro Minerals Ltd. (TSXV: PML) (Lima: PML)
(Frankfurt: PZM) (OTCQB: POROF) ("Panoro", the "Company") is
pleased to provide an update of its exploration drill program at
its 100% owned Cotabambas Cu/Au/Ag Project in Peru.
Drillhole CB-195, the first hole completed of the 2022 program,
intersected 195.8m averaging 0.55%
Cu, 0.52 Au g/t, 2.88 Ag g/t (0.92% Cueq), including a profile of
copper oxides, mixed and hypogene zones. The primary copper
sulfides in the hypogene zone include 45.7m grading 0.95% Cu, 0.78 g/t Au and 4.35 g/t
Au (1.51% Cueq) into a porphyry stock of quartz monzonite
composition.
The drill program commenced with the mobilization of the first
drill rig during the last week of April
2022 at the South Pit area. The drill core was logged and
sampled on site and samples were prepared and analyzed at ALS
Chemex Laboratories in Lima.
The South Pit Area
The South Pit target is located between 400m to 1200m to
the south of the proposed North Pit as defined by the September 22, 2015 Preliminary Economic
Assessment. The Hole CB-195 tested the mineralized area located
between previous Drillholes CB-23 and CB-34, see link1, and was
completed to a total depth of 240.2m.
The following table details the more significant intersections.

Luquman Shaheen, President & CEO, of Panoro Minerals states,
"The results of drillhole CB-195 validate Panoro's thesis that
there exists potential to grow the high-grade component of the
Cotabambas Project resource. The high grades have been
intersected near surface with the potential to provide additional
high grade to the mine plan early in the proposed mine-life.
Furthermore, the intersection of the high grades in CB-195 at the
South Pit also indicate the potential to extend the high grade
intersects along strike from the South Pit to the North Pit and to
the north of the North Pit, see link 2. Step out and infill
drilling is planned in these areas as part of the on-going
exploration program. The exploration program will continue to
the end of the year with an estimated 16,000
m of exploration drilling to be completed. We look
forward to announcing results from drill hole assays as they are
received and analyzed."
See link 3 for cross section at drill hole location. The
hole commenced within a barren lithocap leach capping of volcanic
andesite package and diorite intrusive from surface to 35 m, including supergene argillic alteration and
traces of copper and manganese oxides.
From 35.0m to 75.5m the hole intersected phyllic and
potassically altered quartz monzonite with copper oxide grading
0.40% Cu, 0.37 g/t Au, 2.77 g/t Ag (0.67% Cueq). The copper oxides
species are chrysocolla, malachite, tenorite, neotocite and iron
oxides.
From 75.5m to 95.0 m the drill hole intersected potassic
interleaved with sericite, chlorite, clay (SCC) alterations in the
quartz monzonite porphyry hosting a copper mixed zone of
19.5m width averaging 1.01% Cu, 1.15
g/t Au, 5.18 g/t Ag (1.83% Cueq). The mineralogic species are a mix
of chrysocolla, tenorite, neotocite, chalcopyrite and pyrite into a
framework of quartz veinlets.
Finally, from 95.0m to
230.8m over the quartz monzonite
porphyry with potassic/SCC alteration with primary chalcopyrite
mineralization of 135.8m width
grading 0.53% Cu, 0.48 g/t Au and 2.59 g/t Ag (0.88% Cueq), before
re-entering the diorite intrusive host rock. A more strongly
mineralized, silicified and potassically altered interval with
disseminations and veinlets of chalcopyrite graded 0.95 % Cu, 0.78
g/t Au and 4.35 g/t Ag (1.51% Cueq) over 45.7 meters from
95.0 m to 140.7m.
Drilling has shown that the extensive chalcopyrite
mineralization and potassic alteration in the porphyry "center" is
surrounded by "proximal" SCC alteration with pyrite>chalcopyrite
sulfides and "distal" propylic alteration with disseminated pyrite
mineralization into the diorite host rock. The gold and silver
values occur overall this lateral zoning and randomly emplaced with
the SCC and potassic alteration event.
Most of the high grade intersected by this hole will represent
new resources to be added in the block model of the 2015 PEA
pit.
Additional drilling continues to test this mineralization to the
northeast with the step out hole CB-196, which assays results are
in progress and published in a next press release.
About Panoro
Panoro is a uniquely positioned Peru-focused copper development company. The
Company is advancing its flagship Cotabambas Copper-Gold-Silver
Project located in the strategically important area of southern
Peru.
The Company's objective is to complete a Prefeasibility study in
2023 with work programs commencing in Q1 2022.
At the Cotabambas Project, the Company will first focus on
delineating resource growth potential and optimizing metallurgical
recoveries. These objectives are expected to further enhance the
project economics as part of the Prefeasibility studies during 2022
and 2023. Exploration and step-out drilling from 2017, 2018
and 2019 have already identified the potential for both oxide and
sulphide resource growth.

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.
