Panoro Minerals Intersects 260 m at 0.90% Cueq, Cotabambas Project, Peru

VANCOUVER, Aug. 31, 2022 - Panoro Minerals Ltd. (TSXV: PML) (Lima: PML) (Frankfurt: PZM) (OTCQB: POROF) ("Panoro", the "Company") is pleased to announce results of four additional drill holes from its 16,970 m drill program, the aim of which is to expand the high-grade resource and upgrade inferred to indicated resources at the Company's Cotabambas Cu/Au/Ag Project in southern Peru.

Hole CB-198 confirms the high-grade continuity between the previous holes CB-23 and CB-195, intersecting a 260 m length of primary copper sulfide mineralization averaging 0.43% Cu, 0.61 g/t Au and 2.72 g/t, Ag (0.90% Cueq), related to a porphyry stock of quartz monzonite composition intruding the diorite host rock, Figure 1. The intersection includes 130.4 m averaging 0.58% Cu, 0.95 g/t Au and 3.41 g/t, Ag (1.31 % Cueq)

"Drillhole CB-198 delineates the high-grade core contained within the South Pit to approximately 350 m depth, to the bottom of the pit shell defined in the PEA mine plan and indicates continuity to a depth of over 500m to the pit shell constraining the global resource. The high-grade continuity indicates the potential to replace lower grade resource within the mine plan with higher grades including in the early part of the mine plan. This will result in important upsides to the prefeasibility study.", stated Luquman Shaheen, President & CEO.

The purpose of Holes CB-197 and CB-199 was to confirm the east and west continuity of the Copper-Gold high-grades near the surface, respectively and the purpose of holes CB-198 and CB-200 was to confirm the lateral and vertical continuity. See the locations of the holes on the map Figure 2. The most significant results are listed in the table below.

Drill hole CB-197 explored the easter continuity of the new high grade intersected by the previously announced hole CB-196, located 150m to the west. The hypogene mineralization was intersected in five splits with copper and gold anomalies. The mineralization is contained within the diorite host rock printed with an overlapping of potassic, SCC and phyllic alterations. The intersections show intensive faulting suggesting the high-grade mineral block was moved to depth and northwest, in direction to the North pit.

Drillhole CB-198 explored the high-grade continuity in section 5W, intersecting copper primary mineralization along 260.0 m averaging 0.43%Cu, 0.61 g/t Au and 2.72 g/t Ag (0.90% Cueq) including 130.4 m grading 0.58% Cu, 0.95 g/t Au and 3.41 g/t Ag (1.31 % Cueq) underlain by 53.9 m averaging 0.40% Cu, 0.37 g/t Ag and 2.83 g/t Ag (0.70 % Cueq). The quartz monzonite porphyry with potassic and SCC alterations is hosting a wide stockwork of quartz veinlets with chalcopyrite, pyrite and magnetite. The three holes completed in this section confirm a vertical continuity of the high grade of 350 m, with grades varying between 0.67% and 0.92% Cueq. and widths between 180 and 260m.

Drillhole CB-199 is located 150 m to the east of the high grade intersected by drillholes CB-195 and CB198, and 100 m above the mineralization intersected by drillhole CB-20, Figure 2. The hole intersected a fault system constraining the lateral mineral continuity, intersecting two copper anomalies hosted in the diorite with moderated potassic alteration.

Drillhole CB-200 located 100 m above CB-196, where the high-grade was intersected. CB-200 intersected almost 50 m of primary copper mineralization averaging 0.31% Cu, 0.27 g/t Au, 2.14 g/t Ag (0.53 Cueq %). The interval is part of an extensive hypogene mineralization developed in the hanging wall of a quartz monzonite porphyry not intersected by drillhole CB-196, suggesting blocks have been moved by local faulting.

Exploration Model at the South Pit

Six holes have been completed in the South pit in for a total of 16 holes (6,166m). A porphyry of quartz monzonite composition (QMP2) is emplaced along a structural control in an almost North-South direction into the diorite host rock, and subsequent intrusions of narrow dikes of QMP3, quarciferous/dacite, monzonite and latite compositions. A second faulting system in North 60-80 East direction intersects the porphyry at its north extreme, where other porphyry stages intrude (the QMP1) and enrich the metal concentration. Finally, a lithocap of andesite volcanic hides the previous lithologies and mineralization under the surface, following an overthrust faulting in a west direction.

The alteration model is centered by the potassic assemblage in the QMP1, expanding to the QMP2 and the diorite host rocks, following mainly the North 60-80 East structural direction. The SCC alteration assemblage is proximal to the potassic, with the phyllic and propylitic alterations appearing outwards of the porphyry center. See a typical section in Figure 1.

The drilling results confirm the existence of a high-grade ore body (HGOB) centered by the QMP1, extending along the N60-80E structural control, and dipping to the south-southeast. The hypogene sulfide in this body is intimately associated with multiphase stockworks and unidirectional arrays of millimetric and centimetric veinlets of A, B, and M types, in potassically altered rock of the QMP1 and adjacent diorite. The copper-gold mineralization in the HGOB is dominantly contained in a steeply inclined, tabular zone of intense quartz veining, typically carrying >30 veinlets per meter. The HGOB widths vary from 50 m to 260 m and averaging grades from 0.51 to 1.21 % Cueq. The ore body outcrops at surface along 150 m strike length and shows a vertical continuity to over 450m depth, where its lateral footprint is increased to 450m along strike. Good potential exists to grow the lateral continuity to 750 m along strike, as suggested by the drillhole, CB-05, located close to the North pit limit. See Figure 3, Figure 4, Figure 5 and Figure 6.

The average copper:gold ratio, in term of contained metal value, in the South pit is 1:1 and reflects the higher gold content than in the North pit where this ratio is averaging 2.7:1. The silver:gold ratio in the South Pit is 6:1 while in the North pit this increases up to 14:1. The South pit is interpreted as an early and different mineral pulse of Cu-Ag mineralization rich in gold, as suggested by geochronology studies. The secondary biotite of the potassic alteration in the South pit porphyry reports an Ar-Ar age of 35.3+0.7 Ma, while in its pair of the North pit reports an Ar-Ar age of 35.9+0.4 Ma (R. Rivera 2011). Another study confirmed with K-Ar methods an age of 35.7+0.9 Ma for the North pit porphyry and 43.2+1.1 Ma for the diorite host rock (K-Ar age by Perello et.al. 2003).

The geophysics signatures also build up an exploration model that may guide future drilling of the potential at depth. The HGOB is open and deepening to join the west side of an isolated high resistivity signature, wrapped and surrounded by a high magnetic anomaly. The chargeability is split into two blocks and interpreted as an external pyrite halo following a structural over-thrusting, through which the HGOB is deepening, as shown in Figure 7.

Finally, the bottom of the PEA South pit is located between 230 and 300 m below the surface and shows the high potential to incorporate new mineral resources at depth, along strike and at depth following the structurally controlled porphyry.

The Company continues drilling in the South pit adding new mineral resources and upgrading inferred to the indicated category. In parallel, the re-logging and updates of the geologic modelling are progressing in parallel. Some of the future drillholes will be located below the CB-23 (section 5W), CB-63 (section 4W) and CB-196 (section 3W).

Summary of Cotabambas Project PEA Results

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.
