Discussion
Results in this press release complement the first hole CB-228 previously announced, which encountered over 850 m of continuous mineralization, where the high-grade mineralization was encountered along 487.40 m averaging 0.80% CuEq 2 (0.36% Cu, 0.34 g/t Au and 2.56 g/t Ag) starting at 349.65 m downhole. This broader zone includes 317.65 m length grading 1.04% CuEq 2 (0.46% Cu, 0.45 g/t Au and 3.19 g/t Ag), including 162 m averaging 1.54% CuEq 2 (0.65% Cu, 0.70 g/t Au and 4.24 g/t Ag).
Drillholes CB-229 and CB-230 represent the lateral extensions of the main high-grade component intersected by Drillhole CB-228, between elevations 2900 m and 3200 m.
The cross-section for CB-230 shows the increase in the true width of the mineralization from 150 m at surface (elevation 3700 m) to 600 m at depth (elevation 2700 m), and at CB-229 from 120m (elevation 3600 m) to 300m (elevation 3100 m). It is estimated that the true width will continue expanding until reaching contact with the head of the porphyry stock, where contact with limestone is expected to generate high-grade skarn mineralization.
In the below referenced long section these intersections are shown to extend the footprint of the high-grade component 600 m along strike between the elevations of 2900 m and 3200 m, although Drillhole CB-230 leaves the mineralization open at depth at an elevation of 2600 m. This indicates 1,100 m of vertical continuity of the high-grade component. A next battery of 3 drillholes is exploring the expansion of this footprint 200 m to the north, with CB-232, and at depth with CB-231 and CB-233 (between levels 2500 and 2900 m).
Drill Hole Descriptions
- Drillhole CB-229-26 directed to explore the continuity of the high-grade copper and gold, 200 m to the south of drillhole CB-228 at similar elevation.
At the High-Grade Scale, this hole intersected 69.90 m of primary copper sulfides grading 0.52% CuEq (0.27% Cu, 0.32 g/t Au, 1.83 g/t Ag) in the diorite host rock, characterized by secondary biotite and magnetite, in dissemination and veinlets with quartz veinlets hosting chalcopyrite. Some flows of K-feldspar enriched in orthoclase hosting chalcopyrite were identified with some intervals reporting 1.5m averaging 4.43% CuEq (0.24% Cu and 5.22 g/t Au, 3.77 g/t Ag) and 1.0 m length grading 1.73 % CuEq (1.09% Cu, 0.88 g/t Au and 4.80 g/t Ag).
At a Larger Scale , this hole intercepted 85 m of the Main porphyry stock (QMP2) intruding the diorite host rock with copper sulfide mineralization along 303.3 m averaging 0.14% Cu, 0.13 g/t Au, 1.30 g/t Ag and 0.002% Mo (0.29% CuEq), including 98.9 m averaging 0.26%Cu, 0.27 g/t Au, 1.69 g/t Ag and 0.0013%Mo (0.24% CuEq), which included the high-grade previously mentioned. The Main Porphyry stock is barren and shows mainly SCC alteration, minor potassic and phyllic alterations with few type "A" quartz veinlets with pyrite and lesser chalcopyrite.
The mineralization remains open to the west in this area of the South Pit, to be tested with additional drilling.
- Drillhole CB-230-26 targeted exploration of continuity of the high-grade copper and gold, 200 m to the north of the CB-228 at similar elevation.
At the High-Grade scale, this hole intersected hypogene copper mineralization along 48.1 m length averaging 0.76% CuEq (0.57% Cu, 0.25 g/t Au, 0.25 g/t Au, 4.08 g/t Ag) within a main interval of 156.50 m grading 0.55% CuEq (0.38% Cu, 0.22 g/t Au, 2.95 g/t Ag) . The geologic environment is characterized by narrow dikes of the Principal Porphyry (QMP1) of quartz-monzonite composition intruding the diorite host rock. The hypogene mineralization is composed of type "A" quartz veinlets with chalcopyrite and minor pyrite within an envelop of potassic and SCC alterations.
At Larger Scale, the High-grade intersected is a small part of a Main Porphyry Stock (QMP2) intruding the micro-diorite and diorite host rocks.
The Main Porphyry Stock (QMP2) was intersected along 192.1 m where the hypogene copper mineralization average 0.32% CuEq (0.25% Cu, 0.06 g/t Au, 1.11 g/t Ag), while in the host rock is extended along 616.0 m grading 0.3% CuEq (0.21% Cu, 0.12 g/t Au, 1.66 g/t Ag). The K-feldspar is developed into the porphyry while the secondary biotite, chlorite and magnetite is developed into the host rock domain. The mineralization is represented by Type "A" quartz veinlets with chalcopyrite and minor pyrite and minor Type "B" quartz veinlets with molybdenite, chalcopyrite and pyrite.
Skarn, Endo-Skarn type mineralization was intersected along almost 34 m with hypogene mineralization grading 0.33% CuEq (0.27% Cu, 0.07 g/t Au, 0.99 g/t Ag), into the Porphyry stock domain. The presence of pyroxenes, amorphous andradite garnets, anorthite/albite, chlorite, anhydrite are typical of this environment, where chalcopyrite and pyrite mineralization at up to 0.63 %CuEq (0.56%Cu, 0.13 g/t Au, 2.20 g/t Ag). This represents a significant finding since the ferrobamba carbonate rocks are predicted below the diorite, where the Main and Principal Porphyry (QMP1) may interact to generate a large high-grade zone. Endo-Skarn can be generated only through interaction with limestone and may suggest the proximity of an Exo-Skarn type environment beneath the South Pit, similar to those hosting the copper high-grades in Las Bambas, Antapaccay and Constancia mines and those occurring in other targets at the Cotabambas project, such as Jean Louis, Chaupec, Tamburo, NW pit and SW pit.
The Principal Porphyry (QMP1), this intrusive is typically related to the introduction of high Cu-Au grades in the Cotabambas deposit, the main difference with the QMP2 is the abundant presence of stockwork veinlets and intensive K-feldspar alteration. Drillhole CB-230 terminated in over 39.2 m of QMP1 with hypogene copper mineralization averaging 0.42% CuEq (0.36% Cu, 0.07 g/t Au, 1.06 g/t Ag) with intervals of 1m averaging up to 0.67% Cu, 0.15 g/t Au and 3.0 g/t Ag (0.75% CuEq). Here the porphyry shows pervasive K-feldspar, magnetite, chlorite type potassic alteration, with intensive quartz veinlets type "A" and "B" associated with chalcopyrite, pyrite and molybdenite mineralization. This evidence leaves this area open to the discovery of additional high-grade intervals at depth.
Building the Exploration Model
Drillhole CB-2282 intersected 317.6 m of high-grade mineralization from surface to 850 m depth is related with the Principal Porphyry. The intersections of the Drillholes CB-229 and CB-230 at 200 m to the south and north, respectively, continue delineating the extension of the High-grade, with CB-228 intersecting the main width flow with significant chalcopyrite. The three drillholes confirm a lateral continuity along 600 m over the horizontal strike and between elevations 2900 and 3200 masl. Nevertheless, drillhole CB-230 was terminated (elevation of 2600 m) within Principal Porphyry mineralization and shows evidence of nearby Endoskarn, two key components for developing High-grade Cu-Au potential.
A new battery of the drillholes CB-231, 232 and 233 has commenced to delineate limits of the high-grade component of the South Pit, 200m to the North of the CB-230 and 200m below Drillholes CB-228, 229 and 230 (at elevations of 2500 m and 2900 m).

See Press Release dated June 8, 2026QA/QC Testing Procedures
Drilling was supervised by Panoro personnel, with core logged, photographed, cut, and sampled at the Company's core facility in Cusco, Peru. Drill core was split in half, with one half submitted for analysis and the remaining half retained for reference. Core was sampled at nominal 2 m intervals, adjusted where required for geological contacts, alteration, mineralization, or structural features. Panoro's quality assurance and quality control (QA/QC) program included the regular insertion of certified reference materials, blanks, and duplicate samples into the sample stream.
Samples were prepared at ALS Minerals' sample preparation facility in Lima, Peru, and analyzed at ALS Minerals' accredited laboratory facilities in Peru. Analytical methods included fire assay for gold and atomic absorption and ICP techniques for copper, silver, molybdenum, lead, zinc, mercury, and multi-element analyses. ALS is an independent laboratory accredited to ISO 9001 and ISO/IEC 17025 standards.
