Panoro Minerals Extends Potential of Oxides Mineralization in Maria Jose, Petra and David Targets of Cluster 1 at Cotabambas Project, Peru
VANCOUVER, B.C., Dec. 11, 2017 (GLOBE NEWSWIRE) -- Panoro Minerals Ltd. (TSXV:PML) (Lima:PML) (Frankfurt:PZM) ("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. Highlights are as follows:
- Petra Target: Drillhole CB-172 intersected from 0 to 78.8m oxide copper mineralization in a quartz monzonite porphyry intruding diorite and averaging 0.32% Cu, 0.08 g/t Au, 2.2 g/t Ag, including two intervals of 20.4m grading 0.48% Cu, 0.12 g/t Au, 2.6 g/t Ag, and 10.0m averaging 0.57% Cu, 0.14 g/t Au, 2.2 g/t Ag.
- Maria Jose 1 Target: Drillhole CB-180 intersected from 2.2m to 115.0m oxide copper mineralization at the contact between andesite volcanics and quartz monzonite porphyry and averaging 0.23% Cu, 0.02 g/t Au and 1.1 g/t Ag, including two intervals of 9.0m grading 0.43% Cu, 0.03 g/t Au, 1.1 g/t Ag and 34.9m averaging 0.30% Cu, 0.02 g/t Au, 1.3 g/t Ag.
- David Target: Drillhole CB-175 intersected from 54.8m to 142.4m oxide copper mineralization in a quartz monzonite porphyry intruding andesite volcanics and averaging 0.20% Cu, 0.07 g/t Au, 1.8 g/t Ag, including two blankets of 7.6m grading 0.39% Cu, 0.13 g/t Au, 2.4 g/t Ag, and 8.6m averaging 0.29% Cu, 0.08 g/t Au, 2.3 g/t Ag.
Luquman Shaheen, President & CEO of Panoro, states, “The drilling program continues to intersect oxide mineralization in the satellite targets of Cluster 1 of the Cotabambas Project. The oxide mineralization intersected at or near surface is demonstrating the potential to include a heap leach and SX/EW component to the current project plan outlined in the Preliminary Economic Assessment (PEA). Panoro is waiting for additional drill assay results from drill holes targeting the sulphide mineralization intersected in previously announced drill results from the Maria Jose Target. We look forward to continuing the exploration program in 2018 to continue expanding the mineralized zones intersected in Cluster 1, around the current resource, where the 2017 drill results will guide targetting of higher grade near surface mineralization. In 2018 Panoro’s exploration work will also step out into Cluster 2 where skarn and porphyry-style copper mineralization has been identified by rock chip sampling, mapping and geophysics.”
Petra Target
The target is located 500m to the West-Northwest of the PEA pit at an elevation 250m lower than the pit limit. Approximately 95% of the area is covered by soils and colluvial deposits.
Drillhole CB-172 is located 30m to the west of the previously published drillhole CB-171 but oriented in the opposite direction. Drillhole CB-174 is located 90m to the west and oriented to the south where the quartzmonzonite was intersected without significant values.
In summary, four holes, CB-171, CB-172, CB-173 and CB-174, were drilled along a SE-NW line across the Petra Target. The results for CB171 and CB173 were published on October 11th. An oxide blanket with significant copper grades was intersected by holes CB-171, CB-172, and CB-173 along a N-S structural control leaving mineralization open toward the David target located 500m to the north.

David Target
The David target is located 500m to the north of the Petra target and 800m to the Northwest of the PEA pit, at an elevation 260m lower than the pit limit. Four holes, CB-175, CB-176, CB-177 and CB-178, were drilled along a line across the same N-S structural control seen at the Petra target.

Maria Jose 1 Target
The Maria Jose 1 target is located 1.5 km to the Northeast of the PEA pit and 600m to the Southwest of Maria Jose 2 target. At this target, four holes, CB-179, CB-180, CB-181 and CB-182, were drilled over an area of approximately 400m by 500m.
Drillhole CB-181 is located 130m to the southeast of drillhole CB-180 and intersected quartz monzonite porphyry intruding andesite volcanics, including two blankets of oxide copper mineralization underlain by primary copper sulphides. See results in the table below.
Drillhole CB-182 is located 210m to the southwest of drillhole CB-180 and also intersected quartz monzonite porphyry intruding andesite volcanics. The oxide copper mineralization is hosted in both lithologies and is still open at depth.
In summary, drillholes CB-180 and CB-181 intersected near surface oxide copper mineralization, and drillhole CB-182 intersected similar mineralization starting from 48.7m below the surface. As with the oxide blankets intersected at other targets, there may be structural controls on the distribution of higher copper grades that could be targeted with additional drilling.
The following table details the more significant intersections. A location plan can be found at the Company’s website, https://www.panoro.com/site/assets/files/3954/press_release_december_map_modif.jpg

The 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 updated PEA will be realized. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
