Panoro Minerals Continues Delineating Mineralization at Maria Jose Target at Cotabambas Project, Peru
VANCOUVER, British Columbia, Aug.30, 2017(GLOBE NEWSWIRE) -- Panoro Minerals Ltd. (TSX-V:PML) (Lima:PML) (Frankfurt:PZM) ("Panoro", the "Company") is pleased to provide the results from an additional three drill holes completed at the Maria Jose Target at its 100% owned Cotabambas Cu/Au/Ag Project in Peru. The results are highlighted by Drillhole CB-161.
Drillhole CB-161, located 140 m southwest of previously announced hole CB-157, intersected the andesite volcanic package from surface to 39.7 m with oxide copper mineralization grading 0.54% Cu, 0.06 g/t Au and 2.52 g/t Ag, underlain by three intervals of primary copper mineralization of 56.3 m averaging 0.41% Cu, 0.05 g/t Au, 2.19 g/t Ag, 188.7 m grading 0.25% Cu, 0.04 g/t Au, 1.75 g/t Ag, and 22.9 m averaging 0.48% Cu, 0.08 g/t Au and 3.39 g/t Ag.The drill hole was terminated in mineralization.
Maria Jose mineralization is generally covered at surface with colluvium and has only limited outcrop. A previous geochemical rock chip survey identified two copper anomalies, MJ-1 and MJ-2 coinciding with strong IP and magnetic signatures.Drill holes CB-157 (from previous press release), CB-161, and CB-163 were located over a distance of 500 m across the MJ-2 anomaly. Drillhole CB-162 was located 160 m northwest of drillhole CB-161 to test the geophysical anomalies in this direction.
The following table details the more significant intersections.Drillhole location plans can be found at the company's website, www.panoro.com

Drill hole CB-162 is located 160 m to the northwest of drill hole CB-161, and intersected 74 m of quartz monzonite with minor potassic alteration as well as the volcanic hosting the mineralization. This hole intersected 123.8 m of oxide copper mineralization averaging 0.17% Cu, 0.02 g/t Au, and 0.98 g/t Ag, including 8.3 m averaging 0.32% Cu, 0.04 g/t Au, 1.43 g/t Ag, and 37.5 m grading 0.22% Cu, 0.03 g/t Au, 1.2 g/t Ag, underlain by 33.1 m of a mixed zone averaging 0.26% Cu, 0.03 g/t Au, 1.12 g/t Ag. The primary copper mineralization was intersected at depth in various intervals grading from 0.23% Cu to 0.32% Cu.
Drill hole CB-163 was collared 150 m to the southwest of drill hole CB-161, and intersected two intervals of quartz monzonite porphyry intruding the same volcanic package. From depths of 38.7 m to 187.1 m, 148.4 m of primary copper mineralization was intersected, averaging 0.28% Cu, 0.02 g/t Au, 1.51 g/t Ag.
The drilling results to date at the Maria Jose Target have shown that the extensive chargeability and magnetic anomalies associated with the Maria Jose zone are associated with varying levels of disseminated pyrite and significant levels of chalcopyrite hosted in the volcanic intruded by the quartz monzonite porphyry. Additional drilling will continue to test this anomaly to the east and west.
Luquman Shaheen, President & CEO, states, "The exploration drilling campaign at the Maria Jose Target of the Cotabambas Project continues to delineate additional mineralization.The intersection of oxide, near surface mineralization is encouraging as we look towards assessing the potential for a heap leach component to the project plan.The drill program is still early in its advancement, and a few additional drillholes are completed and awaiting the completion of logging, sampling or assay results.We expect the growth potential of the Cotabambas Project together with the growing strength of copper price to further well position Panoro Minerals."

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.
