Geophysical Survey at Cotabambas Identifying Porphyry and Skarn Potential at Cotabambas Project, Peru
Vancouver, B.C., March 12, 2019 - Panoro Minerals Ltd. (TSXV: PML, Lima: PML, Frankfurt: PZM) ("Panoro", or the "Company" - https://www.commodity-tv.net/c/search_adv/?v=298884) is pleased to announce the completion of the 2019 geophysical survey at the Cotabambas Project. The completed program has yielded a number of principal advancements for the planning of the proposed drill program:
- Identified a large chargeability anomaly underlying porphyry mineralization exposed at surface, indicative of the potential for a new porphyry target at depth (see Figure 1);
- indicating the potential for skarn mineralization at depth where a high gravimetric zone is located in close proximity of the high chargeability anomaly and also in close proximity to the limestone formation exposed at surface corresponding to the outcroppings of skarn mineralization mapped at surface with high grades (see Figure 2); and
- High magnetics response over and to the sides of the zone of high chargeability, indicative skarn mineralization potential at the contact between a potential porphyry and the limestone unit.
Luquman Shaheen, President & CEO of Panoro states, “The results of the 3-D interpretation of the geophysical survey are demonstrating some interesting growth and scale potential for the Cotabambas Project. Both, or either of, the Porphyry and Skarn potential at Zone 1 of the Chaupec Target could yield important enhancements to the scale, grade profile and mine life for the current plan for the Cotabambas Project. We are hopeful that this potential will be further delineated with the drill program to commence immediately.”
The detailed ground geophysics testwork was completed at the Chaupec Target, in Cluster 2 of the Cotabambas Project. The survey covered an area of 0.5 km by 1.0 km and focussed on the northern extreme of Zone 1. The area covered by the geophysical program encompassed only a portion of the approximately 3 km long zone of outcropped skarn and porphyry mineralization at the Chaupec Target of Cluster 2. Magnetometry, IP and Gravimetry surveys were completed by Deep Sounding EIRL of Lima, Peru.
The area tested contains surface exposures of Skarn bodies of garnets and piroxenes intercalated with narrow porphyry dikes of quartz monzonite composition hosting copper minerals such as chalcocite, covellite, chalcopyrite, bornite and copper oxides reporting copper grades of up to 5.0% Cu. This geologic environment covers an area of approximately 400 m by 600 m elongated in northwest direction and remains open to the south.
The highest chargeabilities measured from 8 to 11 mV/V and are located from 120 m to 350 m depth below the skarn/porphyry dikes outcroppings, covering an area of 240 m by 550 m with the same strike of the copper mineralization. Areas of high magnetics (>0.116n.T.) are located next to and around the high chargeability zone. The high resistivity signatures (1800 to 3,000 Ohm/m) overlap the front of limestones with a smooth increase into the main chargeability zone. Finally the gravimetry found a high density zone (1.2 to 1.9 grms/cm3) in east-west direction crosscutting the high chargeability and magnetics.
The sharp change in strike in the outcropped Skarn overlaps the area of high density, high magnetics and high chargeability that may suggest the possible stock porphyry location as the principal source of the copper mineralization, skarns and porphyry dikes exposed in surface.
The main Cu-Au-Ag skarn bodies may be located near the porphyry stock in contact with the limestones. Panoro is planning a first phase drilling program of 2,000 m to 2,400 m to test the areas of surface exposures of skarn and porphyry mineralization and the underlying geophysical anomalies. The drill program will commence in March 2019.
Panoro Minerals is a uniquely positioned Peru focused copper exploration and development company. The company is advancing its flagship project, Cotabambas Copper-Gold-Silver Project and its Antilla Copper-Molybdenum Projects located in the strategically important area of southern Peru. The company is well financed to expand, enhance and advance its projects in the region where infrastructure such as railway, roads, ports, water supply, power generation and transmission are readily available and expanding quickly. The region boasts the recent investment of over $US 15 billion into the construction or expansion of four large open pit copper mines.
Since 2007, the Company has completed over 80,000 m of exploration drilling at these two key projects leading to substantial increases in the mineral resource base for each, as summarized in the table below.

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.
