About Panoro

Panoro Minerals is a uniquely positioned Peru and Copper focused exploration company. The Company is advancing a significant project portfolio in the key Andahuaylas-Yauri belt in south central Peru, including its advanced stage Cotabambas Copper-Gold-Silver-Molybdenum and Antilla Copper-Molybdenum Projects.

Since 2007, the Company has completed over 70,000 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 PEAs will be realized. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.

The PEA Technical report is found on SEDAR and is also available here.

The Antilla Copper-Molybdenum project is located 140 km southwest of the City of Cusco in the Apurimac Region of Southern Peru. The centre of the project area lies at UTM coordinates 8,414,000N and 718,500E. The project is accessed via the main Cusco to Nazca highway and the unpaved main access road to the small village of Antilla. The project was acquired by Panoro in 2007 and is 100% owned by the Company.

The Antilla project has an indicated resource estimate of 188.5 million tonnes at an average grade of 0.40% copper and 0.009% molybdenum and an inferred resource of 145.9 million tonnes at 0.28%Cu and 0.009% Mo at a cut-off of 0.20%Cueq. The new resource was estimated by Tetra Tech Canada (December 2013) and the results are available here and reflects a 38% increase in contained copper and 53% increase in contained molybdenum. The strip ratio of the conceptual pit shell used to constrain the mineral resource is reduced to 1:1 from 2.5:1 in the 2012 resource estimated by AMEC Peru.

The resource estimate has been completed utilizing all drill and assays results available to June 11, 2013, based on the results of 9,130 meters of drilling by Panoro (49 drill holes) and 5,162 meters of drilling (39 drill holes from drilling by others). The high grade mineralization defined before by AMEC has been upgraded to Indicated status in the Tetra Tech study and could be amenable in a potential starter pit within the conceptual life-of-mine. However, a pit optimization process will be included in a Preliminary Economic Assessment to be completed at the end of Q2 2014.

The potential to increase the resource at the Antilla project includes a number of targets. Firstly, the potential for the extension of the supergene sulphide mineralization in the East Block to the north and northwest was identified by five holes where the mineralization remains open for future exploration. Secondly, in the West Block, located 2.5 km from the East Block, the potential exist for additional supergene sulphide mineralization similar to the East Block based on the presence of chalcocite in the previously drilled holes in the area with some drill intervals assaying above 0.3% copper particularly in Drillhole ANT-13, 15, 16S and 6B. Thirdly, the new geochemistry survey in rocks shows an extended anomaly of molybdenum (>100ppm Mo) and copper that suggest the mineralization continuity and a possible connection of the East block with the West block. Fourthly, the geochemistry anomalies are extending also to the east of the current resources area, to the Chabuca zone, extending the potential to a global area of 2.5km by 5km, east west direction. Fifthly, in the western extreme of the property a new exploration target named Piste was recently discovered, consisting of outcropping porphyry and skarn-type mineralization hosted by sediments.
