Exploration Drill Holes
b>Hole CB-105 was collared 1,200m to the east of previously published hole CB-68 and drilled from the southeast to northwest to test for the depth extension of the Ccalla East deposit. From 667.2m to 957.6m, 290.4m of copper primary mineralization averaging 0.31% Cu, 0.12g/t Au and 2.7g/t Ag was intersected, including a number of intervals grading between 0.47% Cu to 0.84% Cu. From 989.9m to 1090.5m the hole intersected intervals of the principal porphyry grading from 0.26% Cu to 1.0%C u and 0.10g/t Au to 0.68g/t Au between barren latite dikes. The hole bottomed in mineralization at a vertical depth of 600m.
Hole CB-113 was collared in the Ccalla East deposit, also from the southeast to the northwest but 500m to the south of CB-105. No significant values were intercepted suggesting a potential southern limit to the Ccalla East deposit.
Hole CB-117 was collared at the northern end of the Ccalla deposit and targeted the deeper portions of potential northern extension of the supergene enrichment zone beyond the current resource model limits. From 55.8m to 124.2m, 68.4m of a mineralized leached cap was intercepted grading 0.45g/t Au and 2.5g/t Ag, including 18m grading 1.06 Au g/t and 3.8g/t Ag. This is underlain by 115.3m of oxide copper mineralization grading 0.48% Cu, 0.07g/t Au and 2.3 g/t Ag, including 12.0m averaging 0.96% Cu and 14.0m grading 1.65% Cu. The supergene mineralization is still open to the north and nearer to surface and is targeted for further extension with additional drilling in the future.
Hole CB-118 was collared between holes CB-68 and CB-105in the Ccalla East deposit, but directed to the southeast. From 222m to 608m, 386.7m of primary copper mineralization was intersected grading 0.27% Cu, 0.09g/t Au and 2.6g/t Ag, including 67.3m averaging 0.35%Cu, 0.07g/t Au, and 2.6g/t Ag, and 28.0m grading 0.43% Cu, 0.17g/t Au and 6.1g/t Ag.
Hole CB-119 was collared in Ccalla East 150m to the south of CB-118 and drilled to the northwest. From 353.7m to 705.0m, a number of intervals of primary copper mineralization grading from 0.17% Cu to 0.34% Cu were intercepted.
Step Out Drill Holes
Hole CB-114 was a step out hole at the north end of the Ccalla deposit. From 56m to 92.2m, 36.2m of oxide copper mineralization was intersected grading 0.56% Cu, including 15.1m of 0.80% Cu. At depth, two intervals of primary copper mineralization of 74.8m and 15.7m length and averaging 0.20% Cu and 0.10% Cu respectively were intersected.
Hole CB-115 was collared in the western border of the Ccalla deposit,. From surface to 4.2m, a mineralized leached cap was intersected grading 0.56g/t Au, 18.9g/t Ag. This was successively underlain by 114.5m of oxide copper mineralization averaging 0.36% Cu, 0.18g/t Au and 2.0g/t Ag, including 10.0m grading 0.93% Cu, 0.31 g/t Au, 2.4g/t Ag, and by 46.1m of primary mineralization grading 0.32% Cu, 0.16 g/t Au, 2.3g/t Ag. Three more intervals of primary mineralization were intersected, the last of which consisted of 119.6m averaging 0.61% Cu, 0.25g/t Au, 4.3g/t Ag, including 64.4m grading 0.82% Cu, 0.32g/t Au and 5.0g/t Ag. The hole bottomed in mineralization.

A map showing the locations of the drill holes is available at Panoro's website, www.panoro.com. Three drills continue working on the step-out, exploration and infill drilling targeting continued growth of the resource and upgrade of the high grade pit area to the Indicated category.
Panoro's strategic focus is to move its advanced stage projects to the feasibility and development stages and to explore its other projects. The Company owns the advanced Cotabambas Copper-Gold and Antilla Copper-Molybdenum Projects which include Inferred level resources of:
|404.1 Mt @ 0.42% Cu, 0.23g/t Au and 2.84g/t Ag @ 0.2% Cueq cut-off (AMEC 2012) (in situ content of 3.75 billion lbs. Cu, 3.0 million oz. Au, 36.9 million oz. Ag)|
|154 Mt @ 0.47% Cu and 0.009% Mo @ 0.25% Cu cut-off (AMEC, 2009) (in-situ content of 1.6 billion lbs. Cu and 30 million lbs. Mo)|
Panoro is very well positioned to continue advancing the exploration at the Antilla and Cotabambas Projects. The Company completed a $15 million financing in March 2013 and is planning to continue its exploration activities, updating the resource estimates for both projects in 2013 and commencing Preliminary Economic Assessments. Additional drill results will be announced as they are received from the ongoing exploration at Cotabambas Cu/Au/Ag Project.
Panoro's significant portfolio of properties is located primarily in the south-eastern region of Peru. This region contains a number of important copper and copper/gold deposits including Xstrata's Las Bambas and Antapaccay Copper Projects and the Tintaya Copper Mine. In September 2010, Xstrata announced US$5.7 billion of investment to develop the Las Bambas and Antapaccay projects. The region also includes First Quantum Minerals' Haquira Copper Project, HudBay Minerals' Constancia Copper Project and Southern Copper's Los Chancas Copper Project.
