ANNOUNCEMENT TO THE TORONTO STOCK EXCHANGE AND AUSTRALIAN SECURITIES EXCHANGE

PERTH, Western Australia, June 30, 2014 /CNW/ - The Board of RTG Mining Inc. ("RTG", "the Company") (TSX Code : RTG, ASX Code : RTG) is pleased to announce further high grade copper, gold and iron intercepts in both the North and South Mineralized Zones at the Mabilo Project in the Philippines.

Continued diamond drilling has also extended the strike of the South Mineralised Zone by 350m. The advances in geological understanding continue to highlight down dip potential and extensions to the system in the north and south zones.

Significant work has also been undertaken in re-logging of previously drilled holes to get better detailed geological understanding to help build 3 dimensional models and give better data for future targeting of holes. A further update will be released upon completion of the re-logging and the detailed geological review. Reported widths are drill intercepts, true width will be less.

Highlights of the ongoing drilling program include –

  • Hole MDH-053 intersected primary mineralised Magnetite Skarn in the South Mineralised Zone at 108m down hole and then Garnet Skarn at 160m down hole. Significant assays–


    47.05m @ 1.64 g/t Au, 1.40% Cu and 55.76% Fe and

    18.00m @ 3.12 g/t Au, 1.25% Cu and 42.16% Fe and

    18.15m @ 3.29 g/t Au, 0.80% Cu and 41.73% Fe

  • Hole MDH-054 intersected primary mineralised Magnetite Skarn in the North Mineralised Zone at 171m down hole. The intercept assayed:

    17.40m @ 1.80 g/t Au, 2.04% Cu and 48.69% Fe

  • Hole MDH-055 intersected weakly mineralised primary Magnetite Skarn in the South Mineralised Zone at 112m down hole. The intercept assayed:

    10.00m @ 1.16 g/t Au, 0.47% Cu and 43.64% Fe

  • Hole MDH-057 intersected primary mineralised Magnetite Skarn in the South Mineralised Zone at 129m down hole. The intercept assayed:

    24.70m @ 3.41 g/t Au, 2.98% Cu and 51.56% Fe

ABOUT MABILO

The Mabilo Project is located in the Camarines Norte Province, Eastern Luzon, Philippines. It comprises one granted Exploration Permit (EP-014-2013-V) of approximately 498 ha and Exploration Permit Application EXPA-000188-V of 2,820 ha. The Project area is relatively flat and is easily accessed by 15 km of all-weather road from the highway at the nearby town of Labo.

Drilling is currently focused on defining the SE strike and SW down dip extent of the large South Mineralised Zone and testing the strike extension of mineralisation to the north and south of the North Mineralised Zone.

South Mineralised Zone

Drilling has concentrated on the South Mineralised Zone which is substantially larger than the North Mineralised Zone.

Re-logging of the drill holes and three dimensional modelling in this Zone has facilitated better targeting for future holes. An updated long section view of isotropic copper grade shells is illustrated below.

Drilling on two sections to the South East of previously reported MDH-046 has significantly extended mineralisation along strike with two intercepts of high grade copper and gold of significant thickness and grades.

MDH-053

A vertical hole drilled to test the strike continuation of the high grade mineralisation in MDH-40 and 16. The hole intersected magnetite-chalcopyrite mineralisation from 108 to 182.8 metres, visually consistent with the results from MDH-40 and MDH-16.

North Mineralised Zone

Drilling on the North Mineralised Zone has concentrated on exploring the north and south strike extensions of the modelled magnetite body. The mineralisation appears to be localised along the margin of the diorite intrusion and plunges shallowly to both the north and south of the modelled zone which appears to reflect a zone where the mineralisation is both wider and closer to the surface.

MDH-054

An angled hole to further test the mineralisation in MDH-52. The hole intersected massive magnetite-chalcopyrite from 171 - 190 metres where it passed into marble.
