MELBOURNE, June 7, 2016 /CNW/ - OceanaGold Corporation (TSX/ASX/NZX: OGC) (the "Company") is pleased to provide an update on its exploration program across its operations in the United States, New Zealand and the Philippines. This update follows the update the Company provided to the market on February 29, 2016 and results herein reflect drilling after this date.

Key Highlights

• Drill results at Haile continue to demonstrate a high-grade resource.

• Drill results at Waihi continue to demonstrate resource expansion opportunities from numerous high-grade targets including Correnso Deeps, Empire and Daybreak.
• Recent significant gold intersections at Waihi include 4.8 metres @ 17.5 g/t and 5.1 metres @ 8.2 g/t from Correnso Deeps, 2.9 metres @ 21.3 g/t and 3.1 metres @ 20.6 g/t from Daybreak, 3.0 metres @ 35.7 g/t, 3.0 metres @ 9.9 g/t and 6.0 metres @ 14.7 g/t, 2.4 metres @ 10.9 g/t and 2.6 metres @ 5.6 g/t at other nearby veins.
• Drill results at Macraes demonstrate an extension of known mineralisation both to the north and southeast of the previously reported Coronation North resource.
• Recent significant gold intersections at Coronation North include 40 metres @ 3.6 g/t¹, 15 metres @ 1.7 g/t, 21 metres @ 2.9 g/t, 18.7 metres @ 1.7 g/t and 4 metres @ 8.9 g/t¹ and at Frasers Underground 15.3 metres @ 4.0 g/t¹ and 78.5 metres @ 2.4 g/t¹.
• Exploration activities have commenced in the broader FTAA area in the Philippines with drilling scheduled to commence in the third quarter of 2016.

Mick Wilkes, President and CEO stated, "In 2016, we initiated an extensive exploration program with over 100 kilometres of drilling planned for the year and an investment of over US$30 million. In the first quarter, we were greatly encouraged from the initial drilling from this program. I am pleased to report strong ongoing results which further demonstrate the significant resource potential that exists in our assets." He added, "In addition to expanding our resource base, our exploration program will provide important inputs to the technical studies at Haile and Waihi already underway. I am confident these studies will demonstrate considerable additional value given the success of the exploration program to date."

Haile Exploration

At Haile, drilling has focused on expanding the resource at the Horseshoe deposit through diamond drilling of 42 holes utilising four surface drill rigs and completing over 12 kilometres of drilling since the start of the year. Drilling to date supports the current resource estimate and will feed into an updated resource estimate scheduled for the second half of 2016. Further work has been directed towards target definition and the planning of extensional and infill drilling of open pit resources and additional underground targets. In support of this work, the Company has commenced a geophysical survey which is expected to be completed in the third quarter of 2016.

Additionally, the Company continues to advance the Haile underground technical study on the potential of Horseshoe as an underground mine, and investigating the development of an exploration tunnel to further define underground reserves. Furthermore, an optimisation study which will incorporate an updated resource estimate for the open pit and the Horseshoe deposit is advancing well. The primary focus of this study is to optimise the open pit design and the interface with a potential underground operation.

Waihi

At Waihi, the Company has completed approximately 16 kilometres of drilling in 2016 with three underground and four surface drill rigs. Underground diamond drilling has focused on reserve and resource drilling of Correnso Deeps and Daybreak (Figures 3-4). Geological and resource models have been updated on these veins. Mine design and planning in preparation for development, which is expected to commence in the third quarter of 2016 has been completed. Significant results are listed in Table 2 with additional assays pending.

Surface diamond drilling has focused on testing the resource potential of the major lodes, linking veins and stockwork zones beneath the current open pit. Significant results from this drilling are listed in Table 3 and illustrated in Figure 5.

Exploration drilling of other untested targets within the Waihi epithermal continued from both surface and underground platforms with significant results listed in Table 4 and illustrated on Figure 6.

A further 20 kilometres of drilling is currently scheduled for the remainder of 2016 at Waihi, including further drilling on the WKP prospect in the Hauraki region where previous drill campaigns returned high grade intercepts of 9.7 metres (7.5 metres true width) @ 17.2 g/t Au and 7.9 metres @ 5.1 g/t Au.

Macraes Exploration

At Macraes, the Company has drilled over 14 kilometres in 2016 with a focus on resource development drilling at Coronation North, Coronation open pit, Coronation South, Horse Flat and Frasers Underground targets as shown on Figure 7.

• Coronation North: 91 holes for 10,247 metres completed with a 50 metre x 50 metre drilling pattern and investigating potential extensions to the gold mineralisation to the north and southeast;
• Coronation open pit: six holes for 814 metres to follow-up on previous intersections;
• Coronation South: seven holes for 847 metres to investigate the potential for ore shoot repetition between Deepdell North and Coronation;
• Horse Flat: five holes for 386 metres targeting the Horse Flat Fault for a repetition of fault drag mineralisation seen elsewhere in the Macraes Goldfield; and,
• Frasers Underground: 13 holes for 1,850 metres testing down plunge extensions and a sheeted vein target.

Resource development drilling within the Hydes-Macraes Shear Zone continues to deliver encouraging results as tabulated in Table 5 and on Figure 8. Drilling completed at Coronation North since the start of the year has extended known mineralisation a further 100 metres to both the southeast and north and further drilling is planned for the remainder of the year.

Resource development drilling at the Frasers Underground, as shown on Figure 9, has continued to extend Panel 2 down plunge and exploration in the 3A Panel area has discovered a sheeted vein system that in the future may be amenable to bulk underground mining. Significant intersections are listed in Table 6.

Philippines Exploration

In the Philippines, the Company has commenced exploration activities within the broader Financial or Technical Assistance Agreement (FTAA) area including six kilometers of drilling (see Figure 10). Within the FTAA, six large copper-gold soil geochemistry anomalies, the largest measuring over two kilometres by one kilometre, have been defined with supporting rock chip and channel sampling indicative of both porphyry copper-gold and intermediate sulphidation epithermal gold mineralization (Figure 10). Target definition work across six priority targets consisting of further geologic mapping, soil sampling and ground geophysics has commenced with drilling anticipated to commence in the third quarter of 2016. The Company also continues to drill test its highest ranked targets within the Didipio Mine Permit Area and has completed approximately two kilometres of a three kilometre program.
