(All financial figures in US Dollars unless otherwise stated)

MELBOURNE, Dec. 12, 2016 /CNW/ - OceanaGold Corporation (TSX/ASX/NZX: OGC) (the "Company") is pleased to provide an update on its exploration program across operations in the United States, New Zealand and the Philippines. The exploration update follows the update the Company provided to the market on 15 September 2016 ("September update") and results herein reflect drilling after this date.

Key Highlights

  • Completed a 66-hole infill drilling program at the Horseshoe deposit at Haile with recent significant intercepts that include 16.6m @ 29.9 g/t Au, 72.3m @ 5.0 g/t Au and 43.1m @ 9.5 g/t Au.
  • Increased Greenfields exploration ground in the Carolinas by 50% from the start of 2016 and commenced regional drilling of the Longleaf target.
  • Increased the Coronation North Measured and Indicated Resource at Macraes by over 60% to 218 koz gold.
  • Continued exploration success at Waihi from underground and surface drilling yielding significant intercepts that include 10.8m @ 9.25 g/t Au and 97.0 g/t Ag and 1.8m @ 20.1 g/t Au and 836.3 g/t Ag from surface, and 2.6m @ 93.80 g/t Au and 125.1 g/t Ag and 7.9m @ 24.33 g/t Au and 79.9 g/t Ag from underground.
  • Continued exploration success at Macraes including Nunns: 6.0m @ 3.2g/t Au and 3.0m @ 7.5 g/t Au; Coronation: 8.9m @ 1.7 g/t Au, 8.4m @ 1.8 g/t Au and 5.0m @ 2.9 g/t Au and Frasers Underground: 6.9m @ 3.5 g/t Au, 7.6m @ 3.2 g/t Au and 11.4m @ 2.1 g/t Au.
  • Recommenced exploration within the FTAA in the Philippines including diamond drilling at Mogambos and Luminag prospects.

Mick Wilkes, President and CEO said, "Our 2016 exploration program continues to demonstrate the significant and exciting organic growth potential of our business which represents low cost, low risk accretive value drivers for the Company. We have also significantly increased our land footprint in the Carolinas where we are sharpening our focus on the potential for additional Haile-like deposits in the region." He added, "The drill results at Horseshoe continue to increase our confidence in the high-grade nature of the deposit while at Waihi, our exploration target is to discover an additional one million ounces of resource over the medium term."  

Haile Exploration

The Company will complete approximately 30,000 metres of drilling with four diamond drill rigs at Haile in 2016. Since the September update, the Company received assays for the final 23 drill holes of the recently completed Horseshoe drill program (Figure 1) with significant intercepts listed in Table 1. The drill results continue to demonstrate the quality of the deposit with high-grade and generally relatively wide intercepts.

Following the completion of the initial Horseshoe drill program, focus moved to better understanding the potential of other resources within the Haile Gold Mine area, including the underground Palomino target where 11 drill holes for 5,444 metres were recently completed (Figure 2) with assays pending. The Palomino target currently sits outside of the current resource at Haile.

The results of the exploration program at Haile will be a major input into the Company's optimisation study currently underway and on schedule for completion mid-2017.

Over the course of 2016, the Company has increased its Greenfields exploration ground by approximately 50% from the start of the year and commenced drilling of the Longleaf target. Additionally, the Company continues to progress target generation activities with the interpretation and integration of geology and drill hole data with magnetic, electro-magnetic, gravity, and induced polarization data to identify and prioritise both near mine and Greenfields targets.

Waihi Exploration

Approximately 33,000 metres of drilling has been completed in 2016 with three underground and up to five surface drill rigs at Waihi. Surface diamond drilling continues to produce encouraging results intersecting mineralisation over significant widths while testing the resource potential of major lodes, linking veins and stockwork zones beneath the current Martha open pit. Significant results from this drilling are listed in Table 2 and illustrated in Figure 3.

Underground diamond drilling has focused on reserve and resource additions at Daybreak, Empire and Christina veins. Since the September update, the Company received permits to mine in an area that adjoins the Correnso mine to the west and where high-grade intercepts on the strike extensions of Christina demonstrate potential for reserve additions. Significant results from underground drilling at Waihi are illustrated in Figures 3 through 5 and listed in Table 3 with additional assays pending.

Exploration drilling of new targets within the Waihi epithermal system continues from surface with both the Rex and West targets tested this quarter with assays pending.

Macraes Exploration

The Company will have completed approximately 27,000 metres of drilling in 2016, focusing on resource conversion, extension and identifying new zones of mineralisation from a pipeline of targets along the 35-kilometre Hyde-Macraes Shear Zone including Coronation North, Coronation, Mt Highlay, Nunns, Round Hill/Golden Point and Frasers Underground (Figure 6).

Since the September update, the Company completed two drill holes for 510 metres at Coronation North targeting a high-grade ore shoot with assays pending. The drill program at Coronation North, following the maiden resource announced in November 2015, has increased the total Measured and Indicated ounces by 62% to date (Table 4). The Company remains on track to receive its permits required to advance Coronation North into development which is expected to commence in the first quarter of 2017.

At the Coronation open pit, 15 holes for 3,363 metres were drilled testing a NW-SE striking extension to mineralisation (Figure 7). The drilling confirmed mineralisation of significant width and grade in the targeted area (Table 5).

At the Nunns prospect, 20 holes for 1,295 metres were drilled to define a higher-grade shoot discovered in the third quarter. Significant results from drilling are shown in Figure 8 and in Table 6.

At the Frasers underground, approximately 1,300 metres of resource definition drilling continues to define the down-dip extent of Panel 2 (Figure 9, Table 7). The remainder of the year will focus on completing infill drilling of Panel 2 in advance of a resource update expected in the first quarter of 2017.

Philippines Exploration

In the Philippines, the Company commenced infill and resource extensional drilling of the Didipio underground deposit, while regionally, exploration activities recommenced across several priority targets within the broader FTAA area.

At the Didipio underground, four holes for 1,010 metres of infill drilling were completed, with all four holes intersecting mineralisation, increasing confidence in the current known underground resource. Additionally, two holes of the resource extensional drill program confirmed mineralisation extending below the current Didipio underground resource. A third drill hole has commenced.

Within the broader FTAA area, the first drill holes commenced testing the Mogambos prospect which is characterised by broad (1.6km x 1km) and coincident copper (>200ppm) and gold (>50ppb) in soils anomaly centred on diorite and monzonite intrusive bodies. Drilling also got underway on the Luminag prospect characterised by a broad resistivity high and gold in soils (>50 ppb) anomaly. On the D'Fox prospect, historic drill core was re-logged and a revised geological model was generated which indicates mineralisation intersected to date remains open and a priority drill target. Elsewhere within the FTAA, detailed geologic mapping and geochemical sampling continued on the Papaya and TNN prospects.

Mick Wilkes went on to say, "We will continue our intensive focus on adding high-margin ounces through the exploration drill programs at our well-endowed gold districts while we deliver the Haile project, through commissioning and into commercial production in 2017."

Maps and tables showing drilling results can be accessed with the following link: http://www.oceanagold.com/investor-centre/filings/.  In line with ASX listing requirements, material information summary in relation to the change in resource at Macraes (Coronation North), and JORC Code Table 1 for Haile, Waihi and Macraes exploration results are appended to this release and available on the Company's website at www.oceanagold.com.
