MELBOURNE, Oct. 30, 2018 /CNW/ - OceanaGold Corporation (TSX: OGC) (ASX: OGC) (the "Company") is pleased to announce updated exploration results highlighting continued high-grade gold intersections from the Martha Project (the "Project") at the Company's Waihi Gold Mine ("Waihi") located in New Zealand.

  • 4.8 m @ 8.16 g/t Au Dreadnought vein

Mick Wilkes, President and CEO of OceanaGold said, "These latest drilling results from the Martha Underground continue to increase our confidence in the potential resource at Waihi, and further continues to identify areas of high-grade mineralisation that sit deeper and laterally to our exploration targets."

He added, "These recent drill results will be included into the Martha Underground resource model scheduled as part of the annual Resource and Reserve update. In August, we increased the Indicated and Inferred Resource significantly and with further exploration drilling, we are confident of defining a sizeable resource that will further support the extension of the mine life at Waihi."

"The Waihi operation has delivered significant value to shareholders for a number of years. It has also contributed significant socio-economic benefits to the town of Waihi and to New Zealand. OceanaGold is very proud of its track record for operating to the highest of environmental and social standards with a long, successful and rich history of sustainable development in New Zealand and in other jurisdictions around the world."

Following the significant increase in Mineral Resources reported in August 2018 for the Martha Project at Waihi, underground drilling has continued at multiple drill points along the two underground drill drives. Since August 2018, approximately 10,000 metres have been drilled at Waihi with a focus on identifying and defining mineralisation along sections of the Martha, Royal, Empire, Dreadnought and Rex veins.

In total, these veins along with the Edward vein have a combined strike length of approximately 3.2 kilometres with a maximum dip extent of approximately 500 metres (Figure 1 and 2). Recent drilling has intersected significant gold mineralisation both deeper in the central Martha area and eastward towards the current mining fronts approximately 200 metres away on the Empire Vein.

Drilling from surface and underground is in progress on the Rex Vein where a significant intersection of 2.7 metres (true width) at 28.4 g/t gold supports earlier intersections on the Rex Vein of up to 2.9 metres (true width) at 32.3 g/t gold.

In addition, the drill drives which support the underground drill program are advancing well with the 920-drill drive now complete, while the 800-drill drive is advancing ahead of schedule being over 60% complete with a targeted completion at the end of the first quarter of 2019. 

The continuing intersection of high-grade mineralisation supports the outlined exploration target reported in August with a potential volume of between 5 million and 8 million tonnes at a grade of between 4.0 g/t and 6.0 g/t gold. This exploration target is based on the assessment of surface and underground drilling data collected by the Company in addition to the significant amount of historical and archived geological and mining data from over a century of mining activity at Waihi.  Exploration targets are conceptual in nature; there has been insufficient exploration to define a mineral resource of the potential volume and grade stated and that it is uncertain if further exploration will result in the target being delineated as a mineral resource of this size and grade.
