MELBOURNE, March 7, 2019 /CNW/ – OceanaGold Corporation (TSX:OGC) (ASX: OGC) (the “Company”) is pleased to announce an updated Mineral Resource estimate for the Martha Underground Project (the “Project”) and recent exploration results highlighting continued high-grade gold intersections at the Company’s Waihi Gold Mine (“Waihi”) located in New Zealand.

Highlights

• Increased total Indicated Resource by 136% to 331,000 ounces of gold.
• Increased total Inferred Resource by 97% to 667,000 ounces of gold.

Significant Drill Results

 

Mick Wilkes, President and CEO, “I am very pleased to announce a further increase to the mineral resource estimate for the Martha Underground Project. Over the past two years, we have made prudent investments in extensively drilling out the mineralised structures beneath the Martha Open Pit. Since that time, we have reported dozens of significant drill intercepts and a growing resource which has now culminated into an Indicated Resource of 331,000 ounces of gold and Inferred Resource of 667,000 ounces.”

“The consenting (permitting) process was completed nearly a month ago and we continue to add significant resources as we seek to achieve our exploration targets. We are in the process of implementing the project development and mine plans. Once fully developed and ramped-up, production from the Martha Underground is expected to increase to recent historical levels while delivering significant socio-economic benefits to New Zealand.”

Over the course of the next twelve to eighteen months, the Company will continue its extensive exploration program along the two underground drill drives to further discover and convert resources. The Waihi vein system is extensive and the primary structures such as the Martha, Empire, Edward and Royal veins are in part well defined. The exploration target is associated with these structures, however, additional veins, notably Dominion, State, Republic and Harry that are branches of and linking splays between these major veins are also returning high-grade intersections.

Following positive updates in August 2018 and October 2018 for the Martha Underground, drilling has continued at multiple drill locations extending 900 metres along two vertically separated underground drill drives (800m-drill drive and 920m-drill drive, Figure 1) and from several surface locations. These drives are advancing well with the breakthrough from the 920-drill drive to the Martha open pit now established and the 800-drill drive over 90% complete.

Since the commencement of the Martha Underground drill program, approximately 30,700 metres have been drilled to define mineralisation along sections of the Martha, Royal, Empire and Rex veins that support the geological and resource model. Following receipt of the Martha Underground consent, the focus of drilling with six underground rigs and two surface rigs is balanced between growing the Resource and converting areas to an Indicated Resource status sufficient to support feasibility studies and mine planning.

The intersection of high-grade mineralisation to date supports the exploration target reported in August 2018 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.

Mick Wilkes added, “The recent drill results at Waihi continue to demonstrate the significant exploration potential at the Martha Underground. We will continue to invest in our extensive drill program from the two underground drill drives and have allocated a budget of over $11 millionfor 2019 to go with the $8 million planned spend for our newly discovered WKP prospect which we reported an initial resource of 234,000 ounces of gold in the Indicated category and 401,000 ounces of gold in Inferred Resources.”
