OceanaGold continues drilling high-grade gold intercepts during resource conversion at Wharekirauponga New Zealand




OceanaGold Corporation (TSX: OGC) (ASX: OGC) (the “Company” – https://www.commodity-tv.com/ondemand/companies/profil/oceanagold-corp/) is pleased to announce that continued resource conversion drilling includes multiple intersections of high-grade gold and silver mineralisation at the Companyâ€?s Wharekirauponga (WKP) prospect in New Zealand. The drill results reported in this release are from the Companyâ€?s 2021 drill program, in which ten drill holes were completed for a total of 4,940 metres along the East Graben vein zone, in addition to 1,003 metres on other targets.

Highlights from the 2021 drill program include (estimated true width):

1 g/t Au and 73.4 g/t Ag over 10.3 metres from 377.0 metres, EG HWS*, (WKP101)

5 g/t Au and 41.4 g/t Ag over 10.2 metres from 393 metres, EG*, (WKP101)

2 g/t Au and 61.0 g/t Ag over 6.8 metres from 426.7 metres, EG FW*, (WKP101)

7 g/t Au and 28.3 g/t Ag over 9.1 metres from 398.7 metres, EG HW*, (WKP106)

7 g/t Au and 29.0 g/t Ag over 4.5 metres from 412.0 metres, EG HWS* (WKP106)

5 g/t Au and 26.9 g/t Ag over 15.7 metres from 419.0 metres, EG* (WKP106)

*EG = East Graben vein, HW = hanging wall vein, FW = footwall vein, HWS = hanging wall splay

Since the February 2020 mineral resource update, 8,916 metres have been drilled at WKP, predominantly on resource conversion drilling of the East Graben (“EG”) Vein in addition to a further 2,518 metres supporting geohydrological studies and geotechnical studies. Results are in line with expectation and are anticipated to increase confidence in the geological and grade continuity of the prospect.

A full geological and resource model update to incorporate 2020 and 2021 drilling is in progress for inclusion in the Company�s annual Reserve and Resource statement, which will be released March 31, 2022.

Scott Sullivan, Acting President & CEO of OceanaGold said, “The drill results at WKP continue to demonstrate the significance of this discovery for OceanaGold. Step-out exploration drilling in 2021 confirmed that the East Graben vein remains well developed a further 200 metres along strike to the south, is mineralised and remains open in multiple directions. This yearâ€?s drill campaign is already underway with two rigs, and we are continuing to focus on resource conversion drilling of the East Graben vein zone. Our next Mineral Resource update for WKP is expected at the end of the first quarter of this year. The Company has allocated US$10 million for exploration efforts, a significant increase to the budget, as we seek to expand the potential of WKP and to further demonstrate the significance of this discovery.”

“Meanwhile the Company continues to advance the permitting process and expects to lodge the permit applications with the Regional and District Councils in the first half of 2022. The critical path to success remains the consenting process however, while the process is ongoing, we continue to advance our technical studies. As mentioned last year, we have expanded the scope of the Waihi North Project given the potential scale we see, and the need to complete additional technical works to allow for optimal mine plans and designs.”

“The Waihi District has the potential to create significant socio-economic contributions for the communities in the Coromandel region and for New Zealand. This includes significant in-country investments and a substantial increase to direct and in-direct employment opportunities. We are envisaging the development of a mine that aligns well with the Companyâ€?s commitment to climate change. OceanaGold is one of the top-rated ESG gold miners globally. We operate to the highest environmental and social standards which has enabled us to run a successful and responsible mining business in New Zealand for over three decades.”

The Company commenced exploration on the WKP underground target in August 2017 and to date has drilled 37.2 kilometres in 83 holes (Figures 1 to 6). In February 2020, the Company reported an updated Indicated Resource of 1.0 million tonnes grading 13.4 grams per tonne gold (“g/t Au”) and 25.5 grams per tonne silver (“g/t Ag”) for 421,000 ounces of gold and 803,000 ounces of silver on the EG Vein. Additionally, an Inferred Resource of 1.9 million tonnes at a grade of 12.0 g/t Au and 20 g/t Ag for 717,000 ounces of gold and 1,230,000 ounces of silver was reported, with more than 80% of the Inferred Resource contained within the East Graben and two high-grade footwall veins. The remaining resource reported is from the East Graben footwall and hanging wall veins, including approximately 2% of the resource from the parallel T-Stream vein, which has yet to be further explored (Figure 2).

A resource conversion drill program initiated in 2021 continues in 2022 with 16.1 kilometres planned on the EG vein system to increase the Indicated Resource in support of the Waihi North Project technical study. This resource conversion drilling continues to improve the understanding of the structural architecture of the EG Vein and supports grade continuity within the southern mineralised shoot and associated hanging and footwall splays (Figures 2, 3, 4, 5 and 6). Significant intersections include hole WKP106 with estimated true widths of 9.1 metres at 23.7 g/t Au from 398.7 metres, 4.5 metres at 19.7 g/t Au from 412.0 metres, and 15.7 metres at 21.5 g/t Au from 419.0 metres (Figure 5, Table 1) and WKP101 with estimated true widths of 10.3 metres at 39.1 g/t Au from 377.0 metres, 10.2 metres at 26.5 g/t Au from 393 metres, and 6.8 metres at 29.2 g/t Au from 426.7 metres (Figure 6, Table 1).

Several targets are recognised for future resource extension. On the southern shoot of the EG vein and hanging wall splay, > 50 gram x metre intercepts define opportunities both up- and down-dip on the former and up-dip on the latter (Figure 3 and 4). Recent step-out drilling of hole WKP100 has also confirmed the EG Vein continues along strike a further 200 metres to the southwest. This along strike opportunity provides up-dip potential within the currently recognised window of mineralisation between -200 masl and +100 masl within the favourable host rhyolite flow (Figure 3). The EG Vein remains open both to the southwest and northeast of the currently defined 1,200 metre strike length. Additionally, T-Stream and Western veins have historic intersections (see OceanaGold Corp announcement 7 November 2019) that warrant further drilling to fully understand their potential within the larger WKP epithermal system.

In conjunction with resource and step-out drilling at WKP, a 1,028 metre program has been executed to provide hydrogeological information for regulatory approvals and mine design purposes. Information on the groundwater system is being gathered from test work undertaken via packer tests and falling head tests to enable hydrological modelling, and to assist in predicting the effects, if any, that underground mining may have on surface and ground water.

A metallurgical test work program is also progressing and while it is still at an early stage, results to date suggest that the process flow at the existing Waihi process plant will be suitable for WKP mill feed. Recoveries are indicated to be relatively consistent with other Waihi District underground resources.

Technical studies are progressing for the Waihi North Project regulatory approval package. The scope of the studies includes ecological impacts, visual effects, noise and vibration, dust, surface and subsurface water, traffic effects, economic benefits and impacts and potential mitigations. A community and stakeholder engagement program continues to progress well.
