OceanaGold Corporation (TSX: OGC; OTCQX: OCANF) (“OceanaGold” or the “Company”) - https://www.commodity-tv.com/ondemand/companies/profil/oceanagold-corp/ - is pleased to announce results from the ongoing exploration and resource conversion program at Wharekirauponga (WKP), located ~10 kilometres from the Waihi operation, New Zealand.
Highlight drill intercepts include (estimated true width):
Results Overview
Since the March 7, 2024 WKP news release, drilling has continued to intersect significant mineralization in all 11 holes on the East Graben (EG) vein and associated hanging-wall and foot-wall veins (EG vein system) in the high-grade southern zone (Table 1, Figures 1 and 2).
Extensional Drilling
In late March 2024, drill site 9 was commissioned which has enabled drilling of the southern strike extension of the EG vein system (Figure 1). Two holes (WKP134 and WKP132) were drilled from the new drill site. WKP134 tested up-dip of the southernmost hole across the EG vein and continues to demonstrate excellent vein width and grade, with further growth opportunities remaining up-dip and along-strike to the south on the structure. This result is ~200 metres away from the southern extent of the current resource (Figure 2).
There were 4 resource extension holes drilled from drill site 8 and a further 4 resource extension holes from drill site 1 (Figure 1), all of which intersected significant mineralization and demonstrate strong grade and structural continuity along strike of the existing resource (Figure 2, Table 1). Other opportunities remain for up-plunge, down-plunge, and along-strike extensions of the EG vein system with all intercepts remaining open to the south over a vertical window of approximately 200 metres. The EG vein system remains the primary, near-term drill target for the 2024 21-hole growth and conversion program, with the T-Stream and Western Vein targets offering similar growth potential and warrant future additional drilling (Figure 1).
Resource Conversion Drilling
Another resource conversion drillhole, WKP129A, was completed from drill site 1 and returned excellent results (9.9 g/t Au over 20.3 metres (true width) and 19.4 g/t Au over 7.1 metres (true width). This hole supports the model with significant grade and width, resulting in a ~150 metre strike of high-grade mineralization remaining open up-dip for further testing.
2024 Exploration Program
Exploration drilling for the remainder of the 2024 program will target resource growth from drill sites 8 and 9, testing beyond the current southern extent of drilling, and up-dip of both current and future extension holes in the south. The NI 43-101 pre-feasibility study, scheduled for release by the end of the year, will be based on an interim resource model with drillhole data as of the end of May 2024. Subsequent drill results will be captured in an end-of-year resource model update to be released with the 2024 Annual Reserve and Resource statement early next year.

About WKP and the Waihi North Project
The WKP low-sulphidation epithermal Au-Ag vein system is located approximately 10 kilometres north of the Company’s Waihi operation. The WKP Indicated Resource stands at 2.0 million tonnes grading 15.9 g/t Au for 1.01 million ounces of gold with a further 1.2 million tonnes grading 9.0 g/t Au for 0.35 million ounces of gold in the Inferred category as of December 31, 2023.
WKP is part of the Waihi North Project, which has the potential to create significant socio-economic contributions for the communities in the Waihi region and for New Zealand. This includes significant in-country investments and a substantial increase to direct and indirect employment opportunities, with the project having the potential to extend operation of the Waihi mine beyond the next decade. OceanaGold operates to the highest environmental and social standards which has enabled it to run a successful and responsible mining business in New Zealand for over three decades. The Company has lodged a resource consent application for its proposed Waihi North Project with Hauraki District Council and Waikato Regional Council and has also sought referral of the project to the proposed “fast-track” process.

Quality Assurance and Quality Control (QA/QC) at Wharekirauponga, Waihi Gold Mine
All exploration samples are assayed for gold by 30g fire assay with AAS finish. Since mid-2022 drill core sample intervals where visible electrum is logged are followed up by a subsequent screen fire assay after the routine 30g fire assay. Holes WKP40-45 had core samples shipped for sample preparation to SGS in Westport (New Zealand). Prepared pulps were then shipped to independent Australian Laboratory Services Pty Ltd (ALS) in Brisbane, accredited to ISO/NATA 17025 for gold analysis by fire assay and 4-acid digest, and 42 element ICP geochemical analysis. Holes drilled after WKP45 (i.e., WKP46 to WKP134) were prepared and analyzed at SGS Waihi NZ Ltd (Au by 30g fire assay and Ag by aqua regia digest and 0.3gm AAS finish). Selected pulps are periodically sent to ALS in Brisbane for a 4-acid digestion and 42 or 48 element ICP geochemical analysis.
Quality of exploration assay results has been monitored in the following areas:

Two holes (WKP134 and WKP132) were drilled from the new drill site. WKP134 tested up-dip of the southernmost hole across the EG vein and continues to demonstrate excellent vein width and grade, with further growth opportunities remaining up-dip and along-strike to the south on the structure. This result is ~200 metres away from the southern extent of the current resource (Figure 2).
There were 4 resource extension holes drilled from drill site 8 and a further 4 resource extension holes from drill site 1 (Figure 1), all of which intersected significant mineralization and demonstrate strong grade and structural continuity along strike of the existing resource (Figure 2, Table 1). Other opportunities remain for up-plunge, down-plunge, and along-strike extensions of the EG vein system with all intercepts remaining open to the south over a vertical window of approximately 200 metres. The EG vein system remains the primary, near-term drill target for the 2024 21-hole growth and conversion program, with the T-Stream and Western Vein targets offering similar growth potential and warrant future additional drilling (Figure 1).
Resource Conversion Drilling
Another resource conversion drillhole, WKP129A, was completed from drill site 1 and returned excellent results (9.9 g/t Au over 20.3 metres (true width) and 19.4 g/t Au over 7.1 metres (true width). This hole supports the model with significant grade and width, resulting in a ~150 metre strike of high-grade mineralization remaining open up-dip for further testing.
2024 Exploration Program
Exploration drilling for the remainder of the 2024 program will target resource growth from drill sites 8 and 9, testing beyond the current southern extent of drilling, and up-dip of both current and future extension holes in the south. The NI 43-101 pre-feasibility study, scheduled for release by the end of the year, will be based on an interim resource model with drillhole data as of the end of May 2024. Subsequent drill results will be captured in an end-of-year resource model update to be released with the 2024 Annual Reserve and Resource statement early next year.

Quality of exploration assay results has been monitored in the following areas:
- Sample preparation at the SGS Waihi and Westport labs through sieving of jaw crush and pulp products.
- Monitoring of assay precision through routine generation of duplicate samples from a second split of the jaw crush and calculation of the fundamental error.
- Monitoring of accuracy of the primary SGS assay and ALS results through insertion Certified Reference Materials (CRM’s) and blanks into sample batches.
