OceanaGold 公布 Wharekirauponga 高品位钻探结果，Waihi North 项目获初步批准意向

，/CNW/ — OceanaGold Corporation（TSX: OGC）（OTCQX: OCANF）（“OceanaGold”或​“公司”）公布了Wharekirauponga正在进行的勘探与资源转换计划的十个钻孔结果，该地点位于公司位于新西兰的Waihi运营区以北约10公里（“km”）处。

OceanaGold 还欣然宣布，2025年11月25日，新西兰政府为审议 Waihi North Project（“WNP”）依据《快速审批法》的许可事宜而任命的专家小组发布了一份决定草案及条件，表明其暂定有意批准该项目。该决定草案及条件仍需经过进一步的评论期，最终决定预计将在2025年年底前作出。

Wharekirauponga 钻探亮点（估算真实宽度）：

• 13.9 米 @ 25.8 克/吨金，自 466.8 米，EG 矿脉（WKP137A）
• 7.4 米 @ 5.3 克/吨金，自 396.0 米，EG HWS 矿脉（WKP137A）
• 1.8 米 @ 108.1 克/吨金，自 514.7 米起，EG矿脉（WKP124J）
• 2.5 米 @ 17.0 克/吨金，自 530.3 米，EG FW 矿脉（WKP124J）
• 3.2 米 @ 19.7 克/吨金，自 532.6 米 起，EG 矿脉（WKP124K）
• 1.5 米 @ 28.8 克/吨金，自 474.4 米，EG HW 矿脉（WKP124K）
• 5.6 米 @ 6.9 克/吨金，自 534.2 米起，EG矿脉（WKP124L）

Gerard Bond，OceanaGold 总裁兼首席执行官表示：​“我们对 Wharekirauponga 今日公布的钻探结果感到振奋，这些结果将高品位矿化延伸至资源南部边界，WKP137A 钻孔获得的极佳高品位见矿段便是明证。随着更多后续钻探工作的规划，我对我们通过勘探持续实现的价值和投资回报感到非常满意，因为该矿床仍在继续扩大。”

专家小组发布了决定草案和条件，表明有意依据快速审批法案（Fast-track Approvals Act）临时批准 Waihi North 项目，我们对此也感到鼓舞。我们期待继续与审批流程的参与方保持沟通，并推进申请的下一个阶段，争取在今年年底前获得最终决定。我们打算安全、负责任地开发 Waihi North 项目，该项目将把 Waihi 矿山的开采寿命大幅延长至未来，同时为我们的股东带来强劲回报，并为当地社区和 新西兰 带来更广泛的经济效益。”

Wharekirauponga 钻探结果概览

东地堑（“EG”）矿脉

自2025年6月25日新闻稿发布以来，共完成十个钻孔，并已收到EG矿脉、上盘（“HW”）矿脉和下盘（“FW”）矿脉的化验结果，这些矿脉统称为​“EG矿脉带”（图1）。钻探结果进一步将矿化EG矿脉的已知边界向南（界定）延伸了135 米，并提高了对资源（转化）潜力的信心。这些结果继续表明，EG矿脉带相关矿产资源具有显著的扩展潜力。

在 9 号钻探场地的钻探中，WKP137A 见矿段（13.9 m，金品位 25.8 g/t）为高品位 EG 矿脉，延伸了资源南端的高品位矿化。该结果得到此前见矿段的支持：WKP135（6.3 m，金品位 8.7 g/t，发布于 2025 年 3 月）、WKP137（4.0 m，金品位 43.8 g/t，发布于 2025 年 6 月）和 WKP134A（7.7 m，金品位 11.4 g/t，发布于 2024 年 11 月），这些见矿段在现有资源南边界圈定出一个新的高品位带，该高品位带向南仍保持开放，具有显著的增长潜力。

To further test this, step out hole WKP140A at the southern-most trace of drilling returned an intercept of 2.6 m @ 0.6 g/​t, confirming the continuation of the EG vein 135 m to the south of previously reported hole WKP139 (2.9 m @ 0.5 g/​t Au, released June 2025). The continuity of veining demonstrated by WKP140A supports growth of the total known strike length from 1.4 km to 1.5 km and this remains open to the north and south. 

钻探点 1 的结果包括 WKP143，该孔沿 EG 脉向下倾方向完成，返回 2.3 m @ 4.6 g/t Au，与相邻钻孔相似，延伸了矿化。

At drill site 8, five new directional holes have been completed from the WKP124 parent hole, which have infilled and tested the extents of the mineralization on the EG vein structure. Conversion drilling highlights include the high-grade intersection received in hole WKP124J with 1.8 m @ 108.1 g/​t Au (EG vein). Drill hole intersections across the EG vein in holes WKP124K (3.2 m @ 19.7 g/​t Au) and WKP124L (5.6 m @ 6.9 g/​t Au) met expectations and increased resource confidence. Drill holes WKP124H (NSR) and WKP124I (NSR) defined the upper limit of the EG vein at this location (Figure 2). 

上盘与下盘矿脉

值得注意的是，分别紧邻 EG 矿脉带东侧和西侧的 HW 与 FW 矿脉构造同样取得了强劲成果。钻孔 WKP137A 在 EG 上盘分支（“HWS”）返回 7.4 m @ 5.3 g/​t Au 的见矿段，这延伸了该构造上的已知矿化，与 EG 矿脉的延伸部分平行，其他此前报告的周边见矿段包括 WKP135（1.7 m @ 24.6 g/​t Au，发布于 2025 年 3 月）、WKP134A（2.3 m @ 16.0 g/​t Au，发布于 2025 年 3 月）和 WKP137（5.9 m @ 14.7 g/​t Au，发布于 2025 年 6 月）（图 3）。

High-grade Au was intersected across several other EG HW and FW structures including 2.5 m @ 17.0 g/​t Au and 2.4 m @ 10.4 g/​t Au from separate FW veins in drill hole WKP124J and 1.5 m @ 28.8 g/​t Au from a HW vein in WKP124K, continuing to demonstrate the potential for additional resource growth at Wharekirauponga outside of the main EG vein structure.

Wharekirauponga 勘探项目

Exploration for the remainder of the 2025 program will continue to target resource growth on the EG vein zone from drill sites 8 and 9. In October, the Company received permits for two additional exploration drill sites. The Fast-track application includes a further increase in the number of exploration drill sites, expanding the program by 8 new sites (inclusive of two new sites added in October), as well as doubling the drilling effort, with up to 6 rigs operating at any one time, from the currently permitted 3 rigs. The doubling of the exploration drill sites and drill rigs will further accelerate both definition and conversion drilling at Wharekirauponga in 2026 and beyond.

Waihi North项目快速审批及前期工程活动更新

OceanaGold 对专家小组发布的一项草案决定及条件感到鼓舞，该草案表明其暂时有意通过《快速审批法》为 WNP 授予批准。需要注意的是，现阶段尚未作出最终决定。

专家小组现将就拟议的同意条件征求相关方的意见。随后，公司将有机会审阅这些意见并作出回应。

The Expert Panel’s final decision on the application is expected in mid-December 2025.

The Company also continues to advance early works, design and project activities at WNP, including construction of the services trench and expansion of the water treatment plant, and expects to spend $45 million in capital in 2025 on these activities. The construction of the 5 km services trench that will convey power, water and communications from the existing Waihi operations to the Willows surface facilities area commenced in the third quarter of 2025. Civil works and fabrication have also commenced at the expanded water treatment plant site and are progressing well, with both deliverables planned for completion by the second quarter of 2026.

质量保证与质量控制（“QA/QC”）

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. Core samples 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. Samples post April 2024 with Ag, As, Sb. Hg and S by ICP-MS after DIG12R Digest). Selected pulps are periodically sent to ALS in Brisbane for a 4‑acid digestion and 42 or 48 element ICP geochemical analysis. 

以下领域的勘探化验结果质量已受到监控： 

• 在SGS Waihi和Westport实验室通过筛分颚式破碎和矿浆产品进行样品制备；
• 通过常规从颚式破碎的第二份缩分样中生成副样并计算基本误差，来监测化验精密度；以及
• 通过在样品批次中插入标准物质（“CRMs”）和空白样，对SGS主化验和ALS结果的准确性进行监控。 

空白样、重复样和CRM结果在将结果上传至AcQuire数据库之前进行审核，并每周再次审核。Waihi的方案要求CRM报告值处于认证值2个标准偏差以内。制备重复样的标准是其相对差异（R‑R1/​mean RR1）不大于10%。空白样不应超过测定方法检出下限的4倍。任何这些阈值未达标都会触发调查，并在适当情况下重新测定。钻探岩心储存在现场受控进入的安全设施内。现场员工将样品运送至分析实验室，该实验室同样是安全设施。SGS Waihi NZ Ltd实验室是一家独立的商业地球化学和能源分析实验室，拥有ISO 17025: 2017认证，于2020年由外部顾问审计，并由OceanaGold地质学家每季度检查一次。这些访问期间未记录到任何取样风险。
