K92 Mining 公布 Arakompa 与 Wera 勘探进展：Arakompa 矿化带扩大，Wera 发现 3.5 公里见方矿化系统

不列颠哥伦比亚省温哥华，2025年9月11日（GLOBE NEWSWIRE）—— K92 Mining Inc （“ K92 ”或“ 公司 ”）（TSX ：KNT； OTCQX ：KNTNF） 欣然宣布其第五批钻探结果，包含24个钻孔，迄今已公布的总钻孔数为67个，来自其位于巴布亚新几内亚Arakompa的首次地表金刚石钻探计划，该地点距Kainantu金矿选矿厂约4.5公里。此外，K92欣然报告其位于Wera远景区首次绿地勘探计划的初步结果，勾勒出一个约3.5公里乘3.5公里的大型矿化系统，位于Kora和Judd矿床西南约10公里处。

• 钻孔KARDD0065从Arakompa最新结果向南外推约250米，发现了显著的斑岩型矿化，记录到690.4米、铜当量（“CuEq”）品位0.30%^（2）（金0.17克/吨、铜0.17%、银2克/吨），自297.0米起，其中包括395.3米、CuEq品位0.38%（金0.24克/吨、铜0.20%、银2克/吨），自349.7米起。该孔设计有两个目标：（i）测试Arakompa的走向延伸；以及（ii）作为首个钻孔测试600米×600米的土壤铜异常。相交矿化以浸染状硫化物形式出现，并存在脉体赋存和脉体控制的硫化物矿化。硫化物矿化以黄铜矿为主，也观察到少量斑铜矿和辉钼矿。还存在斑岩型B型、D型和M型石英硫化物脉。该相交段被解释为位于斑岩钾化核的远端，终孔于矿化中，并且是后续钻探的一个非常重要的指向，后续钻探正在进行中。
• Arakompa 大吨位矿化带的走向延伸范围在北部和南部均显著扩大，目前该大吨位矿化带已圈定走向长度约 1,100 米、垂深 800 米，较 2025 年 2 月 20 日新闻稿分别增加走向 200 米、深度 150 米。迄今为止的钻探结果记录到平均真厚度 39 米，凸显出强劲的近地表大吨位开采潜力（见 2025 年 2 月 20 日 新闻稿）。迄今为止的钻探结果记录到平均真厚度 39 米，凸显出强劲的近地表大吨位开采潜力（见 图 5 – Arakompa 大吨位解释纵剖面图） 。解释的大吨位矿化带由围绕高品位矿脉的厚大、强烈蚀变矿化晕组成，且在多个方向上仍保持开放。

• 首次绿地勘探计划最初聚焦于 Wera 的岩屑和槽探，已圈定出一个约 3.5 公里 × 约 3.5 公里的大型低硫化浅成低温热液金矿系统，位于 Kora 和 Judd 矿床西南约 10 公里处，其中有多条推断的矿化构造和高品位岩屑样品，包括 26.30 g/t Au、25.06 g/t Au、23.97 g/t Au、22.06 g/t Au、19.69 g/t Au、19.23 g/t Au、18.40 g/t Au、18.40 g/t Au、18.03 g/t Au、16.05 g/t Au、13.83 g/t Au、11.09 g/t Au、10.88 g/t Au 和 10.21 g/t Au（见图 8 Wera 平面图）。重要的是，该区域此前业主未曾进入或测试，且位于赋存 Kora、Judd 和 Arakompa 矿床的主要北北东向区域矿化构造走廊内。钻探正在进行中。

备注：

(1) 上文所列钻探亮点为核心长度（非真厚度）。
(2) 金当量（AuEq）和铜当量（CuEq）勘探结果采用长期大宗商品价格计算，其中铜价为4.50美元/磅，银价为27.5美元/盎司，金价为2,000美元/盎司。 对于AuEq，按更新后的最终可行性研究采用了以下回收率：Au – 92.6%，Cu – 94.0%，以及Ag – 78.0%。对于CuEq，未考虑冶金回收率和净冶炼厂收益。

K92首席执行官兼董事John Lewins表示， “我们对最新区域勘探成果取得的进展极为满意，在Arakompa探获多个高品位见矿段，显著扩大了块状矿带，并在首个深部钻孔中于600米×600米的土壤铜异常范围内发现了一个潜在的斑岩体。我们在Wera的首次绿地野外工作中发现了一个3.5公里×3.5公里的大型矿化系统，这也造就了又一个规模可观、目标丰富的勘探区域，而且距离Kora仅10公里。

这些新发现恰逢两台新的地表金刚石钻机按计划于2026年第四季度末/第一季度初交付。新增的钻探能力将支持我们在未来两年乃至可能更长时间内大幅加大勘探力度的战略。针对潜在斑岩体的第二个钻孔现已开钻，此外，我们还引入了一台承包商钻机以扩充机队，并已在Wera开始钻探。我们期待在适当时候提供最新进展。”

K92勘探副总裁Robert Smillie表示：“ 随着我们向首个矿产资源量推进，Arakompa持续的勘探成功令我们非常振奋。迄今为止，钻探仅测试了Arakompa走廊超过2公里走向长度的一半多一点，而KARDD0065孔的最新钻探结果所显示的南部斑岩潜力令我们深受鼓舞。KARDD0065孔以南的后续钻探正在进行中，旨在指向该系统潜在的高品位钾化核心。

此外，在获得高品位岩屑和探槽样品后，我们正开始对Wera新发现的大型矿化脉系统进行钻探测试，该系统沿走向两个方向均未封闭。K92勘探团队这一新的绿地发现潜力令我们振奋，矿化走廊已展现的区域找矿前景也提供了支持，该走廊还赋存Kora、Judd和Arakompa矿床。 ”

Arakompa 矿脉系统背景

Arakompa 项目被解释为一个与侵入岩有关的金-铜-银浅成低温热液脉系统，与正在生产的 Kora 和 Judd 脉系统具有相似性。Arakompa 的一个显著不同之处在于，其赋存于英云闪长岩至闪长岩类岩石中，而 Kora 和 Judd 主要赋存于变沉积岩（千枚岩）中。

Arakompa 的矿化赋存于显著的脉状矿体中，但也广泛分布于一个非常宽阔的包络范围内，容矿岩石为强烈蚀变的英云闪长岩和闪长岩。这被解释为泥化蚀变和高级泥化蚀变塌陷的结果，而基底英云闪长岩的青磐岩化蚀变则被解释为源自大型岩浆斑岩体的侵入。绢英岩化蚀变似乎与金矿化有关，在脉体走廊周围形成了一个大型晕圈（至少 100 米宽）。绢英岩化蚀变很可能从斑岩体向上涌入围岩中的高品位脉体。这导致了脉体之间的矿化，为大规模采矿提供了潜力。

矿脉内部本身可见多阶段成矿事件，伴有多个阶段的石英-硫化物发育。在Arakompa，早期石英从中温稀流体中沉积，随后发生黄铁矿-铜-金±Bi-Te-Pb-Zn-Sn矿化，这一序列与在Kora和Judd所见的相同事件有许多相似之处。

主要硫化物为黄铁矿、黄铜矿、斑铜矿和辉铋矿。与Kora一样，黄铜矿形成较晚，叠加在早期黄铁矿之上。岩石学报告记录了金，显微照片显示金赋存于石英中，或常以包裹体形式被黄铜矿增生包裹。

在Arakompa广泛存在斑岩型矿化的证据。可见局部的高位B型脉（石英脉中含中心线状黄铁矿），这是斑岩系统上部的典型特征。磁铁矿-绿帘石蚀变代表典型的进变质斑岩矿物组合，指示内青磐岩化带。局部还可见辉铜矿，暗示深部存在富铜矿体。

历史上以及由K92完成的露天野外工作已表明，Arakompa的目标规模相当可观，从钻孔、岩石样品和露天采场中观察到的矿化至少沿走向延伸2.0公里，赋存于约400米宽的强绢英岩化蚀变矿化带内，垂向延伸超过800米。

Wera 矿脉系统背景

Wera项目被解释为一个含金低硫化浅成热液系统，赋存于闪长岩-英云闪长岩侵入体中。该项目可通过公路到达，位于Kora西南约10公里处。

K92 Mining 根据移动 MT 测量结果和对历史勘探数据的审查，将 Wera 确定为目标区域。实地项目于 2024 年 7 月启动，包括地质填图、岩屑采样、土壤采样和槽探。

Wera 的矿化赋存于石英脉中，呈现典型的低硫化浅成低温热液结构。蚀变基本局限于脉体周围的狭窄晕圈，以绢英岩化和硅化组合为主。岩屑、土壤和槽探样品已返回砷、锑、铊、钼和钨的异常水平，这些指示元素通常见于低硫化系统的上部层位。

目前一项勘探金刚石钻探计划正在进行中。这标志着Wera的首次大型钻探活动，旨在测试近地表推断的矿脉系统，并提供关键信息以指导后续更深部的钻探。

Drill Hole Sampling Methodology, QA/QC and Qualified Person

The diamond drill hole is first logged to determine the sampling intervals, which range from a minimum of 0.1 metres to generally 1 metre. The drill core is sawn half core cut along a reference line, with the remainder of the core returned to the core tray. Core samples are then placed in numbered calico and plastic bags, with a numbered sample ticket for dispatch to the assay laboratory. Samples are separately assayed for gold, copper and silver. K92’s procedure includes the insertion standards, blanks and duplicates. Gold assays are by the fire assay method. Copper and silver assays are by three-acid-digestion method (nitric, perchloric and hydrochloric mix).

K92 maintains an industry-standard analytical quality assurance and quality control (QA/QC) and data verification program to monitor laboratory performance and ensure high quality assays. Results from this program confirm reliability of the assay results. All sampling and analytical work for the mine exploration program is performed by Intertek Testing Services (PNG) Ltd, an independent accredited laboratory that is located on site. External check assays for QA/QC purposes are performed at SGS Australia Pty Ltd in Townsville, Queensland, Australia.

K92 Mining Chief Geologist, Andrew Kohler, PGeo, MAIG, Qualified Person under the meaning of National Instrument 43-101 – Standards of Disclosure for Mineral Projects , has reviewed and is responsible for the technical content of this news release. In addition to the analytical QA/QC program outlined above, data verification also includes significant time onsite reviewing drill core, soil and outcrop sampling, artisanal workings, as well as discussing work programs and results with geology personnel and external consultants.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION:
This news release includes certain “forward-looking statements” under applicable Canadian securities legislation. Such forward-looking statements include, without limitation: (i) the results of the Kainantu Mine Definitive Feasibility Study, including the Stage 3 Expansion, a new standalone 1.2 mtpa process plant and supporting infrastructure; (ii) statements regarding the expansion of the mine and development of any of the deposits; (iii) the Kainantu Stage 4 Expansion, operating two standalone process plants, larger surface infrastructure and mining throughputs; and (iv) the potential extended life of the Kainantu Mine.

All statements in this news release that address events or developments that we expect to occur in the future are forward-looking statements. Forward-looking statements are statements that are not historical facts and are generally, although not always, identified by words such as “expect”, “plan”, “anticipate”, “project”, “target”, “potential”, “schedule”, “forecast”, “budget”, “estimate”, “intend” or “believe” and similar expressions or their negative connotations, or that events or conditions “will”, “would”, “may”, “could”, “should” or “might” occur. All such forward-looking statements are based on the opinions and estimates of management as of the date such statements are made. Forward-looking statements are necessarily based on estimates and assumptions that are inherently subject to known and unknown risks, uncertainties and other factors, many of which are beyond our ability to control, that may cause our actual results, level of activity, performance or achievements to be materially different from those expressed or implied by such forward-looking information. Such factors include, without limitation, Public Health Crises, including the epidemic or pandemic viruses; changes in the price of gold, silver, copper and other metals in the world markets; fluctuations in the price and availability of infrastructure and energy and other commodities; fluctuations in foreign currency exchange rates; volatility in price of our common shares; inherent risks associated with the mining industry, including problems related to weather and climate in remote areas in which certain of the Company’s operations are located; failure to achieve production, cost and other estimates; risks and uncertainties associated with exploration and development; uncertainties relating to estimates of mineral resources including uncertainty that mineral resources may never be converted into mineral reserves; the Company’s ability to carry on current and future operations, including development and exploration activities at the Arakompa, Kora, Judd and other projects; the timing, extent, duration and economic viability of such operations, including any mineral resources or reserves identified thereby; the accuracy and reliability of estimates, projections, forecasts, studies and assessments; the Company’s ability to meet or achieve estimates, projections and forecasts; the availability and cost of inputs; the availability and costs of achieving the Stage 3 Expansion or the Stage 4 Expansion; the ability of the Company to achieve the inputs the price and market for outputs, including gold, silver and copper; failures of information systems or information security threats; political, economic and other risks associated with the Company’s foreign operations; geopolitical events and other uncertainties, such as the conflicts in Ukraine, Israel and Palestine; compliance with various laws and regulatory requirements to which the Company is subject to, including taxation; the ability to obtain timely financing on reasonable terms when required; the current and future social, economic and political conditions, including relationship with the communities in Papua New Guinea and other jurisdictions it operates; other assumptions and factors generally associated with the mining industry; and the risks, uncertainties and other factors referred to in the Company’s Annual Information Form under the heading “Risk Factors.”

Estimates of mineral resources are also forward-looking statements because they constitute projections, based on certain estimates and assumptions, regarding the amount of minerals that may be encountered in the future and/or the anticipated economics of production. The estimation of mineral resources and mineral reserves is inherently uncertain and involves subjective judgments about many relevant factors. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The accuracy of any such estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation, Forward-looking statements are not a guarantee of future performance, and actual results and future events could materially differ from those anticipated in such statements. Although we have attempted to identify important factors that could cause actual results to differ materially from those contained in the forward-looking statements, there may be other factors that cause actual results to differ materially from those that are anticipated, estimated, or intended. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. The Company disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.
