Western Alaska Minerals Refines Exploration Model Yielding System-Wide Targeting at Illinois Creek

Western Alaska Minerals Refines Exploration Model Yielding System-Wide Targeting at Illinois Creek

阿拉斯加西部矿业公司完善勘探模型,在伊利诺伊河实现全系统目标
Accesswire ·  2023/12/07 07:30

TUCSON, AZ / ACCESSWIRE / December 7, 2023 / Western Alaska Minerals (the "Company" or "WAM") (TSX-V:WAM) is pleased to provide an exploration summary for 2023 work completed on its 100% owned, 30,000-hectare Illinois Creek ("IC") Carbonate Replacement Deposit ("CRD") project in central Alaska.

亚利桑那州图森/ACCESSWIRE/2023年12月7日/西阿拉斯加矿业(“公司” 或 “WAM”)(TSX-V: WAM)很高兴提供2023年阿拉斯加中部100%自有的、占地3万公顷的伊利诺伊溪(“IC”)碳酸盐替代矿床(“CRD”)项目完成工作的勘探摘要。

The project hosts a continuous six-kilometer corridor of CRD-style alteration, favorable structure, and permissive stratigraphy linking the past-producing gold-silver Illinois Creek Mine ("ICM") in the southwest and the high-grade silver-lead-zinc Waterpump Creek ("WPC") massive sulfide CRD deposit in the northeast (Figure 1).

该项目拥有一条长达六公里的连续走廊,包括CRD式的改动、良好的结构和宽松的地层结构,连接了西南过去生产金银的伊利诺伊溪矿山(“ICM”)和东北部的高品位银铅锌水泵溪(“WPC”)块状硫化物CRD矿床(图1)。

The 2023 drilling season dedicated 5 holes totaling 1,706 meters to expand the high-grade sulfide mineralization at Waterpump Creek and 3,412 meters in 9 holes to seek mineralization 700 meters to the south across a post-mineral fault into the Last Hurrah target area where geophysics, surface sampling, and historical drilling indicated the mineralized corridor runs.

2023年的钻探季节专门开了5个总长1706米的钻孔来扩大Waterpump Creek的高品位硫化物矿化,并在9个孔中专门开了3,412米,用于向南700米处穿过后矿化断层进入最后一刻的目标区域,地球物理学、地表采样和历史钻探表明矿化走廊在运行。

Waterpump Creek drilling extended massive sulfide mineralization at least 45 meters down-plunge to the south and demonstrates lateral continuity of the mineralization for 495 meters to where the body is apparently displaced by an ENE-WSW trending fault. The best hole in 2023 was WPC23-30, ( See press release dated August 14 ) which cut 40.2 meters core width (37.8 meters true width) of 262 g/t Ag (8.4 opt), 10.9% Pb and 4.5% Zn, including: 5.3 m of 729 g/t Ag (23.4 opt), 24.1% Pb and 3.1 % Zn, and 8.6 m of 493 g/t Ag (15.8 opt), 22.9% Pb and 2.6% Zn. Drilling then moved to Last Hurrah, testing the continuation of WPC mineralization across the post-mineral fault. The drill holes there yielded broad zones of CRD alteration with dispersed mineralization, which correlate well with 2005 and 2023 geophysical models. More importantly, 2 of the 3 Last Hurrah holes that were drilled through an underlying impermeable schist, hit similar alteration in a limestone unit. This indicates that mineralization may also occur in this deeper unit, opening it for exploration across the property (Figures 1-3). The technical team is integrating these results into an enhanced district model, including reinterpretation of the geophysics, in preparation for drilling next season.

Waterpump Creek 钻探将大量硫化物矿化向南延伸了至少 45 米,并证明了矿化的横向连续性 495 米,到矿体显然被 ENE-WSW 倾向断层移位的地方。2023 年最好的钻孔是 WPC23-30,(参见 8 月 14 日的新闻稿),它切割了 40.2 米的岩芯宽度(真实宽度 37.8 米),即 262 克/吨银(8.4 选项)、10.9% 的铅和 4.5% 的锌,包括:5.3 m 的 729 g/t Ag(23.4 opt)、24.1% 的铅和 3.1% 的锌,以及 8.6 m 的 493 g/t Ag(15.8 选项),22.9% Pb 和 2.6% 的锌。钻探随后移至最后一刻,测试了矿后断层中木塑矿化的持续性。那里的钻孔产生了广阔的CRD蚀变区域,矿化层分散,这与2005年和2023年的地球物理模型密切相关。更重要的是,在底层不透水片岩中钻出的3个Last Hurrah洞中,有2个在石灰石单元中遇到了类似的变化。这表明矿化也可能发生在这个更深的单元中,从而为整个物业的勘探敞开了大门(图 1-3)。技术团队正在将这些结果整合到增强的区域模型中,包括对地球物理学的重新解释,为下个季节的钻探做准备。

"It is rare for a junior exploration company to control, in a stable mining jurisdiction, an entire, intact system of this scale, that even at this early stage is showing the hallmarks of a well-mineralized CRD system, " stated CEO Kit Marrs. " It took several tries with the drill bit at WPC, but once we intercepted the exceptionally high-grade silver-lead-zinc sulfides there, it took just two seasons of drilling to flesh out a substantial zone, justifying the calculation of an initial mineral resource estimate. Results to date suggest that WPC is just the fingertip of a 6 km-long mineralized trend that runs back to Illinois Creek, of which only 8% has been drill tested to date. With our updated understanding of the system, we are excited to be zeroing in at Last Hurrah and continuing to trace high-grade mineralization back towards Illinois Creek."

在稳定的采矿管辖区,初级勘探公司很少能控制如此规模的完好无损的完整系统,即使在这么早的阶段,也显示出矿化良好的CRD系统的特征, “首席执行官基特·马尔斯说。“ 在WPC的钻头上花了好几次尝试,但一旦我们在那里截获了极高品位的银铅锌硫化物,仅用了两个季节的钻探就充实了一个大片区域,这证明了计算初步矿产资源估算的合理性。迄今为止的结果表明,木塑只是延伸到伊利诺伊河的长达6千米的矿化趋势的指尖,迄今为止,只有8%的矿化趋势经过了钻探测试。凭借我们对该系统的最新了解,我们很高兴能够集中精力,继续追踪伊利诺伊河的高品位矿化。”

Key Takeaways

关键要点

  • In-fill and additional high-grade intercepts from step-out drilling at Waterpump Creek were completed, adding 45 meters to the mineralization trend, allowing for an initial NI 43-101 complaint resource estimate, anticipated in Q1 2024.
  • Exploration drilling at Last Hurrah yielded strong CRD alteration which correlates with both the 2005 and 2023 modelled geophysics (Figures 1,3, and 4). More importantly, the alteration and anomalous geochemistry occur in two separate stratigraphic units, effectively doubling the exploration potential.
  • The 2023 and prior drilling results now indicate that three carbonate units exist, separated by impermeable or unreactive units, and a progressive southwesterly shift of mineralization focus from the uppermost carbonate at WPC, through the middle unit at LH and the deepest known unit at Illinois Creek (Figure 2).
  • This new geologic recognition, combined with advanced remodeling of the eleven square-kilometer high-resolution 3D geophysical survey covering both WPC and Last Hurrah, is helping to determine the structural and stratigraphic controls on mineralizing fluid migration from the probable porphyry source near the Illinois Creek Mine, through Last Hurrah to WPC (Figure 3).
  • 在 Waterpump Creek 跨步钻探产生的填充和额外的高品位截获物已经完成,矿化趋势增加了45米,因此预计将在2024年第一季度对NI 43-101投诉资源进行初步估算。
  • Last Hurrah的勘探钻探产生了强烈的CRD变化,这与2005年和2023年建模的地球物理学相关(图1,3和4)。更重要的是,蚀变和异常地球化学发生在两个独立的地层单元中,这实际上使勘探潜力翻了一番。
  • 现在,2023年和之前的钻探结果表明,存在三个碳酸盐单元,由不渗透或非反应单元隔开,矿化重点逐渐从WPC最上方的碳酸盐向西南移动,穿过LH的中间单元和伊利诺伊河的已知最深单元(图2)。
  • 这种新的地质认识,加上对涵盖WPC和Last Hurrah的11平方千米高分辨率三维地球物理调查的高级重建,有助于确定矿化流体从伊利诺伊州溪矿附近可能的斑岩源向WPC迁移的结构和地层控制(图3)。

The Company believes that CRD-style mineralization and alteration is continuous and increasing in intensity and scale to the south and west. This correlates well with the district zonation pattern which ranges from distal low temperature silver-zinc-lead mineralization at WPC to proximal higher temperature copper-gold-silver at IC as is expected in CRD systems.

该公司认为,CRD式的矿化和蚀变是持续的,向南和向西的强度和规模都在增加。这与区域分区模式密切相关,区域分区模式从木塑复合材料的远端低温银锌铅矿化到近端高温的铜金银矿化,如CRD系统所预期的那样。

This progressive metal zonation from Au-Ag-Cu at the Illinois Creek deposit to high grade Ag-Pb-Zn at WPC with alteration and mineralization occurring in multiple and progressively higher structural/stratigraphic "Stair Step" levels (Figure 2) demonstrates the excellent potential of the Illinois Creek District as a large scale CRD system.

这种渐进的金属分区从伊利诺伊河矿床的金银铜到木塑的高品位银铅锌,其蚀变和矿化发生在多个且逐渐提高的结构/地层 “阶梯” 层级(图 2)中,显示了伊利诺伊州溪区作为大规模 CRD 系统的巨大潜力。

"Continuity of mineralization from the source outward with gradually diminishing volume, often over several kilometers, has been recognized for over 100 years as a fundamental aspect of CRD systems, so it is highly probable we'll find the continuation of Waterpump Creek mineralization across the post-mineral fault," said Dr. Peter Megaw, Exploration Advisor to WAM. "Importantly, many CRD systems show "Christmas Tree" patterns of mineralization affecting more and more layers in the stratigraphy as the source is approached and it looks like we're beginning to see that progression at Last Hurrah".

WAM勘探顾问Peter Megaw博士说:“100多年来,从源头向外延续矿化,体积逐渐减少,通常超过几千米,一直被认为是CRD系统的基本方面,因此我们很可能会发现Waterpump Creek矿化在矿物后断层中持续存在。”“重要的是,许多CRD系统显示出 “圣诞树” 的矿化模式,随着来源的临近,会影响地层中越来越多的层,看来我们在最后一刻开始看到这种进展”。

Last Hurrah Drilling (Phase II)

最后一轮钻探(第二阶段)

  • 2023 exploration drilling in this new zone showed strong and abundant CRD alteration, characterized by broad CRD-style surrounding "fugitive" carbonate veins, in nearly all drill holes. The modelled resistivity from the 2023 survey suggests that the alteration increases in size to the south and west of Last Hurrah towards the Illinois Creek mine.
  • Anomalous Pb and Zn values coincide with the CRD alteration, however, no massive sulfides were intersected.
  • BBQ rock" (UV fluorescent fugitive calcite) remains a key proximity vector to mineralization and was intersected in all but 2 Last Hurrah holes ( See Press Release of August 14 , 2023).
  • The drilling and geophysical modelling at Last Hurrah shows conclusively that there are three key permissive CRD host rock stratigraphic units present and that mineralization seems to "stair-step" progressively from one to the other across the property from WPC to: Last Hurrah, Warm Springs Creek, and the Illinois Creek zone.
  • 2023 年在这个新区域的勘探钻探几乎在所有钻孔中都显示出强烈而丰富的CRD变化,其特点是围绕 “逃逸性” 碳酸盐矿脉的宽阔CRD型。2023年调查的建模电阻率表明,Last Hurrah以南和以西向伊利诺伊州溪矿的变化规模有所增加。
  • 异常的铅和锌值与CRD变化相吻合,但是,没有大量硫化物相交。
  • BBQ rock”(紫外线荧光散逸性方解石)仍然是矿化的关键邻近载体,除最后两个洞外,其他所有洞都与之相交(见2023年8月14日的新闻稿)。
  • Last Hurrah的钻探和地球物理建模最终表明,存在三个关键的允许CRD宿主岩地层单元,而且矿化似乎在从WPC逐渐从一个 “阶梯” 到另一个地产:Last Hurrah、Warm Springs Creek和Illinois Creek地带。

图 4. 从 Dias 3D DCIP 测量和反演中看到的 25 和 5 欧姆米等离子表面以东的三维视图。

A high-resolution 3-D resistivity and induced polarization survey ("3D IP") covering Waterpump Creek and Last Hurrah target areas was conducted by DIAS Geophysical during the summer field season. Inversion modeling reveals distinct structural, stratigraphic controls to CRD mineralization and outlines the increasing alteration halo to the south. Figure 4 above shows the modeled 25 ohm-m zone, which can be used as a proxy for alteration and the 5 ohm-meter zones that show district breaks that define syn- and post-mineralization structures.

DIAS Geophysical在夏季野外活动季节进行了覆盖Waterpump Creek和Last Hurrah目标区域的高分辨率三维电阻率和感应极化测量(“3D IP”)。反演建模揭示了对CRD矿化的不同结构和地层控制,并概述了南方不断增加的蚀变光环。上面的图 4 显示了建模后的 25 欧姆-m 区域,该区域可用作变化代理,以及 5 欧姆表区域,显示了定义同步和矿化后结构的区域间隔。

  • Detailed inversion modeling defines the fault structures that offset the WPC mineralization and the (likely) vertical north-south fault(s) that control the CRD mineralizing fluids.
  • Importantly, the resistivity modeling shows a <25 ohm-meter signature that corresponds directly with extensive sanding and clay alteration surrounding the CRD mineralization.
  • The IP modeling, in tandem with the drilling in WPC and Last Hurrah also shows an increasing scale in alteration to the south that extends through all three permissive carbonate horizons.
  • 详细的反演建模定义了抵消 WPC 矿化的断层结构以及控制 CRD 矿化流体的(可能的)垂直南北断层。
  • 重要的是,电阻率建模显示出
  • IP建模以及WPC和Last Hurrah的钻探还显示,向南的变化规模越来越大,延伸到所有三个允许的碳酸盐地平线。
