Vancouver, British Columbia--(Newsfile Corp. - August 16, 2022) - Angold Resources Ltd. (TSXV: AAU) (FSE: 13L) (OTCQB: AAUGF) ("Angold" or the "Company") is pleased to provide an update of drilling at its Iron Butte Project, located approximately 60 km south of Battle Mountain, Nevada.

温哥华,不列颠哥伦比亚省-(Newsfile Corp.-2022年8月16日)-安金资源有限公司 (多伦多证券交易所:AAU)(证券交易所:13L)(OTCQB:AAUGF)("安金“或”公司“)很高兴提供其位于内华达州巴特山以南约60公里的铁巴特项目的最新钻探情况。

Drilling Highlights

钻探亮点

  • Drillhole AAU22-001 was stopped at 273 metres (894.5') depth due to lost tooling, and has been redrilled as AAU22-001A, as PQ-HQ core;
  • In hole AAU22-001A, the Company drilled into a shear zone, hosted by dolomitic and siliceous siltstone, with pyrite and carbon, some fine quartz veinlets and continued within Carlin-style alteration (decalcification and dolomitization) at the proposed termination depth of 670 metres (2,200');
  • AAU22-001A was continued with a reduction to NQ core to a termination depth of 710 metres (2,329');
  • Alteration at the TD of 710 metres (2,329') remains open;
  • Core samples from AAU22-001 and AAU22-001A await assay results;
  • The Company will complete the planned 2,926 metre (9,600') drill program with a TH-75 reverse circulation ("RC") drill rig that will be deployed to site shortly, and meets the Company's requirement to drill up to 1,000 metres from surface.
  • AAU22-001号井因工具丢失在273m(894.5‘)深度停钻,重新钻成AAU22-001A型井,为PQ-HQ岩心;
  • 在AAU22-001A孔,公司钻进了以白云岩和硅质粉砂岩为主体的剪切带,含黄铁矿和碳,以及一些细小的石英细脉,并继续在卡林式蚀变(脱钙和白云石化)内继续进行,拟议终止深度为670米(2,200‘);
  • 继续AAU22-001a,将NQ岩心的终端深度减少到710米(2329‘);
  • 运输署710米(2,329‘)的改建工程仍在进行中;
  • AAU22-001和AAU22-001a的岩心样品等待检测结果;
  • 公司将使用TH-75型反循环(RC)钻机完成计划中的2926米(9600‘)钻探计划,不久将部署到现场,满足公司在离地面1000米处进行钻探的要求。

Adrian Rothwell, President & Chief Executive Officer, said, "Despite difficult drilling in broken ground, drilling has indicated the potential presence of significant alteration in targeted geophysical and fault structures, in a geological setting never before tested and with surprisingly positive results at the planned termination of our first hole at ~2,200'. We are cautiously optimistic for assay results, which we expect in the next few weeks."

总裁&首席执行官禤浩焯·罗斯韦尔表示,尽管在破碎的地面上钻探很困难,但钻探表明,目标地球物理和断层结构可能存在重大变化,地质环境从未进行过测试,计划在2,200英尺处终止第一个孔时,结果出人意料地积极。我们对化验结果持谨慎乐观态度,我们预计未来几周内会有化验结果。

Angold has now completed logging of the core from AAU22-001 and AAU22-001A. The observations and data from the completed logging are consistent with the Company's exploration model within the Red Ridge Zone of the project, confirming a discovery of Carlin-style alteration below Ordovician Valmy Formation (see Figure 2), part of the Roberts Mountains Thrust plate, which appears to be continuous along a 6 km (~3.7 mi) strike length from Red Ridge Zone to the Northern Extension Zone. This supports the Company's interpretation of geophysical results from the Company's 2021 pre-drilling program demonstrating a large MT and IP anomaly at target depths. See the Company's previous news releases on April 19, 2022 and February 22, 2022.

AnGold现在已经完成了AAU22-001和AAU22-001a岩心的测井。完成测井的观测和数据与公司在该项目红脊地带的勘探模式一致,证实在罗伯茨山脉逆冲板块的一部分奥陶系瓦尔米组(见图2)下方发现了卡林式蚀变。从红脊带到北部延伸带的6公里(~3.7英里)走向似乎是连续的。这支持了公司对公司2021年钻探前计划的地球物理结果的解释,该计划显示了目标深度的大型大地电磁异常和激电异常。见该公司之前于2022年4月19日和2022年2月22日发布的新闻稿。

Drillhole AAU22-001 was stopped in late May at 273 metres (894.5') due to hole caving at ~183 metres (~600'), which Angold's drill contractor believes was the result of challenges associated with voids within the bedrock, sanded and broken ground in the upper plate zone. Drilling restarted on same pad with drillhole AAU22-001A, successfully installed PQ-sized drill rods to a depth of 251 metres (824') to effectively case off through the challenging interval, and continued to core drill with HQ rods to 514 metres (1,687') and NQ to the termination of the hole at 710 metres (2,329'). AAU22-01A was terminated below target depth within highly altered and fractured dolomitic siltstone, with decalcification, dolomitization, fine pyrite and carbon representing Carlin-style epithermal alteration (see Image 2).

Aau22-001号钻孔在5月下旬因~183米(~894.5‘)处的钻孔坍塌而停止,AnGold的钻探承包商认为这是与基岩内的空洞、上板块区域的砂砾和破碎地面相关的挑战的结果。随着AAU22-001a钻孔在相同的垫板上重新开始钻井,成功地将PQ尺寸的钻杆安装到251米(824‘)的深度以有效地通过具有挑战性的区间,并继续使用HQ钻杆和NQ钻杆取心钻头至514米(1,687’)和NQ至710米(2,329‘)的井底。AAU22-01a终止于目标深度以下的高度蚀变和破碎的白云质粉砂岩中,有脱钙、白云石化、细粒黄铁矿和碳代表卡林式浅成热液蚀变(见图2)。

Core Logging Summary
Drilling to date within and at depth below the Red Ridge zone encountered many epithermal quartz vein-veinlet zones displaying polyphase banding, some quartz after calcite pseudomorphs, and, in some cases, silver sulfide-selenide mineral (acanthite-aguilarite-naumannite) grains in specific bands. These textures and minerals together demonstrate the fertility of the system at this level and provide encouragement for significant precious metals potential at depth, where a boiling horizon in an idealized low-sulfidation epithermal system could occur.

岩心测井摘要
到目前为止,在红脊带内和之下的钻探遇到了许多浅成热液石英脉细脉带,显示出多相条带状,一些石英在方解石假象之后,在某些情况下,特定条带中的银硫化物-硒矿物(针铁矿-针铁矿-纽曼矿)颗粒。这些结构和矿物共同证明了该系统在这一水平上的肥力,并鼓励在深部具有显著的贵金属潜力,在那里可能会出现理想的低硫化浅成热液系统中的沸腾地层层。

Logging shows several areas with good potential for Au-Ag mineralization between 266 metres and 443 metres (874' and 1,452'), which is the main targeted area within this hole (Image 1). Abundant disseminated sulfides correlate well with the strong chargeability anomaly being tested, along with quartz veining in an interpreted steeply dipping structure from the MT section. Localized strong sooty sulfide-silica appears especially prospective. Of surprise and note is the apparent Carlin-style alteration starting at 428 metres (1,403'), which also correlates with the projected triple intersection of mineralized faults mapped at surface.

记录显示,在266米至443米(874‘至1,452’)之间有几个具有良好金银矿化潜力的区域,这是该孔内的主要目标区(图1)。丰富的浸染性硫化物与测试的强充电性异常以及来自MT剖面的解释的急倾斜构造中的石英脉很好地关联。局部化的强煤烟硫化物-二氧化硅显得特别有前景。令人惊讶和值得注意的是,从428米(1,403‘)开始的明显的卡林式蚀变,也与在地表绘制的矿化断层的预测三重交叉相关联。

Rock chip samples at surface in the Red Ridge zone, comprised of breccias and banded veinlets, have demonstrated silver grades to 600 g/t and gold grades to 4 g/t. It is encouraging to see silver sulfides at depth in veins within the same zone.

红岭带地表岩屑样品由角砾岩和条状细脉组成,银品位达600克/吨,金品位达4克/吨。在同一带内的矿脉中发现深部的银硫化物是令人鼓舞的。

Stratigraphy, Alteration and Oxidation
The high-angle faults and fractures seen in AAU22-001/AAU22-001A are associated with both intense oxidation, silicification and hydrothermal argillic alteration, evidencing the importance of these high-angle features in supporting and focusing vertical fluid flow along the margin of the Cateano Caldera. Importantly, as seen in AAU22-001A, the Carlin-style alteration features are contained within the Upper Plate of and may also be below the Roberts Mountains Thrust, supporting Angold's geologic model of an extensive Eocene-Oligocene hydrothermal system, consistent with the timing of Nevada's Carlin-type mineralizing events (approximately 40 - 35 Mya) and younger alteration-mineralization hosted in Oligocene Caetano Tuff (32-30 Ma).

地层、蚀变和氧化作用
在AAU22-001/AAU22-001a中发现的高角度断层和裂缝与强烈的氧化、硅化和热液泥化蚀变有关,证明了这些高角度特征在支持和集中沿卡特诺火山口边缘的垂直流体流动方面的重要性。重要的是,正如在AAU22-001A中所看到的,卡林式蚀变特征包含在罗伯茨山脉逆冲断层的上板块内,也可能在罗伯茨山脉逆冲带之下,支持AnGold的广泛的始新世-渐新世热液系统的地质模型,与内华达州卡林型矿化事件(约40-35Mya)和赋存于渐新世Caetano凝灰岩(32-30 Ma)的年轻蚀变矿化的时间一致。

The alteration products of the fracture-controlled fluid flow - projected to be travelling upwards and into the Antler Overlap Sequence, below the Golconda Thrust (the upper mineralized zone at the project) - are associated with the highly anomalous, sooty sulfides and green illite clay. Importantly, these sulfide concentrations along the fractures generally increase with depth within the Carlin-style alteration in dolomitic rocks encountered at the bottom of AAU22-01A. It is not clear at this time if the altered carbonate rocks encountered at the bottom of AAU22-01A are within the Roberts Mountains Thrust or below it. The shearing and alteration encountered is not likely to allow age dating of these carbonate rocks, which would be required to unequivocally say whether these rocks are Lower Plate carbonates or carbonate rocks within the Upper Plate of the Roberts Mountains Thrust (Valmy or Cormus).

断裂控制的流体流动的蚀变产物--预计向上移动并进入鹿角叠覆层序,位于戈尔孔达逆冲断层(该项目的上部矿化带)下方--与高度异常的烟尘状硫化物和绿色伊利石粘土有关。重要的是,这些沿着裂缝的硫化物浓度通常随着AAU22-01a底部遇到的白云岩中卡林式蚀变内的深度而增加。目前还不清楚在AAU22-01a底部遇到的蚀变碳酸盐岩是在罗伯茨山脉逆冲推覆还是在其下方。所遇到的剪切和蚀变不太可能对这些碳酸盐岩进行年龄测定,这将需要明确地说出这些岩石是下盘碳酸盐还是罗伯茨山脉逆冲上板块(Valmy或Cormus)内的碳酸盐岩。

Geology and Structure
The results of Angold's drill program confirm that gold-silver mineralization is believed to be controlled by a series of north-south, north-northeast and east-west structures that host silicification and epithermal quartz-pyrite-gold-silver mineralization within Pennsylvanian to Permian siltstones and argillites of the Cedars Sequence (Havallah) and Oligocene felsic volcanic rocks (Caetano Tuff). Mineralization is completely oxidized from surface up to 175 metres depth and continues as sulphides to depths beyond 250 metres. Mineralization is also disseminated between veins, silicified structures and brecciated zones, and can occur as silicified breccia zones at the contact between volcanic and underlying sedimentary rocks. Opaline silica, bladed quartz-chalcedony after calcite, polyphase banded quartz veins and natroalunite veins are exposed at surface, supporting the deduction that the epithermal system at Iron Butte is largely intact. Surface rock chip and soil sampling assay results also support this deduction, with highly elevated mercury, selenium and arsenic present. Quartz textures, alteration and mineralogy described support a low-sulfidation epithermal model, which will be used to guide-inform future exploration efforts at Iron Butte.

地质和构造
AnGold的钻探计划结果证实,金银矿化被认为受控于一系列北-南、北-东北和东西向构造,这些构造赋存于宾夕法尼亚至二叠纪锡达斯序列(Havallah)和渐新世长英质火山岩(Caetano Tuff)的粉砂岩和泥质岩中的硅化和低温石英-黄铁矿-金银矿化。矿化从地表到175米深度被完全氧化,并以硫化物的形式持续到250米以上的深度。矿化还分布在矿脉、硅化构造和角砾岩带之间,并可作为硅化角砾岩带出现在火山岩和下伏沉积岩的接触处。地表露出乳白色二氧化硅、方解石后的片状石英玉髓、多相条带状石英脉和钠长石脉,支持铁角岩的低温热液系统基本完好的推断。地表岩屑和土壤采样分析结果也支持这一推论,汞、硒和砷的含量都很高。所描述的石英结构、蚀变和矿物学支持低硫化浅成热液模型,该模型将用于指导未来在Iron Butt的勘探工作。
