Vancouver, British Columbia--(Newsfile Corp. - July 20, 2022) - Altamira Gold Corp. (TSXV: ALTA) (FSE: T6UP) (OTC PINK: EQTRF), ("Altamira" or the "Company") is pleased to provide an update on its ongoing exploration programme for copper and gold at the Santa Helena project in Mato Grosso State, Northern Brazil.

温哥华,不列颠哥伦比亚省-(Newsfile Corp.-2022年7月20日)-阿尔塔米拉黄金公司(多伦多证券交易所股票代码:ALTA)(证券交易所代码:T6UP)(场外粉色股票代码:EQTRF), ("阿尔塔米拉“或”公司“)很高兴介绍其在巴西北部马托格罗索州圣赫勒拿项目正在进行的铜和金矿勘探计划的最新情况。

Highlights:

重点:

  • Additional soil sampling in the Santa Helena project has defined a significant second copper-in-soil anomaly and also confirmed consistent copper values in the original soil anomaly. Both are being prepared for drill testing
  • 圣赫勒拿项目的额外土壤采样确定了第二个显着的土壤中铜异常,并确认了原始土壤异常中一致的铜值。两家公司都在为钻探测试做准备
  • These anomalies measure 500 by 500m and 800 by 600m respectively and have consistent soil values above 46ppm with a peak of 448ppm
  • 这些异常的大小分别为500×500米和800×600米,并具有46ppm以上的稳定土壤值,峰值为448ppm
  • Both copper-in-soil anomalies have associated NE/SW trending gold vein occurrences on their periphery. Scout drilling of these gold vein systems has identified porphyry-style alteration and veining in wall-rocks to the mineralized veins. Both molybdenite and chalcopyrite have been identified in these veins
  • 两个土壤铜异常在其外围均伴生有NE/SW向的金脉产出。通过对这些金脉系统的勘察钻探,发现了围岩中的斑岩式蚀变和矿化矿脉。在这些矿脉中发现了辉钼矿和黄铜矿。
  • Confirmation of the prospectivity of the Santa Helena project for the preservation of proterozoic porphyry-style mineralization provides Altamira Gold with an exciting new target in addition to the high-grade gold and base metal veins already identified
  • 圣赫勒拿保存元古代斑岩型矿化项目前景的确认为阿尔塔米拉金矿提供了一个令人兴奋的新目标,除了已查明的高品位金和贱金属矿脉

CEO Mike Bennett commented; "The definition of a second significant copper-in-soil anomaly adjacent to our existing gold targets, and in association with porphyry-style alteration in drill core, is an exciting development and suggests that there is significant copper potential within our licenses at Santa Helena. The preservation of the upper and generally higher-grade parts of such alteration systems is rare in rocks of this age. However, the thick volcanics and sedimentary cover sequences that we believe formerly covered the area, appear to have contributed to the preservation of the prospective structural level where porphyry mineralization can be found. We look forward to drill testing these targets in a cost effective and speedy manner whilst we wait for drill results on a number of the peripheral gold targets".

首席执行官Mike Bennett评论说:“在我们现有的金矿目标附近发现第二个重要的土壤中铜异常,并与钻芯中的斑岩式蚀变相关联,这是一个令人兴奋的发展,表明我们在Santa Helena的许可证中有巨大的铜潜力。在这个时代的岩石中,保存这种蚀变系统的上部和一般较高等级的部分是很少见的。然而,我们认为以前覆盖该地区的厚厚的火山岩和沉积盖层似乎有助于保存斑岩成矿的预期构造水平。我们期待着以经济高效和快速的方式对这些目标进行钻探测试,同时等待一些外围黄金目标的钻探结果“。

SANTA HELENA PROJECT

圣赫勒拿项目

The Santa Helena project is located immediately adjacent to the paved BR-163 federal highway in the state of Mato Grosso and 60km SW of the Jaca porphyry copper deposit which was recently discovered by Anglo American Corporation (Figure 1).

圣赫勒拿项目紧邻马托格罗索州已铺面的BR-163联邦骇维金属加工,以及英美资源集团最近发现的雅莎斑岩铜矿西南60公里处(图1)。

There is no history of copper production in the Santa Helena area and previous artisanal mining activity has focused on high-grade gold, hosted in vein structures.

圣赫勒拿地区没有铜生产的历史,以前的手工采矿活动主要集中在矿脉结构中的高品位黄金上。

The regional geology (Figure 2) indicates a genetic link between the Teles Pires intrusives and the Colider Formation volcanics, which is supported by regional scale geochemistry and geochronology with both units ranging in age from 1806-1757Ma. The Colider Fm consists of lavas and pyroclastic flows with inferred volcanic dome structures. The Teles Pires intrusives consist of alkali-feldspar granites and syenogranites and are interpreted to be the main host to porphyry-style intrusions in the Santa Helena area. Younger (ca.1400Ma) sedimentary cover of conglomerates and arenites formerly overlay this basement. This cover, which is now reflected as remnant outliers, may have aided the preservation of porphyry alteration zones within the basement.

区域地质(图2)表明Teles Pires侵入岩和Colider组火山岩之间存在成因联系,这得到了区域尺度地球化学和地质年代学的支持,两个单位的年龄都在1806-1757 Ma之间。Colider FM由熔岩和火山碎屑流组成,推测为火山穹隆结构。Teles Pires侵入岩由碱性长石花岗岩和正长花岗岩组成,被解释为圣赫勒拿地区斑岩式侵入岩的主要宿主。较年轻的(约1400 Ma)砾岩和砂岩的沉积盖层以前覆盖在这个基底上。这一盖层现在被反映为残留的离群值,可能有助于保存基底内的斑岩蚀变带。

In a similar manner to the Jaca porphyry district (60km NE), anomalous copper occurrences at Santa Helena have associated peripheral gold occurrences. Mapping, soil and rock chip sampling by Altamira has previously identified both extensions to the known vein gold targets plus significant copper, molybdenum and gold anomalies in soils related to areas of porphyry-style alteration in a zone which extends 7km E-W by 4 km N-S, indicating the presence of a very large hydrothermal system. Pervasive "red rock" alteration of the host intrusive rocks is found in many of the holes drilled to date.

与雅卡斑岩区(东北60公里)类似,圣赫勒拿的异常铜矿与周边金矿有关。阿尔塔米拉公司此前在地图绘制、土壤和岩石芯片采样中发现了已知脉状金矿目标的两个延伸区域,以及与斑岩式蚀变区域有关的土壤中的显著铜、钼和金异常,该区域东西向延伸7公里,南北向延伸4公里,表明存在一个非常大的热液系统。到目前为止,在许多已钻探的孔中都发现了寄主侵入岩普遍存在的“红岩”蚀变。

Recent soil sampling at Santa Helena has identified a second significant copper-in-soil anomaly 3km SW of the initial copper anomaly (Figure 3). This second anomaly measures 500 x 500m and is characterised by copper values in soils above 46ppm with maximum values of 154 ppm . The original copper-in-soil anomaly measures 800 x 600m. Neither anomaly has been tested to date but recent drilling on some of the peripheral gold occurrences has identified porphyry-style alteration and veining.

圣赫勒拿最近的土壤采样发现了第二个显着的土壤中铜异常,位于初始铜异常西南3公里处(图3)。第二个异常为500×500米,特征是土壤中的铜值高于46ppm,最大值为154ppm。原始土壤铜异常为800×600米。到目前为止,这两个异常都没有得到测试,但最近在一些外围金矿床上的钻探发现了斑岩式的蚀变和脉状。

At least three different generations of veining have been observed in drill core (Figure 5), indicating an alteration system that was reactivated in different temperature regimes, currently interpreted as reflecting the distal part of a cooling hydrothermal system associated with a local (porphyry) intrusion.

在钻芯中观察到了至少三代不同的脉络(图5),表明在不同的温度条件下重新激活了蚀变系统,目前的解释是反映了与局部(斑岩)侵入有关的冷却热液系统的远端部分。

Altamira plans to conduct drone magnetometer surveys plus IP profiles over the defined copper-in-soil anomalies to accelerate the selection of optimal drill targets in Q3 2022.

阿尔塔米拉计划在2022年第三季度对已定义的土壤中铜异常进行无人机磁力仪测量和激电剖面,以加快选择最佳钻探目标。

Results are currently pending on the 23 diamond-drill holes which have recently tested a number of the peripheral gold targets peripheral to the copper-in-soil anomalies. Results will be released once received from the laboratory.

目前正在等待23个钻石钻孔的结果,这些钻孔最近测试了土壤中铜异常外围的一些外围金靶。一旦从实验室收到结果,就会公布。
