Vancouver, British Columbia--(Newsfile Corp. - February 2, 2022) - Altamira Gold Corp. (TSXV: ALTA) (FSE: T6UP) (OTC PINK: EQTRF) ("Altamira" or the "Company") is pleased to announce that its first three diamond drillholes have intersected porphyry style alteration and mineralization at the Santa Helena porphyry copper-gold project in Mato Grosso State, Northern Brazil. Core samples are being prepared and will be dispatched during February to the SGS Laboratory in Belo Horizonte for assay.

温哥华,不列颠哥伦比亚省-(Newsfile Corp.-2022年2月2日)阿尔塔米拉黄金公司(多伦多证券交易所代码:ALTA)(证券交易所代码:T6UP)(场外交易代码:EQTRF) ("阿尔塔米拉“或”公司“)很高兴地宣布,在巴西北部马托格罗索州的Santa Helena斑岩铜金矿项目中,其首批三个钻石钻孔已经与斑岩风格的蚀变和矿化相交。岩心样品正在准备中,将于2月份被送往贝洛奥里藏特的SGS实验室进行分析。

Highlights:

重点:

  • The initial three drillholes at the Gabriel target at Santa Helena have confirmed the occurrence of alteration and mineralization typical of porphyry copper systems at depth
  • 圣海伦娜Gabriel目标的最初三个钻孔证实了深部斑岩铜矿系统中典型的蚀变和矿化的存在。
  • Geological consultants, Dr. Alan Wilson and Darren Jones MSc, both with extensive Latin American porphyry exploration experience, have confirmed their view that the intersections in the initial three drill holes show alteration typical of porphyry systems
  • 地质顾问艾伦·威尔逊(Alan Wilson)博士和达伦·琼斯硕士(Darren Jones MSc)博士都有丰富的拉丁美洲斑岩勘探经验,他们已经证实了他们的观点,即最初三个钻孔的交叉点显示出典型的斑岩系统的蚀变。
  • Confirmation of the prospectivity of the belt for the preservation of Proterozoic porphyry copper deposits provides Altamira Gold with an exciting new target style in addition to the high-grade gold and base metal veins already identified
  • 元古界斑岩铜矿带保存前景的确认为阿尔塔米拉金矿提供了一个令人振奋的新的靶区样式,除了已查明的高品位金和贱金属矿脉外,还为阿尔塔米拉金矿提供了一个令人兴奋的新靶区样式

CEO Mike Bennett commented; "The identification of compelling evidence of porphyry-style alteration at depth at Santa Helena is extremely encouraging so early in the drill program, and with a 28 square kilometer area of known surface copper and gold mineralization, we now need to use geophysical exploration techniques over this area to help identify the best drill targets for the second phase of drilling. This new porphyry discovery by Altamira is only 60 kilometers to the south-west of the Jaca Porphyry Copper discovery by Anglo American in 2017 and we are extremely excited for both the copper and gold potential within our extensive Santa Helena Project."

首席执行官Mike Bennett评论说:“在钻探计划的早期,在圣赫勒拿发现了令人信服的斑岩式深部蚀变证据,这是非常令人鼓舞的,鉴于已知的地表铜矿和金矿化面积为28平方公里,我们现在需要在这一地区使用地球物理勘探技术来帮助确定第二阶段钻探的最佳钻探目标。阿尔塔米拉公司新发现的斑岩距离英美资源集团2017年发现的雅莎斑岩铜矿只有60公里,我们感到非常兴奋。

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号联邦骇维金属加工,以及英美资源集团最近发现的雅卡斑岩铜矿西南60公里处(图1)。

Structural interpretation on a regional scale has shown the proximity of both the Jaca porphyry copper deposit and the Santa Helena porphyry system to the structural break marked as Santa Helena Shear zone shown in Figure 2.

区域尺度的构造解释表明,雅卡斑岩铜矿和圣赫勒拿斑岩系统都接近图2所示的标记为圣赫勒拿剪切带的构造断裂带。

Previous artisanal mining activity has focused on high-grade gold hosted in vein structures. However, mapping, soil and rock chip sampling by Altamira has 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 (Figure 3).

以前的手工开采活动主要集中在矿脉结构中的高品位黄金上。然而,阿尔塔米拉公司的测绘、土壤和岩屑取样发现,已知脉状金矿目标的范围既有扩大,又有与斑岩式蚀变区域有关的土壤中出现显著的铜、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(图3)。

The area consists of undulating farmland with generally poor outcrop and saprolite weathering up to 57m deep as shown in drillhole DDSTH-02.

该地区由起伏的农田组成,露头一般较差,腐泥岩风化深度达57米,如DDSTH-02钻孔所示。

图3:圣赫勒拿项目内的主要目标。注意高品位金矿点上分布广泛的历史矿坑。已经在加布里埃尔矿坑进行了钻探,主要是土壤中的铜异常。

Three angled diamond drill holes, up to 340m deep have thus far been completed around the Gabriel pit. These holes targeted a strong IP chargeability anomaly and stockwork mineralization mapped and sampled on surface in the southern wall of the Gabriel pit (Figure 4).

到目前为止,加布里埃尔矿坑周围已经完成了三个深达340米的斜角钻石钻孔。这些钻孔的目标是在Gabriel矿坑南壁的地表绘制和取样的强烈激电可充电性异常和网状矿化(图4)。

图4:圣赫勒拿Gabriel矿坑区域的IP可充电性地图-注意到存在一个强烈的可充电性异常,该异常延伸到东南方向,远离Gabriel矿坑内表面的网状石英脉。

All of the initial three drillholes intersected strong porphyry-style alteration associated with variable quantities of disseminated sulphides (Figures 5,6,7,8 and 9). Analytical results are pending.

最初的三个钻孔都与与不同数量的浸染硫化物有关的强烈斑岩式蚀变相交(图5、6、7、8和9)。分析结果待定。

Consulting geologist and porphyry expert, Dr. Alan Wilson was engaged to review all of the core photographs and exploration data. He commented; "A review of selected core photos from three holes recently completed at Santa Helena clearly shows vein types and alteration assemblages which are typical of those found in porphyry copper-gold systems globally and share many features of silica-saturated alkalic porphyry systems, namely:

咨询地质学家和斑岩专家艾伦·威尔逊(Alan Wilson)博士被聘请来审查所有的核心照片和勘探数据。他评论说:“对最近在圣赫勒拿完成的三个孔的精选岩心照片的回顾清楚地显示了脉型和蚀变组合,这些脉型和蚀变组合是全球斑岩铜-金系统中发现的典型特征,并具有许多饱和硅质碱性斑岩系统的特征,即:

  • Sheeted to stockwork quartz ±carbonate veins with pyrite ±chalcopyrite mineral assemblages
  • Aplite dykes associated with thick quartz veins and coarse grained pyrite and molybdenite
  • Late-stage epidote-calcite veining with associated hematite (red rock) alteration
  • Spatial association of quartz veining with pink, K-feldspar-rich (alteration, magmatic or both), pink to red (hematite-altered "red rock") granitic intrusions"
  • 片状为网状石英±碳酸盐脉,含黄铁矿±黄铜矿矿物组合
  • 与厚石英脉和粗粒黄铁矿、辉钼矿共生的闪长岩脉
  • 晚期绿帘石-方解石脉与伴生赤铁矿(红岩)蚀变
  • 石英脉与粉红色、富钾长石(蚀变、岩浆或两者兼有)、粉红色至红色(赤铁矿蚀变的“红岩”)花岗岩侵入体的空间组合

Altamira is planning drone magnetometer surveys and IP surveys to optimise initial drill tests of the coherent copper-in-soil anomaly measuring 1000m by 1,200m to the north-east of the initial drilling area. Due to the very deep weathering profile, preservation of copper in soil at surface is a very positive indicator of mineralization at depth.

阿尔塔米拉公司正计划进行无人机磁力仪测量和激电测量,以优化初始钻探区域东北部1000米乘1200米的土壤中铜含量相关异常的初始钻探测试。由于风化剖面很深,表层土壤中铜的保存是深部矿化的一个非常积极的标志。

Altamira is now in the process of accelerating geophysical surveys in order to site drillholes over the copper anomaly outlined in soil sampling.

阿尔塔米拉目前正在加速进行地球物理勘测,以便在土壤采样中勾勒出的铜异常上定位钻孔。

APIACAS PROJECT

APIACAS项目

Diamond drilling and soil sampling are also in progress at the Mutum target within the Apiacas Project area. A total of nine holes have been completed to date with results pending on seven holes.

阿皮亚卡斯项目地区内的穆图姆目标也在进行钻石钻探和土壤采样。到目前为止,总共已经完成了9个洞,其中7个洞的结果尚待公布。
