Altamira Gold Identifies Second Significant Copper Anomaly at the Santa Helena Project
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.
温哥華,不列顛哥倫比亞省-(Newsfile Corp.-2022年7月20日)-阿爾塔米拉黃金公司(多倫多證券交易所股票代碼:ALTA)(證券交易所代碼:T6UP)(場外粉色股票代碼:EQTRF), ("阿爾塔米拉“或”公司“)很高興介紹其在巴西北部馬託格羅索州聖赫勒拿項目正在進行的銅和金礦勘探計劃的最新情況。
Highlights:
重點:
- 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
- 聖赫勒拿項目的額外土壤採樣確定了第二個顯着的土壤中銅異常,並確認了原始土壤異常中一致的銅值。兩家公司都在為鑽探測試做準備
- These anomalies measure 500 by 500m and 800 by 600m respectively and have consistent soil values above 46ppm with a peak of 448ppm
- 這些異常的大小分別為500×500米和800×600米,並具有46ppm以上的穩定土壤值,峯值為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
- 兩個土壤銅異常在其外圍均伴生有NE/SW向的金脈產出。通過對這些金脈系統的勘察鑽探,發現了圍巖中的斑巖式蝕變和礦化礦脈。在這些礦脈中發現了輝鉬礦和黃銅礦。
- 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
- 聖赫勒拿保存元古代斑巖型礦化項目前景的確認為阿爾塔米拉金礦提供了一個令人興奮的新目標,除了已查明的高品位金和賤金屬礦脈
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".
首席執行官Mike Bennett評論説:“在我們現有的金礦目標附近發現第二個重要的土壤中銅異常,並與鑽芯中的斑巖式蝕變相關聯,這是一個令人興奮的發展,表明我們在Santa Helena的許可證中有巨大的銅潛力。在這個時代的巖石中,保存這種蝕變系統的上部和一般較高等級的部分是很少見的。然而,我們認為以前覆蓋該地區的厚厚的火山巖和沉積蓋層似乎有助於保存斑巖成礦的預期構造水平。我們期待着以經濟高效和快速的方式對這些目標進行鑽探測試,同時等待一些外圍黃金目標的鑽探結果“。
SANTA HELENA PROJECT
聖赫勒拿項目
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).
聖赫勒拿項目緊鄰馬託格羅索州已鋪面的BR-163聯邦駭維金屬加工,以及英美資源集團最近發現的雅莎斑巖銅礦西南60公里處(圖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.
聖赫勒拿地區沒有銅生產的歷史,以前的手工採礦活動主要集中在礦脈結構中的高品位黃金上。
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.
區域地質(圖2)表明Teles Pires侵入巖和Colider組火山巖之間存在成因聯繫,這得到了區域尺度地球化學和地質年代學的支持,兩個單位的年齡都在1806-1757 Ma之間。Colider FM由熔巖和火山碎屑流組成,推測為火山穹隆結構。Teles Pires侵入巖由鹼性長石花崗巖和正長花崗巖組成,被解釋為聖赫勒拿地區斑巖式侵入巖的主要宿主。較年輕的(約1400 Ma)礫巖和砂巖的沉積蓋層以前覆蓋在這個基底上。這一蓋層現在被反映為殘留的離羣值,可能有助於保存基底內的斑巖蝕變帶。
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.
與雅卡斑巖區(東北60公里)類似,聖赫勒拿的異常銅礦與周邊金礦有關。阿爾塔米拉公司此前在地圖繪製、土壤和巖石芯片採樣中發現了已知脈狀金礦目標的兩個延伸區域,以及與斑巖式蝕變區域有關的土壤中的顯著銅、鉬和金異常,該區域東西向延伸7公里,南北向延伸4公里,表明存在一個非常大的熱液系統。到目前為止,在許多已鑽探的孔中都發現了寄主侵入巖普遍存在的“紅巖”蝕變。

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.
聖赫勒拿最近的土壤採樣發現了第二個顯着的土壤中銅異常,位於初始銅異常西南3公里處(圖3)。第二個異常為500×500米,特徵是土壤中的銅值高於46ppm,最大值為154ppm。原始土壤銅異常為800×600米。到目前為止,這兩個異常都沒有得到測試,但最近在一些外圍金礦牀上的鑽探發現了斑巖式的蝕變和脈狀。

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.
在鑽芯中觀察到了至少三代不同的脈絡(圖5),表明在不同的温度條件下重新激活了蝕變系統,目前的解釋是反映了與局部(斑巖)侵入有關的冷卻熱液系統的遠端部分。

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.
阿爾塔米拉計劃在2022年第三季度對已定義的土壤中銅異常進行無人機磁力儀測量和激電剖面,以加快選擇最佳鑽探目標。
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個鑽石鑽孔的結果,這些鑽孔最近測試了土壤中銅異常外圍的一些外圍金靶。一旦從實驗室收到結果,就會公佈。
