US Copper Corp. Announces Drill Program at Moonlight-Superior Copper Project
Toronto, Ontario--(Newsfile Corp. - March 1, 2023) - US Copper Corp. (TSXV: USCU) (OTCQB: USCUF) (FSE: C730) ("US Copper" or the "Company") is pleased to announce it has signed a contract for a drill program at the Engels deposit, part of the Company's wholly-owned Moonlight-Superior Copper Project, located in Plumas County, California. The drill program will include 15 reverse circulation drill holes into the oxide cap that sits on top of the Engels' sulfide deposit. The drill program is scheduled to commence in the second quarter 2023, when access permits.
安大略省多倫多-(Newsfile Corp.-2023年3月1日)-美國銅業公司(TSXV:USCU)(OTCQB:USCUF)(FSE:C730) ("美國銅業“或”公司“)很高興地宣佈,它已經簽署了恩格斯礦藏鑽探項目的合同,該礦藏是公司全資擁有的Moonlight-Superior銅礦項目的一部分,位於加利福尼亞州普盧馬斯縣。鑽探項目將包括15個反向循環鑽孔,鑽入位於恩格斯硫化物礦藏頂部的氧化物蓋子。鑽探項目計劃於2023年第二季度開始,屆時訪問許可。
Objectives of the drill program include:
演習計劃的目標包括:
- Upgrading and potentially expanding the current oxide resource estimate;
- Providing samples for preliminary metallurgical evaluation; and
- Providing initial data for inclusion in a preliminary economic assessment ("PEA") on the Engels oxide deposit.
- 升級並有可能擴大目前的氧化物資源估計;
- 提供用於初步冶金評價的樣品;以及
- 提供初步數據以納入初步經濟評估(“豌豆“)恩格斯氧化物礦牀。
The oxide cap at Engels is developed to depths greater than 230 feet ("ft") over an area of at least 1,000 ft by 500 ft. Sample intercepts from prior drill programs reveal a high-grade copper oxide cap as the table below illustrates. These results were included in the 2013 resource estimate of 2.5 million tons ("MT") at 1.05% as contained in the Company's NI 43-101Technical Report and Resource Estimate for the Superior Project, Plumas County, California, with a refiled date of November 7, 2014, which can be viewed on the US Copper's website and on .
恩格斯的氧化帽深度超過230英尺(“金融時報“)覆蓋了至少1,000英尺乘500英尺的區域。以前鑽探項目截獲的樣本顯示出一個高品位的氧化銅蓋子,如下表所示。這些結果包括在2013年250萬噸的資源估計中(”Mt.“)1.05%,載於公司關於加州Plumas縣Superior項目的NI 43-101技術報告和資源評估,重新提交日期為2014年11月7日,可在美國銅業的網站和其他網站上查看。

Management Commentary
管理評論
"In 2022, the Company elected to conserve capital and review our large historic database for additional opportunities," commented Stephen Dunn, US Copper's President and CEO. "Prior operators had identified oxide caps at both Moonlight and Engels. That led us to reevaluate the potential to develop a starter oxide open pit mine at Engels through a first phase drill program aimed at establishing greater oxide mineralization at Engels than what was included in the 2014 resource estimate."
美國銅業首席執行官總裁兼首席執行官斯蒂芬·鄧恩評論道:2022年,公司選擇節約資本,並審查我們龐大的歷史數據庫,以尋找更多機會。“之前的運營商在Moonlight和Engels都發現了氧化物上限。這導致我們重新評估了通過第一階段鑽探計劃在Engels開發起始氧化物露天礦的潛力,該計劃旨在建立比2014年資源估計中包括的更大的恩格斯氧化物礦化。”
"This oxide mineralization is not closed off in any direction and has the potential to be a stand-alone, open pit copper mine. Once we have further delineated and defined the oxide resource at Engels, a preliminary economic assessment can be undertaken to explore a starter pit production scenario while we further develop mining scenarios for the larger sulfide deposits at Moonlight. In conjunction with the Moonlight deposit and the Superior deposit, which was enhanced by last year's drill program, the combined 3-pit resource has the potential to be a long-lived profitable mining operation."
“這種氧化物礦化沒有在任何方向上被封閉,有可能成為一個獨立的露天銅礦。一旦我們進一步圈定和定義了恩格斯的氧化物資源,就可以進行初步的經濟評估,以探索初始礦坑生產方案,同時我們進一步開發Moonlight較大硫化物礦牀的開採方案。再加上Moonlight礦藏和去年鑽探計劃增強的Superior礦藏,合併後的三礦資源有可能成為一項長期盈利的採礦業務。”
Background
背景
The Engels deposit is one of 3 significant copper deposits on US Copper's Moonlight-Superior property. It is located 6,000 ft east of our 300 MT 0.30% copper Moonlight deposit and 11,000 ft north of the 60 MT 0.43% copper Superior deposit (see "Technical Report and Preliminary Economic Assessment for the Moonlight Deposit, Moonlight-Superior Copper Project, California, USA" dated April 12, 2018). Initial efforts to mine-process the oxide (carbonate) ore in the early 1900's failed due to technological shortcomings. In 1914-15 sulfide ore was discovered at Engels during development of the 5th level, and shortly thereafter Engels and the nearby Superior properties were consolidated under the Engels Mining Company and production and processing of the sulfide ore began. Consolidated production from Engels-Superior in the 1915-1930 period yielded approximately 4.2 MT of ore at a grade of 2.2% copper. The majority of the production came from Engels. Mine workings at Engels are extensive and include many tens of thousands of feet of drifts, crosscuts, and stopes on ten levels accessed by adits and six levels accessed from a winze sunk from the No. 10 level.
恩格斯銅礦是美國銅業Moonlight-Superior地產上的3個重要銅礦之一。它位於我們300 MT 0.30%的Moonlight銅礦以東6,000英尺,60 MT 0.43%的Superior銅礦以北11,000英尺(見2018年4月12日美國加利福尼亞州Moonlight-Superior銅礦項目的技術報告和初步經濟評估)。20世紀初,由於技術缺陷,最初開採和加工氧化(碳酸鹽)礦石的努力失敗了。1914-1915年,在恩格斯的五礦開發過程中發現了硫化礦。這是此後不久,恩格斯礦業公司和附近的Superior礦產被併入恩格斯礦業公司,並開始生產和加工硫化礦石。恩格斯-蘇必利爾礦在1915-1930年間的綜合生產產生了大約4.2公噸的礦石,銅品位為2.2%。大部分作品出自恩格斯之手。恩格斯的礦山採掘範圍很廣,包括十個水平上的數萬英尺的平巷、橫切和採場,以及從10號水平下沉的Winze進入的六個水平。
In the 1960s-70s Placer AMEX did extensive work in the district which resulted in the discovery of the Moonlight deposit, partial delineation of the Superior deposit and an evaluation of the Engels deposit that included an internal company open pit estimate of 19 million tons of sulfide material with a grade of 0.63% Copper.
在20世紀60年代至70年代,Placer AMEX在該地區進行了廣泛的工作,結果發現了Moonlight礦牀,部分圈定了Superior礦牀,並對Engels礦牀進行了評估,其中包括公司內部露天礦場估計的1900萬噸含銅0.63%的硫化物材料。
US Copper had a PEA prepared on its Moonlight deposit in 2018 that showed positive economics at $3.15 per pound copper. It was determined that providing higher grade ore from our Superior and/or Engels deposits into the Moonlight mine plan would substantially enhance the Project's economics by potentially increasing cash flows in the initial years of production. The recently completed drill program at Superior was designed specifically for that purpose, and this Engels Phase I Program will outline the potential for a second starter pit for the Moonlight plant. Ultimately, the updated Engels and Superior resources will be incorporated into a revised Moonlight PEA.
2018年,美國銅業在其月光礦藏上準備了一份PEA,顯示出積極的經濟效益,每磅銅3.15美元。已確定,從我們的Superior和/或Engels礦藏中向Moonlight礦山計劃提供品位較高的礦石,可能會在投產的最初幾年增加現金流,從而大幅提高項目的經濟效益。最近在Superior完成的鑽探計劃就是專門為此目的而設計的,恩格斯第一階段計劃將概述Moonlight工廠第二個啟動坑的潛力。最終,更新的恩格斯和高級資源將被合併到修訂的月光PEA中。
