VANCOUVER, BC / ACCESSWIRE / June 15, 2023 / Aztec Minerals Corp. (TSX-V:AZT)(OTCQB:AZZTF) announces it has received assay results from the final three drill holes of its 2023 core drilling program at the Tombstone project in the historic Tombstone silver mining district in southeastern Arizona. Aztec holds a 75% interest in the Tombstone Property Joint Venture, which includes most of the original patented mining claims in the district as well as some recently acquired properties. The three drill holes are part of a recently completed 7-hole program that was drilled in a fan-grid pattern over the length of the Contention zone target. Multiple underground mine workings were intersected in all the drill holes.
不列顛哥倫比亞省溫哥華/ACCESSWIRE /2023 年 6 月 15 日/阿茲臺克礦業公司 (TSX-V: AZT) (OTCQB: AZZTF) 宣佈已收到其2023年岩心鑽探項目最後三個鑽孔的化驗結果,該項目位於亞利桑那州東南部歷史悠久的Tombstone銀礦區的Tombstone項目。阿茲臺克人持有Tombstone Property合資企業75%的權益,其中包括該地區最初的大部分專利採礦權益以及最近收購的一些房產。這三個鑽孔是最近完成的 7 孔項目的一部分,該項目是在爭奪區目標的長度上以扇形網格模式鑽出的。在所有鑽孔中,多個地下礦井都相交。
High grade gold and silver was encountered in TC23-02 within a zone of oxidized, altered siltstones/hornfels, sandstones/quartzites, Qfp dikes and hydrothermal breccias at depths between 13.7 m and 135.0 m. Drill hole TC23-02 intersected, at 86.9 m to 132.1 m, a broad, oxidized zone of 45.3 m averaging 1.69 gpt Au and 29.07 gpt Ag (2.04 gpt AuEq), including 6.63 gpt Au & 72.81 gpt Ag (7.49 gpt AuEq) over a 10.1 m width. Gold equivalence (AuEq) for the drill hole intercepts were calculated using an 80:1 silver:gold ratio. Drill holeTC23-02 was collared 50 m west as a step to the 2021 drillholes on the "M section line" on the western portion of the main Contention pit.
在 TC23-02 中發現了高品位的金和銀,位於兩者之間的深度爲氧化、改變的粉砂岩/角巖、砂岩/石英岩、Qfp 堤壩和熱液角礫岩區域 13.7 米和 135.0 米。鑽孔 TC23-02 相交,位於 86.9 米至 132.1 米,a 寬闊的氧化區爲 45.3 m,平均值爲 1.69 gpt Au 和 29.07 gpt Ag (2.04 gpt aueQ),包括 6.63 gpt Au & 72.81 gpt Ag (7.49 gpt aueQ) 寬度超過 10.1 m。鑽孔截面的金當量 (auEQ) 是使用 80:1 的銀金比率計算得出的。Holetc23-02 鑽孔位於向西 50 米處,這是通往主爭鬥坑西部的 “M 區間線” 上的 2021 年鑽孔的一步。
Drill Hole TC23-02 was initially drilled to a depth of 27 m, before difficult drilling conditions resulted in a temporary abandonment of the drill hole in mid-March. The drill hole was then re-entered in late April and was successfully extended to a total depth of 135 m. This hole crossed several workings related to the historic third and fourth mine levels, including backfilled stopes.
TC23-02 鑽孔最初的鑽深度爲 27 米,之後困難的鑽孔條件導致鑽孔在 3 月中旬暫時被放棄。然後,該鑽孔在4月下旬重新進入併成功延伸至總深度135米。該孔穿過了與歷史上的第三和第四層礦山相關的多個工序,包括回填採口。
Hole TC23-06 was collared adjacent to the Grand Central shaft in the northern end of the Grand Central (South) pit. The vertical drill hole encountered from 29.6 m to 71.7 m an intersection of 42.1 m of 0.40 gpt Au and 30.79 gpt Ag (0.78 gpt AuEq) in an oxidized, high angle zone of altered siltstones/hornfels, sandstones/quartzites, mafic and Qfp dikes and hydrothermal breccias with multiple historic mine workings. It verifies the continuation and quality of the Contention zone mineralization between the Main (North) and Grand Central (South) pits.
TC23-06 洞位於大中央車道(南部)礦坑北端的大中央豎井附近。遇到的垂直鑽孔來自 29.6 米到十字路口 71.7 米 的 42.1 m of 0.40 gpt Au 和 30.79 gpt Ag (0.78 gpt aueQ) 位於由改變的粉砂岩/角巖、砂岩/石英岩、鎂鐵質和Qfp堤壩以及具有多個歷史礦山開採的熱液角礫岩組成的氧化高角度區域。它驗證了主礦坑(北部)和中央礦坑(南部)之間爭奪區礦化的延續性和質量。
Hole TC23-07 was collared in the northern portion of the Main pit adjacent to the east pit wall. The hole was drilled into the east pit wall and encountered from 6.1 m to 24.4 m an intersection of 18.3 m with 0.26 gpt Au and 7.43 gpt Ag (0.36 gpt AuEq) in oxidized, altered siltstones and sandstones and hydrothermal breccias with historic mine workings.
TC23-07 洞位於主礦坑的北部,毗鄰東坑牆。這個洞是在東坑的牆上鑽出來的 6.1 m 到 24.4 m,18.3 m 與 0.26 gpt Au 和 7.43 gpt Ag (0.36 gpt aueQ) 的交叉點)位於氧化的、變質的粉砂岩和砂岩以及具有歷史礦山開採過程的熱液角礫岩中。

Drill holes TC23-02 and TC23-07 were designed to expand the known mineralization in the central and northern portions of the main Contention pit to the west, east and to depth. TC23-06 verified the continuation and quality of the Contention mineralization between the Main and Grand Central (South) pits.
鑽孔 TC23-02 和 TC23-07 旨在將主競爭礦坑中部和北部的已知礦化向西、向東和深度擴展。TC23-06 驗證了主礦坑和大中部(南部)礦坑之間的 Contation 礦化的延續性和質量。
The core drilling program was planned to be able to pass through the intricate levels of old mine workings and multiple faults and to reach, at a minimum, the water table just below the sixth level and the principal district host limestones at depth. TC23-01, 05, 06 and 07 were able to reach their target depths. The drilling to date has expanded the extent of the entire Contention zone's mineralization to the west, east and to depth and demonstrates the potential for the volume of oxidized Au-Ag mineralization to grow as it remains open.
岩心鑽探計劃旨在能夠穿過錯綜複雜的舊礦井和多個斷層,並至少達到略低於六層的地下水位和主要區域的深度存在石灰岩。TC23-01、05、06 和 07 得以到達目標深度。迄今爲止的鑽探已將整個爭奪區的礦化範圍擴大到西部、東部和深度,並表明氧化金銀礦化量在保持開放狀態時有可能增加。
The core drilling program intersected extensive gold and silver mineralization, see table below, extending the mineralized zone at depth west, east and below the Contention zone's open pits. The drill holes also intersected historic mine stope workings, likely dating back to the late 1800's and high-grade zones as well, indicating that the highest-grade bonanza mineralization in the area drilled was only partially mined out.
岩心鑽探計劃與大量的金銀礦化相交,見下表,將礦化區延伸到爭奪區露天礦坑以西、東和下方的深度。這些鑽孔還與歷史上的礦牀開採區相交,可能可以追溯到1800年代後期,高品位區域也有,這表明鑽探區域中品位最高的礦化僅部分被開採出來。

Aztec has now completed the seven hole core drilling program. Samples and their collection are controlled by an industry standard conforming QAQC program including insertions of certified standards, blanks and sample duplicates. The samples were regularly shipped to and received by the Bureau Veritas Minerals laboratory in Hermosillo, Mexico for geochemical analysis.
阿茲臺克現已完成七孔岩心鑽探計劃。樣本及其採集由符合行業標準的 QAQC 程序控制,包括插入經過認證的標準、空白和樣本副本。樣本定期運往墨西哥埃莫西約的必維礦業實驗室並由其接收,用於地球化學分析。
Core samples are sawn and are continuously collected over 5 foot (1.52m) sample intervals from all drill holes. The samples were analyzed for gold with a 30-gram sample size using the fire assay method FA430 followed by multi-element MA300, including silver. Over limits, when present, are analyzed by MA370 or FA530. All holes contain certified blanks, standards, and duplicates as part of the quality control program.
岩心樣品是鋸成的,並在 5 英尺(1.52 米)的間隔內從所有鑽孔中連續採集樣品。使用火焰分析方法 FA430 對樣本進行了樣本量爲 30 克的黃金,然後使用包括銀在內的多元素 MA300 進行了分析。如果存在超限值,則由 MA370 或 FA530 進行分析。作爲質量控制程序的一部分,所有孔都包含經過認證的空白、標準和重複品。
Tombstone 2023 Core Drill Program Plan Map
Tombstone 2023 巖芯鑽探計劃計劃地圖
The drilling program was designed with data obtained from surveys and modelling completed over 2022, following the conclusion of Aztec's previous RC drilling program in late 2021. Aztec has recently completed an ortho-topographic drone survey to construct detailed maps, surveyed all drill hole collars from 2020-21, sampled for Terraspec alteration analysis half of the North Contention pit, completed Terraspec analysis on all the 2020-21 RC chips, and advanced the construction of a wire-frame 3-D Leapfrog model of the historic, extensive, underground mine workings, with drilling, mineralization, geology, alteration, geophysics, and multi-element geochemistry.
繼阿茲臺克先前的RC鑽探計劃於2021年底結束之後,該鑽探計劃是根據從2022年完成的調查和建模中獲得的數據設計的。阿茲臺克最近完成了用於繪製詳細地圖的正交地形無人機測量,對2020-21年度的所有鑽孔項圈進行了採樣,對北方爭鬥坑的一半進行了Terraspec改造分析,完成了對所有2020-21年RC芯片的Terraspec分析,並推進了具有歷史性、廣泛的地下礦山作業的線框三維 Leapfrog 模型的構建,包括鑽探、礦化、地質學、蝕變、地球物理學,以及多元素地球化學。
To date the review of exploration data has defined the following target types for exploration at Tombstone:
迄今爲止,對勘探數據的審查已確定了以下在Tombstone進行勘探的目標類型:
- Shallow, bulk tonnage, "heap leachable"-type mineralization typical of Tombstone, composed of mesothermal Au-Ag oxides associated with the enrichment of sediment hosted mineralization on favorable horizons and structures, and with crosscutting, mineralized Qfp dikes and sills, mesothermal veins and hydrothermal breccias. This is the target type of Aztec's exploration focus since 2019.
- Sub-water table (below ~200m depth) extensions of the typical Tombstone Au-Ag mineralization, composed mostly of secondary enrichment minerals and focused by the same horizon and structure types as the extensively mined shallow deposits above.
- Deeper, high grade, "Taylor"- style carbonate replacement silver-lead-zinc-copper-gold deposits (CRD) in the extensive carbonate section (~ 2 kms estimated thickness) below the Bisbee formation.
- The potential for a mineralized porphyry-type deposit as a source of the Tombstone mineralization.
- 淺層、散裝噸位、“堆可滲出” 型 Tombstone的典型礦化由與沉積物富集相關的中溫金銀氧化物組成,在有利的地平線和結構上託管礦化,以及橫切的、礦化的Qfp堤壩和石倉、中溫靜脈和熱液角礫岩。這是自2019年以來阿茲臺克人探索重點的目標類型。
- 地下水位(約 200 米深度以下) 典型的墓石金銀礦化的延伸部分,主要由二次富集礦物組成,其地平線和結構類型與上面廣泛開採的淺層礦牀相同。
- 更深、更高等級、“泰勒” 式的碳酸鹽替代品 比斯比地層下方廣闊的碳酸鹽部分(估計厚度約爲2千米)中的銀-鉛-鋅-銅-金礦牀(CRD)。
- 礦化斑岩型的潛力 礦牀是墓碑礦化的來源。
Data obtained from the core drill holes is expected to supplement the previous, shallow RC drilling by providing extensive knowledge of geological relationships and testing at the depth of the water table and below the Contention system across its width and along its length. Notably, Aztec's previous drilling terminated above the water table where typically the enrichment of Ag occurs, and that the main host horizons of the Tombstone district are found at this depth in the Contention target.
預計從岩心鑽孔獲得的數據將提供有關地質關係的廣泛知識,並在地下水位深度和Contation系統下方的寬度和長度上進行測試,從而補充之前的淺層鋼筋混凝土鑽探。值得注意的是, 阿茲臺克人先前的鑽探在地下水位上方終止,銀的富集通常發生在那裏,而且 Tombstone 地區的主要宿主視野位於爭奪目標的這個深度。
Upon the completion of diamond drilling, Aztec plans additional work including:
鑽石鑽探完成後,阿茲臺克計劃進行更多工作,包括:
- Examining multi-element results for correlative, spatial, and geologic relationships.
- Terraspec analysis of the drill core.
- Detailed mapping of the Contention Open Pit, accompanied with Terraspec.
- Update the drilling data into the Leapfrog model, and update known district drilling, geology (lithology, structural, alteration, mineralogy, mineralization age-dating), geophysics, geochemistry, and UG workings to identify mineralization trends to help target the shallow and deep-CRD drilling.
- Examine the possibility of using seismic geophysics for identifying the overthrusts, faults and folding in the carbonates at depth.
- A potential 43-101 compliant resource estimation
- 檢查多元素結果中的相關關係、空間和地質關係。
- Terraspec 對鑽芯的分析。
- Contention 露天礦坑的詳細地圖,附有 Terraspec。
- 將鑽探數據更新到 Leapfrog 模型中,並更新已知的區域鑽探、地質學(巖性學、結構學、蝕變、礦物學、礦化年齡年代測定)、地球物理學、地球化學和 UG 工作,以確定礦化趨勢,幫助瞄準淺層和深層CRD鑽探。
- 研究使用地震地球物理學來識別深度碳酸鹽巖的超推力、斷層和摺疊的可能性。
- 可能符合 43-101 標準的資源估算
Tombstone Project Overview
Tombstone 項目概述
The main target of the 2023 core drill program is to continue testing the shallow, bulk tonnage, heap leachable, mesothermal gold-silver oxide mineralization adjacent and below the previously mined Contention pit by infill and step-out drilling. Future drilling is expected to focus on strike and dip extensions of the shallow oxide mineralization, and move deeper to test for larger, deeper "Taylor-type" CRD targets along and adjacent to the Contention structure.
2023 年岩心鑽探計劃的主要目標是通過填充和跨步鑽探,繼續測試先前開採的 Contention 礦坑附近和下方的淺層、散裝噸位、堆可滲出、中溫金銀氧化物礦化層。預計未來的鑽探將側重於淺層氧化物礦化的走向和向下延伸,並向更深的方向移動,以測試Contention結構沿線和附近更大、更深的 “泰勒型” CRD目標。
The Tombstone project is located 100 kilometers (km) southeast of Tucson, Arizona and covers much of the historic Tombstone silver district. Tombstone is renowned for its high grade, oxidized, silver-gold-lead-zinc-copper mesothermal and CRD mineralization hosted in veins, mantos, pipes and disseminated orebodies that were mined in the late 1800's and early 1900's.
Tombstone項目位於亞利桑那州圖森市東南100千米(km)處,涵蓋了歷史悠久的墓碑銀區的大部分地區。Tombstone 因其在 1800 年代末和 1900 年代初開採的礦脈、曼陀羅、管道和播散礦體中的高品位、氧化銀-金-鉛鋅-銅中溫礦化和 CRD 礦化而聞名。
Host rocks to the mineralization were primarily the clastic sediments of the Cretaceous Bisbee Formation. Below 200 meters (m) in depth, the Bisbee is underlain by the same Paleozoic limestone formations that host the Taylor zinc-lead-silver deposit located 60 km southwest of Tombstone. Taylor was discovered by Arizona Mining in 2015 and they accepted a takeover bid from South32 Limited in 2018.
礦化的宿主岩石主要是白堊紀比斯比組的碎屑沉積物。比斯比河深度低於 200 米(m),位於墓碑西南 60 千米處的泰勒鋅鉛銀礦牀所在的古生代石灰岩地層下方。泰勒於2015年被亞利桑那礦業公司發現,他們於2018年接受了South32 Limited的收購要約。
Although the historic silver mines at Tombstone were generally small, Aztec believes they could be related to much larger mesothermal and CRD orebodies below the old mines. Since 2017, Aztec has completed geological mapping, geochemical sampling and geophysical surveying to identify the most prospective areas for Au-Ag mineralization around and below the Contention open pit, and CRD zinc-lead-copper-silver-gold mineralization below the entire district.
儘管Tombstone的歷史銀礦通常很小,但阿茲臺克人認爲它們可能與舊礦山下方更大的中溫和CRD礦體有關。自2017年以來,阿茲臺克人已經完成了地質測繪、地球化學採樣和地球物理調查,以確定Contention露天礦坑周圍和下方最有前景的金銀礦化區域,以及整個區域下方的CRD鋅-鉛-銅-銀-金礦化區域。
The 2021 drill holes were collared along the western rim and inside of the north and central parts of the Contention Pit and intersected mineralization over a north-south length of 600 meters by over 150 m of east-west width and to maximum depths of 175 m. The 2020 drilling had an area of mineralization of 850 m long by an average of 75 m wide and to maximum depths of 200 m deep. The combined 2020 and 2021 drilled area now spans 900 m long by over 230 m wide and to maximum depths of 200 m, with Au-Ag mineralization still open in all directions and at depth.
2021 年的鑽孔沿着西緣以及爭奪坑的北部和中部內部開採,在南北長 600 米、東西向寬度超過 150 米、最大深度爲 175 米。2020 年鑽探的礦化區域長 850 米,平均寬 75 米,最大深度爲 200 米。2020 年和 2021 年的總鑽探區域現在跨度爲 900 米,寬度超過 230 米,最大深度爲 200 米,金銀礦化在各個方向和深度仍處於開放狀態。
The low sulfidation epithermal gold-silver mineralization observed to date is impressive, marked by hydrothermal breccias, quartz veining and silicification associated with quartz-feldspar porphyry dikes and moderate to strong potassic, argillic and advanced argillic alteration and hornfels within the host Bisbee sandstones and siltstones. Areas of intense hematite, goethite and manganese wad are extensive, associated with quartz-calcite veins and localized skarn alteration in limestones. Cerargyrite (silver chloride) is observed in fractures, often with fine-grained visible gold. Most Au-Ag mineralized zones intersected in the 2020 and 2021 drill programs are proximal to the historic underground mine workings.
迄今爲止觀測到的低硫化超熱金銀礦化作用令人印象深刻,其特徵是與石英長石斑岩堤相關的熱液角礫岩、石英脈紋和硅化以及宿主比斯比砂岩和粉砂岩中的中度至強鉀、針狀和晚期針狀蝕變和角巖。深度赤鐵礦、針鐵礦和錳巖的區域很廣,與石英方解石礦脈和石灰岩中的局部矽卡巖蝕變有關。在骨折中觀察到塞拉吉利特(氯化銀), 通常含有細顆粒的可見黃金。在2020年和2021年鑽探計劃中相交的大多數金銀礦化區都靠近歷史性的地下礦山開採區。

Gold equivalents are calculated using a 80:1 silver:gold ratio in 2020 and 2023 and a 70:1 silver:gold ratio in 2021.Reported lengths are apparent widths, not true widths. The Contention Au-Ag mineralization zones are generally west dipping at around 60-80 degrees, associated with the quartz-feldspar porphyry dikes. However, these dikes also extend as sills in shallow angles out from the Contention fault along fold noses in the Bisbee clastic sediments so the full range of mineralization dips vary from 20 to 80 degrees. True widths for the apparent mineralization intersection widths of the five holes approximately range from 50 to 100% of the apparent widths, with the norm for the mineralized true widths being 60 to 90% of the apparent widths.
黃金等價物是在 2020 年和 2023 年使用 80:1 的銀:金比率和 2021 年使用 70:1 的銀金比率計算得出的。報告的長度是表觀寬度,而不是實際寬度。Contention Au-Ag 礦化區通常位於西部 60-80 度左右,與石英長石斑岩堤有關。但是,在比斯比碎屑沉積物中,這些堤壩也以淺角度從Contation斷層向外延伸出斜坡,因此整個礦化傾角範圍從20到80度不等。五個孔的表觀礦化交叉點寬度的真實寬度大約在表觀寬度的50%至100%之間,礦化實際寬度的標準爲表觀寬度的60%至90%。
Tombstone Project Highlights
Tombstone 項目亮點
- Well located property on patented (33) and unpatented (42) claims (452.02 hectares/1,116.94 acres), covers much of the historic Tombstone silver mining district, great infrastructure, local town, road access, full services, water, power
- Historic silver district produced 32 million oz silver from 1878-1939, in high grade, oxidized, silver-gold-lead-zinc-copper vein and CRD deposits, and small open pit heap leach production in late 1980's
- Drilling by Aztec in 2020-21 has demonstrated that the Contention Pit target has significant Au-Ag mineralization which is open in all directions
- Multiple other prospective targets in Cretaceous and Paleozoic rocks related to major NW and NNE trending structures hosting porphyritic intrusions crosscutting a possible caldera ring structure
- A very important target is a potential bulk-tonnage carbonate replacement deposit in Paleozoic limestones similar to the Taylor discovery (100+ million tonnes of 10% Zinc Equivalent) located 60 km southwest of Tombstone (mineralization hosted on adjacent and/or nearby properties is not necessarily indicative of the mineralization hosted on the Company's property) whose presence is suggested by historic deep drilling intercepts for CRD mineralization returned multiple intersections grading up to 32 gpt silver, 0.61% copper, 6.5% lead and 2.6% zinc over 7.2m core length
- Distinct magnetic and AMT anomalies confirm multiple target areas, Contention pit hosts dikes along strongest district structure, excellent potential for CRD deposits with similar geology to the "Taylor" deposit
- Aztec high-grade surface rock samples from the Contention Pit, grade up to 3,178 gpt silver and 23.5 gpt gold, epithermal stockwork mineralization open along strike. Out of 94 samples collected from within the pit, silver ranges between <0.1 and 3,178 gpt (114.5 gpt average) and gold ranges <0.005 and 23.5 gpt (1.60 gpt average)
- Historic shallow mining at Contention pit for heap leachable Au-Ag mineralization, historic drilling by USMX around the pit returned multiple intersections including 1.61 gpt Au, 91.2 gpt Ag over 44.2m (see the Company's news release dated September 18, 2018 "Aztec Minerals Acquires Late 1980's-Early 1990's Drilling and Trenching Data for the Tombstone Project, Arizona" for further disclosure on USMX drilling)
- 位置優越的房產 根據專利(33)和非專利(42)索賠(452.02 公頃/1,116.94 英畝),涵蓋了歷史悠久的 Tombstone 銀礦區的大部分地區、良好的基礎設施、當地城鎮、道路通道、全套服務、水、電力
- 歷史悠久的銀區 1878-1939 年間生產了 3200 萬盎司白銀,採用高品位、氧化型、銀-金-鉛-鋅-銅礦脈和 CRD 礦牀,在 1980 年代後期還生產了小型露天堆浸出物
- 阿茲臺克人在 2020-21 年度進行鑽探 已證明Contention Pit目標具有顯著的金銀礦化作用,該礦化向四面八方開放
- 其他多個潛在目標白堊紀和古生代岩石中的s與主要 NW 和 NNE 趨勢結構有關,這些結構存在斑岩入侵,橫穿了可能的火山口環狀結構
- 一個非常重要的目標 是古生代石灰岩中潛在的塊狀碳酸鹽替代礦牀,類似於位於墓碑西南 60 千米處的泰勒發現(超過 1 億噸 10% 的鋅當量)(位於鄰近和/或附近地塊上的礦化不一定表示公司財產上存在礦化),其存在是由歷史上的 CRD 礦化深層鑽探截點返回的多個交叉路口,銀分級高達 32 gpt,銅 0.61% 在 7.2 米的核心長度上爲 6.5% 的鉛和 2.6% 的鋅
- 明顯的磁異常和 AMT 異常 確認多個目標區域,Contention pit 在最堅固的區域結構上有堤壩,具有與 “泰勒” 礦牀地質相似的 CRD 礦牀的潛力極大
- 阿茲臺克高等級地表岩石樣本 從爭奪坑出發,等級高達 3,178 gpt 的白銀和 23.5 gpt 的黃金,衝擊沿線開啓了淺熱岩石礦化。在礦坑內採集的 94 個樣本中,銀的範圍在
- 歷史性的淺層採礦 在爭奪堆可滲出金銀礦化的爭奪坑中,USMX 在礦坑周圍進行的歷史性鑽探返回了多個交叉點,包括 1.61 gpt Au、91.2 gpt Ag,超過 442 萬英尺的 GPT Ag(見該公司於 2018 年 9 月 18 日發佈的新聞稿)”阿茲臺克礦業公司爲亞利桑那州墓碑項目收購了1980年代末至1990年代初的鑽探和挖溝數據” 以進一步披露USMX鑽探情況)
