Highlights
亮點
- The 2023 Todd Creek program included one of the largest 3D IP surveys in British Columbia history, completed by Dias Geophysics using their DIAS32 system. The IP survey focused on a 12 km N-S by 3 km E-W highly gossanous corridor on the west side of Todd Creek valley that is host to numerous Cu-Au occurrences over a widespread area. The survey delineated three extensive zones of high chargeability (25-45 mV-V) underlying or in proximity to areas of known Cu-Au mineralization on the property, including: (1) in the Fall Creek - Ice Creek area, (2) west and north of historical drill holes in the Yellow Bowl Zone, and (3) west of the South Zone. The highest chargeabilities were located in the Fall Creek - Ice Creek area where a 2 by 1 km zone (open to the north) wraps around a strong 300 by 800 metre conductor (low-resistivity zone). None of the high chargeability zones and conductors identified in the 2023 IP program have been drill tested.
- Ice Creek Zone - six new rock samples along a 1 km long north-south trend returned gold values in excess of 1 g/t (grams per tonne), including a sample of hydrothermal breccia returning 262 g/t Au (with 2.46% Cu), one of the highest gold values seen to date on the project. Copper values within the trend range up to 3.43%. The Ice Creek Zone is underlain in part by a coincident chargeability (> 35 mV/V)/resistivity (< 250 ohm-m) anomaly with approximate dimensions of 500 m by 800 m. This newly recognized geophysical target with coincident high-grade surface rock samples, is untested by drilling (Fig. 1).
- Fall Creek Zone - prospecting located a breccia dyke between the A and B zones which returned an assay of 1.15 g/t Au, 0.76% Cu and 80 parts per million molybdenum (Mo). Rock samples from the south side of Fall Creek returned assays of 0.039-3.21 g/t Au, 0.31-3.67% Cu and 2.6-22.5 g/t silver (Ag) in an area with only one shallow drill hole. The 2023 geophysical survey has identified a largely untested chargeability anomaly underlying much of the Fall Creek area (Fig. 2).
- Yellow Bowl - Multiple untested chargeability anomalies have been identified beneath variably Cu-Au mineralized, predominantly quartz-sericite-pyrite altered volcanic rocks of the Yellow Bowl target area (Fig. 3). 3D IP results suggest that 2020 drill holes at Yellow Bowl did not test the chargeability anomalies.
- South Zone - A significant (> 30 mV/V) chargeability anomaly has been identified at depth to the west of epithermal Au-Cu lodes of the South Zone and newly recognized advanced argillic alteration (Fig. 4). The chargeability anomaly is untested by drilling.
- A new zone prospective for massive sulfides was discovered (South Ridge Zone) over two km west of the South Zone in a previously unexplored area. An area of QSP alteration over 2 km long contains massive sulfide lenses in siliceous sedimentary rocks overlying intensely QSP altered feldspar-porphyritic tuffs. Rock samples returned up to 3.96% Cu, with soil samples up to 296 ppm Cu.
- Alteration mapping supported by TerraSpec analyses has defined extensive phyllic (muscovite) alteration over a north-south length of 13.5 km and across widths of 2-3.5 km, as well as a number of smaller structurally controlled zones of advanced argillic alteration (pyrophyllite, alunite, diaspore, dickite) in the Yellow Bowl Zone, Pyrophyllite Zone, and west of the South Zone.
- 2023 年 Todd Creek 項目包括不列顛哥倫比亞省歷史上規模最大的三維知識產權調查之一,由 Dias Geophysics 使用 DIAS32 系統完成。知識產權調查的重點是位於託德溪谷西側一條南北長12千米、東經3千米的高棉質走廊,該走廊在廣闊的區域內有許多銅金礦點。該調查在地產上已知的銅金礦化區域下方或附近劃定了三個具有高電荷性(25-45 mV-V)的廣闊區域,包括:(1)福爾克里克-冰溪區域,(2)黃碗區歷史鑽孔的西部和北部,以及(3)南區以西。充電能力最高的地區位於福爾克里克-冰溪地區,那裏的2×1千米區域(向北開放)環繞着一條300 x 800米的堅固導體(低電阻率區域)。 2023 年知識產權計劃中確定的高充電區域和導體均未經過鑽孔測試。
- 冰溪區 -沿着長達1千米的南北趨勢的六個新岩石樣本返回的金值超過1 g/t(克每噸),其中包括一個返回的熱液角礫岩樣本 262 克/噸金(含 2.46% 銅),這是該項目迄今爲止最高的黃金價值之一。銅價在趨勢區間內高達3.43%。Ice Creek Zone 在一定程度上受重合充電能力(> 35 mV/V)/電阻率(
- 秋溪專區 -探礦在 A 和 B 區域之間找到了一個角礫岩堤壩,結果是 1.15 g/t 金、0.76% 銅和百萬分之八十的鉬 (Mo)。在只有一個淺鑽孔的區域,來自福爾克里克南側的岩石樣本返回了0.039-3.21克/噸金、0.31-3.67%的銅和2.6-22.5克/噸的銀(銀)的化驗結果。2023 年地球物理調查發現,福爾克里克地區大部分地區存在一種基本上未經測試的可充電性異常(圖 2)。
- 黃碗 -在黃碗目標區域的可變銅金礦化火山岩下發現了多個未經測試的電荷性異常(圖3)。三維IP結果表明,2020年在Yellow Bowl的鑽孔未測試過電荷異常。
- 南區 -已在南區超熱金銅礦脈以西的深度發現了顯著(> 30 mV/V)的電荷性異常,並發現了新發現的晚期泥質蝕變(圖4)。可充電性異常未經鑽探測試。
- 發現了一個可能存在塊狀硫化物的新區域(南嶺區)位於南區以西兩公里多處,位於以前未開發的地區。長度超過2千米的QSP蝕變區域在硅質沉積岩中含有大量的硫化物透鏡,這些沉積岩覆蓋了強烈的QSP變化長石斑岩凝灰岩。 岩石樣本返回的銅含量高達 3.96%,土壤樣本的銅含量高達 296 ppm。
- TerraSpec 分析支持的變化映射已經定義了廣泛的 在南北長度爲13.5千米和寬度爲2-3.5千米的範圍內(白雲母)變化,以及黃碗區、葉蠟巖區和南區以西的許多較小的結構控制的高級泥質蝕變區(葉蠟巖、明石、水鋁石、迪克石)。
Tyler Ruks, President and CEO of ArcWest commented, "The 2023 Todd Creek exploration program included one of the largest 3D IP surveys in B.C. history. The results of this combined geophysical, geological mapping and geochemical sampling program strengthen our thesis that the Todd Creek property is host to a very large and highly underexplored hydrothermal-magmatic system with potential for the discovery of multiple copper-gold mineralized centres. We are especially excited about the intense chargeability-resistivity anomalies identified at depth in the Ice Creek-Fall Creek areas, where Cu-Au mineralized intercepts in historic core contain previously unrecognized porphyry-like veins and recently recognized, vertically dipping Cu-Mo-Au mineralized breccia dikes contain potential intrusive clasts that have likely been sourced from depth.
ArcWest總裁兼首席執行官泰勒·魯克斯評論說:“2023年託德溪勘探計劃包括不列顛哥倫比亞省歷史上規模最大的三維知識產權調查之一。這項結合的地球物理、地質測繪和地球化學採樣計劃的結果強化了我們的論點,即託德克里克地產是一個非常龐大且開發嚴重不足的熱液岩漿系統,有可能發現多個銅金礦化中心。我們對在Ice Creek-Fall Creek地區深處發現的強烈的電荷電阻率異常感到特別興奮,那裏的歷史核心中的銅金礦化截留物含有以前未被識別的斑岩狀礦脈,最近發現的垂直浸泡的Cu-Mo-Au礦化角礫岩堤中含有潛在的侵入性碎屑,這些碎屑可能來自深處。
"ArcWest thanks the Todd Creek exploration crew, including Charlie Greig and his team, for their exceptional work on the project in 2023. Dias Geophysical deserves special credit for performing one of the most technically challenging geophysical surveys in B.C. history. We thank Freeport for funding such an aggressive ground program in 2023 and look forward to working with Freeport to advance the project in 2024.
“ArcWest感謝託德·克里克的勘探人員,包括查理·格雷格和他的團隊,他們在2023年在該項目上所做的出色工作。Dias Geophysical開展了不列顛哥倫比亞省歷史上技術上最具挑戰性的地球物理調查之一,值得特別讚揚。我們感謝弗裏波特在2023年資助如此激進的地面項目,並期待與弗裏波特合作在2024年推進該項目。
"Despite difficult market conditions, ArcWest remains in a strong financial position with just over $2 million hard dollars in the treasury, zero warrants, significant insider ownership and an exceptionally low burn rate. Anticipated income for ArcWest between now and the end of the year includes option payments totaling $900,000, in addition to share payments from earn-in agreements and operatorship fees for ArcWest managed exploration programs. The company currently has a market capitalization of only $4.15 million. Exploration budgets are being finalized, with potential for third-party funded drilling on multiple 100% ArcWest owned porphyry Cu-Au projects this year."
“儘管市場條件艱難,但ArcWest仍然保持強勁的財務狀況,國庫中的硬美元剛剛超過200萬美元,認股權證爲零,內部所有權豐富,消耗率異常低。從現在起到年底,ArcWest的預期收入包括總額爲90萬美元的期權付款,以及來自收益協議的股份支付和ArcWest管理的勘探計劃的運營費。該公司目前的市值僅爲415萬美元。勘探預算正在敲定,今年有可能在ArcWest擁有的多個斑岩銅金項目上進行第三方資助的鑽探。”
ArcWest's 2023 Todd Creek exploration program, funded by Freeport, was a comprehensive, multidisciplinary effort to delineate drill targets across multiple mineralized zones within the 12 kilometre-long Todd Creek alteration corridor. The 2023 Todd Creek exploration included:
ArcWest的2023年託德溪勘探計劃由弗裏波特資助,是一項全面的多學科項目,旨在劃定12公里長的託德溪蝕變走廊內多個礦化帶的鑽探目標。2023 年 Todd Creek 的勘探包括:

Ice Creek and Fall Creek Zones
冰溪和秋溪區域
The Ice Creek and Fall Creek Zones are underlain primarily by variably altered (chlorite-epidote-pyrite through quartz-sericite-pyrite), locally K-feldspar rich mafic through intermediate/felsic volcanic rocks. Historical drilling in the Ice Creek and Fall Creek Zones included 35 drill holes over a 1.5 by 0.6 km area, with 19 testing high grade epithermal Au-Cu veins (primarily quartz-chalcopyrite-hematite) and breccias north of Fall Creek. Re-logging of select historic Ice Creek core by ArcWest geologists has demonstrated that Cu-Au mineralized intercepts locally contain previously unrecognized, porphyry-like veins. Historical drilling at Ice Creek-Fall Creek tested only shallow targets, with drill holes averaging 132 m in length. Shallow drill intercepts (not true widths) include:
Ice Creek 和 Fall Creek 區域主要由變化可變(亞氯酸鹽-外觀-黃鐵礦穿過石英-蠶絲巖-黃鐵礦)、通過中間/長英質火山岩穿過當地富含鉀長石的鎂鐵質構成。冰溪和福爾溪區的歷史鑽探包括在1.5 x 0.6千米的區域內鑽35個鑽孔,其中19個測試了福爾克里克以北的高品位超成熱金銅礦脈(主要是石英-黃銅礦-赤鐵礦)和角礫岩。ArcWest地質學家對部分歷史悠久的冰溪岩心進行了重新記錄,結果表明,當地的銅金礦化截面含有以前無法識別的斑岩狀礦脈。Ice Creek-Fall Creek的歷史鑽探僅測試了淺層目標,鑽孔的平均長度爲132米。淺鑽截距(非真實寬度)包括:
- 3.47 g/t Au and 0.73% Cu over 31.85m (88-22, Fall Creek "A Zone", 29.3-61.15m)
- 0.60 g/t Au and 0.25% Cu over 15.48m (NEZ07-01, Fall Creek "B Zone", 51.91-67.39m)
- 1.78 g/t Au and 0.55% Cu over 20.95m (88-47, Ice Creek, 28.7-49.65m)
- 3.47 g/t Au 和 0.73% Cu 超過 3185 米(88-22,Fall Creek “A 區”,293-61.15 米)
- 金含量爲 0.60 克/噸,銅含量超過 1548 米(NEZ07-01,Fall Creek “B 區”,51.91-67.39 米)
- 1.78 g/t Au 和 0.55% Cu 超過 2095 米(88-47,Ice Creek,28.7-49.65 米)
The 2023 3DIP survey outlined a strong IP chargeability anomaly beneath most of the shallow Ice Creek and Fall Creek drilling (Fig. 1). The >25 mV/V anomaly is over 2 km long and up to 1.5 km wide and open to the north toward the Orange Mountain Zone. Within this large anomaly, higher chargeability zones (>35 mV/V) flank a strong conductor (resistivities <250 ohm-m). The largest >35 mV/V anomaly is about 500 by 800 m and is located at depth between the Fall Creek A Zone and a shallow Ice Creek drill intercept in NTC88-46 (1.07 g/t Au and 0.13% Cu over 19.25m, 32.5-51.75m).
2023 年 3DIP 調查概述了大多數淺層冰溪和福爾溪鑽探下方的強烈知識產權收費異常(圖 1)。>25 mV/V 的異常長度超過 2 千米,寬度可達 1.5 千米,向北向奧蘭治山區開放。在這個較大的異常狀態中,更高的可充電區域(>35 mV/V)位於強導體(電阻率35 mV/V 的最大異常約爲 500 x 800 米,位於 Fall Creek A 區域和 NTC88-46 淺冰溪鑽探截距之間的深度(19.25米、32.5-51.75 米上方爲 1.07 g/t Au 和 0.13% 銅含量 0.13%)。
Prospecting east of the A Zone on the north side of Fall Creek in 2023 discovered a significant, well-mineralized polymictic matrix supported breccia dyke. The breccia dyke contains sand to fist-sized angular clasts of quartz, felsic volcanic, possible shallow intrusive rock, altered porphyritic volcanic and wall rock andesite in a sulfide-rich matrix. A character sample of the breccia dyke returned the following assay:
2023 年,在 Fall Creek 北側 A 區以東進行勘探,發現了一個重要的、礦化良好的多晶基質支撐角礫岩壩。角礫岩堤壩含有沙子到拳頭大小的角形石英碎片、長英質火山岩、可能的淺層侵入性岩石、變質斑岩火山和富含硫化物的基質中的壁巖安山岩。角礫岩堤的字符樣本返回了以下化驗結果:

(金-金;銅——銅;鉬——鉬;銀——銀;g/t——克每噸;ppm——百萬分之一;NAD83,UTM 9區)。
The high Cu-Mo-Au values and diverse suite of clasts, including possible intrusive clasts, is significant in providing a possible link between the shallow epithermal Au-Cu mineralization in the Fall Creek Zone and a buried porphyry system.
Cu-Mo-Au值高,碎屑種類繁多,包括可能的侵入性碎屑,在爲Fall Creek區的淺層超熱Au-Cu礦化與埋藏斑岩系統之間提供了可能的聯繫非常重要。
South of Fall Creek, a series of samples returned elevated Cu and Au values in an area with only one 109m drill hole (NTC90-049). Samples L615418 and L615082 are on strike with the A Zone and likely represent its continuation south of Fall Creek. Sample L615074 is one of the easternmost samples of mineralization in the Fall Creek Zone, and its elevated Mo value is noteworthy. Sample L615082 is of a vertically dipping, 1 m wide quartz vein with margins that are well mineralized with chalcopyrite. A chargeability anomaly underlies much of the Fall Creek area and remains largely untested by drilling (Fig. 2).
在福爾克里克以南,在只有一個109米鑽孔(NTC90-049)的區域,一系列樣本返回了較高的銅和金值。樣本 L615418 和 L615082 正在 A 區進行罷工,很可能代表其延伸到福爾克里克以南。L615074 樣本是福爾溪區最東端的礦化樣本之一,其鉬值升高值得注意。L615082 樣品是一條垂直浸泡、寬 1 米的石英礦脈,其邊緣由黃銅礦礦化得很好。可充電性異常是福爾克里克地區大部分地區的基礎,而且在很大程度上仍未通過鑽探進行測試(圖 2)。

In the Ice Creek area, prospecting in 2023 followed up on a 2019 discovery of high-grade Cu-Au-Ag-Mo mineralization (sample S848583: 2.77 g/t Au, 3.43% Cu, 23.8 g/t silver and 201 ppm molybdenum), part of a previously unknown northwest trending zone of mineralization over 1 km strike length, which is located west of historical drilling. Notably, significant Mo enrichment is present in multiple samples from the area.
在 Ice Creek 地區,2023 年的勘探是在 2019 年發現的高品位銅-金-銀鉬礦化(樣本 S848583:2.77 g/t Au、3.43% Cu、23.8 g/t 銀和 201 ppm 鉬)的後續勘探,該礦化區位於歷史鑽探以西,走向長度超過 1 千米,是以前未知的西北礦化趨勢帶的一部分。值得注意的是,該地區的多個樣本中存在大量的鉬富集。

Sample L615119, returning an assay of 262 g/t Au and 2.46% Cu, is from a sulfide-rich matrix supported hydrothermal breccia located over the central part of the southern lobe of the large Ice Creek - Fall Creek chargeability high, and is one of the highest grade gold assays from the project area to date. The underlying, newly recognized geophysical anomaly remains untested by drilling.
L615119 樣本返回了 262 g/t Au 和 2.46% Cu的化驗結果,來自富含硫化物的基質支撐的熱液角礫岩,位於大型冰溪——福爾克里克電荷性高,是該項目區域迄今爲止最高等級的金分析之一。新發現的潛在地球物理異常仍未通過鑽探進行測試。
Sample J00389 is from a vein located 300m south of the southernmost drill intercept at Ice Creek, NTC90-56 (0.13 g/t Au 0.253% Cu over 19.1m; 51.55-70.65m). Previous rock sampling by P2 Gold in 2021 had returned a number of significant Au and Cu assays in this area (see ArcWest news release January 20, 2022).
J00389 樣本來自位於 NTC90-56 Ice Creek 最南端鑽探截距以南 300 米處的一條礦脈(19.1 米以上 0.13 g/t Au 0.253% Cu;51.55-70.65 m)。P2 Gold先前在2021年進行的岩石採樣已在該區域返回了許多重要的金和銅化驗結果(見ArcWest於2022年1月20日發佈的新聞稿)。

Yellow Bowl Zone
黃碗區
The Yellow Bowl Zone is the largest and most prominent gossan in the Todd Creek corridor, containing widespread Cu and Au mineralization over an 800 by 600 m area. The geology of the zone is complex, but primarily comprises variably altered (chlorite-epidote-pyrite through quartz-sericite-pyrite/local advanced argillic), locally K-feldspar rich mafic through intermediate/felsic volcanic rocks. At the south end of the zone, local breccia dykes are present, containing chlorite-epidote-pyrite altered coarsely porphyritic intrusive clasts with local quartz-pyrite+/-chalcopyrite and pyrite veins. Despite its size, to date the Yellow Bowl Zone has been tested by only two drill holes in 2020. The 2023 IP survey delineated a significant chargeability anomaly (25-40 mV/V) extending for over two km along a northeasterly trend, crosscutting geological contacts, beneath the Yellow Bowl Zone (Fig. 3). The anomaly is over 500 m wide and its southeast margin (>25 mV/V) lies west of the 2020 drill holes which failed to test it. Importantly, the most notable drill intercept from the 2020 Todd Creek drill program is from the part of Yellow Bowl drill hole TC20-02 (0.78% Cu 84 ppb Au over 14.05m from 330m depth) that is closest to this newly recognized, untested geophysical anomaly, suggesting a potential genetic relationship. Drill testing of this chargeability anomaly is therefore recommended in order to test this thesis.
黃碗區是託德溪走廊中最大、最顯著的岩石,在 800 x 600 米的區域內有廣泛的銅和金礦化區。該區域的地質很複雜,但主要包括變化不定(通過石英-蠶絲巖-黃鐵礦/局部高級泥土)、通過中間/長英質火山岩獲得的局部富含鉀長石的鎂鐵質巖。在該區域的南端,存在局部角礫岩堤,其中含有亞氯酸鹽-表觀-黃鐵礦改性的粗斑狀侵入性碎片,局部有石英-黃鐵礦+/-銅礦和黃鐵礦脈。儘管規模很大,但到目前爲止,黃碗區在2020年僅經過兩個鑽孔的測試。2023年知識產權調查在黃碗區下方沿東北方向延伸了超過兩千米的重大可充電性異常(25-40 mV/V),橫穿地質接觸點(圖 3)。該異常寬度超過500米,其東南緣(>25 mV/V)位於未能對其進行測試的2020年鑽孔以西。重要的是,2020 年 Todd Creek 鑽探計劃中最引人注目的鑽探截獲來自黃碗鑽孔 TC20-02(從 330 米深度超過 14.05 米,0.78% Cu 84 ppb Au)中最接近這一新發現的、未經測試的地球物理異常,這表明存在潛在的遺傳關係。因此,建議對這種可充電性異常進行鑽孔測試,以檢驗本論點。
TerraSpec-based alteration studies confirmed the presence of advanced argillic alteration (pyrophyllite, alunite) over about 500 km strike length along a prominent fault marking the southeast side of the Yellow Bowl Zone. Most of the zone is characterized by white mica (quartz-sericite-pyrite or QSP) alteration with high crystallinities, indicating higher temperature hydrothermal fluids and a potential vector to porphyry Cu-Au mineralization
基於TerraSpec的蝕變研究證實,沿着標誌着黃碗區東南側的突出斷層,存在長度約500千米的晚期泥質蝕變(葉蠟巖、明石)。該區域的大部分特徵是具有高結晶度的白色雲母(石英-絹雲母-黃鐵礦或 QSP)蝕變,這表明熱液流體溫度升高,是斑岩銅金礦化的潛在載體
South Zone
南區
The South Zone was the main focus of shallow historical drilling at Todd Creek, with 48 drill holes averaging 128 metres length. Epithermal Au-Cu mineralization of the South Zone comprises quartz-chalcopyrite+/-hematite veins and associated breccias, hosted primarily by mafic to intermediate volcanic rocks and potential high-level intrusions. 2023 petrography indicates that variably quartz-sericite-pyrite overprinted host rocks at South Zone can be K-feldspar rich, and that hematite associated with quartz-chalcopyrite veins and breccias in the zone is at least locally after hydrothermal magnetite. Secondary K-feldspar alteration is also locally present as selvages to quartz-chalcopyrite-hematite veins. This, coupled with the presence of relict hydrothermal magnetite with chalcopyrite, is suggestive of relict potassic alteration. Potential therefore exists down-plunge of west dipping Cu-Au mineralization of the South Zone for the discovery of a porphyry Cu-Au system. The 2023 Todd Creek IP survey identified a prominent chargeability anomaly west of South Zone. The eastern margin of this 500-750 m wide and 2 km long, >25 mV/V anomaly is located about 400 metres west of the South Zone and has never been tested by drilling (Fig. 4).
南區是託德溪歷史淺層鑽探的主要重點,共有48個鑽孔,平均長度爲128米。南區的超熱金銅礦化包括石英-黃銅礦+/-赤鐵礦脈和相關的角礫岩,主要由鎂鐵質到中等火山岩和潛在的高層侵入物構成。2023 年岩石學表明,南區可變的石英絲綢-黃鐵礦疊印主巖可能富含鉀長石,與石英-黃銅礦脈相關的赤鐵礦和該區域的角礫岩至少位於熱液磁鐵礦之後的局部區域。繼發性 K-Feldspar 變化也以石英-黃銅礦-赤鐵礦脈的殘渣形式在局部出現。再加上殘留的含黃銅礦的熱液磁鐵礦的存在,都表明殘留的鉀發生了變化。因此,南區存在向西傾覆的銅金礦化向下傾斜的潛力,有可能發現斑岩銅金系統。2023 年 Todd Creek 知識產權調查發現,南區以西存在明顯的收費異常。這個寬500-750米、長2千米、>25 mV/V的異常地的東部邊緣位於南區以西約400米處,從未通過鑽探進行過測試(圖4)。
Prospecting in 2023 identified a new zone of intense advanced argillic alteration (alunite, pyrophyllite, diaspore, dickite) which overlies the eastern end of the chargeability high, about 500 metres west of South Zone. The small alteration zone is located at the intersection of the chargeability anomaly with a prominent north-south low resistivity anomaly (conductor). The narrow conductor extends for about 2.6 km to the north.
2023年的勘探發現了一個新的劇烈晚期泥質蝕變區域(明石、葉蠟巖、水鋁石、二硝石),該區域覆蓋了可充電性高度的東端,位於南區以西約500米處。小變化區位於可充電性異常與明顯的南北低電阻率異常(導體)的交匯處。狹窄的導體向北延伸約2.6千米。
South Ridge Zone
南嶺區
A new discovery in 2023 by Dias Geophysical, the South Ridge Zone is located about two km west of South Zone in an area that had received no historical prospecting or sampling. The zone is on a prominent gossanous ridge with outcropping massive sulfides in a highly prospective sedimentary unit overlying intensely QSP altered feldspar-porphyritic tuffs. Overlying rocks include well bedded silicious mudstones with disseminated pyrite and pyrite laminations, and basalt and siliceous mudstones with hyaloclastite, indicating a highly prospective environment for volcanogenic massive sulfides. A single line of soils along the ridge returned anomalous copper (to 287 ppm), zinc (to 834 ppm), gold (to 42 ppb), arsenic (to 324 ppm) and antimony (to 20 ppm) with anomalous samples over 1.5 km. Two character rock samples (L615102 and L615104) of the sulfide mineralization returned elevated Cu and Au values.
Dias Geophysical在2023年發現了一項新發現,南脊區位於南區以西約兩公里處,該地區沒有經過任何歷史勘探或取樣。該區域位於一個突出的棉質山脊上,在一個極具前景的沉積單元中露出塊狀硫化物,上面覆蓋着強烈的 QSP 變化的長石斑岩凝灰岩。上覆岩石包括具有浸染黃鐵礦和黃鐵礦層狀的層狀良好的硅質泥岩,以及帶有透明質巖的玄武岩和硅質泥岩,這表明火山成因塊狀硫化物的環境前景看好。山脊沿線的一條土壤返回了異常的銅(至287 ppm)、鋅(至834 ppm)、金(至42 ppm)、砷(至324 ppm)和銻(至20 ppm),異常樣本超過1.5 km。硫化物礦化的兩個特徵岩石樣本(L615102 和 L615104)返回了較高的銅和金值。

質量控制
Rock samples were collected from altered and mineralized zones in order to define the character, overall tenor and potential of these zones. The samples comprise representative grabs from outcrops. Grades of grab samples are not necessarily representative of grades of larger rock volumes.
岩石樣本是從變化和礦化區域採集的,目的是確定這些區域的特徵、總體主旨和潛力。這些樣本包括露頭的代表性採集物。抓取樣品的等級不一定代表較大岩石體積的等級。
Rock samples were collected in plastic sample bags and sealed with plastic zip ties. Sample locations and other data were recorded in Qfield, the field component of QGIS. Soil samples were collected in standard Kraft paper bags using Geotools, and hand sorted to remove pebbles. Sampling targeted B horizon soils where available. Soil samples were pre-dried prior to shipping. All samples were bundled in security sealed rice bags and trucked to Bandstra Transportation Systems in Terrace, B.C. and from there trucked to ALS Global's North Vancouver lab facility.
岩石樣本採集在塑料樣品袋中,並用塑料拉鍊封閉。樣本位置和其他數據記錄在QGIS的現場組件Qfield中。使用Geotools在標準的牛皮紙袋中採集土壤樣本,然後進行手工分類以去除卵石。在可能的情況下,對目標地平線土壤進行採樣。土壤樣本在發貨前已預先乾燥。所有樣本都捆綁在安全密封的米袋中,然後用卡車運送到位於不列顛哥倫比亞省特雷斯的Bandstra運輸系統,然後從那裏用卡車運到ALS Global的北溫哥華實驗室設施。
At the laboratory, the samples were dried, crushed and pulverized using standard rock and soil preparation procedures. The pulps were then analyzed for Au using a 30 gram fire assay with ICP-AES finish and for 48 elements by ICP-AES using ALS's Ultra-trace method ME61L. Four acid digestion was utilized for the ICP analyses. Quality control at the laboratory is maintained by submitting blanks, standards and re-assaying duplicate samples from each analytical batch. Due to the reconnaissance nature of the sampling, no external blanks or standards were submitted.
在實驗室,使用標準的岩石和土壤製備程序對樣品進行乾燥、粉碎和粉碎。然後,使用經過ICP-AES表面處理的30克火法對紙漿進行了金分析,並使用ALS的Ultra-Trace方法 ME61L 對紙漿進行了48種元素的分析。ICP 分析使用了四種酸消化。實驗室的質量控制是通過提交空白、標準和重新分析每批分析的重複樣本來維持的。由於抽樣的偵察性質,沒有提交任何外部空白或標準。
Dias Geophysical Limited of Saskatoon Saskatchewan was contracted to conduct the 3D DC-resistivity and induced polarization (DCIP) survey using the DIAS32 acquisition system, in conjunction with one Dias GS5000 25 kW transmitter. The DCIP survey was completed using a rolling distributed 3D array with a pole-dipole transmitter configuration. Data processing was carried out by Dias using two sets of unconstrained 3D inversion models of resistivity and chargeability from the final processed data sets. The resulting models were gridded and trimmed using Geosoft Oasis software and then converted into the UBC-GIF Tensor Mesh format. The DC model is expressed in Ohm-m (resistivity model) and Siemens (conductivity model) and the IP model in mV/V. Deliverables included the station grid coordinates, the XYZ point cloud of apparent resistivity and chargeability data, and a set of unconstrained 3D inversion models in Voxel and UBC formats. The 3D models delivered by Dias were viewed using Mira Geoscience's free Geoscience Analyst software.
