岩土工程工作的重點是收集更多數據,以更好地描述吉拉集團的實力,以支持拒絕進入範戴克礦牀的最新計劃。岩土工程工作計劃將由Call & Nicholas Inc. 完成,以確定是否需要更多數據來支持地下開發的初步可行性研究(“PFS”)級研究。礦物溶解度測試工作的亮點是:

Highlights

亮點

  • Copper recoveries ranged from 8.6% to 96.5% (average 65.1%) in the Oxide zone and from 11.7% to 72.2% (average 30.4%) in the Transition zone within the 72-hour leach period.
  • Recoveries for acid soluble copper ('ASCu') ranged from 28.9% to 98.0% (average 81.5%) in the Oxide zone and from 27.1% to 97.1% (average 59.4%) in the Transition zone within the 72-hour leach period.
  • Recoveries for cyanide soluble copper ('CNCu') ranged from 0.0% to 72.0% (average 25.1%) in the Oxide zone and from 0.7% to 37.2% (average 20.8%) in the Transition zone. The CNCu recoveries in some samples exceed the expected recovery from CNCu soluble copper minerals. The reason for the excess CNCu recovery, while positive, is being investigated.
  • Pregnant Leach Solution ('PLS') grades ranged from 0.19 g/l to 15.30 g/l copper. PLS copper grades are a function of higher total ASCu and CNCu concentrations.
  • Call & Nicholas Inc. has been retained to complete the planned geotechnical program.
  • 在72小時浸出期內,氧化區的銅回收率從8.6%到96.5%(平均65.1%)不等,過渡區的銅回收率從11.7%到72.2%(平均30.4%)不等。
  • 在72小時浸出期內,氧化區的酸溶性銅(“AsCu”)的回收率從28.9%到98.0%(平均爲81.5%)不等,過渡區的回收率從27.1%到97.1%(平均59.4%)不等。
  • 氧化物區的氰化物可溶性銅(“CNCu”)的回收率從0.0%到72.0%(平均25.1%)不等,過渡區的回收率從0.7%到37.2%(平均20.8%)不等。一些樣品中的氯化銅回收率超過了從CNCu可溶性銅礦物的預期回收率。CNCu回收率過高的原因雖然呈陽性,但正在調查中。
  • Pregent Leach Solution(“PLS”)的銅等級從0.19克/升到15.30克/升不等。PLS 銅的等級與 asCu 和 CnCu 的總濃度升高有關。
  • Call & Nicholas Inc. 已獲聘完成計劃中的岩土工程項目。

Elmer B. Stewart, President and CEO of Copper Fox stated, "The recent permitting and financing of the Florence Copper Project, located in Florence, Arizona by Taseko Mines Limited, is considered a significant event for other ISCR projects in Arizona, congratulations to Taseko. The test results for our Van Dyke copper project are positive and encouraging, indicating rapid solubility of the acid soluble copper minerals and enhanced solubility of the cyanide soluble copper minerals within the 72-hour leach period. The acid soluble and cyanide soluble copper that was not recovered within the 72-hour leach period is expected to be recovered over a longer leaching period as is expected in the in-situ leaching process."

Copper Fox總裁兼首席執行官埃爾默·斯圖爾特表示:“Taseko Mines Limited最近對位於亞利桑那州佛羅倫薩的佛羅倫薩銅業項目的許可和融資被視爲亞利桑那州其他ISCR項目的重大事件,恭喜Taseko。我們的 Van Dyke 銅礦項目的測試結果積極且令人鼓舞,表明酸溶性銅礦物在 72 小時浸出期內可快速溶解,氰化物可溶性銅礦物的溶解度得到提高。在72小時浸出期內未回收的酸溶性和氰化物可溶性銅預計將在更長的浸出期內回收,正如在原位浸出過程中所預期的那樣。”

Van Dyke Deposit

Van Dyke 存款

The thickness of the "leach cap" overlying the Van Dyke oxidized copper deposit is characterized by variable concentrations of clay, hematite, limonite, jarosite and goethite, and typically contains less than 100 parts per million ('ppm') copper and ranges in thickness across the deposit. The Van Dyke copper deposit consists of three distinctive mineralogical zones: an upper Oxide zone (primarily malachite. azurite, chrysocolla and native copper (possibly cuprite)) underlain by a Transition zone (primarily chalcocite with lesser malachite, chrysocolla and azurite) underlain by the primary sulphide zone (primarily chalcopyrite with lesser concentrations of chalcocite and bornite).

覆蓋範戴克氧化銅礦牀的 “浸出蓋” 的厚度以粘土、赤鐵礦、褐鐵礦、鐵礦和針鐵礦的濃度不同爲特徵,通常含有少於百萬分之100('ppm')的銅,整個礦牀的厚度各不相同。Van Dyke 銅礦牀由三個獨特的礦物學區域組成:上部氧化物帶(主要是孔雀石、藍銅礦、硅孔雀石和天然銅(可能是銅礦)),其下方是初級硫化物帶(主要是硫銅礦,含較少孔雀石、硅孔雀石和藍銅礦),位於初級硫化物帶(主要是黃銅礦,硫化石和硼礦濃度較低)。nite)。

Mineral Solubility Testwork

礦物溶解度測試工作

Understanding the chemical and mineralogical changes that occur from the initial injection of the leaching solution until recovery of the copper bearing leaching solution (referred to as the PLS) is a fundamental aspect of ISCR projects. The 65 samples selected for mineralogical/mineral solubility testwork were collected from drillholes within the Phase I mine plan set out in the 2021 Preliminary Economic Assessment ('PEA'). The samples are from the Oxide and Transitional zones and cover the mineralized envelope within the selected drillholes at various acid soluble copper and cyanide soluble copper grade classes. The results of the solubility testwork (bottle roll tests) are outlined in Table-1 and Table-2 below. The copper recovery and final PLS copper grades at the end of the 72-hour leach period show a strong correlation to TCu grade.

了解從首次注入浸出溶液到回收含銅浸出液(簡稱 PLS)所發生的化學和礦物學變化是 ISCR 項目的基本方面。被選用於礦物學/礦物溶度測試工作的65個樣本是從2021年初步經濟評估(“PEA”)中規定的第一階段採礦計劃中的鑽孔中收集的。樣品來自氧化物和過渡區,覆蓋了選定的不同酸溶性銅和氰化物可溶性銅等級的鑽孔內的礦化包膜。下表1和表2概述了溶解度測試工作(瓶卷測試)的結果。72 小時浸出期結束時的銅回收率和最終 PLS 銅品位與 tCu 品位有很強的相關性。

Notes: TCu=total copper content in sample; PLS=leach solution; g Cu/l= grams of copper contained in 1 liter of leach solution (PLS); ASCu=acid soluble copper; CNCu=cyanide soluble copper.

注意事項: tcu=樣品中的總銅含量;pls=浸出溶液;g cu/L = 1 升浸出溶液 (PLS) 中所含的銅克數;ascu=酸溶性銅;CNCU=氰化物可溶性銅。

It is expected that the remainder of the copper contained in the acid soluble copper minerals (malachite, azurite, chrysocolla, cuprite) with additional copper recovery from chalcocite would be recovered over a longer leach period as is typical in ISCR operations.

預計酸溶性銅礦物(孔雀石、藍銅礦、硅孔雀石、銅礦)中所含的剩餘銅以及從硫化石中額外回收的銅將在更長的浸出期內回收,這在ISCR業務中很常見。

Geotechnical Program

岩土工程項目

The development of the Van Dyke copper project contemplates access by way of a decline to a depth of approximately 30-40 meters above the Gila Conglomerate/leach cap contact and advancing an underground ramp in the Gila Conglomerate above the leach cap overlying the Van Dyke deposit. The planned geotechnical program consists of logging of the Gila Conglomerate in six drillholes to collect geomechanical and structural orientation data for ground support analyses and decline and ramp design, identify potential areas of concern and to assist with geotechnical domaining and evaluate ground support requirements. The data to be collected includes Rock quality designation ('RQD'), Fracture frequency, Q` data - joint number ('Jn'), joint roughness ('Jr'), and joint alteration ('Ja'), and Hardness '(ISRM') on broken and whole core. Previously collected acoustic televiewer data ('ATV') from the six drillholes will be reviewed to support the geochemical data.

範戴克銅礦項目的開發考慮通過下降到吉拉集團/利奇蓋板接觸點上方約30-40米的深度,然後在覆蓋範戴克礦牀的滲濾蓋上方推進吉拉集團的地下坡道。計劃中的岩土工程計劃包括在六個鑽孔中記錄Gila Conglomerate,以收集地質力學和結構方向數據,用於地面支護分析和坡道設計,確定潛在的關注區域,並協助進行岩土工程劃分和評估地面支撐需求。要收集的數據包括岩石質量標識('RQD')、斷裂頻率、Q`數據——接頭數('Jn')、接頭粗糙度('Jr')和接頭變化('Ja'),以及破碎和整個岩心上的硬度(ISRM)。將對先前從六個鑽孔收集的聲學電視監視器數據(“ATV”)進行審查,以支持地球化學數據。

On completion of the planned testing program, a data gap evaluation will be completed for all available geotechnical and hydrogeological data from the Van Dyke project to determine if additional data is needed to support a PFS level study.

計劃中的測試計劃完成後,將對來自Van Dyke項目的所有可用岩土工程和水文地質數據完成數據差距評估,以確定是否需要更多數據來支持PFS水平研究。

Analytical Procedures

分析程序

The mineral solubility/mineralogical testwork (QEMSCAN) was completed by Base Met Labs US LTD ('BML') located in Tucson, Arizona and at BML's Kamloops, British Columbia facility. Sample preparation for the mineral solubility (bottle roll) tests consisted of stage crushing 100 percent of the sample to passing 10 mesh (1.70 mm) and split into 1-kilogram test samples. The prepared samples were then subjected to a 72-hour leach period, evaluating copper recovery and acid consumption under the following leaching conditions: 1) 45 % Solids, 2) 1.8 pH (adjusting pH every day to make sure free acid is available for leaching), 3) sampling of the pregnant leach solutions ('PLS') at 2,4,6,8,24,48 and 72 hours, 4) the PLS was analyzed for Cu, Fe, pH, ferrous iron (Fe++) and ferric iron (Fe+++). A 50-gram sample from each leached residue was submitted for Cu, Fe and SeqCu analysis.

礦物溶解度/礦物學測試工作(QEMSCAN)由位於亞利桑那州圖森市和不列顛哥倫比亞省坎盧普斯的Base Met Labs US LTD(“BML”)完成。礦物溶解度(瓶卷)測試的樣品製備包括將樣品的 100% 分段粉碎至通過 10 目(1.70 mm),然後分成 1 千克的測試樣品。然後,對製備的樣品進行 72 小時的浸出期,評估以下浸出條件下的銅回收率和酸消耗:1) 45% 固體,2) 1.8 pH 值(每天調整 pH 值以確保遊離酸可供浸出),3) 在 2,4,6,8,24,48 和 72 小時下對孕浸出溶液(“PLS”)進行採樣,4) 對 PLS 進行了銅、鐵、pH 值分析亞鐵(Fe++)和鐵鐵(Fe+++)。從每種浸出殘留物中提取50克樣本進行銅、鐵和SeqCu分析。

A 100-gram sample was separated (riffled out) from each of the 1-kilogram samples and pulverized for QEMSCAN analysis using the BMA (Bulk Mineral Analysis) to provide; 1) Modal Mineralogy and Abundance (including copper speciation), 2) Copper Deportment, and 3) QEMSCAN vs Assay Reconciliation.

從每個 1 千克的樣本中分離出一個 100 克的樣本,並使用 BMA(散裝礦物分析)進行粉碎處理,以進行 QEMSCAN 分析;1) 模態礦物學和豐度(包括銅形態),2) 銅分離,3) QEMSCAN 與分析對賬。
