Our TNM Drill Down function highlights the highest gold assays of the previous week. Drill holes are ranked by gold grade x width, as recognized by our sister firm Mining Intelligence (www.miningintelligence.com).
Donlin Gold LLC, the equal partnership in Alaska of Barrick Gold (TSX: ABX; NYSE: GOLD) and NovaGold Sources (TSX: NG; NYSE: NG), had the top-rated assays of the previous week adopted by i-80 Gold (TSX: IAU; US-OTC: IAUCF) at Granite Creek in Nevada and Tudor Gold (TSXV: TUD) in British Columbia.
Drill gap DC22-2068 on the Donlin challenge in southwest Alaska reduce 42.3 metres grading 30.68 grams gold per tonne (beginning at 117.5 metres depth) for a grade x width of 1,297. It included a sub-interval of 23.16 metres grading 54.22 grams gold per tonne.
Greg Lang, NovaGold president and CEO, known as the opening “one of the vital intercepts when it comes to grade-thickness ever reported on the Donlin gold challenge.”
Donlin reported outcomes from about half of this yr’s 141-hole drill program of 42,331 metres. The ultimate assay outcomes are due in early 2023.
The Donlin challenge, one of many world’s largest and highest grade gold initiatives, goals to assemble a traditional open pit mine consisting of a number of pits for an estimated US$7.4 billion. It will extract 30 million oz. gold over the 27-year mine life with sustaining prices of US$1.7 billion. Confirmed and possible reserves are 504.8 million tonnes grading 2.09 grams gold per tonne for 33.8 million ounces.
The corporate is working in the direction of making ready an up to date feasibility research and a growth choice, it stated final month in its third-quarter outcomes. It reported a “strong treasury” of US$125 million in money and time period deposits.
Nevertheless, the challenge, positioned 450 km northwest of Anchorage, faces opposition from Indigenous peoples over considerations about potential mercury and cyanide air pollution of the Kuskokwim River. A state listening to assessment of unpolluted water permits granted to the challenge is anticipated to final six months, Donlin stated.
Second for the week was drilling within the Ogee zone at i-80 Gold’s Granite Creek challenge about 320 km northeast of Reno, NV.
Gap iGU22-47 reduce 17.8 metres grading 28.2 grams gold per tonne for a grade x width of 499. Gap iGU22-43B returned 7 metres of 10.7 grams gold.
“Drilling within the Ogee Zone continues to intercept spectacular high-grade mineralization over substantial widths,” senior geologist Tyler Hill stated in a information launch. “The Ogee and South Pacific zones stay open at depth, offering substantial upside.”
A preliminary financial evaluation launched final November envisioned output of 1.2 million oz. gold over a nine-year mine life at an all-in sustaining value of US$963.40 per oz.
Measured and indicated assets for the potential open-pit challenge stand at 20.5 million tonnes grading 1.94 grams gold per tonne for 1.3 million oz. of contained gold.
Finishing the highest three of the week is gap GS-22-158 at Tudor Gold’s Treaty Creek in northwestern B.C. It reduce 592.5 metres grading 0.73 gram gold per tonne for a grade x width of 433.
“This gap confirms the consistency of mineralization all through the porphyry system and that no boundary on the northern aspect of the system has been encountered,” Tudor stated in a information launch. “Future exploration will goal the northerly extension of this method.”
The challenge, 12 km east of the past-producing Eskay Creek gold mine, has measured and indicated assets of 815.7 million tonnes at 0.66 gram gold and three.6 grams silver per tonne and 0.06% copper for 17.3 million oz. contained gold and 93.4 million oz. contained silver. Tudor says it is among the largest gold discoveries anyplace within the final 30 years.
