"Capers or did you mean kippers? I have yet to see vg in a ARU core or did I miss the pic? 5 -8 gm./tonne not world class in my books, EXL pulling those grades and in Canada, meters from a world class producer."
E. Charters comes back with this:
"You need vaginal retinoplasty. I had to remove the glitter from my eye by picking it out with tweezers after looking at the ARU core. It's ALL VG. Nugget factor will be horrific. I mean beneficially so. They could double their grade on milling. Maybe more. That has to be tested. Even pulp and metallic assays won't tell you that. 5-8 grams per ton.. is not world class? What do you smoke? I need some. Please don't tell me ectasy, crack and Hoover dumpings does that to your brain. 8 grams is .24 OPT by the old system. And 120 feet wide they can block cave at 5000 tpd. Cost to mine max 7 dollars/Tonne , cost to mill about the same, all up. That kind of width could be immensely profitable underground at 1.8 grams per tonne. 3 grams would be gravy. Fort Knox in Alaska mines 0.5 grams gold at a rate of 50,000 TPD. And they make money. Go figure.
Anything over 6 million ounces is considered "world class". It has critical mass. When you are over 12 feet you are into bulk mining and if you have a mining engineering brain and metallurgy is good, anything over 3 grams is doable. And from the amount of VG displayed and reported you can bet this ore is coarsely free milling, and 85% comes out by gravity even.
World class mines ran/run at 0.15 ounces per ton. That is 5 grams. Underground -- at 35 dollar gold. Hemlo. Kerr Addison. Detour. Dome Mines. Campbell Red Lake when they went to 2500 tpd. The average grade of a Canadian gold mine is 0.15 ounces per ton. The average grade of the Timmins gold mines was 0.15 ounces per tonne. That is not the tons-average, but the mine average. Kirkland Lake was the high grade camp. It ran at 0.40 OPT average but its stopes were narrow, perhaps 5.5 feet wide on average. Most of the ore mined in Canada was about 4 to 6 feet wide. Occasionally averaging 6 feet as in the Lakeshore. But in Pickle Lake where they mined about 0.35 OPT they mined about 3.8 feet wide in much of their ore.
There are a few aspects to the ore that have to be worked out. True width. Metallurgy. True strike. Grade at depth. Western area below flat lying fault. Overburden/mining method. You don't have feasibility yet. Lots of drilling to come.
Let it ride."

Some bright guys from Cornwall figured out how to use pumps quite profitably underground a while back. There have been hundreds of successful mines built under lakes and rivers, and seas.
Yes, Let er RIDE, up it goes mate! |
