You can definitely prove that in the drill hole you just drilled, there definitely is no present day ore. And you can say with increasing confidence in the last 30 barren holes ou drilled, that if there are no values of interest, you have ruled out the existence of a mine in that particular block of ground. What you cannot say with 100% confidence, is that there is absolutely no ore within a reasonable distance of your last drill hole. But sometimes in eyeballing the ground, and the general tenor of the sawdust you just drilled, you can begin to feel sure that the chances of finding mind boggling wealth are getting increasingly slimmer as each passing duster returns it no-lode. Let me tell you a story about Reuben Daigle, a prospector from Quebec who travelled in the Kirkland Lake-Timmins area, about 1908. Pull up a chair, turn off the porn channel and crack open a Kronenbourg. One for me, make that two. Reuben Daigle (pronounced Diegluh,) was no fool. Prospected all his life. Could tell gold at a glance from spitting distance if it were pinhead size. Carried his own blacksmith's forge in the bush. Moiled samples of a pound or perhaps even five, put them in a graphite crucible and melted the whole thing down as one big assay. The grinding moils they used were long iron bars, of maybe 20 lbs, driven into a deep metal pot. They didn't fool around. Poured the gold when the sample was yellow hot into a small iron cone. The gold pours first, falls right through the melt, so practically after you have poured out 3 ounces, you can throw the rest away. It has no gold. When it cools, sometimes you add lead to the assay, so it collects all the gold, sometimes silver, and sometimes you don't bother, as you want only the gold and you can see the button well enough. If you used lead you have two more steps, one with a bone ash plate called a cupel. Heat it up and stand back a ways, the lead goes into the cupel and the silver and gold stays on top. When the gold-silver comes out of the lead, it flashes at you.. winks. They call it the blic. Put that in nitric acid and the silver is gone. All the gold stays in the glass beaker. That is your assay. 1/10 of an ounce gold leaves 1.6 milligrams of gold per lb. A two lb sample at one tenth of an ounce per ton has a 3.2 milligram gold bead. That is big enough to pick up with tweezers and flip into the air and catch in your hand. About three times the size of a pin head. You can't miss it. Reuben would be looking for stuff 5-10 times that rich, and the bead would be 16 to 32 milligrams. That is a cube 1.18 mm on a side. Not inconsiderable and hard to miss. If you drop it in a pan yo hear a distinct plink. If he took 5 lb samples, the gold cube he ended up with is 1.6 mm on a side. When you saw it in the beaker it was squashed flat to about 1/10 of a mm, so its plan view was 6.4 mm on a side. Missing that would require high blindness and an abiding courage. What most prospectors did, is roast the sample after panning the sulphides from a 2-3 lbs sample. The gold would come out of the sulphides and make a streak around the pan. You can pan to .01 oz/ton gold. You pan a 3 lb. sample to a one ounce concentrate bringing the effective grade up 48 times. So a quarter ounce vein would look like a 16.0 oz/ton vein. A 0.25 ounce per ton sample makes a bright yellow streak halfway around the pan that you can see from ten feet away. If you have gold in the vein, it cannot hide from these methods. You find it and that is that. So Reuben goes into the Porcupine all a flutter from the stories of the greenstone in that belt. Greenstone lava is the home of gold, and every prospector from Roman times knows that. Green lava, quartz, iron and mica .. the gold is there... Moses talked about it I believe. He works hard as a man can work. Every quartz vein he sees he works on. He sees maybe ten a day. After a whole summer he set to write home. "I am leaving my forge in the bush at the last vein I worked. I have never seen an area more devoid and barren of gold than the Porcupine." (It did not yet have the name Timmins, that was to come later with Noah Timmins).. "Not a trace in a thousand veins. I am giving up. No sense sending anyone on my trail." He left the forge were it was, in the bush by a quartz vein. 50 feet from where they would find the Dome Mine discovery outcrop, the richest single quartz vein ever found on surface in North America. It had so much gold showing int that high barren Dome of quartz (you wanted to know where they got the name Dome didn't you?) that Dome Mines put 1 inch boiler plate on it and drill-pinned it to the rock to prevent it being looted. It is said that it looked like God had a giant candle of gold and had dripped it all along the outcrop. And it was 20 feet wide. In the drilling of that structure, occasionally the bit would plug up, or burn and have to be changed out. It came back coated solid gold, having mudded completely with the metal. Never give up. Never, never, never, never, never. If you do, just take a rest for five minutes and get back on the drill. The Dome is the next outcrop. Trust me. geocities.com
