How much of that gold is free milling?We’re at 12k feet, got another 4 weeks until the snow starts trying to fall- digging fast at this point, and preparing to make sure equipment is covered for the deluge about to come!

You guys still out there ?
I wish my problems we're with millin, I always found tryin to keep on decent ore was toughest thing I deal with..
I hear you there. We're driving drift towards a good 6' core intercept but it's fairly slow going. Lately we've been fighting with dewatering; lines and Victualic couplings are giving us fits. We're getting at it and have the fixed plant recommissioned. It's still a bit before we'll be fully settled into a routine.
Wish I had a place like that to work, heck I show up everyday work for free just to do it.
If you're having trouble with wet drill holes and bootlegs, you might want to try some liners. You can get a 2,000' roll of anti-static poly for about $60.
Small quantities, sure, but we'd rather have it out of our hair. The natural recharge rate is more than adequate for supplying water to the drills.
As long as the safety fuse cap is on the surface and just initiating the detcord, I don't see a problem with it. You can secure the underground face from people and it's easy to attach a new detonator after you wait an hour should it not go off. Are the NONELs really old and maybe not in the best condtion? Dynamite is usually pretty sensitive. Another possibility is that you got some rocks or stemming that fell in and blocked the path from the primer to some part of the column.
The nonels are fine. We only had trouble with the first shot on a few holes using PETN boosters to initiate ANFO. Those boosters have been used up.
Is that an Eimco 911B. What broke down on it.?
The beach hunting has seen lots of sanded in conditions over the past 2 weeks. Not many good targets...
Sure is! Some threads in the steering cylinder wore out causing the cylinder body and head to separate about 1/100". That blew the o-ring apart and dumped fluid, so I bored the damaged threads out and used a longer Grade 9 bolt with a keeper nut instead. Total cost was about $11 in parts, it just took a bit to find the correct bolts.
I worked for Tamrock from 1986 to 1992. In those years the company aquire Drilltech which made large DTH drills and then Eimco which I was the parts person for in Denver. Eimco still supported a fair amount of 12Bs and larger over shot muckers in those years. Later Sandvik bought every out and that's when I left the company and went to work for Brunner & Lay throughout most of the 90s covering COLO,.AZ, NM, UT & NEV. Those were very active years with small to large underground mines. In the last 23 years I've been with BTE which merged with Midwest rockdrills and F&H Mine Supply. I threw in my hat this month to retire, Though my old employer who owened BTE had a falling out with the Midwest bunch and has started a new company with ownership under his wife to avoid any agreeing terms with MW. He's wanting me to join in with that operation now. Who knows maybe I'll continue on. It's been a long road for me involved in the mining business which all began in 1977 where I started out as a miner when I was just 20 years old, hanging wire & bolts with a genuine GD-S83.
