This shaft was originally dug around 1902, they got about 70t of ore out averaging 55g per ton. We are only averaging about 15gpt , hopefully it gets better. The reef is a quartz vein 6-10" wide, basically vertical.
G'day ILikeGold, mate could I ask how your taking 'cuts' or advancing in your drive, wether your drill and blast or jackhammer or other....
How do you go with ventilation, I found that once I have gotten past 8-10 meters down a shaft my breathing alone whilst heavy digging was enough to start filling the small area with carbon dioxide, I remember this because after a couple of hours once a got a wicked headache, I raced off to a tool shop and purchased a small single phase vent fan that came with a 4meter Flexi vent bag, made life s##t loads more comfortable, are you at this stage mate or do you have a second shaft not far away and use natural flow,
All legitimate questions mate, not trying to be a smart ass or anything, but everyone dose things differently just wondering how you do it,
