Ann: A4 Dome Potential to Support T3 Expansion Strategy, page-20

Yeah I’m not sure on the exact figures but i’ve read it’s 4.2km strike length and only about 10m thick on average but it changes - cupric is private so hard to get info.

You’ve really got 2 options sub level stoping - carry the waste rock back down the decline after its been through the concentrator and use it (plus concrete) to fill the voids or mine in a certain pattern so that you never need to back fill voids. They’ve figured out a pattern of mining where they can safely extract without the need to backfill (cheaper). That’s about the extent of my knowledge. Bring on the T20 EM and drilling in Q4.
