If the higher grade zone is 300m wide, it would be at least 900m deep (from surface), assuming breath is also 300m with specific gravity 2.9 (3), then we have about 250MT at 0.4%Cu (based on BTDD004). I believe this is worth 15c. ($250M market cap). Plus we have the lower grade stuff on each side, potential higher grades deeper >700m (like the other recent porphyry discovery at BODA - part of Macquarie Arc which Bottletree, Steam Engine, Cockie Creek is all part of) and the main event yet be found (as per announcement).
Interesting week ahead - looking forward to a trading halt "major company making copper discovery identified". Good night time to dream first
