hi,
just MHO, i am a bit concerned with the M/C - currently at roughly 500 millions.
considering that both MTN and BMN have around 50,000t of estimated JORC with a much smaller M/C.
now considering AGS only own 25% of whatever there is in B4M, AGS needs at least 50,000 * 2 * 4 = 400,000t of JORCed resource to justify it's M/C.
