NZX Operations (“NZXO”) advises that the ISIN for Minerals Exploration Limited (“MEX”) will
change on NZX from AU0000219347 to AU0000439838, effective at market open Friday,12

Exchange (“ASX”) resulting from that name change. The ISIN change ensures alignment
between NZX and ASX.
To facilitate this ISIN change and allow outstanding settlement obligations to be completed:
•
A temporary instrument (“
MEXZ”
) will be created and will begin trading from market
open on Wednesday, 10 December.
•
The existing instrument (“
MEX”
) will be halted at close of business (COB) on Tuesday, 9
December.
•
At COB on Thursday, 11 December, MEXZ will be renamed to MEX, and the original
halted MEX instrument will be delisted. The temporary instrument ensures settlement
continuity during the ISIN transition.
•
From Friday, 12 December, trading will resume under the original ticker MEX with the
new ISIN.
