Ann: Exploration Update, page-27

They're no longer being quoted, so you can't buy on Commsec as of today

You can still exercise until WST 5pm 14/7, with a RMX price at 0.01 - buying options at 0.001 & executing at 0.008 puts you in at/lower than buying RMX on market.

Also the benefit of a free option for every three you exercise...I bought a bunch earlier in the week. I'll hold RMX at a cost of 0.009 & get a bonus bunch of options. Seemed like a good deal to me...
