Forrest have a look at MZNO options, heads have started heading up closing at 1.9c today and were only 1.2 a few days ago, options expire in December this year i think. From what I can tell the options MZNO haven't run yet and are lagging the heads, exercised at 2c in December from what I can recall. options aren't my thing but they're being talked about on the MZN thread a bit and I know you're always looking for good option plays so thought I'd post for you to have a look and research if it's something for you.
MZN heads are a great play with KDR hitting new highs again and again and MZN extending their land holdings around KDR, higher risk than KDR but so far the risk is quite rewarding and should continue moving up especially once further news comes.
