andy, you mean the options offer. i would think pretty good.
a $0.02 exercise option with a 4 year expiry date while the spot price is $0.015 should be worth well over $0.004 (prolly between $0.006 and $0.008 depending on the volitility you use). So that is a minimum of a 50% return as I see it.
where will the SP be in 4 years is the question. It could be many many times the current spot price.
