Ann: Half Year Accounts to 31 December 2018, page-32

I do not think that plan will work. Troy so far has proven 800m of strike length at OC. Very very likely to be increased to 1000m and if they find a continuation to the SE maybe something like 1000-1400m.
The market is not putting much value on OC because high grade deposits have the tendency to be complex. So I think the diamond drill results enabling structural measurements and understanding the deposit are what will trigger a big market reaction someday.
Also there are targets at Gem Creek that could trigger an upside revaluation pretty quickly.

We will see, my preferred scenario would be for the SPP to give Troy what they need (4-5m to have some wiggle room and not 7.5), see the share price below 13 until September to get rid of the options and then trial mining late in the year and maybe more and longer mining at Smarts due to the redesigned pit. That would mean ore from OC will not be needed from second but from third or fourth quarter of calendar 2020.
