Well, going from 600 to 800m means instead of a quarter m we are looking at 1/3 m oz within shallow depth.The offsetting faults do not detract from that figure at all because the areas affected are still mineralised just offset. It may mean the potential to go deeper than 90/100m may be limited. It really depends, if you go deeper and need a wider pit it may very well mean that the width of the pit will encapsulate all sections of mineralisation, with the east/west pit sides alternating between mineralised areas and waste areas according to the offset status.
It may also mean there will be way less infill drilling needed if Troy concentrates on one section for the first pit. More depth could be achieved ultimately with one large pit encapsulating the earlier smaller pits in offset positions.
Things I do not like are that it seems a very narrow grid will be necessary for infill drilling, that current production will be cashflow neutral or only slightly positive until mid of the year and that local geology is complex at OC and we will have to wait for diamond drilling before we can get a realistic picture of the mining grade achievable.
If Troy concentrates on a 200m section along strike for a 200x80mx130m drilling campaign on a 10mx10m grid (worst case) that would take 2 or 3 quarters. Troy still has 5 quarters left until ore from OC is needed.
While I am sure being open in all directions is a good thing and OC will be much larger ultimately, the really great potential could be with Goldstar and Gem Creek or Upper Itaki, but it seems 2019 will not be the year where a lot of drilling will happen there.
