Ann: Au-Cu Exploration to Recommence at Wellington North, page-5

if I remember correctly, at Rose Hill, the previous MD only tested the good hole at depth and when he saw there was no porphyry below if he abandoned the idea to explore further so Adam correctly claims the mineralisation is open at strike.
If Adam can prove around 500m of strike then there is nice little resource there as AuEq of the original hole stands at around 0.85g/t.
And there is always the possibility that mineralisation to be open at depth at another point along one of the sides from the original hole. This could be similar to the lithocap porphyry deposits that have thin layer of mineralisation with big strike but at one point that mineralisation leads deep into the core.

See below what I mean... MAG hit decent mineralisation with the first hole but missed the mineralisation as the follow up hole was drilled below the zone and only returned very low grades. As Adam test along strike he may stumble on the channel that leads to the deeper porphyry.
