Ann: Stonewall Advances Theta Hill DG4 Evaluation, page-3

Trenching wasn't part of the original approach. However, they noted that there is a fair bit of shale and fragmentation in the shallows so the changes to approach make sense. Either way, looks like they are combining RC and DD drilling with trenching. Theta has the goods (especially trench C and D) and only 700m from the CIL plant. You could almost carry the ore in buckets down the hill to the plant. I read it as a good update and with more progress to come. Also some good narrow width grade hits.
