Ann: $2.5m Placement to Accelerate Drilling at Equador Project, page-43

Not quite correct, SUM have hand sorted out the dark minerals from the pegmatites for assay which they are calling rock chip samples. I personally do not agree they are rock chip samples given the hand sorting or processing of the rocks. They are bias samples and only represent how good Sandro and his team are 'hand sorting' the 'rock chips'.
When you have a look at old mate next to that artisanal mine the dark minerals look confined to faults and joints in the rocks and occur as quite narrow veinlets. Very difficult to drill these styles of mineralisation. Otherwise good post and I agree with you.
