Ann: Macro Launches Mining Services & Acquires Manganese Assets, page-12

I don't get why you worry about the trading at the moment.
There is no manipulation happening. There literally is no interest at the moment.
10M on a trading day is about 0.2% of the shares on issue notwithstanding all the options that will likely be exercised on top.
The value of the trades are clearly so small that they are probably amateur daytraders or just small retailers shifting their money elsewhere.
Those small sales are just unsold lots from an original higher quantity sale. There is no need to sell 3 shares at 0.03 to keep the SP down because there are heaps more at the same price.
Macro are still an explorer and penny stock. Large institutions and large retailers do not touch these.

Read their Forward Looking Statements in their announcements.

Until they go into production or some amazing numbers comes out from a JORC the SP will hover around these prices with low volume.
A market cap of $100M is already about its potential. There is nothing more that will happen until the accurate numbers come out of Goldsworthy or the other smaller sites.
This is a classic put it in the bottom draw and come back in a few months to see if anything has happened.
Looking at daily trades will drive you nuts.

We should hopefully see a pay day but nothing is guaranteed. If it was then the SP would be much higher now based on all the positive announcements.
