Looking at the chart, .004 was quite a bit longer ago than one year. Those levels were between a year and a half and two years ago. While I do agree that $EMXC had a rocky time over that span of time, no one can deny going from a bottom of .0004 level to here and holding these new values does say investor trust is being built back.
Like you pointed out, in that time period $EMXC did lose a lot of investor's trust. This company has come off this rough time, built back investor's trust, (so much so that there pps has sustained its new level of value), has dealt with a situation out of there control, (their TA being investigated by the SEC) and is now ready to continue their plan to build this company back up, to levels this company has never seen before.
I know this can be a lot to swallow for some, but everything done has checked out so far and the pps reflects it. $EMXC is headed upwards, the TA issue being now taken care of is just another way this company is taking care of business for its shareholders.
