To me it looks as if a lot of investors were reassured that Noront still has excellent prospects in the 'ROF' with the last news release. Selling pressure looks to have been somewhat removed.
However going by light trading after things settled, down post news, it appears investors are still waiting for both positive assays showing some 'nickel or pgms' and indication of a sizeable deposit.
Pain that share price drifted back down but it's on such low volume that it shouldn't be of much concern.
We'd all have liked more and faster even though we should know this exploration takes time both to drill and analyse as well assay.
