Seriously doubt anyone here would be willing to give you advice as specific as you ask.

Personally I feel more secure having taken some NOT holdings off the table and put the money away. This is speculation and much like a high stakes card game when you decide to cash in some of the earnings and let the rest ride.

I'm convinced that there is less downside risk in some of the area players who haven't yet found an ore body. Noront has a lot of value already given to it by the marketplace and my feeling is they have high expectations to meet before new highs can be made. The bar isn't set quite so high for the other players and percentage wise they have more room to move higher.

If Noront is $4.30 then I'd  feel differently and did buy more Noront today only to resell for nice, but not as nice as it could be, profit.
