Toledo - Cashflow from the world's 3rd largest Nickel Resource

I must admit I found the days trading of TMC very interesting.There was virtually no interest until 1610hrs then 76000 shares were purchased up to the close.The two trades I found curious were the 1000 sell at £1.235 well over the bid price of £1.20 at the transaction time and the T trade of 25000.
With no news expected until the new year I thought it was a strange time to take out a T trade.I also could not work out why the bid price was dropped to £1.20 making a 10p spread.
I would be very interested in peoples comments on the above.
