Trading volume activity has increased a little during the past few days, but at current price this does not represent big investments:

4 weeks ending Sept. 25th  :  9.13 million shares on TSX
5 weeks ending Oct.  30th  :   9.1 million
4 weeks  ending Nov. 27th :   8.28 million
Week ending Dec.  4th       :   4.48 million
Monday Dec 7th still in afternoon process  440K+

Potentially many reasons, but with the share price range-bound since May 2020, consistent with a current weekly RSI at 49.26 and a weekly MACD flat,  the business plan and financing strategies are critical, including the very interesting decision to be a purchaser of feed rather than a dedicated processing services provider to Glencore.  The daily MACD recently crossing the Red in the rising direction and with daily RSI at 55.35 there may be a slight technical indication of positioning for a price move upwards,

Peace,
Good Decision-making to All,
