Generation Mining - (Palladium)

Hey people. This week, after half a day of research into palladium develloper Generation Mining, I bought quite some shares as this stock to me seems hugely undervalued. Also the stock has not moved yet. Loads of insider buying the past few weeks between $0,35 and $0,48 so I thought buying around $0,44 was a good deal.

However, as I was buying at this level I noticed somebody was selling constantly to the bid at $0,44 for at least the 3 days that I was looking.

I was wondering, why would a large holder be dumping so many shares of low risk undervalued stock ?
