Roxgold buying is probably related to the recent management/board changes and the desire to build a position. It owns a high grade, narrow vein deposit in Burkina Faso called Yaramoko with about 600k oz Au (I+I) at grades of around 10-20 g/t. A lot of hype pre-resource on what the size of the deposit would be drove it to over $2 (now ~$0.75).

The idea of U/G mining in a developing country with no current U/G mines and a region with only a handful is a big red flag for me. That said it is rare to see such high grades in West Africa and may be a good take-out candidate for someone nearby like Semafo whose Mana mine is adjacent to Yaramoko.
