The company says:

MONTREAL, QUEBEC--(Marketwired - April 25, 2014) - Golden Tag Resources Ltd. (the "Company") (TSX VENTURE:GOG) announces that at the request of regulatory authorities, Company Management confirms that it does not know of any reason for the increased volume in the Company's share trading.

I see that there are still 1.1 million shares bid vs. around 550,000 ask so there is still some demand. As you say, someone is unloading but, on the other hand, someone is loading. Maybe AUM is buying? Who knows?
