TORONTO, June 1 (Reuters) - Asanko Gold Inc shares fell as much as 20 percent on Thursday, a day after hedge fund Muddy Waters said that it was shorting the company's stock, citing concerns about production at its mines in Ghana.
Asanko shares were down 17.8 percent at C$1.80 in early morning trading in Toronto, after falling as low as C$1.75 at the open.
They had tumbled 13 percent on Wednesday morning as news of Muddy Waters short position surfaced, prompting trading in the stock to be halted for the rest of the day.
Asanko Gold issued a statement late on Wednesday, saying it disputed claims from Muddy Waters. (Reporting by Solarina Ho; Editing by Jim Finkle)
