Star Diamond Corp. shares fell precipitously on Wednesday after the company said its joint venture partner Rio Tinto Exploration Canada Inc. is considering a potential exit from their project in the province Saskatchewan.

At 9:55 a.m. ET, shares were trading 61% lower at C$0.11.

On Tuesday after markets closed, the company said that Rio Tinto exercised its voting power to close the Star-Orion South Diamond project mine site for the rest of the year, and that it wouldn't commit additional capital to the project in that time.

Star Diamond holds a 25% interest in certain Fort a la Corne mineral dispositions which includes the Star-Orion South Diamond project, while Rio Tinto Exploration Canada, a subsidiary of Rio Tinto PLC, owns the rest.

Star Diamond said that during their joint committee meeting, Rio Tinto said it intends to review its alternatives regarding the project, including a potential exit.
