Mr. Pollard added, "Assets like Tonopah West are rare, and there is an increased demand for silver-primary projects located in North America.  Trading on OTCQX will provide enhanced access to U.S.-based funds and retail investors, bolstering Blackrock's stock visibility. This represents a natural step forward in the growth and evolution for the Company."
