Tosca Mining is focused on exploration and development properties in North and South America. The Company announced today that it is now trading on the OTC market's highest tier, OTCQX.

OTCQX distinguishes the best companies traded over-the-counter (OTC) from more than 9,000 securities traded on the OTCBB and OTC Link that are not required to meet any financial standards or undergo a qualitative review.

Spencer Grimes, Merriman Capital Managing Director, said: "Tosca Mining's Red Hills copper and molybdenum property in Texas makes it natural for the Company to increase its exposure to U.S. investors. Joining OTCQX does exactly that, and we are excited to help them in this process."

"Tosca Mining is excited to be trading on OTCQX, which will allow us enhanced investor coverage, including specific U.S. coverage, which we previously did not have. With our Red Hills Copper/Moly property being located in Presidio County, Texas, and a work program just starting, joining OTCQX will allow U.S. investors much easier access to our Company. We thank Merriman Capital for their professional support and assistance through this process," commented Ron Shenton, President of Tosca Mining.
