Mexoro Minerals Ltd announces operations update at the Cieneguita Gold Project

Processing on a full time basis with all systems functioning with commercial reliability and availability

BROOMFIELD, CO, March 22 /PRNewswire-FirstCall/ - Mexoro Minerals Ltd (OTCBB:"MXOM") (the "Company") today announced that it has attained full commercial production operations at its Cieneguita gold mine and mill in Chihuahua, Mexico. Operations have been conducted and sustained fully around the clock, 7 days a week for over 30 days with minimal stoppages. These achievements have been made possible by the establishment of additional water supply systems and improvements in the reliability of the power transmission and delivery facilities. This now enables the Company to focus on optimizing recoveries and incrementally increasing throughput of ore to the mill.

All required permanent personnel to operate the mine and mill at their planned capacities have been hired and are on the job. This now assures the Company's ability to mine and process the required tonnages to operate the mill on a continuous 24/7 basis with a feed tonnage and grade as originally planned. With the improvements and the anticipated increases in process performance, the Company anticipates that its production rate of 35,000 gold equivalent ounces per year for the joint venture with the corresponding net cash flows will be reached. To date the mill has produced 1,200 tons of primary concentrates, of which 800 tons have been shipped to the nearby concentrator at Choix for regrinding and final flotation and sale under the Company's concentrate sales contract with Trafigura, Ltd. The Company anticipates that the first regrinding operations and the first sale of concentrates will occur by the end of March.

At the mine, ore production has proceeded as originally planned, and stripping has advanced more rapidly than planned. At the present time, stripping has exposed sufficient material to supply full-time feed to the mill for the next 6 months. Stripping is now ongoing in additional areas to allow for proper blending of mined material to maintain a constant 3 g/ton gold equivalent grade for the feed to the mill.

"We are delighted with the fast and efficient completion of the mill and the smooth operational start-up that has taken place at Cieneguita," said George Young, president of Mexoro. "The Cieneguita joint venture team, led by Minero Rio Tinto and our Chairman Mario Ayub, have demonstrated their value in bringing the mill completely on line in less than 6 months from the initiation of development activities. Our now proven capability to build and operate a mine, on its own, creates significant additional value for our shareholders as we continue to advance what I consider to be an exceptional exploration portfolio."
