Unico Inc. Receives Final Approval to Begin Large-Scale Mining Operations at the Deer Trail Mine and Mill

San Diego, Calif., April 21, 2005 -- Unico Incorporated (Arizona) (OTCBB: UNCN) today announced that the State of Utah’s Division of Oil, Gas and Mining (DOGM) has granted its formal approval of the company’s Large-Scale Mining Operations and Reclamation Plan for the Deer Trail Mine in Marysvale, Utah. The approval gives the Deer Trail Mining Company, LLC, Unico’s wholly owned subsidiary, the ability to expand its existing small mining project to a large mining operation and execute its long-term plan at the Deer Trail Mine. Mining operations under the plan may include activities conducted on the surface of the land for exploration, development or extraction of a mineral deposit, including, but not limited to, surface mining and the surface effects of underground mining, on-site transportation, concentrating, milling, evaporation and other primary processing.

As part of its large-scale mining application, the company posted a $136,100 reclamation surety bond in the form of a Certificate of Deposit issued by Wells Fargo Bank. Ownership of the CD is retained by Unico as part of the reclamation contract. The reclamation surety covers the area of disturbance on both private and Forest Service land affected by mining operations at the Deer Trail Mine.

Mining will be done all underground with the exception of the processing of the dumps from the upper Deer Trail Mine area. The underground mining operations are to be conducted via the PTH tunnel, and ore will be brought to the surface from the PTH portal. Ores will be transported to the mill site, approximately .75 miles east of the Deer Trail Mine, where they will be crushed and processed. The final concentrates will be bagged and shipped to be custom smelted by outside sources.

Through its operations, all water will be recycled through the concentrating process, additional water coming from the freshwater makeup pond or decanted water from the surface of the tailings pond. Water from Cottonwood Creek will be used in the milling circuit.

The current area of disturbance filed by the company is 12.81 acres including ponds, dumps, mining and processing facilities. The company has the ability to increase this amount as the demands of the project dictate. The tailings are stored in a HDPE lined pond approved by the Division of Water Quality. The mine also has an approved Air Quality permit.

“Approval of this Large-Scale Mining Plan is a significant milestone and paves the way for expanding mining activities at the Deer Trail. We are now able to implement our strategic mining plan and increase the volume of activity on site. From this point forward, the company will be working diligently to facilitate a more effective method to process material and operate the mine than it ever has in the past. As evidenced with this endorsement by DOGM, management has a firm commitment to promote the overall expansion of the Deer Trail Project in Marysvale, Utah,” commented Mark A. Lopez, chief executive officer of Unico Inc.

“The ability to expand the size of its mining operations will highly complement many other activities at the Deer Trail Mine, including the Phase II diamond-core drilling program currently underway inside the PTH Tunnel. In less than a year, Unico has taken major steps in its investment to provide a framework and structure for the long-term growth and development of the Deer Trail Mining Company, LLC. It not only intends to develop the subsidiary into a revenue generating entity, but is determined to extract the value believed to exist on this property, which can then be passed on to Unico’s portfolio and its shareholders alike,” added Mr. Lopez.
