MARYSVALE, Utah--(BUSINESS WIRE)--May 7, 2002

UNICO, Incorporated (Arizona) (OTCBB:UNCN) is pleased to report that the Deer Trail Mine, in Marysvale, Utah, was visited yesterday by approximately 25 distinguished geologists and professionals as part of the 2002 Rocky Mountain Section Annual Meeting of the Geological Society of America (GSA) held in Cedar City, Utah. A presentation of the geology of the area was given by Charles G. Cunningham, author and co-author of several USGS publications and detailed geological maps of the area, including several reports on the Marysvale District and the Deer Trail mine. Mr. Cunningham's presentation was followed by a report by UNICO's Chief Geologist, Dan Proctor, and a tour of the Deer Trail mine. Samples of different types of ores found in UNICO's Deer Trail and Bromide Basin gold mines were examined and taken by the group.

It was the general conclusion of the GSA group that the rich silver, gold, lead, copper and zinc manto deposits, currently being mined by UNICO, are the surface manifestations of a much larger feeder system that is theorized to lie beneath the Deer Trail Mountain. This system is believed to be the source of many of the rich gold/silver and alunite mines in the historic Marysvale District. Some members of the group commented that alunite is an excellent mineral for indicating larger copper/gold deposits, and the presence of high-grade alunite at the Deer Trail site correlates nicely with other deep system, copper/gold deposits such as El Indio in Chile, which were also capped by alunite. They further noted that the abundance and quality of the alunite at the Deer Trail deposit (some of the purest in the world) speaks to the possibility of hosting a large copper-porphyry system. The Utah area has seen several large economic copper/porphyry systems such as in the Tintic District and Kennecott's Bingham Canyon mine and the Ruth deposit near Ely, Nevada. UNICO plans to design a drill program to explore the depths of the Deer Trail system as a soon as it is financially feasible.

Mr. Cunningham explained that the Deer Trail mine is an underground mine developed in a halo of gold-bearing and base-and precious-metal manto deposits adjacent to the easternmost of two cupolas on a blind intrusion. He further elaborated that on the Deer Trail Mountain, highly kaolinitized rocks mark a radial fracture pattern. An annular ring of base-and precious-metal deposits surround these altered areas. Quartz veins containing gold, silver, and minor base-metals cut propylitized volcanic rocks in part of the ring, and the Deer Trail mine exploits base-metal mantos and associated precious-metal veins in the carbonate strata along the eastern side of the ring. Hidden igneous cupolas that may host porphyry-type disseminated copper and molybdenum deposits, and adjacent metal-bearing skarn deposits have been interpreted to underlie these altered areas.

UNICO Inc., a publicly traded Arizona Corporation, is listed on the OTC Bulletin Board, stock symbol UNCN. This natural resource company is focused on the production of gold, silver, lead and zinc concentrates from its Deer Trail Mine, Silver Bell Mine and Bromide Basin Mines. Its mill facility is located at the Deer Trail Mine in Marysvale, Utah. Management believes these polymetallic mines have the potential to become profitable and develop a world-class ore body.
