U.S. Geothermal Inc.: El Ceibillo Project Receives License to Construct and 
Operate 25 Megawatt Project 
BOISE, IDAHO -- (Marketwired) -- 09/18/13 -- U.S. Geothermal Inc.,
(NYSE MKT:HTM)(TSX:GTH) a leading renewable energy company focused on
the development, production, and sale of electricity from geothermal
energy, announced today that the Guatemalan Ministry of the
Environment and Natural Resources ("MARN") has issued an
Environmental License for the construction and operation of the
planned, first phase, 25 megawatt power plant at the El Ceibillo
The El Ceibillo development project is an advanced stage, steam
geothermal prospect within a 24,710 acre (100sq km) energy rights
concession located 8.5 miles (14 km) from Guatemala City, the largest
city in Central America. 
Temperatures in excess of 500 degrees F (275 degrees C) have been
encountered during recent drilling at this project.  
The license is based on the Environmental Impact Assessment Study
that was submitted in December 2012, describing the initial design of
the 25 megawatt facility, and requires the submittal of final design
specifications for review by MARN prior to starting physical
construction of the plant. Additionally, the license requires
compliance with all legal and regulatory requirements under
Guatemalan law, submittal of an air quality monitoring plan, and that
final design comply with the strict guidelines for noise, dust and
hydrogen sulfide emissions. Prior to issuance of the license, an
environmental bond of $344,850 Quetzals (approximately US $45,000)
was posted with the Ministry of Environment and Natural Resources. 
"The issuance of this license is an important step in our development
plans for the El Ceibillo Project," said Dennis Gilles, CEO of US
Geothermal. "While we are still working on developing the geothermal
reservoir, having the environmental license in hand will allow us to
move the project forward within an efficient timeframe."
