[Geysers] Puchuldiza

I found this online, regarding Puchuldiza, Chile. Note the last  paragraph. 
 Which perhaps can be translated as "Oh, well."

LOCATION 
The Puchuldiza geothermal concession is located in Region I (Tarapaca) of  
northern Chile. The geothermal prospect is located in a broad valley at 4300 
m  elevation in the Chilean Altiplano, to the south of the Volcán Isluga 
National  Park. The naturally-occurring hot springs and geyser field at 
Puchuldiza are a  popular tourist attraction. However, the main “geothermal” 
feature is actually  man-made: an old mining exploration well drilled in the 
late 1980s produces  flowing hot water which cools upon hitting the air and 
forms snow and ice. 
GEOTHERMAL EXPLORATION  
Puchuldiza is one of the best and most well-documented geothermal prospects 
 in South America. Puchuldiza has been the subject of two major geothermal  
exploration efforts: one in the early 1970s by CORFO, with New Zealander 
and  Japanese technical assistance, and a second in 2007-2008 by SERNAGEOMIN. 
These  studies produced an extensive set of geologic, geochemical, and 
geophysical  data, eight temperature gradient wells, and six intermediate depth 
slim  holes. 
A small 20 kW pilot power plant operated at the field in 1978, producing 
from  a shallow, low temperature hydrothermal aquifer. The known shallow h
ydrothermal  system has measured reservoir temperatures of about 160ºC, with 
geothermometry  temperature estimates of 240 to 275ºC for deeper parts of the 
system. This  probable deep reservoir has yet to be proven, but is likely to 
have the  potential to produce more than 75 MW of power, making Puchuldiza 
one of the  largest geothermal resources in Chile. 
In November 2008, GGE Chile (and its predecessor Geotermia del Pacífico)  
launched an extensive surface reconnaissance campaign which included mapping  
geologic features, collecting water and gas samples for geochemical 
analysis,  and conducting AMT geophysical surveys. 
In September 2009, GGE Chile was awarded two geothermal concessions at  
Puchuldiza, totaling 15,000 acres. GGE Chile continued the surface  
reconnaissance campaign at the Puchuldiza concession in early 2010, conducting  isotope 
geochemistry, structural geology analysis and detailed geophysical  
surveys.  
As a result of the GGE and MRP transaction in February 2013, Puchuldiza is  
now owned by MRP.
