The Pilgrim Resource Pilgrim Hot Springs Nome

Pilgrim Research

Current research builds on efforts undertaken in the 1970s and 1980s

Thermal Imaging

Temperature map of geothermal aquifer from Geoprobe holes (20 to 40 meters)

Drilling Program

Cosmos, August 2008 What we know today Location of upflow zone (within ~30 meters) Depth to bedrock Good estimate of available heat (~20-40 MW th ) Indication of larger regional geothermal system

Cosmos, August 2008 Next/Current Steps Drill one 35 cm (14 inch) diameter hole that will allow us to extract fluid to ‘stress’ the resource and measure response to develop a more accurate reservoir model. Pump up to 7500 liters per minute (2000 GPM) (upper limit) for a period of 5-20 days, and discharge at surface.

What We Hope To Do Produce at least 2mW of geothermal energy from pilgrim hot springs Build a transmission line to Nome Deliver sustainable, affordable energy by end of 2014
