Objectives: This is an alternate site for SR-1. The objectives of Site SR-2 are:


1.Characterize the 260 hammer operating parameters; i.e., flow rates, pump pressures, weight on bits, etc.

2.Characterize the hammer-drill and bit-spudding capabilities without casing.

3.Test the entire HRRS system by drilling in 20+ m of 13-3/8" casing in a fractured hard rock environment with little or no overlying sediment of talus and with little or no slope.

4.Test the entire HRRS system by drilling in 20+ m of 13-3/8" casing in a sloped fractured hard rock environment with little or no overlying sediment or talus.

5.Test the entire HRRS system by drilling in 20+ m of 13-3/8" casing in a sloped fractured hard rock environment with overlying sediment or talus.



Drilling Program: Test different bit types before attempt to drill in casing with hammer-drill system


Logging and Downhole Operations: None planned


Nature of Rock Anticipated: Outcropping basalt
