Re: P2012 -006 Clean -up and Spill Mitigation Report
Dear Mr. Cunningham:
RECEIVED
OCT 2 4 2012
Division of Reclamation,
Mining & Safoty
In your inspection report of 9/25/2012, Corrective Actions, related to the loss of containment of
drilling fluid, requires Gold Hill Minerals take the following actions:
"The Operator shall provide the Division with proof that the drilling fluid has been cleaned up
per the recommendations of the USFS by the corrective action date. In addition, the Operator
shall notify the Division in writing of the changes that will be made to the drilling operations to
prevent future losses of drilling fluids." The corrective actions due date is 10/24/2012
The drainage has been cleared of drilling fluid as of the date of this letter. We did not receive
correspondence from the USFS as to their clean -up recommendation. We did discuss the matter
with the USFS during a subsequent site visit and were told to proceed as was discussed during
the initial site visit with the USFS and DRMS representatives on September 6, 2012.
We are leaving the sump with the fabric dam in place to catch any residual outflow from the
Bueno Mine Waste dump. We will periodically check the sump for any further drain down and
clean up the material as necessary. We will remove the sump and clean up any additional
leakage after spring runoff in 2013. (As you know this is a very dry area and drainage. We do
not expect significant amounts of additional seepage. We are leaving the sump as a precaution
against any additional loss to the drainage.)
Attached are a series of photography which demonstrate the cleaned drainage. We have included
a representative number of photographs and may provide the full set if needed.
The drilling program was modified to eliminate or reduce the outflow from the waste dump
during drilling. We were not able to completely eliminate the discharge. The sump prevented
any additional loss to the drainage. However, we were able to reduce the amount of water used
from approximately 6,000 gallons per shift to less than approximately 1,000 gallons per day.
