RE: Surety Release No. 6 (SL-06)
Golden Eagle Mine, #C-18-013
Phase III Bond Release
Dear Mr. Thompson:
The Division of Minerals and Geology has completed an initial adequacy review of Surety
Release No. 6 (SL-06) for the Golden Eagle Mine. Please review our comments/questions and
respond as appropriate. Where we have specific comments or questions requiring a response
or indicating future consideration, I have highlighted those questions in bold text.
Issues identified during October 26, 2006 field inspection
Ground water well location 218 was inspected and requires abandonment and reclamation of
the well location. Information in the form of dated drill logs submitted under your cover letter of
UU''x December 12, 2007 indicates that this well was drilled in late March 1975 and is therefore a pre-
law structure and not subject to reclamation bonding. The Division is evaluating this
information and will make a determination regarding this well locati
1 ? on in the near future.
An area of limited and/or poor vegetation was noted above the area of the reclaimed portal.
Due to the known presence of methane in the overburden in and around the mine permit area,
the Division suggested testing of the soil profile for the presence of methane. The Division
received a report on October 18, 2007 from Peak Project Management (PPM). This report was
conducted and written by Arcadis based on a site visit on August 23, 2007 to the Golden Eagle
S mine. Twenty points over the stressed area of vegetation were surveyed for the presence of
methane in the soil profile. The report concludes that methane is not present in concentrations
that would affect vegetative growth. The Division will evaluate and discuss this issue in the
overall evaluation of the revegetation success achieved at the site and include comments
in our written findings.
A sinkhole was identified in Area C of Figure 2 of the bond release application materials. An
August 21, 2007 Division inspection confirmed and documented the repair of this feature.
Mine disturbance markers consisting of white PVC pipe were noted and are required to be
Vey removed prior to approval of the bond release, in addition to other mine signage. At this time,
markers and signs have not been removed and/or removal verified by the Division. If not done
