3) The operator's response to item no. 11 refers to information regarding water quality sampling

and M-1994-117. Firstly, any information referenced for the amendment under review must be

pursuant to Rule 1.10(2), the applicant shall clearly describe where, in the original application
and supporting documents, the information not included in the amendment application, but
necessary to render the amendment technically adequate, may be found. The operator did not
specify where in the permit file for M-1994-117 the water quality sampling and analytical data
for Left Hand Creek can be found. Please specify where this information can be found in the
permit file, or provide the information with your response.
CMC Response: A very thorough review of the Gold Hill Mill Permit No. 1994-117 shows that
water quality sampling and analytical data for Left Hand Creek can be found filed with the
DRMS on the following dates:
ITEC Environmental submitted water monitoring data on April 28, 1998 for the First Quarter of
1998.
Mount Royale Ventures submitted water monitoring data on March 6, 2009 for the Fourth
Quarter of 2005 through the third Quarter of 2008.
Gold Hill Mines, Inc. submitted water monitoring data on January 28, 2013 for the Third and
Fourth Quarters of 2012. On October 30, 2013 the DRMS approved Technical Revision No. 9,
which removed the requirement to sample Left Hand Creek from the water monitoring plan.
Exhibit C—Mining Plan (Rule 6.3.3):
4) The operator's response to item no. 15 describes only one 15 foot segment of the existing

be distributed along the access road below the excavation. Please confirm the areas to be
disturbed for removal of the existing pipeline, including areas where excavated material will be
