Greg Lewicki And Associates, PLLC <br />11541 Warrington Court Phone (303) 346 -5196 Fax: (303)- 346 -6934 <br />Parker, CO USA 80138 E -Mail: info a?lewicki.biz <br />April 17, 2015 <br />Mike Cunningham <br />Division of Reclamation, Mining and Safety <br />1313 Sherman Street Suite 200 <br />Denver, CO 80202 <br />RE: Extension for Review Hardrock NOI Application for Hock Hocking Mine P- 2014 -019 <br />Mike: <br />On behalf of Hock Hocking Mineral Company LLC, this is a request to allow additional time to <br />review the application cited above for the NOI at the Hock Hocking Mine in Park County, Colorado. <br />The reason for the extension is that the application information was submitted to CDPHE and they <br />have ruled that the NOI requires a full discharge permit, even though the exploration activity is very <br />brief. Since there is existing historic water then exits the mine, we have to be extremely careful since a <br />discharge permit could put the existing water out of compliance, creating a monumental treatment <br />problem. For this reason, we have submitted a PEL request to CDPHE and we have paid them to do <br />the analysis. <br />The PEL document issued by CDPHE will state what the permit limits would be if a permit was ever <br />issued. We will then compare these limits to actual water tests we have conducted on the portal <br />discharge and then decide if it is worth pursuing a discharge permit or if the project will be abandoned. <br />For this reason, we ask that the NOI be held in review until this work can be completed. Keep in mind <br />that we are doing all of this to ensure we comply with what the CDPHE ruled for the NOI. <br />Thanks. <br />Sincerely, <br />Greg Lewicki, P.
