Bob Oswald <br />Re: Carnation Mine, Permit M-1977-416 <br />Response to Apri12003 Comments <br />Page 2 of 2 <br />full of barren waste rock from the immediate vicinity. The filled portal entrance will be graded to a <br />slope not steeper that 2 : 1 horizontal to vertical. <br />Future Waste Disposal: Much of the waste disposed in the surface dumps originated from mine <br />development work to access orebodies. Itt modern times when individual orebodies are reached, <br />considerably less waste rock is generated. In the case of the Carnation Mine and the associated <br />mines in the area, most mine waste is deposited in mined-out areas underground, as this involves <br />less haulage and reduces additional surface disturbance. <br />Ore Loadout Structure: No plans presently exist to replace the ore loadout structure, which was <br />removed in November 2002 due its failing and unstable condition. If ore is brought out through the <br />Carnation portal in the future, it will be stockpiled on the surface in the area of the existing surface <br />structures or on ground which has already been disturbed, but not yet reclaimed, within the Permit <br />area. <br />Powerline Ownership: The Operator has provided maps showing ownership of power lines in the <br />local area of the Sunday group of mines. These maps are on file for the Sunday Mine, Permit M- <br />1978-285 and the West Sunday Mine, Permit M-1981-021. In addition, the 1" = 100' site map <br />submitted with the Technical Revision Request shows the ownership of power lines within the <br />immediate vicinity of the Carnation Mine. <br />"Old" Carnation Portal: This portal was closed in November 2002 by the Operator. This closure <br />is considered permanent, although the portal could re-excavated if needed for future use. <br />Corrective Actions <br />The remaining Corrective Action of marking permit boundary comers in the field was completed in <br />early November 2003, following the site inspection by the Division of Minerals and Geology. <br />Formal notice of resolution of this Corrective Action has been provided by the Operator under <br />separate cover. <br />Following approval of the Technical Revision, the Operator will finalize the site reclamation map. <br />Sincerely, <br />~v~ <br />Terry V.
