BOX 628 <br />Creede, CO 81130 <br />Telephone: (719) 658-0556 <br />(719) 658-0506 <br />Cell: (505) 603-5356 <br />Email: egolfn2@hotmail.com <br />RE: Bulldog Mine Project, Mineral County - Reclamation Permit # M-77-215-Request for <br />Technical Revision <br />Dear Mr. Dupler: <br />Please consider this letter a request for a Technical Revision, (Hard Rock Mining Rule Section <br />3.1.10 (6) ), weed control and management plan. Enclosed is the attendant filing application fee <br />($216.00). <br />Weed Control Plan: To control/eradicate Canada Thistle, spray Milestone (aminopyralid) at a rate <br />of 7 oz/acre with an agricultural surfactant at 0.25 % v/v. in the spring and fall (late bolting or <br />prebud growth stage) with mowing where practical July to mid August. (Taken from Colorado State <br />Extension publication "Weed Management for Small Acreages" by KG. Beck Revised 12108). For <br />other weeds, spot: spray in early summer with a broad leaf herbicide such as 2-4-D and Dicamba with <br />a surfactant. This can be enhanced with mowing where practical prior to seed production. For <br />parking areas and roads spray plants with RoundUp (Glyphosate) any time weather is favorable. <br />This regiment will be aggressively followed in 2011 and 2012 and then as needed thereafter. <br />Anyone handling these products will read and strictly adhere to all label warnings and instructions <br />for storage, mixing, application and be familiar with the Material Safety Data Sheet (MSDS) <br />information. <br />Monitoring Plan: In the spring of 2011 the Bulldog Mine properties will be thoroughly scouted <br />identifying colonies of Canada thistle and locating them with GPS and wire flags or wooden stakes. <br />Field notes will reflect a description of size, number of plants and condition of the area. Field notes <br />will also reflect observations of other weed species, general numbers and locations. The properties <br />should be scouted again in mid August with observations noted and compared to the spring <br />observations. This practice should be repeated in August of every year noting any changes from <br />year to year. Once colonies of Canada thistle have been eradicated flags can be removed noting the <br />removal. Any change to the weed management practices should also be recorded in the field notes <br />and included in annual site inspection reports.
