Scott Petsel <br /> Subject: FW: Co DRMS NOI <br /> Attachments: Metallic Minerals FS NOI Letter - 2019-08-30.docx <br /> From: Brown, Walter A-FS<walter.brown@usda.gov> <br /> Sent: October 25, 2019 11:50 AM <br /> To: Scott Petsel <Scott.Petsel @metallic-minerals.com> <br /> Subject: RE: Co DRMS NOI <br /> This summer and fall Metallic Minerals conducted mineral exploration activities in the La Plata Mountains on private <br /> and National Forest System (NFS) lands in La Plata and Montezuma Counties, Colorado. Activities included geologic <br /> mapping, soil sampling, and magnetic surveying with a drone piloted by an approved UAV company. The activities were <br /> described in an 8/30/2019 introductory letter, attached to this message for reference. <br /> For the activities conducted on NFS lands, the San Juan National Forest concluded that an NOI was not required because <br /> the following types of activities are excluded from the operator having to submit a Notice of Intent, per 36 CFR <br /> 228.4(a)(1): <br /> • Operations that are limited to use of vehicles on existing National Forest System (NFS) roads; <br /> • Prospecting and sampling activities such as taking small mineral samples,gold panning, metal detecting(for <br /> mineral deposits, not cultural artifacts), non-motorized hand sluicing, battery operated dry washers, and <br /> collecting mineral specimens using hand tools; <br /> • Marking and monumenting mining claims; <br /> • Underground operations which will not cause significant disturbance of surface resources; <br /> • Operations, which in their totality,will not cause surface disturbance which is substantially different than that <br /> caused by other users of the NFS who are not required to obtain FS authorizations; <br /> • Operations which will not involve the use of mechanized earthmoving equipment, such as bulldozers or <br /> backhoes, or the cutting of trees, unless those operations otherwise might cause a significant disturbance of <br /> surface resources. <br /> Please feel free to share this information as needed, and let me know if you have questions or need more information. <br /> Sincerely, <br /> Walt Brown <br /> Geologist <br /> Forest Service <br /> San Juan National Forest <br /> p: 970-385-1372 <br /> waiter.brown(aD,uscIa.gov <br /> 15 Burnett Court <br /> Durango, CO 81301 <br /> www.fs.fed.us <br /> Caring for the land and serving people <br /> 1 <br />
