MINE ID # OR PROSPECTING ID #: ai-1477-377 INSPECTION DATE: ~/ism7 INSPECTORS INITIALS: -A11~1_ OBSERVATIONS This was a normal monitoring inspection conducted by Tony Waldron of DMG along with Joe Welte, Matt Welte, and Joe Gagliano representing Summit Brick. The site is located approximately 5 miles northwest of Penrose, Colorado. The pit is situated around a small mountain in a transisition zone from a large outwash fan formation up into more mountainous terrain. The affected area was properly delineated with visible markers and there was a mine identification sign posted at the entrance to the site. The clay deposits are layered in uplifted angles per the mountain folds. Mining is conducted by removing the topsoil and arty overburden which usually exposes the clay layers which are then removed and stockpiled for removal to the Pueblo brick plant on an as needed basis. The entire clay deposit will be mined, meaning the small mountain will be completely leveled upon completion of mining. One question the operator had was whether or not they could sell decorative rock that is separated out from the overburden and whether or not they could crush some of the overburden into smaller sizes to be sold as decorative rock. The answer is yes, however, the mining and reclamation plan will need to be revised via a technical revision to the application. This revision should include the additional mining activities that are planned, such as the location of product stockpiles, overburden stockpiles, etc. and also the impact or change that this might have on the approved reclamation plan, especiaAy with respect to the post-mining topography. One problem that was identified and will require follow-up is the infrequent use of explosives on the site. In accordance with Rule 6.5(4) of the Construction Materials Rules and Regulations of the Colorado Mined Land Reclamation Board; "At sites where blasting is part of the proposed mining or reclamation plan, the applicant shall demonstrate through appropriate blasting, vibration, geotechnical, and structural engineering analyses, that off-site areas will not be adversely affected by blasting". Since explosives are used, even if infrequently, the appropriate analyses will need to be incorporated into the permit application via a technical revision. The details of this submittal are included on page three of this report. No other problems were observed and [his concluded the inspection. I & E Contact Address NAME: ]oseoh C.
