At the time the enclosed COMOR forms were prepared, I reviewed a current title commitment. I also relied on several mineral research reports that have been prepared in relation to the Lake Springs Ranch property over the years (attached). The title commitment shows that mineral rights on the eastern portion of the Lake Springs Ranch property are owned by the Federal Government (BLM) and the mineral rights on the remainder of the property are privately owned. We would point out that the mineral rights citations in the current title commitment, which was updated on April 21, 2026, have not changed since 2004 when the original Assessment of Mineral Resource Potential report was prepared by Bio-Logic Environmental (See Exceptions 9 and 11 of Exhibit D, Biologic Report and the same exceptions in the current title commitment – Exhibit 4F). Based on paragraph 2, page 2 and paragraphs 3 and 4 on page 3 of the Bio-Logic Report, the mineral rights not reserved by the Federal Government have either not been severed, or the right to extract was never reserved. Therefore, all privately-held mineral rights have been retained as part of the estates owned by the Berkeley Family LLLP (PID #s: 218733300153 & 218733400107), and Plus Lazy K, LLC (PID #: 218733300154). Given that the Federal Government continues to own mineral rights on the Subject Properties, we have provided the address information for the local BLM office, as well as the addresses for the Berkeley Family, LLLP and Plus Lazy K, LLC Lake Springs Ranch PUD | Mineral Rights Research and Mailing Address 402 Park Drive ▪ Glenwood Springs ▪ Colorado ▪ 81601 ▪ P: 970.945.0832 ▪ E: tim@tgmalloy.com on the attached COMOR form and in the adjacent property/mineral rights mailing list included in the land use application to which this letter is a supporting exhibit. Separate COMOR forms have been provided for the Berkeley Family, LLLP and Plus Lazy K, LLC lands. The information included with this letter has been provided to the County in association with prior land use applications and has been reviewed by the County Attorney’s office and found to satisfy the requirements related to mineral ownership and public notice. Please contact me if you have any questions or require any additional information.

The property is known as Rivendell Farm, which includes approximately 169 acres of land that have been phased into conservation easements (CEs) between 2004 and 2009. Rare Earth reviewed An Assessment of Mineral Resource Potential report (dated December 28, 2004) prepared by BIO-Logic Environmental for the larger Rivendell Farm (see attached Figure 1), which, at the time, was known as the 438-acre Lake Springs Planned Unit Development. This property encompasses portions of Sections 32, 33 and 34, Township 6 South, Range 88 West (6th Principal Meridian) and Section 4, Township 7 South, Range 88 West (6th Principal Meridian). The 2004-2009 CEs are located in portions of the East ½ of Section 32 and West ½ of Section 33 (see Figure 2). Based upon maps & surveys provided by the Aspen Valley Land Trust and High Country Engineering, Inc., along with Bureau of Land Management (BLM) historical land status records, it appears that the Federal mineral estate was not accurately mapped in the 2004 mineral resource report. Figure 2 depicts the currently-understood boundary for Federal ownership of “all minerals,” which affects a portion of the 2006-2008 CEs. Otherwise, mineral rights at the remainder of the property appear to be privately held. Rare Earth reviewed geologic maps & aerial photographs for the property; State and Federal databases for mining & drilling information (obtained from the Colorado Oil & Gas Conservation Commission [COGCC] and the Colorado Division of Reclamation, Mining and Safety [DRMS]) for the site and surrounding area; and an updated BLM Mineral Management Status Map (Carbondale, 2008). No oil & gas fields are known to underlie the area and no recent, or planned, drilling activity or active oil & gas leases were identified in the COGCC or BLM databases for the property or adjoining lands. Additionally, no on-site or nearby State-permitted mining activities were identified. No mines, prospects, mineralized areas or patented (or unpatented) mining claims Exhibit C Mineral Assessment Report Update – Rivendell Farm Conservation Easement Property August 24, 2009 Page 2 of 2 were identified at the property or adjoining lands, and no veins or lodes are known to intersect the property. This letter serves as a current update to BIO-Logic Environmental’s 2004 mineral resource report, concluding that no significant changes have occurred at the property which would alter the original findings that the probability of surface mining occurring at the Rivendell Farm property is so remote as to be negligible.
