Amendment No. 1 DQ1 PKAA 2026*0376

April 14, 2026

Thank you for attending the Pre-Bid Meeting. The following clarifications and amendments should be noted and incorporated into the bid documents:

1. Please note that the Project Summary in the Project Special Conditions has been modified to state that we will safeguard 9 mine sites, 4 shaft/vertical openings, and 5 adits/horizontal openings.

2. The following Conservation Measures have been added to the Scope of Work:

CONSERVATION MEASURES

The following measures will be implemented to reduce potential impacts to species and their habitat:

· Contractors will be restricted to traveling and working on existing roads or mine disturbance areas, where possible. This is a constant, since the purpose of all of our projects is to reclaim previously disturbed land.

· Contractor will power wash all equipment, including ATV’s and trailers, to remove noxious weed seeds. Equipment shall be sprayed prior to entering the work site and is subject to inspection by the Project Manager.

· As necessary, all disturbances will be revegetated with native plant species, reasonably free from noxious weed species.

· No perennial water bodies, marsh, wetland, riparian habitat, or streams discharging into water bodies will be impacted by equipment, fill, or contaminants of any kind.

· If indications of a protected species are observed (obvious use, nests, tracks, fur, and scat), the appropriate agency would be contacted to ensure that the site is not being used by any species listed in Table 1.

· In response to Brown Capped Rosy Finch breeding season, closure installations before September 1 at mine sites 2, 3, 4, and 9 will be surveyed by a biologist within 14 days prior to the closure to confirm there is no nesting activity at the site.

· If any nesting migratory birds of concern are discovered on site, a plan to avoid impacts would be crafted and implemented.

· The mine sites were evaluated for the presence of, or potential for, bat habitat. Bat grate, bat cupolas, bat slot gates, culvert with bat grate or installations employing exclusionary methods will be applied for mine closure features 2, 4, 5, 10, and 11.
