Proud sponsor of the annual El Tour de Tucson 

Rosemont intends to be a good neighbor, a good employer and a good corporate citizen in southern Arizona. We've got plans in place to be all three.

Native plants being salvaged on site at the Rosemont project 

During the 11+ years of permitting and interacting with the community, Rosemont has continued to listen to concerns and has responded by offering to implement many mitigation and conservation measures in addition to those typically required by the Forest Service. Through the permitting process, these voluntary measures have become part of the list of mitigation components required by the Forest Service. The successful completion of the permitting process will initiate Rosemont's various conservation plans.


Rosemont is committed to protecting and enhancing conservation and recreation in the region. The company will contribute up to $25 million to an endowment during operations that will remain at the end of operations and can be used to support a trust dedicated to conservation, recreation, cultural and environmental conservation projects, education and other environmental purposes. 

Wildlife Conservation 

  • To enhance understanding of large predators, including the jaguar and ocelot, Rosemont will provide $50,000 to the University of Arizona for camera studies in travel corridors. In addition, Rosemont will fund a 20-year camera study in a 200 km area around the Project. Total estimated costs are expected to exceed $8 million.   
  • Rosemont will plant approximately 38,000 Palmer agave plants on-site during reclamation. These native plants will enhance the food supply of lesser long-nosed bats.
  • Rosemont will provide $1.25 million to the Forest Service for Western Yellow-Billed Cuckoo and Southwestern Willow Flycatcher habitat enhancement and monitoring, along with surveying and conservation property management.
  • Rosemont will allot $3 million to the Forest Service to sponsor projects to manage and remove harmful non-native species. 
  • To support Rosemont’s efforts on all biology-related issues and for the implementation and oversight monitoring of all conservation measures, the company will provide funding to the Forest Service for a full-time Biologist position.
  • Habitat Conservation 

  • Rosemont will implement conservation measures on 4,500+ acres of private land, including the 1,580 acre Sonoita Creek Mitigation Project which will:
    • Re-establish waters of the United States by placing channelized portions of Sonoita Creek back into the floodplain, which mitigates for 40.4 acres of waters impacted by Rosemont;
    • Re-establish 25.3 acres of riparian habitat by eliminating agricultural use of lands; and
    • Release approximately 580 acre-feet of surface water per year into the channel at Sonoita Creek to return perennial flow into the system. 
  • Rosemont will provide $2 million to the Cienega Creek Watershed Conservation Fund to preserve and enhance aquatic and riparian ecosystems.
  • To establish the Smithsonian Institution sky brightness monitoring system at the Fred Lawrence Whipple Observatory on Mt. Hopkins, Rosemont will provide $218,000 to offset start-up costs. Rosemont will also provide an additional $100,000 per year for the life of the monitoring plan. 
  • Heritage and Recreation

  • Rosemont will fund two new trailheads, with parking areas, constructed by the Arizona Trail Association. Our commitment of $650,000 will also be used to relocate 10 miles of the trail away from the Rosemont site.
  • We will provide up to $800,000 to the Coronado National Forest to produce a plan and develop facilities and infrastructure for alternative off-highway vehicle trails. 
  • The construction of the Sycamore Connector Road will provide access across the ridgeline between the east and west sides of the Santa Rita Mountains.
  • Rosemont will maintain the working cattle ranch and integrate activities into its operations.

Community Giving

In 2018, Rosemont contributed over $200,000 to local organizations and charities. Rosemont’s community giving priorities are focussed on supporting STEEAM (science, technology, engineering, environment, agriculture and math) education, social services, job training and organizations that support military personnel and veterans. 

Rosemont has offered to provide $500,000 annually for 25 years (following the start of operations) to support community giving. This commitment has been included in the Final Mine Plan of Operations. In addition to supporting our community giving priorities, funds also support recreation, cultural and environmental-conservation projects. A committee of employees receives all requests for donations and evaluate them monthly.

Traffic on State Route 83

State Route 83 (SR 83) is a scenic state highway stretching from Interstate 10 (I-10) near Vail, AZ, south to Parker Canyon Lake. It is the primary corridor that connects the Arizona communities of Sonoita, Elgin, and Patagonia – and many rural households – to Tucson. 

Rosemont’s primary access road will intersect with SR 83 which will increase traffic volume when construction and operations begin. 

Project activities along SR 83 represent a segment of less than 10% of the entire roadway length and an actual visual impact of less than 5%. In operation, some of the buildings on site, the tailings area, part of the pit, and some of the site will be visible for about four to six minutes when driving by.

We will contribute to support traffic flow and road safety in a number of ways, including:

  • SR 83 will be upgraded at the Rosemont site entrance to meet regulatory standards for use and safety and to minimize the impact to traffic flow by constructing additional turn lanes and through-traffic lanes.
  • Rosemont will provide funding to the Arizona Department of Transportation for a 3-inch pavement overlay from the mine entrance to the junction at I-10, along with associated striping, raising of guardrails, re-signing and paving of three existing pullouts to safely accommodate school buses. 
  • Rosemont will implement a delivery schedule that will minimize truck traffic during peak travel hours on SR 83. 
  • Employees will be bussed to the site when production begins, reducing the number of single-vehicle users on the road. 

Native Americans and the Rosemont Site

Ce:wi Duag (the Santa Rita Mountains) and surrounding desert valleys have been home to Native American groups for thousands of years. We understand the long history and connections that Native Americans have with the Santa Rita Mountains. We intend to respect those connections. Rosemont is committed to complying with the National Historic Preservation Act through the following measures:

  • Rosemont will develop and implement a cultural sensitivity training program and archaeological monitor training program to protect cultural resources. Rosemont will ensure that employees and contractors engaged in ground-disturbing activities receive ongoing training in site protection measures.
  • Rosemont will provide opportunities to collect plants for traditional, medicinal and ceremonial uses. Rosemont will schedule a week-long visit when tribal representatives can visit the mine site prior to construction to collect plant specimens and to conduct blessing ceremonies.
  • Rosemont is committed to appropriate management of cultural resources prior to construction. A treatment plan has been developed through consultation with the State Historic Preservation Officer and tribal representatives. Initial ground-disturbing activities near recorded sites will be monitored by a professional archaeologist and a tribal representative for the presence of additional human remains or archaeological artifacts.
  • Where appropriate, Rosemont will incorporate culturally important plants in Rosemont’s reclamation seed mixture. Rosemont will also permit collection of plants on conservation lands to the extent allowable under conservation requirements.
  • Rosemont will create an exhibit at the Rosemont Public Visitor Center, located at the Rosemont site, that will describe the 7,000 years of occupation of the project area, the importance of Ce:wi Duag and the knowledge gained as a result of the data recovery conducted for the project. Concurrently, Rosemont will use the information developed for the exhibit to create public brochures that will be accessible on Rosemont and Forest Service websites.
