The Patagonia Area Resource Alliance recognizes that the health and economic prosperity of our community of Patagonia is tied deeply to the well-being of the Patagonia Mountains and Harshaw/Sonoita Creek waterways. They are the source of our drinking water, clean air and the biological wealth drives our local economy. The PARA mission is to stop new mining in the Patagonia Mountains.

News Release: Conservation Wins over Exploratory Drilling in Arizona’s Mountain Empire


8/25/2015 Regal Resources Announces Update on Status of its Sunnyside Project. In conjunction with the approval by the United States Forest Service of the Regal Resources operational plan for the Sunnyside Project in April 2015, the USFS imposed an annual seasonal drilling moratorium on the Sunnyside Project extending from March 1 to September 30 to ensure that the breeding season of certain species of wildlife is not disturbed.
Subsequent to the USFS approval of the Operational Plan, two environmental activist groups applied to the United States District Court for an order to set aside such approval. The Court has not yet provided its ruling on the matter. If the ruling is not issued before the expiry of the moratorium on September 30, 2015, there is a possibility that the activist groups will seek an injunction to prevent the Regal Resources from undertaking any drilling activities on the Sunnyside Project pending delivery of the Court’s decision. Read press release here.

Regal Resources History in Patagonia

In April 2011, Regal submitted a Plan of Operation to the Coronado National Forest for exploratory mineral drilling in Humboldt Canyon for their Sunnyside Project. The Sunnyside Project was delayed because of a lawsuit brought against the Forest Service regarding their approval of another mining exploration project in the Patagonia Mountains.

Patagonia Area Resource Alliance joined together with Defenders of Wildlife and Sky Island Alliance and in December 2011 went to court seeking a timeout on construction of Wildcat Silver’s Hardshell Project on the Coronado National Forest in southern Arizona. We challenged the U.S. Forest Service for approving exploratory mineral drilling without required studies of how it will impact endangered wildlife and the environment.  View the press release regarding the lawsuit.

On July 11, 2013 Sierra Vista District Ranger Mark Ruggiero re-opened the scoping period for the Sunnyside proposal. He did so “to ensure that public involvement is current and comprehensive.” We appreciate the additional opportunity to comment. At issue was the amount of time that has passed since the original public comment period and that there have been significant changes in the area since then. We had repeatedly advocated with the Forest Service District Ranger that a new public comment period should be opened.

What is a Plan of Operation and What’s a Scoping Notice?

Check out our NEPA Resources page here. NEPA is the National Environmental Policy Act and is the environmental review process by which all federal agencies must comply for federal actions that could have environmental effects.

Having your voice heard…

“The environmental review process under NEPA provides an opportunity for you to be involved in the Federal agency decisionmaking process. It will help you understand what the Federal agency is proposing, to offer your thoughts on alternative ways for the agency to accomplish what it is proposing, and to offer your comments on the agency’s analysis of the environmental effects of the proposed action and possible mitigation of potential harmful effects of such actions. NEPA requires Federal agencies to consider environmental effects that include, among others, impacts on social, cultural, and economic resources, as well as natural resources. Citizens often have valuable information about places and resources that they value and the potential environmental, social, and economic effects that proposed federal actions may have on those places and resources. NEPA’s requirements provide you the means to work with the agencies so they can take your information into account.” From the Citizens Guide to NEPA
