The basics of the story are that Rio Tinto wants to do some sulfide mining on land that includes a place called Eagle Rock, which is religiously and culturally important to Michigan's Anishinaabe Indians as well as non-native locals in the area.
A group of Upper Peninsula residents came to Lansing and staged this rally--one they classified as an environmental justice effort-- to oppose the Eagle Mine project projected to occur on the Yellow Dog Plains in Marquette County.
They had a number of complaints that they aired, including that the plan would desecrate a sacred site, that it did not adhere to previously agreed-upon treaty rights, and that the community was not engaged in the decision making about this mining site.
What I found interesting was that the presentations on the capitol steps were largely inclusive; one tribal spokesperson noted that the treaty made many years ago between the Anishinaabe and the US government was an agreement made by both sides--and that non-native Michiganders should be as offended at the breaking of promises as many natives were.
Here is one of many websites organized by the community around the yellow dog plains; it journals their efforts to stop the mining project: https://yellowdogsummer.wordpress.com/
There's also a local watershed protection group that is involved in the campaign: https://www.yellowdogwatershed.org/blog/
And just one more, a broader UP protection group: https://www.savethewildup.org/
Rio Tinto does promise jobs and industry, and lays claim to the resources (copper and nickel) that they have identified there. Here's one document from the company:
By coincidence the project chair for this mining effort is named Jon Cherry.
Green Scales will keep an eye on this project-- look for video clips from the capitol rally soon!
