Modern-day mining in Ned — and what it means for Boulder’s watershed 

May 15, 2026

A gold mine near Nederland is attempting to reopen after numerous violations of Colorado’s Water Control Act. The mine’s owners also sought to expand the mine from 10 acres to 200.

The final hearing on that application was set for this month. But just a few days ago, the application was withdrawn amid a sale of the mine to another company, The Mountain Ear reported.

The mine sits just a few miles from Nederland, which means the Town is watching the outcome very closely. We interviewed Nederland’s Town Manager, Jonathan Cain, ahead of the planned May hearing, in collaboration with The Mountain-Ear’s Tyler Hickman.

Even though the mine’s reopening has been delayed, that doesn’t mean it will never reopen. Cain believes the new owners will reapply to restart operations there. If and when they do, Nederland will also be watching. So will we: We’ll keep you updated as this story develops.

For now, here’s our interview with Nederland’s Jonathan Cain.

Hey Boulder Valley Frequency Listeners. This is our Friday check-in. Today we have an interview with Netherlands town manager, Jonathan Kane. But real quick, I want to remind you that the Outside Days Festival is coming up in Denver, May 29th through 31st. It's an annual three-day celebration of outdoor culture, adventure films, and live music. This year, the headliners include My Morning Jacket, Deathcap for Cutie, and Cage the Elephant, along with many other awesome bands. We'll drop the link in our show notes. Also, if you caught our Wednesday show, we interviewed Bonnie Payne from Elephant Revival, who is having an album release party tomorrow night at the Fox Theater in Boulder. Have a great Friday, everybody.

In recent months, a historic gold mine near Netherland was attempting to reopen after numerous violations of Colorado's Water Control Act. The mine's owners also sought to expand the mine from 10 acres to 200. The final hearing on that application was set for this month. But just a few days ago, the application was withdrawn amid a sale of the mine to another company, as reported by the Mountaineer. The mine sits just a few miles from Netherland, which means the town is watching the outcome very closely. We interviewed Netherlands town manager, Jonathan Kane, ahead of the planned May hearing in collaboration with the Mountaineer's Tyler Hickman. Even though the mine's opening has been delayed, that doesn't mean it will never happen. Kane believes new owners will reapply to restart operations there. Even when they do, Netherland will be monitoring the situation closely as an official stakeholder to the process. We'll keep you updated as the story develops. For now, here's our interview with Netherlands Jonathan Kane. Mining. It probably conjures images of white-bearded men in denim overalls, wielding pickaxes and wearing bandanas and floppy, wide-brim hats. Or, if you're from Appalachia like me, maybe the lantern-topped helmet and soot-blackened faces of coal miners spring to mind. Both are somewhat accurate representations of mining from decades or even centuries past. Some of Colorado's first white inhabitants were drawn here in the mid-1800s by the lure of gold and silver, and them there are foothills. But mining isn't just a historic endeavor. Even today, there are people searching for precious metals all throughout Colorado, including Boulder County.

SPEAKER_02

The Crossmine, located outside Netherland, has been intermittently mined for gold, silver, zinc, lead, and copper since the eighteen seventies. Crossmine was shut down in 2021 after its current owners failed to file required pollutant reports. A subsequent investigation found excessive traces of copper and lead coming from the mine between December 2020 and August 2021. The state charged owners, Grand Island Resources, or GIR, with violating the Colorado Water Control Act and issued a cease and desist order.

SPEAKER_03

The order was lifted in January 2023. Two years later, GIR turned in a new application, asking the state for permission to expand its operation from ten acres to more than two hundred. What followed was a series of adequacy reviews that found hundreds of issues with the application, many of which are still unresolved. Come January of this year, GIR yet again made significant changes to their proposal, enough to force a public hearing to officially amend the application.

SPEAKER_02

While some of the problems may be complex, they said, quote, We're also talking about straightforward technical issues. After an already lengthy application process where GIR was given several extensions, the state denied their amendment request.

SPEAKER_03

Just a few miles downstream is the town of Netherland. Ned is an official stakeholder in GIR's application. The town sent a letter detailing its concerns to state regulators in early 2025, and they're still watching the process closely. I sat down with Jonathan to talk about the cross mine, the history of mining along the peak to peak, and what outcomes the town is hoping for. Probably a giant question to start with, but like what is Netherlands interest in this issue?

SPEAKER_00

You know, we're a regional hub here on the Peak to Peak region, which is kind of um the highway that runs through the mountains here between generally Ido Springs and Esse' Park. There's a community up here. And right above the town of the Netherlands, it's the cross mine in the caribou mining district, it's what is historically called. And it has um a watershed that runs down through it into town. And I think when you look back at Netherlands history, it's always it started essentially as a mining town back in the 1800s when gold was first discovered here in like 1859. And so that's been an important part of our history and culture and economy for a long time. Mining's gone through several booms and busts. And I think that right now it's kind of looking like folks are starting to become more interested in it again. And some of the older mines, like the cross mine, are reopening. And so one of the things that we're looking at is some of the impacts that it has on our community in terms of water and just in terms of traffic that comes through town and the different kinds of things that will happen as they start scaling up operations there.

SPEAKER_03

Um, and so Netherland is an official party to the application working its way through a state process to reopen this mine. Can you say a little bit more about what that means? What like rights and responsibilities does it give you? Just basically, what does it mean to be an official party? What can you actually do? What say do you have in the process?

SPEAKER_00

This is a quasi-judicial process that's happening at the state level. And it's happening with an entity in the state government that looks at the impacts of mining and what needs to happen to permit it. And so what they're trying to do right now is get a new kind of permit that takes into account some of the different impacts, environmental impacts that they have at the mine up there. And so recently they applied for a new permit to start operations and to expand those operations. And when that happened, if you're a party that is affected by those operations, you can submit comments to the state, and then you're considered a person who is, you know, a stakeholder in the process, essentially. And that's what we are here. Um, that gives us the right to comments when they do go to their final hearing, which is happening here in about a month, I think, is when it's scheduled. It allows us to just stay abreast of the project, which is also all public information. There's a portal online with all the documents and things like that. But it just gives us the ability to talk through some of the things that we're concerned about that might impact us as we move forward. And all quasi-judicial processes are decided on criteria. So it's not like we can say, we just don't like this thing. We we try to say these are the things that we're concerned about and how are they going to be addressed? And that's kind of what we did with our comments in the in the case.

SPEAKER_03

Can you give a high-level overview of what those concerns are currently?

SPEAKER_00

Yeah, I think for us, our letter um says really explicitly we're not against the operation happening there. You know, there's been historic mining there for 150 years almost. What we said is that we thought the application was incomplete. And there was a lot of things that we expect to see from an application like that, like mapping and water quality um control plans and um different kinds of things like that, different documents that show what the plan is for the operations. And we didn't weren't able to find them in the application. And part of that is it's just a very complicated process, and they have to, you know, get all the things together and do that. And so when we put our comments together, we have a sustainability advisory board here, and our board of trustees, our sustainability advisory board, myself and our sustainability coordinator really worked to think through what the impacts would be on the water that comes into town, you know, on the traffic and noise that comes through town, potential impacts on Barker Reservoir, which is the big reservoir here in Netterland, that is a big source of water both for the city of Boulder and for the town of Netterland. And just thinking through things like emergency procedures and how we might be notified if there was something that happened up there and all those kinds of things that towns generally care about in such applications.

SPEAKER_03

To your point of how complicated this is, definitely as a journalist, it's been tricky to parse out exactly what's been going on. What is your knowledge of mining operations? And do you have any like outside expertise that you're tapping? Is town staff handling this? Do you have like a staff member assigned to it? How are you following along with these really like industry-specific and like niche topics?

SPEAKER_00

It's one of the assets of the Netherlands community that we have a lot of people who are really skilled in earth sciences. Our sustainability coordinator just recently graduated with a geology degree from Mines. And then we have several people on our sustainability advisory board who work in this space. I've worked in this space for a while. My family has been in Colorado since 1860 and has a mining background. And I am not an expert, I'm an admin for sure. But I think we were able to come up with a group of folks that could really think through the different impacts we have. And then I think like part of it also is Netherlands deals with land use issues every day. And I think most towns do. And when we think through them and we think about criteria, I think it really those processes are designed so people can wrap their heads around them and engage in process. And I know sometimes it doesn't work like that for government, but that's what we're trained to do. And so we used our staff and our boards to really think through what is reasonable. You know, I think it comes back to the idea that we're not trying to be nimbys and not saying that nothing can happen. Just, hey, let's let's think through how this could be done in a sustainable and resilient way that's safe for the residents of Netherland and safe for the folks up in Caribou that live up there as well.

SPEAKER_03

Is there a particular outcome that Netherland is hoping for?

SPEAKER_00

I think for us, we know there's other processes that happens after this as well. So there's things that happen with the EPA, there's things that happen with Boulder County. Um, there may potentially be things with town, just depending on how traffic routes and things like that. And so I think for us, what we're we're advocating for is safety, first of all. We want to make sure, you know, for instance, if you know, the the mineral belt that this mine exists in is famous for being acidic. Gilpin County and Idaho Springs, I think, have thousands and thousands of mines that took advantage of it over the last hundred um plus years, thinking, you know, like all the mining that's happened there. And this is the same mineral belt. And it's acidic and it has some challenges with like rock fracturing and things like that. So the way that water moves through that rock is really critical for us. And so I think for us, what we're really focused on is this idea of safety, making sure that um uh we're mitigating potential problems as much as humanly possible and going through that process. So I think that that's what we're looking for. We want to participate in the process and voice our concerns in that way. And I think that that's really something you hear across all of the 400 plus stakeholders that are part of this case, is we're just looking for safety. There has been some times in the past where there have been some concerning incidents at this mine and related to the water and things like that. And I think we're just trying to say, hey, we understand what you're trying to do, but let's make sure that we follow best practices and keep people safe. We have a legacy in history of mining, and it's something that you can see anytime you go for a ski trip or just a hike in the mountains. It's very easy to see it. And it's important to us, like that culture and history is important to us. Netherland wasn't always where it is right now, it used to be up the hill, very close to where this mine was. It was a town called Caribou, and then it moved down here. One of the things that we are really aware of in Netherland is sometimes folks don't know where we are, but we are kind of a critical juncture between where the wilderness meets, you know, urban areas. The watershed for Boulder County is up here. We have Barker Reservoir, which is a hugely important piece of water, and a lot of water just moves through this place. And so I think when we think about how water moves through rock and the different challenges that can happen, I think it really becomes clear and evident that our practices here for in terms of how we treat water and how we think about water need to be really a part of our conversation every day, just for resiliency for people who are past us as well. And so I think, you know, while Netherlands a super small town, it's kind of the tip of the pyramid of where urban kind of process starts in this area.

SPEAKER_03

It kind of sounds like what you're saying is like, hey, your water quality is in our hands. So do you want to uh tell listeners like, hey, we we got this?

SPEAKER_00

We try. Our town, we've spent a lot of time and effort, and we have a really good water, wastewater team here. We treat water, we go above and beyond our permit levels of what we need to remove from the water, and we work really extensively with City of Boulder on that. When you're here, it's just so obvious about all the wilderness that's around Netherland. And we take it very seriously. That's why we have a sustainability advisory board. Our comprehensive plan, which is a really important planning document for the town, is built around this idea of resiliency and thinking about water and fire and the different impacts they have on places that are external to us. But I think that that's really the whole ethos of this place, and it's kind of cool. Water in Clear Creek used to be brown, even you know, when I was a kid, and it's not anymore, it's clear. And it's because these impacts of what these hubby meterals do and the you know, how to remove them and how to treat them, we know how to do it. There's a whole host of technologies and procedures and things like that that can do it. And I think that's the important thing here is when we engage in mining now, I think the it needs to just happen the right way. And I think if it happens the right way, there's always things that can happen, but that greatly increases the odds that it can be done appropriately and all that kind of thing.
