What are the core issues?
The proposed Tamarack Mine poses significant risks to the Mille Lacs Band of Ojibwe's people, water, fish, and Manoomin (wild rice).
The proposed Tamarack Mine site is within miles of the homes of the Band’s community members and cultural sites like Rice Lake and Sandy Lake.
The environmental impacts of the proposed mine will add yet another stress to the natural environment, Manoomin (wild rice), medicinal plants, and cultural resources that are struggling to survive and adapt to the rapidly changing climate. The medicines used in the Band’s Midewin ceremonies will be damaged, which will prevent Band members from fully practicing their culture and beliefs.
CLEAN WATER DRIVES OUR FUTURE.
THIS IS OUR WATER. OUR FUTURE. OUR CHOICE.
We call on MinnesotaNS to HELP US prioritize clean water over nickel mining.
In addition, mining and industrial activity so close to the Band’s reservation and within the Band’s treaty-ceded territories and trust lands further exacerbates the forced colonization, oppression, and discrimination that indigenous communities have endured for centuries.
The proposed mine is located within the ceded territory of the Treaty of 1855.
Several reservations were established by our ancestors in that treaty, including the Mille Lacs Reservation and a reservation at Sandy Lake, and those reservations were so located because of their access to sacred lakes and waters that provided food and resources. Those same lakes still provide resources to our people today, and they must be protected.

Environmental Risks
Nickel mining presents a significant threat to the environment.
This proposed Tamarack nickel mine isn’t just a Mille Lacs Band concern — it’s a watershed moment for all Minnesotans.
The practice has a consistent track record of impairing water quality in water-rich environments, like the area surrounding the proposed Tamarack Mine site. In nickel mining, metals and material waste are taken from the ground and exposed to water. This can create sulfuric acid, which has the same chemical composition as battery acid and may result in acid mine drainage that would affect not only surface and groundwater supplies, but also aquatic life, plant life, cultural sites, and more.
Additionally, the proposed nickel mine poses a significant threat to Minnesota’s natural resources and watersheds. The watershed surrounding the proposed Tamarack Mine flows into the Mississippi River and St. Croix watersheds, which puts critical drinking water sources and habitats at risk as well.
Every glass of clean water drunk by a child in Minneapolis, every grain of Manoomin (wild rice) harvested from Sandy Lake, every walleye caught in Lake Mille Lacs, and every paddle dipped in the river’s flow depends on the choices we make today about projects like the Tamarack mine.

Alternatives to Nickel Mining
Talon Metals continues to cite the high-grade quality of nickel at the proposed Tamarack Nickel Mine site as a key reason for state regulators to approve the project.
Nickel is a core component in electric vehicle batteries. But other options exist to source the nickel needed in electric vehicle batteries, including metal recycling. Metal recycling is a viable option that has proven successful in Europe, Japan, and China.
In addition to recycling nickel, we’ve seen rapid changes in the formulation of electric vehicle batteries.
Manufacturers – like Tesla – are shifting away from cobalt and nickel in battery production due to the controversy, cost and limited supply associated with extracting these materials.
Lithium iron phosphate (LFP) batteries are 20% cheaper, last 2-3 times longer, are significantly less flammable and have a smaller environmental footprint than nickel-cobalt batteries.
We caution against a false sense of urgency to advance practices that cause long-term environmental risks.
Impacts of the Tamarack Mine Proposal
-
• The proposed Tamarack Mine site is located just 1.3 miles from Round Lake and the homes of tribal members, and in close proximity to cultural sites, including Rice Lake and Sandy Lake.
• 97% of nickel deposits are located within 35 miles of Native American Reservations.

• Most of these mineral reserves are not actually located on reservation or trust lands, which would provide tribes with more control over mining activities, but are located within ancestral lands, where tribes once lived and still have cultural resources, but now have limited control due to current day ownership by the federal or state government or private parties.

• Nickel mining has a consistent track record of impairing water quality in water-rich environments, like the area surrounding the proposed Tamarack Mine site.
• The type of pollution that comes from sulfide mining is particularly dangerous to wild rice. Among the substances released by copper-nickel sulfide mining are: mercury air emissions, sulfate discharges, copper, nickel, manganese, iron, aluminum, and arsenic, as well as solvents and processing wastes. Two discharges in particular are detrimental to the health of wild rice beds: Sulfate and Mercury.
