Libby Exploration Project (Montanore)

Montana, United States · Underground

Under Development
SilverCopper
Overview
The Libby Exploration Project, formerly known as the Montanore Project, is operated by Hecla Mining Company through its wholly-owned subsidiary, Montanore Minerals Corporation. It is located approximately 23 miles south of Libby in Lincoln County, Montana. The project is a stratabound, sediment-hosted silver and copper deposit. The current focus of the project is on underground exploration and evaluation to gather data that will inform project engineering, environmental requirements, and overall feasibility.
Equipment
dewatering and rehabilitating about 7,000 feet of the existing Libby Adit (an underground tunnel), extending it by nearly a mile, and constructing additional lateral shafts for mineral exploration from underground drill stations
Expansion
In October 2025, the U.S. Forest Service issued a final decision approving Hecla's Plan of Operations for the Libby Exploration Project, allowing exploration and data collection to proceed. This exploration phase is expected to take 16 years. Following the exploration, the project would be closed and reclaimed over a three-year period, unless Hecla decides to pursue full-scale mining, which would require a new plan of operations and a public permitting process. As of early 2026, Hecla is in the process of obtaining a new water discharge permit from the Montana Department of Environmental Quality to support further exploration and development activities, with the permit expected in 2026.

Overview
The Rock Creek project, located approximately five miles northeast of Noxon, is a pre-development stage mine. Hecla Mining Company is not presently seeking permits for the mine's construction and is instead focused on its nearby Libby Exploration Project. The project does not have current federal authorisation to proceed. A 2021 court decision invalidated the U.S. Forest Service's approval for the mine's initial evaluation phase. The court ruled that the U.S. Forest Service and the U.S. Fish and Wildlife Service had violated the Endangered Species Act by not adequately considering the impacts of the full mine proposal on protected grizzly bears and bull trout. Should Hecla decide to seek a new permit in the future, new environmental analyses would be required. The project has faced long-standing legal challenges and opposition from environmental groups due to concerns about its potential impact on the Cabinet Mountains Wilderness, water quality, and endangered species.

The Phase 3 concentrator began feeding ore on 26 May 2024, months ahead of schedule. The completion of the Phase 3 expansion is expected to position Kamoa-Kakula as the world's fourth-largest copper mining complex. The 2023 Integrated Development Plan evaluates a staged increase in production capacity up to a total of 19.2 million tonnes per annum by 2030. The on-site smelter is expected to provide significant financial benefits by reducing logistics costs.

Overview
The Copper Wolf project is a large porphyry copper-molybdenum system located in a significant porphyry copper belt in Arizona. Previous mapping and drilling have confirmed porphyry-style mineralisation and alteration throughout much of the project area. Drilling in 2023 at the Bobcat prospect returned an intersection of 405 metres at 0.35% copper and 0.05% molybdenum. IGO Limited is now focused on a targeted drilling program planned for the first half of 2027, the results of which will inform the next steps for the project.
Expansion
IGO Limited acquired the remaining 49% of the Copper Wolf project from Buxton Resources for approximately A$6.15 million, moving to 100% ownership. This acquisition was announced in March 2026 and will terminate existing joint venture arrangements.
