Skeena Gold + Silver is proposing to develop and operate the Eskay Creek Revitalization Project (the Project), an open pit gold and silver mine at the past producing Eskay Creek Mine site located in northwestern British Columbia. The Project is located within Tahltan Territory1 and Tsetsaut Skii km Lax Ha Territory1. The Eskay Creek Revitalization Project will be an example of responsible and collaborative development, providing jobs and tax revenue for local communities. The Project entered the environmental assessment process in July 2021, and a Definitive Feasibility Study was completed in November 2023. Skeena Gold + Silver submitted an application for an environmental assesesment certificate (EAC Application) was submitted in August 2024. Skeena is committed to inclusive dialogue and meaningful engagement regarding all aspects of the Project development.
B.C.’s Environmental Assessment Office invites you to share your feedback on the proposed Eskay Creek Revitalization project from August 26th to September 25th, 2025. To learn more and participate in the public comment period, visit: https://engage.eao.gov.bc.ca/EskayCreek-EA
The Virtual Open House offers visitors summaries on key chapters of the EAC Application, links to the latest company newsletters and an interactive 3-D map of the Project for users to explore.
The Eskay Creek Revitalization Project is focused on reopening the historical underground mine as a conventional truck and shovel open-pit operation that will produce a gold-silver concentrate on-site which will be transported off-site to third-party smelters. The Project will process up to 3.6 million tonnes of ore, producing an average of between 0.20 and 0.25 million ounces of gold and between 5.5 and 7.0 million ounces of silver annually. Silver is an essential component in many industries and is critical in the production of electronic devices. The project will utilize existing infrastructure from the former mine.
Eskay Creek is a historic mine site with significant existing infrastructure already in place, including a fully permitted Tailings Storage Facility (TSF), camps, offices, and all-weather access roads into site. Clean power will be accessed through the Coast Mountain Hydroelectric Facilities (Forrest Kerr, McLymont Creek and Volcano Creek run of the river), partly owned by the Tahltan Nation, or by accessing the main hydroelectric grid. The capital cost of the development is estimated to be C$713 million.
Skeena Gold + Silver is committed to the principles of United Nations Declaration of the Rights of Indigenous Peoples (UNDRIP) and working collaboratively with local Indigenous Nations and local communities. For more information, please see our 2023 ESG Report.
Following a request from the Tahltan Central Government, the Project was designated by the EAO as a reviewable project under British Columbia’s Environmental Assessment Act in July 2021. The Project is also a designated project under the federal Impact Assessment Act, and the Minister of Environment and Climate Change approved a request for substitution in November 2022. This means that the BC EAO is administering both the federal and provincial assessment processes.
In June 2022, the Tahltan Nation and Province of British Columbia signed the Declaration Act Consent Decision-Making Agreement for the Eskay Creek Revitalization Project, which is the first of its kind. This agreement establishes the requirement for Tahltan consent before the Project can proceed, and sets the associated
decision-making process.
The information Skeena Gold + Silver is required to include in its Application for an EAC Application for the Project is described in the Hybrid Application Information Requirements issued by BC EAO.
The EAC Application includes:
A syndicate directed by Tom MacKay explored and identified more than 30 mineral showings in the Iskut River region.
Tom MacKay’s original cabin is still existing on-site today!
Exploration drilling in 1988 led to the discovery of the 21A and 21B zones.

Skeena is particularly proud of the mentorship program, which was launched at the start of 2020. There have been six Tahltan individuals that have participated in the program, whose career projections range from engineering, business studies, to apprenticeship within the trades. One of the goals of the program is to develop the mentees' skills and understanding of the mining industry, as well as expose them to the entire sequence of mine development, including planning, permitting, engineering, construction, and operations. Overall, this program aims to increase Tahltan representation throughout all levels of the company and to provide mentees with the ability, experience and knowledge to support decision-making regarding the Project, Territory, and company.
Skeena Gold + Silver has worked closely with members of the Tahltan Central Government (TCG) to develop environmental and social design principles such that Skeena can act as good stewards on Tahltan Land. These principles are used to inform and guide the Project design as it develops through its initial Preliminary Economic Assessment (PEA) design to its closure.
Skeena has existing agreements in place with Tahltan Nation including Communications, Exploration and Opportunity Sharing Agreements.

What kind of mine is Skeena proposing?
The mine is proposed to be an open pit mine with on-site processing of the mined material by conventional milling and flotation to recover a gold-silver concentrate for provision to third party smelters. Tailings and potential acid generating (PAG) waste rock produced from this process would be placed in the existing Tailings Storage Facility, while non-acid generating (NAG) waste rock would be stored in a waste rock storage facility.
How long will the mine run?
The mine will be constructed over 1.5 years, produce and operate for approximately 12 years, and complete closure over a three-year period.
How many people will be employed at the minesite?
During the construction period, there will be approximately 700 employees at site, while during operations, we anticipate having approximately 500 people working at site.
What is the expected tax revenue for the Province of BC?
The expected tax revenue from Eskay Creek is C$1.1B (BC Mineral Tax C$570 M & Provincial Income Tax C$440M).
How do companies qualify for contracting opportunities?
Skeena has a prequalification process for contractors that are interested in working with us. Interested contractors fill out a Skeena prequalification form, which is sent back to our purchasing department to be reviewed internally for completeness. If a contractor is approved, they are added to our Approved Vendors List. If you are interested in becoming an approved contractor or have more questions, please send a request for a prequalification form to purchasing@skeenaresources.com.
How do local communities benefit from the proposed mine?
Skeena’s goal is to maximize supplies, employees and contract opportunities from local communities for the proposed mine.
Will the mine impact wildlife?
High winter snowpack limits wildlife habitat in the area. Summer wildlife observations have identified that black bears, grizzly bears, mountain goats, and small mammals such as martens, wolverines, voles and marmots use this area at certain times of the year. The historical wildlife database (beginning in 1993) is being complemented with updated studies to be able to manage and mitigate any potential impacts.
What Indigenous Nations are in the vicinity of the proposed mine?
The project is located within the Tahltan Territory1 and Tsetsaut Skii km Lax Ha Territory1.
Concentrate transported to port of Stewart via Highway 37 and 37A will pass through Nass and Nass Wildlife Areas (as defined in the Nisga’a Final Agreement) of the Nisga’a Nation and the territory of the Gitanyow Nation.
What agreements have been signed with Indigenous Nations?
Communications, Exploration and Opportunities agreements have been signed with Tahltan Nation.
What is being mined?
The mine will produce a gold and silver concentrate.
Where will the ore be transported and how?
The project will produce a gold-silver concentrate, which will be transported via covered trucks on Highway 37 and 37A to the Port of Stewart. From here, it will be shipped to smelters offshore.
What are the existing facilities at site that will be utilized?
The existing Tom Mackay tailings storage facility that was utilized during the former mining operations has capacity for additional tailings and waste rock. This will be utilized in the revitalized project.
The existing access route from Highway 37 into the mine site is currently being utilized to support Skeena’s advanced exploration work and it will continue to be utilized during the Project’s life.
Additionally, Skeena Gold + Silver has refurbished existing office buildings from the former operation for usage.
How will the mine tailings be stored?
Tailings will be placed via a pipeline into the existing Tom MacKay Storage Facility.
What happens to the waste rock at the mine?
Waste rock will be placed in several locations including in an external waste rock storage facility (WRSF); back into the North open pit and the existing Tom MacKay Storage Facility.
