Sixty North Gold Updates Scheduled Development at Mon Gold Mine, NWT
Vancouver, British Columbia--(Newsfile Corp. - June 19, 2026) - Sixty North Gold Mining Ltd. (CSE: SXTY) (FSE: 2F40) (OTC Pink: SXNTF) (the "Company" or "Sixty North Gold") provides an update on its plan to commence gold production this year on its wholly-owned Mon Gold Mine, Yellowknife, NWT.
Sixty North Gold has been informed that the Mackenzie Valley Land and Water Board ("MVLWB") has requested all mine and mill developers without an approved Water Management Plan to collect additional baseline sampling prior to submitting that plan. This change in policy is apparently derived from concerns about how the environment has changed subsequent to the drought and wildfires across the Northwest Territories. This directive affects Sixty North Gold and will delay our planned start-up timeframe.
The Company and its consultants have provided baseline data extending back to the 1990's when sampling was conducted by government inspectors and previous operators. More recent samples have been collected since the issuance of the Company's licenses and permits, and most recently from 2020. This includes baseline sampling in 2024 after the wildfire season in 2023. Discussions are ongoing with the MVLWB and its Inspectors to determine how this policy change affects the Company's previously announced plans to commence gold production at the Mon Gold Mine. Currently, only limited activity is being permitted on site.
The Company has submitted twelve management plans and has received approval for six from the MVLWB. Since the Company's last update dated May 19th, the Mill Design and Construction Plan, Ore Stockpile Design and Management Plan, and Dry Stack Tailings Design and Construction Plans have been submitted. The Dry Stack Tailings ("DST") Management Plan can be submitted on MVLWB approval of the DST Design and Construction Plan, which has also been submitted. The Interim Closure and Reclamation Plan is being replaced by a revised Closure and Reclamation Plan.
Dave Webb, President & CEO reports "We had been operating under an Advanced Exploration Plan under a board directive dated October 24, 2022, but that is now no longer effective. All mining and milling equipment and necessary supplies are on the property and crews are mobilizing to the property to commence preparatory work pending additional MVLWB approvals. We will comment further as soon as we have clarity on how the above change will impact our start-up time line, but remain optimistic that this matter will be expediently and satisfactorily resolved."
