TORONTO, March 13, 2025 (GLOBE NEWSWIRE) -- NexGold Mining Corp. (TSXV: NEXG; OTCQX: NXGCF) (“NexGold” or the “Company”) is pleased to announce certain potential positive outcomes as it works towards the completion of its Feasibility Study (the “FS”) for its 100%-owned Goliath Gold Complex (the “Project” or “GGC”) located in the Wabigoon Greenstone Belt in northwestern Ontario, which includes the Goliath (“Goliath”), Goldlund (“Goldlund”) and Miller (“Miller”) deposits. The FS is being prepared in accordance with National Instrument 43-101 – Standards for Disclosure for Mineral Projects (“NI 43–101”) and is anticipated to be completed in the second quarter of this year.

Kevin Bullock, President and CEO of NexGold, commented: “We are pleased by the potentially positive optimizations and progress of our Feasibility Study for the Goliath Gold Complex, which we expect to release in Q2. We have incorporated the learnings from engaging with our potentially impacted communities with the goal of protecting traditional pursuits. The optimizations contemplated demonstrate the hard work of the NexGold team and our commitment to responsible development and environmental stewardship throughout all phases of our projects, including exploration, development, operations, decommissioning and reclamation and I am very proud of what we have been able to accomplish. These optimizations we are working on may have the potential to reduce the initial and sustaining capital costs as compared to our PFS (defined below) through a reduction in the footprint for the Tailings Storage Facility (“TSF”) and the overall development footprint for the Project. Also, with these modifications, there is potential for the earlier closure of the TSF and Waste Rock Storage Facility, which can also have the impact of reducing overall operating and financial assurance requirements from Year 4 onwards.”

Project Optimization Highlights

Over the past several months, the NexGold team, in cooperation with our partners at Ausenco, WSP, SLR Consulting Canada Ltd., Minnow Environmental Inc., RockEng and SRK, have worked to optimize tailings management with the goal of realizing reductions in the Project footprint, as well as capital and operating costs and the potential for an overall improvement in operational efficiencies from our prior studies. This has resulted in projected improvements to the GGC design, including:

Environmental Protections

Integrating the commitments from the Goliath Environmental Assessment (EA) with discussions from community engagement activities, the Company has incorporated these factors into its mine design and planning with the goal of improving the sustainability of the Project. Enhancement to water management systems is also expected to result in the reduction and minimization of effluent discharges, with a commensurate reduction in the proposed Effluent Treatment Plant (“ETP”), while still being designed to meet Provincial Water Quality Objectives (“PWQO”) throughout the mine life. The reduction in the TSF surface area eliminates overprinting any waterways where fish are present; as such, a MDMER Schedule 2 amendment identified in the PFS shall potentially no longer be required to advance the Project development. Progressive reclamation opportunities are expected to be incorporated into the FS to assist in the preparation and submission of a detailed Mine Closure Plan. Optimization of the mine sequencing will also potentially allow for earlier closure and remediation of the TSF and Waste Rock Storage Area, with the goal to be able to segment/isolate potentially acid generating and non-acid generating wastes as soon as possible.
