Grande Portage (OTCQB:GPTRF) announced initiation of an NI 43-101 Preliminary Economic Assessment (PEA) for the New Amalga Gold Project in Southeast Alaska.
The project hosts a high-grade mineral resource of 1.4 million ounces indicated and 0.5 million ounces inferred gold and is open to expansion. The company received indicative offtake terms showing gold payability of 72%–87% depending on grade, with typical expected payabilities of 80%–85% using sensor-based ore sorting. Treatment and refining charges are quoted as copper benchmark TC plus $95/tonne and $10 per contained gold ounce refining charge.
An initial draft PEA is anticipated in early to mid-January 2026 with final completion targeted for mid-to-late February 2026. The company plans small-footprint underground mining with third-party offsite processing to avoid an onsite mill or tailings facility.
Grande Portage Resources (OTCQB:GPTRF) has announced significant progress in technical and permitting initiatives for its New Amalga Gold Project in Southeast Alaska. The company has secured a five-year Fish Habitat Permit from Alaska Department of Fish & Game and completed several key technical studies including an initial Geotechnical and Hydrogeological Review by SRK Consulting and an aerial LiDAR scan.
The company has contracted two independent ore offtake studies and retained Ensight LLC as its NEPA consultant. The project envisions a small-footprint underground mining operation without an ore processing plant, leveraging its strategic location near tidewater and existing paved highway for third-party processing.
A recent MOU between Alaska and the Federal Permitting Council could help streamline the project's permitting process through the FAST-41 program.
Grande Portage Resources (OTCQB:GPTRF) has submitted an easement application to the State of Alaska for its New Amalga Gold project. The proposal includes development of a 1.3-mile (2 km) gravel road and two equipment staging areas.
The planned road development will reduce helicopter shuttle distances for drilling equipment and supplies by over 60% compared to the current staging area in Juneau Mendenhall Valley. This initial segment represents approximately one-third of the total distance needed from Glacier Highway to the project site.
The company envisions future development of a small-footprint underground mining operation without on-site processing facilities, leveraging the project's proximity to existing infrastructure for third-party processing.
Grande Portage Resources (OTCQB:GPTRF) has submitted a Special Use Permit application to the US Forest Service for its New Amalga Gold project in Southeast Alaska. The permit covers installation of environmental monitoring infrastructure, including meteorological data collection stations, stream gauging sensors, and communication systems.
The company has completed fieldwork including fish-habitat stream identification and wetlands mapping. Notably, the project's design excludes on-site ore processing, instead planning for off-site third-party processing due to the site's proximity to tidewater and existing infrastructure. This approach aims to minimize environmental impact by eliminating the need for a concentrator, tailings facility, and permanent waste rock storage.
