Grande applies for special-use permit at New Amalga

Executive Summary

• Grande Portage Resources submitted a U.S. Forest Service special‑use permit application for environmental infrastructure at the New Amalga gold project.
• The proposed infrastructure includes meteorological stations, stream‑gauging sensors, and communications/power systems to support long‑term environmental monitoring from pre‑construction through closure.
• Company reiterated its off‑site processing strategy, eliminating on‑site concentrator, tailings, and waste‑rock storage, thereby reducing footprint and capital costs.

Key Details

• Permit Application: Special‑use permit filed with the U.S. Forest Service to install:
• Environmental data collection station at prospective surface facilities (meteorological data for future Alaska Department of Conservation air‑quality and APDES permits).
• Additional meteorological monitoring equipment above potential underground workings.
• Stream‑gauging sensors to track seasonal river fluctuations and inform mine water treatment design that protects fish habitat.
• Satellite uplink communications and power infrastructure required for continuous operation of the monitoring system.
• Purpose: Infrastructure will support preliminary environmental studies, ongoing monitoring during construction, operations, and closure, and aid future permitting efforts.
• Recent Fieldwork (preceding two months):
• Identification of fish‑habitat streams and mapping of aquatic resources.
• Delineation of wetlands around prospective surface infrastructure.
• Data being incorporated into mine design to protect habitat, maintain wetland integrity, and minimize ecological footprint.
• Off‑Site Processing Strategy:
• No on‑site ore processing plant; gold will be processed by a third party near tidewater (≤ 4 mi from existing paved highway).
• Benefits cited: eliminates concentrator construction, tailings facility, permanent waste‑rock storage; no chemical reagents required; reduces power demand and CAPEX; simplifies permitting and closure.
• Qualified Person: Kyle Mehalek, PE, reviewed and approved the technical disclosure per NI 43‑101; independent of Grande Portage.
