[{"type":"text","content":"VANCOUVER, BC / ACCESS Newswire / December 1, 2025 / Grande Portage Resources Ltd. (TSXV:GPG)(OTCQB:GPTRF)(FSE:GPB) ("Grande Portage" or the "Company") is pleased to announce an update regarding offtake studies for its New Amalga Gold property in Southeast Alaska. The current development concept for the project envisions a small-footprint underground mining operation with third-party offsite processing, eliminating the need for an onsite mill or tailings storage facility.","length":496,"tagName":"p"},{"type":"text","content":"The company's previous news release dated October 20, 2025 discussed the receipt of indicative offtake terms from a leading global concentrate trading firm. Material from the proposed New Amalga Gold Mine would undergo size reduction and sensor-based ore sorting and then be transported for sale with no chemical processing taking place on-site. The trading firm would purchase the material for resale to a variety of third-party processors including base metal smelters, custom concentrates facilities, roasting operations, and leach plants. Many of these facilities are located in the People's Republic of China.","length":622,"tagName":"p"},{"type":"text","content":"To validate offtake flexibility against any future geopolitical or tariff risk, the company commissioned a separate independent marketability study with H Okumura Consulting Ltd which examined opportunities for sale of New Amalga material to processing facilities outside of China. This study has shown favourable results: in addition to the high amount of payable gold content, a notable finding is that the New Amalga material is an attractive copper smelter feed due to its high silica content. This potentially enables its use as an alternative to the silica flux which many copper smelters must purchase as an additive for the metallurgical process (as necessary to remove iron from the copper-bearing material and ensure it separates into the slag).","length":755,"tagName":"p"},{"type":"text","content":"While the New Amalga material does not contain copper in meaningful concentrations, copper smelters have gold-recovery circuits and can process this type of gold-bearing material with very high recoveries enabling favourable gold payabilities. Multiple copper smelters outside of China have expressed interest in the New Amalga m...
