Grande Portage Initiates Preliminary Economic Assessment and Receives Gold Payability Terms of Up to 87%
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 (OTCQB:GPTRF) ha annunciato l'inizio di una Valutazione Economica Preliminare NI 43-101 (PEA) per il New Amalga Gold Project nel sud-est dell'Alaska.
Il progetto ospita una risorsa mineraria ad alto grado di 1,4 milioni di once indicate e 0,5 milioni di once stimate d'oro ed è suscettibile di espansione. L'azienda ha ricevuto condizioni indicative di off-take che mostrano pagabilità dell'oro del 72%–87% a seconda della qualità, con pagabilità tipiche attese del 80%–85% utilizzando la separazione del minerale basata su sensori. Le spese di trattamento e raffinazione sono indicate come un riferimento del rame TC più $95/tonnellata e $10 per oncia d'oro contenuta in raffinazione.
Una bozza iniziale della PEA è prevista per l'inizio–metà gennaio 2026 con la finalizzazione prevista per la metà-fine febbraio 2026. L'azienda prevede una miniera sotterranea di piccole dimensioni con lavorazione esterna da parte di terzi per evitare un mulino sul posto o una discarica di scorie.

Ian Klassen, Grande Portage President and CEO comments: "The excellent gold payabilities in this indicative term sheet attest to the marketability of the New Amalga ore as a highly desirable feedstock for third-party processing facilities. This validates our strategy for developing the deposit as a DSO direct-ship operation, which will greatly reduce capital costs by avoiding the need to construct a processing plant at the site, while de-risking the regulatory approval process by eliminating the requirement for a tailings storage facility. We look forward to defining further technical and economic details as part of our upcoming PEA."

Cautionary Statement Regarding Forward-Looking Information
This news release includes certain "forward-looking statements" under applicable Canadian securities legislation. Forward-looking statements include estimates and statements that describe the Company's future plans, objectives or goals, including words to the effect that the Company or management expects a stated condition or result to occur. Forward-looking statements may be identified by such terms as "believes", "anticipates", "expects", "estimates", "may", "could", "would", "will", or "plan". Since forward-looking statements are based on assumptions and address future events and conditions, by their very nature they involve inherent risks and uncertainties as described in the Company's filings with Canadian securities regulators. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. The Company disclaims any intention or obligation to update or revise any forward-looking information, whether as a result of new information, future events or otherwise, other than as required by law.
Please note that under National Instrument 43-101, the Company is required to disclose that it has not based any production decision on NI 43-101-compliant reserve estimates, preliminary economic assessments, or feasibility studies, and historically production decisions made without such reports have increased uncertainty and higher technical and economic risks of failure. These risks include, among others, areas that are analyzed in more detail in a feasibility study or preliminary economic assessment, such as the application of economic analysis to mineral resources, more detailed metallurgical and other specialized studies in areas such as mining and recovery methods, market analysis, and environmental, social, and community impacts. Any decision to place the New Amalga Mine into operation at levels intended by management, expand a mine, make other production-related decisions, or otherwise carry out mining and processing operations would be largely based on internal non-public Company data, and on reports based on exploration and mining work by the Company and by geologists and engineers engaged by the Company.
