Offtake Study Validating The Flexibility Of Offsite-Processing Configuration For New Amalga Gold Project

VANCOUVER – Grande Portage Resources Ltd. reported on the 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.
Previously disclosed was 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.
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).
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 material as part of this investigation.
The global copper concentrate market remains chronically undersupplied. Copper smelters are therefore seeking to better utilize available capacity through processing materials other than traditional copper concentrates. Demand for alternative feedstocks such as the gold-bearing New Amalga material is expected to increase as there is little relief forecasted in the copper concentrate supply.
Ian Klassen, President and CEO, said, “The results of this study show that the New Amalga material is a very attractive feedstock for a wide variety of potential third-party processors located throughout the world. This demonstrates the flexibility of the project’s offsite-processing configuration and its resiliency against future geopolitical or tariff risk.”VANCOUVER – King Global Ventures Inc. reported on the recently completed 9,000-foot, eight-hole diamond drill program at the Silver Cord Project in Yavapai County, Arizona. The drill program consisted of holes SC-25-001, through to 007, designed to test induced polarization (IP) anomalies beneath the historic Silver Cord Mine and to transect the host Spud Mountain Formation, where geophysical and geochemical data indicated strong potential for volcanogenic massive sulfide (VMS)–related mineralization.
Drilling successfully intersected multiple polymetallic intervals and confirmed the presence of a polyphase Ag-Pb-Zn-Sb vein system hosted within the Spud Mountain stratigraphy. The program also provided important insight into the nature of the IP anomaly beneath Silver Cord.
Eight-hole, 9,000-ft drill program completed with multiple holes intersected high-grade silver–lead–zinc–antimony mineralization typical of a robust hydrothermal vein system.   
SC-25-004 intersected a high grade 9.0 ft interval of 619.6 grams (21.8 ounces) per tonne Silver, including 1.5 ft interval grading 1,390 (49 ounces) g/t Silver (48 oz/t), 2.2 g/t Gold with strong Lead, Zinc and Antimony support. SC-25-007 intersected a high-grade 1.0 ft interval of 625 g/t Ag, 1.0% Pb, and 1,175.0 g/t Antimony.  
The IP anomaly beneath the Silver Cord Mine is interpreted as intense siliceous alteration and anomalous copper consistent with intrusive-related hydrothermal activity. Results support a model for multiple mineralizing pulses and stacked structurally controlled mineralized zones. 
The results of the 2025 Silver Cord drill program indicate that the project hosts a polymetallic vein system within the Spud Mountain Formation, with geological features that may be consistent with VMS-related hydrothermal processes. Several drill holes, including SC-25-004 and SC-25-007, intersected intervals characterized by elevated silver, lead, zinc, and antimony, while SC-25-005 and SC-25-006 returned Zn-Pb-Cu–rich stringer-style mineralization. Collectively, these results support the conceptual interpretation that the Silver Cord structural corridor acted as a long-lived hydrothermal pathway capable of transporting and depositing metal-bearing fluids.
Robert Dzisiak, CEO, said, “The Silver Cord drill program has delivered very encouraging results at this early stage of exploration. Several holes have returned strong polymetallic intervals, and mineralization remains open in multiple directions. These results continue to build our confidence in the exploration potential of the Silver Cord corridor, and we look forward to advancing the next phase of drilling to better understand the geometry and continuity of the mineralized zones.”
