The Whistler project is located in the Yentna Mining District, approximately 150 km northwest of Anchorage, Alaska. The geology of the Whistler project is characterized by a thick succession of Cretaceous to early Tertiary volcano-sedimentary rocks intruded by plutonic rocks. More than 70,000 metres of diamond drilling has been completed on the 170 km2 property and porphyry-style gold-copper mineralization has been identified at three main deposits: Whistler, Raintree West, and Island Mountain. In addition to these deposits, other targets have been identified on the property for future exploration.

A technical report was completed in 2016 and included maiden resources on the Raintree West and the Island Mountain deposits. In January 2023, GoldMining released an updated Mineral Resource Estimate for the Whistler project that includes the Whistler, Raintree, and Island Mountain deposits. The Whistler project has Indicated Mineral Resources of 118.2 Mt grading 0.51 g/t gold, 2.19 g/t silver and 0.16% copper and Inferred Mineral Resources of 317.0 Mt grading 0.46 g/t gold, 1.58 g/t silver and 0.10% copper. Mineral Resource Estimates are based on “marginal cut-off NSR grades” of $10.50/tonne for open pit (which do not include mining costs) and $14.50 per tonne for underground bulk mining (includes processing and mining costs).
