Summary:
Deposit Type
The Dublin Gulch intrusion is part of the mid-Cretaceous Tombstone Intrusive Suite of Alaska-Yukon granitoids, and the Eagle Zone belongs to the RIRGS class (Reduced Intrusion-Related Gold Systems) of mineral deposits. Gold mineralization in the Dublin Gulch intrusion shows strong similarities to the Fort Knox deposit in Alaska, including the presence of sheeted quartz veins and elevated levels of bismuth, arsenic, tellurium, and tungsten. The veins in the Eagle Zone consist of early quartz-scheelite with varied occurrences of pyrrhotite, pyrite and arsenopyrite, and are associated with K-feldspar and minor albite alteration envelopes. These are overprinted by sericite-carbonate and occasional chlorite alteration. The metasediments marginal to the intrusion are mineralized as well, but the bulk of the gold is hosted within the intrusive. The Dublin Gulch Stock is an elongate body trending 070°, with surface dimensions of approximately 6 x 2 km. Exploration for additional gold deposits is ongoing with significant potential for further discoveries.
The Dublin Gulch intrusion is composed of mainly biotite hornblende granodiorite. Minor phases of diorite and granite occur within the intrusion. The overall low sulphide content of the rock, commonly less than 0.5%, and the presence of carbonate (Calcite 1 to 4%) make the rock non-acid generating.

Summary:
The Eagle Gold Mine comprises the Eagle and Olive deposits which are planned to be extracted by traditional open pit shovel and truck mining methods. The mining equipment fleet is owner-operated with its own labour force. Mining activities began in Q2 2019 and have mined a total (ore and waste) of 66.9 M t up to 31 December 2022. Mining to date has all been in the Eagle pit. The first, initial phase of the Eagle pit was completed in early Q1 2022. Current mining activities are ongoing in Phase 2 and 3 of Eagle pit.
Description of Mining Method
The LOM scenario involves an average mining rate of 24.7 Mt/annum, with a targeted processing throughput of up to 11.5 Mt/annum. The mining strategy will include stockpiling of up to 17 Mt of lowgrade ore (incremental cut-off grade) to be reclaimed and processed in the final years of operation. Mining of the Olive pit will begin in the final years of the Eagle pit as the benches become too small to sustain targeted throughputs.
Ore and waste rock are mined in 10 m benches with final walls being double benched. Conventional drill and blast techniques are utilized, including wall control blasting.
The current LOM plan forecasts a total of 245 Mt to be mined over a period of 10 years. Processing of ore to the heap leach facilities is forecasted to total 124 Mt over a period of just over 11 years, with the final year and half primarily being from the rehandling of low-grade stockpiles.
