The Yellowjacket Zone consists of orogenic gold mineralization confined along the distinctive Pine Creek Fault system and is located immediately above the significant historic “Discovery” gold rush placer deposits.The Yellowjacket occurrence includes individual, mineralized quartz veins, that are hosted within pre-existing structures, as well as zones of mineralized vein arrays. Listwanitic altered ultramafic rocks are consistently associated with the gold veins and vein arrays, with the gold most commonly hosted in gabbro, diabase, basalt and andesite (brittle, crackle fractured rocks) in fault contact with ultramafic rocks. Free gold mineralization occurs as scatted coarse native gold grains associated with minor pyrite, chromite and mariposite (Morton, J., 2022; Technical Report on the Atlin GoldFields Project: Sedar/Pacific Bay Minerals Inc.).Yellowjacket has a BC Ministry of Mines Small Mine Permit (75,000 tonnes per year) in place with the operation currently under care and maintenance.About Pacific Bay Minerals LimitedPacific Bay Minerals is a Canadian mineral exploration company engaged in the acquisition, exploration, and development of mining projects.
