2025 GANJ 41 SketchUp Pro (rev. 04-2025) computer models of the New Jersey Zinc Co. Sterling and Franklin mines

Computer models of the New Jersey Zinc Company’s Sterling and Franklin mines were built and are being shared for the annual field conference. The Sterling model is the most complete and includes representative details for all mine levels and stoped sections. The Franklin model is only partly developed using a small subset of the level maps and stoped sections that capture it’s geospatial extent and structural form. The associated zip files hold the raster imagery upon which the models are based. Please see the GANJ 41 volume proceedings chapter 2 for more details. Users assume all responsibility for access and their use.
