In the Monte Cristo Range, including the area of the Eastside project, volcanic and associated volcanic sedimentary rocks of Cenozoic ages overlie Paleozoic marine chert, shale, siliceous argillite, siltstone, fine-grained quartzite, and lesser limestone. The Cenozoic rocks include (1) Oligocene and Miocene ash flow tuffs (24 to 26.7 Ma); (2) andesite flows, tuffs, dacite flows, and intrusive rocks of the Blair Junction sequence (15.7 to 22.2 Ma); (3) fresh-water lake sediments of the McLeans unit; (4) Gilbert Andesite (15 Ma) and (5) a series of rhyolite domes, associated rhyolite tuffs, and basaltic lava flows (7.2 Ma). Of particular importance are the 7.2 Ma high-level rhyolite domes, plugs and related pyroclastic deposits which host most of the gold and silver resources at the Eastside project.

The Eastside Gold Project hosts a NI 43-101 Inferred Resources at the Original Zone located in the northern part of the property and remains open to the south, to the west and at depth.  Eastside also contains Historical Resources at the Castle Zone located at the southern boundary of the property.   Seven additional high priority targets have been identified and a Phase I drill program at Target 5 was initiated March 7, 2017.
