About Core Silver Corp.

Core Silver is a Canadian mineral exploration company focused on the acquisition and development of mineral projects in British Columbia, Canada. The company currently holds a 100-per-cent ownership in the Blue property, which covers a land area of 114,074 hectares (approximately 1,140 square kilometres). The Blue property lies within the Atlin mining district, a gold mining camp located in the unceded territory of the Taku River Tlingit First Nation and the Carcross/Tagish First Nation. The Blue property hosts a major structural feature known as the Llewellyn fault zone (LFZ). This structure is approximately 140 kilometres in length and runs from the Tally-Ho shear zone in Yukon, south through the Blue property to the Alaskan Panhandle Juneau ice sheet in the United States. Core Silver believes that the south Atlin Lake area and the LFZ have been neglected since the last major exploration campaigns in the 1980s. The LFZ plays an important role in mineralization of near-surface metal occurrences across the Blue property. The past 50 years have seen substantial advancements in the understanding of porphyry, skarn and carbonate-replacement-type deposits both globally and in British Columbia's Golden Triangle. The company has leveraged this information at the Blue property to tailor an already proven exploration model and believes this could facilitate a major discovery. Core Silver is excited to become one of the Atlin mining district's premier explorers, where its team believes there are substantial opportunities for new discoveries and development in the area.
