Sovereign Lithium, Inc. announced it has renewed 31 claims, (4,960 acres), on the Big Smoky Valley (BSV) Lithium Project for another year on the basis of the results of a Gravity Survey completed on the project in July 2013. The Gravity Survey was the initial component of Sovereign Lithium's 2013 exploration program on the BSV property in and around Esmeralda County, Nevada. James Hasbrouck of Hasbrouck Geophysics handled the analysis of the Gravity Survey's data.

As reported in July 2013, the gravity model indicates the presence of a basin that extends over most of the claim block with depths exceeding 500 meters. The defined large catchment basin indicates a geologic structure that has a strong potential for the accumulation of lithium brine from several nearby sources. The defined gravity basin is comprised of two areas of increased bedrock depths separated by a small saddle indicating a large area favorable to the accumulation of lithium bearing brines.

The Company's decision to renew these Big Smoky Valley leases also took into consideration recent industry activity in the area. In particular, on October 28, 2013, Ultra Lithium Inc. (ULI) announced it had signed a non-binding Letter of Intent with CCG Mining Inc. in a joint venture to explore and develop ULI's South Big Smoky Valley property in Esmeralda County, Nevada.
