15. GEOGRAPHIC AND SEGMENT INFORMATION

The Company currently operates in three reportable segments, which are uranium, lithium and graphite mining activities, including exploration, standby operations and restoration and reclamation activities. As a part of these activities, the Company also explores, evaluates and, if warranted, permits uranium, lithium and graphite properties. The Company’s long-term assets were $24.4 million and $25.8 million as of June 30, 2019 and December 31, 2018, respectively. 100% of the long-term assets are located in the United States. The Company reported no revenues during the six months ended June 30, 2019 and June 30, 2018.

The reportable segments are those operations whose operating results are reviewed by the Chief Executive Officer to make decisions about resources to be allocated to the segment and assess its performance provided those operations pass certain quantitative thresholds. Operations whose revenues, earnings or losses or assets exceed or are expected to exceed 10% of the total consolidated revenue, earnings or losses or assets are reportable segments. Information about current assets and liabilities of the segments has not been provided because the information is not used to assess performance.

The table below provides a breakdown of the long-term assets by reportable segments as of June 30, 2019 and December 31, 2018:
