The overall optimism spilled over Lithium Americas Corp.

(NYSE:LAC) announced the results of its earnings performance in the third quarter of the year, where it widened its net loss by 2,243 percent to $199.16 million from only $8.5 million in the same period last year, dragged by higher losses on financial instruments measured at fair value.
Operating expenses also jumped by 58 percent to $9.7 million from $6.15 million year-on-year, amid higher exploration expenditures.
Despite the dismal results, Lithium Americas Corp. (NYSE:LAC) remained upbeat about its business, saying that it was “full steam ahead on construction” for the Thacker Pass mine project.
