Subsequent Events [Abstract]
Subsequent Events	Solitario has evaluated events subsequent to December 31, 2019 to assess the need for potential recognition or disclosure in this report. Such events were evaluated through the date these financial statements were available to be issued. Based upon this evaluation, it was determined that no subsequent events occurred that require recognition or disclosure in the financial statements.

Tabular disclosure of significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, losses resulting from fire or flood, losses on receivables, significant realized and unrealized gains and losses that result from changes in quoted market prices of securities, declines in market prices of inventory, changes in authorized or issued debt (SEC), significant foreign exchange rate changes, substantial loans to insiders or affiliates, significant long-term investments, and substantial dividends not in the ordinary course of business.
