Income Tax Disclosure [Abstract]
Income Taxes	7. Income Taxes Solitario accounts for income taxes in accordance with ASC 740. Under ASC 740, income taxes are provided for the tax effects of transactions reported in the financial statements and consist of taxes currently due plus deferred taxes related to certain income and expenses recognized in different periods for financial and income tax reporting purposes. Deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Deferred taxes are also recognized for operating losses and tax credits that are available to offset future taxable income and income taxes, respectively. A valuation allowance is provided if it is more likely than not that some portion or all of the deferred tax assets will not be realized. At June 30, 2017 and December 31, 2016, Solitario has recorded no net deferred tax assets. A valuation allowance, which fully offsets the net deferred tax assets, has been recorded because it is more likely than not that the Company will not realize some portion or all of its deferred tax assets. The Company continually assesses both positive and negative evidence to determine whether it is more likely than not that the deferred tax assets can be realized prior to their expiration. During the three and six months ended June 30, 2017, Solitario recorded deferred tax benefits of $89,000 in the statement of operations and recorded a deferred tax expense of the same amount to other comprehensive income related to unrealized gains on marketable equity securities. During the three and six months ended June 30, 2016, Solitario recorded deferred tax benefits of $175,000 and $237,000, respectively, in the statement of operations and recorded a deferred tax expense of the same amount to other comprehensive income related to unrealized gains on marketable equity securities.
