Loans Payable [Abstract]
PPP Loan	On April 20, 2020, in response to significant market volatility and uncertainty, our general history of operating losses, and the resulting need for Solitario to conserve its financial resources, Solitario applied for and received a loan in the amount of $70,000 (the “PPP Loan”) pursuant to the Paycheck Protection Program under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) to help fund Company payroll, rent and utilities obligations. The PPP Loan has a two-year term and bears interest at a rate of 1.0% per annum. Monthly principal and interest payments are deferred for six months after the date of the loan. The PPP Loan may be prepaid at any time prior to maturity, under certain conditions, with no prepayment penalties. The PPP Loan promissory note contains events of default and other provisions customary for a loan of this type. The Paycheck Protection Program provides that the PPP Loan may be partially or wholly forgiven if the funds are used for certain qualifying expenses as described in the CARES Act. Solitario believes it used the proceeds from the PPP Loan for qualifying expenses and intends to apply for forgiveness of a portion of the PPP Loan in accordance with the terms of the CARES Act. However, Solitario cannot assure that such forgiveness of any portion of the PPP Loan will occur. As of September 30, 2020, Solitario has recorded $70,000 for the PPP Loan, including accrued interest through September 30, 2020 at 1% per annum, as a current liability. Solitario expects to repay its PPP Loan, less forgiveness, if any, within the next twelve months.
