Bank Financing Appraisals

 Financial Institutions need to know if the mining project will generate adequate cash flow to service the loan.  The value of the mineral property or operation as collateral must also be assessed to protect against default.  Both are functions of the market value of the mining property or operation.  AGI has appraised more than 220 mineral properties and mining operations for banking or other finance-related purposes.  Mr. Pincomb is a State Certified General Appraiser.
