Cautionary Note Regarding Production Decisions

The Company's decision to potentially place the mine into commercial production, expand a mine, make

other production related decisions or otherwise carry out mining and processing operations, is largely

based on internal non-public Company data and reports from previous operations. The Company is not

basing any production decisions on NI 43-101 compliant reserve estimates, preliminary economic

assessments or feasibility studies and, as a result, there is greater risk and uncertainty as to future

economic results from the Guitarra Mine Complex, including increased uncertainty of achieving any

particular level of recovery of minerals or the cost of such recovery, including increased risks associated

with developing a commercially mineable deposit, and a higher technical risk of failure than would be the

case if a feasibility study were completed and relied upon to make a production decision.
