Ferrocarillera is an epithermal precious metals property of approximately 7,000 hectares with good road access and year round working conditions.

Apex Silver may accelerate the retirement of its work requirements. After Apex Silver has earned a 55% vested interest in the property, the companies will form a joint venture for further exploration and development of the property. Apex Silver has the right to earn an additional 10% interest by spending a cumulative amount of $6,400,000 prior to the seventh anniversary of the agreement, and by making annual payments to Marifil of $75,000 until commencement of commercial production.

At Marifil's written request Apex Silver also has the right, but not the obligation, to earn an additional 5% (bringing its total to 70%) by funding Marifil's share of costs through to production.
