Mineral Properties

Mining Concessions

In Mexico, mineral concessions from the Mexican government can only be held by Mexican nationals or Mexican-incorporated companies. The concessions are valid for 50 years and are extendable provided the concessions are kept in good standing. For concessions to remain in good standing a semi-annual fee must be paid to the Mexican government and an annual report describing the work accomplished on the property must be filed. These concessions may be cancelled without penalty with prior notice to the Mexican government. MLS is the concession holder of a series of claims titles granted by the Mexican government.
