Project Number: 298-3

Two new dimension stone prospect sites have been located in Lake County.

Dimension stone prospect Site L-210 is a black anorthositic gabbro located in T61-R11-36-SWSE.

Site L-231 is a dark gray troctolitic anorthosite located inT61-11-16 NW1/4 NE1/4, NE1/4 NW1/4, SE1/4 NW1/4, SW1/4NE1/4. Both sites exhibit good quarry block potential.

Further mineral rights and land issues will need to be addressed prior to a State offering these sites for industrial mineral leases.
