SPOKANE, WA--(MARKET WIRE)--Jun 30, 2008 -- Goldrich Mining Company (OTC BB:LITS.OB - News) ($0.38) (hereafter "Goldrich") reports initial results of gold analyses for eight of ten drill holes scheduled at the Marisol bulk-tonnage gold prospect in northern Sonora, Mexico. The diamond-core drill holes are part of an effort by the Company to evaluate the grade and continuity of mineralization near a series of old underground workings.

The table below presents the gold values realized from the current drilling program.

Eight drill holes have been completed to date testing 330 meters (1,080 feet) of strike length along the Marisol structure. The holes were drilled at angles varying from -45° to -90° to assist in determining the dip and potential convergence of two principal mineralized structures.

The upper mineralized zone, which is hosted by calcareous siltstone, was encountered in all but one drill hole (hole MAR-7 was lost before attaining the appropriate depth). The upper mineralized structure varies from 3.0 meters (9.84 feet) reporting 0.433 g/t gold (hole MAR-8), to 11.05 meters (36.25 feet) of 1.628 g/t gold (hole MAR-3), with a weighted average thickness of 6.0 meters (19.7 feet), having a grade of 1.60 g/t gold (0.0514 oz./ton).

The lower mineralized structure is hosted by a medium-grained quartz-feldspar arenite, or sandstone, and was encountered near the bottom of drill holes MAR-1, MAR-5, MAR-6 and MAR-8, which returned values and intervals as reported above. Each of these four drill holes reached the ultimate target depth necessary to penetrate a volcanic rock sequence that lies below the deeper mineralized structure.

Two additional drill holes are in progress in the vicinity of the La Jarra workings, which are situated approximately 1.7 kilometers (one mile) southwest of the Marisol workings. The La Jarra mineralization is hosted by quartz arenite, which coincides with significant gold-silver soil geochemical anomalies. Results for these drill holes will be reported upon completion of the drilling program.

Drill core recovery has been very good however; the drill contractor has experienced significant mechanical difficulties with its two drill rigs in completing the drill holes to designed depths in a timely manner.

All drill samples for this program are split in the field and held under appropriate security prior to transport to the ALS-Chemex preparation laboratory in Hermosillo, Sonora. All gold assays are prepared from the split core using 50-gram aliquots and fire assay with AA finish. Silver and 33 other elements are determined by standard ICP analyses. Neither silver nor the base metals (copper/lead/zinc) occur in significant amounts at the Marisol area; however silver and the lead sulfide galena, have been identified in rocks from the La Jarra area.
