SHM Announcement-Geological La Santas

TORONTO, CANADA--(Marketwire - March 19, 2008) - Southern Hemisphere Mining Limited (TSX VENTURE:SH) ("Southern Hemisphere" or the "Company"), is pleased to announce that further work at La Santas has indicated the existence of a mineralised copper porphyry.

Exploration work at the company's Las Santas project, located in the Salamanca district of Region IV in central-northern Chile is continuing and involves geological mapping, sampling and drilling.

As reported previously geological mapping and reverse circulation drilling has confirmed the existence of a previously unrecognised porphyry system within the project area, now referred to as the Cerro Marcoleta porphyry. Reverse circulation hole LSRC1 was drilled vertically to test a geophysical target. The hole intersected sulphidic porphyry from 26m depth to end of hole at 224m when the hole had to be abandoned because of poor drilling conditions.

Results from the mapping and surface chip sampling program have returned the following results:

Analyses were completed by ALSChemex at the La Serena Laboratory, an accredited analytical facility. Check and duplicate sample analyses confirmed that results were within acceptable industry limits for precision and accuracy.

These initial surface sampling results, in conjunction with the initial drill data suggest that the Cerro Marcoleta porphyry represents a significant and previously unrecognised mineralized copper porphyry system in the Las Santas property. Key components of the system recognised to date include a copper enriched central zone with a distal gold enriched hydrothermal breccia. Work is continuing to further define and evaluate the mineralized system.

Russell Birrell, the VP Exploration, designated as the qualified person defined by the National Instrument 43-101, prepared the data as described in this release.

About Southern Hemisphere Mining Limited

Southern Hemisphere is a South American focused resource company focused on exploring for large tonnage copper resources in Chile. The Company currently has four projects in Chile covering approximately 177 km2 of prospective exploration ground covering three mineralized porphyry copper systems. These projects, La Santas, El Arrayan, Mantos Grandes and San Jose, are all located within the Chilean copper belt and in the case of two of the projects are in close proximity to existing large copper or copper /gold mining operations.
