Southern Hemisphere Mining Limited: Third Drilling Programme and Additional Tenements Purchase Both Successfully Completed at Los Pumas Manganese Project

VANCOUVER, CANADA--(Marketwire - Feb. 26, 2010) - Southern Hemisphere Mining Limited ("SH") (TSX VENTURE:SH) announces the drilling results from the third Reverse Circulation ("RC") drill campaign at the Los Pumas Manganese Project in Northern Chile and the exercise of the Sociedad Minera Kaiora International Limitada ("Kaiora") Option to complete the purchase of additional tenements that results in SH's wholly owned subsidiary, Minera Hemisferio Sur SCM ("MHS") having a 100% ownership of all the tenements constituting the Los Pumas Manganese Project.

Third Reverse Circulation Drilling Campaign

A total of 5,751 meters of RC drilling comprising 188 drill holes and 113 meters of diamond core drilling in 7 drill holes was completed.

To date a total of 9,253 meters have been drilled in 340 drill holes. In addition, a total of 652 meters of diamond core drilling had been completed in 32 drill holes.

Drill intercepts from the third RC drill programme are as follows:

Metallurgical Test Work

Dense media separation test work is being conducted on core samples from the first 25 diamond core drill holes, with results from this test work to be completed and reported in March 2010.

Previous test work on 22 subcrop samples and 16 drill chip samples indicated that a saleable grade product of 38% Mn can be achieved at acceptable mass yields.

Resource Estimate

The first two RC drilling campaigns completed 3,502 meters of drilling in 152 drill holes. An independent assessment of the resource resulted in an inferred resource of 14.63 million tonnes at a grade of 9.98% Mn. A review of the Los Pumas Project resource, with the inclusion of the results from the third drill campaign, is underway and will be reported during March 2010.

Purchase of Additional Los Pumas Tenements

At the end of January 2010, MHS, a 100% owned subsidiary of SH, exercised an existing option and made a final payment of USD $700,000 which completed the purchase of additional tenements from Sociedad Kaiora. These two mining licenses being "Emanuel del 1 - 20" and "Awahou 1-20", result in MHS now having 100% ownership of all the tenements constituting the Los Pumas Manganese Project, which covers 136 square kilometers.

Qualified Person

The above drilling and sampling programme was under the direct control of Mr. Igor Collado SH's Vice President of Exploration and Senior Geologist. Mr. Collado has over 20 years of experience in the Chilean mining and exploration industry and has been designated as a qualified person, as defined by National Instrument 43-101.

Trevor Tennant, with considerable experience in the manganese mining industry, has visited the site on several occasions during this drilling program and has been responsible for the compilation of all technical information with respect to this news release.

“Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.”
