SENTULA Operational update for GEOSEARCH-BUENTI Drilling in South Africa SENTULA MINING LIMITED Incorporated in the Republic of South Africa (Registration number: 1992/001973/06) Share code: SNU ISIN: ZAE000107223 (“Sentula”) SENTULA OPERATIONAL UPDATE FOR GEOSEARCH-BUENTI DRILLING IN SOUTH AFRICA In light of the ongoing challenges facing the platinum group metals sector in South Africa, and the commensurate reduction in exploration expenditure, Geosearch, a wholly-owned subsidiary of Sentula and its Broad Based Black Economic Empowerment joint venture, Buenti Drilling, has experienced a significant curtailment of its South African drilling operations. This will affect Geosearch’s performance in the second half of this calendar year and with limited visibility of future tenders in this sector, the adverse operational and financial impact is envisaged to extend through to the end of the present financial year, ending 31 March 2013. Taking cognisance of these trading conditions, Geosearch’s domestic business unit is being restructured. Notwithstanding the operational challenges experienced at the Jwaneng site, which have impacted Geosearch’s Botswana business during the first part of the current financial year, exploration expenditure, predominantly for Gold and Coal, throughout the rest of the continent, remains in line with previous forecasts.
