TSX-V: SUI VANCOUVER, June 22 /CNW/ - Superior Mining International Corporation, formerly "Superior Mining Corporation", (the "Company" or "Superior") announces that it has engaged Snowden Group of Johannesburg, to conduct an updated review of the resource estimate on the reef section of the Middelvlei property called the Black Reef which is part of the Middelvlei JV Project located on the West Rand Goldfield of the Witwatersrand Basin of South Africa. Graham Greenway, BSc (Hons) Geology University of Natal, MSAIMM, MGAA, Divisional Manager is the Qualified Person that will be preparing the report. Graham is a geologist with more than 13 years experience in the African mining industry. His career includes experience as a Mine Geologist in gold, tin, copper and uranium, as well as an Exploration Geologist working in the Bushveld Complex of South Africa and as a Resource Evaluation Geologist for Gold Fields including projects ranging from West African Witwatersrand type multiple reef gold deposits, coal, porphyry copper-gold to massive sulphide base metal deposits. His most recent posting has been as Chief Geologist for the opencast R¿ssing Uranium mine in Namibia before joining Snowden in February 2003. It is expected that the NI 43-101 compliant technical report concerning the Black Reef will be available within 45 days at which time the Company will provide an updated resource estimate by way of follow-up news release and will file the technical report on SEDAR. The Middelvlei JV Project is owned and operated by Pamodzi Gold, in which the Company's South African subsidiary holds a 50% interest. As disclosed in the Company's news release dated April 12, 2006, Pamodzi Gold has completed an exploratory diamond drilling programme on two additional reef horizons on the Middelvei property called the Ventersdorp Contact Reef (VCR) and the Middelvlei Reef. These two additional reef horizons will not be included in the technical report to be prepared by the Snowden Group. The Company has not yet received any drilling results from Pamodzi and is not expected to until resource modelling has been completed and appropriate reports have been prepared. The Company hopes to coordinate with Pamodzi the commissioning of an appropriate technical report, which also meets the requirements of NI 43-101 in respect of these additional two reefs, which will provide a further updated resource estimate on the Middlevlei JV Project. The Company wishes to confirm that preliminary preparation work for the Middlevlei JV Project has now been completed which included removal of initial top soil to expose the Black Reef horizon for ongoing appraisal, grade control, and geological mapping. A Toll Milling Agreement has been formally concluded with Harmony and the ore will be transported to and treated at the nearby Doornkop Plant. Construction of an ore handling system to feed into the Doornkop Plant is progressing and is expected to be completed early in the third quarter of 2006. The Company is an early stage exploration and near term producer focused on the mining of gold deposits in the central Witwatersrand region of South Africa.
