Superior Mining Intersects 0.45 metres of 45.8 g/t Gold & 3.79 kg/t Uranium at Mangalisa Property, Free State Goldfield, Witwatersrand Basin, South Africa


February 17, 2009

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 17, 2009) - Superior Mining International Corporation ("Superior" or "the Company") (TSX VENTURE:SUI) is pleased to announce that it has received assay results from an exploration drilling program at its Mangalisa property in the eastern part of the Free State Goldfield, South Africa.

SIGNIFICANT INTERSECTIONS:

PG-1 / 12    776.32 - 776.77 (0.45 m) @ 45.8 g/t Au & 3.79 kg/t U
  (Inc)      776.56 - 776.77 (0.21 m) @ 91.8 g/t Au & 7.24 kg/t U
PG-1 / 13    776.13 - 776.45 (0.32 m) @ 51.1 g/t Au & 4.27 kg/t U
PG-1:  Re-opened 1998 drill hole (UMT: 35J, X: 3,080,224, Y: 0,011,792,
       Elevation: 1,395 m AMSL, Direction: 263 degrees, Inclination: 85
       degrees)
 / xx: Deflection number. Deflections 0 to 10 were drilled in 1988. Core
       was not recovered from Deflection 11.

These results represent an important discovery for Superior, highlighting the presence of significant gold and uranium mineralization at much shallower depths than that found in the majority of mines currently operating within the Witwatersrand Basin. The highest gold and uranium grades are contained within a thin, small pebble conglomerate band and the associated carbon seam at its base. This reef has been named the 'Erfenis Reef' and forms part of a reef system that has been intersected at a depth of less than 800 metres (m). In comparison, Harmony Gold's operating Masimong gold mine, located less than 10 km south of Superior's property, produced 117,575 ounces of gold during the 2008 fiscal year from reefs approximately 2,000 m deep (www.harmony.co.za).

A total of seven pre-collar percussion holes plus three water wells were drilled initially (2,394 m drilled). Two of the percussion holes were then deepened by diamond drilling and one historical hole, previously drilled in 1988, was re-opened. Further work included the completion of wedging and deflection drilling of seven separate deflection intervals (1,350.6 m drilled by diamond drill). Refer to Figure 1. Samples were collected and analyzed from select intervals from two drill holes, PG-1 and ERF-1, and their respective deflections. Assay results from significant intersections in hole PG-1 are presented above. No other significant intersections were encountered.

Drilling of ERF-2 was suspended prior to completion pending receipt of analytical results and geological interpretation of core from PG-1 and ERF-1. The need for continued drilling of ERF-2 and the other four pre-collared holes (ERF-3, ERF-4, NGT-1 and NGT-2) will be reassessed based on the geological interpretation of the available core and assay results. These studies will form the basis for the next phase of exploration on the property.

The Mangalisa Project represents one of the last remaining, high potential gold and uranium exploration properties within the Witwatersrand's Welkom Goldfield. The results of this exploration program indicate the potential for the discovery of new gold and uranium mineralized reefs within the area. The reef, as revealed in PG-1, is a classic 'small-pebble, oligomict, carbon-rich and well sorted conglomerate' reef that is typical of the Free State. The general area remains prospective for other Free State gold reefs deeper in the stratigraphy, such as the 'A', 'B', Leader and Basal Reefs, which have been mined nearby at Harmony's Masimong Gold Mine.

Superior holds an 87% interest in the Mangalisa property through its 74% ownership position in Turquoise Moon Trading 403 Pty. Ltd., the South African company that holds the property, plus an additional 13% interest through its 49% ownership position in Middelvlei Gold Investments (Pty.) Ltd., a Black Economic Empowerment (BEE) company based in Johannesburg South Africa.

Quality Assurance and Control

All drilling of the zones of interest was carried out using either NQ wireline or TNW conventional technique diamond core drilling. The majority of samples for assay were taken from TNW size cores, in the form of half-cores that were cut by diamond rock saw. Pre-collar drilling through non-target lava sequences to depths of approximately 300 m was carried out using persussive drilling.

Full quality control QA/QC supervision and protocols have been implemented and adhered to by Snowden Mining Industry Consultants P/L of Johannesburg (core logging and cutting, sample preparation, and the insertion of 'blanks' and standards at regular intervals). Analytical work has been undertaken by Set Point Laboratories of Isando, Johannesburg and Performance Laboratories Pty Ltd of Randfontein, Johannesburg. At both laboratories, analyses for gold have been by 50 g sample weight, fire assay and ICP, with blanks and/or standards inserted. Analyses for uranium have been based on XRF and 'pressed disc'.
