Superior Mining International Corporation: Significant Gold Results Encountered From Drilling of New Zealand Ross Alluvial Property

VANCOUVER, BRITISH COLUMBIA--(Marketwire – Oct. 13, 2009) - Superior Mining International Corporation (the "Company") (TSX VENTURE:SUI) is pleased to announce results from reverse circulation (RC) drilling of its Ross placer gold property on the West Coast of the South Island of New Zealand. The Ross property, located 1.5 km to the south of the Victory property (SAI October 8, 2009 news release), consists of Pliocene-aged alluvial gold leaders peripheral to current or historical mining operations.

Significant high grade gold intercepts were reported from a number of shallow reverse circulation (RC) drill holes. The most impressive of these included:

RC 03 graded 5.45 g/t over 1 metre from 21.0 metres
RC 01 graded 1.37 g/t over 3 metres from 1.0 metre

A limited program of reverse circulation (RC) drilling consisting of six (6) widely spaced holes (Figure 1), was carried out in the northern half of the property based on positive indications of gold bearing alluvial horizons. Three holes (RC01, RC03 and RC04) intersected auriferous gravels, whilst the remaining three holes intersected non-prospective Pah-pah shallow marine sediments. Results are detailed in Table 1:

Preliminary drilling has identified the presence of southerly trending auriferous leaders that although are confined in the north, have greater volume potential in the central and southern parts of the property areas. A further round of drilling will be undertaken to test tonnage and grade potential, which, if positive, would allow the Company to establish its own mining operation, or provide "feed" to a nearby (less than 1.0 km trucking distance) operation.

The Ross Property comprises gold placers found in the Pliocene Old Man Group gravels, thought to represent erosional products of cyclic outwash deposits and moraine fronts of successive glaciers. The Old Man Group comprises three units, with the upper most member (Humphrey's Conglomerate) considered to the most prospective for gold placer concentration. Historical mining of "stacked" gold leaders from this unit and to a much lesser extent of the underlying Jones Formation and Donnelly Conglomerate, immediately to the north of the property, reported gold production of 168,000 oz (1890-1920) and 130,000 oz (1985-2002). Remnant gold leaders of the Humphrey's Conglomerate are still visible today in the southwestern pit wall. Mapped southern extensions of the Humphrey's Conglomerate (Hancock, 1980), together with the presence of 1900's sunken shafts (to maximum depth of 125 m) on the southern property margin, clearly demonstrate the resource potential. As a result the Company undertook a series of excavator-dug trenches and test pits in the northern portion of the property (closest to the 1985-2002 dug pit) to confirm this concept prior to the commencement of the RC drilling.

The West Coast has contributed approximately 25% of New Zealand's annual gold production over the last 10 to 15 years. Total reported placer production is in excess of 9.0 million ounces. All of the gold produced in this region since the 1950s has come from placer deposits. The West Coast is a long narrow region confined between steep mountain ranges to the east and the Tasman Sea to the west. In between are foothills to the main ranges, terraced river valleys and a narrow, discontinuous coastal plain. Gold-bearing alluvial deposits are situated primarily in the lower lying areas beneath river/stream floodplains, on terraces flanking the floodplains and on raised marine terraces (Rose, 2000). Since 1980 there have been a large number of successful small and medium-scale gold recovery operations using hydraulic excavators and mobile gold recovery plants.
