King's Bay Gold Ultra High-Grade Gold Discovery Grading up to 2,942.7 and 806.9 Grams Per Ton, Red Lake

WINNIPEG, MANITOBA--(CCNMatthews - Dec. 11, 2006) - King's Bay Gold Corp. (TSX VENTURE:KBG) and Mainstream Minerals Corp. are pleased to announce the discovery of many new ultra high-grade gold veins at the Bobjo Mine, Dent and Earngey Townships, Red Lake District of Ontario. Surface grab sampling of one vein, with a width of approximately 6 metres, has just returned ultra high-grade gold values of up to 2,942.7 g/t (85.84 oz/t) and 806.9 g/t (23.54 oz/t) from amongst the samples taken.

The partners have just recently completed a ground stripping program using a bulldozer and a backhoe. As a result, many new gold bearing quartz veins, shears and stringers were exposed. Of the many new dozens of criss-crossing gold bearing entities only a dozen or so have been sampled to date. Most flat lying veins could not be sampled properly so a channel sampling program will be carried out in the not too distant future.

Only approximately 80 acres have been stripped to date. However the partners intend to strip an additional 200 more. Presently, more claims are being staked and a geophysical survey (Mag/VLF) will be carried out over the entire land mass as well as over the ice on both sides of the peninsula.

Other veins and stringers also returned very high-grade gold values including 55.34 g/t (1.61 oz/t), 42.65 g/t (1.24 oz/t), 42.37 g/t (1.23 oz/t), 36.89 g/t (1.07 oz/t), 36.23 g/t (1.05 oz/t), etc.

All grab samples were taken from mineralized quartz vein material, shears and contact material between the veins and mafic volcanics under the help and strict supervision of John Archibald, P.Geologist, Ron Rivet exploration coordinator for King's Bay and Gerald L. Colborne, B.Sc., M.Sc., P.Eng., P.Geol., F.G.A.C., M.C.I.M.. Mr. Colborne is the Qualified Person under NI 43-101. All of the samples were analyzed by Accurassay Laboratories of Thunder Bay, Ontario, using the standard fire assay method.

The latest batch of surface grab sample results are as follows:

The partners are extremely pleased with these developments, especially with the discovery of these new very high-grade gold bearing veins that have never been seen or tested before. The area has a history of gold and base metal production going back as far as 80 years and the work presently being carried out by Mainstream and King's Bay represents the commencement of the first modern, systematic exploration of this property.

The Bobjo Property is located between the former South Bay and Uchi Lake gold mine along the east limb of the Confederation Assemblage. It is comprised of a total of 9 patented claims and 17 claim units with a major power transmission line passing through the southern part of the land package. The partners are planning a large and aggressive exploration program to commence in early 2007.
