April 23, 2008- King's Bay Gold Corporation (TSX.V: KBG) and Mainstream Minerals Corporation (TSX.V-MJO) are pleased to announce that high grade gold intervals characteristic of a Red Lake vein type deposit have been intersected in Hole 25 at their joint-venture Bobjo Mine project, located in Earngey and Agnew Townships, Red Lake, Ontario.
Results Confirm Extension of Zones and Confirms Depth Extension
This project continues to be the site of new discoveries that so far included high-grade gold, strategic rare metals and rare earth elements. The partners are now pleased to report the discovery of a new high-grade gold zone located approximately 150 metres South of the main zones at a depth of 291.0 to 293.0 metres. The results extend existing mineralized zones and confirm depth extension.

The partners are also pleased to report that a third drill rig is now at work at this Bobjo project. A large 15,000 metre drilling program is well underway and more assay results will be announced very shortly when received and verified.
This Bobjo Mine project is located between the former South Bay Zinc / Copper Mine and Uchi Lake Gold Mine. It is noted that an existing power line passes through the southern part of the property and that it is within trucking distance to the Placer Dome / Goldcorp Mill in Red Lake, Ontario. It is comprised of 259 claim units totaling 10,360 acres. The area has a history of gold and base metal production dating back 80 years. The work presently being carried out by the partners represents the commencement of the first modern, systematic exploration of the property in the last 80 years when a two compartment shaft was sunk to 270 feet with two levels in 1929.
The partners are very pleased with the results of the holes reported to date on this Bobjo Mine Project. All zones are open in all directions and at depth. Included in the following table are the results of all holes received to date by the partners at this Bobjo Mine Project:

Rare Metals and Rare Earth Elements - Demand and Uses
Demand for rare metals and rare earth elements is soaring because of consumer demand for more fuel-efficient cars, alternative energy technologies such as fuel cells, the nuclear power industry for both practical and experimental utilization, rechargeable batteries, lasers, hydrogen storage, superalloys as used in the aerospace industry, televisions, cellular telephones, computer screens, permanent magnets as used in electric-hybrid vehicles and in the conductor industry for many of the new "Green" technologies, etc. Currently, 97% of the world supply of the Rare Earth Materials (REM) comes from China. China recently announced a reduction in the exports of REMs coming out of their mines. This decision will considerably reduce the supply for buyers outside of China while world demand is in full growth.
The main consumers of rare earth materials are in South-East Asia (Japan, Korea, Thailand, China) and in the USA. The United States used to be the largest consumer of rare earth materials, about 27% of the world's total. However, in recent years, China became the number one global consumer, exceeding the American consumption. The United States currently imports nearly 100% of their needs in REM, and the American market for rare earth materials is valued at more than 1 billion US dollars per year. It will soon become critical to produce these resources outside of China.
It is reported that 77% of world production is currently coming from one mine in China. The United States used to produce approximately 6% of the world's supply from one of the only in-situ rare earth mines in the world, at Mountain Pass, California. However, Mountain Pass — the only producing mine in North America — ceased operations several years ago, creating a situation where there is no Rare Earth Elements production taking place in North America, or anywhere significant outside of China. Therefore prices and demand are expected to continue to rise drastically.
