Highlights from the 32 holes drilled by the partners to date at the high-grade gold discovery area included:
53.61 g/t Au over 2.45 metres32.95 g/t Au over 1.10 metres27.43 g/t Au over 1.00 metres19.61 g/t Au over 2.00 metres18.18 g/t Au over 0.50 metres14.55 g/t Au over 1.00 metres12.80 g/t Au over 0.50 metres12.01 g/t Au over 0.50 metres8.70 g/t Au over 1.10 metres9.45 g/t Au over 1.00 metres8.45 g/t Au over 3.40 metres6.84 g/t Au over 1.00 metres6.25 g/t Au over 1.50 metres5.77 g/t Au over 3.00 metresDetailed gold results of all thirty two holes drilled by the partners to date can be seen at:
http://www.mainstreamminerals.com/site/properties/bobjo/resultsaubobjo.pdf
The partners drilled 10 exploratory holes 2 kilometres south of the main discovery area at the bottom end of the property. All ten holes intersected wide zones of anomalous Platinum values. This area will need to be investigated further.
The 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. The joint venture is 50 % Kings Bay Gold (TSX.V: KBG) and 50 % Mainstream Minerals (TSX.V: MJO) with Mainstream Minerals being the Operator of the project.
Andrew Gracie, Ph.D, P. Eng, P.Geo is the Qualified Person under National Instrument 43-101. All of the samples herein were analyzed by Acurassay Labs using the Neutron Activation Method and Acqua Regia Digestion with an ICPAES finish and standard fire assay for gold. True widths are not known.
The partners are pleased with the progress made to date at this project and with the fact that drilling has so far intersected gold in twenty seven out of thirty two holes from surface to a depth of 312 metres so far, which included high-grade gold in many intersections. All zones are open at depth and in all directions. The rare earth elements, rare metals, and other minerals were a surprise on this gold project and will definitely need some follow up drilling.
Most of the veins tested so far ran in an east-west direction. The area just north of the high-grade gold discovery is also host to many other quartz veins that have not been tested as of yet, including a 2 metre wide quartz vein than is running in a north-south direction. Grab samples from this vein yielded results as high as 115.00 g/t Au.
The partners are planning an aggressive Phase 3 exploration program for this exciting project in the near future and Mainstream Minerals is planning on commencing a financing very shortly.
