Kings Canyon & New Butte - 2007 Exploration Program

Maestro began retesting and verifying the historic drilling data on the Crown property in the spring of 2007. Maestro completed five core holes to verify grades and establish geologic controls and sampling protocols.

Four of the core holes tested the historic resource area while a fifth hole tested a strongly mineralized exploration hole 3200 feet south of the historic resource area. The results of this effort are highly encouraging: 4 of the 5 core holes intersected more gold than did the associated RC holes. All material drilled was oxidized Carlin-style gold mineralization and would be expected to be amenable to low cost heap leach processing techniques; historic but unverified bottle role tests have shown recoveries of 68% to 85% on Kings Canyon rock. The core drilling results are tabulated below. (Note that the last column in the table, GT core/RC (Grade multiplied by Thickness of a core interval versus the equivalent RC interval), is a measure of the absolute difference in the amount of gold intersected.)

Among the highlights of the core drilling program are:

The highest grade drill interval ever reported at Kings Canyon: 2 feet @ 11.25 g/t Au in KCC07-01.
The highest grade five foot interval ever reported at Kings Canyon: 5 feet @ 7.7 g/t Au in KCC07-04.
An interval of 74.5 feet @ 0.63 g/t Au in KCC07-05, a core hole, versus approximately 70 feet @ 0.37 g/t Au in RC hole BMKC-3, a 60% increase in gold content when comparing core to RC gold grades.
An interval of 51 feet @ 1.02 g/t Au in core hole KCC07-02 versus 20 feet @ 0.83 g/t Au in RC hole KC-2, a 213% increase in gold content.

One of the more noteworthy results was hole KCC07-05. This was drilled about 3200 feet south of the main resource into an area, the Ace target, where several previous RC holes had returned strongly anomalous but sub-ore grade (0.37 to 0.43 g/t Au) mineralization. The core hole assays showed about 60% more gold, raising the grade to 0.63 g/t Au or 0.019 opt Au. There are several other prior RC drill holes nearby and along a northwest trend over 4000 feet long that also intersected strongly anomalous material. It is possible that this area contains much more gold than previously recognized and could eventually represent a separate resource area at Kings Canyon.

Maestro plans to follow up this core campaign with 10,000 to 15,000 feet of additional drilling in 2008. Numerous robust targets exist on the property outside the historic resource area. These targets consist of:

The Ace target area, with numerous sub-ore grade intercepts from Battle Mountain drilling.
Other areas outside of the historic resource zone with prior RC drill holes that showed strong gold mineralization (up to 190 feet with 0.223 grams/ton gold).
Several jasperoid-bearing mineralized faults that are visually similar to the fault believed to have guided fluids responsible for known resource mineralization.
Covered areas with anomalous soil geochemistry. Many of these targets are located in areas where the target stratigraphy is at shallower depths than the historic resource area which would enhance their economic potential.

Maestro can earn a 100% interest in the Kings Canyon resource area property by paying Crown Resources Corp. US$1,000,000 or the equivalent value in common shares of Maestro by the 7th anniversary of their option agreement dated Dec. 6, 2006, or on the commencement of commercial production. Maestro will also issue 75,000 shares upon each of the first through seventh anniversaries of the option agreement. Maestro also holds an additional 970 acres at Kings Canyon through an option agreement with Palladon Ventures Ltd.
