Maestro Completes Phase One Drilling at Caldera, Nevada

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 12, 2007) - Maestro Ventures Ltd. (TSX VENTURE:MAP) announces today that it has completed a first phase drill exploration program at the Caldera Project in Nye County, west-central Nevada.

The Caldera Property covers an area of approximately 2,606 acres in the southern Shoshone Range, located in west-central Nevada, in the southwest portion of the Great Basin. The project area displays a large area of hydrothermal alteration with widespread strong geochemical anomalies. The mineralization style at Caldera is that typical of an epithermal volcanic-hosted precious metal system with gold and silver dominant in fault zones, silicified breccias, and stock work zones. High-grade values in drill intercepts and surface samples indicate that a bonanza-vein system may occur similar to the nearby Round Mountain Mine or the Midway project and are the primary focus of exploration. Thicker lower-grade drill intercepts suggest that bulk tonnage targets also exist.

The drill program consisted of 8,885 feet drilled in 24 reverse circulation drill holes. All the drilling was located in the northwest portion of the property in the vicinity of previous good drill intercepts or surface samples. Two planned sites could not be drilled due to difficult access.

The drilling intersected numerous narrow to broad zones of low grade gold and silver mineralization with one high grade intercept. The best results include 5 feet at 9.03 g/t Au and 163 g/t Ag in hole CD07-24, 55 feet at 0.644 g/t Au and 10.5 g/t Ag in hole CD07-13, 10 feet of 2.73 g/t Au with 17.7 g/t Ag in hole CD07-02, 20 feet at 0.99 g/t Au and 32 g/t Ag in hole CD07-03, and 20 feet at 0.73 g/t Au and 19.7 g/t Ag in hole CD07-23. All significant results are tabulated below.

The drill program did not return as many high grade intervals as was anticipated. However, it continued to demonstrate the strength of the system at Caldera, as 48% of the assayed intervals contained at least 25 ppb gold and 44% contained at least 1 ppm of silver. It should also be noted that the drilling only tested a small portion of the property, approximately 10%, and to limited depths: the maximum vertical penetration was about 500 feet. Numerous highly mineralized areas remain to be tested on other portions of the property.

All samples were collected at the drill site under the direct supervision of Maestro personnel and transported to secure storage area by Maestro personnel. They were collected their by ALS Chemex and transported to their Elko facility for preparation. Samples were analyzed by fire assay for gold and ICP analysis for other elements. Ten samples were re-analyzed by screen metallic assay for gold and fire assay for silver with no appreciable differences from the original results.

The technical content of this news release has been reviewed by Mr. Rick Russell who is a Qualified Person as defined by NI 43-101.

Allan Williams, President of Maestro Ventures Ltd., comments: "We learned a lot from this first pass drill program. We plan to leverage that knowledge to develop more compelling drill targets for our next campaign. It's a large system with a big precious metals budget that we think still has great potential."
