Mosquito Consolidated Gold Mines Limited is pleased to report excellent results from the last hole of the 2009 diamond drilling program for its Idaho-based CUMO molybdenum/copper project.
Hole 53-09 is an angle hole (-75) drilled to a depth of 753.2 meters (2471 feet), bearing 015 degrees azimuth from the same site as Hole 45-08 (which was incomplete) The hole is designed to extend to the south the mineralized zone intersected in Hole 47-09 (figure 1). Hole 53-09 intersected good copper mineralization from 12.2m (40 feet) to 753.2m (2471) feet and molybdenum bearing mineralization from 243.8 (800 feet) to 753.2m (2471) feet. The hole confirms that the copper mineralization is increasing to the west, while the molybdenum mineralization continues to the south and southwest, thus expanding the mineralized zone.
Assay results returned include:
Hole 53-09 509.3 meters (1671 feet) grading 0.19% Cu and 0.091% MoS2
(0.97% Cu Eq., 0.108% MoS2 Eq., 1.94 lbs MoO3 Eq/t)
Including 292.1 meters (961 feet) grading 0.15% Cu and 0.115% MoS2
(1.07% Cu Eq., 0.119% MoS2 Eq., 2.14 lbs MoO3 Eq/t)
(Note: As a result of the recent Preliminary Economic Assessment (Ausenco), the calculation of equivalents has been changed to include recoveries (see formulas below Table 1), this results in lower equivalent grades when compared to the previously announced holes.)
The entire core for the hole was sampled and cut in half using a diamond saw. Half the core was sent for analysis and the other half has been kept and stored at the core facility located on site. Following cutting, the samples were delivered directly by Mosquito personnel to either ALS Chemex or SGS Labs, both located in Elko, Nevada and fully accredited analytical laboratories. They were first analyzed for 47 elements using a four (4) acid digestion with analysis by Inductively Coupled Argon Plasma Optical Mass Spectrometer (ICP-MS). Copper and Molybdenum bearing samples were then checked by using a larger five gram sample and analyzed using pressed powder pellet X-Ray Fluorescence Spectroscopy (XRF). In addition, duplicates, blanks, and standards were analyzed to ensure analytical accuracy and reproducibility. All rejects are being kept for further analysis and for use in metallurgical testing.
Geologically, hole 53-09 indicates that the overall copper grade of the older porphyry copper system is increasing to the west and the Molybdenum bearing mineralization is continuing to the southwest. The copper-silver section of hole 53 averaged 0.22% copper over 428.1m (1404.5), which is the highest copper grade intersection on the property to date.
Overall the drilling in 2009 to date has indicated the limits of the north, northwest and south extents of the mineralization. The east, south-east, west and south-west are still wide open for exploration. The older copper bearing mineralization increases east to west, while the younger molybdenum system increase west to east. The two systems are starting to separate to the west with the older copper-silver-gold system trending to the west and the molybdenum bearing system following the porphyry dykes to the southwest. These observations will prove extremely useful in planning the upcoming 2010 drill program.
Full summary of the analytical results for Hole 53-09 are outlined below in Table 1. Mineralization consists of copper, molybdenum, silver, rhenium and gallium. As a result of the multi-element nature of the mineralization, it was decided to calculate both a copper and molybdenum equivalent for the intercepts. Both equivalents are required as the deposit is zoned as described above. Please see notes below table for explanation of the calculation of copper equivalent (Cu Equiv.), MoS2 equivalent (MoS2 Equiv.). The presence of the by-product elements gold, silver, rhenium, gallium and tungsten is very significant in terms of the development of the property.
The table below lists the location and orientation of the current drill holes. All holes are being surveyed down the hole using a Reflex survey instrument.

The 2009 program completed 7 holes, and the results will be used to expand the existing 43-101 resource and to convert the additional areas of the current resources to measured and indicated.
In other events, the final draft of the environmental assessment has been sent for review to the United States Forest Service for final review, once complete the report will be published and the public review period will start with the aim of obtaining the next exploration permit by May.
Finally discussions are still on going with several groups interested in fully funding the CUMO feasibility study.
