y Minerals Ltd.: 49.2 Grams Per Tonne Gold Over 18.45 Meters Intersected in DDH-UMON-2010-1

STEWART, BRITISH COLUMBIA--(Marketwire - Sept. 21, 2010) - Mountain Boy Minerals Ltd. (TSX VENTURE:MTB) reports reports more drill results received from the diamond drilling on the high grade gold bearing Montrose zone at its Red Cliff project in Northwestern British Columbia. The Red Cliff is a gold/copper property consisting of 8 Crown granted mineral claims situated in the Skeena Mining division approximately 25 miles north of the town of Stewart, British Columbia. The property is operated under joint venture and is owned 60% by Decade Resources Ltd. and 40% by Mountain Boy Minerals Ltd. At present, access is via drill roads off the paved highway 37A.

Locally fine visible gold is associated with a stockwork of quartz-chalcopyrite-pyrite stringers occurring along a 30 meter wide shear zone. Strong disseminated and fracture filled pyrite mineralization as well as galena-sphalerite-chalcopyrite-visible gold form an envelope to the above stockwork mineralization.

A total of 28 diamond drill holes have been completed on the Montrose zone within the Waterloo Crown Granted claim on the north side of Lydden Creek. The drill holes were on 5 different panels testing south of and beneath the area of drilling in 2009. Most of drilling was from pads 60 meters below and 100 meters south of the 2009 drill pads. The 2010-UMon-1 to 4 holes were collared 20 meters south of DDH-2009-Mon-5 and 6 and tested south of these holes. Results for another lower hole (DDH-2010-Mon-2) and the first 2 upper holes (DDH-2010-UMon-1 and 2) are as follows:

The interval in DDH-UMon-2010-1 is 2.18 g/t gold if the 0.3 interval of 2847 g/t gold is excluded. The results of DDH-2010-UMon-1 confirm the high grade nature of the structure in the area of DDH-2009-Mon-5 and 6. DDH-2009-Mon-6 intersected 24.7 meters grading 20.87 grams per tonne gold with 2.13 meters averaging 142.2 grams/tonne gold. The intersections are believed to represent 70% of true width.

Results for a further 24 drill holes testing the Montrose zone are pending. The Red Cliff joint venture committee is currently planning follow-up drilling on the Montrose zone this season. The Montrose zone is accessible by drill road and is within forest cover that will allow for drilling through the remainder of the year. Accordingly, the site is being readied for freeze up conditions.

Ed Kruchkowski, P. Geo., a qualified person under National Instrument 43-101, is in charge of the exploration program on behalf of the company. All sampled core is cut with a diamond saw and half then sent to be assayed by Assayers Canada of Vancouver, BC. Gold values are determined using fire assay methods. Samples with coarse gold are determined using a combination of gravimetric and fire assay methods.
