STEWART, British Columbia, July 05, 2017 (GLOBE NEWSWIRE) -- Mountain Boy Minerals Ltd (“Mountain Boy”) (MTB.V) (M9U.F) reports that Phase I drilling is continuing on the Red Cliff property. On the Red Cliff project, the Company and Decade Resources are in joint venture on the Crown Granted portion of the property which is owned 65% by Decade and 35% by Mountain Boy. The Silver Crown 6 claim, in which Decade is earning a 100 % interest, is adjacent to the north portion of the crown grants. To the north of the Silver Crown 6 claim, Mountain Boy owns a 100 % interest in the MB property. The Red Cliff Extension claim owned 100 % by Decade is along the east side of the Silver Crown 6 claim.

Drilling on the Montrose zone has intersected a wide mineralized intrusive within red tuffs forming the Betty Creek formation. The Company has used a just completed petrographic study which is greatly aiding the 2017 exploration.  Based on thin sections examination of mineralized rocks from both the Red Cliff zone and Montrose zone, the following information was obtained:

1) Mineralization is associated with intrusions of porphyritic latite to trachyte.
2) Late alteration-mineralization events led to the deposition of quartz, carbonates, pyrite, magnetite, chalcopyrite, galena, specularite, sphalerite and gold.
3) The presence of magnetite and Fe-rich chlorite as well as an undulating, wavy pattern of some the veins indicates a high temperature (hypothermal) environment.

Using this information, the Company has continued drilling holes which still contained the intrusive whether it was mineralized or not. As a result, all holes on the Montrose were continued past areas where previous drilling would have been terminated. All three holes completed on the Montrose zone contain visible gold at depths deeper than expected. The 3 holes have tested a zone up to 150 m in vertical height in an area that had not been tested previously.

The latest hole drilled at minus 50 degrees and at right angles to the zone was off the same set-up as hole 1 and 2. It intersected almost 100 metres of weakly sheared and brecciated intrusive with mineral zonation occurring from 150 to 250m in depth. Along the upper intersection, weak disseminated pyrite is present with local quartz-amethyst-galena-sphalerite-chalcopyrite-pyrite stringers in zones up to 5 m. At 163 m core length, fine visible gold is noted in galena-sphalerite stringers. From the top mineralized zone, short galena-sphalerite sections are noted to 218 m where the hole intersects a 18 m section of quartz-amethyst-galena-sphalerite-chalcopyrite-pyrite stringers. At 227 and 229 m, visible gold is noted within the galena-sphalerite veinlets. At the termination of the galena-sphalerite veinlets, chalcopyrite-pyrite veining is present along the bottom chill margin of the intrusive as well as the baked contact of the red tuff. The chalcopyrite-pyrite veining is present over a 10 m length. True width of the intrusive appears to be at least 70 m in DDH-Mon-17-3. Photos of the gold bearing galena stringers as well as chalcopyrite-pyrite stringers are included below.

On the Red Cliff zone, located 900 m south of the Montrose drilling, the Company has completed 3 holes. The holes contain a 5-6 m wide mineralized zone with strong chalcopyrite-pyrite within quartz veins and silicified intrusive.
