Mountain Boy Minerals drills 15m of 66.8% and 26m of 41% BaSO4 including 4.5m grading 3.27% Zinc, 0.71% Lead and 22 grams of Silver at Surprise Creek

VANCOUVER, British Columbia, Jan. 31, 2018 (GLOBE NEWSWIRE) -- Mountain Boy Minerals Ltd (TSX-V:MTB) (Frankfurt:M9U) (“Mountain Boy”) is pleased to report on two shallow drill holes completed on the Ataman zone within the 100% owned Surprise Creek VMS/barite claim block in the Golden Triangle area of British Columbia.

The Surprise Creek property covers an area of approximately 12 km of known VMS (“Volcanogenic Massive Sulphide”) style mineralization generally hosting copper, zinc and lead, with some gold and silver. Folding within the Surprise Creek claims has resulted in repeated sections of prospective VMS horizons. Anticlinal structures have resulted in the prospective VMS horizon being present along both the west and the east sides of the Surprise Creek claims. There are at least six separate VMS boulder trains or showings on the Surprise Creek property. The Company website at www.mountainboyminerals.ca shows the location of the VMS style of mineralization.

Abundant barite is common on the Surprise Creek property. It is a common constituent of Kuroko style VMS systems forming layers above the base metal-silver mineralization. To date only 4 short drill holes have tested the barite rich portion of the Ataman zone at the headwaters of Surprise Creek.

The objective of the 2017 drill program at the Ataman zone - Surprise Creek VMS target was to define the location and direction of the stratiform barite cap within the system. This will help the Company in conjunction with the interpretation of the VTEM survey to define drill targets for the 2018 program. The key targets are high grade mineralized sulfide lenses or zones within the system which are mostly distal but directly related to the barite occurrence. In the accepted model for sedex hosted deposits, the barite would be the first mineral to come out of the vents followed by a sphalerite rich zinc and silver zone. Hematite, calcite, bornite and chalcopyrite mineralization are precipitated last.

It is noteworthy that zinc, lead, copper and silver, as well as low amounts of gold are present in the barite cap in the form of small zones and veinlets which could be the result of a subsequent hydrothermal event bringing the sulfide minerals to surface. Surface sampling has shown that the barite cap or horizon extends for at least 650 m of height and at least 150 m of length. To date, the source of large angular zinc boulders up to 1 m in diameter, assaying over 7% zinc, has not been located. These boulders are located in the immediate vicinity of the barite zone.

Detailed results of the 2017 drilling are shown below:

At the Howards Pass lead zinc mine in the eastern Yukon, which has characteristics analogous to mineralization at Surprise Creek, the main deposit is directly positioned under the main barite zone.

Mountain Boy is most encouraged from the results in light of the extensive and numerous showings that require further work.

The barite in itself is significant as the Company has demonstrated that a high quality product can be achieved through floatation with significant base and precious metal recovery. Barite is used by the oil and gas industry as a weighing agent in drilling muds and there is a large production shortage in North America. With increased oil and gas prices drilling activities have increased and demand and prices for barite are rising. With the deep water port of Stewart, B.C. within half an hour of trucking from the deposit, Mountain Boy could compete on the international markets. Barite is currently selling from US$120 to US$180 per ton depending on the location and would add considerable value to the economic potential of a silver base metal operation at Surprise Creek. The world barite market is estimated to steadily increase from US$2.2 billion in 2016 to US$4.1 billion by 2024 according to Global Market Insights, Inc. of Delaware, USA.
