The property consists of 19 claims totaling 7,472 hectares located between Todd and Surprise Creeks. Ownership of all claims is presently 50 % registered with Mountain Boy Minerals Ltd and 50 % Great Bear Resources Ltd...

The Surprise Creek property lies in the Stewart area, east of the Coast Crystalline Complex and within the western boundary of the Bowser Basin. Rocks in the area belong to the Mesozoic Stuhini Group, Hazelton Group and Bowser Lake Group that have been intruded by plutons of both Cenozoic and Mesozoic age. The Surprise Creek claim group is underlain by a sequence of Jurassic clastic and volcanic rocks which trend north-south to northwest-southeast. The area is dominated by a major anticline, which displays eastern vergence. An area located close to the anticline's axial plane is occupied by reddish to maroon andesitic volcaniclastic and volcanic rocks of Betty Creek Formation. To the west and east of the anticline's axis there are felsic rocks of Mount Dilworth Formation (?). They form horizon, 70-200 metres wide, composed of apple green, light grey or white coloured felsic volcanic rocks which include: flows, intrusions and pyroclastic rocks.

Types of mineralization found on the property include in place and in float include:
  • Extremely fine grained syngenetic pyrite, sphalerite and galena with high silver, mercury, and manganese hosted in black chert, limestone and mudstone.
  • Banded iron formation
  • Chalcopyrite and molybdenite bearing quartz-pyrite-pyrrhotite veins and pods related to intrusion of quartz monzonite.
Types of mineralization found in float only include:
  • Very strongly silicified trachyte/latite with pyrite, sphalerite, galena, and chalcopyrite.
  • Precious metals bearing quartz with pyrite, arsenopyrite, chalcopyrite, galena, sphalerite and tetrahedrite.
  • Quartz with sphalerite and galena.
The most promising type of mineralization found on the property to date consists of extremely fine grained syngenetic pyrite, sphalerite and galena with high silver, mercury and manganese hosted in black chert, limestone and mudstone. This type of mineralization can be found mostly in numerous boulders and to a much lesser extent also in place. Contents of zinc, lead, silver and mercury in these rocks vary in a broad range from slightly elevated values to highs of 7.61% for zinc, 1.1% for lead, 106 g/t for silver, and 33,800 ppb for mercury.

This type of mineralization has been traced intermittingly over a distance of 24 km on mineral claims that Mountain Boy Minerals has a 50 % interest in. At present, the Company is exploring a mineralized exposure called the "Ataman Zone" traced over 650 m of height, 600 m of width and over 1200 m of length.

Ataman Zone Mineralization

A 2016 program was focused on Ataman Zone where early in the field program the Mountain Boy crew found several angular boulders up to 1.0 metres in size composed of limestone/ mudstone with 1 to 15% sphalerite. Highlights of the program yielded the following:
  • Three samples collected from the above boulders assayed 3.04, 3.13 and 11.64 % zinc plus anomalous lead, silver, gold, arsenic and tungsten; gold assays averaged 90 ppb.

  • Close to the top of Ataman zone a six metres thick horizon of finally laminated exhalite with sphalerite mineralization is present. Five grab samples (KMJ-42 to 46) collected from this horizon averaged 23.4 ppm Ag, 0.34% Pb and 1.24% Zn.

  • Also in the top part of Ataman Zone a float sample AW-33 of breccia composed of chert and barite fragments cemented by limonite yielded 479 ppm Ag, 176 ppb Au, 2.45% Pb and 0.7% Zn.

  • Approximately 50 metres below, a composite sample of several grab samples from limestone/chert horizon at least 3-4 metres wide with extremely fine grained sphalerite returned 81 ppm Ag, 0.22% Pb and 5.53% Zn.

  • In the middle part of the Ataman zone several barite-carbonate veins and shear zones up to 25 metres wide were found. They carry from trace to 5% galena and sphalerite. A 1.0 m chip from a barite-carbonate vein with 1-2% galena and 2-3% sphalerite assayed 297 ppm Ag, 0.85% Pb and 3.10% Zn.

  • Close to Ataman zone a float composed of quartz, carbonate and 15-20% galena returned 7.88% Pb, 239 g/t Ag and 318 ppb Au. Another float sample collected from the same area of a sphalerite-pyrite vein assayed 26.12% Zn, 0.86% Pb, 592 ppb Au and 200 ppm Ag.
Two drill holes completed late in 2016 tested the large Ataman Zone located in Surprise Creek within the Golden Triangle district of British Columbia. Highlights of the drilling are as follows:
  • 4.58 m of 4.31 % Zn, 44.75 g/t Ag, 0.33 % Cu and 67 % barite in DDH SC-2
The remainder of assays include:

Hole # From(m) To(m) W(m) Au g/t Ag g/t Zn % Pb % Cu % BaSo4 %
SC-2 58.26 77.20 18.94 0.12 28.0 1.21 0.03 0.31 46.73
Incl. 58.26 62.84 4.58 0.11 44.75 4.31 0.05 0.33 67.0
Incl. 58.26 60.4 2.14 0.09 70.7 6.49 0.09 0.56 60.48


The drilling was terminated due to bad weather and freezing of the water source. DDH-SC-1 was drilled parallel to the zone and intersected low values. DDH-SC-2, drilled at right angles to the zone, was still in the mineralized horizon as the last assay had 73.47 % barite.
