- Samples collected 285 metres to the north of the High-Grade Zone include 949 g/t silver.
- The new zone appears to be an extension of the historically mined area.
- Drilling to start next week: High-Grade Zone and new extension to be drill tested.
Vancouver, B.C. – Mountain Boy Minerals Ltd (“Mountain Boy” or the “Company”) (TSX.V: “MTB”; OTCQB: MBYMF; Frankfurt: “M9U”) announces that drilling is set to commence next week on its flagship American Creek property. Drilling will commence near the historic Mountain Boy mine and include testing a newly mapped area that is interpreted to be an extension of that zone.
The American Creek Project is centered on the past-producing Mountain Boy silver (MB-Ag) mine, located 20 kilometres north of Stewart in BC’s Golden Triangle.
Recent work included mapping and sampling along the cliffs north of the old mine, an area that had not previously been examined due to the difficult access. Geologists skilled in rock climbing have now traced the structure hosting the High-Grade Zone approximately 400 metres to the north.
Three samples collected from what is interpreted to be a northward extension of the High-Grade Zone were rushed for assay:
- Subcrop sample C0034056 assayed 456 grams per tonne silver with 2.2% copper and 0.4% zinc.
- Bedrock sample C0034057 assayed 949 grams per tonne silver with 2.7% lead and 0.3% copper.
- Bedrock sample C0034058 assayed 1% copper with 0.25% zinc and 20 grams per tonne silver.
These samples were collected from the cliffs 285 metres to the north of the High-Grade zone at approximately the same elevation (Figure 1; trace of the mineralized horizon). Several other samples from along this newly mapped exposure have been sent to the lab.

Two new drill pads are now constructed in locations that will effectively test the targets. The first pad, located near the previously outlined High-Grade Zone, will test the concept that the high-grade silver mineralization is partially controlled by high angle east-west striking structures that intersect the prominent shallow dipping south striking structure.
A second pad, 310 metres to the north of the first pad, will test the newly found mineralized zone. The holes will be drilled to intersect both the shallow dipping main structure and the high angle cross structures (Figure 2; plan map of drill pads and surface grab samples).
