- Initial MTB field-work confirmed the historic showings and identified new zones of interest, some of which were ice-covered at the time of the previous work.
- Identification of a large zone of intense hydrothermal alteration.
- Samples with multi-gram gold and strong base metal assays demonstrate mineralization over an extensive area.
- Receding glaciers has opened up large areas that have never been explored.
- The property has potential for precious metal veins, skarn and VHMS-style mineralization.
The Mountain Boy team has compiled the available historic data and conducted an initial on-site review of the project. The team spent 8-man days mapping the geology, alteration and structure as well as sampling outcrop for geochemical analysis. Samples taken validate historic assays and outline new areas of mineralization. The results point to the presence of mineralized systems similar geologically and in scale to other large deposits in the region.
Mineralization within the large gossan identified in 1990 has been extended 500 metres to the southwest. The gossan is interpreted as a northeast trending, structurally controlled, hydrothermal alteration conduit consisting of quartz + sericite + pyrite alteration with minor arsenopyrite and up to 1,260 ppb gold and 41.4 ppm silver. Significant base metal values were also encountered within the gossan. The best gold numbers appear to be associated with pyrite. Mineralization has been traced for 1,300 metres on surface. Additional structurally controlled alteration zones with up to 2,920 ppb gold were also mapped in the northern portion of the claims.
Samples from Mountain Boy’s initial program are also anomalous in pathfinder elements such as antimony, mercury and arsenic. Barium is also anomalous in some areas and is a commonly associated with volcanic hosted massive sulphide deposits (VHMS). The property has had very little exploration on it to date and the potential for more discoveries is high.
Three styles of mineralization have been identified. These include the following;
- Structurally controlled precious and base metal mineralization as found in the large gossan and the other veins to the north.
- Bedded massive sulphides of copper, lead and zinc.
- Massive sulphides within skarn identified in 1990 but not visited in the 2019 program.
Since 1990, the glacier separating the two gossans has retreated 1,200 metres and thinned substantially, exposing many new outcrops. The BC Assessment Report index contains no other records of work performed on the claims since 1990.
OWNERSHIP: 100% owned
LOCATION: Located 40 km northwest of the historic Eskay Creek Mine
INFRASTRUCURE: 7 kilometres south of the completed Galore Creek access road and 30 kilometres west of highway 37 and the Northwest high-voltage transmission line.
PRIOR WORK: In 1990, Blue Gold Resources carried out a small exploration program of prospecting, geological mapping and rock sampling on the current claims. They identified two large gossans separated by a large glacier with pervasive silicification and pyrite alteration. Copper, lead, zinc, silver and gold mineralization was discovered within the alteration zones. Magnetite skarn mineralization with sphalerite and chalcopyrite was also discovered to the east of the large gossan. Rock samples from the 1990 program assayed up to 13.58% copper, 1.06% lead, 12.4% zinc, 2,500 ppb gold and 50.0 ppm silver. Samples were also anomalous in pathfinder elements such as antimony, arsenic, cadmium and bismuth (BC Assessment Report No. 21008).
In 2019, Mountain Boy Minerals conducted a short exploration program on the program confirming and expanding on the 1990 program.
- Airborne Time Domain Electromagnetic and Magnetic Survey (Skytem) and interpretation.
- Continued prospecting, geological mapping and sampling.
- Lidar of the property.
- Lead isotope geochronology on galena from mineralization.
- Drilling of identified targets.
