The Upper Groove Ridge gossan is situated on the southern slope of Johnny Mountain, approximately nine kilometres southeast (163°) of the Bronson Airstrip on the Iskut River.

Part of the SnipGold 2014 program consisted of prospecting and rock sampling from this area, which was identified by BCGS geologists as being at the northern portion of the Sky Fault System. This thrust system is believed to have played a significant role in the mineralizing events in the area, and given the 100% exposure of the Upper Groove Ridge area above the tree line, and the extensive gossan observed from the air and orthophotos, it was prioritized for reconnaissance level prospecting. The area of the gossan of interest, approximately 400 metres by greater than 1 kilometre, exhibits intense alteration and very well-developed shear fabric. A total of 44 rock samples were collected. Only four of the collected samples assayed more than 100 parts per billion Au, with the highest gold value reporting 0.385 gram per tonne Au. This suggests that although there was likely high hydrothermal fluid flow, there was weak mineralization in this locale. The elevated gold values correlate with an increase in secondary silica content (Assessment Report 35126).
