The area of the Root zone is underlain by andesitic rock of the Lower Jurassic Unuk River Formation of the Hazelton Group. A northwest trending belt of folded volcanic rocks contain a thick sedimentary sequence infolded along a synclinal axis.

The Root Zone was located in an overburden-covered area at the base of an up-rooted tree. It is located just east of the major regional Union fault. The zone is poorly exposed with forest cover both to the north and south of the zone. A grab sample of mineralized sub-crop indicated that sheared andesite contained a weak quartz-calcite with 5 per cent pyrite, 1 to 2 per cent sphalerite and minor galena.

Work History

In 2003, Mountain Boy Minerals conducted prospecting and trenching on Terminus (MINFILE 104B 002) and near Noname Lake. Mountain Boy and Pinnacle Mines completed a total of 288 meters of trenching on the Silver Coin property mostly on the Silver Butte area (MINFILE 104B 150). In 2005, Mountain Boy Minerals and Pinnacle Mines conducted an exploration program that included, trenching, diamond drilling, geochemical sampling, trail building and soil sampling. A total of 8041.61 meters of NQ, BTW and ATW size core was drilled in 67 separate drill holes with most of the drilling focused in the Silver Butte area with minor drilling testing targets in 4 other areas. A total of 750 meters of trenching were carried out in 47 trenches. Two trenches were excavated with the following assay results at Noname Lake.

In 2006, Pinnacle Mines conducted a total of 500 meters of trenching in 15 trenches using an excavator in order to obtain bedrock samples for assaying. A total of 24,151.3 meters of NQ and BTW size core was drilled in 115 separate drill holes with most of the drilling focused in one main area with minor drilling testing targets in 2 other areas. The main zone tested was the Main Breccia zone on the Kansas and Big Missouri claims with minor drilling testing the area of Dan zone on the Dan Fraction claim and Dauntless Hill zone on the Indi 9 claim. Some soil and rock sampling were also completed.

In 2010, Jayden Resources (formerly Pinnacle Mines) completed 2,808 metres of drilling in 18 NQ-sized core surface drill holes in order to expand and infill the known resources. Four drill holes were drilled on the Kansas Crown Grant, ten drill holes were drilled on the Big Missouri (405872), one drill hole was drilled on each of the Silver Coin 9 (406223) and Dan Fraction (404872), and two drill holes were drilled on the Packers (405874) mineral tenure for a total of 18 drill holes. The drilling program targeted potential mineralization along strike and improved the definition of high-grade zones within the Main Breccia zone.
