Snapshot

M4

M4 is primarily a copper target, with over 2 km of copper-in-soils anomalies above a similar sized charegabilty anomay. Copper showings at the prospects western end have been the focus of limited intitial drilling, the best intercept from which was 42.9 m @ 0.23% Cu from 106.22 m in a quartz-carbonate breccia zone, which may represent a breccia pipe in the upper parts of a porphyry system.

Key Facts

3 diamond holes were drilled in 2018
Large quartz-copper breccia zone intercepted from 106.2 metres
42.9 m @ 0.24% Cu, including 1.8 m @ 0.74% Cu from 121 m

Exploration

The M4 copper target was identified through geophysical surveys, soil sampling, and mapping of mineralised veins on surface. Three diamond holes were drilled in 2018 to test beneath outcrops of cupriferous vein and silicic alteration. One hole, M4_005, hit a large quartz-copper breccia vein at 106.2 metres. The intercept comprised 43.0m @ 0.24% Cu, including 1.8m @ 0.74% Cu from 121m.

Geology

The Golconda thrust fault is a major structural feature spanning the length of Nevada. The large, disseminated silver deposits that were mined at Candelaria are intimately associated with the Golconda thrust fault. The Candelaria fault extends westward into California and passes through the southern Great Western claims in the Huntoon Valley area.

The M4 prospect is hosted in altered and folded siliceous host rock striking accross the width of the Jack Springs claims, from the Huntoon Valley in the west to Jack Springs canyon where it meets Teels Marsh in the east. In some areas the host rocks are obscured by Tertiary volcanic sequences and recent sediments.

Far to the east of M4, the general west-east trend meets that of the Neo - Smith - O&K - M5 trend. This is a sequence of old workings in copper showings lying along the eastern flank of the hills in this area.
