The West Pinyon Target

System Type:

Low-sulfidation, volcanic hosted, epithermal gold system.

Strike-Length:

The West Pinyon target covers an area of approximately 1.1 by 2 kilometers.

Resource: 

None at this time. 

Location:

The West Pinyon target is located immediately west of the Pinyon target in the southwest corner of the Gold Springs property, on the Nevada side of the project. 

Drilling:

No drilling has been conducted at West Pinyon. 

Geophysics:

The Pinyon target area has not been covered by the ZTEM (airborne) or CSAMT (ground-based) geophysical surveys.

Geology: 

The West Pinyon target is situated along the western margin of the Gold Springs Caldera complex and displays structures related to the caldera collapse, similar to the setting at the Grey Eagle resource. Like the Pinyon target, West Pinyon is interpreted to be a high-level expression of a caldera-margin-hosted, epithermal, gold system. Mineralization is hosted in altered andesite flows. Younger rhyolite dikes cut across the target area with dominate northwest and east-west trends, some of which are altered and host stockwork quartz veining. The target covers 2.1 square kilometers that are largely covered with colluvium. However, where exposures are found, northeast, northwest and east-west trending calcite-quartz-vein zones display banded and bladed textures similar to those found at the existing resource areas on the project. The vein zones are often only traceable for 10’s of metres and appear at the margins of fault zones. These vein zones are interpreted to be fracture-fill, pod-like features resulting from faulting associated with a collapse feature.

West Pinyon is largely covered with colluvium, however windows through the cover exposes discontinuous banded-bladed calcite-quartz vein zones and more expansive areas of hydrothermal brecciation. Mineralized float, dominantly in the form of hydrothermal breccia, is found mixed in with colluvium throughout much of the area suggesting that the post-mineral cover is thin. Hydrothermal breccia zones in outcrop cover an area of approximately 800m x 400m with scattered showings throughout the 1.1 x 2 kilometre target area.

Structural Geology:

Structurally, the West Pinyon target is complex, with varying fault trends and limited surface exposure. The target hosts parallel sets of northeast trending ridges margined by fault zones of the same trend. Between bounding northeast trending fault zones, ridges are cut by a series of northwest, northeast and east-west trending faults that often host post-faulting rhyolite dikes and intermittent vein zones. Within fault blocks much of the host rock is hydrothermally brecciated, typical of collapse feature such as a caldera margin or breccia-pipe. 

Historical Mining: 

Historical workings are scattered throughout the target area and consist of shallow surface workings such as trenches and pits and one collapsed adit near the center of the map area. 

Geochemistry:

Thought the area host expansive zones of hydrothermal brecciation, recent sampling shows mineralization above cut-off to be dominantly contained within vein zones grading as high as 42.30 g/t Au and 131.0 g/t silver. Values greater than the resource cut-off grade of 0.25 g/t Au are listed in the table below.
