System Type:
Low-sulfidation, volcanic hosted, epithermal gold system.
Strike-Length:
The Pinyon target covers 2.2 square kilometers that are largely covered with colluvium and post-mineral tuffs.
Resource:
None at this time.
Location:
The Pinyon target is located in the southwest corner of the Gold Springs project, on the Nevada side of the project.
Drilling:
No drilling has been conducted at Pinyon.
Geophysics:
The Pinyon target area has not been covered by the ZTEM (airborne) or CSAMT (ground-based) geophysical surveys.
Geology:
The 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. The Pinyon target is interpreted to be a high-level expression of a caldera margin hosted, epithermal gold system.
The target covers 2.2 square kilometers that are largely covered with colluvium and post-mineral tuffs. However, where exposures are found, northeast-trending sheeted-calcite-quartz-vein zones display coarse-bladed textures similar to those found at the existing resource areas on the project. The sheeted vein zones have widths of up to 50 meters before being lost under post-mineral cover.
Structural Geology:
Structure at Pinyon is dominated by a series of northeast trending faults. Lateral movement along these features provided the ground preparation for the mineralizing fluid migration. In addition, there are a number of arcuate features within the target area which are interpreted to be related to caldera margins.
Historical Mining:
Scattered pits and cuts are located across the area.
Geochemistry:
Mineralized float is also found throughout the target area with samples of calcite-quartz and quartz vein material grading as high as 3.3 g/t Au and 6.9 g/t silver. Altered andeside host rock sampled in float returned grades of 3.69 g/t Au and 16.1 g/t silver. Values greater than the resource cut-off grade of 0.25 g/t Au are listed in the table below.
