The Sandy project comprises 54 unpatented mining claims, located in Lincoln County, Nevada. The claims cover a section of Cambrian limestone and shale, overlain by Tertiary volcanic rocks. Jasperoid is developed in several locations along north-northwest trending faults and as tabular masses concordant with the east dipping limestone / shale contact.
Sandy is a sediment-hosted, “Carlin-type” gold target, and as such is a true, “off-trend” exploration play. Limited historic work by Exxon, Prochnau, Bow Valley and others identified areas with anomalous gold in outcrop and produced narrow drill intersections of gold-bearing jasperoid at three locations.
Further target generation work is deemed warranted and will be undertaken in 2017.
Location and Land Tenure
The Sandy property is located at the north end of the Groom Range in Lincoln County, Nevada, about nine kilometers southeast of Rachel. The project is easily accessible from Rachel via paved highway and two-track ranch roads. It comprises 54 unpatented lode mining claims, under BLM jurisdiction
Geology and Alteration
Bedrock comprises a sequence of SE dipping limestone, dolomite, and shale unconformably overlain by Tertiary volcanic rocks and alluvial sediment.
Gold bearing jasperoid occurs along the contact between the Cambrian Lincoln Park/Candland limestone and the overlying Dunderburg shale. This is the same stratigraphic interval which is mineralized at Pilot Gold’s Kinsley Mountain project.
Jasperoid occurs at four distinct locations over 800 x 3,000 m, and appears to extend under younger cover rocks to the north and east. Drill holes completed into the Pediment, West Jasperoid, and South Jasperoid areas all intersected gold-bearing silicified limestone. Very shallow drill holes at North Jasperoid were unsuccessful, but IP chargeability anomalies on the target have never been tested.
There has been relatively limited historic work completed on the claims, and very little surviving paper data to document programs and results. The current claim block was first staked by Exxon Minerals in 1984 who conducted rock chip sampling, soil sampling, and a geophysical survey; this culminated in a number of shallow RC holes. Subsequent work was conducted by Prochnau, Bow Valley, and the WX syndicate.
A small mercury resource occurs in volcanic rocks approximately 1.5 kilometers south of the claim block.
The widespread jasperoid occurrences at Sandy have been only partially tested by shallow historic drilling and Logan deems the project worthy of further exploration. A program of work and budget will be developed in 2017 to include comprehensive geologic mapping, soil sampling and CSAMT surveys.
