The Sandy Gold Project (“Sandy”), located in Lyon County, Nevada, USA, shows widespread alteration and mineralization hosted by Tertiary volcanic rocks. Alteration mostly occurs as argillization of the host volcanic units, closely associated with iron oxides. Mineralization is most obviously expressed as several types of veins, including banded epithermal veins with chalcedonic to finely crystalline quartz, with varying amounts of calcite and adularia, and local barite. Coarse-grained calcite veins are also present.
“Sandy exhibits alteration, mineralization, and geochemical signatures consistent with other low-to-intermediate-sulfidation deposits in the vicinity, including Como, Hercules, and the Comstock Lode,” states Management NV Gold. “Como was in gold and silver production from 1900-1940, Hercules includes a current gold resource, and the Comstock Lode highlights the potential of this area in the Walker Lane structural province, with historic production of 8.4 Moz Au and over 190 Moz Ag.”
Sandy was originally explored in 1993-1994, which included geologic mapping, rock-chip and soil sampling, and drilling. Rock-chip assay and geochemistry values of 1.5 ppm Au, 7937 ppm As, 240 ppm Sb, and 31 ppm Hg. Seventeen (17) holes were drilled, where the strongest values were identified to be found in the altered zones and in vein systems. Historical drill intercepts found in preliminary reports are:
Sandy-6: 0.84 g/t Au from 45.7m to 57.9m, 1.16 g/t Au from 106.7m to 115.8m, 0.53 g/t Au from 131.1m to 140.2;
Sandy-7: 0.91 g/t Au from 48.8m to 54.9m; and
Sandy-10: 0.44 g/t Au from 48.8m to 54.9m.
“These types of deposits are ideal for structural targeting, and we look forward to initiating our own mapping and sampling campaign this fall,” continues Management, NV Gold. “We are currently planning on building a better understanding of mineral deposits for the Sandy vicinity, and will look to assess additional information from our databases regarding the project and local area.”
NV Gold notes that there is no guarantee that the historical results are representative and cannot guarantee that the Company will be able to duplicate the results with future exploration programs.
Review of the Expanded 2021 Drill Phase I Program at the Sandy Gold Project
As previously stated in the news release dated February 9th, 2021, the Company believes that drilling has encountered a large epithermal gold system defined by extensive argillic to propylitic alteration with intervals of moderate to intense quartz and pyrite veining (Figure 1). Some of the quartz vein intercepts from the current drill program have measured up to 30 m (100 ft) wide. Quartz vein cuttings often display multi-phase brecciation, a sign of boiling in the system, a good indicator for potential high-grade mineralization. Most of NV Gold’s drill holes have far exceeded the depth of historical drilling conducted in 1993.
Based on the expanded drill program, the newly identified mineralized vein system now has a strike length of at least 2.4-kilometer (1.5 miles) and is hosted by a thick andesite volcanic package. Some of the underlying shaly basement rocks continued to show visual evidence of veining and alteration. Most of the property remains undrilled, and the system remains open at depth and in adjacent areas under late volcanic cover.
