Atlanta Gold Mine
Atlanta is a past producing,
open-pit gold mine located in SE Nevada
Historic production by Standard Slag (1975-1985) recovered 110,000 oz Au and 800,000 oz Ag from 1.5M tons.
Over 40,000m were drilled by Gold Fields, Kinross Gold and Meadow Bay Gold starting in the early 1990s.
The Project is 100% owned by Nevada King and includes a NI 43-101 Resource published in 2020.
Infrastructure & Permitting
County-maintained roads connect project to major highways.
Deeded 15-mile electrical power line is operational to the site with private substation.
Private water well and pipeline delivers ample water to project.
Modular building purchased to provide crew quarters during the exploration phase.
Old Mill Building and Crusher Complex have been removed.
2020 43-101 Resource, pit-constrained
$1250/ounce gold price

2021 Atlanta Drilling Highlights
Cross Section A-A’
Historical holes along this southern E-W cross section reported significant gold intercepts but were not included in the Gustavson resource model due to low hole density, inaccurate collar locations, and suspect assays.
In 2021, Nevada King drilled several holes to confirm and add gold mineralization in this area, which is located within the confines of Gustavson’s conceptual open pit, but was previously categorized as waste rock.
Long Section I-I’
This long section demonstrates areas of newly identified gold mineralization that were previously considered to be waste rock, within the confines of the conceptual open pit. Additionally, it shows the fence of five high-grade holes drilled from the bottom of the pit, which intercepted a thick bed of oxide gold mineralization.
2022 – Phase II Drill Program
Test new high-grade discovery within the pit, increasing drill density and connecting future high-grade mineralization.
Test northwest high-grade target.
Investigate high-grade discovery in AT21-003 with drilling 560m north of historic pit and priority targets 1.2km along strike.
Explore east ridge target to understand extent of mineralization to the east.
100 planned drill targets totaling 13,100 meters
10,000 meters of RC, including pre-collar drilling
3,100 meters of core drilling
Numerous historical holes failed to fully penetrate the higher-grade zones at depth, so 2022 drilling will also involve re-drilling these gaps within the overall resource zone, tying them to adjacent high-grade intercepts, and expanding the known high-grade mineralization into areas of low historical drill density and potentially increasing the overall resource at Atlanta.
Meters Drilled On Nevada King Properties
Stage 1 Cyanide Solubility Testing
Gold cyanide solubility demonstrated a weighted average of 86.7% across 986 samples.
Samples analysed were widely distributed, with over half coming from outside the historical Atlanta Mine open pit, extending up to 560m north of the pit (see Figure 1).
Cyanide solubility was consistently high in all holes, with 69% of the samples exceeding 80% Au cyanide solubility while only 2% of the samples returned less than 50% cyanide solubility.
Aside from gold grade, no systematic influence on cyanide solubility was observed with respect to depth, gold grade, rock type, alteration type, degree of silicification, degree of fracturing, clay content, or collar location.
Table 1. Summary of gold cyanide solubility tests on 986 drill hole intervals from Nevada King’s 2021 program.
^Due to natural variation in the distribution of gold in the samples, certain samples demonstrate higher than 100% gold solubility. In such cases, the split that was analyzed via fire assay may have fewer gold particles in it than the split that was used for the CN solubility analysis.
