Nevada King Gold Corp. (TSX-V: NKG) (OTCQX: NKGFF) is pleased to announce assay results from six reverse circulation holes and one core hole recently completed at its Atlanta Gold Mine Project located 264km northeast of Las Vegas, Nevada, in the prolific Battle Mountain Trend. These holes plotted along Section 22-7N were drilled across the high-grade feeder zone associated with several strands of a braided network of structures comprising the Atlanta Mine Fault Zone.

Cal Herron, Exploration Manager of Nevada King. stated, “The four southern-most drill sections (Sections 22-5N, 6N, 7N, and 8N) across the AMFZ show strong correlation of geology and mineralization between the sections, allowing further refinement to our geologic model for the gold and silver mineralization at Atlanta, (see Geologic Model Discussion section below). A primary focus of the 2023 drilling program is defining and following structures responsible for localizing higher-grades. As we’ve already seen, this requires closely spaced holes in order to tie together the fault blocks and wedges hosting high grades along the AMFZ. Nevada King’s new geologic model now gives us a “blue print” for targeting higher-grade Au-Ag mineralization to add to the Atlanta resource model. To this end, one rig is currently engaged in definition drilling along the AMFZ and a second drill will soon be added. At the same time, defining the thick mineralization seen west of the West Atlanta Fault provides significant blue sky potential at Atlanta, where mineralization remains open to depth and to the west. As such, the Company has dedicated one drill for this area in order to vectorize the mineralization and expedite our evaluation process.”

Table 3: Previously reported and historic holes used in Section 22-8N. AT21 series hole was drilled by Nevada King in 2021. The KR97 series holes were drilled by Kinross in 1997, the AC series hole was drilled by Goldfields in 1990, and the 88 series holes were drilled by Bobcat in 1988. Due to the multiple orientations of gold mineralization interpreted in today’s release, the Company has not yet estimated true widths for individual intercepts. *Denotes core hole. | ||||||
Geologic Model Discussion
The northerly trending, 100m to 150m wide AMFZ is the dominant structural control over higher-grade mineralization at Atlanta. It focused shallow intrusive activity and the associated hydrothermal system responsible for Au-Ag mineralization. The AMFZ is actually a narrow, up-thrown horst block of Eureka Quartzite and overlying Ely Springs Dolomite that is bounded on the east by the Atlanta King and East Atlanta Faults, and on the west by the West Atlanta Fault and its subsidiary fractures. Gold mineralization preferentially occurs within the Ely Springs Dolomite, whereas the underlying Eureka Quartzite is generally barren. Much of the dolomite in the horst block was stripped off by erosion when the block was uplifted, so the mineralization on top of the quartzite is thin and lower grade. In contrast, thicker and higher grade mineralization was focused in thick sections of down-dropped dolomite within the adjacent graben blocks on both sides of the horst. Normal faults separating these major blocks served as conduits for magma and mineralizing fluids that invaded adjacent dolomite, thereby creating extensive decalcification, collapse brecciation, and subsequent Au-Ag mineralization. Narrow, confined fault wedges adjacent to the major normal faults are altered more strongly and host the highest grades, as seen in drill holes AT22NS-73 and AT22NS-54.
Mineralization west of the West Atlanta Fault occurs within a gently west-dipping sequence of caldera-related volcanics on top of silica breccia and Ely Springs Dolomite. The silica breccia and dolomite are underlain by Eureka Quartzite that is usually barren of mineralization. As seen in Figure 2, faults displacing the basement sequence focus mineralization and strong oxidation. Mineralization within the silica breccia horizon tends to be higher grade and oxidized whereas mineralization in the overlying volcanic sequence is generally low grade (0.2-0.5 g/t Au). Oxidation in the mineralized volcanics appears to be a function of proximity to faults. Historical drill hole density in this area is low, and many of the holes did not penetrate the volcanic cover or go through the silica breccia horizon. We, therefore, have a large, sparsely-tested area to explore all along the western side of the West Atlanta Fault where we are finding a 100m thick, near-horizontal zone of gold mineralization that remains open to the west and to depth.

About Nevada King Gold Corp.
Nevada King is the third largest mineral claim holder in the State of Nevada, behind Nevada Gold Mines (Barrick/Newmont) and Kinross Gold. Starting in 2016 the Company has staked large project areas hosting significant historical exploration work along the Battle Mountain trend located close to current or former producing gold mines. These project areas were initially targeted based on their potential for hosting multi-million-ounce gold deposits and were subsequently staked following a detailed geological evaluation. District-scale projects in Nevada King’s portfolio include (1) the 100% owned Atlanta Mine, located 100km southeast of Ely, (2) the Lewis and Horse Mountain-Mill Creek projects, both located between Nevada Gold Mines’ large Phoenix and Pipeline mines, and (3) the Iron Point project, located 35km east of Winnemucca, Nevada.
The Company is well funded with cash of approximately $9.3 million as of February 2023.
The Atlanta Mine is a historical gold-silver producer with a NI 43-101 compliant pit-constrained resource of 460,000 oz Au in the measured and indicated category (11.0M tonnes at 1.3 g/t) plus an inferred resource of 142,000 oz Au (5.3M tonnes at 0.83 g/t). See the NI 43-101 Technical Report on Resources titled “Atlanta Property, Lincoln County, NV” with an effective date of October 6, 2020, and a report date of December 22, 2020, as prepared by Gustavson Associates and filed under the Company’s profile on SEDAR (www.sedar.com).

Figure 2. Cross section 22-7N looking north across the southern portion of the Atlanta Mine Fault Zone. Shallow intrusive activity and closely associated gold mineralization are localized within the volcanic and sedimentary sequence along the western side of the West Altanta Fault. Higher grade mineralization is concentrated within narrow fault blocks formed between the East Atlanta and Atlanta King Faults and along the West Atlanta Fault. (CNW Group/Nevada King Gold Corp.)
