NEVADA KING STRIKES BONANZA OXIDE GOLD WITH 11.64 G/T AU OVER 108.3M, INCLUDING 37.16 G/T AU OVER 29M AT ATLANTA

Nevada King Gold Corp. has released assay results from three vertical reverse circulation (RC) holes recently completed at its Atlanta gold mine project, located 264 kilometres northeast of Las Vegas, Nev., in the prolific Battle Mountain trend. These holes were drilled northwest of the Atlanta pit to fill in drill hole gaps across the northern part of the West Atlanta graben zone (WAGZ) identifed in Section 22-15N initially reported on April 27, 2023.

Highlights:

  • AT23WS-44 (which returned 11.64 grams per tonne gold over 108.2 metres, including 37.16 grams per tonne gold over 29.0 metres) is the most gold-rich drill hole ever recorded at Atlanta and contains the highest-grade individual drill assay interval ever reported from the project of 169.8 grams per tonne gold over 1.5 metres (see an attached table for a detailed breakdown of the full 29-metre high-grade interval and an attached table for the complete detailed breakdown of the 108.2-metre intercept).
  • AT23WS-44 was sited 120 metres northwest of the Atlanta pit to locate and test the West Atlanta fault No. 1 (WAF1) and was collared 20 metres west of previously reported AT22WS-5C (1.08 grams per tonne gold over 112.7 metres) and 22 metres east of previously reported AT23WS-20 (3.04 grams per tonne gold over 61.1 metres).
  • The company's new geological model supports the presence of very high-grade zones, or jewellery boxes, that can occur at the juncture between subvertical feeder zones and flat-lying horizons of replacement-type (Carlin-type) mineralization.
  • AT23WS-44 is interpreted to have penetrated the mineralized zone near the middle of a high-grade zone close to and possibly intersecting the WAF1. AT23WS-20 intersected the western portion of the more-than-three-gram-per-tonne-gold high-grade zone while AT23WS-5C on the east narrowly missed the high-grade domain.
  • Now, with WAF1 firmly located, the company is planning to follow up on AT23WS-44 with closely spaced vertical holes east and west to better determine the lateral extent and grade distribution in and around the feeder structure while also following it along strike, where it remains open to the north and south.
  • Mineralization in this high-grade interval is strongly oxidized as demonstrated by the gold cyanide solubility analyses in an attached table. Visible gold has not been observed in the cuttings. The absence or paucity of coarse-grained gold is supported by the consistent results from duplicate fire assays of all high-grade intervals (see an attached table).

Cal Herron, exploration manager of Nevada King, stated: "Today's high-grade interval in AT23WS-44 gives us another starting point for tracking higher grades proximal to high-angle feeder structures cutting up through the flat-lying horizons that correlate to stratigraphy hosting most of the gold at Atlanta -- namely the silica breccia and overlying silicified volcanic horizons. [...] The rhyolitic intrusive breccia hosting the highest-grade mineralization in the hole probably intruded along the WAF1 and will be easy to visually track in the upcoming offset holes of AT23WS-44 that will be drilled to further expand upon this bonanza-grade mineralization. It is important to note that the high-grade core mineralization seen in AT23WS-44 (29 metres of 37.16 grams per tonne gold) is not related to a narrow vein that was drilled down but rather occurs within the same flat-lying replacement horizon penetrated in surrounding holes at similar elevation -- i.e., 1,741 metres (1,770 metres ASL (above sea level)). For example, nearby holes in the northern portion of the WAGZ intersected the following high-grade mineralization:

  • AT23WS-20, located 20 metres west of AT23WS-44, returned 27.6 metres of 4.67 grams per tonne gold from 1,730 metres to 1,758 metres above sea level.
  • AT23WS-22, located 68 metres west of AT23WS-44, returned 7.6 metres of 28.5 grams per tonne gold from 1,743 metres to 1,750 metres above sea level.
  • AT22WS-2, located 41 metres north of AT23WS-44, returned 33.6 metres of 4.10 grams per tonne gold from 1,746 metres to 1,780 metres above sea level.
  • AT23WS-23, located 63 metres northwest of AT23WS-44, returned 12.2 metres of 8.78 grams per tonne gold from 1,745 metres to 1,757 metres above sea level.

Elsewhere within the Atlanta resource zone, the company sees very similar elevation control over high-grade mineralization. Examples near the East Atlanta fault within the AMFZ include:

  • AT21-62 returned 10.7 metres of 11.19 grams per tonne gold from 1942m-1953m above sea level
  • AT23NS-116 returned 4.6 metres of 7.31 grams per tonne gold from 1937m-1942m above sea level
  • AT22NS-81T returned 5.3 metres of 10.73 grams per tonne gold from 1925m-1931m above sea level

The same pattern is apparent across the southern portion of the WAGZ -

  • AT22-8T returned 13.4 metres of 7.65 grams per tonne gold from 1879m-1893m above sea level
  • AT22SE-42 returned 13.7 metres of 4.05 g/t from 1864m-1888m above sea level
  • AT23HG-28 returned 12.2 metres of 7.59 grams per tonne gold from 1841m-1854m above sea level
  • AT23HG-34 returned 27.4 metres of 4.50 grams per tonne gold from 1841m-1870m above sea level
  • AT22HG-13 returned 12.2 metres of 17.59 grams per tonne gold from 1875m-1887m above sea level

The high grade intercepts cited above occur within discrete groups or clusters located across the entire resource zone, with holes in each cluster sharing the same elevation ranges. This argues strongly for the high-grades being hosted within near-horizontal replacement horizons versus narrow, high-angle faults/veins. If these intercepts occurred along high-angle fault surfaces, we would not see a uniform horizontal geometry, instead the intercept elevations within an individual cluster of holes proximal to each other would indicate a steeply dipping plane. Close-spaced drilling along suspected high-grade zones has now provided Nevada King with enough information to concentrate on drill-defining these relatively narrow (span class="xn-money">20m wide) but very high-grade, linear intersection zones involving high-angle "feeder" faults and flat-lying replacement horizons."

Additional Details

  • Holes AT23WS-25A (24.4m grading 1.19 grams per tonne gold from 318.6 to 343.0m) and AT23WS-41 (22.9m grading 0.293 grams per tonne gold from 335.4 to 358.2m) were drilled west of previously reported hole AT23WS-22 (42.8 metres of 5.64 grams per tonne gold) in order to define the western boundary of the WAGZ. Both of these new holes hit deeper, lower grade mineralization on the west side of the West Atlanta Fault #2 (WAF2), which bounds the western margin of the WAGZ. Gold grade in this area clearly decreases westward from the WAF2.
  • The high grade intercept in previously reported hole AT23WS-22 (42.8 metres of 5.64 grams per tonne gold) is attributed to close proximity to the WAF2. Now that we know where this fault is located, we will be drilling along strike of it to the north and south in order to further extend the higher-grade mineralization.
  • Additional in-fill drilling is needed between AT23WS-5C and AT23NS-104 in order to fill a large 88m gap that currently exists between AT23WS-5C and the West Atlanta Fault (see Figure 3).

Detailed Interpretation:

The Company's interpretation of today's highlight interval is that gold mineralizing fluids have migrated laterally from the high-angle WAF1 (the feeder structure) into a larger receptive, flat-lying breccia horizon with gold grades generally decreasing gradationally with horizontal distance from the feeder structure (Figure 1). The Company does not have sufficient data to accurately estimate true width of the high grade feeder structure, but true thickness of the high grade zones within the overall flat-lying mineralized horizon is far more apparent. As an example, simply comparing the 29m-thick high grade intercept (37.16 grams per tonne gold) in AT23WS-44 with the 27.4m high grade intercept (4.67 grams per tonne gold) in AT23WS-20 illustrates the flat-lying nature of the high grade horizon connecting these two holes. The mineralized zone in AT23WS-44 starts at an elevation of 1770m above sea level (above sea level) while the same mineralized horizon in AT23WS-20, located 21m to the west of AT23WS-44, starts at an elevation of 1758m above sea level This flat-lying geometry to the replacement horizon is noted throughout the Atlanta deposit as discussed above.

QA/QC Protocols

All Reverse Circulation (RC) samples from the Atlanta Project are taken at 1.5 m intervals, split at the drill site and placed in cloth and plastic bags utilizing a nominal 2kg sample weight. Certified Reference Material (CRM) standards, blanks, and blind duplicates are inserted into the sample stream on-site on a one-in-twenty sample basis, meaning all three control inserts are included in each 20-sample group. Samples are shipped by a local contractor in large sample shipping crates directly to American Assay Lab in Reno ("AAL"), Nevada, with full custody being maintained at all times. At AAL, samples were weighed then crushed to 75% passing 2mm and pulverized to 85% passing 75 microns in order to produce a 300g pulverized split. Prepared samples are initially run using a four acid + boric acid digestion process and conventional multi-element ICP-OES analysis. Gold assays are initially run using 30-gram samples by lead fire assay with an OES finish to a 0.003 ppm detection limit, with samples greater than 10 ppm finished gravimetrically. Every sample is also run through a cyanide leach for gold with an ICP-OES finish. For Au values above 10 g/t, AAL routinely re-assays samples using a 30gm gravimetric fire assay. For the 29m high grade interval in AT23WS-44, AAL inserted three lab duplicates that results in percent differences of 1.80%, 2.48%, and 2.59%. No visible gold was logged in this hole.

Sample weights were consistent.

Table 7 contains the complete assay report for the interval 195.1m to T.D. at 330.8m for AT23WS-44 showing sample weights as received at American Assay Lab plus lab blank, duplicate, and CRM standards along with Nevada King's inserted field blanks, duplicates, and CRM standards. The high grade intervals were assayed by 30gm fire with ICP finish and then check-assayed via 30 gm gravimetric fire assay. Gold cyanide solubility assays were performed on every sample. As seen in Table 6, the 30gm ICP analyses match closely with the gravimetric analyses, indicating minimal nugget effect and high reproducibility. The consistent Au cyanide analyses indicate strong oxidation and little evidence of significant sulfide encapsulation. Fairly consistent sample weights indicate good, overall RC recovery, particularly within the very high grade intervals, to the extent that down-hole contamination from upper high grade intervals is unlikely. When 10m to 20m lengths of low sample weights occur, or sustained lack of sample recovery occurs, then down-hole contamination is more likely to occur. This is not the case with AT23WS-44.
