NEVADA KING REPORTS POSITIVE PHASE 2 METALLURGICAL TEST RESULTS AT ATLANTA CONFIRMING CONVENTIONAL OXIDE PROCESSING WITH A SIMPLIFIED FLOWSHEET

Rhea-AI Summary

Nevada King Gold (OTCQB: NKGFF) reported positive Phase 2 metallurgical test results from its Atlanta Gold Mine Project, confirming conventional oxide processing with a simplified flowsheet. The comprehensive testing program, which included 26 drill core composites in Phase 2 and 22 composites in Phase 1, demonstrated strong gold recoveries across key mineralized units.

Fine milling showed weighted average gold extractions of 90.1% for non-silicified volcanics, 86.1% for silicified volcanics, and 87.7% for silica breccia. Column leaching of crushed material achieved 83.1% extraction for non-silicified volcanics. The revised flowsheet simplifies operations by replacing three-stage crushing with primary and secondary crushers and eliminating convey-stack processing.

Positive

• Strong gold recoveries across all key mineralized units with up to 90.1% extraction using fine milling
• Simplified flowsheet expected to reduce operating and initial capital costs
• Non-silicified volcanics showed excellent heap leach recovery of 83.1%

VANCOUVER, BC, July 16, 2025 /PRNewswire/ - Nevada King Gold Corp. (TSXV: NKG) (OTCQB: NKGFF) ("Nevada King" or the "Company") is pleased to report results from its Phase 2 metallurgical testing program at its 12,000 hectare (120km²), 100% owned Atlanta Gold Mine Project, located in the prolific Battle Mountain Trend 264km northeast of Las Vegas, Nevada. Phase 2 results confirm and expand on the Phase 1 results (released March 26, 2024), while delivering a more simplified flowsheet with potential for lower operating and initial capital costs, and continuing to demonstrate that gold and silver mineralization at Atlanta is well suited to conventional oxide processing methods widely used in Nevada.

Highlights:

• Robust Recoveries: Combined, Phase 1 and 2 test work consistently demonstrated strong gold recoveries across key mineralized units using both fine milling and heap leaching methods. 
  
  
  • Fine milling (200-mesh grind, P80 = 75 µm) shows a weighted average gold extraction of 90.1% for the non-silicified volcanics, 86.1% for the silicified volcanics, and 87.7% for the silica breccia (SBX).
    
    
  • Column leaching of conventional crushed (combined P80 = 12.5 & 25.0 mm columns) shows a weighted average extraction of 83.1% for the non-silicified volcanics (heap leachable).
    
    
• Dual Recovery Pathways: Results continue to support a development path utilizing conventional milling for higher-grade material, while lower-grade, non-silicified volcanics are suitable for run of mine ("ROM") heap leaching.
  
  
• Simplified Flowsheet: The revised proposed flowsheet has been simplified and is expected to result in lower operating and initial capital costs by replacing three-stage crushing with a primary and secondary crusher and eliminating the convey-stack process. Additionally, while the prior flowsheet envisioned two separate heap leach processes, the new simplified flowsheet includes just one, consisting exclusively of ROM material.
  
  
• Comprehensive Test Program: Phase 2 tested 26 drill core composites, adding to the 22 drill core composites and three bulk samples tested in Phase 1, which together provide a comprehensive dataset of the various lithologies and grade ranges found throughout the Atlanta resource.

Phase 2 metallurgical test work at Atlanta has been supervised by Gary Simmons (MMSA QP Number: 01013QP), formerly the Director of Metallurgy and Technology for Newmont Mining Corp. Mr. Simmons also supervised the Phase 1 metallurgical test work at Atlanta and has managed numerous metallurgical testing programs in the Great Basin with characteristics similar to those found at Atlanta.

Mr. Simmons commented, "The Phase 2 results refine the findings from Phase 1, that conventional oxide milling of the silicified volcanics, SBX and dolomite material types will be suitable to process the Atlanta mineralization. The non-silicified volcanics are amenable to conventional ROM heap leaching.

"The inclusion of HPGR will provide a relatively lower overall operating cost for SBX compared to alternatives such as a SAG/Ball mill processing. The Phase 2 testing provided additional clarity on the metallurgical characteristics of a wider variety of rock type subunits included in the resource area and is another step in de-risking the Atlanta Gold Mine project."

Test Results Summary:

The Atlanta resource is generally categorized into two distinct categories for the purposes of metallurgical testing of gold and silver extraction. There is the SBX (mineralized material in and below the main Atlanta unconformity) and the volcanics (mineralized material above the main Atlanta unconformity). Of the 26 composites tested in Phase 2, 17 were within or below the unconformity representing SBX material and nine were within the volcanics. A higher ratio of samples of SBX material was used in Phase 2,compared to nearly equal samples from SBX and volcanics in Phase 1, to improve the understanding of the SBX material and the metallurgical characteristics of the subunits.

MATERIAL	GOLD EXTRACTION – MILLING (P80=75ΜM)	GOLD EXTRACTION – HEAP LEACH (P80=12.5–25MM)	SILVER EXTRACTION – MILLING (P80=75ΜM)
VOLCANICS (NON-SILICIFIED)	90.1% (2.71 g/t Au)	83.1% (2.56 g/t Au)	58.1% (25.0 g/t Ag)
SILICIFIED VOLCANICS	86.1% (2.80g/t Au)	55.9% (2.83g/t Au) – Not suitable for heap leach	28.2% (7.4 g/t Ag)
SILICA BRECCIA (SBX)	87.7% (3.23 g/t Au)	Not Applicable	43.9% (26.0 g/t Ag)
DOLOMITE	80.6% (0.32 g/t Au)	52.0% (0.30 g/t Au)	23.3% (23.2 g/t Ag)

Table 1. Summary Phase 1 and 2 Atlanta laboratory gold extraction results, average gold bottle roll & column leach tests with average gold and silver grade.

Phase 2 metallurgical test work emphasized testing SBX material, located below or in the unconformity, due to the hard and abrasive nature which has a high degree of sensitivity to process feed particle size. This material can be processed utilizing High Pressure Grinding Rolls ("HPGR") comminution followed by fine milling.

The non-silicified volcanics sit above the unconformity and typically show higher recoveries and less sensitivity to particle size for processing. The volcanics are amenable to processing via conventional milling, or ROM heap leaching, with the grade and future economic analysis being the primary determinant on processing method.

Gold extraction at a typical fine grind of 75 µm remained strong for all material types through Phase 2 results, reinforcing the amenability to conventional cyanidation.

HPGR comminution of SBX material, followed by column leaching, shows that this material is not suitable for heap leaching, due to its lower gold extraction versus testing in Phase 1. This material showed a weighted average gold extraction of 56.1% at 3.66 g/t Au.

Overall, Phase 2 closely mirrors Phase 1 in grade, extraction behavior, and composition and validates the Phase 1 results, with high cyanide solubility across both phases. Phase 2 also confirmed negligible preg-robbing, so it remains a non-issue after both phases. Fine grinding remains very effective across all lithologies.

Phase 1 and 2 combined gold extraction from fine milling at a 200 mesh grind (P80=75µm) show a weighted average gold extraction of:

• 90.1% for the non-silicified volcanics at an average head grade of 2.71 g/t Au
  
  
• 86.1% for the silicified volcanics at an average head grade of 2.80 g/t Au
  
  
• 87.7% for the SBX at an average head grade of 3.23 g/t Au
  
  
• 80.6% for the dolomite at average head grade 0.32 g/t Au

Phase 1 and 2 combined gold extraction from conventional crushing (P80=12.5 + 25.0 mm columns) show a weighted average gold extraction of:

• 83.1% for non-silicified volcanics (to be processed via heap leach) at an average head grade of 2.56 g/t Au
  
  
• 55.9% for silicified volcanics at an average head grade 2.83 g/t Au (to be processed via milling)
  
  
• 52.0% for the dolomite at an average head grade of 0.30 g/t Au
  
  
• SBX materials are not suitable for heap leaching due to the low weighted average gold extraction

Phase 1 and 2 combined silver extraction from fine milling at a 200 mesh grind (P80=75µm) show a weighted average silver extraction of:

• 58.1% for non-silicified volcanics at an average head grade of 25.0 g/t Ag
  
  
• 28.2% for silicified volcanics at an average head grade of 7.4 g/t Ag
  
  
• 43.9% for SBX at an average head grade of 26.0 g/t Ag
  
  
• 23.3% for dolomite at an average head grade of 23.2 g/t Ag

Table 1 below provides a summary of laboratory metallurgy gold extraction test results from both Phase 1 and Phase 2 and distinguishes between the materials tested above and below the Atlanta unconformity indicating whether the mineralization is in volcanics or silicified breccias, while Table 2 does the same for silver.

QA/QC Protocols

All PQ-diameter core was sampled in the Company's warehouse in Winnemucca, Nevada, with whole core samples being placed in heavy canvas bags and sent to American Assay Lab in Reno, Nevada, in heavy shipping bags by a Company contractor with full custody being maintained at all times. CRF standards and coarse blanks were inserted into the sample stream on a one-in-twenty sample basis, meaning both inserts are included in each 20-sample group. At American Assay Lab, samples were weighted, and then completely crushed to -1 inch. The coarse-crushed sample was quarter-split and one quarter was reduced to 75% passing 2mm. A 300g split was subsequently pulverized to 85% passing 75 microns. 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. The QA/QC procedure involves regular submission of Certified Analytical Standards and property-specific duplicates.

FAQ

What were the key findings from Nevada King Gold's Phase 2 metallurgical testing at Atlanta?

The testing confirmed strong gold recoveries with 90.1% extraction for non-silicified volcanics, 86.1% for silicified volcanics, and 87.7% for silica breccia using fine milling methods.

How will NKGFF's simplified flowsheet affect operations at the Atlanta Gold Mine?

The simplified flowsheet replaces three-stage crushing with primary and secondary crushers, eliminates convey-stack processing, and consolidates to a single ROM heap leach process, expected to reduce operating and initial capital costs.

What are the gold recovery methods proposed for the Atlanta Gold Mine project?

The project will use two recovery methods: conventional milling for higher-grade material and ROM heap leaching for lower-grade, non-silicified volcanics.

What were the silver extraction rates in Nevada King's Atlanta project testing?

Silver extraction rates varied by material type: 58.1% for non-silicified volcanics, 28.2% for silicified volcanics, 43.9% for SBX, and 23.3% for dolomite.

How many samples were tested in NKGFF's metallurgical program?

The comprehensive program tested 26 drill core composites in Phase 2, adding to 22 drill core composites and three bulk samples from Phase 1, covering various lithologies and grade ranges.
