NEVADA KING BEGINS DRILLING NEWLY DISCOVERED MULTI-KILOMETER VEIN CORRIDOR AT "WESTERN RIM" TARGET

VANCOUVER, BC, Oct. 21, 2025 /PRNewswire/ - Nevada King Gold Corp. (TSXV: NKG) (OTCQB: NKGFF) ("Nevada King" or the "Company") has initiated drilling at the Western Rim Target, a large and newly defined multidirectional vein corridor that follows a district scale normal fault and associated subsidiary quartz veins along the western rim of the Atlanta caldera. Despite measuring a large 2.5km x 1.5km area, the Western Rim remains undrilled, until now. The Western Rim is located within the Company's 13,000 hectare (130km²), 100% owned Atlanta Gold Mine Project, located in the prolific Battle Mountain Trend 264km northeast of Las Vegas, Nevada. Drilling is ongoing, with 25,000m of the 30,000m planned Phase III regional drill program now complete. 

Western Rim Highlights:

• Recent groundwork completed by the Bureau of Land Management in 2023, consisting of bulldozing with large chain arrays to clear trees and vegetation, has led to the discovery of large angular blocks of sub-cropping altered tuff and exposed bedrock at the Western Rim. These large blocks of variably argillized-limonitized-hematized welded rhyodacite and dacite tuff contain a variety of quartz-limonite-hematite veins hosting Au-Ag-As-Mo mineralization that have now been mapped over a 2.5km north-northeast strike length. 
  
  
• Numerous rock chip samples have been assayed throughout the target area showing gold mineralization with gold grades up to 20.8 g/t from NNE and NW trending hematitic quartz veins surrounding a high-temperature ammonia-illite altered rhyolitic dome complex with the strongest As-Mo-Pb-Zn-Cu geochemical signatures on the property, both evidence for a strong hydrothermal system with a magmatic driver.
  
  
• The mapped quartz vein zone hosts gold mineralization that is more consistent compared to the rest of the Atlanta district, with some individual veins traced over a kilometer. In aggregate, the Western Rim shows a multi-kilometer north-northeast trending corridor of multidirectional veins exhibiting strong epithermal-type alteration and vein structures.
  
  
• High-crystallinity illite in exposed rhyolitic host rocks similar to gold hosts at the past producing Silver Park mine and the Atlanta Resource Zone ("ARZ") indicate low-temperature hydrothermal alteration commonly associated with epithermal gold systems like the caldera-hosted, world-class Round Mountain Mine. Referring to Figure 1, the illite crystallinity footprint is significantly larger than those identified at the ARZ or Silver Park and indicates the potential for a much larger system compared to those areas.

Cal Herron, Exploration Manager of Nevada King stated, "The geological, geochemical, and geophysical signature at the Western Rim point to a highly prospective region that covers a much broader footprint compared to the ARZ. It is particularly attractive given the close association of altered, rhyolitic intrusions with strongly anomalous Au-Ag-As-Mo mineralization. The Company's mapping and sampling in and around this recently exposed area has revealed a consistent pattern of NNE and NW-trending quartz veins hosting mineralization that is also more consistent and persistent compared to the rest of the Atlanta district.       

"While exploration at the Western Rim is still at an early stage, the target exhibits all the hallmarks of a large, potentially significant gold system. The combination of alteration type, robust multi-element geochemistry, and strong multidirectional fault/vein patterns are indicative of favourable structural preparation – a key component of the Atlanta Resource as well as large epithermal gold systems across Nevada. 

"Ongoing Phase III drilling at Western Rim will pursue Au-Ag mineralization both within the volcanic-hosted quartz vein zones as well as along the Tertiary-Paleozoic unconformity, similar to the Company's Phase I and II drill programs within the ARZ.  We're very excited to begin drilling this target, as it represents one of the most compelling opportunities to expand the known gold potential within the greater Atlanta district."

The 2.5km north-south by 1.5km east-west Western Rim target encompasses the SW corner of the 5km² Western Knolls area and extends further south and west, establishing the Western Rim as the largest and one of the most prospective targets on the property. The Western Knolls intrusive center, located just to the NE of the Western Rim, was the featured exploration target for the previous operator, attracted to the scale of the target area, the proximity to the caldera margin, the favourable gold host rock present, and geochemical results showing a strong presence of tracer elements for gold. They conducted surface sampling and geophysical surveys across the entire Western Knolls and ultimately drilled two reverse circulation ("RC") holes to the NE of the Western Rim, both of which encountered anomalous Au mineralization within the volcanic sequence, but adverse market conditions terminated any further exploration.

Nevada King initiated its exploration of the Western Knolls region in 2024 with geologic mapping and rock sampling together with a westward extension of the existing CSAMT coverage. Surface mapping and sampling accelerated in mid-2025, augmented by high resolution spectral imaging that was able to pick up crystalline illite and kaolinite clay signatures within covered areas immediately south and west of the Western Knolls. Starting in well-exposed outcrops south of Western Knolls, rock sampling moved progressively outward into covered areas where alteration and quartz vein blocks could be readily tracked through a thin colluvial and alluvial mantle. The ensuing vein trends led westward into the chained areas recently cleared of trees and other vegetative and soil cover by the BLM. It was here in the Western Rim target area that quartz veins were found to host Au-Ag-As-Mo mineralization that was significantly stronger than anywhere else within the Atlanta District, prompting the Company to commence drilling.

Modern Hyperspectral Technology Driving Discovery at Atlanta

Nevada King is now applying the latest airborne hyperspectral scanning and handheld spectrometer analysis available to accelerate exploration at the Atlanta Gold Mine Project. These technologies are providing a new layer of insight into mineral systems across the district and are directly guiding drill targeting.

Airborne hyperspectral surveys flown over the property measure infrared responses from alteration minerals linked to gold systems. At Atlanta, this work has highlighted multi-kilometer scale illite anomalies, as well as zones of muscovite and kaolinite that point to mineralizing fluid pathways. These datasets reveal patterns and small 'windows' through cover that can often be missed by traditional geological mapping and have outlined a new prospective corridor at the underexplored Western Rim. Key minerals identified, primarily high-crystallinity illite and ammonia-illite, consistently correlate with gold-silver mineralization elsewhere on the property, particularly at the ARZ and Silver Park, both sites of past producing mines (see Figure 1).

New handheld spectrometers are now being used to scan RC chips from Phase II resource drilling and ongoing Phase III regional exploration. Comparing these results with metals zonation within the resource has enabled near real time targeting, confirming and refining the airborne results.

Together, airborne and handheld scanning allow Nevada King to quickly map where hydrothermal fluids altered the host rocks, pinpointing the most prospective areas under thin cover. This modern toolkit is central to advancing new discovery opportunities such as the Western Rim target, where the Company is currently focusing its drilling effort.

Phase III Drilling Update

The Phase III exploration program has now surpassed 25,000m of the 30,000m planned drill program. The purpose of the program is to identify potential satellite targets or extensions of the resource area. In addition to previously released drill results from Silver Park, Atlanta South, and Atlanta North, which have all encountered above cut-off grade mineralization, the company is now drilling the fourth priority target area at the Western Rim. The Company continues to wait for additional assays from Silver Park, Atlanta South, and Atlanta North.
