Nevada King starts drilling Western Rim at Atlanta

Mr. Cal Herron reports NEVADA KING BEGINS DRILLING NEWLY DISCOVERED MULTI-KILOMETER VEIN CORRIDOR AT "WESTERN RIM" TARGET Nevada King Gold Corp. 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 2.5-kilometre-by-1.5-kilometre area, the Western Rim remains undrilled, until now. The Western Rim is located within the company's 13,000-hectare (130-square-kilometre), 100-per-cent-owned Atlanta gold mine project, located in the prolific Battle Mountain trend 264 km northeast of Las Vegas, Nev. Drilling is continuing, with 25,000 m of the 30,000 m 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 subcropping 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 (gold-silver-arsenic-molybdenum) mineralization that have now been mapped over a 2.5 km 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 grams per tonne from NNE-(north-northeast)- and NW-(northwest)-trending hematitic quartz veins surrounding a high-temperature ammonia-illite altered rhyolitic dome complex with the strongest As-Mo-Pb-Zn-Cu (arsenic-molybdenum-lead-zinc-copper) 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 with the rest of the Atlanta district, with some individual veins traced over a kilometre. In aggregate, the Western Rim shows a multikilometre 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. 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 multielement 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. "Continuing 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 2.5 km north-south by 1.5 km east-west Western Rim target encompasses the southwest corner of the five square km Western Knolls area and extends farther south and west, establishing the Western Rim as the largest and one of the most prospective targets on the property. The Western Knolls intrusive centre, located just to the northeast 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 northeast 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 Bureau of Land Management. 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 multikilometre-scale illite anomalies, as well as zones of muscovite and kaolinite that point to mineralizing fluid pathways. These data sets 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. New handheld spectrometers are now being used to scan RC chips from phase II resource drilling and continuing 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 25,000 m of the 30,000 m 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.

QA/QC (quality assurance/quality control) protocols All surface rock and soil samples are shipped by a local contractor directly to American Assay Lab in Reno, Nev., with full custody being maintained at all times. At American Assay Lab, samples were weighted then crushed to 75 per cent passing two millimetres and pulverized to 85 per cent passing 75 micron to produce a 300-gram pulverized split. Prepared samples are initially run using a four-acid plus boric acid digestion process and conventional multielement ICP-OES analysis. Gold assays are initially run using 30-gram samples by lead fire assay with an OES finish to a 0.003 part per million 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.
