NEVADA KING DEMONSTRATES AVERAGE GOLD CYANIDE SOLUBILITY OF 86.7% IN INITIAL TESTING AT ATLANTA GOLD MINE, BATTLE MOUNTAIN TREND, NEVADA

VANCOUVER, BC, July 5, 2022 /CNW/ - Nevada King Gold Corp. (TSXV: NKG) (OTCQX: NKGFF) ("Nevada King" or the "Company") is pleased to announce very positive results from its Stage 1 cyanide solubility testing program at the Company's 100% owned Atlanta Gold Mine, located 264km northeast of Las Vegas at the southern end of the Battle Mountain Trend. The project has historically returned significant gold grades but was long considered to have limited amenability to cyanide extraction. A total of 986 mineralized samples were selected from 54 RC holes covering the extent of the 2021 drilling. All samples were submitted to American Assay Lab (AAL) for cyanide solubility and ICP multi-element analyses.

Highlights

• Gold cyanide solubility demonstrated a weighted average of 86.7% across 986 samples.
• Samples analysed were widely distributed, with over half coming from outside the historical Atlanta Mine open pit, extending up to 560m north of the pit (see Figure 1).
• Cyanide solubility was consistently high in all holes, with 69% of the samples exceeding 80% Au cyanide solubility (see Table 1) while only 2% of the samples returned less than 50% cyanide solubility.
• Aside from gold grade, no systematic influence on cyanide solubility was observed with respect to depth, gold grade, rock type, alteration type, degree of silicification, degree of fracturing, clay content, or collar location. Gold solubility is slightly higher in material exceeding 1.50g/t. Samples were for the most part thoroughly oxidized and ranged in depth from the surface down to 197m.
• Designed by the Company's metallurgical consultant, Gary Simmons (announced April 12, 2022), this Stage 1 program used 986 pulp samples exceeding 0.100 g/t Au averaging 1.16 g/t with values ranging up to 18.2 g/t. The holes tested are located east and north of the Gustavson 2020 pit-constrained resource zone along a 1,000m stretch of the N-S trending Atlanta Mine Fault zone. 

Exploration Manager Cal Herron stated: "As seen in Table 2, average gold cyanide solubility across 54 RC holes is remarkably consistent and averages 86.7%. These results clearly demonstrate that gold mineralization at Atlanta is not refractory due to sulfides or organic carbon or encapsulated by silica at fine particle size. Consequently, Nevada King's 2022 resource definition and expansion drilling program will include additional shallow RC drilling to test lower grade zones outside of the Gustavson resource zone in areas previously considered waste. The cyanide solubility tests also indicate higher-grade mineralization has higher cyanide solubility than the low-grade material. Referring to Table 3, a noticeable difference in gold solubilities is seen in the fire assay data at 1.50 g/t. Samples exceeding 1.50 g/t Au comprise 21.7% of the entire test sample population, averaging 3.88 g/t and 87.7% gold solubility. In contrast, samples running less than 1.50 g/t returned gold solubilities in the 83% range.

Our Stage 2 metallurgical testing program will therefore include conventional crush and High Pressure Grinding Roll (HPGR) comminution column leach tests on low-grade and higher-grade mineralization along the Atlanta Mine Fault zone to test the potential for heap leaching portions of the resource. Based on such encouraging gold cyanide solubility data, the Company is also expanding its cyanide testing program to include pulps from mineralized historical drill holes located west of the existing pit to determine gold solubilities within the Gustavson 2020 resource zone. Under the direction of Gary Simmons, bulk sampling within and around the pit will soon commence, together with a PQ core drilling program designed to provide samples for bottle roll and column leach testing."

Metallurgical Consultant Gary Simmons stated: "The gold cyanide solubilities reported by AAL demonstrate the consistent oxidized nature of the mineralized gold system at the Atlanta Mine. The high cyanide solubilities lead to the conclusion that cyanide leach milling and conventional crush and/or HPGR heap leach process flow sheet options are potentially viable and will be tested on PQ metallurgical core samples planned for 2022. Additional ICP sulfur (S) analysis by AAL has shown higher than anticipated S content. Upon further review, it was determined that most of the elevated ICP sulfur assays are associated with the sulfate minerals, barite and gypsum and not sulfides. Additional testing by AAL has already been designed to determine the most appropriate method to remove the sulfur contained in barite and gypsum sulfates to obtain a more representative total sulfur analysis using ICP."

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 through to the present day 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 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).
