NevGold Samples 1.22% Copper and 8.19 g/t Gold And Defines 4-Km Long Copper-Gold-Silver Trend At The Zeus Copper Project in The Hercules Copper District, Idaho

Rhea-AI Summary

NevGold Corp. has announced high-grade copper, gold, and silver mineralization at the Zeus Copper Project in Idaho. Samples include ZRS-07 with 1.22% copper, 8.19 g/t gold, and 21.9 g/t silver. The results indicate significant copper porphyry potential, similar to Hercules Silver's discovery. NevGold plans further surface geochemical sampling and geophysical surveys to identify drill targets. Key areas like Thorn Springs, Mortimer, and Golden Goose have shown promising results, with Mortimer extending a 4-km mineralized trend. Modern exploration will continue to define the project's potential.

Positive

• High-grade surface sampling results confirming significant copper porphyry potential.
• Discovery of widespread copper-gold-silver mineralization across the project.
• Promising sample results: ZRS-07 with 1.22% copper, 8.19 g/t gold, 21.9 g/t silver.
• Preliminary work identifying at least five targets within the Zeus Project.
• Plan for detailed and systematic sampling and geologic mapping during summer 2024.

Negative

• High exploration costs associated with comprehensive surface geochemical sampling and geophysical surveys.

Vancouver, British Columbia, June 20, 2024 (GLOBE NEWSWIRE) -- NevGold Corp. (“NevGold” or the “Company”) (TSXV:NAU) (OTCQX:NAUFF) (Frankfurt:5E50) is pleased to announce that it has identified high-grade copper, gold, and silver mineralization at surface at the newly staked Zeus Copper Project (“Zeus”, “Zeus Project”) in the emerging Hercules Copper District of southwestern Idaho. The positive sampling results highlight the significant copper porphyry potential at Zeus. As detailed in NevGold’s News Release dated April 18, 2024 (see NevGold News Release dated April 18, 2024), there are many similar geological characteristics between Hercules Silver Corp.’s (“Hercules Silver”, TSXV:BIG) copper porphyry discovery at the Hercules Project (see Hercules Silver News Release dated October 10, 2023), and the Zeus Copper Project. NevGold will continue its active field program at Zeus throughout the summer.

NevGold CEO, Brandon Bonifacio, comments: “The initial results from sampling completed at Zeus have yielded exceptional results, further validating the copper porphyry potential at the Project. The initial samples were taken as our Team was completing the project claim staking and the results have identified widespread copper-gold-silver mineralization across the entire project. With our project knowledge improving with each day spent in the field, we continue to confirm that Zeus has significant copper porphyry potential and that there may be multiple target areas or a potential cluster of copper deposits at the Project. We are diligently advancing other field work with the goal of arriving at drill targets over the coming months.”

NevGold VP Exploration, Derick Unger, comments: “Our compilation of geologic data and initial sampling has established multiple target areas and indicates that there is widespread mineralization at the Zeus Project. The presence of high-grade to highly anomalous values of copper, gold and silver confirms that the Zeus Project has strong potential to host a major porphyry copper system. Additionally, the fact that mineralization is widely scattered over the entire property, in multiple target areas, suggests the possibility of a cluster of copper deposits. This first group of surface samples was completed while we were staking the mineral claims at Zeus. We plan to complete a much more detailed and systematic program of sampling and geologic mapping during this summer field season.”

Zeus – Identified Target Areas

The preliminary rock chip sampling by NevGold, as well as historical sampling (Henricksen, 1975) and compilation of geologic data, has identified at least five targets within the Zeus Project. This preliminary work indicates a large footprint of mineralization and potential for multiple copper porphyry producing intrusive centers.

Thorn Springs

The Thorn Springs Target is the site of a large porphyry copper style alteration zone (Figure 5) that was first identified by Henricksen (1975). Sampling by Henricksen and NevGold (ZRS-07: 1.22% copper, 8.19 g/t gold, 21.9 g/t silver) has identified significant copper-gold-silver mineralization. The style of alteration, strong oxidation, and presence of copper minerals suggests that erosion has exposed the top of the copper-gold mineralization and that the deposit has experienced supergene enrichment, an important process in creating high-grade copper deposits. Thorn Springs has significant soil cover and poor outcrop exposure; these conditions may conceal a much larger mineralization footprint. The use of modern exploration methods, including soil geochemistry and high-resolution geophysics, will be key to identifying mineralization that may have been missed by previous prospectors. A significant portion of the Thorn Springs Target is located on land managed by the Bureau of Land Management (“BLM”) and could be drill tested with an Exploration Notice permit, which takes approximately 4-6 weeks to complete.

Figure 5 – Thorn Springs Target map of porphyry copper alteration (modified from Henricksen, 1975) with samples collected by NevGold and Henricksen. The alteration pattern is typical of porphyry copper deposits and indicates the erosional level is at the top of the porphyry system (see insert of “Porphyry Copper Alteration Model”, modified from Lowell and Guilbert, 1970 and John et. al., 2010). Strongly developed oxidation suggests supergene enrichment has increased the grades of the primary copper mineralization. To view image please click here

Mortimer

The Mortimer Target is the southern most exposure of a 4-kilometer trend of copper-gold-silver mineralization that extends north-northeast to the Abundance Target. The target includes the area around the historical Mortimer Mine where significant skarn mineralization has been observed in open cuts, mine dumps, and outcrops. Multiple samples (Figure 6) have shown 0.8-1.3% copper in marble, magnetite, and intrusive rocks associated with the skarn.

Iron Mountain

The Iron Mountain Target is located along the northeast continuation of the Mortimer-Abundance Trend and shows highly anomalous copper values in Triassic intrusive rocks as well as a large amount of mapped Huntington Formation, the formation that hosts copper mineralization at Hercules Silver’s copper porphyry discovery at the Hercules Project. The work by Henricksen (1975) identified hornfels metavolcanic and metasedimentary host rocks that were intruded by Triassic dikes and plutons. Henricksen (1975) also reported “unusually large concentrations of sulfides” including the copper mineral chalcopyrite and the zinc mineral sphalerite. The many geologic similarities to the Hercules Project suggests that the area has strong potential to host a blind porphyry copper deposit.

Abundance

The Abundance Target is defined by a 0.6-kilometer geochemical trend of copper up to 0.25% situated in the northeastern extension of the 4-kilometer Mortimer-Abundance Trend. The zone is hosted within the metasediments of the Weatherby Formation, a known cover unit emplaced by the Bayhorse Thrust Fault. The underlying andesitic volcanics of the Lower Huntington Formation are rich in iron, which is a critical factor for intruding porphyritic plutons to host potentially economically recoverable mineralization. Additionally, Henricksen (1975) reported the presence of supergene copper enrichment in a now collapsed adit of the Abundance Mine. This area has many analogous attributes to the blind porphyry copper deposit discovered by Hercules Silver at the Hercules Project.

Golden Goose

Rock chip samples from the Golden Goose Target, named after Golden Goose Canyon, which lies just to the west, contained some of the highest silver values (114 g/t) and gold values (1.03 g/t) identified at Zeus to date. This area is similar to the Abundance Target in that the Weatherby Formation is emplaced by the Bayhorse Thrust Fault over the Huntington Formation. This area also has the potential to contain a blind porphyry copper deposit similar to that which was discovered by Hercules Silver.
