Project Overview
Sky Gold's Evening Star Cu-Au-Ag Property is strategically located in Nevada's Walker Lane Trend, a copper, gold and silver district.
The Fraser Institute (2025 Survey) ranks Nevada second in the world for exploration and mining investment.
The Evening Star Property comprises multiple Cretaceous intrusions including granite, granodiorite, and quartz monzonite dykes, hosted alongside Triassic Pamlico Formation limestone. Historic gold mine shafts, adits, and prospect pits dating from 1870–1900 confirm the property's long-recognized mineral potential.
District Context
The Evening Star Property sits at the heart of one of North America's most productive mineral corridors. The Walker Lane Trend hosts some of Nevada's largest gold, silver, and copper deposits, several of which are actively producing or in advanced development.

Geological Model
The Evening Star Property has many of the key elements of an intact Cu-Au porphyry system as described in the Sillitoe model:
- High Life — Cu-Au porphyry system at depth, with LS epithermal breccia and open space boiling zone at surface
- Tower Gold — High-sulphidation epithermal Au-Cu-Bi veins and mineralized lithocap
- Golden Bomber — Low sulphidation epithermal quartz veining at high crustal level
- Gold Bug and Evening Star — Distal carbonate replacement deposits (CRD)
- Magnetic low structural corridor — Links Tower Gold to High Life as the interpreted feeder zone
Together these targets represent a spatially coherent, vertically zoned porphyry system that remains largely undrilled at depth.
Targets Overview
There are multiple gold-copper-silver targets on the Evening Star Property, each representing a distinct style of mineralization within a single, coherent porphyry system.
Tower Gold
A high sulphidation epithermal vein target in the north, associated with a mineralized lithocap and a 1.2 km NW-trending magnetic low structural corridor.
High Life
The primary copper-gold porphyry target. A large, deeply-rooted magnetic anomaly interpreted as the potassic core of an intact Cu-Au porphyry system.
Good Hope
Gold in quartz veining, located on the eastern margin of the High Life porphyry system.
Golden Bomber
Intermediate sulphidation chalcedonic veining with high-grade gold and copper values. Low sulphidation epithermal vein style, high-level expression above the porphyry.
Gold Bug
Skarn and carbonate replacement deposit (CRD) mineralization with historic bonanza-grade gold in quartz veins and significant base metal intercepts in historic drilling.
Evening Star
Contact-related mineralization, like La Panta, located in the south of the property within Triassic limestone at its contact with granodiorite.
High Life — The Porphyry Core
High Life is the central target of the Evening Star Property and the interpreted core of an intact copper-gold porphyry system. Multiple independent geophysical surveys — magnetic, IP, and gravity — produce overlapping anomalies that are consistent with a large, deeply-rooted potassic core directly beneath the surface expressions of the system.
Magnetic Anomaly
Following inversion of drone-supported magnetic survey data (195 line-km flown by MWH Geo-Surveys at 25m elevation and 50m line spacing), the resulting 3D isoshells display a large, 1-kilometer across, strongly-magnetic anomaly at High Life.
The interpreted magnetic potassic core is deeply-rooted and reaches towards the surface with multiple apophyses. The High Life magnetic inversion isoshells have significant values ranging from 0.015 to 0.025 cgs — comparable to the potassic core of Mt. Milligan (BC), a producing copper-gold porphyry mine, which has isoshell values of 0.02 to 0.05 cgs.
Quartz-monzonite dykes occur directly over top of the High Life positive magnetic anomaly, and surrounding High Life in a 3 km-diameter ring are additional positive magnetic anomalies representing new targets.
"High-grade Cu-Au mineralization in porphyry systems is characteristically found in the apophyses of the intrusive body — and explorationists should seek to identify buried intrusion apophyses as the most favoured targets."
— Corbett, 2009
IP Survey Results
Induced polarization (IP) surveying at High Life reveals a compelling geophysical signature consistent with a zoned porphyry system:
- A large, greater than 1 km diameter resistivity high anomaly overlies the interpreted potassic core, surrounded by a conductive outer ring indicative of phyllic alteration.
- Chargeability highs are coincident with the interpreted potassic core, suggesting disseminated sulphide mineralization at depth.
This resistivity high with conductive outer ring pattern is recognized at other Cu-Au porphyry systems worldwide, including Tupinda Cu-Au-Mo in the Tabar Islands, Papua New Guinea.
Gravity Survey
A 2020 gravity survey by Magee Geophysics identified strong gravity high anomalies at High Life, Gold Bug, and Evening Star. A gravity high indicates high density material, suggesting large volumes of metallic sulphides at depth.
At High Life, the gravity anomaly coincides spatially with the resistivity high and chargeability high from the IP survey, and with the magnetic inversion potassic core — creating a triple geophysical anomaly that is the primary drill target.
Geochemistry
Surface geochemical sampling across High Life shows strong, spatially coherent anomalies in gold, copper, bismuth, arsenic, and molybdenum in both rock and soil samples — all converging on the same area defined by the triple geophysical anomaly.
Notably, a negative manganese halo coincides with the interpreted high-grade core, consistent with observations made by Dr. Steve Garwin in other Cu-Au porphyry systems where negative Mn anomalies mark the highest-grade zones.
Quartz monzonite dykes at surface are the direct surface expression of the strongly magnetic core of the porphyry system that is just below the surface.
Boiling Zone
At High Life, drusy quartz veins with large quartz crystals, open space brecciation, and chalcedonic quartz strongly suggest a boiling zone epithermal vein system above the Cu-Au porphyry cupola. Quartz monzonite dykes with copper oxides are exposed at surface, and gold in quartz veining has been sampled at the adjacent Good Hope showing.
Gold Bug, Golden Bomber & Tower Gold
Gold Bug — Skarn and CRD
Gold Bug has skarn and carbonate replacement deposit (CRD) mineralization, with bonanza-grade gold visible in quartz veins from surface. Multiple historic adits are visible on the hill, reflecting significant past mining activity.
In 2017, drill hole ES-17-02 returned 7.5m at 3.6% Cu and 75 ppm Ag from surface.
In 1970, a deep hole drilled by Hrayr Agnerian to a depth of 169m at -45° dip southwest from Gold Bug intersected:
0.22% Cu, 3.241% Pb, 1.41% Zn and 2.46 oz/t Ag over 166m
Historic core was not analyzed for gold.
Alteration at Gold Bug includes proximal garnet with copper, and distal epidote and vesuvianite between the Gold Bug and Evening Star targets — a classic CRD alteration zonation.
Golden Bomber
Vein material from Golden Bomber is characterized by microcrystalline chalcedonic quartz — sugary, locally vuggy, and low temperature — indicating a low sulphidation (LS) epithermal vein at shallow crustal level. Chrysocolla, malachite, and azurite are the copper expression of this oxidized LS vein, which sits typically above or lateral to a Cu-Au porphyry. Some samples also carry uranium, which suggests a fertile Cu-Au porphyry system at depth.
A 2025 trench at Golden Bomber returned 4.0m of 9.80 g/t Au from a vein striking 320° with a shallow dip. A subparallel quartz vein sampled in 2018 returned 25.9 g/t Au, 102 ppm Ag, and 1.0% Cu. A distinct linear magnetic low follows the strike of the Golden Bomber quartz veins.
Tower Gold
Tower Gold is a mineralized lithocap in the north of the property with many small historical shafts and old prospects that targeted high-grade gold and copper veinlets. At Tower Gold, the lithocap has large patches of silica flooding with copper mineralization and vuggy silica, glassy limonite showing strong sulphide leaching, and low-angle quartz breccia with quartz extension veins.
A strong, linear, NW-trending magnetic low connects Tower Gold to the High Life Cu-Au porphyry — interpreted as a phyllic-altered fluid pathway and a worthy drill target in its own right.
"Every lithocap has a feeder zone."
— Jeffrey HedenquistThe big prize is the zone of mineralization beneath this lithocap hosted within a major structure.
Breccia Pipe Target
Between the High Life and Good Hope targets, channel sampling of breccia outcrops with strong argillic alteration has returned exceptional high-grade results:
CS-23: 20.3 g/t Au, 82.4 ppm Ag, 813 ppm Bi
CS-24: 6.16 g/t Au, 29.4 ppm Ag, 246 ppm Bi, 0.1% Cu
CS-25: 5.49 g/t Au, 1.4 ppm Ag, 74 ppm Bi, 0.2% Cu
The reddish and grey breccias with strong argillic alteration and elevated bismuth are consistent with a breccia pipe target.
Current Status
Management is currently assessing the work completed at Evening Star and determining the next best step.
2026 Drilling Results
In July 2026, Sky Gold Corp reported gold and multi-element assay results from drill core, rock, vein and soil sampling on the 100%-owned Evening Star Project. Four drill holes (ES-26-01 through ES-26-04) were completed, totaling 765.9 meters of core drilling.
"These are encouraging results to follow up on which have now led us to a new approach at High Life alongside strong polymetallic gold trends ready for drilling at Good Hope and Golden Bomber."

High Life — 2026 Drilling Results
Results from 3D magnetic and IP surveys suggested a porphyry system 1 kilometer in diameter at High Life. Two drill holes (ES-26-01 and ES-26-02) were completed to test for mineralization. The ground proved challenging to drill, with deeply oxidized core and a water table approximately 120 meters from surface.
ES-26-01
17.8-meter wide interval of silicification with iron oxides and minor secondary copper minerals, cutting granodiorite rocks from 108.8 to 126.5 meters downhole.
Anomalous gold: up to 44 ppb Au
Copper: up to 0.11% Cu
ES-26-02
13.8-meter wide zone of anomalous gold, up to 84 ppb Au.
Combined with results from surface soil, subcrop and outcrop geochemical sampling, a northwest gold trend emerged that is 140 meters long, presenting a new drill target and a new approach to testing the High Life porphyry.
Good Hope — 2026 Results
The Good Hope trend is a promising drill target with almost 500-meter strike length. The zone of mineralization ranges from 0.9 to 3.1 meters in width.
Grab sampling directly east of Good Hope: up to 48.56 g/t Au — the highest gold value on the property to date, further expanding on the mineralized footprint.
Note: The Company cautions that grab samples are selective by nature and are not necessarily representative of the mineralization hosted on the property. These results are used to identify the presence of mineralization and to prioritize future drilling targets.
Golden Bomber — 2026 Results
Soil sampling at Golden Bomber highlights a 300-meter northwest gold-copper-lead-silver trend (Walker Lane trend) that correlates well with recent rock sampling results.
Surface sampling results: 14.98 g/t Au and 9.23 g/t Au
Golden Bomber has never been drill tested.
CRD Hill — 2026 Drilling Results
ES-26-03 was drilled into CRD Hill, where multiple manto-like gossans were found on surface. This hole attempted to redrill the historic (1969) Agnerian drill hole. Although the surface of the hole looked promising, it seemed to veer away from the manto trend and did not return anything of interest. Possibly the azimuth of the historic hole did not take into account magnetic declination, which would make a difference of about 5 degrees.
Surface Sampling
Manto on the north side of CRD Hill (Sample 1070543):
2.26% Cu, 31.5 ppm Ag, 454 ppm Bi, and 2.49% Zn
Gold Bug — 2026 Drilling Results
ES-26-04 was the first ever hole into the Gold Bug mine, where historically (1890–1924) up to 400 ounces of gold plus copper were recovered.
Drill Core Results
12-meter wide zone of anomalous gold, silver and copper, starting at 10.7 meters downhole.
Average values: 5 ppm Ag and 0.13% Cu
Peak gold: up to 0.219 g/t Au over 1.5 m
Rock Chip and Grab Sampling
Sample 1070710 (quartz breccia from outcrop at mine entrance): 5.14 g/t Au, 214 ppm Ag, 1.25% Cu, 4199 ppm Bi
Sample 1070557 (5 cm quartz vein subcropping 100 meters east of mine): 5.71 g/t Au, 264 ppm Ag, 3.74% Cu, 0.60% Pb, 3270 ppm Bi
