Overview
The Nugget stock, the second largest intrusion on the Dublin Gulch Property (second only the Dublin Gulch Stock that hosts the Eagle Gold Mine), consists of an approximately 2.2-kilometre by 1.2-kilometre, medium to coarse grained granodiorite of mid-Cretaceous age. The Nugget stock is hosted in Earn group and Keno Hill Quartzite metasediments. Coincident arsenic + gold soil anomalies occur along the contact margins of the Nugget stock. The Nugget intrusion is akin to the Eagle Deposit host rock, and has been the subject of limited historic exploration work due to historic inaccessibility of the area. Starting in 2017 an access trail was constructed and has, for the first time ever, allowed vehicular access to this high-priority Dublin Gulch Gold Camp target.
Historically, a gold-in-soils geochemical anomaly that graded from trace up to 1.12 g/t Au in soils has been defined along with associated first pass trench samples that graded from trace up to 2.38 g/t Au and grab samples from trace up to 1.35 g/t Au.
A grab sample collected in 2017 from a vein uncovered during Nugget access construction consisted of primarily galena and returned values of 1,440 g/t Ag, 63.44 % Pb, 1.435 % Zn. Another 2017 grab sample from a vein consisting of primarily sulphosalts (jamesonite) returned values of 0.515 g/t Au, 82 g/t Ag 20.3% Pb, 8.34 % Sb, and 4.2 % As. Lastly, a 2017 grab sample from an historic trench on the Nugget stock returned 0.202 g/t Au, 3.7 g/t Ag and 1.3 % As.
Mineralization encountered thus far consists of quartz-arsenopyrite and polymetallic veins occurring peripheral to and within the Nugget stock.
Highlighted results from NG18-006C include:
- 101.5m of 0.57 g/t Au from 3.4 m
- 47.6m of 0.99 g/t Au from 24.4m
- 33.0m of 1.03 g/t Au from 61.8m
- Including 10.1m of 2.79 g/t Au from 61.8m
Mineralization encountered thus far consists of polymetallic veins occurring within the host rocks peripheral to the Nugget stock as well as disseminated arsenopyrite within in the granodiorite.
